4. A/C COOLING CYCLE
(1) System flow
"Compression -> Condensation -> Expansion -> Evaporation"
-
(2) Functions
▶ Compressor
Condition: Gas
Function: Circulates the refrigerant and increases the pressure and temperature for easier
evaporation.
▶ Condenser
Condition: Gas/Liquid
Function: Cools and condenses the refrigerant by using ambient air to liquefy it under high
pressure.
Condition: Gas/Liquid
Function: Keeps the refrigerant free from moisture by separating/collecting the moisture from it. ▶ Receiver drier
▶ Expansion valve
Condition: Liquid/Liquefied gas
Function: Performs adiabatic expansion and flow control for easier evaporation.

▶ Evaporator
Condition: Liquefied gas/Gas
Function: Cools the air by absorbing the heat from the air around the evaporator.
(3) Description for Each Cycle
▶ Compression
The evaporated refrigerant in the evaporator enters to the compressor. And the refrigerant gas is
compressed until it can be liquefied at ambient temperature.
Thus, the low refrigerant pressure is maintained so that the liquid refrigerant can be evaporated
actively at low temperature (around 0℃). -
-
▶ Condensation
The high pressure and high temperature gas (refrigerant) from the compressor is cooled down by
the fresh air entered into the condenser. Then, this gas is converted to liquid and collected in the
receiver drier.
The heat generated from the high pressure refrigerant is dissipated to the ambient air, and it is
called "heat of condensation".
The heat of condensation is the summation of the heat of vaporization (heat that the refrigerant
absorbs from the inside of the vehicle) and the calorific value converted from the amount of work
which is needed to compress. -
-
▶ Expansion
The liquid refrigerant lowers the pressure making its evaporation easily accomplished.
This process (lowering the pressure to the level at which evaporation easily takes place before the
liquid refrigerant is sent to the evaporator) is called
"Adiabatic Expansion".
During adiabatic expansion, the expansion valve lowers the pressure of the refrigerant and
determines the correct amount of refrigerant going into the air conditioning evaporator.
That is, the amount of heat, which is needed to stop the evaporation, is determined according to the
cooling load.
The expansion valve detects this and regulates the amount of the refrigerant exactly. -
-
-
-
-
▶ Evaporator
The refrigerant is converted from liquid to gas in the evaporator.
(The refrigerant in the form of fog in the evaporator is vaporized actively)
At this time the refrigerant, in the form of liquid, absorbs the heat in the air which is need for
evaporation (latent heat) and is cooled down. Then the blower blows the cooled air inside the
vehicle to lower the temperature.
There are liquid refrigerant from the expansion valve and evaporated refrigerant in the evaporator.
The evaporation temperature can be predicted from the evaporation pressure (i.e. relationship
between saturation pressure and saturation temperature).
It is important to keep the pressure inside the evaporator low, so that the refrigerant is evaporated a
t
low temperature to make sure the completely evaporated refrigerant is entered into the
compressor. -

When a severe frontal impact occurs, seat belt
pre-tensioners rewind the seat belts
immediately to restrain the occupants to their
seats. It helps the effective operation of the
seat belts and airbags.

3) Warning for Air Bag
Do not diagnose the circuit with a circuit tester. Do not attempt to modify any air bag components
including the steering wheel, air bag mounting area, and harness.
Do not impact any air bag components including the steering wheel, air bag mounting area, and
harness by hand or tools. You may get injured by sudden deployment.
The air bag components will be very hot after deployment. Do not touch them.
Once the air bag system is triggered, the triggered air bag assembly should be removed from the
vehicle and replaced with new one.
The air bag contains explosive materials, so contact Ssangyong Dealer or Ssangyong Authorized
Service Operation when trashing or replacing it.
Incorrect air bag inspection can be dangerous and cause injuries. The air bag system must be
disposed only by Ssangyong Dealer or Ssangyong Authorized Service Operation.
Replace the steering wheel with only Ssangyong genuine part.
When the engine starts, the air bag warning lamp comes on for a system check. It goes out after 3
to 7 seconds when the system is normal. If this warning lamp stays ON, then the system may be
defective. Have the air bag system checked immediately by Ssangyong Dealer or Ssangyong
Authorized Service Operation.
The seat belt and air the bags are the most effective when you are sitting well back and upright in
the seat.
A child restraint system must not be placed on the front seat. The infant or child can be severely
injured by an air bag inflation in case of an accident.
Do not carry your child on your lap while driving. You cannot resist against the impact pressure in an
accident.
The child could be crushed between you and the parts of the vehicle.
Do not place any objects on the air bag inflation location. You may get injured by those objects
during deployment.
Do not attach any objects such as a sticker, scent bottle, or phone holder on the steering wheel pad
and to the dashboard. -

Do not put the seat cover on the front seatbacks. It may interfere with the side air bag inflation.
When sitting in the rear seat, do not hold onto the seatback of the front seat. If the side air bag
inflates, the occupant may get seriously injured.
Do not lean on the door. When the side air bag inflates, the occupant may get seriously injured.
Do not place any objects such as an umbrella or a bag between the side air bag and the door. Do not
place the part of your body near the side air bag. You may obstruct the side air bag or get injured by
the inflation impact.
Do not slam the front doors. It may lead to an unintended inflation of the side air bag.
Do not move your seat too close to the steering wheel or dashboard. If you lower your head, the air
bag can hit your head during inflation and can cause severe injury or even death.
Hold only the outer rim of the steering so that the air bag can inflate without any hindrances.
Do not place your face or chest near the steering wheel and dashboard. Also, do not allow anyone to
place their hands, leg or face on the dashboard. The air bag cannot work properly.
Do not hold and operate the steering wheel by crossing your arms. You could get seriously injured
when the air bag deploys.
When the air bag inflates, it makes a loud noise and smoke. However, the smoke is a non-toxic
nitrogen gas.
When the air bag is deployed, non-toxic gas will come out. This gas may cause skin, eyes or nose
irritation.
Wash it out with cold and clean water and consult the doctor if irritation continues.
When any repairs are needed for the steering wheel, or when an accident occurred without the air
bag deployment, have the air bag system checked by Ssangyong Dealer or Ssangyong Authorized
Service Operation.
The windshield glass may be broken when the passenger's air bag is deployed.
The air bag deployment can cause abrasion on your hands and face. -

3. CAUTIONS FOR POWER SEAT
You can operate the power seat with the ignition switch OFF. However, frequent operation of the
seat switch with the engine stopped can result in battery becoming discharged.
Operating more than one seat adjustment switch at the same time can cause damage to the seat
motor. Therefore, operate the seat switch only one at a time.
Do not use organic solvents such as benzene, thinner, alcohol or gasoline to prevent the seat
cover from being damaged while cleaning.
Do not operate the seat position adjustment switch forcefully when the seat does not move or it
contacts an object.
If the power seat is not operated, check and correct the problem before driving off. 1.
