JPH09145093A - Non-water supply dehumidifying/humidifying apparatus - Google Patents

Abstract

PROBLEM TO BE SOLVED: To keep a comfortable room environment in a non-water supply dehumidifying/humidifying apparatus in which it humidifies the inside of a room with water separated from fresh air in the winter season and removes humidity of wet air in the room in the summer season by exhausting odor stored in an adsorbent during the operation interruption of the apparatus. SOLUTION: Odor contained in air during operation interruption of a non- water supply dehumidifying/humidifying apparatus is adsorbed by adsorption means 5. Thereafter, when the operation is restarted, and power supply is detected by detection means, an air passage changeover signal is outputted from timer means, whereby first air passage changeover means 3 is driven to a position of indoor or outdoor air intake and second air passage changeover means 7 is driven to a position of outdoor exhaustion. Simultaneously, a heating signal is outputted to supply power to heating means 4, and air fan means 6 is driven to suck indoor or outdoor air which is in turn heated with the heating means 4. The adsorbed odor is released by regenerating adsorption means 5, and is exhausted from an outdoor exhaust port 9 to the outside for a predetermined time.
