Carbon dioxide (CO

The process of a solid changing directly into a vapor.

A simple device that provides cold air by separating it from hot air.

A thermostatic expansion valve (TXV) that operates based on discharge line temperature and acts as a liquid injection valve from the liquid line to the suction line in truck and trailer refrigeration systems.

Several thermoelectric couples connected in series to produce a greater thermoelectric refrigeration effect.

A closed thermodynamic cycle that can convert thermal energy into mechanical energy and vice versa.

In marine HVACR, a condenser located on the outer hull of a boat near the keel to take advantage of water’s ability to absorb heat

A junction formed by one N-type material and one P-type material that uses the Peltier effect to produce thermoelectric refrigeration.

The process of transferring heat energy from one place to another using the movement of electrons, based on the Peltier effect.

A phenomenon that occurs when current is passed through the junction of two dissimilar metals, causing heat to be absorbed in one part of the junction and moved to another part of the junction. It is the basis of modern thermoelectric refrigeration.

A thin, rectangular tank containing an evaporator surrounded by a solution that freezes at a desired temperature. Primarily used in truck or trailer refrigeration.

When a refrigerated trailer's refrigeration system is plugged into the electrical grid while the trailer is idle.

a cooling system that uses waste heat to help pressurize refrigerant and drive it form the evaporator to the condenser
