新型空调冷凝水相变蓄冷系统可行性分析

Feasibility Studyon a New Cooling Storage System of Phase Change with Condensate in Air Conditioning

指出了分体式空调由于其具有安装快捷、使用方便的优点,已经广泛应用于居民用户当中。然而,“空调雨”的问题一直没有得到有效地解决。综述了目前冷凝水利用和相变蓄冷的研究现状,提出了一种空调冷凝水相变蓄冷系统,该系统能够收集白天制冷产生的低温冷凝水,并通过相变蓄冷材料将冷能储存起来;到了夜间,通过相变材料释放冷量给房间供冷,从而降低了空调的运行能耗。计算了分体式空调冷凝水的日产生量,并对该系统进行了节能潜力分析,得出了该系统可以起到节能减排的作用。

Split air conditioning has been widely used in residential users because of its advantages of fast installation and convenient use.However,the problem of“air conditioning rain”has not been effectively solved.The current research status of condensate utilization and phase change storage is reviewed.A phase change refrigeration system for air conditioning condensate is proposed.The system can collect the low temperature condensate produced by refrigeration on daytime and store the cold energy through phase change refrigeration materials.At night,the cooling capacity contained in thephase change materialsis released to the room,which reduces the energy consumption of the air conditioning operation.The daily production of condensate in split air conditioning is calculated,and the energy saving potential of the system is analyzed.It is concluded that the system can save energy and reduce emission.
