HEAT EXCHANGE VENTILATION DEVICE WITH AIR PURIFICATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2022/018983
Kind Code:
A1
Abstract:
An heat exchange ventilation device (50) with an air purification function comprises: a heat exchange ventilation device (10) for exchanging heat between an exhaust air flow (2) circulating through an exhaust air channel (4), which discharges air in an indoor space (11) to an outdoor space (12), and a supply air flow (3) circulating through a supply air channel (5), which supplies air from the outdoor space (12) to the indoors space (11); a humidifier (6d) for adding a component that purifies air together with water to the supply air flow (3) after having exchanged heat, introduced from the supply air channel (5); a heat exchanger (16) for performing, on the upstream side of the humidifier (6d), dehumidification on the supply air flow (3) after having exchanged heat; and a control unit (8) for controlling the heat exchanger (16). When performing humidity adjustment so that the humidity of the supply air flow (3) fed to the indoor space (11) reaches a target setting humidity for the air in the indoor space (11), the control unit (8) controls, on the basis of humidity information relating to an increase in humidity of the supply air flow (3) due to the humidifier (6d), the amount of dehumidification performed on the supply air flow (3) by the heat exchanger (16).
