Cooling products in the open display cabinets of butchers, cheesemongers and supermarkets is vitally important to prevent spoilage and maintain product quality. Unfortunately, a lot of energy is lost as cold air continuously escapes through the openings of the display cabinets. This leads to higher energy bills.
Fortunately, in practice, we see that many shopkeepers empty and switch off their display cabinets in the evening hours to reduce energy consumption. Unfortunately, this is not always possible due to the large stock present. A solution for this is to use insulation boards in the evening hours to prevent cold air from escaping.
A solution to reduce the energy consumption of open display cabinets is to use insulation panels combined with polycarbonate (minimum 6mm) sliding doors. These adjustments can increase the insulation value of the cabinets and significantly reduce energy consumption. Retailers should seriously consider these solutions to lower their energy bills. Furthermore, these open display refrigerators often have lighting. It is important to check the type of lighting present. In many cases, they are fitted with fluorescent tube lighting. Replacing this lighting with an LED variant not only provides better and brighter illumination of the display cabinet but also reduces energy consumption.
In conclusion, the open display cabinets of butchers, cheese mongers and supermarkets are indispensable for these retailers, but energy consumption can be significantly reduced by using insulation panels and polycarbonate. It is important that retailers seriously consider these solutions not only to lower their energy bills but also to help the environment.
