摘要
针对重庆市某医疗建筑实际案例,以保证系统安全性、稳定性、运行能效及土壤热平衡为目的,对复合式地源热泵系统的设计方案与运行策略进行了分析总结。经过校核,若应用此设计方案与运行策略,此工程冬夏季土壤热不平衡率为9.42%,满足热平衡要求。并对实测数据进行分析,结果表明系统在冬季的平均能效比为3.64、夏季平均能效比3.94,保持了较高的运行效率。
Aiming at the actual case of a medical building in Chongqing,in order to ensure the system safety,stability,operating efficiency and soil heat balance,the design scheme and operation strategy of composite ground source heat pump system are analyzed and summarized.After checking,if this engineering can use the design scheme and operation strategy,the soil thermal imbalance rate in winter and summer of this project is 9.42%,which meets the requirements of thermal balance.The analysis of measured data show that the average energy efficiency ratio of the system is 3.64 in winter and 3.94 in summer,maintaining a high operating efficiency.
