Refrigerator cooling methods are mainly divided into air-cooled and direct-cooled two types.
Air-cooled freezer is mainly used to force the air convection cooling approach, through the fan of the air supply, so that the entire freezer internal stability to achieve the expected, so as to cool down. And direct-cooled freezer through the evaporator, absorb heat for cooling. Air-cooled freezer due to more fan air, so the freezer indoor temperature is more average, there is no great temperature change, the cooling effect is also naturally more outstanding, while taking into account the role of the fan, air-cooled freezer cooling speed is naturally faster than the direct cooling refrigerator to some. But also taking into account the role of the fan and the complex wiring design, air-cooled freezers in energy consumption and noise compared to the direct-cooled freezers to a lot higher. At the same time we should note is that the fan for food air-drying role is also we can not ignore, so air-cooled freezer food drying to relatively faster. In the defrost performance is excellent air-cooled refrigerator.
