The function of the refrigerator is to keep fresh, the function of the freezer is to freeze, and the refrigerated-freezer conversion cabinet can keep fresh and quick freeze. The temperature of Upright Freezer is -16℃——-26℃. It is used for quick-frozen food, cold drinks and long-term meat. It can be stored in Upright Freezer for a long time. The water in Upright Freezer food is easy to condense into frost. It must be defrosted to a certain extent. The temperature of the refrigerator is 2°C -10°C, so that it will not frostbite the food but also has a fresh-keeping effect. You can put some fruits, vegetables, beer and drinks.

Upright Freezer is a low-temperature refrigeration and freezing equipment for deep freezing. Usually called a freezer etc. Upright Freezer has many uses, from the food industry to the medical industry, etc., can be used. According to different use environment and use effect requirements, the cooling space of Upright Freezer is from -45℃ to 0℃, each has its own interval. Vaporization absorbs heat and liquefaction exotherms.

The Upright Freezer uses a compressor to compress gaseous Freon into high temperature and high pressure gaseous Freon, and then sends it to the condenser to dissipate heat and become liquid Freon at room temperature and high pressure, so the condenser blows out hot air. Then it goes to the capillary and enters the evaporator. After the freon reaches the evaporator from the capillary, the space suddenly increases and the pressure decreases. The liquid freon will vaporize and become gaseous low-temperature freon, which absorbs a lot of heat, and the evaporator will change Cold, using refrigeration or air cooling to achieve cooling in the room (box).

1. It should be placed in a place away from heat sources and direct sunlight. Because it needs to exchange heat with the outside during work, it will dissipate heat to the outside through the condenser. The higher the ambient temperature, the slower the heat dissipation, which will cause commercial refrigerators and refrigerators. The longer the working time, the higher the power consumption and the poorer cooling effect.

 2. It should be placed in a place with low humidity. Since the shell of the refrigerator, condenser and compressor are all metal materials, if the air humidity is too high, these parts will rust and shorten the service life of the refrigerator. At the same time, humid and overheated environment will cause condensation on the surface of the freezer and affect the performance of electrical appliances.

 3. It should be placed in a well-ventilated place. If the freezer is full of debris or is too close to the wall, it is not good for 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 for safety, but also makes the compressor 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, it is difficult to start the compressor, and the refrigeration of the freezer compartment of the refrigerator is poor, which cannot be overcome. The refrigerator can turn on the temperature compensation switch of the refrigerator compartment.

 6. It should not be placed in an environment with flammable, explosive and corrosive materials. 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 causing injury to the family. 5 Upright Freezer is better or horizontal type is better Vertical type refrigerator and horizontal type refrigerator 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 be indirect cooling with water as the refrigerant. The storage of food in the horizontal freezer is easy to accumulate, which is not as convenient as the vertical freezer. However, the open door method of the horizontal freezer reduces the loss of cooling capacity. The structure is simpler than the vertical freezer and the price is cheaper.

 We can feel the advantages of Upright Freezer from its appearance. The main point is to save space and not occupy 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. This feature makes it favored by major shopping malls and supermarkets.

1. Upright Freezer's cooling performance

The performance of refrigeration is mainly based on the comprehensive evaluation of the refrigeration effect and cooling speed of the freezer. As long as these two aspects can meet certain standards, it can be regarded as a freezer with better refrigeration performance, just like if we store it in a freezer. When there is a lot of food, you can observe the refrigeration effect of the freezer to see how long the food in the freezer can achieve the effect of low-temperature preservation. The vertical freezer has the advantage that it is helpful for us to store food, and it is better to choose the suitable one. The temperature range preserves our food. Today's refrigerators will use vertical microcomputer temperature control technology and electronic microcomputer-designed temperature controllers. The temperature controller can automatically adjust the overall temperature of the refrigerator to ensure the freshness and safety of the food stored in the refrigerator. .

2. Understand the energy saving of freezer

The power consumption of refrigerators is a problem that many businesses who need refrigerators will consider. They will give priority to some low-energy refrigerators. In fact, I tell everyone that it is not necessarily a low-energy refrigerator that we use is good. I also need to use it according to our own The actual demand. Although some refrigerators have relatively low energy consumption, their power is also relatively small. If we want to store more food when we use it, the power of the refrigerator will not meet the requirements and the cooling requirements , Affect our use, when we choose the freezer, we should not deliberately pursue the lowest power consumption of the freezer, so as not to affect our use.

3. The design of the freezer

At present, when people buy freezers, they actually see the overall appearance of the freezer at first glance to see if the appearance can meet our requirements. Especially commercial freezers are used in supermarkets and convenience stores with a relatively large flow of people. Locally, the aesthetic appearance is very important, but the practicality of the freezer must also be considered, and whether the raw materials used in the freezer can be durable and corrosion-resistant.

Locally, the aesthetic appearance is very important, but the practicality of the freezer must also be considered, and whether the raw materials used in the freezer can be durable and corrosion-resistant.

Electric glass defrosting function:
The electric glass defrosting function is designed to remove the frost layer formed on the glass surface due to low temperature, ensure the clear visibility of the glass, and provide users with good observation conditions. This function is essential for commercial refrigerators that need to clearly observe the internal items.
Working principle:
The defrosting of electric glass is based on the principle of resistance heating. In the interlayer of the glass, fine resistance wires are embedded or coated with conductive coatings. When current passes through these resistance elements, electrical energy is converted into thermal energy, and the glass heats up.
The frost layer melts into water after being heated, and then evaporates or is discharged along the drainage system of the refrigerator. Since the heat is evenly distributed inside the glass, the entire glass surface can be defrosted synchronously without the situation of local residual frost.
For example, in the resistance wire type electric heating glass, the resistance wire is distributed in a specific arrangement. When the current passes, the resistance wire heats up and the heat is quickly transferred to the glass surface.

Application introduction in commercial refrigerators:
Commercial refrigerators are usually used to store and display large quantities of refrigerated or frozen goods. In low temperature environments, the glass door of the freezer is prone to frost, which affects customers' observation and selection of goods.
Commercial freezers equipped with electric glass defrosting function can effectively solve this problem. Merchants do not need to frequently defrost manually, saving time and labor costs.
Customers can also clearly see the goods in the freezer, improving the shopping experience. Moreover, the continuous clear view helps merchants to better display goods and promote sales.
For example, in the frozen food area of ​​the supermarket, the freezer with electric glass defrosting function allows customers to see the packaging and labels of various frozen foods at a glance, which is convenient for purchase.
In the hotel's kitchen freezer, the chef can quickly and accurately find the required ingredients without having to wipe the frost layer laboriously.
In addition, the electric glass defrosting function also improves the energy efficiency of the freezer. Due to the reduction of the frost layer, the refrigeration system of the freezer does not need to consume more energy to overcome the insulation effect of the frost layer, thereby reducing operating costs.
In short, the application of electric glass defrosting function in commercial freezers not only improves the convenience and display effect of the freezer, but also brings the advantages of energy saving and reduced operating costs.
