Dx Refrigeration Cycle

Carnot cycle - Wikipedia, The Free Encyclopedia
The Carnot cycle is a theoretical thermodynamic cycle proposed by Nicolas Léonard Sadi Carnot in 1823 and expanded by in the 1830s and 40s. It can be shown that it is the most efficient cycle for converting a given amount of thermal energy into work, or conversely, creating a temperature ... Read Article
