GeneralThe LPCA-RMB series air-cooled water chillers consists of 12models covering capacities from 188.2 up to 597.9 Kw.It is the end result of a thorough study, and accurate design byexperienced Interklima research and development teams, todevelop a large size chiller series with compact shape, highperformance, and reliability of the highest quality standards.This series meets the highest levels of aesthetic and technicalrequirements using the latest technological innovations includingenvironmentally friendly R407c refrigerant that is Chlorine-freeand has zero ozone depletion potential. LPCA-RMB units aretherefore ideal for installation in urban environments due to theirelegant design, selected materials and low operating sound levels.

CasingAll units use metal parts fabricated from heavy gauge galvanizedsteel sheets, formed to ensure maximum rigidity that guaranteesand preserves the units operation during the years. Afterfabrication these are degreased, phosphatised, andelectrostatically powder coated with an epoxy-polyester RAL 9002coating of a thickness 60-70 Ì. This fully automatic processensures superior corrosion resistance against the mostaggressive ambient conditions. The treatment can successfullywithstand a salt spray test of 500 hours, according to ASTM B-117. All components are assembled together using bolts thusavoiding the need for welding which may harm the galvanizationof the steel, and ensures that the whole assembly can fullywithstand adverse weather conditions.The compact footprint of the unit arises from detailed study anddesign by our engineering teams and results in a machine, whichfits easily in restricted areas and is simple and easy to install andmaintain, and has been designed with special fittings for easytransport and lifting.Removable side panels are used to permit access only toauthorized personnel to internal components of the unit forinspection and maintenance. Electrical and electronic equipmentand components for proper unit operation are located in a weatherproof (IP 55) electrical panel with access via only a special key.

CompressorAll units’ use low-noise, maintenance free, Hermetic Tandem Scrollcompressors with low vibration levels, specially optimized for usewith R407c refrigerant, selected from world class suppliers.They are equipped with a crankcase electrical heater for the oil, andare internally protected against potential overloading or electricalspikes. The compressors are mounted on special antivibrationrubber mounts to eliminate vibration from the unit’s operation.

Air heat exchanger All unit air heat exchangers are manufactured from high qualitycopper inner grooved seamless tubes according to ASTM B-280,having an outside diameter of 9,52 mm (3/8"). The fins aremanufactured from aluminium and form the secondary extendedheat transfer surface. The fins are continuous across the heatexchanger and are fabricated in high precision dedicated presslines. The fin surface is waffle formed, so as to increase the finrigidity, and has special louvers that help increase heat transfer.The combination of internally grooved Copper-tubing and louveredfins has resulted in a heat transfer performance 30% superior tothat of a conventional coil for this particular application. Theassembly of the finned pack is achieved by mechanical expansionof the tubes in such a way as to form a perfect mechanical bondwith the fins. For this purpose, the fin holes have a peripheralextrusion (collar) of adjustable height. This extrusion serves todefine the distance between fins (and consequently the total heattransfer surface) and to ensure perfect contact of the fins to thetubes. Alternative fin materials are available upon request such asepoxy – coated aluminium or copper for applications in especiallyaggressive environments.

Water heat exchangerAll units are equipped with a Shell and Tube water direct expansiontype evaporator that has multiple cooling circuits, one for eachindependent refrigerant circuit. The casing is of steel and theinternal tubes are of copper. There is an air vent valve, drain valve,probes for water temperature sensors, differential pressure switchand the whole heat exchanger is wrapped in a heavy insulationmaterial appropriate for external installation.

Air heat exchanger fansAll unit fans are of the axial type, three phase, 6 poles, internallyprotected against potential overheating silent and suitable foroutdoor installation. Due to the sophisticated aerodynamic designof the blades and inlet cones, as well as the perfect static anddynamic balancing, their operation is completely vibration-free.The fan-motor assembly has a protective grid against accidentalcontact with moving parts, which is designed according to ISOregulations. Fan motors are aerodynamically shaped so as not tointerfere with the airflow, and have permanently lubricatedbearings that do not require servicing. Continuous linear fan speedregulation control is achieved according to coil temperaturesincluding fan silent mode operation. This is an optional feature forInterklima LPCA units that saves energy and reduces sound levelsdramatically, optimizing capacity.

1. Installation10.

The LPCA-RMB unit should be installed in a location that meetsthe following requirements:1. The foundation is strong enough to support the weight of the

unit, and the floor is flat to prevent vibration and noisegeneration.

2. The space around the unit is adequate for servicing and theminimum space air inlet and air outlet is available. If severalunits are being installed side by side in parallel, the minimumservice space between them must be taken into account.

3. There is no danger of fire due to leakage of inflammable gas.4. Ensure that water cannot cause any damage to the location in

case it drips out of the unit.5. Make sure that the air inlet and outlet of the unit are not

positioned towards the main wind direction.Frontal wind shalldisturb the operation of the unit.If necessary, use awindscreen to block the wind.

6. In heavy snowfall areas, select an installation site where snowshall not affect operation of the unit.

7. Make sure that the unit can be fixed directly on concrete.8. In order to avoid the transmission of vibration from the

operating unit to its carrying structure, the use of antivibrationmaterial to install under the supports of the unit isrecommended. It is suggested to install a rubber pad betweenthe points of support and the base of the unit, or springantivibration mounts under each point of support of the unit.

Example with one central pump

ñ All field connections must be provided by a licensedtechnician and must comply with the relevant local andnational codes.

ñ Evaporator water connections should be made in accordancewith the unit outlook respecting the water inlet – and outlet.

ñ Water piping to be arranged so that the circulating pumpdischarges directly into the evaporator.

ñ Install a flow switch or water differential pressostat (standardcomponent) in the water outlet piping to prevent the unit fromoperating at a water flow, which is too low. A terminal isprovided in the switch box for the electrical connection of theflow switch in the control circuit.

ñ To avoid erosion, it is recommended to install a filter in thewater inlet pipe.

ñ It is essential to install a thermometer in the water inlet/ outletpipe to check temperatures.

ñ Provide heat insulation with suitable vapour barrier around thechilled water piping to prevent condensation and capacity loss.

ñ Provide drain connections at all low points of the system topermit complete drainage for maintenance and/ or shutdown

ñ Air vents should be provided at all high points in the systemlocated were they are easily accessible for servicing. Thewater inlet pipe is specially designed to obtain a complete airpurge of the evaporator

ñ Install an expansion tank on the suction side of the waterpump so that the water pressure on the pump suction will bepositive.

ñ To avoid frequent on/off operation of the compressor, aminimum water volume is required in the system (table 10.4)

ñ To assure proper operation of the unit, the water flow throughthe evaporator must be within the specified in (table 10.4)
