Upright freezer is an electrical equipment used to refrigerate beverages, food, yogurt, cakes, lunch boxes and other foods. The temperature adjustment range is generally 0~10℃. The types of vertical freezers include cake cabinets, kitchen cabinets, air curtain cabinets, etc., which are mainly used to preserve the freshness of products. The supermarket vertical freezers display products for customers to buy. And different vertical freezers also have different characteristics for different commodities.
1 Introduction to the vertical freezer
The vertical freezer mainly stores refrigerated beverages, as well as some foods that can be eaten at any time, such as some yogurt. Fast food can be placed in the vertical freezer, and the vertical freezer will also have a display screen to clearly express the temperature of the freezer.
Vertical freezers are generally mainly used for commercial purposes, such as some convenience stores, and some supermarkets, etc., will use vertical freezers. In supermarkets, we can often see yogurt and milk in the commodity area. There are some cabinets, this is a type of vertical freezer, and there is a display cabinet that looks like a refrigerator in the place where iced drinks are sold. This is also a type of vertical freezer. For commercial use, the quality requirements are very high, and it can truly achieve low noise, high energy efficiency, and energy saving and environmental protection.
Now some upright freezers are still computer-controlled technology. The temperature is controlled by a computer. It is very simple to operate, and the temperature and quality of the refrigerator are guaranteed. In order to make the placement of the products look more beautiful, the vertical freezer adopts a partitioned storage rack, and the products are placed in different categories, which can make the products look clear at a glance, more practical, simple and generous.
2 Vertical freezer size
Vertical freezers are relatively common in life, and vertical freezers are generally commercial, such as the vertical freezers we see in shopping malls that hold beverages and many more. The size of the vertical freezer varies according to the brand, but the size of the vertical freezer is generally: 2050mm × 700mm × 2200mm, 2700mm × 700mm × 2200mm, the size of the vertical freezer is around this range, and there is not much difference.
3 Upright freezer purchases
The first measure: keep it fresh
Although the freezer is no longer a simple “food refrigerator” “, but the core function of the freezer is to preserve freshness. According to scientific analysis, in order to keep food fresh, on the one hand, the inside of the freezer needs to have a constant temperature and strong “freezing force”, and on the other hand, it is necessary to keep the air in the freezer clean and fresh. Because the purpose of food storage can only be effectively achieved with a strong “freezing force”, the freezing force of the freezer must be raised to a high level in the purchase of the freezer.
Second measure: look at energy consumption
The upright freezer is a complete “electric tiger”, and its electricity consumption occupies the entire electricity consumption of the family. Therefore, choosing an energy-saving freezer that consumes less power is a wise move for you to save money in the future.
The third measure: choose the volume
Don’t underestimate the volume of the freezer, there are thousands of large and small types on the market, don’t hear it Others say that buying a big one is a “rash” decision. The refrigerator is bought for your own use, not for others to see, so it is best to choose the one that suits you. For a family of three, 190-220 liters is enough. Although the large-capacity freezer will give you face from a temporary visual perspective, it may bring you a lot of worries due to its huge space and power consumption “appetite”.
4 Vertical freezer placement
1. It should be placed in a place far away from heat sources and not exposed to direct sunlight. Because it needs to exchange heat with the outside world during work, it is not only through the condenser to the outside world Heat dissipation, the higher the external ambient temperature, the slower the heat dissipation, which will make the commercial freezer and refrigerator work longer, increase the power consumption, and have a poor cooling effect.
2. It should be placed in a place with low humidity. Since the shell of the refrigerator, the condenser and the compressor are all metal materials, if the air humidity is too high, these parts will rust and shorten the life of the refrigerator. service life. At the same time, the humid and overheated environment will cause condensation on the surface of the freezer and affect the performance of the electrical appliance.
3. It should be placed in a well-ventilated place. If there are sundries around the freezer, or it is too close to the wall, it is not conducive to heat dissipation and will affect the cooling effect. There should be a space of at least 30cm on the top of the refrigerator, and a space of at least 10cm on the back and sides to facilitate heat dissipation.
4. It should be placed on a flat and solid ground, and the compressor should be kept level. This is not only required for safety, but also allows the compressor to work smoothly, reducing vibration and noise.
5. It should not be placed in a place where the temperature is too low. Because the temperature is too low, the compressor is difficult to start, which makes the refrigeration of the freezer compartment of the refrigerator poor and cannot be overcome. The refrigerator can turn on the temperature compensation switch of the refrigerator compartment.
6. It should not be placed in the environment of flammable, explosive and corrosive substances. At the same time, do not place such items inside.
7. Do not place heavy objects on the top of the refrigerator to prevent the objects from falling due to the switch and injuring family members.
5 The vertical freezer is better or the horizontal one is better
The vertical freezer and the horizontal freezer are not only different in form and structure, but also different in function types. In addition to direct cooling with air, the cooling method can also use water as a refrigerant for indirect cooling. The storage of food in the horizontal freezer is easy to accumulate, which is not as convenient as the storage of the vertical freezer. However, the upper-opening method of the horizontal freezer makes the loss of cooling capacity less, the structure is simpler than that of the vertical freezer, and the price is cheaper.
The advantages of the upright freezer can be felt from its appearance. The main point is to save space and not take up space. It can also meet various temperature requirements of food.
A major feature of the horizontal freezer is that the product has a good flat display effect, and the products in the cabinet are at a glance, which makes it popular in major shopping malls and supermarkets.
6 Upright freezer temperature regulation
Importance of freezer temperature regulation
The year’s weather changes are divided into spring In summer, autumn and winter, the temperature also changes with the weather. The influence of the outside temperature will naturally affect the temperature inside the refrigerator. When the temperature difference between winter and summer is large, it is necessary to adjust the temperature of the electric refrigerator at home. time, so as to save electricity and ensure the quality of food freezing.
How to adjust the temperature of the refrigerator to save electricity
The temperature control option buttons of the refrigerator are basically 0, 1, 2, 3, 4 , 5, 6, 7 gears, the larger the number, the lower the temperature of the refrigerator compartment. In general, in spring and autumn, we only need to adjust the temperature of the refrigerator to 3 degrees, and the refrigerator will be refrigerated in summer. The cabinet temperature is adjusted to 1st gear or 2nd gear, so as to achieve better energy saving effect.
How to choose the temperature of the refrigerator reasonably
In summer, put more cold drinks, melons and fruits that consume faster in the refrigerator, and the temperature only needs to be kept at 6 -8°C is enough. Adjusting the freezer at -12°C can still keep food fresh for more than a month, and save 25% of electricity. In general, the temperature of the refrigerator should not be higher than 8°C, and the freezer should not be higher than -6°C. Using the above measures will greatly reduce power consumption.
7 What to do if an upright freezer doesn’t cool
The reasons why an upright freezer doesn’t cool
There are various reasons why an upright freezer doesn’t cool , I will introduce 6 common problems:
1. The capillary of the freezer is blocked, so that the refrigerant cannot enter the evaporator, so it cannot absorb the heat emitted by the refrigerator, and the temperature in the freezer cannot be
2. It may be because the screws that fix the buffer pipe of the high pressure output in the compressor are no longer firm, or because the buffer pipe is broken, so the low pressure pipe cannot inhale and the high pressure pipe cannot exhaust , although the compressor is running, but the freezer is not cooling;
3. There is a problem with the refrigeration system, such as leakage, and the freezer that lacks refrigerant heat absorption will naturally not be cooled;
4. The liquid outlet valve and expansion valve of the freezer are not adjusted properly, and the components of the valve plate are not well sealed, resulting in leakage of cold air or wear of the compressor piston;
5. The leakage of the refrigeration system may be caused by Because the freezer is not welded properly or there is a problem with the use method, the cooling speed is slow;
6. It may be that the cooling gear of the refrigerator is too low, which affects the temperature of the freezer.
What to do if the upright freezer is not cooling
In view of the above problems, there are several ways to solve the problem of the upright freezer not cooling:
1. If the capillary is blocked, the capillary must be removed for cleaning;
2. If there is a problem with the buffer tube, you can only open the case, fix the screw or replace a buffer
3. If there is a problem with the refrigeration system, first find the location of the leak in the refrigeration system, weld and repair the location, test the pressure, and evacuate the location. When all the standards are qualified, add a certain amount of refrigeration. 4. If there is a problem with the expansion valve and the liquid outlet valve , first power off the freezer, then turn the inlet valve counterclockwise to the end, remove the screw, install the “pair wire”, then install the pressure gauge and connecting pipe, close the gauge valve, and rotate the intake clockwise Turn the valve once to make it three-way, observe whether the internal pressure of the freezer is normal, and adjust the gear according to different seasons and temperatures.
