【Abstract】 The study on R407C acting as a substitute for R22 is reviewed. The review indicated that it should give priority to experimental studies and pay all-around considerations from security?thermodynamics characteristic?heat transfer performance and application to make the new refrigerants furthest applying to the existing refrigeration and air-conditioning system when new refrigeratns acted as substitutes.更多还原
