An air-conditioning ventilation system comprising: a ventilation device configured to ventilate an air-conditioning target space while controlling a ventilation rate; an air-conditioning apparatus including a heat exchanger configured to exchange heat between refrigerant and air, the air-conditioning apparatus being configured to operate while controlling an air-conditioning capacity thereof to bring an indoor temperature in the air-conditioning target space to a preset temperature; and a controller configured to perform normal control that causes the ventilation device to operate to ventilate the air-conditioning target 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-conditioning target space at a standard ventilation rate for a time duration having a same length as the time duration, characterized in that the controller causes the ventilation device to operate to increase the ventilation rate when the air-conditioning capacity of the air-conditioning apparatus is within a preset range and the humidity of the air-conditioning target space exceeds the preset humidity, under the normal control during a cooling operation. a ventilation device configured to ventilate an air-conditioning target space while controlling a ventilation rate; an air-conditioning apparatus including a heat exchanger configured to exchange heat between refrigerant and air, the air-conditioning apparatus being configured to operate while controlling an air-conditioning capacity thereof to bring an indoor temperature in the air-conditioning target space to a preset temperature; and a controller configured to perform normal control that causes the ventilation device to operate to ventilate the air-conditioning target 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-conditioning target space at a standard ventilation rate for a time duration having a same length as the time duration, normal control that causes the ventilation device to operate to ventilate the air-conditioning target 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-conditioning target space at a standard ventilation rate for a time duration having a same length as the time duration, characterized in that the controller causes the ventilation device to operate to increase the ventilation rate when the air-conditioning capacity of the air-conditioning apparatus is within a preset range and the humidity of the air-conditioning target space exceeds the preset humidity, under the normal control during a cooling operation.
