Dear Friends,

I have a shop at my country and I sell refrigeration parts at my country by this I should be able to inform and lead my customers.

During a year, two of my customers called me and they had this problem :

They told me their system charged with R22, They check discharge pressure, Pressure was 270 ~ 290 PSI but discharge pipe was not hot and they could able to touch it by their hand.
Also sight glass was full but they complained cold room temperature didn't go down and didn't go less than for example -5C but they wanted for example temp. -18C.

What do you think about this ? What kind of problem you think was on these systems that made this situation ? Discharge pressure is high on R22 but discharge pipe temperature not be hot ?!

Sincerely yours.
