Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An air-conditioning system comprising: an indoor temperature/humidity sensor detecting at least either a temperature or a humidity of air in a target space; a chiller adjusting at least a temperature of outside air taken into the target space; an air-conditioner adjusting at least the temperature of air in the target space, the air-conditioner having a plurality of indoor units; and a controller, and a storage storing a program that causes the controller to: determine a temperature/humidity state that is at least either the temperature or a humidity of the air in the target space; determine a load factor of the air-conditioner, and an operation factor, the operation factor being a ratio of the indoor units operating among the plurality of indoor units; and stop an operation of the air-conditioner: when the determined temperature/humidity state is within a predetermined range; when the determined load factor is below a predetermined lower limit; and when the determined operation factor is greater than or equal to a predetermined operation factor. 2. The air-conditioning system of claim 1 , wherein when the temperature/humidity state is determined to be outside the predetermined range after a predetermined period of time has elapsed since the operation of the air-conditioner is stopped, the program causes the controller to restart the operation of the air-conditioner. 3. The air-conditioning system of claim 1 , wherein the program causes the controller to stop the operation of the air-conditioner, and forcibly increase an air conditioning capacity of the chiller. 4. The air-conditioning system of claim 2 , wherein the program causes the controller to stop the operation of the air-conditioner, and forcibly increase an air conditioning capacity of the chiller.
