‌R410A refrigerant‌ is a new type of environmentally friendly refrigerant, mainly composed of R32 (difluoromethane) and R125 (pentafluoroethane) mixed in a ratio of 50%, and belongs to the HFC class of substances. R410A does not damage the ozone layer and does not contain chlorine, so it will not react with ozone. It has the characteristics of stability, non-toxicity, and superior performance. ‌

Physical properties
R410A is colorless and transparent in appearance, with a boiling point of -51.6℃ and a freezing point of -155℃. Its molecular weight is 72.58, the critical temperature is 72.13℃, and the critical pressure is 4.95MPa ‌

Application fields
R410A is widely used in household air conditioners, small and medium-sized commercial air conditioners, mobile air conditioners, dehumidifiers, refrigerated dryers, marine refrigeration equipment, industrial refrigeration and other fields. Due to its high efficiency and environmental friendliness, R410A has become a medium- and long-term alternative to R22 refrigerant and has been popularized in Europe, America, Japan and other countries.

High efficiency: The cooling capacity of R410A has been significantly improved, making it possible to design smaller and more compact air-conditioning equipment.

Stability: R410A has near-azeotropic properties and will not undergo significant separation in the entire operating range. There is no need to discharge the remaining refrigerant in the system during maintenance.

Environmental friendliness: It does not contain chlorine, does not damage the ozone layer, and is in line with global environmental protection concepts.

Disadvantages:

High pressure: The working pressure of R410A is about 1.6 times that of R22, and the system pressure-resistant components need to be stronger.

High global warming potential: Although it is environmentally friendly, it does not increase greenhouse gas emissions. Its global warming potential is 1725 times that of carbon dioxide.
