Refrigeration is a process in which work is done to move heat from a low temperature to a high temperature and typically also 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 can be used for a variety of purposes:
- refrigerating food
- cooling spaces
Technical
Terms associated with refrigeration:
- coefficient of performance or COP is a measurement of the energy efficiency of a refrigeration (or heat pump) system.
COP for refrigeration is calculated as: Cooling effect/Work input, or COPR= QL/Wnet,in where QL is the desired energy into the low temperature environment and Wnet,in is the required work input into the refrigerator itself.
