Low-carbon Technology Application in Wuhan Based on Ground Source Heat Pump System

Abstract

It is known that ground source heat pump system (GSHPS) takes the advantage of shallow geothermal energy which include the power of underground water, surface water or soil etc., and the system can not only provide heat apply but also provide cold making power in a high efficiency and energy saving way. The ground source heat pump only uses the shallow geothermal resources of the earth's surface (usually less than 400 meters deep) as cold and heat source, it takes less effect on earth and its environment. The GSHPS could replace air-conditioner heater and domestic hot water facilities. The running process of GSHPS is green without any pollution. It can be built in a residential area, no burning, no smoke, no waste, no stacking fuel waste sites, and no long-distance transport of heat. The system does not consume water or pollute water, no boiler, no cooling towers, does not need stacked fuel waste sites. It leads significant environmental benefits. With the experimental application in the project in Wuhan, it showed the advantages of GSHPS, the using feasibility of GSHPS and also the disadvantages and limitations of GSHPS. And with the developing of the GSHPS technology, the use of the system can have a considerable prospect.
