R-32 (Difluoromethane) is a pure HFC-type refrigerant with a relatively low global warming potential. It is characterized by being a refrigerant with a large cooling capacity at low temperatures and good thermodynamic efficiency. As an A2l medium-safe refrigerant with regard to flammability, the instructions of the refrigeration plant safety regulations regarding the load of equipment must be observed. On the other hand, it is the most commonly used refrigerant in new air conditioning equipment.
