How a Refrigerator Works — Simple, Visual, and Animated

How a Refrigerator Works — Simple, Visual, and Animated A refrigerator keeps food cold by removing heat from the interior and expelling it outside. This happens continuously through a closed loop called the refrigeration cycle , which uses a refrigerant (a fluid that evaporates and condenses easily) and four main components: compressor , condenser , expansion device , and evaporator . Below is an easy step-by-step explanation plus an animated diagram you can watch to understand the flow. Compressor Sucks in refrigerant vapour C Condenser Releases heat; vapour → liquid Expansion Pressure drop → cold liquid Evaporator (inside) Absorbs heat → liquid evaporates 1. Low-pressure cold vapour 2. Compressed hot vapour 3. High-pressure liquid 4. Low-pressure cold liquid → Evaporates inside Quick Animation Recap: Compressor raises pressure & temperature → Condenser rejects heat and condenses the refrigerant → Expansion device drops pressure (liquid gets very cold) → Evaporator absorbs interior heat and e…
