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.
low 50 to 60 and high 250 to 300
42

what is suction pressure of r407a
No, refrigerants cannot be blended.
if room tem is 70f 15psi
if room tem is 70f 15psi
a blended refrigerant with less than 10F temperature glide, 41oA and 404A are examples.
In a zeotropic blend, the blends boil out at different temperature but at the same pressure. typical example is R704
frezer not frezing hi side 250 psi low side 45 psi
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.
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).
