Air conditioning device with indirect cooling by evaporation

An indirect evaporative cooling air-conditioning device, the device being configured to blow cooled air into a room, the device comprising:

• an air intake, configured to collect air that is to be cooled;
• plates, forming a stack, each plate having a dry face opposite to a wet face, the wet face of each plate being configured to be wetted with water, each plate being configured to be cooled under the effect of evaporation of water from the wet face;
• a ventilation system;
• wherein:
• two adjacent plates are spaced away from one another, along a transverse axis so as to form a channel, the channel being:
• either a dry channel, delimited by two dry faces of two adjacent plates,
• or a wet channel, delimited by two wet faces of two adjacent plates;
• the plates are arranged so as to form an alternation of dry channels and wet channels, each dry channel being adjacent to a wet channel, two adjacent channels, respectively one dry and one wet, being connected by a fluid junction;
• each dry channel extends, along a longitudinal axis, between an air inlet, connected to the air intake, and a cold outlet, the cold outlet being configured to discharge air that has been cooled after having flowed along the dry channel;
• each fluid junction connecting a dry channel and a wet channel is positioned at the cold outlet of the dry channel or between the air inlet and the cold outlet of the dry channel;
• each wet channel extends along the longitudinal axis, between the fluid junction and a wet outlet, the wet outlet being configured to discharge air that has been humidified after having flowed along the wet channel;
• wherein:
• each wet channel comprises several wet outlets, distributed along a lateral axis, perpendicular to the longitudinal axis and to the transverse axis;
• and/or each dry channel comprises several air inlets, distributed along a lateral axis, perpendicular to the longitudinal axis and to the transverse axis.
