摘要
本文提出了一种适合严寒地区供暖的太阳能热泵系统,介绍了系统的原理、运行模式及控制措施。多种运行模式使系统在不同工况下具有较好的适应性,可最大程度利用太阳能,保证热泵的运行效率。大庆某实际工程的运行数据表明:12月典型日集热器集热效率为51%;若采用夜晚值班供暖,11月典型日太阳能保证率可达70%。单位供暖面积供暖费用为18元左右,可节约60%,系统具有较好的节能性和经济性。
In this paper,a solar assisted heat pump system for heating in severe cold zone was proposed,and its principle,operational modes and control measures were introduced.This system had good adaptability under different operation conditions with several operational modes,the solar energy could be utilized to the greatest extent and the operational efficiency could be guaranteed.The operation measurement results of a practical engineering in Daqing indicated that the thermal efficiency of solar collector was 51% of the typical day in December.If employing standby heating in the night,the solar fraction would up to 70% of the typical day in November.In addition,the cost of per heating area was about 18 RMB,saving by 60%.To sum up,the system had good performance of energy conservation and economical efficiency.
