A refrigerator is an essential household appliance designed to store food and beverages at low temperatures to keep them fresh for longer periods. It works by removing heat from the interior compartment and maintaining a controlled, cool environment, typically ranging from 35°F to 40°F (1.6°C to 4.4°C) for the main compartment and below 0°F (-18°C) for the freezer.
A refrigerator is an essential household appliance designed primarily for the preservation of perishable food and beverages by maintaining a consistently cool internal environment well below room temperature. Its core function relies on the refrigeration cycle, a thermodynamic process typically using a vapor-compression system: a refrigerant fluid circulates through sealed coils, absorbing heat from the interior cabinet as it evaporates into a gas within the evaporator coils (located inside the fridge/freezer), then is pumped by a compressor to the condenser coils (usually on the back or bottom), where it releases the absorbed heat to the surrounding air as it condenses back into a liquid, aided by a condenser fan. This cooled liquid refrigerant then passes through an expansion device (like a capillary tube or valve) to reduce its pressure and temperature before re-entering the evaporator to repeat the cycle.Top of Form
