VENTILATION AND AIR-CONDITIONING APPARATUS AND METHOD FOR CONTROLLING SAME

摘要

To include a supply-air passage that leads from a supply-air intake port (9) to a supply-air blowout port (8), a discharge-air passage that leads from a discharge-air intake port (10) to a discharge-air blowout port (7), a heat exchanger (4) that performs heat exchange between air currents flowing through a supply-air passage and a discharge-air passage, a bypass passage that is provided in parallel to the discharge-air passage and bypasses the heat exchanger (4), a supply-air blower (3) that supplies air to a room, a discharge-air blower (2) that discharges air outside a room, a damper (12) that switches whether to pass discharge air through the heat exchanger (4), a temperature sensor (11) that measures a temperature of air supplied to a room, and a control unit (14) that controls the supply-air blower (3), the discharge-air blower (2), and the damper (12). The control unit (14) controls a throttling degree of the damper (12) based on an output of the temperature sensor (11) so that a temperature of air supplied to a room approaches a predetermined temperature.
