介绍了一种太阳能-土壤源热泵联合供热系统,对其运行试验数据进行了分析,并对其运行能效比与两种单独由土壤源热泵供热的模式进行了比较.土壤温度的变化不仅与取热速率有关,还与地温的自动恢复能力相关.该试验建筑所在的土壤条件下地温的恢复能力为30～40MJ/d.采用太阳能.土壤源热泵联合系统能效比最高,土壤源热泵单机组双供系统次之,而土壤源热泵单机组单供系统能效比最低.太阳能跨季节储热及土壤源热泵联合供热系统适用于热负荷远大于冷负荷的建筑.

A central heating system with solar seasonal storage uniting soil source heat pump was introduced.All of the experimental data were analyzed, and the course COP were compared with two kinds of soil source heat pump.The change of soil temperature was based on the speed of extraction heat from soil, also based on the resilience of the soil temperature.The resilience of the soil temperature in thus soil condition is about 30 to 40MJ per day.The COP value of the system of solar-soil source heat pump is largest, next the soil source heat pump with one consumer, and the soil source heat pump for two consumer is least.The solar seasonal storage and soil source heat pump heating system is applicative to the buildings, whose heating load is far larger than cooling load.
