Why does a fridge freeze food?
A fridge freezes food as a result of its refrigeration cycle, which involves the circulation of a refrigerant that changes state from liquid to gas as it absorbs heat from the interior of the appliance. The process begins when the refrigerant, typically a freon-based substance, passes through an expansion valve, which reduces its pressure and allows it to expand. As it expands, the refrigerant becomes cold, with temperatures often dropping below 32°F (0°C), causing the evaporator coils to absorb heat from the air inside the fridge. When warm air from the fridge interior comes into contact with these cold coils, its moisture condenses and freezes, forming a layer of frost on the coils and, eventually, on the food if it is in direct contact or close proximity. This freezing process is also influenced by the thermostat, which regulates the fridge’s temperature, usually set between 37°F and 40°F (3°C and 4°C), and the air circulation within the appliance, which helps distribute the cold air evenly. If food is not properly packaged or is placed near the evaporator coils, it can become frozen due to the direct exposure to cold temperatures; similarly, if the fridge’s temperature setting is too low or if there is a malfunction in the defrost cycle, food may also freeze. To prevent unwanted freezing, it’s essential to check the fridge’s temperature settings, ensure proper air circulation, and store food in airtight containers.
