Külmutusosa

Külmutusosa refers to the freezer compartment of a refrigerator. This section is designed to maintain temperatures at or below 0 degrees Celsius (32 degrees Fahrenheit) to preserve food for extended periods. The primary function of a külmutusosa is to freeze items, preventing the growth of bacteria and extending shelf life significantly. It is typically a separate compartment within a larger refrigeration unit, though standalone freezers also exist.

Within a külmutusosa, various types of food can be stored, including raw meats, vegetables, fruits, pre-made meals, and ice cream. The low temperatures achieve this preservation by slowing down or halting enzymatic and microbial activity. Proper storage within the freezer compartment often involves using airtight containers or freezer bags to prevent freezer burn, which is dehydration of food due to exposure to cold, dry air. Defrosting of the külmutusosa may be necessary periodically, depending on whether it is a manual defrost or frost-free model, to maintain optimal performance and prevent ice buildup.
