太阳能与地埋管热泵联合采暖实验

Experiment on the Solar Energy and Buried Pipe Heat Pump Joint Heating

为了考察太阳能光热系统的蓄热能力,以及太阳能地埋管热泵联合采暖空调是否满足建筑物能量供给,针对一栋220 m2的建筑物,建立了一套太阳能地埋管热泵联合采暖空调系统.以冬季采暖负荷作为建筑物的能量需求,在此基础上配置太阳能和地埋管系统.实验结果表明:通过太阳能光热跨季节采暖蓄热,可以使土壤温度提高3℃,制热机组能力提高8%,太阳能光热和地埋管热泵系统联合采暖切实可行.

The authors had researched the heat accumulation capacity of solar energy system and the heating capacity of the solar-ground source heat pump system. The solar-ground source heat pump system was built for 220 square meters of the building. Considering winter heating load as building energy demand, we built the solar-ground source heat pump system. The experimental results suggest that, the soil temperature has been raised 3 ℃ , and the heating capacity of heating system has been improved by 8% , it is feasible to use this system in heating seasons.
