The Science Behind Refrigeration: How It Works

Understanding the basic principles of how a refrigerator works can provide a deeper appreciation for its capabilities. The refrigeration cycle involves the circulation of a refrigerant, a substance that absorbs and releases heat as it changes state.

The Refrigeration Cycle

The refrigeration cycle consists of four main components: the compressor, the condenser, the expansion valve, and the evaporator. The compressor compresses the refrigerant, increasing its temperature and pressure. The hot, high-pressure refrigerant then flows to the condenser, where it releases heat to the surroundings and condenses into a liquid. The liquid refrigerant then passes through the expansion valve, which reduces its pressure and temperature. Finally, the cold, low-pressure refrigerant enters the evaporator, where it absorbs heat from the inside of the refrigerator, cooling the air. The refrigerant then returns to the compressor, and the cycle repeats.

Refrigerants: Past, Present, and Future

The type of refrigerant used in refrigerators has evolved over time. Early refrigerators used refrigerants such as ammonia and sulfur dioxide, which were toxic and flammable. Modern refrigerators typically use refrigerants such as R-134a and R-600a, which are safer and more environmentally friendly.
