提出一种由空气处理器和金属辐射板作为双温蒸发器的新型空调制冷系统和相应的混合制冷理论循环。新型空调制冷系统主要由压缩机﹑冷凝器﹑两个热力膨胀阀﹑喷射器和双温度蒸发器构成。本文对制冷循环的性能以及室内空气处理过程进行了热力学分析和对比，结果表明；双温空调制冷理论循环的性能可比常规带新风的空调器提高13.73﹪，制冷系数可达7.43；当室内新风负荷和湿负荷较大的情况下，双温空调的制冷性能系数会有所降低，但仍比常规空调器的理论性能系数高5.21﹪。

An innovative dual_temperature air conditioning system and the corresponding mixed theoretical refrigeration cycle were pro_posed.The new air_conditioner consists of an air handling unit and a metal radiation panel as its dual_temperature evaporators, a compres_sor, a condenser, two thermal expansion valves and an ejector.The state properties in the air handling process and the theoretical refrige_ration cycle were analyzed and compared with those of the conventional air conditioner with fresh air.Results indicate that the coefficient of performance(COP)of the dual_temperature theoretical refrigeration cycle may be improved by 13.73﹪ to 7.43.But the COP of the du_al_temperature refrigeration cycle will drop by somewhat as the amount of fresh air required and indoor moisture increases.However, it is still greater than the COP of the conventional air conditioner by 5.21﹪.
