In a method of conditioning a room by means of supersaturated air the air is cooled before it is supersaturated. The cooling is carried out preferably by means of direct or indirect water cooling, the water used being either spring water or water circulated in a closed circuit and cooled by contact with a stream of air. If the temperature of the cooling water is not low enough to achieve the necessary cooling of the air the air may be dehumidified by an absorption agent before cooling or a combination of these methods may be employed. Thus cooling water in one circuit may be cooled by evaporation in air and partially dehumidified air is cooled by this cooling water. The thus cooled air is used to cool by evaporation cooling water in a second circuit and this latter cooled water is used to cool further partially dehumidified air. The cooled air may be supersaturated by the apparatus described in Specification 750,559 [Group XII].
