Only as much air as necessary

The health and well-being of its guests are the goals of the Johannesbad Group, which was founded in 1960. At nine locations in Germany and Austria, the family-owned company operates modern clinics, health centres, hotels and technical schools with more than 2,000 employees. The Group stands for the sustainable use of resources and now also wants to take advantage of the economic advantages of optimising the energy of its numerous properties.

If you like to bake, fry and deep-fry, you will appreciate good ventilation. This is all the more true for commercial kitchens with their high air volume turnover. At the Johannesbad Specialist Clinic in Bad Füssing, the ventilation ran all day, although it is not actually needed all the time. Continuous operation generates enormous costs for electricity, heating and cooling. A new, demand-oriented ventilation control system is intended to increase energy efficiency – without compromising on air exchange.

The new kitchen ventilation system is controlled with Siemens Kitchen Air Flow. The innovative ventilation control adapts the air volume flow to the current conditions in the kitchen. The more operation, the stronger the system runs – efficiently and in line with demand. The principle is simple: cooking produces different particles, for example from fat. A powerful sensor measures the concentration of these particles in the air and transmits the measurement result to the control system as a continuous signal. It regulates the ventilation capacity in the same way as the actual kitchen operation.

Kitchen Air Flow makes the kitchen ventilation system at the Johannesbad Specialist Clinic in Bad Füssing significantly more energy-efficient and economical – without compromising on performance. To achieve this, Kichen Air Flow combines innovative measurement technology with modern control technology and reduces energy consumption by more than 60 percent. This means that the system pays for itself after just one year.
