In an air-conditioning system including an outside air processing device and an air-conditioning device, an operation of either one of the outside air processing device or the air-conditioning device is stopped if a temperature/humidity state that is at least either the temperature or humidity of air in a target space is within a predetermined range and if the load factor of at least one of the outside air processing device or the air-conditioning device is below a predetermined lower limit.

Air-conditioning system

When an outdoor air handler performs a heating humidifying operation and an air conditioner performs a cooling operation, a control device adjusts at least one of a to-be-supplied air temperature of the outdoor air handler, a to-be-supplied air flow rate of the outdoor air handler, a to-be-supplied water flow rate of the outdoor air handler, and a cooling temperature that is a temperature at an air heat exchanger of the air conditioner. The control device adjusts the to-be-supplied air temperature and the cooling temperature on the basis of dehumidification information, operation information, temperature information, and humidity information. The operation information is information regarding an operating state of the air conditioner.

Air conditioning system

It is an object of the present disclosure to collectively control an outdoor air handler and an air conditioner optimally. An air-conditioning system () includes an outdoor air handler () configured to adjust a temperature and a humidity of taken-in outdoor air and supply the air to a target space (SP, SP), an air conditioner () configured to adjust a temperature of air in the target space (SP, SP), and a control unit (). The control unit () is configured to, in a case where one of the outdoor air handler () and the air conditioner () is in a non-temperature adjusting state in which the temperature of the air is not adjusted, change an air conditioning capacity of the other one of the outdoor air handler () and the air conditioner () compared with a case where the outdoor air handler () and the air conditioner () are in a temperature adjusting state in which the temperature of the air is adjusted.
