摘　　要：本文对R32/R125/R134a三元非共沸混合制冷剂在实现变组成容量控制的组成调节装置中的分离器即填料塔中的传热传质过程进行了理论分析,建立了初步的热质传递模型。对热质传递模型的计算结果进行了分析比较,说明本文建立的热质传递模型是合适正确的。A theoretical analysis is conducted for the heat and mass transfer in the separation process of ternary non-azeotropic mixture R32/R125/R134a in a packed tower. A preliminary model is established to describe the process of heat and mass transfer. Comparison and analysis are made for the numerical results of the heat and mass transfer model with a conclusion that the model presented in this paper is basically fit to the actual physical process.
