Kylmäainekaasut
Kylmäainekaasut, also known as refrigerants, are substances used in refrigeration and air conditioning systems to transfer heat. They are typically fluids that undergo phase changes, evaporating at low temperatures and pressures and condensing at higher temperatures and pressures. This cyclical process allows them to absorb heat from a colder space and release it into a warmer environment.
Historically, many refrigerants were based on chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). However, due to their detrimental
Current refrigerants include hydrofluorocarbons (HFCs), which do not deplete the ozone layer but still possess significant
The selection of a refrigerant depends on various factors, including the specific application, operating temperature range,
