摘　　要：To further improve the utilization efficiency of solar energy and the performance of solar heat pump heating systems,a new heating mode of a solar air-source heat pump（SASHP）is proposed,and the characteristics and performance of the heat pump part of this new heating system are studied.Based on a SASHP with 10 kW,the mathematical model of this system is built,and the characteristics and performance are concluded from the simulation analysis at different environmental temperatures and output water temperatures.The results show that the performance of heat pumps can be greatly improved based on the new SASHP.When the environmental temperature is 7 ℃,the coefficient of performance（COP）of the air-source heat pump（ASHP）can be increased by 26% at most.This paper sets up a base for further study on the heating system with this new SASHP in the heating season.为进一步提高太阳能利用效率和太阳能辅助空气源热泵供热系统的性能,提出了一种新型太阳能空气源热泵供热系统,并研究了该供热系统的性能和特性.基于自行设计的10kW空气源热泵,建立了供热系统的数学模型,通过模拟得出了不同环境温度和出水温度下供热系统的运行特性和性能规律.结果表明:基于新型太阳能辅助空气源热泵供热系统,热泵的性能得到较大的提高.当环境温度为7℃时,空气源热泵的COP最大可增加26%.这为进一步研究新型太阳能辅助空气源热泵供热系统在供暖季节的性能奠定了基础.
