* The dissipated heat values were measured as per DIN 18873-1 “Methods for measuring the energy use of equipment for commercial kitchens — Part 1”. The type and frequency of appliance usage are decisive for the specification of an air conditioning and ventilation system. These values can be higher than the values indicated for dissipated heat. Guide values can be found in the technical literature, e.g. in VDI 2052. Please consult your specialized design engineer for planning an air conditioning and ventilation system.
