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 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 4 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. 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 introduced in 1998 in Shenyang, the relatively early with Tokyo Electric Power dormitory, Shenyang Institute of Automation, Liaoning Science and Technology Building, Medical School sophomore, etc., heating and cooling large area of 100,000 m2 or more, only a small 2020m2. Typical is the Shenyang Institute of Automation of the construction area by million m2, 1999 the introduction of water source heat pump central air conditioning system to replace the existing two coalfired boilers. 2020, 152 days in winter heating, summer cooling 100 days. Annual operating cost of yuan / m2. Heating and cooling cost savings throughout the year 7 million. Shenyang City in recent years by examining the construction and operation of water source heat pumps as far as the introduction of the heat pump units are relatively molding technology, in terms of operating efficiency and maintenance requirements are able to reach. But as a heat pump system is a key ponent of the well group, the recharge process and as well there are still many 5 problems, mainly in the following areas: First, in the design of pumping and injection wells spaced ground source heat pump is usually the manufacturer with reference to the experience of value, ignoring the different geomorphological units hydrogeological factors, design of well spacing is too large, for highdensity residential district or city mercial construction applications deep recharge water source heat pump system, because the availability of building land area restrictions, well group can not be arranged, seriously affecting the water source heat pump system in promoting the use of Shenyang. Such as medical sophomore distance between water source heat pump wells is too large, the number of rechar
