摘　　要：联合太阳能热泵与土壤跨季节蓄能技术,提出并设计建立了太阳能跨季节蓄能热泵这一新型的太阳能供暖系统。经过6个月的实验研究,得出以下结论:采用地下蓄热体对太阳能跨季节蓄能,可以解决非采暖季太阳能系统集热器过热的问题,有助于提高系统运行的可靠性;采用以黏土与粉土为主要介质的地下蓄热体蓄热,使用热泵机组提取跨季节储热时,取热率可达23%;在供暖阶段,实验测得热泵机组与供暖系统的性能系数分别为3.28与2.15。一个周期的实验表明这一太阳能供暖技术方案具有可行性。Combined solar assisted heat pump and seasonal underground energy storage technology, a novel solar heating system was proposed and built.This paper introduced six month＇s experimental study,and the experimental results showed that using duct heat store for seasonal solar energy store could solve solar collector overheating problems in non-heating period,which improved operation reliability of solar heating systems.Heat recovery efficiency reached 23%with clay and silty soil as storage material,when one heat pump was used to extract seasonal heat storage.In heating period, coefficient of performance of the heat pump unit and overall heating system were 3.28 and 2.15 respectively.The cycle experimental result showed the designed solar heating system was feasible.
