A New Start for R410A Refrigerant

commonly used refrigerants for air conditioning

R410A refrigerant is a new type of environmentally friendly refrigerant that does not destroy the ozone layer. The working pressure is about 1.6 times that of ordinary R22 air conditioners, and the cooling (warming) efficiency is high. R410A new refrigerant is composed of two quasi-azeotropic mixtures R32 and R125, each of which is 50%, mainly composed of hydrogen, fluorine, and carbon elements (expressed as HFC), and has the characteristics of stability and superior performance. At the same time, because it does not contain chlorine, it will not react with ozone, that is, it will not destroy the ozone layer.

In addition, the performance of air conditioners using new refrigerants will also be improved to a certain extent. R410A was once an internationally recognized refrigerant to replace R22 and was popularized in Europe, America, Japan, and other countries. Global trends and prospects of R410A refrigerant replacement in major international markets, usage status, and entry into international markets. Main application: R410A is a widely used medium and high-temperature refrigerant, mainly used in household air conditioners, small and medium commercial air conditioners (small and medium unit air conditioners, household air conditioners, multi-connection), mobile air conditioners, air energy heat pumps, industrial refrigeration and other refrigeration equipment.

R410A refrigerant is the choice to replace Freon R22 on new refrigeration equipment (usually air conditioning systems). However, since R410A and R22 have different pressures and compressor oil, etc., for the after-sales maintenance of refrigeration equipment initially installed as R22, if it is necessary to add or replace the refrigerant, only R22 can still be added, and usually, R410A cannot be used directly. Replace R22 (that is to say, exchange-type replacement is usually not possible. However, for the refrigeration equipment that uses R22 for the initial installation, R410A can be used to directly replace R22 during maintenance or replacement)

R410A is colorless in appearance, not cloudy, volatile, boiling point -51.6℃, freezing point -155℃.
