摘要
浅层地源热泵是一种利用高位能使浅层地能从低位热源转移到高位热源的机械装置。该文回顾了浅层地源热泵的种类及各自的优缺点,重点介绍了地源热在国内外的发展背景与意义,探讨了浅层地源热泵技术在设施农业中的研究进展及存在的问题如初期投资高、控制水平低等,并结合存在的问题提出相应的对策和建议。
Ground soure heat pump is a kind of mechanical equipment which can transform low-temperature heat source into high-temperature heat source. In this paper, the authors summarized the kinds of heat pumps and their respective advantages and disadvantages, mainly introduced the prensent situation of ground soure heat pump in overseas countries and China, discussed the research progess and the existing problems of heat pump in emerging protected cultivation, such as higher investment and low levels of control. The present research characteristics and some countermeasures were also presented.
