compressor, condenser and evaporator etc, it adsorbs heat in the air through circulation of refrigerant, so as to
reduce air temperature in car body and eliminate water vapour in air, to achieve the purpose of temperature drop
and dehumidification. Heating system mainly consists of heat exchanger and heater unit. It utilizes heat of engine
cooling water to heat air via heat exchanger, so as to achieve the purpose of heating. Regulation and control of
temperature, humidity and flow rate of air in car body is realized via heating and refrigeration systems separately
or jointly.
For parameters of refrigerating system, see the table:

General Information

5-73Precautions:1. Don't operate refrigerant in confined space or near open fire.
2. Always wear eyeglass.
3. Be careful don't let liquid refrigerant contact your eyes and skin,
if liquid refrigerant contacts your eye or skin.
(a) Please wash with fresh water.
Warning:
Don't knead your eyes or scrub your skin
(b) Apply soft petroleum ointment on your skin.
(c) See doctor or go to hospital immediately for specialized
treatment.
4. Don't heat container or put it near open fire.
5. Be careful not to fall off, object should not touch container.
6. If there is no sufficient refrigerant in refrigerating system, don't
operate the compressor.
If there is no sufficient refrigerant in the system, insufficient oil
lubrication might cause burning out of compressor. Be careful to
avoid occurrence of such things.
7. When compressor runs, don't turn on pressure gauge high-pressure
valve.
If high-pressure valve is turned on, refrigerant will flow in reverse
direction, and cause bursting of refrigerant tank, so only low
pressure valve may be turned on or off.
8. Be careful to avoid excess refrigerant
Excess refrigerant will result in poor refrigerating capacity, worse
fuel economical efficiency, engine overheat etc problems.Symptom

(a) Magnetic clutch control:
Check operation of pressure switch
( 1 ) Install manifold instrument
( 2 ) Connect positive meter pen of ohmmeter to terminal 4,
negative meter pen to terminal 1respectively.
( 3 ) As shown in the figure, check connection of each terminal
when refrigerant pressure changes
If operation does not conform to specification, replace
pressure switch.
(b) Check operation of condenser fan
( 1 ) Connect positive meter pen to terminal 2, negative meter pen to terminal 3 respectively.
( 2 ) As shown in the figure, check connection of each terminal when refrigerant pressure changes
If operation does not conform to specification, replace pressure switch.
2. Compressor magnetic clutch
(a) Connect positive pole of storage battery to binding post, negative pole to compressor shell.
(b) Check magnetic clutch in energized condition.
If abnormal, replace magnetic clutch.
