Cold storage is used to maintain the quality and prolong the use of products. Lighting requirements of cold storage differ from other applications because of the low ambient temperature and moisture environment. Some cold storage features -30 °C freezing temperature. Moreover, cold storage has limited exits and windows to ensure effective cooling performance. Food, pharmaceuticals, and other products are stored on high racks in cold storage. Besides, people seldom walk in unless they need goods in cold storage. According to the above features of cold storage, we can conclude that cold storage lighting must meet the following demands.
- It can work stably under -30 °C with low maintenance and has high ingress protection.
- Cold storage lighting fixtures should emit less heat to avoid increasing the load on the cooling system. In many high-rack environments, lighting patterns should be long and narrow in aisle areas, which can make sure light is fully used without waste. What’s more, forklift drivers must be able to look up and down the stacks and the products, so the horizontal and vertical lighting levels can make human eyes feel comfortable to enhance job safety and work efficiency.
- People seldom walk in cold storage, which requires lighting with multiple intelligent control options, enabling cold storage facilities to dramatically reduce both operating and maintenance costs.
