Have you ever wondered how the refrigerators in your home work? Refrigerators, which have become an integral part of every household, work based on some simple and interesting scientific principles. Beginning with a basic refrigerator model, this video will elaborate on the operation of modern refrigerators, along with the secrets behind their high energy efficiency.
The term refrigeration means cooling a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature).In other words, refrigeration is artificial (human-made) cooling.Energy in the form of heat is removed from a low-temperature reservoir and transferred to a high-temperature reservoir.

The principle on how does a refrigerator work is pretty simple. Gases get hotter when you compress them into less volume because you have to work to push their energetic molecules together.
A refrigerator consists of several key components that play a crucial role in the cooling process:Expansion valve,Compressor,Evaporator,Condenser and Refrigerants also referred to as coolant, it is the liquid that keeps the refrigeration cycle going./ Lesics
