Abstract:
To provide an air cleaning device which lowers the concentration of toxic volatile substance contained in indoor TVOC, or a heat exchange type ventilation device.SOLUTION: An air cleaning device 1 includes a body 1a, an air supply air passage A, an exhaust air passage B, an air supply fan 6, a circulation opening 15, a circulation damper 10 provided at the circulation opening 15, a circulation air passage C, a removal filter 8 for removing a toxic volatile substance passing an indoor air supply port 3, and a TVOC sensor 9 for detecting the concentration of TVOC passing through an indoor suction port 4. When the concentration of the TVOC detected by the TVOC sensor 9 is determined as TVOC, and first predetermined concentration is determined as V, a control unit 14 forms the circulation air passage C by bringing the circulation damper 10 into an open state in the case of "TVOC>V", and does not form the circulation air passage C by bringing the circulation damper 10 into a closed state in the case of "TVOC≤V".SELECTED DRAWING: Figure 2
