摘要

根据能量梯级利用原理，提出一种将水蓄热与相变材料蓄热结合在一起的复合蓄热热回收空调系统，即在空调机组冷凝器上串联一个相变蓄热器和一个水蓄热器，从压缩机出来的高温高压制冷剂过热蒸汽首先经过相变蓄热器，使品位较高的过热以潜热的形式储存于相变材料中。再经过水蓄热器，将部分温度较低的相变热储存于水中。实验表明，该系统能有效地回收19.6%的冷凝热，其中在空调关闭后通入较小流量的冷水即可制取温度在40℃以上的生活热水；在空调运行的条件下，通入较大流量的冷水可连续制取温度在40℃以上的生活热水。该系统达到了节约能源、满足生活热水需求一举两得的目的。

Abstract

According to the principle of cascade use of energy

a recycling air conditioning system combining water thermal storage and phase change material (PCM) thermal storage was presented.A water thermal storage and a phase change thermal storage are installed in series before the air cooled condenser.Superheated refrigerant vapor from the compressor flows through the phase change thermal storage first

the heat of superheating being stored in it

and then flows through the water thermal storage and exchanges heat with the water.Part of latent heat of condensation is stored in water thermal storage.The result of the experiments indicated that the heat recovery air conditioning system can effectively recover 19.6% of the condensing heat. When air conditioning does not work

the hot water produced under smaller flow rate is above 40℃ and produced under greater flow rate is above 40℃ also with air conditioning working. It not only can save energy but also satisfy the hot water demand of users.
