Improving air conditioning performance, do not damage the ozone layer. R410A new refrigerant composed of two quasi-azeotropic mixture is made mainly of hydrogen, fluorine and carbon elements (expressed as hfc), with a stable, non-toxic, superior performance characteristics. And because no chlorine, it will not react with ozone, neither destroy the ozone layer. In addition, the introduction of new air conditioning refrigerant and also some improvement in terms of performance. R410A is by far the most internationally recognized right to replace the R22 refrigerant, and has been popular in Europe, Japan and other countries.

R-410A refrigerant as a high temperature in widespread use today, mainly used in home air conditioners, commercial air conditioners SMEs (small and medium sized unitary air conditioners, residential central air-conditioning, multi-line), mobile air conditioning, dehumidifiers, refrigerated dryers, Marine refrigeration equipment, industrial refrigeration and other refrigeration equipment.

R410A refrigerant is an alternative of R22 to the newly installed refrigeration equipment best and final selection (usually air-conditioning systems); but due to different pressures R410A and R22 (R410A pressure is much higher than the R22) and compressor oil, etc. are not the same , so for the initial installation of R22 refrigerant refrigeration equipment Repairs, if need to add or replace the refrigerant, still only add R22, usually can not directly R410A instead of R22 (ie usually not exchange transfusion style Replace; but for the initial installation of refrigeration equipment using R410A, repair or replacement can be directly replaced with R22 R410A).

Replace R410A global trends and prospects in the major international markets usage and access to international markets dynamic physical properties of materials R410A, it is a mixed refrigerant, it is by R32 (difluoromethane) and R125 (pentafluoroethane) Composition The mixture has the advantage that it can according to the specific requirements of the various properties, such as flammability, capacity, and efficiency of the exhaust gas temperature to be considered, tailored synthesis of a refrigerant. R410A Colorless, no cloudy, volatile, boiling point -51.6 ℃, freezing point of -155 ℃; its main features are:

(1) does not destroy the ozone layer. No chlorine in its formula, so the ozone depletion potential (ODP) of zero. Global warming potential (GWP) of less than 0.2.

(2) very low toxicity. Similarly allowable concentration and R22 are 1000ppm.

(3) Non-flammable. Combustible air polarity 0.

(4) high chemical and thermal stability

(5) water solubility and is almost the same as R22.

(6) is a mixed refrigerant composed of two refrigerants

(7) immiscible with mineral oil or alkylbenzene oil. (With POE [ester lubricants], PVE [ether lubricants] compatibility)
