Abstract
An air-conditioning ventilation system includes a ventilation device configured to ventilate an air-conditioned space while controlling a ventilation rate, an air-conditioning apparatus that includes a heat exchanger configured to exchange heat between refrigerant and air and that is configured to operate while controlling an air-conditioning capacity thereof to bring an indoor temperature in the air-conditioned space to a setting temperature, and a controller. The controller performs normal control that causes the ventilation device to operate to ventilate the air-conditioned space at a ventilation rate corresponding to the air-conditioning capacity of the air-conditioning apparatus, and recovery control that controls the ventilation rate of the ventilation device such that an integrated value of an amount of ventilation for a time duration from activation of the ventilation device under the normal control falls within a standard ventilation range including a standard integrated value of an amount of ventilation obtained by causing the ventilation device to operate to ventilate the air-conditioned space at a standard ventilation rate for a time duration having a same length as the time duration.
