Study and Analysis on Double - pipe Condenser for Condensing Mixed Refrigerant
摘要
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 ihe theory-of heat transfer and heat exchanger design theory, the ther-modynamic parameters of mixed refrigerant are analyzed in double - pipe condenser. The geometric dimensions are gained under the working conditions of the double - pipe condenser.关键词
