Refrigeration & heat exchange
refrigeration
Industrial machinery; Refrigeration & heat exchange
Refrigeration is a process in which work is done to move heat from one location to another. This work is traditionally done by mechanical work, but can also be done by magnetism, laser or other ...
non-cyclic refrigeration
Industrial machinery; Refrigeration & heat exchange
In non-cyclic refrigeration, cooling is accomplished by melting ice or by subliming dry ice (frozen carbon dioxide). These methods are used for small-scale refrigeration such as in laboratories and ...
total loss refrigeration
Industrial machinery; Refrigeration & heat exchange
Refrigeration systems where the refrigerant evaporates and is vented to the atmosphere. Solid carbon dioxide has no liquid phase at normal atmospheric pressure, and sublimes directly from the solid ...
cyclic refrigeration
Industrial machinery; Refrigeration & heat exchange
This consists of a refrigeration cycle, where heat is removed from a low-temperature space or source and rejected to a high-temperature sink with the help of external work. A refrigeration cycle ...
thermodynamic power cycle
Industrial machinery; Refrigeration & heat exchange
A thermodynamic cycle consists of a series of thermodynamic processes transferring heat and work, while varying pressure, temperature, and other state variables, eventually returning a system to its ...
heat engine
Industrial machinery; Refrigeration & heat exchange
A heat engine is a system that performs the conversion of heat or thermal energy to mechanical work. It does this by bringing a working substance from a high temperature state to a lower temperature ...
vapor-compression cycle
Industrial machinery; Refrigeration & heat exchange
In this cycle, a circulating refrigerant such as Freon enters the compressor as a vapor. The vapor is compressed at constant entropy and exits the compressor as a vapor at a higher temperature, but ...
