R407A Pressure-Temperature Chart

R407A Pressure-Temperature Chart

Hello readers welcome to the new post. Here we will discuss the R407A Pressure-Temperature Chart. R407 A is gases mixture used as a refrigerant. It is an azeotropic blend of HFC32 or difluoromethane, pentafluoroethane, and 1,1,1,2-tetrafluoroethane (HFC-134a). It was made as a close configuration with R22 featues and flow rates, which makes it the best…

R422D Pressure Temperature Chart

R422D Pressure Temperature Chart

Here we will learn the R422D Pressure Temperature Chart. R422D refrigerant is a low-toxic, non-ozone-depleting hydrofluorocarbon (HFC)  used as a replacement of R22. It supported conventional and new lubricants, like mineral alkylbenzene (AB) and Polyester oils, mostly system retrofitting to R422D not needing to change the lubricant. This multiple-operation refrigerant operates in existing medium and low-temperature…
