Air Conditioning System's Structure Diagram and Fundamentals
Air Conditioning System Overview
Basic composition
Composed of air conditioner, compressor assembly, condenser
assembly, pipeline, defroster system, heating & ventilation
system, etc. The air conditioner also includes evaporator and
blower components.
Function
This system is a manually controlled air conditioning
system, with steam compression as its cooling method.
Residual heat water warming is the heating method the
engine adopts. Inner & outer circulation, blowing mode,
and cold & warm temperature adjustment are all controlled
by individual cables from the air conditioning controller. It
achieves ventilation, warming, and cooling integration.
Caution: While starting the compressor, you must open
the air regulation knob first, otherwise it cannot start.
Operation
The compressor is driven directly by the engine. High
temperature and high pressure refrigerant vapor exhausted
from the compressor will pass through the high pressure
pipe into the condenser, dissipate the heat via temperature
difference, and then form a high pressure liquid. High
pressure liquid passes through the accumulating dehydrator
into the expansion valve, and after passing through the
throttle valve, it becomes a low pressure liquid. Heat
exchange via the evaporator will cool down the room’s air,
and then the refrigerant inside the system will become a low
temperature and low pressure vapor, which is then sucked
into the compressor and compressed into high temperature
and high pressure air again. Thus a cooling cycle is formed.
The circulation continues, which maintains a comfortable
temperature inside the vehicle.

Rotary vane compressor’s operation
As the diagram shows, when the rotor is rotating under an
external force, due to the synergism of centrifugal force and the
oil pressure difference on the five vanes of the rotor, their edge
clings to the cylinder wall. Because the fixed cylinder is oval
shaped, while rotating on the rotor, the rotor vanes spread and
retract according to the cylinder's geometrical shape, which in
turn makes the crescent shape consisting of the cylinder, vanes,
etc. to change continuously, so as to achieve the functions of
suction, compression, and exhaustion.

Compressor Removal
1. Hoist the vehicle with a jack.
2. Remove the bottom mudguard.
3. Remove the compressor.
Compressor Installation
Before installing, manually rotate the compressor several
circles, allowing each component in the relative motion to be
covered with lubricant.
Clearance between the compressor's auricular branch and
bracket should be less than 0.1 mm. If the clearance is too
big, fill the clearance with a washer.
1. Loosen the engine's adjusting bolt firstly, take down the
engine belt, and then change the compressor belt.
2. Fix the compressor bracket onto the engine body with
the bolts. The bracket must be fastened tightly with suf-
ficient intensity. Fix the compressor bracket onto the
engine with four M10 ×1.25 (Q1461030 FD) bolts and
a tightening torque of 45±5 N·m, and then install the
compressor onto the bracket with a tightening torque of
22±3 N·m.
3. Ta k e o ff t h e s u c t i o n a n d e x h a u s t c a p . S e l e c t t h e
suction duct and exhaust duct that matches the size
of the suction and exhaust port to connect with each
other (size of suction and exhaust port shown in the
diagram). Then tighten the coupling bolt.

4. Put the 4PK850 type compressor belt onto the pulley,
and then adjust the bracket to make the belt reach the
specified tension. That is, if a force of 100-120 N is
used on the belt, deformation of the belt is 8-10 mm.
5. Insert the thermal protector plug into the relevant plug
of the air conditioning system's wire harness.

4. Separate installation for the front door lock assembly.
Separately install the front door lock, lock cable, unlock
cable, cable installing buckle, and side door inside handle
assembly. On the left is the schematic diagram after installa-
tion.
7. Install the inside handle.
Clamp the inside handle clip to the door inner decoration
board, and then firmly press the inside handle clip dowel pin
into the mounting hole.
8. Install the front door lock cylinder.
Clip the decorative cap of the driver side door onto the lock
cylinder, install the lock cylinder into the lock hole, and then
tighten the lock cylinder’s mounting screw.
5. Install the front door lock assembly.
Install the assembled assembly, tighten the lock mounting
screws (pay attention to put the outwardly opened tie rod in
and block the lock's outwardly opened swing arm lever clip
sheath), and insert the wire harness plug-in into door lock
socket.
6. Install the cable buckle.
Install the buckle in the door inner decoration board, and put
the cable in the buckle.
9. Install the door lock inside handle screws.
When the door cylinder panel assembly is installed, tighten
the inside handle's mounting screw.
