1. Larger effective volume
The technical parameters of high-quality refrigerators are marked in accordance with the requirements of international standards, and are printed and pasted on the products in a durable and clear printing method. All of them are qualified after many random inspections by the national quality and technical supervision agency over the years.
2. The temperature of the freezer is constant and the cooling speed is fast
The working temperature of a high-quality freezer is distinguished by the most suitable temperature for food storage or preservation. The freezer is 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 freezer not only guarantees that the temperature of the freezer meets the requirements according to the standard, but also makes the cooling speed of the high-quality freezer faster by adopting the special-shaped evaporating tube and matching the unit with the appropriate cooling capacity.
3. Commercial high-power compressor
All high-quality refrigerators 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 refrigerators, frequent start-up times, and long running time 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.
4. The freezer material is better
The high-quality freezer adopts imported 304 stainless steel plate with a thickness of 0.5-0.8 mm. All the evaporating tubes are made of high-quality copper coils and processed into a wide surface profile. The surface of the imported 304 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 refrigerator 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 higher cleanliness in the pipe and fewer pipe joints, which can effectively prevent leakage or blockage 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.
5. The heat preservation effect of the freezer is better
In the production process of the freezer, the insulation performance of the insulation layer is not only an important quality index of the freezer, but also an important factor in the economical use of the freezer. 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 refrigerator with good heat preservation effect be produced.
6. The structure is stronger
The structural strength of the freezer cabinet is directly related to the length of service life of the freezer. There is an integral angle steel frame support between the outer shell and the inner tank of the high-quality freezer, and its function is equivalent to that there are steel bars placed 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.
