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.
