本文用新型无接触热阻全铝换热器对传统家用空调换热器进行了替代设计，利用空气焓值法对使用新型换热器和管片式换热器的家用窗式空调器进行对比实验，优化并测试了毛细管规格和制冷剂充灌量对新型换热器空调系统制冷性能的影响。研究结果表明：新型无接触热阻全铝换热器在换热面积减小37.53％时，制冷量反而提高3.59％，能效比EER提高7％。新型换热器有更强的换热能力，是目前家用空调换热器的理想替代产品。

In order to replace the traditional heat exchanger of room air conditioner,a new non-contact thermal resistance aluminum heat exchanger was designed. Enthalpy method is then used to compare the cooling performance between new heat exchanger and tube-fin heat exchanger of household air conditioner. The capillary size and refrigerant charge capacity of air conditioner are tested and optimized for better cooling performance. The results show that the heat transfer area of the new non-contact thermal resistance aluminum heat exchanger is decreased 37. 53%,the rated cooling capacity is just reduced by 2. 7%,EER increased by 7% instead. The new heat exchanger has a stronger heat capacity and is the ideal alternative product for heat exchangers of room air conditioners.
