R134A Ground Source Heat Pump

Ground Source Heat Pump
- Gas type R134a-Capacity from 127 kW to 2450 kW.- Reusable: using solar energy stored in earth as cooling & heating source.- Great environmental and economic benefit: no boiler or cooling tower; less space, less CO2 and less initial investment.- Acting as multi-function unit such as cooling, heating, sanitary hot water separately or simultaneously.- Wide application as hotel, apartment, villa, factory, shopping center, office building, school, etc.- Semi-hermetic screw compressor for mod.130 - 2500. Each compressor is equipped with a crankcase heater and a thermal overload cut-out; the screw compressor is also complete with a built-in electronic protection with temperature sensor located directly in the motor winding and on the discharge line.- The refrigerant circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, direct expansion valve, high and low pressure switch.- Shell and tube dry expansion type condenser, factory insulated with flexible close cell material.- Shell and tube type evaporator, factory insulated with flexible close cell material.- The electric panel consists of compressor breaker, compressor contactor, phase sequence relay, control circuit breaker, microprocessor control with function display.- LCD display, touch screen control panel.- Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.- For the units with semi-hermetic screw compressor, an infinitely variable capacity control system that is capable of exactly matching the demand requirement of the system is to be supplied. This system is to provide precise and stable control of supply water temperature over the complete range of operating conditions.ModelTWWH-130L170L200L240L260L280L310L360L380L420LCooling capacity*kW130170200240260280310360380420Heating capacity*kW127167196235255274304353372412Power supply380-415V/3Ph/50HzCompressorQty/refrigerant circuitNr.1/11/11/11/11/11/11/11/11/11/1Cooling power input*kW24313744485257677078Heating power input*kW435666808693103120126140Energy adjustment stepsstep25% - 100%Max. current for wiringA87108128165165165165185185258Refrigerant chargekg23303643465055646875EvaporatorWater side pressure dropkPa42454545454646464746Pipe sizemmDN65DN80DN100DN100DN100DN100DN100DN125DN125DN125Water flow rate in cooling*m3/h22293441454853626572Water flow rate in heating*m3/h9121417181922252629CondenserWater side pressure dropkPa42454444454544444442Pipe sizemmDN80DN80DN100DN100DN100DN100DN100DN125DN125DN125Water flow rate in cooling*m3/h12161922242629333539Water flow rate in heating*m3/h22293440444752616471DimensionsLengthmm2635276027402880287028702970317032803280Widthmm1090111511751125112511251230120012851285Heightmm1625155516501645168516851685168518051805Net weightkg1600180019002000210022002250240030003100Noise level**dB(A)68696970707273737373ModelTWWH-480L530L610L680L710L760L860L960L1000L1120LCooling capacity*kW48053061068071076086096010001120Heating capacity*kW4705195986666967458439419801098Power supply380-415V/3Ph/50HzCompressorQty/refrigerant circuitNr.1/11/11/11/12/22/22/22/22/22/2Cooling power input*kW8998113126131141159178185207Heating power input*kW159176203226236252286319332372Energy adjustment stepsstep25% - 100% 12.5% - 100%Max. current for wiringA3023023573782x1852x1852x2582x2582x3022x302Refrigerant chargekg8594108121126135153171178199EvaporatorWater side pressure dropkPa46464647474647464646Pipe sizemmDN125DN125DN125DN150DN150DN150DN150DN200DN200DN200Water flow rate in cooling*m3/h8391105117122131148165172193Water flow rate in heating*m3/h33374247495360677078CondenserWater side pressure dropkPa42424442444244424444Pipe sizemmDN125DN125DN125DN150DN125DN125DN125DN125DN125DN150Water flow rate in cooling*m3/h444957636670808993104Water flow rate in heating*m3/h8189103115120128145162169189DimensionsLengthmm3505350535053520400545054505450545604560Widthmm1280131513751380141514151415141514601460Heightmm1970199019801980197520002000200020902090Net weightkg3500380040004100421044004740560066006800Noise level**dB(A)74747473747474747474ModelTWWH-1200L1250L1360L1470L1720L1840L2000L2350L2500LCooling capacity*kW120012501360147017201840200023502500Heating capacity*kW117612251333144116861803196023032450Power supply380-415V/3Ph/50HzCompressorQty/refrigerant circuitNr.2/22/22/24/44/44/44/44/44/4Cooling power input*kW222231252272319341370435463Heating power input*kW399415452488571611664781831Energy adjustment stepsstep12.5% - 100%6.25% - 100%Max. current for wiringA2x3572x3572x3784x1854x2584x2584x3024x3574x357Refrigerant chargekg213222242261306327356418444EvaporatorWater side pressure dropkPa464646454546464747Pipe sizemmDN200DN200DN2002xDN1502xDN1502xDN2002xDN2002xDN2002xDN200Water flow rate in cooling*m3/h206215234253296316344404430Water flow rate in heating*m3/h848795102120128139164174CondenserWater side pressure dropkPa444245525252525252Pipe sizemmDN150DN150DN1502xDN2002xDN2002xDN2002xDN2002xDN2002xDN200Water flow rate in cooling*m3/h111116126136159170185218232Water flow rate in heating*m3/h202211229248290310337396421DimensionsLengthmm466046604660460046504690473047804800Widthmm158515851585225022702300234023802400Heightmm221522152240235023802410245024702500Net weightkg700074008000880090009800116001230013000Noise level**dB(A)747476808081818282* Performance values refer to the following conditions:Cooling: condenser water inlet/outlet temperature: 18ºC/29ºC, evaporator water inlet/outlet temperature: 12ºC/7ºC.Heating: condenser water inlet/outlet temperature: 40ºC/45ºC, evaporator water inlet/outlet temperature: 15ºC/7ºC.** Noise level measured in free field condition at distance of 1 meter.
