Want this question answered?
what is suction pressure of r407a
if room tem is 70f 15psi
if room tem is 70f 15psi
frezer not frezing hi side 250 psi low side 45 psi
No.
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.
No, refrigerants cannot be blended.
42
In a zeotropic blend, the blends boil out at different temperature but at the same pressure. typical example is R704

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.
a blended refrigerant with less than 10F temperature glide, 41oA and 404A are examples.
