When summer comes, the temperature rises to speed up the deterioration of food. In order to ensure the freshness of the ingredients, the freezer becomes the best choice for family food storage. In the process of cooling the refrigerator, the moisture in the cabinet is often condensed into a frost layer on the surface of the evaporator. Some users say that when the frost in the refrigerator is the most serious, the thickness of the frost is even more than 6 cm, and covers all the inner walls of the entire freezing chamber. Defrosting the refrigerator has also become a problem that has been criticized by users. In addition to the defrosting time and effort, the six major crimes of frosting in the freezer are also potential hazards to users.
Finely frosted 6 sins: costly and laborious also endangers health
Crime one, causing bacterial infection
Many users think that the low temperature of the freezer can kill bacteria, which is actually a misunderstanding. In fact, the low temperature of the freezer can only control the growth rate of microorganisms, thus delaying the spoilage of food. Some of the psychrophilic bacteria are more rapidly bred in low temperature environments, such as Listeria and Yersinia. Once the refrigerator is frosted, the thick frost layer becomes the hiding place of the bacteria, which increases the cross infection of the food. Once infected, these bacteria can easily lead to acute gastroenteritis and other diseases, which seriously damage the health of the body.
Crime 2, affecting the cooling effect
Frost is a poor thermal conductor, the thermal conductivity is 1/350 of aluminum. Covering the evaporator will greatly reduce the heat exchange efficiency. When the thickness of the frost layer in the freezer exceeds 10mm, it will cause heat insulation between the evaporator and the food in the cabinet. The layer causes the refrigeration efficiency of the refrigerator to decrease. If the frost on the wall of the refrigerator and the cabinet are frosted, a blockage will be formed, which will increase the compressor load invisibly, shorten the service life of the compressor, and impair the cooling effect.
Crime 3, increase power consumption
The frost hinders the heat exchange, making the temperature in the cabinet unstable, and the time and power required for the refrigerator to reach the target temperature is greatly increased. The long-term high-load continuous cooling causes a surge in electricity costs. According to the test, after the frosting of the freezer, it takes an additional one-third of the electricity.
Crime 4, puncture cell wall, nutrient loss
After frosting in the freezer, the volume of ice crystals generated inside the meat and other ingredients will become larger, and it is easy to puncture the cell wall to cause loss of food nutrition. Moreover, these lost nutrients will become nutrients for the rapid propagation of bacteria and accelerate bacterial growth.
Crime 5, occupying space for use
The frost in the freezer will not be cleaned for a long time, and the frost layer will continue to thicken and gradually invade the use space of the freezer. There is no place to store the ingredients, and it is very difficult to find it. Over time, the inner wall of the freezer may also be deformed due to the expansion of the frost layer!
Crime 6, adsorption and release of odor
The frost layer structure is relatively fluffy, with a lot of dense small holes, it is easy to adsorb the odor inside the cabinet. The frost layer melts and condenses repeatedly, and there are various unpleasant odors in the freezer, and the taste of the food is greatly reduced.
Haier innovation 0 frosting freezer upgrade user experience
In order to avoid the trouble caused by frosting, choosing a frost-free freezer is an urgent need for users.
In response to users' pain points, Haier's industry first launched 0 frosting freezer, innovative research and development of three-dimensional jet air supply technology, combined with automatic defrosting and intelligent control procedures to solve the problem of cold air flow and moisture efflux, eliminating the possibility of frosting from the root cause. It not only avoids problems such as bacterial growth, nutrient loss, and electricity, but also eliminates the manual defrosting process, which truly saves the effort and effort.
Its key technology is also reflected in the structural design. Haier has set up a double-layer food basket and a lower cold storage partition to ensure the cold air flow and ensure the best food freezing and preservation effect. At the same time, the N-AB cruise antibacterial module has a bacteriostatic rate of 99.99%, which protects food safety and health, and solves the pain points such as food odor and bacterial cross infection caused by frost in the freezer, which is a frosting problem that has long plagued users. The best solution to lead the user to upgrade the high-end quality life again.
