Low GWP Refrigerants | Mobile Air-Conditioning | Stationary Air-Conditioning | Domestic Refrigeration | Industrial Refrigeration | Commercial Refrigeratio
A refrigerant is the essential working fluid in a vapor-compression refrigeration cycle; it absorbs heat at a relatively low temperature in the evaporator (for example, the cooling coil in an air conditioner) and releases it at a higher temperature in the condenser (for example, the outside coil).
What are Low GWP Refrigerants?
The low global warming potential (GWP) refrigerants are used in a wide range of types including, ventilation, heating, air conditioning and refrigeration (HVAC&R) equipment. The low GWP refrigerants are used to maintain the high level of system efficiency and also exhibit significantly lower flammability characteristics, than much more flammable hydrocarbons. The growing emphasis on global warming mitigation has enthused the interest in low GWP refrigerants.

Due to the growing global concerns around the use of refrigerants with relatively high global warming potential, new working fluids with the positive attributes of both high thermal performance and low environmental impact are currently in development. These refrigerants exhibit promising performance when compared with refrigerants currently used in AC systems such as R-410A and R-407C. They also show significantly lower flammability characteristics than the much more flammable hydrocarbons. Replacements for common HFC refrigerants such as R-407C and R-410A are discussed for residential air conditioning applications. Thermal properties, as well as experimental results in representative air conditioning systems, are presented, showing the benefits of using these new working fluids.
