土壤源地源热泵系统能效测试分析

摘要

Through monitoring the refrigeration data of the ground-source heat pump system for one club house in Jiangyin,the inlet & outlet water temperature and the electricity consumption of the ground-source side and the user side are obtained,so as to calculate the cooling load of the building,COP and EER.The results show that the average inlet and outlet temperature of chilled water are 8.7 ℃ and 12.5 ℃ respectively.The cooling load of the building is 33.4 kW.The average COP and EER are 4.1 and 3.1 respectively.The performance of the ground-source heat pump unit can not reach the ideal operation condition,so the optimization of the heat pump has to be done in the future.Based on the the system monitoring and efficiency analysis on the ground-source heat pump system,the operation guide,energy-saving diagnosis and system optimization can be conducted,which will promote the application of ground-source heat pump system widely and lay foundation for the purpose of energy-saving quantification in China.%对江阴地区某会所建筑土壤源地源热泵系统制冷期数据监测,获取地源侧和用户侧供、回水温度及耗电量等数据,计算得到建筑冷负荷、机组制冷系数COP和系统能效比EER.结果表明,用户侧冷冻水供、回水平均温度分别为8.7℃和12.5℃,建筑冷负荷为33.4 kW,机组COP和系统EER的平均值分别为4.1和3.1,热泵机组未能达到理想工作状态,有待进一步改进.通过对土壤源地源热泵系统的监测及节能效果分析,可以对系统运行进行指导、节能诊断和系统优化,从而更好地推广土壤源地源热泵系统的应用,为实现国家节能量化的目标奠定基础.
