Overhauling method
High temperature zone of condenser is
hotter than that in normal circumstance,
and normal temperature zone of con-
denser is hotter than that in normal cir-
cumstance.
Dirty surface of the con-
denser
Clean the surface of the con-
denser
1. There is too much condensed water
on surface of low pressure pipe, and
middle housing of condenser is not
hot or cold and even has condensed
water.
2. There are bubbles in sight glass.
Expansion valve has too
large opening degree or
is stuck in large opening
degree position by for-

1. The air intake hose joint of compres-
sor is under normal temperature or
warm.
2. The pointer of low pressure gauge
swings.
Compressor air suction
valve block is damaged
or cylinder body, piston or
piston ring leaks air due
to wear
Replace the compressor
1. The compressor exhaust pipe joint is
hotter than usual.
2. The pointer of high pressure gauge
