Other AbstractThis paper introduces the ground-source heat pump for a construction in Jiangyin.Using the software of TRNSYS,the underground soil average temperature in30years was simulated under the different depths and ratios of cooling and heating loads.The annual trend of COP of the system and part load ratio of heat pump unit in heating and cooling period werer analyzed.The result showed that the performance of buried pipe at100m depth had a smaller temperature drop and fluctuation than that at80m and60m depths.So the deeper the buried pipes were,the more stable of soil average temperatures were.To meet the demand of heating load only,the soil average temperature fell by2.67℃,while the soil average temperature increased by2.15℃to meet the demand of cooling load nly.If to meet the demand of both heating and cooling loads,the soil average temperature fell by just0.66℃.The averaged COP of the heat pump system was3.28in the summer and2.75in the winter;and the part load ratio of heat pump unit was low,which resulted in the lower COP of the system.The simulation results provided the basic data for the heat pump project in Yangtze River area.
