河南城建学院本科毕业设计（论文） 摘要

摘要

随着经济的发展和人们生活水平的提高，公共建筑和住宅的供暖和空调已经成为普遍的要求。作为中国传统供热的燃煤锅炉不仅能源利用率低，而且还会给大气造成严重的污染，因此在一些城市中燃煤锅炉在被逐步淘汰，而燃油、燃气锅炉则运行费用很高。地源热泵就是一种在技术上和经济上都具有较大优势的解决供热和空调的替代方式。

地源热泵是利用浅层地能进行供热制冷的新型能源利用技术，是热泵的一种，热泵是利用卡诺循环和逆卡诺循环原理转移冷量和热量的设备。地源热泵通常是指能转移地下土壤中热量或者冷量到所需要的地方。通常热泵都是用来做为空调制冷或者采暖用的。地源热泵还利用了地下土壤巨大的蓄热蓄冷能力，冬季地源把热量从地下土壤中转移到建筑物内，夏季再把地下的冷量转移到建筑物内，一个年度形成一个冷热循环。地能或地表浅层地热资源的温度一年四季相对稳定，冬季比环境空气温度高，夏季比环境空气温度低，是很好的热泵热源和空调冷源，这种温度特性使得地源热泵比传统空调系统运行效率要高40%，因此要节能和节省运行费用40%左右。地源热泵技术以其节能、环保、可再生能源利用的特性在我国得到了迅猛发展，在武汉也得到了大量的工程应用，本文梳理和总结了武汉地区地源热泵技术应用和发展现状，并从多方面剖析了地源热泵发展和工程应用中存在的主要问题，提出了武汉地源热泵应用和发展的对策建议。

Abstract

With the development of economy and the people living standard rise, public buildings and residential heating and air conditioning has become a universal requirement. As Chinese traditional heating coal-fired boiler is not only low energy efficiency, but also will cause serious pollution to the atmosphere, thus coal-fired boiler in being phased out in some cities, while the fuel and gas boiler operation cost is very high. Ground source heat pump is a technically and economically has bigger advantage solution alternative heating and air conditioning.

Ground source heat pump is the use of shallow ground to heat and cooling of the new energy utilization technology, is a kind of heat pump, heat pump is the use of carnot cycle and reverse carnot cycle principle of heat transfer and cooling capacity of the equipment. Ground source heat pump can usually refers to the transfer of underground heat or cold quantity in the soil to where it is needed. Heat pump is frequently used as a air conditioning refrigeration or heating. Ground source heat pump has also used the underground soil enormous accumulation of heat storage capacity, the winter ground source heat transferred to the building from the underground soil, summer to transfer the cold underground to buildings, a year to form a hot and cold cycle. Can or simple layer of geothermal resources of the earth's surface temperature is relatively stable throughout the year, higher than the ambient air temperature in winter, the summer than the ambient air temperature is low, it is a good heat source of heat and air conditioning cold source, the temperature characteristic makes the ground source heat pump is 40% higher than traditional air conditioning system operation efficiency, therefore to energy efficiency and save operating cost by about 40%. Ground source heat pump technology, with its characteristics of energy saving, environmental protection, renewable energy has been rapid development in our country, also get a number of engineering application in wuhan, this paper review and summarize the wuhan area ground source heat pump technology application and development situation, there are many ways for the analysis of the
