摘要
对武汉部分公共建筑地埋管地源热泵系统运行参数进行测试,对系统能效水平进行评价。将传统供能系统(常规水冷冷水机组+天然气锅炉)作为比较对象,计算地埋管地源热泵系统节能率。部分项目的热泵系统制冷、制热性能未能达标,但差距不大。热泵机组供回水温差普遍偏小。项目水泵能耗水平优于全国实测水平,但少数项目水泵能耗偏高。各项目的节能率为17.0%~50.9%,平均节能率为31.0%,节能性比较好。
The operating parameters of the buried pipe ground-source heat pump system in some public buildings in Wuhan were tested,and the energy efficiency level of the system was evaluated.The traditional energy supply system(conventional water-cooled chiller+natural gas boiler)was used as the comparison object to calculate the energy saving rate of the buried pipe ground-source heat pump system.The refrigeration and heating performance of some heat pump systems in certain projects did not meet the standards,but the difference was not significant.The difference in water temperature between the supply and return of heat pump units is generally small.The energy consumption level of water pumps in the project is higher than the national measured level,but a few projects have higher energy consumption of water pumps.The energy-saving rate of each project is 17.0%-50.9%,with an average energy-saving rate of 31.0%,indicating good energy-saving performance.
