HEAT EXCHANGE AND VENTILATION DEVICE

WIPO Patent Application WO/2023/248296

A1

A heat exchange and ventilation device (100) comprises a cuboid box-shaped casing (1) inside which a supply air passage (10) and an exhaust air passage (11) are formed, a supply air blower (7) which forms a supply air flow in the supply air passage (10), an exhaust air blower (8) which forms an exhaust air flow in the exhaust air passage (11), a heat exchanger (9) for exchanging heat between the supply air flow and the exhaust air flow, a first partitioning plate (52) that has formed therein a supply air opening portion (54) through which the supply air flow passes and an exhaust air opening portion (53) through which the exhaust air flow passes, and that is situated between the supply air blower (7) and the exhaust air blower (8), and the heat exchanger (9), a second partitioning plate (51) situated between the supply air blower (7) and the exhaust air blower (8), and a control unit (23) for controlling operations of the supply air blower (7) and the exhaust air blower (8), wherein at least a portion of the control unit (23) is accommodated in dead space (12, 13), being space between the heat exchanger (9) and the first partitioning plate (52) through which neither the supply air flow nor the exhaust air flow passes.
