Meidibao Residential 12kw Cop4.8 Air to Water Heat Pump (DC Inverter Series)

Meidibao's DC inverter air source heat pump utilize DC inverter technology and REPM compressor which running speeds can be adjusted follow the variation of ambient or water temperature, hence to regulate the output capacity with changeably, this can heat the storage tank or room much quicker than normal on/off heat pumps, and balance the water or air temp very precisely. This also provides a very high COP as inverter system does not waste the energy. By inverter technology of frequency changeable the inverter heat pump can increase the compressor speeds to be more than 5000rpm at very low ambient at -25C. This can increase refrigerant mass flow rate to offset the source energy loss and keep an acceptable performanceMeidibao DC Inverter system can deliver 30% or more efficiency - the inverter system is more efficient than normal on/off system, the changeable output capacity and special inverter compressor which rotor uses rare earth permanent magnetic materials which does not need the second power charging, this normally can save 16% power consumption plus the advantage of variable output capacity, the total power saving can reach to 30%.
Comfortable-The traditional heat pumps always to meet the user required condition (Temperature) by Frequently switch on/off. This cause the temperature fluctuated remarkably, which normally is plus or minus 2 degrees this may make people feel uncomfortable. The inverter heat pump can balance the temperature to get 0.5C precisely. Because the inverter heat pump can regulate the compressor speeds with output capacity to meet with the actual requirement accurately.More faster- If there is a big difference between the set and actual temperature, the inverter compressor will be running at high speeds to produce more energy to heat or cool the room rapidly , when the difference has reduced, the inverter heat pump will down its running speeds to reduce the output capacity to save the power consumption and balance the desired temperature.Line-upModelM-D07ADHM-D12ADHM-D18ADHPerformance at A7/6C, W30/35C (EN14511-2 standard rating conditions)Rated Heating capacityKW7.5012.5018.50Heating capacity range (30-90Hz)KW2.25~9.003.75~15.005.55~22.20Rated COP/4.804.814.79Rated Input powerKW1.562.603.86Performance at A2/1C, W a/35C (a- the test is performed at the flow rate obtained during the test at the standard rating conditions)Rated Heating capacityKW6.5310.8816.10Heating capacity range (30-90Hz)KW1.96~7.833.26~13.054.83~19.31Rated COP/4.084.144.07Rated Input powerKW1.602.633.95Performance at A-7/-8C, W a/35C (a- the test is performed at the flow rate obtained during the test at the standard rating conditions)Rated Heating capacityKW5.228.7012.88Heating capacity range (30-90Hz)KW1.57~6.262.61~10.443.86~15.45Rated COP/3.473.563.46Rated Input powerKW1.512.453.72Parameters of main componentsCompressorQTY111TypeInverterInverterInverterUser side heat exchangerQTY111TypePlate exchangerPlate exchangerPlate exchangerSource side heat exchangerTypeTube in finTube in finTube in finFan and air flowQTY112TypeAxialAxialAxialm3/h350079009800User side circulating pump and water flowQTY111L/S0.360.600.88RefrigerantgR410A/R410A/R410A/Throttle deviceTypeEEVEEVEEVParameters of overall unitFunctions/Hot water+Room heating/cooling +Solar control (Change over automatically)Control/LCD touch panel standard/ internet, APP control alternativeDelivery waterC20-65CPower supply/230V/1P/50Hz230V/1P/50Hz380V/3P/50HzNoise leveldb(A)404447Color/Optional /default white
