2 3 TECHNOLOGY Optimizing Energy Consumption

The purpose of Schröter’s ARCTICjet® systems is to cool products that have been previously processed via the application of heat. Just in time for Lemitec 2019 in Kulmbach, the company presented its current project to cut the energy consumption of these intensive chilling systems.

he company’s intensive chilling systems Energy sink (coolant) ensure that the cooling process is fast, T uniform, and controlled. They also reduce water consumption and minimize weight loss. Last but not least, they can cool the products down to the Energy source (recirculation motors) packaging temperature.

By adapting the speed of the recirculation fans to the chamber temperature, Schröter can now consi- derably reduce the energy required. This reduction in fan speed reduces the air volume that flows through the air cooler. The output of the cooler TRADE SHOW decreases at a much lower rate than the energy Energy source (losses) consumption of the recirculation fans, however.

_ IFFA Once Again a Key ENERGY FLOWS OF THE ARCTICJET® The recirculation motors and the losses (heat transfered through the system walls, floor, and ceiling) can be regarded as the heat input (energy source). The air coolers transport energy out of the Trade Show for Schröter system (energy sink). For the following considerations, the losses can be ignored since the system housing is fully insulated.
