  • Arrangement for cooling supply air in an air-conditioning installation
    Patent number: 5931017
    Abstract: The invention relates to an arrangement for cooling supply air in an air-conditioning installation, comprising a heat transfer device for transferring heat between supply air and exhaust air by means of heat transfer surfaces; and a humidifying device for humidifying heat transfer surfaces on the exhaust air side. In order that supply air could be cooled more efficiently, the heat transfer surfaces on the side of supply air and exhaust air are separated into separate heat exchangers; and the heat transfer surfaces are selected in such a way that the surface temperature of the heat transfer surfaces on the exhaust air side is close to the dew-point temperature of exhaust air.
