INSTALLATION DE CLIMATISATION ECONOMIQUE D'UNE ENCEINTE OU D'UN LOCAL

摘要

The building has a surrounding air cavity (6) formed between an internal insulated panel (5) and the outer walls (3). An air circuit in the loft provides incoming fresh air (7) to a distributor (9) consisting of ducts (11) discharging into the cavity and passing into the room through outlets (10). Vitiated air is extracted by the fan (8) and discharged to atmosphere. A heat exchanger (16) is used to heat the incoming fresh air from the heat in the vitiated air. Make-up air can also be introduced through ceiling grilles (15). A ground-heat extraction system (18) is also incorporated and interconnected with the fresh air system.
