An apparatus for cooling indoor air which comprises a horizontally extending primary air duct (11) having essentially vertical long side walls (15), at least one cooling coil (12) for room air and a mixing chamber (13) for primary and room air and openings (17, 23) for the flowing of circulation air into and from the room. The apparatus is characterized in that cooling coils (12) are provided with space outside and along one or both of the vertical long side walls (15) of the primary air duct (11), thus forming a long narrow room (13) constituting said mixing chamber which is defined upwards by an upper partition wall (14) over a projecting part of the primary air duct (11), towards the one side by the vertical long side wall (15) of the primary air duct (11) and towards the other side by the cooling coil (12) and downwards has a direct connection to respective openings (17, 23), which in turn has connection with the room. Each cooling coil (12) has openings (22, 16) provided for an essentially horizontal input air flow from the room and an output flow to the mixing chamber (13) of air cooled in the cooling coil (12), respectively. Openings (19) for primary air are provided in the upper partition wall (14) between the part of the primary air duct (11) projecting over the mixting chamber (13) and corresponding mixing chamber (13) so as to provide an input primary air flow to the mixing chamber (13) being parallel with the side of the mixing chamber (13) facing to the cooling coil (12) and thus also essentially perpendicular to the chilled room air flow streaming out from the cooling coil (12) and into the mixing chamber (13). |
