Answers
Cooling is removal of heat, usually resulting in a lower temperature and/or phase change. Temperature lowering achieved by any other means may also be called cooling. The transfer of thermal energy may occur via thermal radiation, heat conduction or convection.
REFRIGERATION
In simple words, the cooling or removal of heat from a system is called as refrigeration.
KEY TAKEAWAYS FOR REFRIGERATION:
* The phrase refrigeration refers to the process of chilling an area, material, or system in order to decrease and/or keep its temperature below that of the surrounding environment (while the removed heat is rejected at a higher temperature).
* Refrigeration, in other terms, is a type of artificial (human-made) cooling. Energy is transported from a low-temperature reservoir to a high-temperature reservoir in the form of heat. Energy transfer work is generally powered by mechanical methods, but it may also be powered by heat, magnetism, electricity, lasers, or other technologies.
* Household refrigerators, industrial freezers, cryogenics, and air conditioning are all examples of refrigeration. Heat pumps are similar to air conditioners in that they employ the heat output of the refrigeration process and may also be engineered to be reversible.
