Air conditioning device using indirect evaporative cooling

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

• an air intake for admitting air to be cooled;
• and
• a plurality of plates forming a stack, the plates being spaced apart from each other along a transverse axis, each plate of the plurality of plates comprising a dry face opposite a wet face, the wet face of each plate being configured to be wetted by water, each plate being configured to be cooled by the evaporation of water from the wet face;
• wherein, in the stack:
• two adjacent plates delimit 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 alternate dry channels and wet channels, each dry channel being adjacent to a wet channel;
• each dry channel extends along a longitudinal axis between a dry inlet, connected to the air intake, and a cold outlet, the cold outlet being configured to blow cooled air from the dry channel;
• and
• each wet channel extends along the longitudinal axis between a wet inlet and a wet outlet the wet outlet being configured to evacuate humidified air following flow through the wet channel, the wet inlet being configured to receive part of the air emerging from the dry channel;
• and wherein:
• the stack is held in a cooling module;
• and
• the cooling module is configured to be inserted into a base and removed from the base, the base defining a housing into which the cooling module may be inserted, the base being arranged to receive the air to be cooled, and/or to evacuate the humidified air resulting from the stack and/or to blow the cooled air.
