Friges

Friges, commonly referred to as refrigerators or fridges, are household appliances that keep food and beverages cold by removing heat from an interior compartment. They maintain temperatures above freezing to slow bacterial growth and extend the shelf life of perishable items.

Most modern fridges use a vapor-compression refrigeration cycle. A compressor raises the pressure of a circulating refrigerant, which releases heat through a condenser. The refrigerant then expands through an expansion device into an evaporator, absorbing heat from the interior and cooling the cabinet. A thermostat and, in many models, fans regulate temperature and air circulation to maintain uniform cooling throughout the compartments.

Domestic units come in various configurations, including top-freezer, bottom-freezer, side-by-side, and French-door designs. Compact or mini-fridges suit dorms or offices, while built-in or integrated models are designed to fit seamlessly with cabinetry. Some fridges include dedicated freezers, ice makers, water dispensers, adjustable shelves, or smart features for remote monitoring and control.

The history of home refrigeration began in the late 19th century with advances in condenser and cooling technology. Widespread use grew after improvements in insulation and manufacturing, with further refinements to reduce energy consumption and environmental impact. Modern refrigerants and tighter tolerances have led to more energy-efficient and compact designs, while many regions regulate refrigerant types to address environmental concerns.

Energy efficiency and maintenance are common considerations for consumers. Energy guides or rating systems help compare models, and features such as frost-free operation, inverter compressors, and multi-air-flow cooling can improve performance. Regular maintenance includes checking door seals, cleaning coils, and ensuring unobstructed ventilation. Proper disposal of old units and responsible refrigerant handling are important for safety and environmental protection.
