LG EEV kit . Another major advantage of LG systems is the simplicity of on-site programming . The Smart 5 Controller ’ s user-friendly interface is accessible even to those without technical expertise . Pengelly commended the system for its intuitive design , which removes the need for costly and complex custom software solutions .
This technological upgrade aligns seamlessly with Pick n Pay ’ s sustainability objectives . By adopting these advanced LG systems , the retailer enhances energy efficiency while also lowering operational costs and minimising its environmental footprint .
Pengelly , who has been working with Pick n Pay for 35 years , comments on the retailer ’ s commitment to innovation and sustainability . “ Previously , Pick n Pay ’ s fresh air systems were set manually and locked in place based on the maximum possible population density . By implementing CO₂ sensors , we ’ ve introduced a dynamic , responsive system that adjusts fresh air supply based on the actual store occupancy throughout the day .”
A standout feature of LG ’ s technology is its connectivity . The Smart 5 Controller can be monitored and adjusted remotely through a modem , enabling real-time control from virtually anywhere in the world . “ We can make adjustments from our office or even a smartphone , no matter where the store is located . This level of remote control and programmability is a game-changer for maintaining and optimising air conditioning systems efficiently .”
Along with advanced controls , Pengelly has also suggested the installation of other cutting-edge equipment , such as VRF chillers . These chillers , which utilise inverter technology to adjust performance rather than relying on basic on / off cycling , deliver enhanced efficiency and greater reliability . “ VRF chillers are a great example of how modern technology can enhance our systems . They provide precise control and are much more efficient compared to traditional chillers .”
