A refrigerator doesn’t make cold—it removes heat from inside and dumps it into your room. A special fluid called refrigerant circulates in a loop. The compressor squeezes it into a hot, high‑pressure gas. Outside coils—the condenser—release that heat to the air and the refrigerant becomes a liquid. Then it passes through a tiny expansion tube or valve, dropping in pressure and getting very cold. Inside coils—the evaporator—absorb heat from the food air, and the cycle repeats.
