Rongsheng refrigerator is not refrigerated What is the difference between air cooling and direct coo

For older users, it is common to experience refrigerator defrosting. So how exactly do these creams come from? Rongsheng refrigerator Guangzhou service point to tell you about it:

The reason is actually very simple, most of the water vapor comes from the air, when people store food and open the refrigerator, the indoor air and the gas in the refrigerator will exchange freely, and the humid air in the room will quietly enter the refrigerator. There is also a part of the moisture from the food stored in the refrigerator, such as cleaned vegetables and fruits in the crisper box, the water in the vegetables and other foods evaporates, and condenses into frost after being cold. Especially in summer, the indoor temperature is high, the humidity is high, and the temperature difference between the room temperature and the refrigerator is large.

When the refrigerator is opened, a cool air flows from the inside out, and the indoor air burrows into the refrigerator. It only takes a little time for a layer of hoarfrost to appear on the front wall of the refrigerator. It has also been found that even if nothing is in the refrigerator, a thick layer of frost will form in the refrigerator that is often opened, which shows that a large part of the moisture in the refrigerator comes from the moisture in the air.

Rongsheng refrigerator Guangzhou after-sales service station tells you that refrigerator defrosting has a high trick. Some refrigerators need to be defrosted, and manual refrigerator defrosting is time-consuming and labor-intensive, and the defrosting effect is not good. Hisense Kelong Rongsheng official website here recommends a defrosting trick to you.

According to the size of the inside of the refrigerator, cut a slightly thicker plastic film and stick it on the frosty wall of the refrigerator, without using any glue. When defrosting, temporarily take out the food in the refrigerator, then remove the plastic film and shake it, the frost can all fall off, and then re-apply a film, put in the food, and continue to use. Rongsheng refrigerator Guangzhou special maintenance station to talk about the difference between air cooling and direct cooling:

If you don't want to be with "frost" for a long time, you can also choose an "air-cooled" refrigerator, so what is the difference between it and a traditional "direct cooling" refrigerator? What are their previous advantages and disadvantages? Rongsheng Service Center will give you a detailed analysis next.

Direct cooling] Guangzhou Rongsheng refrigerator special maintenance station Refrigeration principle: direct cooling refrigerator, also known as frost refrigerator, is the use of natural air convection cooling method, by the evaporator through heat transfer to absorb the heat in the food or indoor air to cool and cool. Advantages:

Relatively low power consumption, low noise, slow loss of food moisture Disadvantages: slow refrigeration speed, uneven temperature in the box, easy frosting on the back wall of the refrigerated liner and the evaporator in the freezer, and troublesome defrosting [Air cooling] Guangzhou Rongsheng refrigerator after-sales maintenance point Refrigeration principle: All greenhouses of the refrigerator adopt forced air convection cooling method, and the evaporator is placed in a special refrigeration area in the structure, and the temperature in the box is reduced by relying on the fan to blow the cold air to circulate in the refrigerator.

Advantages: The refrigeration speed is fast and uniform, and the food freezes quickly and keeps it fresh. No frosting, the inside of the refrigerator is clean, and there is no food sticking.

Disadvantages: high power consumption, high noise, fast loss of food moisture.

Hello! Rongsheng refrigerator is happy to answer for you!

Classified according to the type of refrigeration.

Direct cooling (frosted refrigerator, micro-frost refrigerator), air-cooled (frost-free refrigerator) and air direct cooling combined refrigeration.

Categorized according to the mode of control.

Mechanical temperature control: mechanical adjustment of the refrigerator temperature is the simplest way, which can ensure that the food does not deteriorate and meet the needs of food preservation, but the operation is more troublesome, and the artificial temperature adjustment should be carried out according to the change of climate, and the temperature control is not accurate enough, and the real-time temperature in the refrigerator cannot be grasped in time;

Computer temperature control: the whole system is controlled by the computer, the temperature is stable and accurate, the refrigerator with solenoid valve has a double circulation loop, the double temperature controls the temperature of the freezer and refrigeration room, and the refrigeration room can also be closed separately, the control system has a strong comprehensive function, all input parameters and output control are mixed together by the computer, with artificial intelligence, and the computer board displays the temperature as the actual temperature in the box, rather than adjusting the temperature;
