An aftercooler removes heat from the compressed air coming from a supercharger before it enters an engine's induction system. This increases efficiency and power by increasing the density of the air, making for more air ... More »

When air is compressed rapidly, temperature increases because temperature and volume of gas are inversely proportional to each other according to gas laws. When air is compressed rapidly, its volume decreases leading to ... More »

A radiator overflow tank collects the expanding coolant that is heated by the engine and recycles it back into the coolant system once it loses enough heat. The radiator overflow tank works in conjunction with the radiat... More »

The condenser on a refrigerator removes heat from a gas coolant and condenses it into high-pressure liquid. Coolant evaporates at low temperatures and low pressure but condenses at high temperature and high pressure; bec... More »

A freezer and fridge work the same way by using a refrigerant to move heat from inside the unit to the outside. In combination units, air from the freezer is used to cool the refrigerator compartment. More »

Consul liquefied petroleum gas refrigerators work using the ammonia absorption cooling process to remove heat from an insulated box. This refrigeration process dates to Michael Faraday in 1924 and is older than evaporati... More » Home & Garden Appliances Refrigerators & Freezers
