Optimization Option of Refrigerant Mixture in Heat Pump for Waste Heat Recovery in Power Plant

摘要

According to characteristics of the low-temperature heating technology and requirements of the heat pump for waste heat recovery, the physical properties of conventional refrigerants in heat pump are preliminary screened. Three kinds of refrigerant mixtures were selected. And then performance of heat pump cycle for three refrigerant mixtures selected analyzed by CSD equation. According to analyzed results of heat pump cycle performance and physical properties, SMR02 and 03 is the best refrigerant mixture.
