The Experimental Study on Heat Balance and Soil Temperature Distribution of Ground Source Heat Pump of Air-Conditioning System

This paper uses operating results of the whole year of the ground source heat pump of air-conditioning system,and studies the heat transfer between the ground heat exchanger with the surrounding soil.At the same time,the paper studies the temperature distribution of the heat exchanger's surrounding soil.The experimental and theoretical results show that as the system utilizes the heat recovery technology,the system reduces about 33.7%heat which discharges to the ground. After the system operates one year continuously,the average temperature of the soil rises 0.7℃. The technology has solved the problem of the soil heat balance in the hot summer and cold winter zone.
