Abstract
An outside air processing device adjusts the temperature and humidity of outside air taken thereinto, and then supplies the adjusted air to a target space. The outside air processing device includes a heating element configured to heat air, a humidifying element configured to humidify air that has passed through the heating element, and a control unit for outside air processing configured to change the temperature of air at an inlet of the humidifying element in accordance with the humidity in the target space.
Claims7
An air-conditioning system, comprising:
- an outside air processing device configured to adjust a temperature and humidity of outside air taken into the outside air processing device and to supply the outside air to a target space;
- and
- an air-conditioning device configured to adjust a temperature of inside air in the target space,
- the outside air processing device comprising:
- a heating element configured to heat the outside air;
- a humidifier configured to humidify the outside air that has passed through the heating element;
- an airflow rate adjusting element configured to adjust a flow rate of processed air, which is a flow rate of the outside air to be supplied to the target space;
- and
- a controller for outside air processing, the controller comprising processing circuitry that changes a target value of a temperature of the outside air to be supplied to the target space, in accordance with a humidity in the target space to change a temperature of the outside air at an inlet of the humidifier, wherein
- the outside air processing device obtains the outside air independently from the air-conditioning device, and
- if the humidity in the target space is lower than a predetermined humidity, and a heating load of the air-conditioning device is equal to or lower than a predetermined load, the processing circuitry of the controller for outside air processing increases the flow rate of the processed air.
