How does car air con work in a car?

Typically, car air conditioning works the same in all vehicles - the air conditioning system runs on a high-pressure gas called refrigerant. Regardless of what make or model your vehicle is, the air conditioning system will use the same components and parts in order to work efficiently.

Air conditioning system parts

Compressor: this feature compresses the refrigerant into a fluid, which means that the refrigerant is able to flow through a line to the condenser.

Condenser: the condenser removes the heat from the refrigerant, while pushing it along to the expansion valve/orifice tube.

Expansion valve/orifice tube: this feature returns the refrigerant to its original gaseous state. It then moves the refrigerant over to the receiver/drier or accumulator.

Receiver/drier or accumulator: this feature removes the moisture from the refrigerant, while transferring it to the evaporator.

Evaporator: the evaporator transfers heat from the air passing through its core into the refrigerant. This process results in cold air flowing beyond the evaporator.

Does air con affect your fuel efficiency?

By using your air conditioning regularly, this is likely to have an effect on your fuel consumption. Research suggests that by using your air conditioning system in your vehicle, this can actually increase your petrol usage by around 8-10%.
