For convenience store owners, chain expansion directors, and store contractors, when planning beverage and fresh food display areas, the choice between "air curtain cabinets (open-display refrigeration) and door-type refrigerated display cases (closed-display refrigeration)" is a key decision that determines the efficiency of store traffic flow and daily operating costs.

Traditional air curtain cabinets (open-top + air curtain): Cool air escapes easily, forcing the compressor to operate continuously at high load; energy consumption at night can be more than 60% higher than that of models with doors. Actual tests show that without a glass door, the cabinet temperature rises rapidly (by approximately 1°C in 1 minute), whereas with a glass door, this rise is delayed to 1°C in 3–4 minutes, resulting in energy savings of about
Add a glass door: The combination of a glass door and an air curtain provides double insulation, significantly reducing cold air loss, shortening compressor runtime, and substantially lowering long-term electricity costs
Energy Consumption and Operating Costs: Due to their open design, air curtain cabinets inevitably allow cold air to escape into the surrounding environment, requiring the refrigeration system to work harder to maintain temperature. Consequently, their energy consumption is significantly higher than that of refrigerated cabinets with doors (for example, a standard air curtain cabinet consumes approximately 8–9 kWh per square meter per 24 hours). In contrast, refrigerated display cases with doors effectively trap cold air behind their glass doors, significantly reducing the load on the compressor and resulting in substantial long-term savings on electricity bills.
