Abstract

An air conditioning system includes an air handling unit (AHU) configured to control outdoor air that is externally supplied, exhaust air that is discharged from indoors to outdoors, and return air that is circulated indoors and supplied again, control the outdoor air or mixed air of the return air and the outdoor air at a set temperature, and supply cool/warm supply air indoors, at least one outdoor unit configured to supply a refrigerant to the AHU, a controller configured to control the AHU through communication with the outdoor unit, and an interface unit configured to operate as an input/output unit of the controller. The interface unit displays setting menus for devices forming the AHU, sets basis data for controlling the devices in response to data received through the setting menus, inputs the set basis data to the controller, and outputs a control menu and a monitoring menu in accordance with functions of the AHU changed according to a configuration of the plurality of devices.

First claim

What is claimed is:

1. An air conditioning system, comprising:
an air handling unit (AHU) configured to: control outdoor air that is externally supplied, exhaust air that is discharged from indoors to outdoors, and return air that is circulated indoors and supplied again, control the outdoor air or mixed air of the return air and the outdoor air, and supply cool/warm supply air indoors, the AHU including a plurality of devices;
at least one outdoor unit configured to provide a refrigerant to the AHU;
a controller configured to control the AHU by communicating with the outdoor unit; and
an interface configured to operate as an input/output device, the interface to display a control menu and a monitoring menu based on functions of the AHU changed according to a configuration of the plurality of devices of the AHU, and
wherein the interface classifies functions into functions of the AHU that are executable and functions of the AHU that are not executable, based on the configuration of the plurality of devices,
the interface displays the classified functions, and menu items for the functions that are not executable are deactivated, and
the interface displays setting menus for the plurality of devices of the AHU.

2. The air conditioning system of claim 1 , wherein the interface sets data for controlling the plurality of devices in response to data received through the setting menus, and the interface inputs the set data to the controller.

3. The air conditioning system of claim 2 , wherein when setting for the plurality of devices is performed and the data for the plurality of devices is set, the interface determines whether each of the plurality of devices operates normally.

4. The air conditioning system of claim 2 , wherein the interface differently configures menus according to a user, an administrator, or an installer, based on login rights, and the interface displays the configured menus.

5. The air conditioning system of claim 4 , wherein:
the interface displays an operation menu for controlling operation of the AHU and the monitoring menu for outputting an operating state of the AHU in real time for all login rights.

6. The air conditioning system of claim 4 , wherein the interface differently displays the setting menus for the plurality of devices, as the control menu, based on the login right,
wherein the setting menus include submenus including administrator setting menus for controlling the operation of the AHU and system setting menus for setting a basic value or basic control value of each device at the AHU.

7. The air conditioning system of claim 6 , wherein the interface displays all of the setting menus when the login right corresponds to the installer, and the interface displays the administrator setting menus except the system setting menus when the access right corresponds to the administrator.

8. The air conditioning system of claim 1 , wherein the interface sets a range in which each of the plurality of devices operates as the data regardless of a model and a type for each device and controls the plurality of devices.

9. The air conditioning system of claim 1 , wherein the plurality of devices include a sensor, a valve, a damper, and a fan.

10. The air conditioning system of claim 1 , wherein the interface outputs a warning based on an error or erroneous connection when received data exceeds a settable range with respect to functions of the AHU or the data for controlling the plurality of devices.

11. The air conditioning system of claim 1 , wherein when the plurality of devices is changed, the interface provides a new control menu and a new monitoring menu for the AHU based on the changed plurality of devices by removing information regarding a removed device or adding and setting information regarding a new device.

12. The air conditioning system of claim 1 , wherein the interface is detachably configured at the controller, and the interface is connected to the controller using a wired or wireless communication method.

13. The air conditioning system of claim 1 , wherein the interface sets a schedule pattern for each day-of-the-week, the interface sets an operation schedule of the AHU based on schedule data to which a plurality of the schedule patterns has been applied, and the interface provides the set operation schedule to the controller.

14. The air conditioning system of claim 1 , wherein the interface receives error data of the AHU and stores an error history, the error history including a date of the error, a time of the error, code, and information regarding a device that generated the error.

15. The air conditioning system of claim 1 , wherein the interface receives, from the controller, data of the AHU and the outdoor unit, and the interface displays the monitoring menu and the control menu using graphics.

16. The air conditioning system of claim 1 , wherein the interface displays, on the monitoring menu, a flow of the exhaust air, the outdoor air, the return air, and the supply air of the AHU.

17. The air conditioning system of claim 1 , wherein the interface displays, on the monitoring menu, an image or an icon that corresponds to each of the plurality of devices of the AHU and the outdoor unit based on location of each of the devices.

18. The air conditioning system of claim 17 , wherein the interface changes a shape and a location of the image or the icon of each device in the monitoring menu when a configuration of the plurality of devices changes, and the interface displays, on the monitoring menu, the changed shape and changed location.

19. The air conditioning system of claim 17 , wherein the interface changes at least one of a shape and a color of the image or the icon based on an operation shape of each of the devices in response to data received from the controller, and
the interface displays at least one of the shape and the color, and outputs, in real time, an operating state of the AHU.

20. The air conditioning system of claim 1 , wherein the interface displays a setting menu for a sensor.
