摘要

提出了一种新型蓄冷和热水器复合空调器装置.蓄冰槽在低谷电和夜晚室外温度较低时蓄冷

然后利用蓄冷提高冷凝器出口制冷剂的过冷度

不但增大空调器的制冷量

而且充分利用蓄冰槽内的显热量.放冷结束后

通过调节阀门

蓄冰槽可转换成水冷冷凝器

复合空调器变成热泵热水器

提供生活热水的同时

可以提供一定的制冷量.通过对普通空调器改造的样机进行了夏季工况下运行的实验研究

研究了蓄冰槽盘管不同结构和位置对蓄冰的影响.同原来空调器比较

复合空调器制冷量平均增加28.2%

性能系数平均增加21.5%.复合机组提供热水时平均性能系数为2.77.即提供相同热量热水

复合机组用电量仅为电热水器的36%.提供热水期间平均的制冷量为2325.39w.

Abstract

Air conditioner with a new hybrid equipment of cooling storage and water heater (ESWAC) is proposed and designed. In summer

storage coils worked as evaporator and ice storage was done during off-peak electrical demand period

and then storage coils were used as super cool exchanger to supercool the refrigerant from the condenser. It cannot only balance power load

but improves the coefficient of performance (COP) of the air conditioner. Moreover

ESWAC can be HP water heater to supply hot water. Finally

experimental study for the operation process of ESWAC prototype has been done. The influence of different structure and position of coils on the performance of ESWAC was studied during the charging period. The results show that ESWAC is feasible. Compared with original air conditioner

average cooling capacity increases by 28.2%

and COP increases by 21.5%. The power of ESWAC is only 36% of that of electrical water heater with the same capacity of hot water.
