Refrigerant options in the coming future

Regulation (EU) no. 517/2014 on fluorinated greenhouse gases (the F-gas regulation) and today's research in the refrigeration and air-conditioning technology and heat pumps are increasingly focused on the use of natural refrigerants such as ammonia, carbon dioxide and hydrocarbons. Except for having zero ozone depletion potential, refrigerants should have their global warming potential as low as possible. In a way, the said Regulation promotes the use of sustainable technologies and sustainable natural refrigerants in refrigeration systems. The paper gives an overview, application and basic properties of refrigerants in refrigeration equipment and heat pump systems. The emphasis is on natural refrigerants that are gradually being used as a replacement for refrigerants from the hydrofluorocarbon (HFC) group. Furthermore, the HFC refrigerant group is analyzed in the context of F-gas regulation. Also, the hydrofluoro-olefin (HFO) refrigerant group, which is currently being used in automotive cooling systems, is listed. The paper also contains total equivalent warming impact (TEWI) number calculations of cooling plants for cooling buildings with a known cooling load. The comparison is given for different types of refrigerants with the purpose of better understanding their ecological impact
