An electrical charge storage device also known as a capacitor. In an A/C circuit, it is a heat exchanger located in the vehicle airflow and subject to the ram air. Cooling of the refrigerant causes it to condense to a liquid state. This results in the refrigerant changing to a liquid state.
Thermodynamics
A branch of physics that deals with the behavior of heat; its principles are used to explain the operation of heat exchangers and A/C operation.
Behavior of Heat
The study of how heat energy transfers between materials or systems and its effects.
