PURPOSE:To prevent an occupant in the controlled space from developing allergy to pollen by providing a filter for removing pollen as well as a filter in general use for air conditioning and ventilation in the place of an air filter used in the air duct leading from an air intake for drawing in outdoor air. CONSTITUTION:Signals representing the temperature of outdoor air detected by a temperature detector 6 and signals representing the humidity of outdoor air detected by a humidity detector 7 are inputted to an air-conditioning computer 19 and stored therein; from the data in storage those data needed for a correlation formula are extracted and from the extracted data the correlation formula is calculated and controlling data are obtained; according to the controlling data the air-conditioning computer 19 sends switching signals to an air duct-switching damper 9 and an air duct-switching damper 11 and, by thus switching air ducts, a switching is effected in the use of a filter 8 for general use for air conditioning and ventilation and a filter 10 for removing cedar pollen, for example. |
