Refrigeration and Air Conditioning Technology (TUP-Visayas)

Refrigeration is a process in which work is done to remove heat from one location to another. Refrigeration has many applications including but not limited to; household refrigerators, industrial freezers, cryogenics, air conditioning, and heat pumps. In order to satisfy the Second Law of Thermodynamics, some form of work must be performed to accomplish this. The work is traditionally done by mechanical work but can also be done by magnetism, laser or other means.


Air conditioning is the removal of heat from indoor air for thermal comfort.
In another sense, the term can refer to any form of cooling, heating, ventilation, or disinfection that modifies the condition of air ..
