Auto Air Conditioning Components

- to remove refrigerant from an A/C system and store it temporarily.

- any of the various designs of fittings that allow service tools such as manifold gauges to be attached to an A/C system.

Why must refrigerant be recovered from the A/C system before any A/C parts are replaced?

Which of these is NOT a refrigerant used in automotive A/C sytems?

a valve that controls the flow of refrigerant from a high pressure area to a low pressure area

- a chemical compound used in an A/C system to remove heat from the evaporator and transfer it to the condenser.

- a heat exchanger, in which low-pressure refrigerant flows and changes state, absorbing heat from the surrounding air and cools the passenger compartment.

a device, similar to a radiator, in which the refrigerant loses heat and changes state from a high-pressure gas to a high-pressure liquid as it dissipates heat to the surrounding air.

- an A/C system component into which high-pressure liquid refrigerant flows and is temporarily stored and dehydrated, usually located between the condenser outlet and expansion valve.

Which engine driven device compresses refrigerant gas and pumps it through the air conditioning system?
