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 ...
It was found that the water heating capacity increased significantly, together with a lower rate of power consumption increase, which led to an increase of the overall COP. The hot water also greatly reduced the defrosting time. Fan et al. (2008) tested a heat pump water heater using R22 ...
JNOD All In One heat pump water heater is one of the most economical water heating systems to provide domestic sanitary hot water for the house. It could be put indoor. It is with 3~4 times higher efficiency than gas boiler or electrical h...
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 80 deg C. * Copeland compressor & R134a refrigerant; * Stainless steel 304 for all fastener...
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 ...
