Abstract

The Air Treatment Unit (ATU), of Energetically Efficient Dehumidification and Heating, is equipped with two heat exchangers (12, 19) fed by a Chiller and a boiler respectively and a thermic recuperator (13) between them. While crossing the three components, the forced air flow, actuated by ventilators (14, 21), reaches the humidity and filling temperature in the building for the internal conditions. Concerning this disposition, the ATU allows the use of the heat recuperator in heating periods of 100% of fresh air with/without air humidification (20- humidificator), dehumidification and heating of 100% fresh air or of the mixture of fresh air with addicted air, allowing the reduction of energetic consumption in air treatment. In periods of 100% of fresh air and forced ventilation cooling of the space, a 'bypass' is made for the heat recuperator. This unit assures the air quality inside buildings, avoiding, for example, problems of Legionella, chlorine concentrations on Covered Pools and of CO2 in buildings with humidity control.
