ump in winter than air water heat pump high, and there is no condensation and other issues. Summer Zeyi 12 ~ 26 ℃ cooling water for the refrigerator, can be very high COP, and even in some cases, this water can be directly used for air conditioning for cooling instead of open water source heat pump. Because groundwater heat transfer through the heat exchanger 3, the rear back underground, only the use of groundwater cooling (heat), without consuming a drop of water resources, groundwater is not in contact with air the entire process, and therefore will not cause groundwater resources pollution. Second, the water source heat pump central air conditioning technology developments at home and abroad Water source heat pump technology (hereinafter referred to as GWHP) The proposal began in Britain and the United States, the United States 30 years from the 20th century began to apply. Oregon in 1948, an engineer Krocker created a water source heat pump applications in mercial buildings. 50 years of the 20th century occurred in Europe for the first time using GWHP climax. At that time, lower energy prices, lack of economic petitiveness of such systems, but have not been promoted. With the last decade, especially in the last five years, energy price increases, GWHP in North America such as USA, Canada and the Nordic such as Switzerland, Sweden and other countries have made rapid development, according to 1999 statistics, the household heating device, GSHPs proportion of 96% in Switzerland, Austria, 38%,27% in Denmark. China Back in the 39。 50s, once in Shanghai, Tianjin and other places try to take winter irrigation way summer of extraction of groundwater cooling, Tianjin University, Institute Professor Lv Canren energy has carried out the earliest studies of heat 1965, successfully developed China39。 s first watercooled heat pump air conditioners. At present, Tsinghua University, Tianjin University, Chongqing University, Tianjin, Shandong Institute of Technology built, the CAS Guangzhou Institute of Energy and many other universities and research institutions in the study of water source heat pump. Tsinghua University, which after years of working conditions in a 137 multisource heat pump industry has formed the research results of several demonstration projects have been pleted. Can be expected that the technology will be most effective in the 21st century heating and cooling air conditioning technology. Third, the water source heat pump technology in the region to promote the superiority of Shenyang 1, hydrogeological conditions are suitable Water is a prerequisite for application of water source heat pump, water system, water, water temperature, water quality and water source heat pump system stability is a run effects of important factors. Shenyang is located in the city on the Hun River Alluvial Plain aquifer is mainly coarse sand, gravel and pebbles, abundant groundwater resources, with the protection of groundwater resources in recent years intensified, with factories migrate to the suburbs, Shenyang underground funnel area has been basically eliminated. Now, the groundwater level between the 5060m, depth 513m. Summer and winter water temperature maintained at a constant 12 ℃ , PH value of between , groundwater quality, water resources assessment in the country was excellent. Shenyang City this unique hydrological and geological conditions is unique in the country to meet the water source heat pump system is running on the water, adequate water, moderate temperature, the water is suitable, stable water supply requirements, water source heat pump system for largescale promotion in Shenyang . 2, the water source heat pump technology in the construction field advantage in the application As a new water source heat pump heating and cooling technology, more and more attention at home and abroad, and its advantages in the construction field in the following areas: ① lower energy consumption. The biggest advantage of ground source heat pump heating and cooling with conventional air conditioning systems consume less power pared. Under the proper conditions of air heat pump system than the 40% energy savings pared to electric heating energy saving over 70%. ② to improve the building appearance. Since there is no outdoor pressors or cooling towers, so the possibility of damage greatly reduced the appearance of the building or eliminated. ③ low environmental impact. Comparison of CO2 emissions from coalfired boilers and electric drive with the same fuel amount of CO2 emissions can be reduced by 30% 50%, in environmental protection will play a significant role. 138 ④ area are few. Compared with coalfired boiler house, the area can be reduced by half or more, If heat pump into the ground, the floor space is not occupied. Fourth, water source heat pump technology applications in the Shenyang region and the problems Water source heat pump technology is i。
