R-410A is a mixture of difluoromethane and pentafluoroethane, used in air conditioning and heat pump applications. It has lower ozone depletion potential than R-22, but higher global warming potential, and will be phased out by 2036 in the US due to the AIM Act.
A comprehensive table of refrigerants sorted by their ASHRAE numbers, chemical names, formulas, properties and safety groups. Learn about the types, structures, effects and applications of different refrigerants, including CFCs, HFCs, HCFCs and natural gases.
Learn about the different kinds of refrigerants used in air conditioning and heat pump systems, and how they have evolved over time to reduce their environmental impact. Find out how refrigerants are classified, controlled and phased out according to international agreements and policies.
R-454B is a mixture of 68.9 percent R-32 and 31.1 percent R-1234yf, with a GWP of 466. It is intended to replace R-410A in new equipment, as it has lower global warming potential and is non-toxic and mildly flammable.
R-407C is a blend of difluoromethane, pentafluoroethane, and tetrafluoroethane used as a replacement for R-22. It is colorless, odorless, non-flammable, and has moderate global warming potential.
Learn about the most widely used method for air conditioning and refrigeration, which involves a circulating liquid refrigerant and four components: compressor, condenser, expansion valve, and evaporator. Find out the types, advantages, and disadvantages of different refrigerants and their impact on the environment.
Difluoromethane is an organic compound with the formula CH2F2, used as a refrigerant and fire extinguishant. It has a low melting and boiling point, a high thermal stability, and a low ozone depletion potential, but a high global warming potential.
Learn about the thermodynamic principles and types of heat pump and refrigeration systems, such as vapor compression, absorption, and gas cycles. Find out how they operate between hot and cold temperatures and how they are used for heating and cooling applications.
