The difference between direct cooling and air cooling in refrigerators
. The fan motor will form the upper and lower circulation of the air in the box after the cooling of the evaporator, so as to achieve the purpose of refrigeration. Because the air is blown into the air, it does not cause moisture to be absorbed from the stored food. Therefore, air-cooled type, also known as frost free, in fact, no frost, but there is no frost on the inner wall, evaporator surface still frosting, but no manual defrost, but automatic defrost.
Air cooled with a fan, automatic defrost, not frozen. Direct cooling, no fan, icing, manual defrost
Direct cold refrigerator moisturizing effect is good, cold food will not be too dry, but frozen easy ice frost. The air cooled refrigerator has a fan, an air door and an air duct, which can keep the air in the refrigerating and freezing room, and the moisture content in the refrigerating room is poor, and the food is easy to dehydrate and dry, and the frost and the ice can be much less. If the air-cooled refrigerator does not have a sealed box, the food has a bad odor.
Direct cooling type, also known as air conditioning, natural convection type. There is an evaporator in the refrigerator, and the size of the evaporator is matched reasonably according to the size of the chamber and the temperature requirement. The cooling method is to cool the food by natural convection of the air conditioner. The freezing rate is slower than that of air cooling. The air cooling type is provided with a fin evaporator and an air duct cycle component
