Significant progress is being made in the development and testing of low GWP alternatives to hydrofluorocarbon (HFC) and hydrochlorofluorocarbon (HCFCs) refrigerants. This seminar focuses on several applications of refrigerant development including air conditioning, high temperature heat pumps and refrigeration. Of particular concern is development of new refrigerants for air conditioning that perform well at high ambient temperatures such as in the Middle East. Some regions are just beginning their transition away from HCFC-22 and are looking for low GWP HCFC-22 alternatives with similar performance. Information is also presented on refrigerant/lubricant property development including miscibility, solubility and viscosity properties.
