Freezer Refrigeration Principle

Vaporization (liquid to gas) is the absorbed heat; liquefaction (steam into water) is the heat, whether it is a refrigerator or air conditioning is the same works as follows

(Low temperature low voltage) refrigeration agent (gas) → compressor → (liquefied) liquid of refrigeration agent (high temperature high pressure) → thermal device (Refrigerator of surface put heat out) → liquid of refrigeration agent (low temperature high pressure) → capillary → refrigerator within of evaporator (around in box within wall of copper tube) gasification is endothermic → refrigerator within of temperature on will declined → (gasification) refrigeration agent (low temperature low voltage) → compressor

Just from the complex cycling of heat to the refrigerant inside the box is moved out of the medium.
