In a heat-pump water heater (1), a control unit (5) has heat-radiation determining means (S20, S21, S22) for determining a heat radiation from refrigerant to outside air in an air heat exchanger (9) based on a water temperature flowing into a water heat exchanger (7), and the ...
Wu et al. [63] constructed and tested a cascade air-source heat-pump water heater with thermal storage system (Fig. 5). Dynamic performance of the heat-pump water heater in single stage mode and cascade mode was compared and discussed. Based on the transient heating COP values, critical ...

Looking for a water heater for home use that is sustainable and environmentally friendly? Solar water heaters are your best bet. They use solar thermal collectors to convert renewable solar energy into heat and provide you with hot water. ...
High temperature air to water heat pump water heater, with Copeland compressor and R134a refrigerant, lowest working temperature can reach -15 deg C, max. water output temperature 60 deg C/80 deg C. * R410a refrigerant for HotSping series & R134a refrigerant...
Water Heater Compound with Ground Source Heat Pump GSHP (ground source heat pump) is a kind of energy saving and Environmentally Friendly technology. One of the most common problems of GSHP system is the imbalance of heat extracted from ground during space heating and heat emitted into t......
heating element, but with a small amount of electric driving the main unit's compressor to work, the low temperature air is compressed to high temperature air, through the pipeline circulation system to heat the water, the power consumption is only 1/4 of the traditional electric water h...
Why the air source heat pump is the most energy saving water heater? Air source heat pump is not direct heating by the heating element, but with a small amount of electric driving the main unit's compressor to work, the low temperature air is compressed to high temperature ...
