浅层岩土蓄能加浅层地温能才是地源热泵可持续利用的低温热源
Shallow rock and soil energy storage combined with shallow geothermal energy—sustainable low temperature source of ground source heat pumps
摘要:
当前对地源热泵低温热源的认识存在分歧,并有将浅层地能资源化的趋势。通过对土壤源热泵低温热源认识过程的回顾,结合我国地源热泵发展的实际情况,提出了浅层岩土蓄能加浅层地温能才是地源热泵可持续利用低温热源的观点。认为应基于浅层岩土层储能的思路去研究和发展地源热泵。根据冬季供热的需要和当地的地质构造决定夏季的蓄热量,并采用先进技术保证热能蓄存。
Abstract:
There are divergences in the understanding of the low temperature heat source for the ground source heat pump system (GSHP), and resource utilization of the shallow geothermal energy is becoming a trend. Reviews the recognition process of the low temperature heat source of GSHP, combined with the actual development situation of GSHP in China, puts forward that the shallow rock and soil energy storage combined with the shallow geothermal energy would be the sustainable low temperature source for GSHP. The research and development of GSHP should be in the framework of the shallow rock and soil energy storage. The quantity of heat storage in summer should be decided according to the demand of heat supply in winter and the local geologic structure. Moreover, advanced techniques should be used to ensure heat storage.
