refrigeration system, lighting system and cabinet. The refrigeration system is composed of compressor, condenser, evaporator, expansion valve or capillary copper tube. The material is colored steel sheet and painted sheet. The protective material in the middle of the sheet is made of polyurethane foam. The types of material cabinets are generally divided into two categories. , one type is without doors, called wind curtain cabinets, and the other type is glass display cabinets with doors.
Glass display cabinets also come in two types: split and conjoined. Basically, it can be said that split and conjoined are two grades and two prices. The big cities in the Pearl River Delta and coastal areas are basically split-type. For example, Xishidao, FamilyMart, Bailichen, etc. are all split-type. The capacity and grade of split type are much higher. Of course, The price is also higher. Of course, there are also higher-end ones, but the one-piece ones are generally cheaper. The split type is divided into an upper compressor and a lower compressor. Many people will ask what is the difference? Which one is better? Let’s give you a brief explanation here. Let’s first talk about the difference between the two types of refrigeration. In fact, refrigeration is a heat exchange process. The heat dissipation effect directly affects the refrigeration effect. In terms of heat dissipation effect, the compressor mounted above will be better. But it can only be said that it is relative. If the decoration on the top of the cabinet is along with the beverage cabinet and the cabinet is against the wall, the heat dissipation effect will be worse. Now most of the beverage cabinets will be packaged with the beverage cabinet on top. If it is packaged, it is best to It is best to connect it directly to the ceiling, and then install an exhaust fan on the ceiling. If the beverage cabinet with a lower compressor is placed against the wall, it must be at least 1 mm away from the wall.
