Extremely Cold Winter Use 18.8 Kw Inverter Heat Pump

Product Description R410a EVI DC Inverter Heat Pump For Heating Cooling & Hot WaterInverter heat pump reduce cycling to keep your family more comfortable and to eliminate cold drafts.By minimzing energy lost during cycling,they also improve your home's overall energy efficiency and reduce energy consumption.This not only helps keep your heating and cooling bills in check but also protects the environment from the effects of air pollution and greenhouse gas emissions.  Get Class A++ energy label based on EN14825 standard.  Smart LCD Controller or Wifi Control for option,learn to operate in 2 minutes     ADVANTAGES  * Get Class A++ energy label based on EN14825 standard.* DC Inverter compressor allows optimum adjustment to actual requirements for heating or cooling.* Low operating expenses resulting from a high COP according to the EN14825 standard, ranging from 4.0 to 4.7 (A7/W35).* Maximum heating water temperature of up to 60 °C allows installation of the heat pump in systems with radiator heating.* Advanced regulation unit allows connection to solar panels and use of heat generated by them.* Excellent comfort owing to reversible performance for both heating and cooling.* The heat pump operates in the temperature range from -30 °C to +43 °C, which means that it will keep your home warm during freezing winter and effi ciently cool it on hot summer days.* R410A is among the most environmentally friendly refrigerant gases which is not detrimental to the ozone layer.* Low investment costs owing to simple installation* Optional connection to an existing domestic hot water storage tank if an internal heat transmitter is provided in suchheater. Energy-efficient domestic hot water heating - the compressor decreases the operating frequency to an optimum calculated by the control unit according to the use and the set hot water temperature.*Low noise owing to the axial fan and compressor unit with variable operating frequency.  Super Efficient and Silent by 4-core Full Inverter TechnologPower World EVI+DC Inverter heat pump adopts step-less inverter compressor,step-less inverter control system and brush-less fan motor and DC speed water pump. It can not only provide amazing energy saving,but also be as silent as a fridge, 12dB (A) lower than traditional On/Off heat pump.  Superior Heating Ability  Thanks for Power World unique EVI+DC Inverter Technology which can control well the frequency and EEV according to the ambient temperature and water temperature and the refrigerant volume of major loop of refrigerant system,even when ambient temperature is under-15°C,heat pump can still maintain same rated good heating capacity output without any auxiliary electric heater.  50%Speed up Heating TimeOnce the heat pump is on, Power World Inverter unit can quickly pick and choose the best compressor and fan motor operating frequencies and the heat pump EEV opening automatically according to the heating or cooling demand by smart inverter control technology for the first time heating,inverter fast heating can save 50%heating time than traditional heat pump.  Quick Enter to Stable StatusThe heat pump utilizes smart defrosting by controlling the frequency and EEV technology to enter the best defrosting status quickly,reduce the defrosting times and extend the effective heating time,fast recovery of water-supply temperature,improve heat pump heating efficiency and keep comfortable temperature.     Product Parameters Product model PF-030DC/E PF-050DC/E PF-050DC/NE Cooling Cooling capacity(kW) 7.7 12.8 12.8 Cooling capacity Min / Max(kW) 4.9/8.9 8.2/14.8 8.2/14.8 Cooling input power(kW) 2.6 4.2 4.2 Cooling input power Min / Max (kW) 1.5/3.7 2.5/6.0 2.5/6.0 Rated current (A) 12.7 20.5 8.4 Current Min / Max (A) 7.3/18.1 12.2/29.3 5.0/12.0 EER 2.96 3.05 3.05 EER Min / Max 2.41/3.27 2.47/3.28 2.47/3.28 Heating Heating capacity(kW) 11.8 18.8 18.8 Heating capacity Min / Max (kW) 7.4/15.9 11.7/23.5 11.7/23.5 Heating input power(kW) 2.64 4.2 4.2 Heating input power Min / Max (kW) 1.5/3.9 2.4/6.4 2.4/6.4 Rated current (A) 12.8 21 8.4 Current Min / Max (A) 7.5/19.3 11.7/30.5 4.8/12.8 COP 4.47 4.48 4.48 COP Min / Max 3.69/4.9 3.67/4.88 3.67/4.88 DHW Heating capacity(kW) 9.5 15.4 15.4 Heating capacity Min / Max (kW) 5.9/12.8 9.4/19.8 9.4/19.8 Heating input power(kW) 2.7 4.4 4.4 Heating input power Min / Max (kW) 1.5/4.2 2.4/6.8 2.4/6.8 Rated current (A) 13 22 8.8 Current Min / Max (A) 7.3/19.7 12.1/32.8 4.8/13.6 COP 3.52 3.50 3.50 COP Min / Max 3.05/3.93 2.91/3.92 2.91/3.92 Refrigerant R410A Power supply 208~240V~/50Hz 380~415V/3N~/50Hz Working area -30~43ºC Water circulation (m³/H) 2.03 3.23 3.23 Water pressure drop (kPa) 25 30 30 IP Grade (Level of protection) IPX4 IPX4 IPX4 Anti-electric shock Rate I I I Noise (dB(A)) ≤53 ≤58 ≤58 Net weight/Gross weight(kg) 140/150 170/180 170/180 Diameter of pipe (mm) DN25
