The difference of the refrigerant R22 and r410a purchasing refrigerants to know

with the phasing out of refrigerant R22, r410a refrigerant using range is more and more big, the refrigeration, many friends asked whether R22 directly replace r410a in dispatching system, which is unreasonable. Two kinds of refrigerant different physical and chemical parameters, the differences in system design, need to pay attention to. Let's take a look at what are the difference of the refrigerant R22 and R410A.

1, r410a refrigerant requires a synthetic refrigeration oil ( POE） , due to the high hygroscopicity, POE oil prone to hydrolysis, relative to R22, R410A system more strict with moisture moisture content.

2, perfusion after reducing heat exchanger structure, R410A system relative R22 perfusion to decrease about 20% ~ 30%. Bigger than R22, R410A system of total heat transfer characteristics of heat transfer efficiency is high, the heat exchanger can be miniaturized.

3, R410A for HFC - 32 ( R32） And HFC - 125 mixture refrigerant R410A for copper tube is more demanding, and R22 can use normal brass; R410A operation pressure is higher than R22 50 ~ 70%, about 1. 6 times.

4, R410A belongs to low toxicity, no combustion propagation, does not destroy the ozone layer, R22 is fatal for ozone destruction; R410A system refrigeration capacity, better if R22 refrigeration capacity 100%, R410A refrigeration capacity 147%;

5, even R410A does not destroy the ozone layer, but can produce greenhouse gases, the effect of greenhouse gases produced by the even greater than the R22. Therefore, R410A and not China air-conditioning environmental protection refrigerants solution. Ha ha, all those who say is environmental protection refrigerant R410A buddy, you can rest.

6 is larger than that of R22, R410A vapor density is big, so R410A steam flow rate compared with R22 slow about 30%; R410A is more soluble than R22. When particles floating in R410A, can smoothly circulate in the system.

the above introduction about the r410a refrigerant to the over here, hope to be able to bring you some help, if you have a demand on refrigerant r410a, welcome consultation discussion with us.
