Direct Cooling And Air Cooling
Henan Moonpaint Refrigeration Equipment Co., Ltd.
1、 What is the difference between air-cooled refrigerator and direct cooling refrigerator - direct cooling refrigerator
The direct cooling refrigerator, also known as "frost refrigerator", adopts the cooling mode of natural convection of air, and the evaporator absorbs the heat in the food or air in the box through heat transfer to cool the refrigerator. The direct cooling refrigerator is more suitable for use in the dry northern and inland areas in winter.
1. Advantages of direct cooling refrigerator
The utility model has the advantages of simple structure, low failure rate, low power consumption, low noise, good food preservation effect and economic benefits.
2. Disadvantages of direct cooling refrigerator
Easy to frost, slow cooling speed, uneven temperature distribution in the box, poor cooling effect, easy to cause food odor in the refrigeration room and food adhesion in the refrigeration room.
2、 The difference between air-cooled refrigerator and refrigeration refrigerator -- air-cooled refrigerator
The advantage of air-cooled refrigerator is frost free. The air-cooled refrigerator will not always be wet inside like the refrigeration refrigerator, and the food will not adhere to each other. Moreover, the air-cooled refrigerator will have continuous circulation of cold air, and then filtered by the deodorization system, the internal smell will remain fresh for a long time, and there will be no pungent "refrigerator smell". In addition, because the air-cooled refrigerator can defrost automatically. At the same time, the cold air is blown into the refrigerator to reduce the temperature of the refrigerator. The air-cooled refrigerator is more suitable for use in humid areas such as the south.
1. Advantages of air-cooled refrigerator
No frost (automatic defrosting), fast refrigeration speed, uniform distribution of cold air, temperature control, and because the humidity in the box is small, the food will not stick or be wet, not easy to taste, and the product capacity is large.
2. Disadvantages of air-cooled refrigerator
(1) In order to realize the circulation of cold air, the workload of the fan is large, and the automatic defrosting will also increase the energy consumption. Therefore, the power consumption is large, and there is no direct cooling type for energy conservation and environmental protection.
(2) Frequent cold air flow and greater customs lead to rapid evaporation of water and easy loss of food water. If the insurance method similar to closed fresh-keeping box is not adopted, fruits and vegetables and other foods are easy to dehydrate and dry.
