2. Without cold airInside sealing of compressor
is poorCompressor fails, valve
leaks or is damaged.Repair or replace
compressorCompressor failure (9) Compressor poor compression faultDischarge and fill-up of refrigerantDischarge of refrigerant
In case of depletion, surrounding environment should always be
well-ventilated, do not approach open fire, otherwise toxic gas might
be generated.
(1) Firstly turn off meter valve high low manual valve, connect
pipeline according to the figure below, then adjust air conditioner to
maximum refrigeration operating condition, adjust engine speed to
1000 - 2000 r/min, run for 5 min. Circulate refrigerant and collect
residual oil in parts as far as possible into compressor.Symptom Possible cause Diagnosis Correct treatment (2) Loosen throttle, let engine restore to normal idle speed, turn off engine.
(3) Slowly open high voltage manual valve,cover a white towel on hose outlet,observe whether there is oil stain
on the towel, adjust flow of refrigerant.
(4) When high pressure gauge reading decreases to below 0. 35MPa, slowly open low pressure manual valve.
Close manual valve until reading of high low pressure gauge is zero.Fill-up of refrigerant (1) Use vacuum pump to vacuumize the system
During repair of refrigerating system, once refrigerating system is exposed to air or certain refrigerating
system part is to be replaced, automobile air conditioner must be vacuumized. So as to eliminate air and
water vapour in the system.
