This is a table that tells you precisely what the pressure of R404A is at a certain temperature. At the low end, the pressure of 404A is 0.9 psig. At the high end, the pressure of 404A is 456.8 psig. We are, of course, talking about 404A liquid pressure.The pressure-temperature (PT) chart is a valuable tool that service technicians use to check proper system operation. PT charts are most often used for three purposes: to set a coil pressure so that the refrigerant produces the desired temperature, to check the amount of superheat above the saturated vapor condition at the outlet of the ...R-421A Refrigerant Facts & Info Sheet. June 9, 2022 by Brian Cole. R-421A is a highly efficient hydrofluorocarbon that is a drop-in replacement for R22 refrigerant. It consists of 2 components; that is, 58% of R-125 and 42% of R-134A.
