jäähdytysaineissa
Jäähdytysaineissa, known in English as refrigerants, are substances used in refrigeration and air conditioning systems to absorb heat from a low-temperature reservoir and release it to a higher-temperature reservoir. They undergo a phase change, typically from liquid to gas and back to liquid, during the refrigeration cycle. This phase change is crucial for their heat-transferring properties.
Historically, various compounds have been used as refrigerants. Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) were widely adopted
Hydrofluorocarbons (HFCs) were introduced as replacements for CFCs and HCFCs. While they do not deplete the
Current research and development focus on refrigerants with low GWP and ODP, often categorized as natural refrigerants
