Abstract: An air conditioning ventilation system includes an air conditioner, a ventilator, and a control unit. The control unit controls operations of the air conditioner and the ventilator. The control unit causes the air conditioner to perform a compensation operation in order to compensate for a change in at least one of indoor temperature and humidity due to a ventilation operation prior to the ventilation operation to be performed by the ventilator.

Abstract: A control system controls an air conditioner that air-conditions an air conditioning target area using a detection value of a biometric sensor worn by a user, the control system includes a processor that performs a first acquisition that acquires first information related to a distance between a reference point of the air conditioning target area and the biometric sensor, a first determination that determines whether to use a detection value of the biometric sensor for controlling the air conditioner based on the first information and a determination criterion, and a second determination that determines the determination criterion.
