The reason why the freezer frost-free, one because the air-cooled freezer evaporator hidden inside the freezer, people can not see it frost; two is the frost can be automatically removed, through the fan and air ducts will be cold air to the various locations of the freezer, because the evaporator does not have direct contact with food, can be warmed by the heating system on the evaporator short time, frost immediately after the recovery of refrigeration, the temperature fluctuations in the freezer less. The evaporator of the freezer because not and food direct contact, can be through the heating system on the evaporator short time heating, frost immediately after the recovery of refrigeration, the temperature fluctuations in the freezer less, both convenient and will not affect the quality of food refrigeration.
Frost-free freezer interior clean and fresh, its cold air system in the refrigeration process will take away the excess moisture in the box, so will not produce frost, food freezing will not freeze together. In addition, its continuous circulation of cold air, after the deodorization system of filtration, so that the smell inside the freezer lasting fresh, greatly reducing the phenomenon of food crosstalk between each other. Cold air system refrigeration, like an air conditioning unit installed in the cooler, cold flow without pore, the temperature in the cooler is stable and uniform. And straight cold cabinet by natural convection direct cooling, like in the freezer put a piece of ice, near the evaporator of food will be very cold, and some far from the evaporator, it is easy to form a frozen dead end, so that food spoilage.
Frost-free freezer temperature uniformity, temperature control point of temperature, is the temperature of any point, the temperature inside the freezer is very. And straight cold cabinet due to the existence of freezing dead angle, temperature control point temperature is often a few degrees different from the actual temperature, affecting the quality of food preservation.
