Question 2: What's the difference between an air-cooled frost-free refrigerator and a frost-free refrigerator? These two can be said to be one name. Generally, air-cooled and frost-free means that the whole refrigerator is air-cooled whether it is frozen or refrigerated. Frost-free refrigerator refers to air cooling for freezing and direct cooling for refrigeration. Which of these two terms refers to is not clearly defined. Please consult clearly before buying. Generally, direct air-cooled refrigerators are used on three doors, and full air-cooled refrigerators are used on split doors.
Question 3: What is an air-cooled refrigerator and what is the difference between it and a direct-cooled refrigerator? Indirect cooling refrigerator is commonly known as air-cooled refrigerator. Its working principle is to use the fan to promote the gas flow in the refrigerator and realize the refrigeration effect through the evaporator! Belonging to a frost-free refrigerator. Its advantages are fast refrigeration speed, uniform distribution of cold energy, no freezing on the inner wall of the freezing chamber and no need for defrosting! But the things in the box need to be stored in plastic bags, otherwise the water loss will be great. Direct-cooled refrigerator is an inner coil, which uses the cooling capacity of refrigerant flowing in the coil to cool down, and there is no fan in the box. Its advantages are simple structure, small air flow and less water loss, but the freezing room is easy to freeze and needs to be deiced regularly, otherwise it will lead to a decrease in refrigeration capacity!
Question 4: What should I choose for the refrigerator? Is there no frost? Refrigerators should choose manufacturers specializing in the production of refrigerators, I think. There are basically no frost-free two-door ones. In fact, frost-free is air-cooled, just like adding an extra fan to blow around inside. The advantage is that defrosting workers are not needed, and the disadvantage is power consumption and noise.
Question 5: Which is better, frost-free refrigerator or frost refrigerator? Frost-free refrigerators are air-cooled and frost-free refrigerators are directly cooled. The air cooling speed is fast, and the food can be completely frozen without thawing. Direct cooling needs defrosting, which is more troublesome. Now air cooling is hunger, but the price is higher than direct cooling.
Question 6: The difference between air-cooled and frost-free refrigerators is divided into direct cooling and air-cooled refrigerators. Direct-cooling refrigerator is directly cooled by evaporator. Haier adopts the patented technology of embossed aluminum plate evaporator, and its refrigeration effect is better than that of barbed wire. The evaporator can't be seen in the all-air-cooled refrigerator. Refrigeration by circulating cold air is unique. Direct-cooled refrigerator is cheap, but the evaporator will frost, and air-cooled refrigerator is frost-free, but it is expensive. Haier's patented uniform cooling refrigerator just solved this problem. Even cooling refrigerator still belongs to direct cooling refrigerator. The evaporator is on the outer wall of the freezing chamber, and it is wrapped around it for 4 days for direct refrigeration, which has a slight frost effect, which is 20% less frosting than that of the ordinary direct-cooling refrigerator and 30% higher preservation effect.
Question 7: What is the difference between direct cooling and air cooling in refrigerators? The air-cooled frost-free refrigerator does not need manual defrosting, which is convenient to use and reliable in air conditioning. The fan blows out the low temperature of the evaporator to cool the freezing and refrigerating chambers. Ordinary air-cooled refrigerators generally have only one evaporator, which is installed on the back wall between the freezing room and the refrigerating room. It frosts automatically once every 24 hours, and the refrigerating speed is fast, but the refrigerating room is relatively dry. When placing food, especially vegetables, it is advisable to wrap it in a food bag. Because it is automatic defrosting, the power consumption is larger than that of direct cooling refrigerator. The evaporator of the direct-cooling refrigerator is installed in the freezing chamber and the refrigerating chamber respectively, and the temperature is cooled by natural conduction of temperature. Due to the high temperature of the refrigerating room, the frost will automatically melt after the compressor is stopped, and it will be discharged from the refrigerator to the water receiving box above the compressor through the drainage hole under the back wall of the refrigerating room, and then evaporated by the temperature of the compressor, so the refrigerating room does not need manual defrosting, and the freezing room needs manual defrosting regularly, which is more troublesome. For such knowledge, I suggest you pay attention to Weibo, the official Sina website of Hisense Refrigerator, and there will always be relevant information.
Question 8: What do you mean by air-cooled refrigerator? The main feature of air cooling is that there is an automatic defrosting fan, so it is not frozen.
In fact, the air-cooled refrigerator will not produce frost, just let the frost basically condense on the evaporator, not on the inner wall of the refrigerator. In the current mainstream products, the evaporator of air-cooled refrigerator is arranged inside the refrigerator and separated from the inner wall of the refrigerator. Therefore, the inner wall of the refrigerator will not frost, so it is called frost-free. After working for a period of time, the refrigeration is suspended, and the refrigerator will start the defrosting heating system to evaporate the frost condensed on the evaporator. The condensed frost will turn into water when heated, and then it will be discharged through a special conduit (or directly evaporated into steam). This work is done automatically in the refrigerator without manual defrosting.
Direct cooling type is also called natural convection of cold air. The refrigerating room has an evaporator, and the size of the evaporator is reasonably matched according to the size and temperature requirements of the room. The cooling method is to use the natural convection of cold air to cool food, and the freezing speed is slower than that of air cooling. The air-cooled type is equipped with a finned evaporator and a set of air duct circulation components. The fan motor circulates the air in the box cooled by the evaporator up and down to achieve the purpose of refrigeration. Because the cold air blows in, it will not cause the stored food to absorb moisture and frost. So the air-cooled type is also called frost-free type. In fact, frost-free only means that there is no frost on the inner wall surface, and the evaporator surface is still frosted, which is only automatic defrosting without manual defrosting.
Question 9: What exactly does an air-cooled frost-free refrigerator mean? Frost-free refrigerator does not rely on evaporator to contact with food to directly transfer heat, but uses fan to make air flow to realize heat exchange between evaporator and food. The moisture in the air condenses on the evaporator (defrosting regularly), so that the food will not frost.
Question 10: Is it air-cooled and frost-free? There are two kinds of refrigerators and freezers. One is air-cooled and the other is direct-cooled. The advantage of air cooling is that it will not frost, and the air-cooled wind is blown out. It depends on whether your storage can be damp, so it needs air cooling. It doesn't matter that air cooling is more expensive than refrigeration.
