The cooling mechanism of a refrigerator is based on thermodynamic principles. The compressor compresses the refrigerant gas, increasing its pressure and temperature. Then, this gas releases its heat in the condenser, turning into a liquid. The liquid passes through the expansion valve, where its pressure drops and it begins to evaporate, absorbing heat from its surroundings in the process. This cools the inside of the refrigerator. The refrigerant then returns to the gas state and goes back to the compressor, and the cycle continues in this way. The thermostat controls the temperature, ensuring the compressor operates as needed.
