Air conditioner--Refrigerant
z The pressure of high and low
pressure end is low.
z The pipeline from condenser
to expansion valve frosts.
z Refrigerant flow in adjuster
is obstructed by impurity.
z Change the condenser.z Adjuster is obstructed.
Phenomenon Possible reason Diagnose Method
State: cooling degree is not enough
(4) Refrigerant cycle is poor
(5) Refrigerant does not have any cycle.
z Low pressure side is
vacuum, and pressure at
high pressure side is low.
z The pipeline of front and
rear end of expansion
valve or adjuster frosts or
dews.
z Refrigerant flow in cool-
ing system is obstructed
by water vapor or dust.
z Refrigerant flow is ob-
structed by expansion
valve.
(1)Check the expansion
valve.
(2)Remove the dirt in ex-
pansion valve with high
pressure air.
(3)Change condenser.
(4)Take out vacuum and fill
applicable refrigerant.
(5)If this is caused by ex-
pansion valve leakage,
change the valve.
Refrigerant does not flow.
Phenomenon Possible reason Diagnose Method
State: not cool (sometime cool)
