Energy and environmental issues is currently the major issues facing the world , National Eleventh Five-Year Plan proposed the construction of village living standards improve mission also raises building energy efficiency and environmental requirements. China's current rural energy structure lag , which caused a serious waste of energy and environmental pollution problems, is highly necessary to find a cheap and abundant storage capacity of renewable energy , in order to solve the rural winter heating and summer cooling and other issues . Underground resources is a natural, non-polluting , abundant new energy. The project for the National Eleventh Five-Year Support Project \Building Design summer groundwater wells and underground pools direct cooling system and groundwater source heat pump system combined. Summer cooling load of the building or the transition season low , the direct use of underground well water as cold source ; cooling load is large open compressor cooling . Winter use of an underground well water as a heat source heat pump . Groundwater direct cooling technology with energy saving, economy, environmental protection , etc., can reduce electricity consumption and peak period demand for power , and can reduce greenhouse gases and CFC emissions. Both heating and groundwater source heat pump system combined to solve the underground temperature field of hot and cold balance, extending system life . In this thesis, the design of the system , and completed the operating conditions of the test , the system through the air volume , air temperature , water quantity, water temperature, power consumption , indoor environmental temperature and other parameters are tested to detect the room air flow and heat balance ; through the system analysis and system performance coefficient is calculated for system economy , stability , energy efficiency evaluation, and as a reference for system optimization .
