HOUSEHOLD AIR CONDITIONER Russian patent published in 2015 - IPC F24F13/20 

FIELD: ventilation.

SUBSTANCE: casing (11) has suction openings (21) of the upper surface and (22) of the lower surface. Fan (15) of the inner installation generates an air flow which is sucked from each of the suction openings (21, 22). The chamber heat exchanger (13) has a shape which is the shape of an inverted V with the heat exchanging parts (13a, 13b) of the front side and (13c) the rear side, and a part (50) for resistance to suction blocks the air flow which is sucked from the suction opening (21) of the upper surface. In particular, the fan (15) of the inner installation generates the air flow which is sucked from each of the suction openings (21, 22) and extends into the heat exchanging part (13c) of the rear side. A part (50) for resistance to suction is located in the suction opening (21) of the upper surface, which faces the heat exchanging part (13c) of the rear side. At that the part (50) for resistance to suction is formed by a part of the casing (11).

EFFECT: eliminating an event when the suction opening of the lower surface is not functioning, which occurs depending on various circumstances, due to ambient conditions.
