3) Description for Each Cycle
(1) 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 ℃). -
-
(2) 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. -
-
(3) 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. -
-
(4) 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 at
low temperature to make sure the completely evaporated refrigerant is entered into the compressor. -

1. CAUTIONS FOR AIR BAG OPERATION
When there is any deployed air bag (including seat belt pretensioner), the air bag unit should be
replaced. Any DTC (Diagnostic Trouble Code) in the air bag unit should not be cleared since the
unit has data for status when the air bag was deployed as well as information related to the air bag
deployment.
Note that the used components related to the air bag, especially the air bag unit, should be
packaged in an air tight container to prevent any damage.
Do not connect a tester to any connector or component to check supply voltage or resistance of ai
r
bag related components. The detonator may explode due to a sudden extra power supplied by the
tester.
Before removing or installing any air bag related components, disconnect the negative battery
cable. 1.

Collision sensors, a kind of impact G (acceleration) sensor, detect the lateral and longitudinal collisions
and determine whether or not to deploy air bags. The roles of each collision sensor are as follows:
Front G sensors (inside the air bag unit)
Send signals to the front air bags (driver and passenger air bags) and the driver's and front
passenger's seat belt pretensioners. When the front collision G sensor sends out only the air bag
deployment signal, the signal deploys the two front air bags and activates their seat belt
pretensioners.
Once an air bag deploys, its repair parts vary according to the deployment situation and damage to the
vehicle from collision. Needed repairs also slightly vary between the front air bags and the curtain air
bags. The following are the differences:
Replacement parts when the front air bags deploy:
Air bag unit and its wiring (including connector), seat belt pretensioner and its wiring (including
connector), whole front air bags, instrument panel (IP)
