摘　　要：土壤热失衡问题会导致热泵性能下降.为解决这一问题,以大庆市某办公建筑为例,利用瞬态系统模拟软件TRNSYS对跨季节蓄热型太阳能-地源热泵系统进行采暖及制冷10年的数值模拟.结果表明:太阳能-地源热泵系统其土壤初始温度降为4.50℃,而跨季节蓄热型太阳能-地源热泵系统的土壤温度升到6.63℃.同时,太阳能-地源热泵系统的热泵平均COP为3.2,跨季节蓄热型太阳能-地源热泵系统的热泵平均COP为3.28,同比上涨2.5%.此时总耗电量减少4.44%,全年运行费用降低了5.54%,费用年值减少了1 257.69元.由此可见,跨季节蓄热型太阳能-地源热泵系统不仅可以有效缓解土壤热失衡问题,还能提高寒区地源热泵的性能并且减少能耗,经济性能好.Soil heat imbalance can result in reduced heat pump performance.To address this issue,an office building in Daqing City utilized the transient system simulation software TRNSYS to model the heating performance of a heat storage solar-ground source heat pump system.The results revealed that over a ten-year simulation period,the soil temperature in the solar-ground source heat pump system decreased from the initial level to 4.50℃,whereas the soil temperature in the heat storage solar-ground source heat pump system increased to 6.63℃across seasons.Additionally,the average COP of the heat pump in the solar-ground source heat pump system is 3.2,while the average COP of the heat pump in the heat storage solar-ground source heat pump system increases to 3.28 across seasons,representing a year-on-year increase of 2.5%.During this period,total power consumption decreased by 4.44%,annual operating costs were reduced by 5.54%,and annual cost savings amounted to 1257.69 yuan.This demonstrates that the cross-season heat storage solar-ground source heat pump system not only effectively mitigates soil heat imbalance but also enhances ground source heat pump performance,reduces energy consumption,and offers better economic benefits.
