After May Day, although the national epidemic continued to improve and the rapid upward trend was curbed, some experts predicted that there would be repeated outbreaks after the epidemic. A while ago, there was a rush to buy and store goods in Beijing. Some supermarket shelves have been sold out, and the online shopping platform is tired of transportation capacity
I also heard from many friends around me in Beijing that their materials may not only be "sufficient", but even some "waste". Sufficient supplies seem to make Beijing feel more calm and at ease in the face of this wave of epidemic. However, hoarding food materials is not uncommon. Many friends in Beijing, including my mother, have begun to hoard household appliances - among which the freezer is the hottest.
The refrigerator, which has always been "stand aloof from the world" and "not warm and not fire", suddenly made its debut as "position C", ushered in the "highlight moment" and became a top-grade product in the household appliance circle. According to the monitoring data of ovicloud, from March 28 to April 24, the sales scale of refrigerators has increased for four consecutive weeks, and the wechat search index has also soared. The online retail volume of refrigerators has increased by 46.6% and 28.3% year-on-year. On April 20, it reached 17.32 million +. Suddenly, like the spring breeze of the night, the freezer became the "new standard" for national goods hoarding.
In the off-season of sales of cold products from March to April every year, the freezer appears "outshining others" in the spring of 2022. Then, how to judge what kind of freezer is suitable for your home and what aspects to choose from. Next, Xiaobian will take you to have an in-depth understanding.
1、 Horizontal or vertical? There's still a difference!
Many people first consider the volume when buying refrigerators. Household refrigerators can be divided into horizontal and vertical refrigerators. Most people are familiar with horizontal refrigerators. Their doors open upward and are suitable for storing large food materials, such as beef and mutton, seafood, etc. especially there are many frozen food materials at home, they can be considered first.
There is also a popular vertical freezer, just like a refrigerator, which can be stored by category, and it is convenient to take food materials. The disadvantage is just the advantage of the horizontal freezer, and the food materials may not be put down if they are too large.
2、 Refrigeration mode and temperature range are also important
I've heard of direct cooling and air cooling in the refrigerator before, and so is the freezer. The main characteristics of direct cooling freezer are fast freezing, low price and no air drying. The disadvantage is that it is easy to frost and needs to be cleaned regularly.
The internal structure of the air-cooled freezer is relatively complex. The cold air in the box is forced convection, and the temperature uniformity is good. There is no need for manual defrosting, but the price is also relatively high.
In addition to refrigeration, temperature regulation is also very important. The freezer in the double temperature zone has two greenhouses, one can be refrigerated and the other can be frozen, which is equivalent to a refrigerator.
Single temperature zone freezer has only one greenhouse, or only one can be selected for refrigeration or freezing. But now many single temperature zone freezers also have the functions of refrigeration and freezing conversion, which can be used as refrigeration or refrigeration.
3、 Visible freezing force and invisible material
For the freezer, the most important thing is the freezing capacity. The 100 liter freezer is about 5kg / 12h. Freezers generally need faster freezing power when storing a large amount of food. At this time, we pay more attention to the freezer with deep cooling and quick freezing ability. Rapid cooling can ensure that the ice crystal is small, not easy to pierce the cells, and can preserve the nutrition and taste of food as much as possible.
On the other hand, many consumers are easy to be ignored! The pipelines in the freezer are indispensable accessories. The compressor in the refrigeration system is the core component, which needs to use high-quality brand compressors. However, insignificant components such as copper pipes are often ignored.
Usually, the freezer will use copper or aluminum tube materials. In terms of thermal conductivity, copper pipe is significantly better than aluminum pipe or galvanized pipe. In terms of corrosion resistance, freezers using copper pipe are not prone to refrigerant leakage without refrigeration and have a longer service life, while aluminum pipe or galvanized pipe may be corroded and leaked after long use. As the cabinet body also has thermal insulation layer, it is difficult to repair in case of corrosion and leakage, resulting in the scrapping of the whole machine.
It should be noted that in order to reduce the cost, the freezers of small manufacturers are shoddy and will choose aluminum pipe or galvanized pipe to replace copper pipe. The service life of this product may be only 1-2 years. If you add the reduction of other refrigeration accessories, the price of freezers of the same specification is very different. Consumers should not be price oriented and suffer big losses for the sake of cheapness.
4、 Save electricity, trouble and worry!
Like the refrigerator, the freezer also needs 24 hours without shutdown, and energy saving is also very important. According to the national standard, the energy efficiency level is divided into five levels. The smaller the number, the more power-saving. Level 1 is certainly the best, but the smaller the energy consumption, the more expensive the price. Considering the price factors, consumers can consider it by themselves. In addition to the energy consumption level, the purchase of freezers also needs to consider the wide climate and do not worry about shutdown and strike in hot weather; Wide voltage should also be considered, which can operate normally under unstable voltage.
The sterilization of freezers has also attracted extensive attention. Some air-cooled freezer products also have the functions of sterilization, bacteriostasis and taste purification. Efficient sterilization technology can ensure the hygiene and health of food materials.
To sum up, the freezer market shows a multi-point flowering situation. The epidemic prevention and control and demonstration effect have stimulated everyone's demand for food hoarding. The trigger factors have led to the growth of freezer sales and the structural changes of refrigerator products. If your family needs a freezer, you might as well refer to the above suggestions, buy a suitable freezer product, store goods appropriately, and ensure the living materials under the epidemic situation.
