And, the ends of the air supply and exhaust duct (DUCT) for each room (ROOM 1,2,3,4) is coupled to the electric diffuser (D1 ~ D8) for the individual adjustment of the supply and exhaust amount, the electric diffuser is a cylindrical tube-shaped body ( 50 is provided, the support 51 is formed inside the main body, the rotation shaft 52 is coupled to the center of the support to move up and down is formed to be driven by the linear stepping motor 54, the linear stepping The motor 54 is fixed to the support 51, the cover 55 is formed on the support On the other hand, the extraction cone 53 is formed in the lower portion of the rotary shaft 52 so as to seal the lower portion of the main body 50 is opened, the linear shaft stepping motor to raise and lower the rotary shaft 52, combined with the rotary shaft (53) ) Is interlocked with the set height (0 ~ 3cm) is formed to open and close the body 50.

In addition, the electric diffuser is opened and closed so that the discharge cone 53 of the diffuser is selectively up and down by a wall pad or a remote control circuit (485 communication) of the room controller (C) to adjust the individual air supply and exhaust amount for each room. It is desirable to be formed to be.

[Example]

The present invention, as shown in Figure 4, by installing a temperature sensor and a pressure sensor in the electric diffuser (indoor finishing material of the supply and exhaust line) that is a terminal unit to adjust the air volume by individually up and down the internal blower cone It is formed to control the temperature and the strength of the air.

That is, this can be done by using electric diffusers D1, D2, D3, D4, D5, D6, D7, and D8 at the respective duct ends.

At this time, the pressure sensor formed on one side of the electric diffuser checks the pressure at which air is introduced to operate (open and close) the diffuser, and checks the temperature, if the temperature of the air is lower than the set temperature in summer, the position of the blowout cone is leveled. Increase the cooling efficiency by allowing air to be discharged horizontally by setting it to a blowout type. On the contrary, if the air temperature is higher than the set temperature in winter, the blower cone is set to the vertical blowout type to discharge the air vertically. Overall, the heating and cooling efficiency is formed to maximize.

In addition, the pressure sensor formed on the other side of the electric diffuser also checks the air inflow pressure with respect to the wind intensity, and if the air pressure is higher than the set pressure, the air volume of the air supply fan is adjusted (rotation speed or voltage adjustment). In order to reduce the amount of blown out, on the contrary, when the pressure of the inflowing air is low, it is preferable that the amount of blown air is adjusted to increase the amount of blown out air.

Of course, the above-described electric diffuser enables its own temperature sensor and pressure sensor to be individually operated in each room, as well as the temperature sensor and the pressure sensor of the drive circuit on the heat exchanger side, the wall pad and the room controller of each room. It is preferable to be controlled remotely by a remote control.

At this time, looking at the electric diffuser in more detail, a support 51 for fixing the linear stepping motor 54 inside the main body 50 is installed.

At this time, the linear stepping motor 54 is formed to move the shaft through the inside.

In this case, the motor cover 55 is preferably manufactured in a hemispherical shape in which the linear stepping motor 54 may be protected and wind movement may be advantageous.

At this time, the blowout cone 53 is made of a rod having a threaded shape that can be connected to the linear stepping motor 54 and made in a streamline so that the wind moves naturally, combined with the linear stepping motor 54 to the rotational force of the motor As the blower cone rotates up and down, the air volume is adjusted. At this time, it is possible to adjust the direction of the wind by adjusting the height of the blowout cone.

In other words, according to the principle that the hot air goes up and the cold air sinks due to the nature of the air, the cooling cone is moved to the upper part during the cooling in summer, so that the cooled air can be taken out horizontally, and the cooling out in the winter heating. The cone can be moved to the bottom to draw hot air vertically to maximize cooling and heating.

In addition, the upper portion of the blowout cone is made to be completely in contact with the main body using a soft material.

In this way, all the positions using the electric mechanism should be installed to check the A / S so that the use of the electric diffuser has the advantage that can be easily and simply A / S by separating only the main body.

That is, the method using the electric diffuser can reduce the construction cost by eliminating the need for an inspection port, which is advantageous in interior.

In addition, as the blocking plate of the electric damper is completely closed by the extraction cone to block the transmission of noise to the neighboring room through the supply and exhaust duct.

In other words, the air supply and exhaust system using the electric damper actuator and the electric diffuser is composed of a unit and a supply and exhaust duct, as shown in Figure 4, the unit is an electric damper (M9) on the exhaust of the electric damper (M9) on the air supply Is installed inside the unit, and the electric damper (M11) for supply / exhaust by pass of the mixing box is installed, and the supply and exhaust ducts (DUCT) are installed for each room (ROOM 1, 2, 3, 4). Each electric diffuser D1 to D8 is installed in the duct.

At this time, the electric diffuser of each room is connected to MAIN BOARD, and ID is obtained by splitting the code by RS-485 from the board (D1 ~ D8, M9, M10, M11) and the home network wall pad or room When the signal from the controller (ROOM CONTROLLER) is transmitted to the main board, the code is divided into each diffuser on the main board and the signal is transmitted and operated by the signal. Therefore, the signal transmission is performed by RS-485.

When the unit is operated and the pressure of air supply and exhaust is detected, each diffuser is closed and opened, and when the temperature difference is detected by heating and cooling, horizontal and vertical ejection are automatically performed. Lose

For example, assuming that the required air volume of the entire room is 100 CMH and the proper air flow rate for each room is 25CMH for each supply and exhaust.

1) If the amount of air supply and exhaust for each room is 20 CMH, adjust the diffuser accordingly to supply 20 CMH for each room, and the total amount of 80 CMH is required. Alternatively, by adjusting the voltage of the supply / exhaust fan of the unit according to the signal of the WALL PAD (ROOM CONTROLLER), the air volume of the supply / exhaust fan of the unit can be adjusted, thus reducing the operating cost. Can be reduced.

At this time, the diffusers (D1--D8) of each chamber and the supply / exhaust actuators (M9, M10) on the unit show a crush rate of 80% each.

2) In case of ROOM 1, 25 CMH R00M 2 needs 12,5 CMH supply and exhaust, and ROOM 3, 4 needs 37,5 CMH in total when there is no need for supply and exhaust. Alternatively, by adjusting the voltage of the supply / exhaust fan of the unit according to the signal of the WALL PAD (ROOM CONTROLLER), it is possible to reduce the operating cost by adjusting the air volume of the supply / exhaust fan of the unit. Can be reduced.

At this time, the diffuser (D1, D2) of ROOM 1 is 100%, the diffuser (D3, D4) of ROOM 2 is 50%, the diffuser (D5, D6, D7, D8) of ROOM 3, 4 is 0%, and the unit's actuator ( M9, M10) shows an opening and closing rate of 37,5%.

In addition, by switching the amount of exhaust gas to supply air by operating the damper for BY PASS of M11, the amount for supplying air can be reduced.

That is, it means the reuse of the energy of indoor air to be discharged.

In this way, by individually supplying and supplying exactly the required amount of exhaust air in each room, it is possible to reduce the operating cost of the unit and reduce the energy required for heating and cooling by reducing unnecessary supply and exhaust.

In addition, in the past, each diffuser was opened, closed, horizontally and vertically taken out by heating and cooling only by the signal of WALL PAD (ROOM CONTROLLER), but this electric diffuser keeps the state automatically by using the sensor. Also possible with PAD operation)

On the other hand, the present invention, when using the electric damper for the HVAC unit of the apartment house, as shown in Figure 5, to form an actuator for precisely driving the internal blocking plate of the electric damper at a set angle, the actuator is RS-485 allows the linear stepping motor to be precisely operated (controlled) at a set angle, as well as to allow manual operation by a separate volume knob.

Thus, the actuator of the present invention, as shown in Figures 6 to 7, step-down circuit 100, rectifier circuit 200, constant voltage circuit 300, the central processing unit 400, motor control circuit 500, power storage circuit 600, the stepping motor driving circuit 700, the manual operation circuit 800 and the remote control circuit 900 is large.

At this time, the step-down circuit 100 is a stepping motor 6 is installed on the circuit board, and when the power is applied to configure a filter (preventing abnormal power supply) using the surge prevention TNR1 and the capacitor (C3), The resistors R1 and R2 and the capacitor C1 are configured to bring down the voltage AC 220V. At this time, the down voltage is preferably 12V.

Accordingly, the rectifier circuit 200 has rectification diodes D1, D2, D3, and D4 to convert the AC voltage AC, the voltage of which is down through the step-down circuit, to a direct current DC.

Accordingly, the constant voltage circuit 300 includes a plurality of xenodiodes and capacitors ZD1, C3 / ZD2, and C8 so that the DC voltage converted from the rectifier circuit maintains a constant voltage.

At this time, 12V is maintained at the (ZD1, C3) side and 5V is maintained at the (ZD2, C8) side of the xenodiode and capacitor.

Accordingly, the CPU 400 is driven by the voltage supplied from the constant voltage circuit.

At this time, the motor control circuit 500 is driven by the IC (U3) so that the stepping motor is controlled by receiving a signal from the central processing unit.

In addition, the central processing unit 400 is configured to receive power from the power storage circuit 600 at all times, as shown in FIG. 7, but is idling by receiving a signal value to use the lowest power when power supply is interrupted including an emergency. It is preferable that the idling circuit 410 is further provided to be switched to the mode (power strategy mode).

In other words, such an idling mode or a power strategy mode minimizes continuous power loss only when a minimum emergency power is applied when a power supply is interrupted, which means that a signal generated through a separate idling circuit 410 checks a power supply state. In addition, when the power is closed and the battery is used at the same time, the central processing unit is configured to operate by switching the set value to the minimum power use mode.

Thus, the power storage circuit 600 is provided with a rechargeable storage battery (C4 ~ C7) to use the power supplied from the constant voltage circuit in an emergency including a power failure. Such a battery is formed to return to its original home position in an emergency other than in an emergency mode.

At this time, when the power is applied from the constant voltage circuit, the stepping motor driving circuit 700 drives the IC U3 by the command of the central processing unit, and simultaneously rotates the stepping motor 6 at the set rotation angle (90 °). It is formed to rotate the blocking plate according to the programmed angle.

That is, the stepping motor 6 is capable of precise angle control and speed control, which is used as a motor that is optimized for the individual air-conditioning and exhaust air supply system described below.

In other words, unlike the conventional limit switch contact method (only the opening / closing of the blocking plate according to the forward and reverse rotation), the stepping motor is easy to control the communication by the home network, as well as precise angle adjustment and speed adjustment, thereby improving thermal efficiency. There is a feature to improve.

In addition, the manual operation circuit 800 is interlocked with the motor control circuit, the volume knob (VR1) is provided so that the electric damper actuator is manually adjusted to any one of any angle within the set 0 ~ 90 ° radius.

That is, the volume knob is formed to operate the angle of the blocking plate simply by adjusting the stationary motor from the outside without a cumbersome assembly using a separate tooth tool in order to move the lever to the set angle in case of emergency.

Accordingly, the remote control circuit 900 is driven by the IC (U2) by the home network (RS-485 communication) so that the central processing unit including the motor control circuit is remotely controlled to the stepping motor at any angle between 0 ~ 90 ° It is configured to be adjusted.

That is, the remote control circuit is formed to control the rotation angle of the actuator by a separate remote controller or a wireless communication method in addition to the room controller.

In other words, the air volume is controlled by adjusting the angle of the damper using the actuator, and the air supply and exhaust duct becomes the passage for the movement of noise, and the transmission of the noise is closed by closing the damper.
