5. A/C INPUT/OUTPUT DIAGRAM
Below diagram shows the input/output mapping between the components of FATC A/C and A/C
controller briefly.
▶ A/C compressor control by engine ECU
In case of current vehicle models, the system turns ON or OFF the compressor switch according to the
refrigerant pressure, ambient temperature and condenser temperature to protect the A/C circuits.
However, for the vehicles equipped with DI engine, the engine ECU turns off the A/C compressor unde

below conditions, including those above.
Coolant temperature: 20℃ or less
Coolant temperature: 115℃ or more
For approx. 4 sec. after starting the engine
Engine speed: 650 rpm or less
Engine speed: 4,500 rpm or more

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