Condensation of Natural Refrigerant Mixtures in Horizontal Smooth Tube - Prediction Model and Calculation Results
نویسندگان
چکیده
This paper deals with the heat exchange performance prediction of a counter flow double-tube condenser for binary natural refrigerant mixtures (propane/n-butane & propane/i-butane ). The local characteristics of the heat transfer and pressure drop are calculated using a prediction method developed by authors, and the total pressure drop, the overall heat transfer coefficient and the average heat transfer coefficient are evaluated on various heat transfer conditions. It is confirmed that heat transfer performance of the natural refrigerant mixtures is higher than that of HCFC22 in most cases.
