| 摘 要： | 套管式冷凝器广泛应用于各种小型制冷装置系统。本文针对混合制冷工质在套管式冷凝器中的冷凝过程,依据混合工质在冷凝过程中存在温度滑移的特性,分析了气液相各组分质量百分数随温度变化的特性。应用混合制冷工质物性计算软件Refprop8.0分析了其初始过热状态质量成分比例一定时,在温度不断降低情况下,气相和液相中质量成分的变化规律。通过传热学理论及换热器设计理论,较详细地分析计算了混合制冷工质在套管式冷凝器中冷凝时的热力参数,并得到了这种工况条件下套管式冷凝器的几何尺寸。

| Abstract: | Double-pipe Condenser is widely used in various small refrigeration systems.Based on the condensation process of mixed refrigerants in double-pipe Condenser and the temperature slip characteristic of mixed refrigerant,mass percentage with temperature characteristics is obtained of gas and liquid phase.In a certain mass ratio,physical property of mixed refrigerant is get with the application of the commercial software Refprop.In the temperature decreases case,the composition change regularity of gas and liquid phase mass components is acquired.By the theory of heat transfer and heat exchanger design theory,the thermodynamic parameters of mixed refrigerant are analyzed in double-pipe condenser.The geometric dimensions are gained under the working conditions of the double-pipe condenser. |
