Mechanical refrigeration is accomplished by continuously circulating, evaporating, and condensing a fixed supply of refrigerant in a closed system. Evaporation occurs at a low temperature and low ...

Scientists at Lawrence Berkeley National Laboratory have developed a novel potential means of alternative refrigeration: ionocaloric cooling. The method involves electrically charged atoms or ...

Seeking to make cooling more climate friendly and efficient, researchers used an environmentally-benign solvent and a salt – versus hydrofluorocarbons or other liquid refrigerants – to present a new ...

When troubleshooting a refrigeration system, it is important to understand how the refrigeration cycle accomplishes the goal of removing heat from a room and rejecting the heat absorbed by the ...
