Põhikülmutusosale

Põhikülmutusosale, often translated as main refrigerating part or primary cooling compartment, refers to the central and largest section of a refrigerator or freezer designed for general food storage at chilled temperatures. This compartment typically houses the majority of the refrigerator's cooling capacity and is where most perishable items are kept. It is distinct from specialized compartments such as crisper drawers for fruits and vegetables, or dedicated freezer sections.

The põhikülmutusosale maintains a temperature range generally between 1 to 5 degrees Celsius (34 to 41 degrees Fahrenheit) to inhibit bacterial growth and preserve the freshness of food. Its design usually includes adjustable shelves and door bins to optimize space and organization. The temperature within this section is controlled by a thermostat, which regulates the operation of the compressor and evaporator. Efficient functioning of the põhikülmutusosale is crucial for maintaining food safety and reducing spoilage.
