Refrigeration systems are technologies designed to remove heat from a designated area, thereby lowering its temperature. They work by circulating a refrigerant, a fluid that absorbs heat as it evaporates and releases it when it condenses. Common applications include household refrigerators, commercial freezers, and air conditioning units, all of which help preserve food and maintain comfortable indoor environments. These systems typically consist of four main components: a compressor, condenser, expansion valve, and evaporator. The compressor compresses the refrigerant gas, raising its pressure and temperature. The condenser then cools the gas, turning it into a liquid. The expansion valve reduces the pressure of the liquid refrigerant, allowing it to evaporate in the evaporator, absorbing heat from the
