Everyone knows the refrigerated counters in the supermarket that release heat into the air-conditioned fruit and vegetable departments, for example. From an energy point of view, this is not efficient and consumes resources unnecessarily. In addition, many refrigerants have come under increasing criticism in recent decades for being harmful to the climate.
At ITZ Plus, there is a model supermarket in which various refrigeration units are examined and compared. The focus here is on the question of how refrigeration units in the supermarket can be operated as energy-efficiently as possible and which natural refrigerants are suitable for this purpose.
