The choice of commercial refigerator is much more complicated than other household appliances to a certain extent, but after all, not everyone wants to be an expert in refrigerator research, everyone just wants to make decisions with the fastest speed. Therefore, many people will think about how to quickly understand the purchase method of refrigerators.
Here, let's take a look at the "ten basic common sense" for refrigerator purchase. Through these common sense content, maybe we can see some ways.
Choose a brand, with strong professionalism and guaranteed product quality, and reliable，after-sales service, such as Carbinjoy, Kalifon, a refrigerator produced by a joint venture of Panasonic. The after-sales services of good brands are very convenient and will not be ignored.
You get what you pay for. If you want to buy it for a long time, you can buy it a little more expensive, because after all, it is something that you need to use frequently. The price of different refrigerators is also different. The low price is one or two thousand, and the high one is tens of thousands. For a family of three, a refrigerator with a medium price is enough
According to personal preferences, everyone chooses different styles of refrigerator doors,glass door refrigerator, single door, double door, three doors, four doors, which are determined according to the room type.
Capacity is everyone most focus on. The refrigerator is used to store things. Of course, the more things that can be put, the better. The best is to choose according to the usable area of the house and personal needs.
The refrigeration methods of refrigerators mainly include: direct cooling, air cooled, and mixed cooling.
According to cost performance: air cooled > mixed cooling > direct cooling
In simple words, the three cooling methods are briefly introduced
Direct cooling
As we all know, the oven generates heat through a heating tube, and the food is matured through heat transfer.
The direct cooling refrigerator is like an oven. The oven is a heating tube. You can understand that the direct cooling refrigerator is a "cooling tube", which transfers the cold air to the food to cool the food. However, there is a very big flaw in the direct cooling refrigerator, that is, the freezer will be frosted. I believe everyone should have seen this when they were young. The thicker the knot, the thicker it is, and it must be defrosted at least twice a year.
Air cooled
If you don't want to have the trouble of defrosting, you can choose the more common air cooled now.
Air-cooled refrigerators have a fan or air outlet inside, which continuously circulates cold air to the food to cool down the food. The air-cooled refrigerator does not have the trouble of defrosting the direct-cooling refrigerator, but the air-cooling will take away the moisture on the surface of the food, just as the air conditioner will dry the skin.
Mixed cold
The mixed-cooling refrigerator is a product that learns from each other's strengths and complements its shortcomings. Generally, the refrigerator compartment is directly cooled, which can maximize the freshness of the food; the freezer compartment is air-cooled, which can avoid the trouble of defrosting.
There is no absolute difference between these three refrigeration methods, but in terms of comprehensive cost-effectiveness, the more common air-cooled refrigerators are preferred, and families with sufficient budgets can choose mixed cooling.
The working methods of refrigerators are mainly divided into frequency conversion and fixed frequency. Between of two method, frequency conversion is better than fixed frequency. For better preservation effect, frequency conversion is preferred. Let's take a look at the traits of both.
Inverter refrigerator, as the name suggests, the compressor frequency of the refrigerator can be changed. When the temperature is high, the compressor of the refrigerator is relatively fast. In this way, the refrigerator can cool better; and when the temperature is lowered, it will run at the lowest speed, so that the refrigerator can maintain the internal temperature well. Frequency conversion effectively extends the life of the refrigerator.Therefore, inverter chillers are more energy efficient than fixed frequency and generate less noise during operation.
The speed of the compressor of the fixed frequency refrigerator is fixed during operation, and its speed is generally between 2950-3000rpm. The compressor will stop when the internal temperature of the refrigerator reaches the set temperature during the operation of the refrigerator. When the temperature rises, the compressor of the refrigerator will start restarting again.
The chiller of the fixed frequency refrigerator mainly relies on the stop and start of the compressor to achieve temperature control. Compared with inverter refrigerators, fixed-frequency refrigerators have poor temperature control accuracy, generate more noise during operation, and consume more power.
When buying a refrigerator, we need to pay attention to the function. In addition to the two conventional functions of preservation and freezing, there are now sterilization, deodorization, and zero-degree preservation. The more functions, the higher the corresponding cost. You may select with your personal wishes.
Check whether the surface of the box is flat and whether there is any depression or deformation. Test whether the door of the refrigerator is opened and closed normally. At the same time, pay attention to the stability and sealing of the refrigerator.
The freezing capacity reflects the cooling speed of the refrigerator, how many kilograms of beef can be reduced from 25 degrees to minus 18 degrees in 12 hours. The greater the freezing capacity, the better the cooling effect and the better the freshness."Fast cooling" is another manifestation of this.
The freezing capacity of the refrigerator is mainly related to two aspects: 1. The space size of the freezer compartment; 2. The refrigeration performance of the refrigerator.
