摘要

针对光伏发电效率较低和空气源热泵在寒冷地区应用中存在的问题，研发了一种新型复合蒸发器，将平板微热管阵列太阳能光伏光热（PV/T）集热器与空气源热泵相结合，组成新型太阳能-空气复合热源热泵热水系统。并对该热水系统在不同运行工况下的水箱水温、吸排气压力、压缩机功率和性能等进行了实验研究。实验结果表明，在环境温度分别为5、10和15℃的条件下，热泵加热73 L水，水温从15℃加热到50℃时，双热源运行工况的加热时间比单空气热源运行工况依次缩短了5.14%、10.29%和11.38%， COP依次提高了5.99%、9.28%和11.96%。

Abstract

In the light of low efficiency of photovoltaic power generation and the problems of air source heat pump applied in cold regions

a composite heat exchanger evaporator is developed and a new type of solar-air composite heat source heat pump hot water system is designed in this study

which is comprised of independent solar photovoltaic-thermal collector based on flat plate micro heat pipe and air source heat pump. The performance of heat pump hot water system is evaluated experimentally under different operating conditions

including water temperature of the tank

heating time of hot water

suction and discharge pressure

consumption of compressor power and heat pump coefficient of performance (COP)

etc. Experimental results show that at ambient temperature of 5℃

10℃ and 15℃

with 73 L hot water heated by heat pump and water temperature in the tank ranged from 15℃ to 50℃

the running time of composite heat source operation is shorter than that of separate air heat source operation

decreased by 5.14%

10.29% and 11.38%

respectively. COPs are increased by 5.99%

9.28% and 11.96%

respectively.
