<p>PROBLEM TO BE SOLVED: To execute air cleaning without increasing humidity in a summer season or hot season and without lowering temp. in winter season or cold season by forming air passage for sending the polluted air past the dehumidifying section or humidifying section of a humidity control device to an air cleaning device. SOLUTION: This air cleaning device has the humidity control device 4 having the dehumidifying section for dehumidifying the polluted air and the humidifying section for humidifying the polluted air. The passage of the polluted air freely variably to the dehumidifying section or humidifying section is made possible. Namely, the humidity control section 2a is used as the dehumidifying section without operating a heating section and the air may be sent into an air cleaning chamber 8 after dehumidification of the air in the summer season or hot season. The heater 12a is operated and the humidity control section 2a is used as the humidifying section to send the polluted air to the air cleaning chamber 8 after humidifying in the winter reason or cold season. Then, the overhumidifying state of the air is prevented in the summer season or hot season and the increase in the heating load for heating the cleaned air is prevented in the winter season or cold season.</p> |
