What Is Refrigerant

Refrigerant, also known as refrigerant or snow seed, is a medium used in various heat engines to complete energy conversion. These substances typically increase power through reversible phase transitions (such as gas-liquid phase transitions). Such as steam in steam engines, snow in refrigerators, and so on. During operation, a typical steam engine releases the thermal energy of the steam and converts it into mechanical energy to generate the original power; The snow seed of the refrigerator is used to transmit heat from low temperatures to high temperatures.
The common working medium in traditional industry and daily life is partially halogenated hydrocarbons (especially chlorofluorocarbons), but they are gradually phased out due to their ability to cause ozone layer voids. Other widely used working media include ammonia, sulfur dioxide, and non halogenated hydrocarbons (such as methane).
