Engineering Design of Solar Energy and Air
Source Heat Pump hot water system
【Abstract】On the one hand, the addition of solar energy can improve the COP of
air source heat pump, especially when the environment temperature is low. On the
other hand, the combination of heat pump with solar energy also can make up the
shortcomings of that the solar water heater can not normally operate at the rainy
weather, on the night and on the days of low solar intensity. Therefore, air source heat
pump with solar energy water system can improve the efficiency of solar collectors
and the performance of heat pump system, and resolve the issue of round-the-clock
heating at the same time. It is apparently economic and socially beneficial, and has
broad market prospects. In this paper, a set of solar energy & heat pump water heater
system was analyzed economically. Calculating results shows that solar energy & heat
pump water heater system has evident effects of energy consumption.
