BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an operation control device for a turbo blower, and more particularly, to an operation control device for a turbo blower that satisfies user requirements and minimizes product damage.

Turbo Blower is one of the centrifugal type blower, which has 8 to 24 wings bent backward on the wings and is also called a silent fan. There is a casting type and a non-casting type casting, and a non-casting type casting is used for the air agitating blower of the plating bath. In addition, it is widely used for various applications such as forced ventilation of boilers and gas pressure feeding.

The turbo blower features low noise and 30% higher efficiency than conventional volumetric blowers because it employs a centrifugal compression method with good compression efficiency and employs a high speed motor that is variable by the inverter to be. That is, since the capacity of the turbo blower varies depending on the usage load, an additional power saving effect can be obtained.

The turbo blower can be operated in two modes: constant speed operation mode and proportional control mode. The constant speed operation mode is the operation mode in which the user sets the motor rpm to obtain the desired pressure and air flow rate, and the proportional operation is the operation in which the turbo blower automatically adjusts the motor rpm according to the target pressure and the desired pressure and air volume Mode.

More specifically, when the motor rpm is set to a first value (for example, rpm1) as shown in FIG. 1, the constant speed operation mode is automatically operated according to the first constant speed operation line, The suction temperature, the discharge pressure) is changed, the user can change the motor rpm to the second value (for example, rpm2) and change the operating point to the second constant speed operating line. That is, the constant speed operation mode is most widely used because it has the advantage of moving the operating point of the turbo blower according to the user's requirement, but it has a disadvantage that the turbo blower can be operated in a severe environment depending on the user and the surrounding environment .

In the proportional control mode, as shown in FIG. 2, after the operating point of the turbo blower is determined according to the turbo blower pressure, the operation point is moved according to the proportional control line, and the motor RPM is varied according to the discharge air amount. However, if the suction temperature is more than 40 degrees as in the summer, the actual air flow is reduced and sufficient oxygen can be supplied to the turbo blower. In this case, the turbo blower can operate ideally, but the drawback have.

As described above, in the conventional turbo blower, the operation point is moved only by using the pressure only in the constant speed operation mode, and when the proportional control mode is used, the operation point is moved by using only the air volume. (Refer to Korean Patent Application No. 10-2008-0023331).

The inverter 40 is electrically connected to the motor of the turbo blower 100 to adjust the rotational speed of the motor, thereby adjusting the amount and speed of the air blown by the blower 130.

FIG. 6 is a detailed block diagram of a control unit of an operation control apparatus for a turbo blower according to an embodiment of the present invention. Referring to FIG.

6, the control unit 30 includes an operation mode determination unit 31, a constant speed operation unit 32, a proportional control unit 33, a mixing control unit 34, 34 may include an operation environment monitoring unit 341, an operation line recommendation unit 342, an operation line adjustment unit 343, and the like.

Hereinafter, the function of each component will be described in greater detail.

The operation mode determination unit 31 configures an operation mode selection menu and provides the operation mode selection menu to the user, and determines one of the constant speed operation mode, the proportional control mode, and the mixed control mode as the operation mode of the operation control device in response to the user input.

The constant speed operation portion 32 is activated when the operation mode of the operation control device is the constant speed operation mode. This receives the motor RPM value from the user. Then, the turbo blower is automatically operated so that the air flow rate (or discharge flow rate) is variable according to the discharge pressure while maintaining the inputted motor RPM value. That is, after determining the operating point based on the motor RPM input by the user, the operating point is moved on the operating line of FIG.

However, if the discharge pressure deviates from the preset range, the user is notified of the current situation so that the user can perform the motor RPM changing operation. That is, the user can change the operation line of the turbo blower according to the operating environment.

The proportional control unit 33 is activated when the operation mode of the operation control device is the proportional control mode. This receives the target pressure value from the user. The turbo blower is automatically operated so that the RPM of the motor is varied according to the discharge air flow rate (or discharge flow rate) while maintaining the input target pressure value. That is, after the operating point is determined based on the discharge pressure inputted by the user, the operating point is moved on the proportional control line of FIG.

The mixing control unit 34 is activated when the operation mode of the operation control device is the mixed control mode. This pre-sets and registers a plurality of proportional control lines as shown in FIG. And monitors the current operating environment of the turbo blower and allows the turbo blower to operate according to proportional control lines that satisfy both the pressure required by the user and the current operating environment among a plurality of proportional control lines. Also, the operation environment monitoring operation is continuously performed during the operation of the turbo blower. If the operation environment changes by more than a predetermined value (i.e., the allowable range), the proportional control line recommending operation is performed again, To be selected.

That is, the mixing control unit 34 of the present invention allows the product to maintain the most ideal driving state while sufficiently reflecting the requirements of the user.

To this end, the proportional control line setting unit 341 sets and registers a plurality of proportional control lines reflecting different operating environments.

When the mixed control mode is activated, the operation line recommendation unit 342 confirms the current discharge pressure through the sensing unit 20 and receives the target pressure value from the user. However, since the discharge pressure can be confirmed through the turbo blower drive, when the operation line recommendation operation is performed before the turbo blower drive, the turbo blower is driven to house and the discharge pressure at this time is sensed. Then, based on the discharge pressure and the target pressure value, the current operating environment is grasped, and a proportional control line suitable for the operating environment is selected and recommended to the user.

If the user selects a recommended proportional control line, the operation line adjustment unit 343 causes the turbo blower to operate based on the proportional control line selected by the user. That is, the target pressure value input by the user is maintained, and the operating point of the turbo blower is moved on the proportional control line selected by the user.

On the other hand, if the user rejects the selection of the recommended proportional control line, the operating line recommender 342 re-recommends the proportional control line that is closest to the proportional control line and is more suitable for the current operating environment. If the user again rejects the proportional control line selection despite the re-recommendation operation of the proportional control line, the operation line recommendation unit 342 calls the operation mode determination unit 31 so that the user can select a new operation mode .

8 is a view for explaining a method of controlling an operation of a turbo blower according to an embodiment of the present invention. However, in FIG. 8, the constant speed operation mode and the proportional control mode of the present invention are based on the conventional technology, and a description thereof will be omitted.

If the user sets the mixed control mode through the user interface unit (S1), the operation control unit acquires the target pressure value through the user interface unit, and at the same time, acquires the current driving environment (that is, (S2). ≪ / RTI >

Then, among the plurality of proportional control lines previously registered, the proportional control line satisfying the target pressure value and satisfying the current driving environment is selected and recommended to the user (S3).

If the user accepts the recommended proportional control line through step S3 (S4), the operation point of the turbo blower is moved on the proportional control line, and the turbo blower is automatically operated. That is, the target pressure value is maintained, but the motor RPM is varied according to the air flow rate (or flow rate) (S5).

Then, the current driving environment is continuously monitored through the sensing unit 20, and if the current driving environment is changed beyond the preset value, that is, the allowable range or more, The control line is recommended (S6).

However, if the proportional control line is continuously rejected for a predetermined number of times (N, N is a natural number equal to or greater than 2) (S7), the operation mode changing operation is performed to allow the user to select a new operation mode (S8).
