Air Conditioning Components

An evaporator

• controls the amount of refrigerant released into the evaporator.

• turns the liquid form of a chemical substance such as water into its gaseous-form/vapor.

• increases the pressure of a gas by reducing its volume.

• transfers heat between two or more fluids.

A compressor

• controls the amount of refrigerant released into the evaporator.

• turns the liquid form of a chemical substance such as water into its gaseous-form/vapor.

• increases the pressure of a gas by reducing its volume.

• transfers heat between two or more fluids.
