👉 Fridge engineering involves the intricate design and optimization of refrigeration systems to efficiently maintain low temperatures for food preservation while ensuring energy efficiency, reliability, and safety. The core of a fridge's engineering revolves around the refrigeration cycle, which typically includes a compressor, condenser, expansion valve, and evaporator. The compressor pressurizes the refrigerant, which then transfers heat from the interior to the exterior through the condenser. The refrigerant, now a high-pressure gas, passes through the expansion valve, reducing its pressure and causing it to cool significantly. This cold refrigerant absorbs heat from the interior via the evaporator, where it changes state from liquid to gas. The cycle repeats continuously, maintaining a consistent low temperature. Modern fridge engineering also focuses on integrating advanced insulation materials, energy-efficient compressors, and smart technologies to minimize power consumption and extend the lifespan of the appliance.
