4. A/C COOLING CYCLE

1) Basic Operating Principle

(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.
▶ Receiver drier
Condition: Gas/Liquid
Function: Keeps the refrigerant free from moisture by separating/collecting the moisture from it.
▶ Expansion valve
Condition: Liquid/Liquefied gas
Function: Performs adiabatic expansion and flow control for easier evaporation.
