The total heat exchanger 330 is a well-known and widely used in the building air conditioning field. When the indoor air is ventilated, the desiccator 335 stores the heat of the air discharged from the room to the outside, and the desiccator 335 ) Is a kind of heat exchanger that prevents heat loss by supplying heat to the air supplied from outside to the room. In the newly constructed apartment, such a heat exchanger 330 is mandatory.

Here, the desiccator 335 is coated with a zeolite having a dehumidifying function and an adsorbent therein to absorb and remove moisture contained in the air passing therethrough to provide comfortable air.

A feature of the present invention is that each sensor 325, 327, 329 installed in the ventilation diffuser 310 of the room when the air in a specific room (A) is contaminated by interlocking the ventilation diffuser 310 and the total heat exchanger 330 ) To detect the contaminated condition, and the dampers 39, 343, 347, and 351 of the total heat exchanger to open and close the air inlet properly to purify the air accordingly.

The operation (or control method) of the air conditioning system based on the data of the Korea Meteorological Administration and the data of the electric VV ventilation diffuser according to the present invention made as described above is as follows.

First, the meteorological agency forecasting terminal 100 collects the external air quality data of the area and sends the collected external air quality data to the user communication terminal 200.

Then, the user communication terminal 200 receives the external air quality data sent from the Korea Meteorological Administration and sends the received external air quality data to the user air conditioning device 300 installed in the building.

In addition, the user air conditioning device 300 receives external air quality data from the user communication terminal 200 and operates according to a control signal from the main control unit 320.

FIG. 3 illustrates a state in which the air quality of the user's room A is poor, and thus the air supply mode (a ventilator mode) in which the room A is rapidly ventilated.

First, the main communication unit 321 receives external air quality data of the Meteorological Agency from the user communication terminal 200 at any time, and then sends the received external air quality data to the main control unit 320.

The main control unit 320 receives the received external air quality data and stores it in real time. In addition, the main control unit 320 is pre-input and set the air quality data value, ie, the fine dust concentration reference value, the volatile organic compound (VOCs) concentration reference value, the temperature value, and the humidity value, which are the daily living standards.

The main control unit 320 is electrically connected to the diffuser control unit 323 and the total heat exchanger control unit 332 of the ventilation diffuser 310 to control them.

The diffuser control unit 323 sends a signal to each sensor 325, 327, 329 mounted on the ventilation diffuser 310 to detect the air quality of the room A.

Accordingly, the fine dust detection sensor 325 sends the detected fine dust concentration value to the diffuser control unit 323, and the diffuser control unit 323 sends the received fine dust concentration value to the main control unit 320.

The main control unit 320 compares the received fine dust concentration value with a preset fine dust concentration reference value, and if the received fine dust concentration value is greater than the preset fine concentration reference value, the air quality of the room A is poor, so the user The air conditioning device 300 is switched to an external air supply mode (a rapid ventilation mode).

As described above, to switch the user air conditioner 300 to the outside air supply mode (a ventilator mode), the main control unit 320 controls the signal to the diffuser control unit 323 of the ventilation diffuser 310 installed in the contaminated room (A). To send. Accordingly, the diffuser control units 323 of the two ventilation diffusers 310 responsible for air discharge and air inflow of the contaminated room A drive each motor 331 so that the damper 333 opens the passage 312. All ventilation diffusers 310 in the other room that are open and uncontaminated block the passage. Then, only the passage 312 of the ventilation diffuser 310 of the contaminated room A is opened, so that contaminated air in the room A is ventilated to the outside and air can be supplied to the room A as fresh outside.

At the same time, the main control unit 320 sends a control signal to the total heat exchanger control unit 332 of the total heat exchanger 330. In accordance with this signal, the total heat exchanger control unit 332 operates the external air damper 339, the exhaust damper 343, the air supply damper 347, and the ventilation damper 351.

Therefore, the outside air damper 339 opens the outside air supply port 337 according to the control signal of the total heat exchanger control unit 332, and the exhaust damper 343 also opens the exhaust port 341. In addition, the air supply damper 347 opens the air supply port 345, and the ventilation damper 351 also opens the air supply port 349.

In addition, the total heat exchanger control unit 332 drives the desiccator 335, the exhaust fan 355, and the air supply fan 353 according to the signal from the main control unit 320.

Accordingly, all the dampers 339, 343, 347, 351 of the total heat exchanger 330 and the passages 312 of the ventilation diffusers 310 of the contaminated room A are all opened, and the exhaust fan ( 355) and the air supply fan 353 are driven to move the air, and the desiccator 335 exchanges heat with the moving air, so it is switched to an external air supply mode (a rapid ventilation mode).

Therefore, the driven exhaust fan 355 pushes the air in the contaminated room (A) through the passage 312, the desiccator 335, and the exhaust port 349 of the ventilation diffuser 310 responsible for air discharge. The air supply fan (353) that discharges to the outside and also drives fresh air outside to supply air (337), desiccator (335), air supply (345), and ventilation diffuser (310) in charge of air inflow Through the passage 312 of the supply to the contaminated room (A) to purify the room.

In more detail, the external air supply mode (rapid ventilation mode) describes, the indoor air in the contaminated room (A) is passed to the passage 312 of the ventilation diffuser 310 in charge of air discharge by the pressure of the exhaust fan 355. After entering and entering the exhaust port 341 of the total heat exchanger 330, the heat exchanger proceeds through the internally designated flow path of the total heat exchanger 330 through the desiccator 335 to move to a lower temperature, and then the ventilation port 349 Is discharged through the outside. At the same time, fresh outside air flows into the outside air supply port 337 opened by the pressure of the air supply fan 353, passes through the internal first filter 357 of the heat exchanger 330, and then passes through the designated flow path. Ventilation diffuser (310) responsible for air inflow into the contaminated room (A) after being discharged to the air supply (345) in a heated state by performing heat exchange to absorb heat of the air discharged to the outside from the secanter (335) ) Passage 312 is discharged to purify the air in the room (A).

Therefore, the air in the contaminated room (A) is discharged to the outside, and fresh outside air is supplied to the room (A) and filtered while passing through the first filter to be supplied to the room (A) while the fine dust is significantly reduced. (A) is immediately purified and becomes a pleasant environment.

When the filtered outside air is supplied to the room (A) for a long time as described above, the air in the room (A) is rapidly reduced in fine dust, and when its fine dust concentration is lowered to match the preset fine dust concentration value, the outside air supply mode (rapid Ventilation mode) is finished.

On the other hand, the concentration of volatile organic compounds (VOCs) detected by the VOCs sensor 327 is higher than the reference value of the concentration of volatile organic compounds (VOCs) set in the main control unit 320, and the room (A) is contaminated with volatile organic compounds (VOCs). Even in this case, the user air conditioning device 300 is switched to an external air supply mode (a rapid ventilation mode).

That is, the main control unit 320 sends a control signal to the diffuser control unit 323 of the ventilation diffuser 310. In addition, the diffuser control unit 323 sends a control signal to the VOCs detection sensor 327. The VOCs detection sensor 327 detects a volatile organic compound in the air of the room (A) according to a control signal from the diffuser control unit 323 and sends the detected volatile organic compound concentration value to the diffuser control unit 323.

The diffuser control unit 323 sends the received volatile organic compound concentration value to the main control unit 320. The main control unit 320 compares the received volatile organic compound concentration value with a preset volatile organic compound concentration value, and if the received volatile organic compound concentration value is greater than the preset volatile organic compound concentration value, the user air conditioning device 300 Switch to the external air supply mode (rapid ventilation mode).

When switching to the emergency ventilation mode as described above, the main control unit 320 sends a control signal to the diffuser control unit 323 of the ventilation diffuser 310. In addition, the diffuser control unit 323 sends a control signal to the motor 331. The motor 331 is driven according to the control signal of the diffuser control unit 323 to operate the damper 333 to open the passage 312.

Then, the main control unit 320 sends a control signal to the heat exchanger control unit 332 of the heat exchanger 330. The total heat exchanger control unit 332 sends control signals to the outside air damper 339, the exhaust damper 343, the air supply damper 347, and the ventilation damper 351.

The outside air damper 339 opens the outside air supply port 337 of the heat exchanger 330 according to the control signal from the heat exchanger control unit 332, the exhaust damper 343 opens the exhaust port 341, and the air supply damper 347 ) Opens the air supply port 345, and the ventilation damper 351 opens the ventilation port 349.

Then, the total heat exchanger control unit 332 sends a control signal to the exhaust fan 349.

The exhaust fan 349 heats the contaminated air in the room A, that is, the air through the passage 312 and the desiccator 335 of the ventilation diffuser 310 according to the control signal of the total heat exchanger control unit 332 It is sent to the ventilation port 349 of the exchanger 330. Accordingly, the total heat exchanger 330 discharges the contaminated room (A) air heat-exchanged from the desiccator 335 through the ventilation port 349 to the outside.

At the same time, the total heat exchanger control unit 332 sends a control signal to the air supply fan 353. The air supply fan 353 sends fresh outside air to the passage 312 of the ventilation diffuser 310 through the outside air supply port 337 and the desiccator 335 according to the control signal of the heat exchanger control unit 332. Accordingly, the ventilation diffuser 310 supplies the outside air heat-exchanged from the desiccator 335 into the room A through the passage 312.

In summary, the indoor air in the room (A) contaminated by volatile organic compounds (VOCs) flows into the passage 312 of the ventilation diffuser 310 responsible for air discharge by the pressure of the exhaust fan 355. After entering the exhaust port 341 of the total heat exchanger 330, the heat exchanger proceeds through the heat exchanger in the desiccator 335 after passing through the internally designated flow path of the total heat exchanger 330, and then moves to a lowered temperature and then through the ventilation port 349. It is discharged outside. At the same time, fresh outside air flows into the outside air supply port 337 opened by the pressure of the air supply fan 353 and then passes through the internal first filter 357 of the total heat exchanger 330, and then the desiccator 335 ) Is discharged to the air supply 345 in a heated state by performing heat exchange to absorb heat of the air discharged to the outside, and then the passage of the ventilation diffuser 310 responsible for air inflow into the contaminated room (A) ( 312) It is discharged and purifies the air in the room (A).

Therefore, the air in the room (A) contaminated by volatile organic compounds (VOCs) is discharged to the outside, and fresh outside air is filtered through the first filter while being supplied to the room (A), so that the volatile organic compounds (VOCs) are Since it is supplied to the room (A) in a significantly reduced state, the room (A) is immediately purified and becomes a pleasant environment.

When the filtered outside air is supplied to the room (A) for a long time as described above, the air in the room (A) is rapidly reduced in volatile organic compounds (VOCs), and its volatile organic compounds (VOCs) concentration is preset to volatile organic compounds (VOCs). When the concentration is lowered to coincide with the value, the external air supply mode (feed ventilation mode) ends.

On the other hand, even if the temperature and humidity of the room (A) air is higher than the temperature and humidity reference values set in the main control unit 320 by the temperature and humidity detected by the temperature and humidity sensor 329, the user air conditioner 300 It is switched to the external air supply mode (rapid ventilation mode).

That is, the main control unit 320 sends a control signal to the diffuser control unit 323 of the ventilation diffuser 310. In addition, the diffuser control unit 323 sends a control signal to the temperature and humidity sensor 329. The temperature and humidity sensor 329 detects temperature and humidity in the air of the room (A) according to the control signal of the diffuser control unit 323 and sends the detected temperature and humidity detection values to the diffuser control unit 323.
