Review of Heating and Cooling Applications where HCs have been Introduced as Refrigerants and Future Perspectives of their Use
This paper aims to review some applications where the use of hydrocarbons, either due to the operating environment or the refrigerant quantity required, is currently considered the most viable solution. Examples include household refrigerators, dryers, and small commercial refrigeration units. The paper will also explore other applications such as heat pumps, commercial refrigeration systems, refrigerated transport, and high-temperature heat pumps, where their use may eventually be adopted in part of the sector. Additionally, the review will address some existing barriers and potential development paths to expand their usage.
