Commercial freezers are usually placed in supermarkets and convenience stores, so they are not easily affected by noise. For refrigerators of the same specification, the noise of the air-cooled type is 2-3 decibels higher than that of the direct-cooled type. In fact, this difference is almost negligible, but if there are certain requirements for sound and noise-sensitive merchants, it needs to be carefully considered.

    The fan motor inside the air-cooled freezer is forced to convection, the air is evenly discharged, and the temperature control is more precise. The evaporator adopts a blow-up plate design, which is isolated from the ingredients stored inside, so that the ingredients will not freeze together or stick to the inner wall, and the appearance and freshness of the ingredients will be maintained to the greatest extent.

    The cold air inside the DC chest freezer is naturally conventional, the temperature uniformity is slightly poor, and it is easy to have a cooling dead angle. After all, the evaporator is attached to the box, so the temperature tested by the temperature control point may be different from the actual temperature inside the refrigerator as a whole, which will affect the preservation quality of commodities and ingredients.

    The air-cooled freezer freezes the ingredients quickly by creating cold air. Compared with the direct-cooled freezer, the fresh cold air circulating in the air-cooled freezer makes the cooling speed faster, but the food is easy to air dry. The direct cooling freezer has a good moisturizing effect, and the ingredients will not dry out.
