摘要

为了揭示空调工况下非共沸制冷剂在冷凝器中的换热特性，探明制冷剂和换热流体间温差的沿程变化规律，进行了相应的理论分析.建立了制冷剂的冷凝换热模型，根据标准的空调工况确定了制冷剂的冷凝物性参数.利用制冷剂状态方程得到冷凝过程中温度与焓值的对应关系，进而计算出制冷剂和换热流体在冷凝过程中的温差.通过归纳沿程位置的温差变化，得到它的变化规律，为合理设计冷凝器提供了一定的理论依据.

Abstract

Researches were carried out to reveal some heat exchange characteristics of non-azeotropic refrigerants during condensation

and understand the change of temperature difference (between refrigerant and heat transfer fluid).Firstly

a model of refrigerants condensation was built

and refrigerants properties parameters were decided for the air-conditioning operation.Secondly

the equation of state of refrigerants was used for computing and obtaining some relationship between temperature and enthalpy

and the temperature differences between those refrigerants and heat transfer fluids were obtained.Through analyzing those temperature differences

a rule of temperature change was found.The rule may be helpful to designing condensers in air-conditioning unit or heat pump unit.
