1、摘 要 I 摘 要 随着中国的建筑行业的飞速发展，人们对生活环境的要求也越来越高，而生活环境最主要的就是居住环境，这种需求带动了中国的空调制冷业的发展，人们对室内空气品质（ IAQ）有了更深刻的认识，室内空气的好坏直接影响到人们的健康，原来使用的空调技术已经不能满足人们的要求，对环境的需求意识已经不是简单的冷热意识，而是趋向于健康化、卫生化的需求。因此采用更先进的空气调节方法提高空气品质满足人们的要求成了当前制冷行业发展的热点和重点之一。 近些年来 ，由于大中城市电力供应紧张，供电部门开始重视需求管理及 削峰填谷，热泵供热技术提到了议事日程。近年来，由于能源结构的变化，促进了地源热泵供热机组的

2、快速发展。 随着生产和科技的不断发展 ,人类对地源热泵供热技术也进行了一系列的改进 ， 同时也在积极研究环保、节能的地源热泵供热产品和技术 ， 现在利用成熟的电子技术来进行综合的控制，并和太阳能结合更注意能源的综合利用、节能、保护环境及趋向自然的舒适环境必然是今后发展的主题。 地源热泵技术，是利用地下的土壤、地表水、地下水温相对稳定的特性 ,，通过消耗电能，在冬天把低位热源中的热量转移到需要供热或加温的地方，在夏天 还可以将室内的余热转移到低位热源中 ,达到降温或制冷的目的。地源热泵不需要人工的冷热源 ,可以取代锅炉或市政管网等传统的供暖方式和中央空调系统。冬季它代替锅炉从土壤、地下水或者地表

3、水中取热 ， 向建筑物供暖 ； 夏季它可以代替普通空调向土壤、地下水或者地表水放热给建筑物制冷。同时 ， 它还可供应生活用水，可谓一举三得，是一种有效地利用能源的方式。 本文，将通过学习有关地源热泵和中央空调系统设计方面的书籍与资料，在老师的的指导和同学们的帮助下，用自已大学四年所学过的专业和努力设计一套土壤源热泵中央空调系统。希望借此机 会检验我大学四年所学专业的成果，并使我的专业知识系统得到一次升华。 关键词：地源热泵；中央空调；节能环保；设计 东北电力大学本科毕业论文 II Title: Design of Ground Source Heat Pump central Air-cond

4、itioning system ABSTRACT With the rapid development of Chinas construction industry,Peoples requirements of the Living environment is becoming higher and higher.And the most important part of it is the living environment,This demand contributed to the Chinas air conditioning refrigeration industry d

5、evelopment.People have a more profound understanding of the in indoor air quality,the indoor air has a direct influence on the peoples health,so the original use of air conditioning technology can not satisfy the requirement of people.Peoples requirement on the environment is not simple consciousnes

6、s for cold and hot consciousness,but tend to health,and the demand of sanitation.So use the more advanced air conditioning method is becoming one of the most important part of the development of the current refrigeration industry to improve the air quality and meet the requirement of people. In rece

7、nt years,due to the power supply constraints of large and medium cities,the power supply departments becoming paying more attention to needs and Let people use less power in the peak of the electrical energy.So the heat pump heating technology is mentioned to the agenda.In recent years,due to the ch

8、ange of the structure of energy,the ground source heat pump heating units is developing faster and faster. As the development of the production and the science technology,human also conducted a series of improvements of ground source heat pump heating technology.At the same time they also try to fin

9、d ways to make the ground source heat pump more environmental and Energy saving.Now use the mature electronic technology to carry out comprehensive control and combined with the solar energy to pay more attention to the comprehensive utilization,energy saving,the protection of the environment,must b

10、e the theme of the development in the future. The ground source heat pump technology,is a technology which use the Abstract III characteristics of temperature is relatively stable of the soil underground,surface water,groundwater to transfer heat from ground to anywhere that need it in the winter or

11、 cool the indoor temperature by let the heat flue into the ground.The ground source heat pump does not need a man-made cold source,it can take the place of the traditional heating and central air conditioning system such as the boiler or municipal pipeline.It can also supply the water for living,wha

12、t a convenient way it is. In this paper,I will design a set of ground source heat pump system with my teacher and classmates help,by using the knowledge that I learned during these four year and looking through books about the ground source heat pump central air conditioning.I hope I can learn more about my subject from this design。 Key Words： ground source heat pump； Design； central air conditioning； energy saving
