摘　　要：太阳能-空气双热源复合热泵技术能有效解决空气源热泵室外温度低时蒸发器易结霜、系统性能降低的缺点。本文在课题组前期研究的基础上,针对一种新型的太阳能-空气双热源复合热泵系统,采用分布参数法建立了系统的数学模型。利用数学模拟的方法对单一空气源热泵系统和太阳能-空气双热源复合热泵系统在三种不同工况下的制热量和COP进行了模拟,并对模拟结果进行了对比分析。The problems such as the easily frosting of the evaporator and the poor system performance in low outdoor temperature can be effectively solved with the solar-air dual-source heat pump technology. In this paper, based on the previous working of the research group, the steady distributed parameter method has been adopted to establish the mathematical model of a new solarair dual-source heat pump system. The system performance of the single air source heat pump system and the solar-air dual- source heat pump system in three operation conditions have been studied with the mathematical simulation method, and the simulated results have been analyzed.
