297Part IV Air Conditioner and Inside &
Outside TrimChapter 1 A/C SystemA/C system consists of refrigerating and heating system. The Refrigeration system mainly comprises
compressor, condenser and evaporator. The refrigerant circulation absorbs the heat in the air and discharge
the vapour to lower the temperature in and dehumidify the compartment. The heating system is mainly
composed of heat exchanger and heater. It heats the compartment throught the heat exchanger by heating
the air with the heat from the cooling water in the engine. The control of air temperature, humidity and
velocity of flow in the compartment is realized by independent or joint working of heating and Refrigeration
system.Section 1 The Structure & Working Principle of Refrigeration SystemThe structure of Refrigeration system is shown in Figure 1.

Refrigeration system uses vapor compressing refrigeration cycle, comprising the compressor, condenser,
pressure relief valve, evaporator, blower , expansion valve, receiver/drier and pipe.
It's working principle is as shown in the Figure 1. The compressor (1) sucks in the refrigerant gas in the

299Section 2 Heating SystemHeating system uses mixed temperature adjustment which controls both cold and hot air and is featured in
outstanding temperature adjustment performance. The cold and hot air can be completely mixed at each
outlet and achieve continuous temperature adjustment. The air duct arrangement on the instrument panel is
shown in Figure 2. The air flow channel system is shown in Figure 3.I. Heating System Parameter and StructureHeating system uses water heating structure which uses the engine coolant as the heat source, leads the the
coolant into the heating radiator installed in the vehicle compartment and has the interior or exterior air blow
across the radiator with the blower to increase its temperature. The system consists of the blower assembly,
heating control assembly and heater assembly.Figure 2 Heating Duct ArrangementInside and Outside Air Switch Door Outdoor AirIndoor AirDefoggerIntermidiate outletHeaterBlower MotorEvaporatorAir Mix DoorHeating RadiatorFigure 3 Air Flow Channel System Illustration

Heating System Parameter
2. Blower
Blower is located at the lower part of the goods
compartment. The door inside the blower case is con-
trolled by the servomotor. The exchange of the air in-
side and outside the door can be achieved by adjusting
the door to import the outdoor air and recirculate the
indoor air.
Blower motor uses Permenant magnet DC motor with multple blade fan. In addition, there are a set of
resistance on the blower which adjust the fan, called as adjusting resistor. Blower provides wind supply not
only to the heating radiator, but also to the evaporator in the refrigeration system.
3. A/C Control Mechanism
A/C control mechanism is located in the middle of the instrument panel. All adjustment except the A/C switch
and inside and outside circulation switch are made by rotating the control knob. The A/C control panel is
shown in Figure 4.
1Temperature adjustment control knob: control the mix ratio of the cold and hot air by adjusting the air mix
door, use the control knob to achieve continuous temperature adjustment.
2Outlet control knob: use 4 ranges, different types of air flow adjustment available.
3Inside and outside circulation switch: It can toggles between the introduction of outdoor air and recirculation
of the indoor air. (press the switch for inside circulation)
4Blower switch: when the plum blossom range is closed, the remaining four ranges are used to adjust the
air flow.
5A/C switch: as the switch of the refrigeration system, use press-button with built-in A/C indicator.Dissipation Power/W 4000

The heater comprises the heater radiator (heat exchanger), the plastic case forming the air duct, connecting
rods adjusting different air ducts and the door. The two groups of combination doors in the heater case are
connected to the heating control mechanism by the cable. The first group is the two couple action doors
adjusting the air mix ratio that are located in the outlet and inlet each; the second group comprises 4 doors
controlling the air outlet vents, where the upper center one controls the front outlet vent, each of the upper
left and right sides controls a defogger outlet vent and lower foot outlet vent. Figure 5 shows the working
principle of temperature adjustment door. The d) , c) , e) , f) in the figure indicate the outlet air flow direction

304Section 4 Service Caution & NoticeI. Service CautionRefrigerant Treatment
•During the treatment, the operator shall be careful not to inhale A/C refrigerant or lubricant vapor. Long-
term exposure to the A/C environment will cause the operator's eye, nose and throat liable to stimulation.
In addition, based on the consideration on the environment influence, when discharging the HFC-134a
from the A/C system, we suggest using the recyclable and rechargeable devices. If sudden system fault
occurs, it is recommended to place the device on a ventilated place before starting service.
•For HFC-134a service equipment, it is recommended not to perform the pressurization check or leakage
inspection. If these mixture combust, it may result in severe human injury or property loss.
•Please be noticed not to let the refrigerant leak near the spark or other hot objects. If the refrigerant gas
contacts the spark or similar heat source (e.g. cigarette or heater), it may generate poisonous gas. The
refrigerant is extremely liable to leakage during the transportation. In this case, please eliminate or remove
the heat source mentioned above and keep good ventilation.
•It is very dangerous to handle the liquid refrigerant. Only a drop of refrigerant can result in local frostbite
on skin if dropped on the skin of the operator. Therefore, it is specified that the operator shall always
wear glove and eye protection during the handling of the liquid refrigerant. If liquid refrigerant gets in
your eyes or on your skin, Wash the area with much cool water. Go immediately to hospital for professional
treatment.
Refrigerant Preservation
• Refrigerant preservation container is a high pressure resistant equipment. If it is put in hot treatment, the
explosion may arise, and the resulting metal fragments and the splashed liquid refrigerant will result in
severe human injury. It is recommended to preserve the refrigerant below 40°C.II. Service NoticeInsufficient Refrigerant Handling
•If the refrigerant is founded to be insufficient during the fault diagnosis, it is recommended not to add
refrigerant because of the following facts: the pressure readings indicated by different pressure gauge
are different, thus you will be unable to determine the exact amount of the refrigerant to be added, and
excessive or insufficient refrigerant may cause a series of chained negative effects such as damaged
refrigerant circulation parts or deteriorated refrigeration effect. Therefore, if the refrigerant is found to
be insufficient, it is recommended to drain the refrigerant from the refrigerant circulation pipeline and fill
specified amount of the refrigerant.
Compressor Oil Handling
•For this type of vehicle, it is recommended to use SW-100 type compressor oil. Use of PAG compressor
oil other than the SW-100 type may cause the A/C compressor to be damaged.
•During the operation, please be noticed not to splash the SW-100 type compressor oil onto the vehicle
surface. Therefore, if this happens, please wipe it off immediately, otherwise the compressor oil will
damage the paint on the vehicle surface.
