European Air To Water Heat Pump
Summary
The purpose of the project was to build a low energy and low cost
prefabricated house without compromising the comfort. Due to the
overall reduced energy consumption in low energy houses the proportion
of the heat required for DHW increases from 30% to 40%. This sets new
requirements for a heating system. In this residence there are two air to water heat pumps: one for heating (from October to April) and the other for DHW (DHW; all year round).
The former uses outdoor air and the latter indoor exhaust air as its heat source. The SPF of the 4.6 kW heat pump for space heating is 3.0. If auxiliaries such as fans for heat recovery and standby losses of the water heater are considered as well the SPF drops to 2.0.
China Palm are mainly researching and manufacturing heat pump energy-saving products and commercial air conditioners
