Refrigerant r410 is a blend of HFC-32 and HFC-125 (50%/50% by mass). It is used as an alternative to the R-22 refrigerant air conditioning fixed system, but it cannot be applied to the original R-22 equipment. It cannot replace R22.

Refrigerant r410 has proved that the energy efficiency ratio is increased by 5-6%, which is higher than that of R-22. It also has a higher capacity and relief pressure than R-22, allowing air conditioning units to be designed smaller and more compact. Refrigerant r410 increases by nearly 60% pressure to R22, but its discharge pressure and suction pressure have the same compression ratio as R22.

It is an almost azeotropic binary mixture of HFC-32 and HFC-125, which has a floating temperature below 0.2°C. It behaves very much like an azeotrope and can be thought of as a single refrigerant. This means they will not disrupt the system and its combined proportions, nor will it change in the event of a leak.

The diameter of the cylinder should not be too large, and the discharge volume of the compressor should not be larger than 32cm3, so the piston machine can separate the composition and have a dangerous compression force. Vapor state compression can not exceed a certain space, dangerous! This is very important, so the addition of fluoride must be done in a liquid state.

R410's excellent thermodynamic properties allow the use of more compact compressors, and smaller diameter tubes, as it has lower energy losses. Refrigerant R410 is compatible with mineral oil or alkylbenzene oil because R410A will not mix with them.

The oil specified for refrigerant r410 is a polyol (POE) oil. These oils should not be exposed to the open air and should only be opened prior to use. Tools and parts must be refrigerator r410. Never use conventional gauges to charge refrigerant, measure pressure and watch them (burst tubes, gauges) just in case.
