Three-chamber refrigerators

— refrigerators from this category necessarily have a traditional refrigerator and freezer; but the function of the third chamber may be different, depending on the model. The most widely used models are those with a separate fresh zone (see "Features"), the so-called "zero chamber"; however, there are other, more rare and specific options — for example, a built-in wine cabinet (see ibid.).

Note that the presence of a full-fledged third chamber requires a significant increase in size. Therefore, most three-chamber refrigerators are made in the French Door or Side-by-Side format (see "Product type"); there are fewer classic models in this category, and they differ either in increased dimensions or in reduced capacity of traditional chambers (refrigerator and freezer). It is also worth noting that with 3 chambers, the refrigerator can have only 2 doors; see "Number of chambers" for details.
