1. Technical DescriptionGeneralThe SPCA-HSB series air-cooled water heat pump consists of 9models covering cooling capacities from 5,8 up to 31,8kW andheating capacities from 6,9kW up to 37,3kW.It is the end result of a thorough study, and accurate design byexperienced Interklima research and development teams, todevelop a small size heat pump 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. SPCA-HSB 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. After fabricationmetal parts are degreased, phosphatised, and electrostaticallypowder coated with an epoxy-polyester RAL 9002 coating of athickness of 60-70 Ì. This fully automatic process ensuressuperior corrosion resistance against the most aggressive ambientconditions. The treatment can successfully withstand a salt spraytest of 500 hours, according to ASTM B-117.All components are assembled together using bolts thus avoidingthe need for welding which may harm the galvanization of thesteel, and ensures that the whole assembly can fully withstandadverse 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 panels with special locks are used to permit accessonly to authorized personnel to internal components of the unit forinspection and maintenance.CompressorAll units use low-noise, maintenance free, Hermetic Scrollcompressor 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,and are internally protected against potential overloading orelectrical spikes.The compressors are mounted on special antivibration rubbermounts to eliminate vibration from the unit’s operation.Hydraulic kitAll units are equipped, as standard, with a complete hydraulic kitcomprising of a circulating pump, buffer and expansion tank,automatic fill and make up water valve with manometer, safetyvalve, airvent, water filter, differential water pressure switch, andevacuation valve.Air heat exchangerAll unit air heat exchangers are manufactured from high qualityinner grooved seamless copper 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 have 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 as epoxy- coated aluminium or copper for applications in especiallyaggressive environments.Water heat exchangerAll units are equiped with a water - refrigerant Plate HeatExchanger, selected from world class manufacturers.It is made of stainless steel plates (AISI 3161.4401) speciallyformed to achieved a large heat transfer surface and assembledby means of an automatic brazing proccess, under vaccum.Air heat exchanger fansAll unit fans are of the axial type, single 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. Thefan-motor assembly has a protective grid against accidentalcontact with moving parts, which is designed according to ISOregulations. Fan motors are of the external rotor type,aerodynamically shaped so as not to interfere with the airflow, and4Interklima Hydronic systemsSPCA 001-010HSB ñ R407c/Scroll

have permanently lubricated bearings that do not require servicing.Continuous linear fan speed regulation control is achievedaccording to coil temperatures including fan silent mode operation.This standard feature for Interklima SPCA units saves energy andreduces sound levels dramatically, optimizing capacity.Microprocessor controllerAll units are equipped with a sophisticated controller easilyaccessible from outside through a transparent plastic cover thatcombines intelligence with operating simplicity.
