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.

manufacturing heat pump energy-saving products and
commercial air conditioners
