1. The temperature of the fresh-keeping cabinet in the supermarket fresh-keeping cabinet is constant and the cooling speed is fast

The working temperature of the high-quality supermarket fresh-keeping cabinets is distinguished by the most suitable temperature for food storage or preservation. The refrigerators are suitable for plant foods, which can ensure that the juice contained in the food is not lower than the freezing point and keeps its fresh state. The temperature of the freezer is -18 degrees Celsius, and the shelf life of food stored at this temperature is up to 1 month. The high-quality fresh-keeping cabinet not only guarantees that the temperature of the fresh-keeping cabinet meets the requirements according to the standard, but also makes the cooling speed of the high-quality fresh-keeping cabinet faster by using a special-shaped evaporator tube and matching a unit with a suitable cooling capacity.

2. The effective volume of the supermarket fresh-keeping cabinet is larger

The signs of the technical parameters of the high-quality preservation cabinets are in accordance with the requirements of international standards, and all have passed the random inspections of the national quality and technical supervision agency over the years.

3. The heat preservation effect of the supermarket fresh-keeping cabinet is better

In the production process of the fresh-keeping cabinet, the thermal insulation performance of the insulation layer is not only an important quality index of the fresh-keeping cabinet, but also an important factor in the economical use of the fresh-keeping cabinet. In order to achieve good thermal insulation performance, appropriate raw materials must be selected, and the bulk density and cell diameter must be controlled within the optimal range. Therefore, only by adopting the ability to control the material temperature, cooperate with special fixtures, and master the mature foaming process, can the preservation cabinet with good heat preservation effect be produced.

4. The structure of the supermarket fresh-keeping cabinet is stronger

The structural sturdiness of the cabinet body of the supermarket fresh-keeping cabinet is directly related to the length of service life of the fresh-keeping cabinet. There is an integral angle steel frame support between the outer shell and the inner liner of the high-quality supermarket fresh-keeping cabinet of the display freezer. Its function is equivalent to that there are steel bars in the cement prefabricated board, and the firmness is greatly increased. After the door frame is completely welded and formed, the whole is foamed and formed at one time, which avoids the defect that the door frame is not firmly assembled and the cabinet door is easy to fall off. The integral steel frame has obvious advantages in one-time forming. Why don't other manufacturers adopt it? Because the fixture requirements are complex and the installation is difficult, it is impossible for manufacturers to adopt this structure and technology for the interests of consumers everywhere.

5. Commercial high-power compressors for supermarket fresh-keeping cabinets

All high-quality preservation cabinets use commercial compressors. Commercial compressors have good starting performance and complete specifications from small to large refrigeration capacity, and can be configured in different ways according to different requirements of the product. Only commercial compressors can adapt to the harsh operating environment of commercial fresh-keeping cabinets, frequent start-up times, and long-running time characteristics to ensure product quality. Although the price of commercial compressors is higher than that of domestic compressors, the failure rate is less than two thousandths.

6. The material of the supermarket fresh-keeping cabinet is better

All evaporating tubes of high-quality supermarket fresh-keeping cabinets are made of high-quality copper coils and processed into wide-faced special shapes. The surface of the stainless steel plate is smooth and clean, and the thickness of the whole plate is uniform. The use of an appropriate thickness not only ensures a long service life, but also makes the appearance of the fresh-keeping cabinet flat and strong. Copper pipes have better cooling effect and better corrosion resistance than aluminum pipes or composite pipes. High-quality copper coils have the advantages of high cleanliness in the pipe and fewer pipe joints, which can effectively prevent internal leakage or blockage failures in the refrigeration system. The round tube is processed into a rectangle, so that the contact between the evaporation tube and the cold transfer liner is changed from point contact to surface contact, which enlarges the transfer area and speeds up the cooling speed.
