Best Vacuum Pump For Auto Ac Buying Guides

How a Vacuum Pump Works in an AC System

A vacuum pump is used to remove air and other gases from an closed system. A typical automotive air conditioning system has a refrigerant that is under high pressure. The pressure in the system needs to be relieved in order for the refrigerant to be released and turned into a liquid.

The vacuum pump is used to remove the air from the system so that the refrigerant can be turned into a liquid. The pump is also used to remove any moisture from the system.

The Different Types of Vacuum Pumps

The main types of vacuum pumps used in automotive air conditioning are reciprocating, rotary vane, and scroll.

Reciprocating pumps are the most common type of vacuum pump used in automotive air conditioning. They work by using a piston to create a vacuum. The piston is connected to a crankshaft, which is turned by an electric motor.

The piston moves up and down in a cylinder, which is filled with a gas such as nitrogen. When the piston moves up, the gas is compressed and creates a vacuum. When the piston moves down, the gas expands and pushes the air out of the cylinder.

Rotary vane pumps work in a similar way to reciprocating pumps, but instead of a piston, they use a vaned rotor. The rotor is turned by an electric motor, and the vanes create a vacuum as they move around the rotor.

Scroll pumps are a type of positive displacement pump. They use two scroll-shaped plates, which are connected to an electric motor. The plates move in a spiral motion, and as they do, they trap pockets of air.

These pockets of air are compressed and create a vacuum.
