The contrast of refrigerant R410A and R22

by:Arkool     2020-03-16
< p> in an era of advocating energy conservation and environmental protection, air source heat pump as alternatives to traditional heating refrigeration products of new type of energy conservation and environmental protection products. There are many types of air source heat pump refrigerant, today, we introduce the contrast of the two refrigerant R22 and R410A results. < / p> < p> < / p> < p> R410A refrigerant composed of two kinds of quasi azeotropic mixture, mainly include hydrogen, fluorine and carbon element, has a stable, non-toxic, superior performance, etc. At the same time as a result of not containing chlorine, so will not react with ozone, won't destroy the ozone layer. R410A refrigerant as a new environmental protection refrigerants, compared with other cold media products, more environmentally friendly and energy saving, refrigerant is more efficient. < / p> < p> < / p> < p> refrigerant R410A and R22 contrast < / p> < p> 1, R410A refrigerant generally requires a polyol ester ( POE) Frozen oil, due to the high hygroscopicity, POE oil prone to hydrolysis, relative to R22, R410A affinity than mineral oil with good affinity with R22, traditional effective lubrication compressor and other moving parts, reduce wear to extend the service life. At the same time, R410A compressor running noise ratio significantly lower 2 - R22 compressor 4 db. < / p> < p> 2, R410A air-conditioning system pressure is 1 of R22. 6 times, the solvent unit refrigerating capacity 40% higher than that of R22. Bigger than R22, R410A system of total heat transfer characteristics of high heat transfer efficiency, small pressure loss, the compressor can be miniaturized, load ability is stronger, more quiet operation. < / p> < p> 3, by contrast, R410A endothermic and exothermic efficiency is greater than R22, R410A compressor collective working temperature will be lower, exhaust temperature will be much lower, it will reduce the compressor because the risk of overheating and burning. < / p> < p> 4, R410A belongs to low toxicity, no combustion propagation, does not destroy the ozone layer. R22 is deadly for ozone destructive; The refrigerant R410A system refrigeration capacity better, R410A system eer ( COP) Can be better than 6% higher than that of R22. And more environmentally friendly, is conducive to protect the ozone layer, more in line with the requirements of society for environmental protection. < / p> < p> < / p> < p> as refrigerant R410A as today's widely used in high temperature, is mainly used in household air conditioner, small and medium-sized commercial air conditioning mobile air-conditioning, dehumidifier, industrial refrigeration refrigeration equipment, etc. Environmental refrigerant R410A is by far the most appropriate internationally recognized to replace R22 of refrigerant, and in Europe and the United States, Japan and other countries. < / p> < p> < / p>
