Air conditioner--Refrigerant
z
The pressure of high and
low pressure end is high.
z
There is no bubble on
window when engine
speed decreases.
z
Too much refrigerant in
system incurs this.
z
Heat dispersion of con-
denser is bad.
(1)Clean the condenser.
(2)Check the function of
cooling fan.
(3)If those two items above
are normal, check the re-
frigerant quantity. Fill
applicable refrigerant.
z
Filled refrigerant is too
much.
z
Heat dispersion of con-
denser is bad ¡ú ¡ú
¡ú ¡ú
¡ú
heat dis-
persion sheet of con-
denser is obstructed or fan
engine has malfunction.
Phenomenon Possible reason Diagnose Method
State: cooling degree is not enough.
z
The pressure of high and
low pressure end is high.
z
Pipeline of low pressure
end is too hot to contact.
z
T h e r e i s b u b b l e o n
window.
Air enters cooling system. (1)Check whether the Re-
frigerant oil is too dirt or
lack.
(2)Take our vacuum and fill
new refrigerant.
z
There is air in cooling
system.
z
I t d o e s n o t t a k e o u t
vacuum completely.
Phenomenon Possible reason Diagnose Method
State: cooling degree is not enough.
(6) Refrigerant is too much or the radiating fin of condenser is bad
(7) Air enters cooling system
Note: if cooling system is
opened, and it does not
take out vacuum when
filling refrigerant, this
state will happen.
