摘要

当今能源紧缺问题严重，回收空调冷凝热用来制备生活热水可以节约部分能源，因此设计制作了相变蓄热冷凝热回收系统，并进行了相变蓄热实验、空调运行及有无相变蓄热器运行参数对比实验、蓄热器放热实验及冷水温升与流量的关系实验、空调运行制取热水实验。可以看出

利用在空调系统中增加相变蓄热器的方法可以有效回收空调机组的冷凝显热。空调系统在增加蓄热装置后，运行状况良好。相变蓄热器放热过程中，大流量情况下冷水的温升偏小。如放热过程中空调机组同时运行，可以相应提高冷水升高的温度。

Abstract

Utilization of air-conditioning condensing heat recovery in daily hot water preparation was propitious to energy conservation.Condensing heat recovery system based on thermal storage of phase change material was designed and analyzed in this paper.Related studies such as thermal storage and heat releasing experiment

comparison between air conditioning system with or without the thermal storage device

relationship between temperature rise and flow rate

making hot water during air-conditioning running were also conducted.It could be proved that sensible heat of condensation could be recovered effectively by the way of installing thermal storage device in this system.Air conditioning system kept in good situation with condensing heat recovery unit.Experiments showed larger flow rate lead to less temperature rise of cold water during the discharging process of thermal storage device.And that several air conditioning units run simultaneously could improve the temperature rise of cold water.
