How does your fridge keep food cold without making cold? It moves heat. A cooling fluid circulates in a closed loop, carrying heat from the compartment you open every day out into the kitchen. Inside, the evaporator-the part that absorbs heat-takes warmth from the fridge. The fluid then reaches the compressor, which squeezes it, raising its pressure and temperature. It doesn't make cold; it drives the heat-moving cycle. Next, the condenser releases that heat into the room. It may be hidden in the cabinet or sit at the back or bottom. Then an expansion device lowers the fluid's pressure, cooling it before it returns inside to absorb more heat. And around it goes: heat leaves the fridge, while the fluid starts its trip again. So your fridge keeps food cold by carrying warmth from inside and letting it go into the kitchen.
