摘要
地源热泵被认为是一种杰出的供热(制冷)系统,其在节能与环保方面具有极大潜能。为了进一步提高该系统的节能与环保优势,将可再生能源的太阳能耦合到地源热泵组成多源热泵系统进行了实验研究,主要分析其供热特性以及对环境(主要是土壤温度场)的影响,研究表明系统供热性能系数在2.45-4.71之间,太阳能作为辅助热源对于提高其性能系数及缓解土壤温度下降起到有效作用,对土壤温度的监测表明供暖结束土壤温度6天内能够基本恢复。
Geothermal heat pump is considered to be an outstanding heating （cooling） system,and its energy-saving and environmental protection has great potential.In order to further improve the system＇s energy-saving and environmental advantages,this article has investigated the multi-source heat pump system constituted by solar energy and geothermal heat pump.The analysis of heating characteristics and environmental effects （mainly in soil temperature field） for this system were done.The results show that heating coefficient of performance （COP） of this system can keep between 2.45～4.71.And the solar energy can play an effective role in preventing the soil temperature decreasing and improving the COP of the whole system.It is shown that the temperature recovery of the soil around borehole heat exchangers need about 6 days.
