Technical characteristics of r410a refrigerant used in air conditioners

Do you know the technical characteristics of r410a refrigerant used in air conditioners? It doesn't matter if you don't understand, the following editor will take you to understand.

r410a refrigerant is a mixture of HFC-32 and HFC-125 (50%/50% mass ratio). It is used as a replacement for R-22 refrigerant air-conditioning fixed system, but it cannot be applied to the original R22 equipment. It cannot replace R22. R-410A has proved that the energy efficiency ratio is increased by 5 to 6%, which is higher than that of R-22. It also has a higher capacity and release pressure than R-22, making the design of the air conditioner smaller and more compact.

It is an almost azeotropic binary mixture of HFC-32 and HFC-125, which has a floating temperature below 0.2°C. Its properties are very similar to an azeotrope, and it can be regarded as a single refrigerant. This means that they will not destroy the system and its combination ratio, nor will it change in the event of a leak. The diameter of the cylinder cannot be too large, and the discharge volume of the compressor is not more than 32cm3, so the piston machine can separate the composition and have dangerous compression force. The vapor compression cannot exceed a certain space, which is dangerous! This is very important, so fluoride must be added in a liquid state.

The excellent thermodynamic properties of r410a refrigerant can use more compact compressors, smaller diameter tubes, higher speeds and better equipment, because it has more Low energy consumption. R410a refrigerant is compatible with mineral oil or alkylbenzene oil, because R410A will not mix with them. The oil specified for R-410A is polyol (POE) oil. These oils should not be exposed to open air and can only be opened before use. Tools and parts must be r410a refrigerant. Never use a conventional meter to charge refrigerant, measure the pressure and watch them (explosive tube, exploded meter) just in case.

This is the end of the above introduction about r410a refrigerant. I hope to bring you some help. If you have a demand for r410a refrigerant, please feel free to consult us We serve you wholeheartedly.
