The Applied Prospect of Ground Source Heat Pump in China

摘要

Ground source heat pump (GSHP) is a technology that through applying earth energy as energy supplies building with air-conditioning.The paper briefly introduces working principle of the technology,the background of its development,and analyses the applied prospect of GSHP in China.China is situated on middle and low latitudes of the Northern Hemisphere.There is a transitional region (The region is hot in summer and cold in winter) in zhina,which is very suit for the application of GSHP because the days of supplying heating equal to those of supplying cooling,and the soil type and ground temperature are also suit for the application of GSHP.Moreover,the application of GHSP in China can reduce Chinese pressure of energy,improve Chinese energy structure,cut down the consumption of coal and improve the share of regenerative energy.Because there is no leak during the utilization of GSHP and GSHP can play a positive role for reducing the greenhouse effect,the application of GSHP will be beneficial to solve the problem of Chinese environmental pollution and make contribution to world's environmental protection.Now the development of GSHP in China has earned Chinese government's support,so the applied prospect is favorable.From above we can say that GSHP has an broad application in China though there may have obstructions during the applying process.
