Subcooling Refrigeration Circuit

Refrigeration - Wikipedia, The Free Encyclopedia
Refrigeration is a process in which work is done to move heat from one location to another. The work of heat transport is traditionally driven by mechanical work, but can also be driven by heat, magnetism, electricity, laser, or other means. Refrigeration has many applications, including, but ... Read Article
