Glass door manufacturers share how to save electricity with the glass door of the refrigerator

What is the trick to buying glass doors for fruit and vegetable display cabinets? Today, there are a wide variety of fruit and vegetable freezers in the market, but they vary in quality. How do consumers attract eyeballs and choose high-quality fruit and vegetable display cabinet glass doors?

First of all, the glass door of the fruit and vegetable display cabinet has a better heat preservation effect. In the production process of the glass door of the fruit and vegetable display cabinet, the thermal insulation function of the insulation layer is not only an important quality index of the glass door of the fruit and vegetable display cabinet, but also an important factor in the economical use of the fruit and vegetable display rack.

refrigerator. In order to obtain good heat insulation performance, it is necessary to select suitable raw materials and control the bulk density and bubble diameter within a very good range. Therefore, only by adjusting the temperature of the material, cooperating with special fixtures and mastering the mature foaming process can we produce vertical refrigerators and vertical freezers with good thermal insulation effect.

Second, the useful amount is greater. The technical parameters and signs of the glass doors of high-quality fruit and vegetable display cabinets are in line with international standards, and have been inspected by the State Bureau of Quality and Technical Supervision for many times.

Third, commercial high-power compressors.

High quality fruit and vegetable display freezers are commercial compressors. In addition to good starting performance, commercial compressors also have complete cooling capacity and specifications from small to large, and can be configured differently according to different requirements of the product. Only commercial compressors can adapt to the harsh operating environment of commercial refrigerators, frequent start-up time, long running time, and guarantee product quality.

Although the price of commercial compressors is higher than that of household compressors, the failure rate is less than two thousandths.

Fourth, the structure is stronger. The structural strength of the fruit and vegetable display freezer is directly related to the service life of the fruit and vegetable display freezer.

High-quality fruit and vegetable display freezers are supported by a one-piece steel angle structure between the shell and liner. Its function is equivalent to putting steel bars into cement prefabricated panels, thus greatly improving the hardness. After all the door frames are welded and formed, the entire door frame is foam-molded at one time, which avoids the defect that the door of the fruit and vegetable display cabinet is easy to fall due to the insecure installation of the door frame.

Fifth, the glass door of the fruit and vegetable display cabinet has stable temperature and fast cooling speed. High-quality fruits and vegetables can display the operating temperature of the refrigerator, and then distinguish the temperature that is very suitable for food storage or preservation. Suitable for plant-based foods, this freezer keeps the juices in the food below freezing and keeps it fresh.

Freezer temperature is -18°C. Food stored at this temperature has a long shelf life of 1 month. A high-quality freezer can not only ensure that the temperature of the freezer meets the standard requirements, but also use special-shaped evaporation tubes and match the appropriate cooling capacity to make the cooling speed of the high-quality fruit display freezer faster.

Sixth, the raw materials of the glass door of the fruit and vegetable display cabinet are better and of higher quality. All evaporator tubes for fruit and vegetable display freezers are made of high-quality copper pan tubes machined to wide profiles. The appearance of the stainless steel plate is smooth and clean, and the overall thickness is uniform.

Appropriate thickness can not only ensure a long service life, but also make the appearance of fruit and vegetable display refrigerators flat and firm. Copper tubes provide better cooling and corrosion resistance than aluminum or composite tubes. High-quality copper coils have the advantages of high cleanliness and fewer pipe joints, which can effectively prevent leakage or blockage of the refrigeration system.

The circular tube is regarded as a rectangle, so the contact between the transpiration tube and the inner box of the cooling system changes from a point contact to a surface contact, which expands the transfer area and accelerates the cooling speed.
