The individual environmental control system according to the present invention can be largely divided into three components, an individual air conditioner, a control method thereof, and an occupancy sensor.

The individual air conditioner is installed inside a wall of a partition structure such as, for example, an office partition, so as to secure a wider work space, thereby eliminating the risk of damage and inconvenience in use.

The individual air conditioner includes: an air supply duct of an floor air conditioner (access floor) that is a pipe for supplying outdoor air to the individual air conditioner; A diffuser connected to the air supply duct of the floor air conditioner to suck supply air; An air mixing chamber provided with an inlet air amount control damper for controlling the temperature of the air by mixing the air sucked from the diffuser with the indoor air; A fan for supplying air sucked from the air mixing chamber to a main duct by a driving force of a fan motor; An up and down control damper for supplying air sucked from the fan to the upper and lower discharge ports through the main duct, and adjusting the supply direction and supply amount; An upper discharge port for supplying air sucked from the vertical adjustment damper to the room through an upper duct; It is configured as a lower discharge port for supplying the heated air sucked from the vertical adjustment damper to the room through the lower duct.

Best Mode for Carrying Out the Invention An embodiment of an individual air conditioner, which is one of the components of the individual environment control device according to the present invention, will be described in detail with reference to the drawings.

3 and 4, the bottom air conditioner 10 supplies cold air or warm air to the air mixing chamber 13 through the diffuser 11. The air mixing chamber 13 has one end connected to the diffuser 11, the other end connected to the main duct 20, and provided with an indoor air inlet 15 for sucking indoor air. It is provided with an inlet air amount control damper 12 for mixing the outdoor supply air and the indoor air to adjust the temperature of the air discharged into the room through the discharge port. The inlet air volume control damper 12 compares the temperature of the air supplied from the diffuser 11 with the temperature of the indoor air sucked from the indoor air inlet 14 of the air mixing chamber 13, and the most through the controller described later. By determining the temperature of the discharged air to the appropriate room, the temperature of the air supplied to the fan is determined.

The fan motor 14 is installed in the lower part of the main duct 20, which is a connecting portion between the air mixing chamber 13 and the main duct 20, and is embedded in the wall of the partition structure, and the air mixing chamber 13 is provided. Supplying the mixed air supplied from the main duct 20, and is responsible for controlling the amount of air to be released to the room through a controller to be described later. As such, since the fan motor 14 is embedded in the wall of the partition structure, the amount of noise discharged to the outside is reduced, so that a separate noise reduction device is not required.

The main duct 20 is branched into the upper duct 23 and the lower duct 21, and the upper and lower control dampers 25 are provided at the branch points of the upper and lower ducts. The vertical adjustment damper 25 is responsible for converting the air supply direction to the upper duct 23 or the lower duct 21 through a controller to be described later. In this way, depending on the temperature of the supply air and the temperature of the indoor air, it can be determined by selecting the outlet of the air to the upper or lower, more efficient heating is possible, no separate auxiliary heating device is required, it is more economical The individual air conditioner can be obtained.

The upper duct 23 and the lower duct 21 are connected to the upper outlet 24 and the lower outlet 22, respectively, and the upper outlet 24 is positioned below the head of the user sitting on the chair. Discharge openings 22 are respectively installed to be located in front of the user's leg portion. The upper discharge port 24 is provided with a plurality of thin plate-shaped grille, and a swing motor for quickly and repeatedly rotating the grille from side to side is installed inside the upper duct, thereby allowing the user to effect the natural wind. You can feel it.

In addition, the upper and lower discharge ports 24 and 22 are enclosed in the wall of the partition structure, so that only the discharge port is exposed to the outside. Therefore, unlike the discharge port in the conventional individual air conditioner that is provided as a separate box-shaped structure on the upper surface of the desk, the restriction according to the size of the cross section is eliminated, so that it is possible to emit a more comfortable amount of air to the user.

Hereinafter, the individual environment control method according to the present invention will be described in detail with reference to the flowchart of FIG.

(1) The main CPU mounted in the controller first checks whether a user button installed on the controller's panel has been input, and if the user button is input, allows the user to set a desired room temperature. Save it.

(2) Check whether the outing mode is entered, and if the outing mode is entered, stop the operation of the fan motor, swing motor and lighting of the individual air conditioner, and if the outing mode is not entered, proceed to the next step as it is. .

(3) It checks whether the absence mode is input, and if the absence mode is input, stops the operation of the fan motor, the swing motor and the lighting of the individual air conditioner, and if the absence mode is not input, proceeds to the next process as it is. do.

(4) It is checked whether the auto mode is selected, and if the auto mode is selected, the user compares the temperature of the supply air flowing into the air mixing chamber with the current room temperature to determine whether the room temperature value is stored in the first step. The opening degree of the intake air volume control damper and the speed of the fan motor are automatically adjusted to be equal to the set temperature value. That is, as the deviation between the set temperature and the current room temperature increases, the opening degree of the inlet air volume control damper decreases, and the speed of the fan motor increases, and the opening degree of the inlet air volume control damper increases as the deviation becomes smaller. The speed of the fan motor is reduced. On the other hand, if the manual mode is selected, the user can directly control the fan motor, whether the swing motor is driven and the driving speed and the inlet air volume control damper opening degree and the illuminance of the lighting device.

In the third process, for example, the occupancy sensor is mounted on the exterior of the controller, and whether the occupancy of the user is detected by the occupancy sensor, and if there is no input to the occupancy sensor for the waiting time set by the user, When the absent mode is automatically input and the absent mode is input, the fan motor, the lighting and the swing motor of the individual environmental control apparatus are stopped.

In addition, the controller is provided with a communication port, so that the user can control the operation of the fan motor, swing motor and lighting of the individual air conditioner through a PC. For example, as an MS Windows application, serial (RS-232C) communication allows the PC to check the controller's current settings or to transfer new settings to the controller.

As described above, the individual environmental control apparatus and its control method according to the present invention, without reducing the working space, to ensure a discharge port of a sufficient size for a comfortable air flow, and separate noise reduction device or auxiliary heating By eliminating the need for a device, economic efficiency is achieved, and the external exposure of the air conditioner is minimized to prevent the risk of damage, to secure a work space, and to utilize a convenient and reasonable space. Comparing the temperature to automatically supply the air of the temperature set by the user, there is an effect that provides an environmental control system of a more advanced concept.
