Clean the strainer screen by dipping it in an approved solvent and then allow it to dry. Replace the strainer and evacuate the air from the compressor. Test the housing for leaks by wiping up all oil and then using a halide leak detector. The compressor discharge line terminates at the refrigerant condenser. The tubes are expanded into grooved holes in the tube sheet so as to make an absolutely tight joint between the shell and the circulating water.
Refrigerant vapor is admitted to the shell, and condenses on the outer surfaces of the tubes.
Any air or noncondensable gases which may accidentally enter the refrigeration system is drawn through the piping and eventually discharged into the condenser with the R-12 gas. The air or noncondensable gases accumulated in the condenser are lighter than the refrigerant gas and rise to the top of the condenser when the plant is shut down.
