main project design documentation of the reconstruction of existing boiler room and thermal station room including connection to the district heating system should be created for the University hospital for pulmonary disease Jordanovac, location Jordanovac 104 in Zagreb.

PRESENT CONDITION

The complex of buildings in University hospital for pulmonary disease Jordanovac has its own boiler room and thermal station room for heating and preparation of domestic hot water (DHW). In boiler room, four gas-fired boilers are placed and supplied with natural gas from municipal gas distribution network. Two classic hot water boilers (QH1=1200 kW from y.1996 and QH2=1160 kW from y.1978) supply heat for the load of hot water heating system, preparation of DHW and heat coils in the air handling unit. Installed heat power of the equipment connected to the boilers is in total 2190 kW, including heat exhangers in DHW tanks. Boilers operate at nominal temperature regime 90/70 oC for external design conditions. Hot water distribution piping is divided in five main circulation branches through distributors placed in thermal station room.Two steam generators (each QS1/2=180 kW from y.1978) are placed in boiler room and supply low-pressure steam for the load of equipment for sterilization and cooking. Installed heat power of the equipment connected to the boilers is in total 300 kW.Forced-draught combined gas-oil burners (from y.1978) are installed on all boilers.Extra light fuel oil is used as back-up fuel and it is stored in four outdoor tanks with total volume of 125 m3.The DHW is stored in three tanks with total volume of 15 m3 (each tank V1/2/3 = 5.000 litres) placed in thermal station room.Equipment and associated system elements mostly date from y.1978 and they are worn-out so they do not enable reliable energy supply in future, according to the requirements of health-care facilities.There is medium-pressure steam pipeline in size DN 350, placed on the adjacent parcel of the hospital KBC Zagreb – Rebro, that comes from the district heating system of power plant TE-TO, managed by the heat energy distributor HEP Toplinarstvo d.o.o.

TERMS OF REFERENCE

for

Main project design documentation of the reconstruction of two existing boiler rooms including connection to the municipal gas distribution network should be created for the Centre for education Dubrava, on location Prilaz T. Špoljara 2 in Zagreb.

PRESENT CONDITION

The buildings in Centre for education Dubrava have two separate boiler rooms with thermal stations for heating and preparation of domestic hot water (DHW) – the main boiler room and the annex boiler room. Boilers in both boiler rooms are fired with extra light fuel oil stored in outdoor tanks. Both boiler rooms are in spaces that are partiallly below ground and the distance between them is about 100 m.In the main boiler room, two classic hot water boilers (QH1=400 kW from y.2011 and QH2=510 kW) supply heat for the load of hot water heating system and preparation of DHW. Installed heat power of the equipment connected to the boilers is in total 890 kW, including heat exhangers in DHW tanks. Boilers operate at nominal temperature regime 90/70 oC for external design conditions. Hot water distribution piping is divided in nine main circulation branches through distributors. Hot water circulation for all braches is provided by one circulation pump (operating + spare).One steam generator (QS1=500 kW, 800kg/h of dry steam from y.2006) is placed in the main boiler room and supply low-pressure steam for the load of equipment in the kitchen. Installed heat power of the equipment connected to the steam boiler is in total 115 kW.Forced-draught oil burners (from y.1998 to 2006) are installed on all boilers.The DHW in the main boiler room is stored in one tank with volume of V1 = 4.000 litres.Heating system control is provided through the automatic control equipment in the boiler room by changing the water temperature with outdoor conditions.Some of the equipment and associated system elements are worn-out so they do not enable reliable energy supply in future, according to the requirements of the buildings. That is obvious especially for the new boiler QH1 (y. 2011) which is in bad condition although only 2 years old, and for DHW tank and main hot water pump.In the annex boiler room, one classic hot water boiler (QH3=510 kW from y.2006) supply heat for the load of hot water heating system, preparation of DHW and heat coils in the air handling units. Installed heat power of the equipment connected to the boiler is in total 310 kW, including heat exhangers in DHW tanks. Boilers operate at nominal temperature regime 90/70 oC for external design conditions. Hot water distribution piping is divided in four main circulation branches through distributors. Hot water circulation for all braches is provided by one circulation pump (operating + spare).Forced-draught oil burner (from y.2002) is installed on the boiler.The DHW in the annex boiler room is stored in one tank with volume of V2 = 1.000 litres.Heating system control is provided through the automatic control equipment in the boiler room by changing the water temperature with outdoor conditions.Condition of the equipment and associated system elements in the annex boiler room is generally good, because some of the worn-out equipment were recently replaced through regular maintenance. More often problems were reported with one three-way mixing control valve with servo motor drive.Heating systems connected to the boilers in both boiler rooms are not equipped with room controllers.

10

Water supply and supplement of the hot water systems in the buildings is not implemented through the water treatment equipment.Northeast from the Centre parcel, there is placed municipal gas distribution pipeline, managed by the gas distributor Gradska plinara Zagreb d.o.o. on which the boilers in boiler rooms and eventually other equipment in the Centre could be connected. Distance from the possible connection joint to the main boiler room in the Centre is about 150 m.


Partial dismantling and substitution of the equipment in the existing boiler rooms (reconstruction zone) is to be done, because of substitution of the energy carrier from oil to gas and because some of the existing equipment and controls are worn-out. The reconstruction has to include all necessary steps in converting oil-fired boiler rooms into gas-fired boiler rooms with adequte ventilation systems and with connection to the municipal gas distribution network.

A) THE MAIN BOILER ROOMThe existing equipment is to be dismantled as follows:

Thereby, parts of the equipment and some valves are to be carefully uninstalled and later installed, if they are good for later use. Distribution pipings for the energy supply of the terminal equipment outside of the reconstruction zone are outside the scope of this project. The connections to the heat sources in the boiler room are to be made at the entries to the reconstruction zone.All parts of the equipment that are good to be used on other locations are to be carefully uninstalled and transported to the locations specified by the investor.

Project design solution has to predict one new hot water boiler of adequate heat power for hot water systems (central heating, preparation of DHW) as replacement for the boiler QH1. Both hot water boilers are to be equipped with adequate force-draught gas fired burners. Design temperature regime for secondary hot water distribution is to be checked by calculation and, if possible, selected at 80/60 oC. Design has to predict complete reconstruction of hot water piping in the boiler room with adequate hydraulic balancing of the main hot water circulation branches at the distributors, for example by using manually operated balancing valves installed in the return pipes. Design has to predict hot water pumps with variable speed control, for energy efficient operation after reconstruction of distribution and terminal equipment in the later phase (outside the scope of this project). Design has to predict control energy and water meters mounted on the main branches and on connections of large consumers.

TERMS OF REFERENCE

for

Main project design documentation of the reconstruction of boiler room in the main building of Risnjak National Park, where oil burned boiler should be replaced with biomass chips burned ones.

PRESENT CONDITION

The main building of Risnjak National park was constructed in late seventies of the last century. Geographic coordinates of the building are: N45o25’06,55’’ and E14o41’08,81’’. Total area of the building is approximately 950 m2. Access to the building plot is from street in Bijela Vodica, some 14 km NW direction from Delnice exit on A6 highway. The main building is used as headquarter of the national park and consists of: basement, ground and first floor. Spaces are heated with central heating system from the boiler room in the basement. The basement consists of convention space, utility rooms and boiler room. The ground floor consists of a restaurant, reception and offices, while the upper floor consist sleeping rooms and offices. All radiators are equipped with manual control valves in the heating flow and ballasts in the return lines. The heating system is controlled automatically according to ambient

13

temperature. Heating operation is continuous, without interruption. The outer wall is made up of brick or concrete and mortar total thickness of 40 cm. Pitched roof is made of wooden structures covered with domestic shingle (poor condition). The walls are in good condition but, there is no insulation on them. Windows are wooden with double glazing all of them in poor condition with bad seals. Exterior doors are wooden with no windows. On the inside of the window, curtains were placed as protection against solar radiation.

Boiler room

Layout area of the boiler room is approximately 10 m2, a height is 2,7m. Boiler room consists of: hot water boiler: manufacturer Centrometal Croatia, type EKO-CUP S3,:boiler capacity is 240 kW

with an oil burner, year of production probably 2005 (there is no label on it), the temperature regime of the existing heating system is 80/60 oC

hot water storage tank capacity of 600 dm3, manufacturer Centrometal Croatia, type TB-600 year of production is 2005

The manifold consists of three main branches, where two of them are aimed for radiator heating and both are equipped with mixing valves and pumps. Third branch is dedicated to DHW heating. This branch is without any regulation at all, no mixing valves, nothing. Thus, the average temperature of DHW up to 75oC.

There is no daily oil fuel tank in the boiler room, but the main oil tank has been buried in the backyard since 1980. The tank's capacity is app. 12000 dm3 constructed as one wall steel tank. The tank was placed in the soil without safety pan.

chimney is common concrete structure

Central heating systemCentral heating system is constructed as double pipe heating system with the different type of radiators. The temperature regime of the existing heating system is 80/60 oC. The heating system is regulated by automatic regulation according to the outside air temperature. The heating system is mostly old and there is no data on the actual installed capacity for individual heating circuits.

Air handling units (AHU)There is no air handling units installed in the building. The kitchen hood ventilation system has been installed in the kitchen. System is in good condition, but poorly calculated and because of that it is rarely used.

Domestic hot water (DHWDomestic hot water (DHW) is used for personal hygiene in lavatories and showers, and for the preparation of food in the kitchen sink. There is one DHW accumulator with total volume of 600 dm3. Temperature in the DHW tank is not regulated, thus the average temperature of DHW is up to 75oC. Existing recycling pump is under dimensioned and piping system is not balanced (there are no balancing valves). Because of that, there is a permanent problem with DHW delivery across the building.


14

Project of reconstruction of boiler room and DHW preparation system should be prepared as a main project, equipped and consist of all parts necessary to obtain building permit. Project should start with a site inspection which gives a detailed view of the condition and energy efficiency of the surveyed building and DHW installations as well as all other important data for all parts of Project such are:

Heating, ventilation and DHW preparation Electrical Installation Construction

HEATING, VENTILATION AND DHW PREPARATION PART OF THE PROJECTIn site survey needs to deliver following results:

- Record the actual state of the installed radiators (all circles) to be able to optimize control valves sizing, circulation pumps sizing and the required power generators; within this point it is necessary to measure the flow rate of all circuits before reconstruction to allow real analysis of capabilities of the maximum initial temperature reduction (of the boiler). It is requested to measure flow rates of heating water for each single circuit in the boiler room, to be able to set them up at the same level after reconstruction.

- Record the actual state of other equipment for heating, ventilation and DHW preparation - Measure consumption of DHW and energy needed to heat DHW for at least 5 days period

(min/max/average/hourly) in order to obtain data for optimal sizing of new storage tank.

The project should:- Technical evaluation of energy efficiency of current system of heating, domestic hot water

(DHW) system, and kitchen ventilation- To design a new technical solution of the boiler room, take into account the actual data

obtained by examination and measuring; In order to save energy, reduce greenhouse gas emissions and rationalization costs of heating and hot water, design new boiler room on the way to replace type of fuel (oil to biomass chips).

- DHW heating during period out of the heating season should be solved by means of solar collectors. Since there is a LPG tank on the backyard (for kitchen), design 2 nd small boiler which should be used to heat the DHW when solar energy is not enough to heat DHW. That 2 nd boiler should be equipped with LPG burner.

- Develop technical solution dismantling of existing equipment from the basement boiler room, and buried oil tank

- There is a possibility that the restaurant will be leased, therefore project should provide installation of calorimeters to measure heating and DHW consumption

All the results of the observations, measurements and calculations should be described in the project of reconstruction.

Guiding values of thermal loadAccording to architecture blueprints of the building, prepared by the company Projekt 54 from Delnice from 1978, new calculation of heat loads have been calculated assuming followed heat transfer coefficients:

external wall 1,34 W/(m2K)

15

internal wall 1,90 W/(m2K) window 3,00 W/(m2K) floor 1,50 W/(m2K) internal door 2,5W/(m2K) roof 1,16 W/(m2K)

Winter project temperature for Bijela Voda is -21 oC. Calculated heat transmition loads are 94,89 kW.

Ventilation lost have been calculated based on fresh volume air exchange, where for all rooms except toilets, wardrobe, kitchen and restaurant, 0,5 volume exchanges per hour was selected as amount of fresh air intake. Volume exchanges per hour for the toilets have been selected to 8, for wardrobe to 4, and for restaurant to 2. Calculated ventilation loads are 53,2 kW!!!

Total heat load for winter season was calculated according to EN12831 is 148,09 kW, taking into account with engineers security mistake of 15 % (for calculations done in late seventies of the last century), total heat load is accepted to 170,3kW.

To calculated value of 170 kW, amount for preheating DHW should be added. Assuming that volume of 600 dm3 should be heated from 10oC to 55 oC in two hours, additional 17kW should be added to total heat boiler capacity. New boiler should be dimensioned to at least 170kW+17kW=187kW.

Warehousing and distribution of FuelOil Fuel economy Existing buried oil storage of unknown capacity, approximately 12000 dm3is old and in bad shape, as well as the corresponding manifolds for supplying fuel oil to the boiler. Project design should include the necessary work of dismantling and disposal of tank, pipeline, and environmental remediation. Existing oil manifold should be excluded from further use.Gas installationReconstruction of boiler room should cover measured gas installation pipeline and connection to the existing LPG pipeline.

Calculation of gas installations

Calculation of the gas system comprises:

determining the necessary volumes of for DHW heating during out of the heating season period

pipeline sizing Boiler room

New hot water boilers should be installed in boiler room, where the total power will be defined after the recording of necessary consumption. Total power for future boiler does not exceed the maximum required power. The 1st boiler should cover 100% of energy needs for heating and DHW and should be burned on biomass chips. 2nd boiler should be used to heat the DHW during out of the heating season, and when solar energy is not enough to heat DHW. That 2 nd boiler should be equipped with LPG burner and could be facade design with capacity of 30kW.

16

Complete heating water pipeline, with all the shut-off and control equipment should be replaced. Active and reserve pump should be provided for each heating circuit. Equipment and pipes should be insulated to reduce heat loss. Minimum insulation thickness should be conducted in accordance with the requirements of technical regulations. Ventilation of boiler room New boiler room should be ventilated by means of natural ventilation (diagonal slots in the boiler room). Vents, windows and channels designed according to the conditions stipulated in the Ordinance, and control calculations show that the minimum technical requirements are met.

DHW systemDistribution and DHW heating should be done in the basement as a part of existing boiler room. DHW system sizing should be provided based on actual consumption measurements (DHW accumulator should be over dimensioned for amount of 20% comparing to measured data). The calculation should take all necessary amount of hot water for kitchen, laundry and hand basins, showers and bathtubs in the toilets.

Existing DHW manifolds should be equipped by regulating valves, and balanced.

The new flat plate solar collector system should be calculated and predicted to cover DHW consumption during summer months. Thus, DHW tank should be selected as a bivalent one.

Chimney Each boiler has to be equipped with its own chimney. Control calculations should be done according to EN 13 084 / DIN 4133. Calculation of the chimney should be an integral part of the project.

Gas detection systemInfrared sensors for gas detection should be installed above the potential sources of leakage of gas. Gas detection system should be connected to the control unit of remote monitoring system.

Above mentioned four air handling units are outdated (age of the existing air handling units is from 22 to 26 years) and do not have heat recovery section.The reconstruction aim: energy savings (using sensible heat from exhaust air), increasing indoor thermal comfort in the conditioned space, air dehumidification in the swimming pool space in the building Hydrotherapy Children's department.

1A) Air handling unit for air conditioning of the swimming pool and wardrobe space in the building Hydrotherapy Children's department

PRESENT CONDITION

20

Air conditioning of the swimming pool and wardrobe space in the building Hydrotherapy - Children's department was performed using air handling unit. The following data on the air handling unit are known:

Manufacturer: IMP KLIMAT Ljubljana

Type: KND 6,3 d

Year of construction: 1991.

Nominal air flow - supply side: 4.000 m3/h

Nominal air flow - exhaust side: 4.000 m3/h

Heat transfer rate of heater (90/70°C): 73 kW

Electrical power of supply fan: 1,7 / 0,6 kW

Electrical power of exhaust fan: 1,7 / 0,6 kW

The main components of the existing air handling unit are: filter, heater, supply and exhaust fan.

Heat source for the heater is hot water (90/70°C) produced in boilers of the manufacturer TOPLOTA on natural gas, which are placed in the central boiler room. The existing air handling unit is 22 years old, has no built-in heat recovery section and is placed inside the basement-ground machinery room surface area 8,5 m x 11 m = 93,5 m2.

Entrance to the machinery room from the outside is provided directly over the access corridor width of 1,25 m. Outside metal door has opening height of 2,02 m and opening width of 0,97 m, while inside metal door has opening height of 1,83 m and opening width of 0,695 m.

The space of the machinery room, where the existing air handling unit is placed, is loaded with moisture due to overflow of the water from the swimming pool through the space of machinery room. Part of the thermal insulation of the supply and exhaust duct is in extremely poor condition (cracked and crumbled).


With regard to the age and inefficiency of the existing air handling units main project design documentation for air conditioning of the swimming pool and wardrobe place in the building Hydrotherapy Child's department should be created.

The existing air handling unit and distribution channels are need to be completely disassembled and replaced with new air handling unit containing heat recovery section and new distribution channels with new air diffusers.

For the purpose of air conditioning of the swimming pool area the main project design solution has to predict installation of new air handling unit containing equipped with high efficiency recuperator (plate heat exchanger) with sensible heat recovery efficiency of at least 70 % and electrically driven heat pump with environmentally friendly refrigerant.

The airflow leaving the swimming pool area (extract air) will be cooled down on the evaporator surface of the integrated heat pump with the main aim of dehumidifying of air in the swimming pool area.

21

Beside already mentioned component the new air handling unit should also contain filters, supply and exhaust fan and additional heater (55/45 °C). Recuperator and all other material, which will be used in air conditioning system, should be durable and resistant to aggressive compounds that may occur in the airflow (e.g. recuperator made of polypropylene).

New air handling unit must be connected to a central monitoring and control system where all important parameters can be controlled and read.

Entering the new air handling unit in the existing machinery room should be predicted in parts over the access corridor opening width of 1,25 m (Outside metal door has opening height of 2,02 m and opening width of 0,97 m, while inside metal door has opening height of 1,83 m and opening width of 0,695 m).

Due to old channel distribution the complete existing channel distribution, diffusers and regulation need to be also disassembled and replaced.

Completely new distribution channel, dimensions according to dimensioning calculation, with all ductwork and duct connection components, diffusers and duct dumpers need to be performed.

The air conditioning system needs to be dimensioned according to air pollution with moisture in the swimming pool area (VDI 2089 Part 1 - Building Services in swimming baths - Indoor pools).

Volume of water in the children's pool is 50 m3, and the pool water's temperature is 30 °C (room temperature of indoor pool range from 2 up to 4 °C above the pool water's temperature).

Ventilation of the machinery room, where the existing air handling unit is placed and where also the new air handling unit will be placed, should also be solved with the same main design.

1B) Air handling unit for air conditioning of the restaurant space in the high ground floor of the building NBO (NBO - Novi Bolnički Odjel) (due to failure air handling unit is not working anymore)

PRESENT CONDITION

The restaurant in the high ground floor in the building NBO is conditioned with the one air handling unit.

The main component of the existing air handling unit are: filter, two heaters, supply and exhaust (5,5 kW) fan. Heat source for the two heaters is hot water (90/70°C) produced in boilers of the manufacturer TOPLOTA on natural gas, which are placed in the central boiler room. The existing air handling unit has no built-in heat recovery section. Due to age and failure the existing air handling units is no longer in operation (one heater leaked).

Technical data are not known (there is no technical documentation)!

Since the technical data of existing air handling unit are not known, the external dimensions of air handling unit are measured (1,245 m x 1,245 m = 1,55 m2), and assuming the air flow speed in the air handling unit in the amount of 2 m/s, approximated value of the air flow in the amount of 11.000 m3/h is calculated. Approximately the same value of air flow can be obtained using the cross section of exhaust channel 1,12 m x 0,55 m = 0,616 m2 and assumed air velocity in the exhaust duct in the amount of 5 m/s.

22

The air handling unit is placed inside the basement machinery room surface area 6,1 m x 9,75 m = 59,5 m2 and the height of 1,88 m.


With regard to the failure and inefficiency of the existing air handling units main project design documentation for air conditioning of the restaurant place in the NBO building should be created.

The existing air handling unit and distribution channels are need to be completely disassembled and replaced with new air handling containing heat recovery section and new distribution channels with new air diffusers.

For the purposes of ventilation, heating and cooling of the restaurant on the ground floor of the building NBO the main project design solution has to predict installation of a new air handling unit equipped with high efficiency recuperator (plate heat exchanger) with sensible heat recovery efficiency of 70 % at least. In addition to heat recovery system the new air handling unit should also contain filters, heater (55/45 °C), cooler (7/12 °C) (connection will be made when the source of cooling energy will be available) and supply / exhaust fan frequently controlled, which will solve the optimal air supply to the normal mode or in savings mode. Heater need to be connected to the existing supply/return connection of hot water.

New air handling unit must be connected to a central monitoring and control system where all important parameters can be controlled and read.

Entering the new air handling unit in the existing machinery room should be predicted in parts over the access corridor and double door with opening width of 1,85 m and opening height of 1,88 m.

Completely new distribution channel, dimensions according to dimensioning calculation, with all ductwork and duct connection components, diffusers and duct dumpers need to be performed.

1C) Air handling unit for air conditioning of the basement in the building NBO and air handling unit for air conditioning of ground floor in the building NBO (NBO - Novi Bolnički Odjel)

PRESENT CONDITION

Air conditioning of the basement area in the building NBO was performed using one air handling unit. The following data on the air handling unit are known:

Manufacturer: IMP KLIMAT Ljubljana

Type: KND 1001B5B6A1A

Year of construction: 1987.

Nominal air flow - supply side: 7.710 m3/h

Nominal air flow - exhaust side: 7.530 m3/h

Heat transfer rate of heater (90/70°C): 53,6 kW

Electrical power of supply fan: 5,5 kW

Electrical power of exhaust fan: 5,5 kW

23

The cross area of supply / exhaust part of the existing air handling unit is 1 m x 1 m = 1 m2.

The ground floor in the building NBO is conditioned with the one air handling unit also manufactured by IMP KLIMAT Ljubljana (year of construction 1987). Technical data are not known (there is no technical documentation) ! Since the technical data of existing air handling unit for air conditioning of the ground floor are not known, the external dimensions of air handling unit are measured (1,5 m x 1,5 m = 2,25 m2), and assuming the air flow speed in the air handling unit in the amount of 2 m/s, approximated value of the air flow in the amount of 16.200 m3/h is calculated.

The main components of the two above described existing air handling units are: filter, heater, supply and exhaust fan. Heat source for the two heaters is hot water (90/70°C) produced in boilers of the manufacturer TOPLOTA on natural gas, which are placed in the central boiler room. Both air handling units are placed in the same machinery room of the surface area 3,33 m x 9,73 m = 32,4 m 2 and height in the amount of 3,2 m.

Entrance to the machinery room is provided through the metal double door with opening width of 2,03 m and opening height of 2 m.

The both existing air handling units are 26 years old, have no built-in heat recovery section and need to be replaced with new air handling units.


With regard to the age and inefficiency of the existing air handling units it is necessary to replace them with two new air handling units both equipped with heat recovery section. The existing distribution channels in the ground floor should be also completely disassembled and replaced with the new one.

For the purposes of ventilation, heating and cooling of the basement and ground floor in the building NBO the main project design solution has to predict installation of two new air handling unit equipped with high efficiency recuperator (plate heat exchanger) with sensible heat recovery efficiency of 70 % at least. In addition to heat recovery system the new air handling units should also contain filters, heater (55/45 °C), cooler (7/12 °C) (connection will be made when the source of cooling energy will be available) and supply / exhaust fan frequently controlled, which will solve the optimal air supply to the normal mode or in savings mode. Heaters need to be connected to the existing supply/return connection of hot water.

New air handling units must be connected to a central monitoring and control system where all important parameters can be controlled and read.

Due to inaccessibility, dismantling of existing air handling units in the basement must be carried out in parts, as well as the installation of new air handling units.

Completely new distribution channel, dimensions according to dimensioning calculation, with all ductwork and duct connection components, diffusers and duct dumpers need to be performed. Air conditioning system needs to be dimensioned according to required air exchange rate.

24

New air handling unit for air conditioning of the basement has to be connected to the existing distribution channels after cleaning of existing distribution channels.

2. RECONSTRUCTION AND REPLACEMENT OF THE EXISTING CENTRAL DOMESTIC HOT WATER SYSTEM

PRESENT CONDITIONDomestic hot water is prepared centrally in 6 indirectly heated hot water vessels of manufacturer Buderus of total volume 4.500 L horizontally placed in a room of surface area 4,8 m x 15 m = 72 m2 in the part of boiler room situated inside the building of Old hospital. Geothermal water temperature of 40 °C enters directly into 6 vessels. Using low-pressure steam, produced in the steam boilers manufacturer TOPLOTA Zagreb on natural gas (build year 1975.), the geothermal water temperature of 40 °C is heated up to a temperature of 55 °C. Low pressure steam flows through the tube heat exchanger immersed in vessels. Steam temperature at the entrance of the heat exchanger is approximately 110 °C. In addition to indirectly heated hot water vessel the tank, which collects the condensate, is also located in the same boiler room. All equipment of the existing central domestic hot water system were carried in through one window with opening width of 0,81 m and opening height of 1,8 m.


The main project design solution has to predict the complete reconstruction of existing central domestic hot water system.

The existing hot water vessel, tank for collecting of condensate, piping which supplies steam to hot water vessels should be dismantled and replaced with new domestic hot water system (installation of new equipment and pipe distribution of hot water).

The required parameters for a new domestic hot water system:

- geothermal water temperature of 40 °C enters in the domestic hot water system (existing pipe connection of geothermal water DN 50)

- heating of domestic hot water from 40 ° to 55 °C in vessels (in order of importance) only with hot water:

1. waste heat at the condenser of heat pump water/water for cooling of geothermal spring water

2. hot water produced in the existing hot water boilers

- predict new piping distribution of hot water, as a medium for heating domestic hot water to the required temperature

For proper sizing of central domestic hot water system flow water measurement is required in a minimum period of 7 days.

New domestic hot water system must be connected to a central monitoring and control system where all important parameters can be controlled and read.

25

3. REPLACEMENT OF THE TWO EXISTING HEAT PUMPS WATER/WATER WITH TWO NEW HEAT PUMPS WATER/WATER using geothermal spring water temperature of 41 °C as a heat source with main purpose of:

- cooling geothermal spring water for filling swimming pools (Mary's swimming pool, swimming pool in the building NBO, swimming pool in the building of the Children's department)

- transferring the condenser heat in the central heating system in the heating season

- transferring the condenser heat in central domestic hot water system and for laundries in the cooling season

PRESENT CONDITION

In the Special hospital for medical rehabilitation Krapinske Toplice following swimming pools are directly filled with geothermal spring water: Jakob's and Mary's pools in the building of Hydrotherapy of Old hospital, pool in the building NBO and pool in the Children's department.

Jakob's pool is filled directly with geothermal spring water temperature of 41 ° and the cooling of geothermal water is not needed. Mary's pool, pool in the building NBO and pool in the Children's department require geothermal water temperature around 30 °C.

In summer (cooling season), geothermal spring water for filling Mary's pool, pool in the building NBO and pool in the Children's department is cooled with tap water, which is a big expense with respect to the current price of tap water (Zagorski vodovod d.o.o.). In winter (heating season) cooling of geothermal spring water is done using two electrically-driven vapour compression cycle heat pumps manufacturer GEA HAPPEL type EUWH 240 FSD (build year 1992.) with environmentally unfriendly refrigerant R22, using geothermal spring water as a heat source.

The following data on the existing two heat pumps are known:

Total heating capacity: 1.440 kW

Coefficient of performance COP: 3,6

Total compressor power to both heat pumps: 400 kW

Total cooling capacity: 1.040 kW

Supply temperature of water in the heating system: 55 °C

Data on geothermal source:

Flow of geothermal spring water source: 180 m3/h = 50 l/s

Temperature of geothermal spring water: 41 °C

Two existing heat pumps were installed in the newer part of the boiler room surface area of 7, 4 m x 15, 5 m = 114,7 m2 along with two hot water boilers on natural gas. Entrance to the newer part of boiler room is provided through metal door with opening width of 4,6 m and opening height of 2,9 m.

26

Heat transfer between the refrigerant R22 in the evaporator of heat pumps and geothermal spring water is derived indirectly via plate heat exchanger manufacturer GEA type VT 40CDL-10, which is located in a separate building near building of pumping station.

After passing through the existing plate heat exchanger cooled geothermal water flows to the tank of cooled geothermal water, and then flows to pools. Excess of cooled geothermal water is spilled into creek. Condensator heat is delivered to the central heating system in the heating season. Waste water of all pools in Special hospital for medical rehabilitation Krapinske Toplice is spilling to the creek throughout whole year.

Refrigerant R22 (chlordifluormethane, CHF2Cl) is an environmentally unfriendly refrigerant, which according to Regulation on substances which deplete the ozone layer and fluorinated greenhouse gases (OG 92/12) can be placed on the market in Croatia and used for the maintenance or servicing of existing chillers, air conditioning equipment and heat pumps by 31st December 2014.


With regard to the age and inefficiency (low COP) of two existing heat pumps with environmentally unfriendly refrigerant R22 it is necessary to dissemble them and replace them with two new heat pumps water/water. Used oil should be disposed and refrigerant R22 should be recuperated and reused for another systems still using R22.

The main project design solution has to predict installation of two new energy efficient heat pumps water/water using as a heat source geothermal spring water of following parameters:

Flow of geothermal spring water source: 180 m3/h = 50 l/s

Temperature of geothermal spring water: 41 °C

The required parameters for new heat pumps water/water:

- coefficient of performance COP = 5 and more

- heat pumps for use with water heat source from 20 to 35 °C

- supply temp. of water in the central heating system, domestic hot water system min. 65 °C

- environmentally friendly refrigerant.

Condensator heat of heat pumps should be stored in tank and used in:

- HEATING SEASON for central heating system

- COOLING SEASON for central domestic hot water and for laundries (preheating of water at the entrance to the washing machines)

The main project design solution has to predict also installation of cooling towers to ensure the eventual disclosure of excess heat into the environment.

Heat transfer between geothermal spring water and refrigerant in the evaporator of heat pump should be derived indirectly through heat exchanger.

27

One heat pump needs to be dimensioned to the needs in heating season (central domestic hot water and laundry).

To determine the need for laundry the report on conducted walk through audit titled Previous energy analyzes for efficiency project in the Special hospital for medical rehabilitation Krapinske Toplice from June 2010 should be used.

New heat pumps must be connected to a central monitoring and control system where all important parameters can be controlled and read.

Interior construction worksProject design solution of architectural and construction works in the interior of the reconstruction zone has to be created, to provide functional space with all necessary features for mechanical rooms. Definition of the interior features is to be cleared with the investor, taking into account the functionality.

Electrical installationsProject design solution of electrical installations, including all new equipment, wiring and lighting in all rooms in the reconstruction zone has to be created. Also, possible reconstruction or adjustment of the main distribution board has to be included.

This project design solution has to be created taking into account optimal and modern technical solutions and state-of-the-art equipment.
