Definitions:

Cold Material

A term that generally refers to material at a temperature significantly lower than the ambient or desired processing temperature.

Heat Exchanger

A device used to transfer heat between two or more fluids, gases, or solids of different temperatures without mixing them.

Condenser

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.
