摘要

将平板微热管光伏光热组件改造为新型光伏光热蒸发器，研发新型太阳能-空气双热源热泵系统，对太阳能供热模式和双热源供热模式下系统的运行性能进行研究。研究表明：受太阳辐射和环境温度影响，双热源供热模式下环境空气的作用会在放热和吸热之间转换，环境温度与背板温度的温差在-3.1~3.5℃之间波动；双热源供热模式适合在低辐照条件下运行，其热效率、综合性能效率和COP分别达56.7%、81.7%和2.38，比太阳能供热模式提升20.3%、25.0%和6.7%；在高辐射条件下，双热源供热模式会造成系统散热加快，但是对系统发电性能有提升作用。根据上述特性，当背板温度小于环境温度时启动双热源供热模式，反之启动太阳能供热模式，可以进一步提升系统的运行效果。

Abstract

The flat micro heat pipe array photovoltaic-thermal module was retrofitted into a photovoltaic-thermal evaporator

and then a novel solar energy and air dual-heat-source heat pump system was developed. The operation performance of the system operating in the solar energy mode (S) as well as the solar energy and air dual-heat-source mode (SA) was studied in detail. Studies have shown that: affected by solar radiation and ambient temperature

the role of ambient air in the dual heat source heating mode will switch between heat release and heat absorption

and the temperature difference between ambient temperature and backplane temperature fluctuates between -3.1—3.5℃; the SA mode was suitable for low solar radiation condition

and its thermal efficiency

comprehensive performance efficiency and COP were 56.7%

81.7% and 2.38 respectively

which were 20.3%

25.0% and 6.7% higher than that of the S mode; under the high solar radiation condition

the SA mode would accelerate the heat dissipation of the system

but it could improve the electrical performance of the system. According to the above characteristics

it would get the better operation performance operating in SA mode when the backplane temperature was lower than the ambient temperature as well as operating in S mode when the backplane temperature was higher than the ambient temperature.
