3. COMPONENTS AND FUNCTION

3.1. Compressor: Converts low-pressure gas to high-pressure gas

3.2. Condenser: Releases heat, transforms gas into liquid.

3.3. Expansion Valve: Lowers pressure and temperature.

3.4. Evaporator: Absorbs heat, cools and dries cabin air.

3.5. Blower Fan: Distributes cooled air.

3.6. Control Panel and Sensors: Set preferences and monitor conditions.

3.7. Control Unit (ECU): Adjusts system based on inputs.

3.8. Blend Doors: Regulate air mixture.

3.9. Cabin Air Filter: Improves air quality.
