One time when I was on a boat to China, I had the job of baby sitting
the refrigerated container vans. One of the 'reefers' developed a leak
in the evaporater. Since the set point was -13F and the refrigerant
was R134a air leaked into the evaporater. Then the air migrated into
the condenser and caused a reduction in cooling ability and high
discharge pressure. Now here is the part I don't understand. What the
'reason' why the air migrated into the condenser??????????????

it doesn't migrate there it gets pumped by the compressor and due to the
nature of non condensables air gets trapped as it can't condense and flow
out of the liq line

I know it can't condense, but why doesnt't it flow. Because the air
is now separated from the refrigerant? Shouldn't liquid refrigerant
still be able push the air along the liquid line.
