What should the high and low pressures be for 404A refrigerant on a refrigerator?

18-20psig suction 250-270 psig discharge In freezers pressures are ok .I got it ,but the mention pressure of suction 18-20 discharge 250-270 at what temprature in centegrade it should be.

Mixing freon 22 with 404A would it work?

R-404a is a substitute for r-22 refrigerant but requires the system to be charged with POE lubricant. R-22 is being phased out by international protocols. The two refrigerents should not be mixed, but a tiny amount of residual r-22 left in a system being recharged with r-404a (which is itself a mixture of r-125, r-143a and r-134a) will not cause any problems.


What type of refrigerant do you need in a high temp walk in freezer?

Newer freezers compliant to efficiency standards use R-404a. However an older unit may only be able to us R-22 (which will be completely phased out by 2020).
