How does car air conditioning work?
Your car air-conditioning system is made up of six parts:
- Evaporation coils
- Thermal expansion valve
- Refrigerant (gas)
When your air conditioner is switched on, the gas from the refrigerant travels to the condenser – this way, fresh air from the environment passes over the condenser. This causes the temperature of the gas to cool and become a liquid.
The liquid then passes through the receiver, which cleanses the impurities before reaching the thermal expansion valve. The valve allows you to adjust the temperature through altering the flow of the liquid – this is then turned to vapour whilst it passes through the evaporation coils. From this vapour, cool air gets blown into the cabin of your car.
