The system in question has a single condenser mounted indoors with a receiver. The system is using r134a. It has 2 air over evaporators with txv's.
clear sight glass
45 psi suction suction line at condenser 80 deg
140 psi discharge liquid line at condenser 103 deg
suction line at evap (1) 50 deg , suction at evap (2) 49 deg
liquid line at evap(1) 83 deg , Liquid line at evap (2) 85 deg
I assume there is a heat exchanger causing the temp difference from condenser to evaps.
I was called in mainly to find and fix leaks, which I did. I also cleaned the condenser.
I mainly do air conditioning and heating work, so I am puzzled why I cant get the cooler down to 45. Lowest it will go is 52 after 1 day operation.
