摘　　要：土壤蓄热式空气源热泵系统是利用风水换热器将土壤区域换热器和空气源热泵系统进行复合,共同为建筑提供供冷(热)需求。通过Trnsys模拟软件对该系统在某办公建筑内的应用结果进行模拟分析,发现增加土壤蓄热部分后,空气源热泵系统在供暖季最冷天的制热COP值为2.29,制热效果满足建筑供热需求,空气源热泵的供暖稳定性增强、制热能效比较高。土壤蓄热模块的加入决定了用户侧的供水温度以及空气源热泵的能效水平,系统更高效节能。The soil thermal storage air source heat pump system utilizes a wind water heat exchanger to composite the soil area heat exchanger with the air source heat pump system,jointly providing cooling(heating)needs for the building.Through the simulation analysis of the application results of the system in a certain office building using Trnsys simulation software,it was found that after adding soil heat storage,the COP value of the air source heat pump system in the coldest day of the heating season was 2.29,which met the heating needs of the building.The heating stability of the air source heat pump was enhanced,and the heating energy efficiency was relatively high.The addition of the soil heat storage module determines the water supply temperature on the user side and the energy efficiency level of the air source heat pump,making the system more efficient and energy-saving.
