Automotive Ac System Flow

All automotive air conditioning systems are nearly closed loops with a high pressure side and low pressure side.

Automotive ac system flow.

Your vehicle s compressor powered by the serpentine belt compresses the refrigerant into a liquid putting it into a high pressure state. Although this system works fantastic on modern vehicles it was not so reliable on the mid 90s vehicles. The compressor is a pump driven by a belt attached to the engine s crankshaft. An example of one of the most troublesome ones is pictured to the right.

How does a car s air conditioning work. Classic auto air engineers have been using their multi faceted knowledge of classic car air conditioning to design the most high performance model specific a c kits available since 1977. System pressure chart get a quick look at what an average a c system looks like along with the compressor manufacturer and what the specific r 134a requirements are for your car. The restoration trade and classic car enthusiasts widely consider classic auto air to have the highest quality products in the industry.

When the refrigerant is drawn into the compressor it is in a low pressure gaseous form. The diagram shows the flow of r 134a freon in an automotive air conditioning system. The freon is compressed and flows through the condenser where it is cooled into a liquid. Vacuum diagrams of air conditioning system can be found in online car repair manuals.

The freon passes through the receiver dryer to remove moisture. The electric motor system first started to appear in the mid 90s on gm cars and trucks.
