METHOD FOR SELECTING ADDITIONAL VENTILATOR, METHOD FOR SELECTING ADDITIONAL VENTILATOR AND AIR CONDITIONER, AND AIR-CONDITIONING VENTILATION SYSTEM

摘要

The method for selecting a second ventilator (20) according to the present invention is used when newly installing, in an indoor space (SI) where an existing first ventilator (10) is installed, another ventilator as the second ventilator (20). The ventilation volume of the existing first ventilator (10) per hour is defined as a first ventilation volume. In a first step, a second ventilation volume is obtained on the basis of the size of the indoor space. The second ventilation volume is the ventilation volume per hour required for a countermeasure against pathogen infection. In a second step, the difference between the second ventilation volume and the first ventilation volume is obtained as an additional ventilation volume. In a third step, a ventilator capable of carrying out ventilation at the additional ventilation volume is selected as the second ventilator (20).
