3.0 AIR CONDITIONING AND MECHANICAL VENTILATION (ACMV) SERVICES
3.1 GENERAL
The purpose of the air conditioning and mechanical ventilation systems is to create a comfortable
and safe environment for the occupants as well as providing effective heat removal from M&E
equipment.
Maintaining good indoor air quality in terms of temperature, humidity, air movement, air filtration
and contaminant control will be a prime concern.
The ACMV installation should not create undue noise and vibration to the premises. Special
attention will thus be given to noise and vibration control to ACMV equipment and sensitive
areas.
As requested by the client the air-conditioning will be in the form of air Cooled chillers complete
with heat recovery. Through the use of heat rejection from the chillers, water will be heated, stored
in a tank and then distributed throughout the site.
Generally, air conditioning will be provided for Hotel guestrooms, offices, restaurants, lift lobbies,
Front of House and Back of House areas.
Mechanical ventilation will be provided for toilets, service lobby and M&E plantrooms.
A central chiller plant will provide chilled water to the development.
Automatic control and monitoring of all the ACMV equipment will generally be carried out via
Direct Digital Control (DDC) system which will be fully integrated with the BMS.
3.2 SCOPE OF WORK
The scope of the air conditioning and mechanical ventilation (ACMV) systems covers mainly the
following :
Air conditioning system comprising chilled water and air distribution systems to allguestrooms, offices, and lobby areas
Mechanical ventilation systems for toilets, kitchens and plantrooms as required Noise and Vibration Control (with advice from the acoustic consultant) Automatic Control System

3.3 SYSTEM DESCRIPTION
3.3.1 Chilled Water System
3.3.1.1 Central Chilled Water Air Conditioning System
Based on the estimated cooling load of approximately 960 kW (diversified) four 320
kW air-cooled chillers will be used. Each unit has two circuits with each compressor
and each circuit will operate independently. In general three chillers will operate at
peak load and one chiller will be for standby use. The chillers will be selected with an
extra low noise and high efficiency. For chilled water distribution to AHU /FCU this
shall be via a secondary pump with variable speed drive.
The screw type air cooled chillers are using refrigerant with non CFC such as R407c
and COP value minimum 2.8.
The air cooled chiller type will be complete with heat recovery system. The hot water
supply from the chillers will be in addition to the main hot water system.
A pair of chilled water distribution pipes (supply and return) will be installed in the
service trench around the development with branch tee-off to chilled water fan coil
units or air handling units.
3.3.1.2 Chilled Water Distribution
Ring Main Distribution loop
For a larger site, a ring main type distribution loop is appropriate, rather than a more
conventional flow and return (out-and-back) or reverse-return type pipework
distribution systems.
A distribution loop will also facilitate changes and additions to the building air
conditioning system and cooling loads.
The basic scheme would include a single size flow and return chilled water pipework.
The pipework size is approximately 50% of the initial main size of a comparable out-
and-back system for the same design pressure drop and in overall cost, the loop
pipework would be less expensive.
Chilled water flow takes place in both directions and at some point in the system there
is an equal pressure from both sides resulting in zero flow at that point. The point of
zero flow will automatically adjust to any changes in the load including addition or
deletion of air conditioning system or buildings.
Each loop is hydraulically self-balancing.
The system can be arranged with variable speed pumping using a differential control
point in the system (away from the central plant). In this case the system pressure atpart load will be decreased with lower pump energy consumed.

The chilled water pipe risers will be of reverse return arrangement with control and
balancing valves provided at each AHU, PAU and FCU for chilled water regulation.
Thermal expansion of chilled water is accommodated via a pressurisation unit.
The heat dissipation of the kitchen equipment from the condensing units will be cooled
by using chilled water.

No tariff Available throughout the year with somefluctuation in proportion to the hoteloccupancy levels
This is a recognisedenvironmentally sustainableapproach to water management.
The Environmental ImpactAssessment Report proposes thatrecycling of water is adopted forthis project
Well Water No tariff (?) Subject to confirmation by a local wellcontractor or by pilot well. It is likely
that ground water would be availablethroughout the year
It is not clear if a tariff may beapplied by the authority with
jurisdiction
The quality of the water would needto be confirmed
The rate of water extraction and thedistance between wells may besubject to limits
5.3.2 Sewage Treatment Plant (STP) and Recycled Water
The use of an STP would offer benefits:
The discharge water from the STP can be recycled for use within the development and therefore
realise savings in the PDAM or well water consumption and will be used for irrigation.
The potential savings on utility costs is very favourable to the use of an STP with recycled water
and an STP is proposed for this project.
There are a number of alternative STP systems that could be adopted including:
Extended Aeration Membrane Bioreactor Rotating Biological Contactor Fibre Capsule Package Tank Anerobic Baffled ReactorThere are pros and cons for each type of system. The Meinhardt preferred option would be the use
of the Fibre Capsule Package Tank.
This system requires a minimum of maintenance and can be buried below ground (for example,
under a car park area or under landscape area) with limited civil engineering work.
The client has expressed their preferred option is to use an Anerobic Baffled Reactor (ABR)
system due to their existing and working knowledge of the ABR system. To this end we have
adopted the ABR system into our designs.

5.3.3 Well Water
To determine whether the use of well water would be viable, the following would need to be
understood:
The quality of the water would need to be confirmed to provide exact water treatment Is a suitable aquifer available within the site Quality of well water Any limits on well water extraction rate If two or more wells are provided, is there a minimum distance between wells Is a tariff/charge applied to the extraction of well waterExperience in Jakarta shows that, for deep wells, the water extraction rate is limited to
approximately 200 Ltr/min.
The sinking of deep wells in Jakarta is now positively discouraged due to invasion of brackish/sea
water and general lowering of ground levels.
5.4 SYSTEM DESCRIPTION
5.4.1 Water Sources
Domestic cold water system will be provided for the whole development. The main water source
will be direct from the PDAM city water main and well water as an alternative source or as back

Recycled Water(from STP)
Recycled Water 115 m3(one day storage) * Garden floor
Due to the increased size of the site through further land purchases the extent of irrigation and tank size is yetto be finalized.
5.4.3 Cold Water Supply System
City main water will be treated by centralized water treatment plant before entering the treated
water storage tank. The water treatment plant will consist of sand filters, carbon filters and
chlorination.
Potable water will be provided to through use of a packaged reverse osmosis system installed in
the main pump room.
The distribution system will be completed with pneumatic booster pumps to maintain the pressure
where static water head is inadequate for the fixture operation.
Water will be distributed to the laundry by booster pumps. Water softener will be included by
Laundry Specialist Contractor.
5.4.4 Hot Water Supply System
Centralized hot water system will be provided for the hotel hot water service, kitchens and the
laundry at 60C.
A secondary hot water backup system will be provided in the form of a heat recovery system from
the main air conditioning chiller plant.
Hot water boilers and storage calorifiers will be provided to generate hot water.
A minimum and maximum hydrostatic pressure of 2 bar and 4 bar respectively will be maintained
at all drawn-off points.
Duplicate hot water recirculating pumps will be installed for each group of calorifiers to ensure
full circulation within the piping reticulation system.
Pressure relief safety valve will be provided for all calorifiers.
In order to keep a balance of cold and hot water pressures, especially for the mixing valve, the cold

Sub-metering will be provided for restaurant/caf/shops and laundry etc. if necessary and these
will be located outside the associated area for easy access/maintenance.
5.4.5 Sanitary System
The proposed system will be a fully vented one pipe system (combined soil and waste stack). The
system is simple, requires less space and yet has adequate ventilation.
All the soil and waste stacks will be terminated at the roof with vent cowls.
Soil and waste pipes from the individual buildings/riser stacks will be discharged by gravity flow
to STP.
All discharge from the kitchens will be drained to grease interceptors before entering the sewage
piping services.
The retention time of grease interceptors will be in the range of 10 to 15 minutes.
The discharge from the laundry will be collected via sumps and channels to slow down the quick
discharge from the washing machines before being drained to the central sewage pipe system. The
laundry discharge will also be treated before it enters the sewage system.
5.4.6 Sewage Treatment Plant (STP)
5.4.6.1 STP Types
Conventional sewage treatment may involve a three stage process:
1. Primary treatment: Sewage is discharged to a holding tank where heavy solids cansettle and oil, grease and lighter solids float to the surface. The settled and floating
materials are removed and the remaining liquid taken to the next stage
2. Secondary treatment: Dissolved and suspended biological matter is removed. Thisprocess is typically by use of micro-organisms
3. Tertiary treatment: Can include further filtration via sand and carbon filters anddisinfection using, for example, chlorine
There are many different types of STP available in the market. All generally follow the
primary, secondary and tertiary treatment process noted above, but differ in detail in the
particular approach to each treatment stage.
The STP types generally commercially available for this type of resort hotel project
include:
Extended Aeration Membrane Bioreactor Rotating Biological Contactor (RBC)
Fibre Capsule Package Tank

kitchen/restaurant, spa and laundry water usage is approximately 174 m3. This value is
excluding water needed for irrigation.
The capacity of the STP is based on 80% of the estimated total daily water usage ie
approximately 140 m3per day.
Influent and Effluent Quality
For the purpose of design the following criteria for biological oxygen demand (BOD),
chemical oxygen demand (COD) and suspended solids (SS) will be adopted:
Influent qualityBOD : 300 mg/l
COD : 500 mg/l
SS : 300 mg/l
