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??????????????


As I see it, virtually all the refrigerant would have had to leak out to
allow air to get into the system.

How low did the refrigerant level get?




Wouldn't the evap be in a vacuum at that temp or maybe a pump-down system?
