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.

4.Pressure Relief Valve 5.Expansion Valve 6.Evaporator 7.Blower
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

314Have a focus inspection on the following area:
a. Each pipe union joint and valve connection.
b. All hose, especially near the pipe union.
c. Compressor shaft seal, front and rear cover, gasket, oil fill plug.
d. Area on the surface of the condenser and evaporator that is scratched, bruised or damaged.
e. Expansion valve inlet and outlet connection and temperature sensor element and the welding position.
3. Check the Refrigerant
Observing from the sight glass, you may understand the refrigerant status and analyze the possible faults:

369Chapter 2 Body RepairSection 1 Body Damage Forms and Requirements for RepairI. Body Damage FormsThe body damage forms are deformation caused by crash, overload, fatigue and corrosion, and tearing,
rusting, water & dust leaking.
The damage of the body is caused not only by overload, also by being often in an abnormal operating status
when the door or other parts are damaged. However, at most times, accidents like crash and turnover result
in bending and torsioning deflection because of the great overload on partial areas.
General conditions of the body damage are as follows:
1. The Front Central Is Crashed (Figure 5-13)
Figure 5-13 The Front Central Is Crashed
Because the front central is damaged by outside force, the left and right hood is usually stretched inwards;
therefore, the following are the key places to inspect.
1Nearby the left and right mounting place of the hood;
2Nearby the left and right mounting connection place of the front cross member.
