Abstract

Disclosed herein is an air conditioning system. The conditioning system includes an air handling unit (AHU) configured to control outdoor air that is externally supplied, exhaust air that is outdoors discharged, 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 heat source for a heat exchange to the AHU, a controller configured to receive operating state data of the AHU and control an operation of the AHU through communication with the outdoor unit, and an interface unit connected to the controller and configured to output a control menu of the AHU, send data received through the control menu to the controller, and output a monitoring screen for the operating state of the AHU and the outdoor unit.

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 or warm supply air indoors;
at least one outdoor unit configured to provide a heat source for a heat exchange to the AHU;
a first controller including a processor configured to receive operating state data of the AHU, and to control operation of the AHU by communicating with the outdoor unit; and
an interface to couple to the first controller, the interface to include an input unit and a display screen, and the interface configured to:
display, on the display screen, a control menu of the AHU,
send data, received through the control menu, to the first controller, and
display, on the display screen, a monitoring screen relating to the operating state of the AHU and the outdoor unit,
wherein the first controller provides, to the interface, the operating state data of the AHU, and the first controller sets an operation of the AHU in response to data received from the interface,
wherein the interface having the display screen is configured to be mounted on the first controller and is attachable to or detachable from the first controller,
the interface displays, on the monitoring screen, a flow of the exhaust air, the outdoor air, the return air, and the supply air of the AHU, wherein the interface changes, in real time, the operating state of the AHU in response to data received from the first controller, and displays the changed operating state,
wherein the interface displays, on the display screen, a schedule setting menu for the AHU, and the interface provides, to the first controller, schedule data received through the schedule setting menu,
wherein the first controller includes:
a main unit configured to control operation of the AHU;
an input/output unit to couple to devices including a sensor, a valve, and a damper in the AHU, and the input/output unit configured to transfer a control command of the main unit and to input data from at least one device to the main unit;
a communication unit configured to communicate with the outdoor unit; and
a driving unit configured to control rotational operation of a fan in the AHU,
wherein the driving unit includes an inverter and an inverter driver to drive a motor of the fan, and the driving unit is provided or is removed based on a total number of fans in the AHU.

2. The air conditioning system of claim 1 , wherein the main unit is internally coupled to the input/output unit, the communication unit, and the driving unit, and the main unit is configured to send and receive data, determine an operating state of the AHU in response to data received from the AHU or the input/output unit, and control the operation of the AHU in response to the received data.

3. The air conditioning system of claim 1 , wherein the main unit receives, from a plurality of sensors, data regarding at least one of a temperature, humidity, pressure, an operation signal of the fan, an operating state, an emergency signal, a warning signal, and state information of the AHU, and the plurality of sensors are provided at the AHU.

4. The air conditioning system of claim 1 , wherein the input/output unit transfers, to the valve or the damper, a control command of the main unit so that the valve or the damper operates,
the input/output unit inputs data of the valve and the damper to the main unit,
the input/output unit receives data regarding at least one of a temperature, flow velocity, and degree of air pollution from a sensor at the AHU,
the input/output unit sends the data to the main unit,
the input/output unit transfers a control command of the main unit to a humidifier or a heater in the AHU, and
the input/output unit inputs, to the main unit, operation data of the humidifier or the heater.

5. The air conditioning system of claim 1 , wherein the first controller stores the operating state data of the AHU and the outdoor unit, and stores a control history.

6. The air conditioning system of claim 1 , wherein the interface displays the monitoring screen based on a graphic user interface (GUI) to the air conditioning system in accordance with operating state data received from the first controller.

7. The air conditioning system of claim 1 , wherein the interface displays an operation state of each of the outdoor units coupled to the AHU.

8. The air conditioning system of claim 1 , wherein the interface changes to a standby state when data is not received for at least a specific time, and the interface outputs, while in a standby state, brief information regarding the AHU.

9. The air conditioning system of claim 1 , wherein the interface displays, on the monitoring screen, an image or an icon corresponding to each of a plurality of devices in the AHU, and the images or the icons are provided at the monitoring screen, based on specific locations of the plurality of devices.

10. The air conditioning system of claim 1 , wherein the interface is connected to a connection terminal for communication through a communication line to the first controller, and the interface is configured to send and receive data.

11. The air conditioning system of claim 1 , further comprising a second controller configured to control operation of the outdoor unit,
wherein the second controller is coupled to the first controller, and the second controller is configured to send and receive data of the outdoor unit.

12. The air conditioning system of claim 1 , further comprising a building controller to couple to at least one of a light apparatus, a movement device, a security apparatus, and an alarm apparatus, and the building controller is configured to control the light apparatus, the movement device, the security apparatus, and the alarm apparatus,
wherein the first controller to couple to the building controller, and the first controller is configured to control the AHU in response to a warning signal or a fire signal received from the building controller, and
the building controller controls the light apparatus and the movement device in accordance with an operating state of the AHU.

13. An air conditioning system, comprising:
an air handling device configured to control supplied outdoor air, to exhaust air that is discharged, to control the outdoor air or mixed air of return air and the outdoor air, and to supply air indoors, the air handling device to include at least one sensor;
