Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated display cabinet design, in particular to an anti-fogging refrigerated display cabinet. Background Art

[0002] A refrigerated display cabinet is another name for a refrigerator or freezer. High-quality freezers utilize high-quality copper coils throughout the evaporator tubes, which are processed into wide, custom-shaped profiles. Stainless steel plates have a smooth, even surface and thickness throughout. Choosing the right thickness ensures both a long service life and a sturdy appearance. Copper tubes transfer heat better than aluminum or composite tubes and offer greater corrosion resistance. High-quality copper coils offer high internal cleanliness and fewer joints, effectively preventing leaks or blockages in the refrigeration system. Rectifying the round tubes allows for surface contact between the evaporator tubes and the cooling liner, rather than point contact. This increases the transfer area and speeds up refrigeration. Refrigerated display cabinets are used to display food, medicine, and other items in a refrigerated environment. They are commonly used in shopping malls, supermarkets, convenience stores, and other locations. They can store a variety of products, including cakes, fruits, vegetables, fresh meat, and medicine. To improve functionality, a fog-resistant refrigerated display cabinet is required.
