Beverage coolers, primarily referring to specialized equipment used for displaying and refrigerating beverages in commercial settings, are mainly divided into two categories: open-style refrigerated display cases and walk-in freezers with glass sliding doors. The typical temperature setting for both types is 4 degrees Celsius (with a tolerance of ±2 degrees). Open-style freezers are used to store beverages and food with short shelf lives, facilitating easy access and accelerating product turnover.
Most air curtain freezers on the market are split-type (similar to air conditioners where the compressor is mounted outdoors) because the compressor in an air curtain freezer is relatively large, meaning it not only occupies more space but also generates more heat and noise. Therefore, split-type designs are preferred. However, convenience stores generally use integrated units because the compressor is smaller and easier to move. Coca-Cola's donations to various shopping malls are also primarily integrated units.
Common sizes for beverage coolers include single-door, double-door, and triple-door models, and businesses can customize them according to their needs. For example, a standard beverage refrigerated display case has a power of approximately 155W, a capacity of approximately 0.2 cubic meters, and a temperature adjustment range of 2-8℃; a three-door beverage refrigerated display case has a power of approximately 520W, a capacity of approximately 1800L, and a temperature adjustment range of 0-10℃; multi-door beverage display cases generally maintain a preservation temperature between 2-10℃.
Smart freezer solutions based on artificial intelligence and IoT technologies are beginning to be applied, which can improve the operation mode of traditional freezers and help refine terminal operations.
