摘　　要：为了研究采取热平衡措施和没有采取热平衡措施的土壤源地源热泵空调系统经过长期运行,对地下土壤的温升影响情况,对西安市某项目土壤源地源热泵空调系统进行了模拟研究。利用TRNSYS软件建立了2个系统模型,一个模型与项目工程空调系统保持一致,采用全年制备生活热水的平衡换热量措施来抵消夏季向土壤中送入的多余热量;另一个模型没有平衡换热量的措施。通过全年和10年期的模拟运行后,采取热平衡措施的系统,其地埋管换热器周围土壤温度温升分别为0.12℃、1.14℃;没有采取热平衡措施的系统,其地埋管周围土壤温度温升分别为0.64℃、3.46℃,对土壤的影响远远大于采取了热平衡措施的系统。In order to study the temperature rise of underground soil after a long period of operation with the ground source heat pump air conditioning system,which take measures to balance the heat exchange or not,this paper makes a simulation study of ground source heat pump air conditioning system to a building in Xi'an. Two system models was established based on the TRNSYS software,one model is consistent with the air conditioning system of the project,which using the measure of preparing domestic hot water in the whole year to balance heat exchange,another model did not take measures to balance the heat exchange. Through whole year and ten years' simulation run,the system with thermal equilibrium measures,whose soil temperature around the ground heat exchanger rose 0. 12℃ and 1. 14℃; the system without thermal equilibrium measures,whose soil temperature around the ground heat exchanger rose 0. 64℃ and 3. 46℃,this system has a greater impact on the soil than the system without thermal equilibrium measures.
