Based On TRNSYS Ground Source Heat Pump System Simulation And Experimental Research In Hot Summer And Cold Winter Region

This paper takes a ground source heat pump project in hot summer and cold winter region for example.Combined with the building model,HAVE model and GHSP model of TRNSYS software,building the ground source heat pump system model.And take the test date to study and simulated the ground source heat pump system.The main research contents are as follows:(1)Combined with the project,built the building hourly load model and ground source heat pump system model,providing a good platform for late simulation.(2)Compare with simulated date and test date,analyzed the veracity of the model and the performance of system,and show the efficient and stable of system.(3)Analyzed the performance of underground heat balance by TRNSYS with the project.The result show that the thermal unbalance rate is 11.9%and the soil average temperature will rise 0.5 ? in ten years,And soil average rose the most in the previous five years,five years after the soil temperature is almost the same.(3)According to the characteristics of the air conditioning energy consumption in the area with hot summer and warm winter,summer energy consumption under different indoor temperature is studied,when indoor setting temperature rises from 25 to 26,air conditioning energy consumption reduced by 10%,when indoor setting temperature rises from 25 to 27,air conditioning energy consumption reduced by 8%...
