Hybrid heating and ventilating represents one of the most effective ways to provide a comfortable indoor working environment. Both systems are connected to the district energy system, supplying heat to the whole area of industrial facilities. This paper shows the combined effect of radiant heat transfer from hung heating panels situated at the ceiling of a hall and the connected forced-air system used for ventilation.

The theoretical and practical principles for the design and operation of hybrid heating and ventilating systems from the viewpoint of comfort and energy are also presented.
