EXPERIMENTAL STUDY ON SOLAR AND AIR SOURCE HEAT PUMP INTEGRATED SYSTEM WITH TRIPLE-SLEEVE ENERGY STORAGE EXCHANGERS

分析了三套管蓄能型太阳能和空气源热泵集成系统的特点,并建立了实验台来验证这一新型系统的可行性。实验台主要对系统的关键部件,三套管蓄能换热器的蓄、释能特性进行了研究。实验数据表明系统在直膨蓄冷模式时COP可达2.0～2.8,在蓄能供热模式时COP可达3.00～3.75,同时蓄释的供热模式时系统COP可达3.31～3.45,实验结果证明三套管蓄能型太阳能和空气源热泵集成系统是可行的,可以在多种模式下高效、安全运行。

An experimental table was built to verify the feasibility of solar and air source heat pump integrated system with triple-sleeve energy storage exchangers based on the characteristics analysis of it in this paper. Experimental data show that the COP of integrated system is between 2.0 and 2.8 in direct expansion cold storage mode, between 3.00 and 3.75 in heating mode using heat storage, between 3.31 and 3.45 in heat and release mode. So the feasibility of the integrated system is proved by the experiment results, the new integrated system can work efficiently and safely in different modes.
