R407C房间空调器系统性能模拟与换热部件优化分析

Simulation and Optimization Research on Systematic Performance of Room Air-conditioner Using R407C

对替代房间空调器用制冷剂R2 2的R40 7C工质的应用进行了研究 ,分别建立了空调器主要部件 (蒸发器、冷凝器、压缩机、毛细管和连接管道 )的分布参数模型 (除压缩机模型外 ) ,并对空调器进行了模拟。且就换热器的结构参数编制了优化模块 ,获得了一些有参考价值的研究结果。

The research is conducted on R407C with the incoming date of forbiddance to use the refrigerant 22 in residential air-conditioners,The new-style refrigerant replacing the traditional Freon refrigerant R22.Distributed parameter models of major components,such as evaporator,condenser,capillary and connecting pipe are established respectively.Based on them,the dynamic changes of air-conditionerand the influences of each parameter on R407 air-conditioning system could be forecast.Meanwhile the theoretic and technical supports are obtained for popularizing R407C to residential air-conditioner.Finally,the optimizing module on configuration parameters of heat exchangers is programmed for offsetting R407C's negative influence.
