This creation is about an open energy-saving commercial freezer display cabinet, especially an open energy-saving commercial freezer display cabinet that uses an air curtain generating device to isolate the display space.

In general, the freezer display cabinets used in the market all adopt transparent glass doors. In order to prevent dew condensation on the glass doors, a lot of dew-proof electric heating wires must be installed on the borders and doors of the glass doors to maintain the temperature of the whole glass door above the dew point. To avoid condensation and dripping on the door. In addition, according to the survey of merchants, the sales performance of open (without door) freezing display cabinets is better than that with transparent glass door freezing display cabinets, mainly because consumers can save the action of opening the door to take things, and there is no hidden sight of the door. It is better, which will increase consumers' willingness to shop, but the only disadvantage of open freezing display cabinets is that the power consumption is more amazing, the freezing capacity must be increased by at least 80%, and because it is an open design, the outside humid air is easily penetrated. In turn, it causes serious frost jams in the cooler and requires frequent defrosting to maintain the coldness of the store. It needs to be defrosted every two to three hours, which results in a large increase in power consumption and also affects the preservation of food ingredients. Taking the three-foot open freezer as an example, the daily power consumption may reach 51 degrees, of which the power consumption of defrosting accounts for about 20% to 25%.
