Energy Efficiency Testing and Analysis of Buried Pipe Ground-source Heat Pump System in Wuhan
The operating parameters of the bur-ied pipe ground-source heat pump system in some pub-lic buildings in Wuhan were tested,and the energy effi-ciency level of the system was evaluated.The tradition-al energy supply system(conventional water-cooled chiller+natural gas boiler)was used as the compari-son object to calculate the energy saving rate of the buried pipe ground-source heat pump system.The re-frigeration 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 con-sumption 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％,indica-ting good energy-saving performance.
