What is a straight cold refrigerator?
The direct cold air mixing refrigeration room adopts direct cooling, the freezing room adopts air cooling, the most comprehensive technology, the effect is also the best, but the structure is too complex, high cost, production of manufacturers is not too much. The so-called mini refrigerator usually refers to the insulation box about 20 liters, because of the semiconductor refrigeration device, thus can refrigeration heating, refrigeration temperature range but belongs to the refrigeration range, reach below freezing temperature, for more medical car refrigerator, refrigerator.
The direct air-cooled evaporator exposure box, through a fan will blow to cold box, cold box has the advantages of uniform, high cooling efficiency, the principle of similar boiling water would be cool fast blow with the mouth, the disadvantage is easy to wind dry food, complex structure and high cost, usually used for high grade products, and a large refrigerator 400 liters or more
The main types of refrigerators are direct cooling type, air-cooled type, wind direct cooling mixed type. The direct cooling structure is that the evaporator is directly exposed to the box body. The advantage is that the cost is low and the fresh water is not lost. It is usually used in two door economical products, and the three door refrigerator is also straight cooling. The control system adopts a computer.
