Observing the right approaches when heating and ventilating the rooms can make a significant contribution to a suitable hygiene concept. The priority today is to achieve the highest possible air exchange rate. The air is routed in the room by means of displacement ventilation. In addition to the supply of as large a quantity of fresh air as possible, a targeted suction of the "used" air is also important. One of the main advantages is that through the use of displacement ventilation, aerosol clouds can be diluted and carried away from the area of the people in the room. During the upcoming heating season, the system is supported by the thermals, as the warm air rises and transports aerosols and pollutants on its way. The polluted air can then be extracted in a targeted manner under the hall ceiling.
