Putting R410a into a system designed for R22 would be like putting rocket fuel in a car—not recommended. I have never seen one so low on 410A and charged to manufacturers guidelines, there was frosting on suction valve and inlet/outlets to evap after a couple of minutes. Pressured speech is when you talk in a fast, fran. 6 times) greater than R-22. A R-410A evaporator running below 100 psig will freeze-up just like its R-22 cousin. logitech farming simulator Here we will make an R410A Pressure-Temperature Chart that will help you find its working for different temperature ranges The liquid pressure should be 385-395 and the suction pressure should be about 138 but will probably be a few psi lower since it's so cool in the space. , T/F: R-410A is a drop in replacement for R-22 and more. 2 psia, according to the Table 8 (ASHRAE, 2013).
