地源热泵技术在中国温室设施中的应用探讨

当前在中国温室设施中应用和推广地源热泵技术尚存在诸多不利因素,大大限制了该项技术在设施农业领域中的发展。为探寻合理的解决途径,对地源热泵空调系统的关键技术和其在中国的发展概况进行了相关的阐述和分析,并以中国农业大学上庄实验站已经建成使用的地下水式温室地源热泵空调系统为实例,介绍该系统的组成、工作流程、性能参数和使用情况,探讨温室地源热泵空调系统在推广和使用中可能出现的投资较高,长时间运行性能不稳定等问题,分析其原因并提出相应的对策建议。

Discussion on Application of Ground Source Heat Pump Technology in Greenhouse Establishment of China

The application and popularization of greenhouse ground source heat pump air-conditioning system still be confront with lots of disadvantages currently in China,limited the development of technology in the field facility agriculture greatly.In order to explore reasonable way to solve the problem,the authors expatiated and analyzed the key technique and the general development actuality of the ground source heat pump air-conditioning system in China.Meanwhile,set the ground water style ground source heat pump air-conditioning system which has been constructed and used in Shangzhuang experimental site of china agricultural university as example,introduced the compose,work process,performance parameters,and the running situations of the system.Discussed the issues which be likely to emerged,such as higher investment and unstable performance after longtime running.analyzed the causes and come up with some countermeasures.
