During the ventilation operation as described above, when the air is supplied to the bypass interval 36 and the optical plasma generator 90 is driven, the virus or bacteria contained in the air passed while irradiating the UV light to the bypass interval 36 is removed. can be eradicated.

As described above, since the bypass interval 36 for passing the heating element 32 and the filter 34 individually is provided, the filtering operation of filtering outdoor air and supplying it to the room or circulating the indoor air is performed. When outdoor air or indoor air is supplied through only the anti-virus filter 34a and the filter 34 without passing through the heating element 32, the resistance and static pressure generated during air flow can be reduced to reduce power consumption. do.

The control method of the ventilation system communication type air conditioning unit integrated system according to an embodiment of the present invention configured as described above is as follows.

In accordance with an embodiment of the present invention, there is provided a method for controlling an integrated system for a ventilation device communicating type air conditioning unit, the method comprising the steps of: detecting the temperature of indoor air and determining whether the temperature of the indoor air is outside a set range to determine whether to start the air conditioning operation; When the temperature of the indoor air exceeds the set range, the cooling operation is started, and when the temperature of the indoor air falls below the set range, the heating operation starts according to the driving signal transmitted from the integrated control unit 100 to the heating/cooling unit ( 200) is driven to start heating and cooling operation, and when heating and cooling operation starts, the amount of carbon dioxide, fine dust, virus or formaldehyde in the room is measured to determine whether the amount of carbon dioxide, fine dust virus or formaldehyde exceeds the set value to determine whether to start the ventilation operation, and measuring the amount of carbon dioxide, fine dust, virus or formaldehyde in the room, and when the amount of carbon dioxide, fine dust virus, or formaldehyde exceeds the set value, it is transmitted from the integrated control unit 100 and a step of purifying indoor air while discharging or circulating indoor air to the outdoors by driving the ventilation device according to the driving signal.

Therefore, when the operation of the integrated system is started, ventilation operation, outdoor air cooling/heating operation, and internal cooling/heating operation are selected and started by measuring indoor temperature, outdoor temperature, the amount of fine dust contained in the indoor air, and the amount of fine dust contained in the outdoor air, and the electric heating element Condensation prevention operation can proceed by measuring the amount of moisture remaining in the

When the outdoor air cooling/heating operation or ventilation operation is started, as shown in FIG. 5, indoor air is supplied to the ventilation port 14 through the ventilation extension pipe 112, and passes through the bypass duct 76 to the outside through the exhaust port 16. The external air flows into the ventilation device through the outdoor port 12 and passes through the fifth space, bypassing the filter 34 and the heat transfer element 32 to the air supply pipe 18 and the connection passage 110. It is supplied to the plurality of heating and cooling units 200 through the outlet and is supplied into the room through the outlet 214 .

When it is determined that the amount of fine dust in the outside air exceeds the set value during the ventilation operation or outdoor air cooling/heating operation as described above, as shown in FIG. 12a) to remove fine dust contained in the outside air while passing through the filter 34, pass the bypass interval and the second damper 59, pass the bypass guide 70, and supply to the supply port 18, The outdoor air passing through the air supply port 18 is supplied to each heating/cooling unit 200 along the connection flow path 110 and discharged into the room.

When the cooling operation is started at the stage of starting the heating and cooling operation, and after the ventilation operation is started in the stage of determining whether to start the ventilation operation, when the temperature of the indoor air is measured to be higher than the set value compared to the temperature of the outdoor air, the integrated control unit 100 The cooling operation of the heating and cooling unit 100 is stopped according to the driving signal transmitted from the , and the turbo fan 216 of the heating and cooling unit is driven to supply external air to the room, and the ventilation operation and the heating and cooling operation are performed.

During the ventilation operation, when the temperature difference between the indoor temperature and the outside temperature is out of the set range and the cooling/heating operation is performed by heat exchange between the outside air and the inside air, as shown in FIG. In this state, the ventilation operation proceeds to conduct heat exchange between indoor air and outdoor air.

In this case, it is possible to prevent the heating and cooling unit 200 from being repeatedly driven by the operation of the integrated control unit 100 , so that it is possible to reduce the consumption of electric energy.

When the amount of outdoor fine dust is detected to be less than the set value during the ventilation operation or outdoor air cooling/heating operation as described above, the filter 34 can be bypassed by supplying the external air flowing in through the outdoor device 12 to the fifth space. It is possible to reduce the load of the supply fan 88a and the turbofan 216 while reducing the static pressure of the external air passing through the ventilation device, and the external supplied to the room while the supply fan 88a and the turbofan 216 are simultaneously driven. It is possible to increase the amount of air blown so that it is possible to reduce the electric energy consumption.

When the ventilation operation is finished after the step of purifying the indoor air of the present embodiment, the amount of fine dust or foreign matter accumulated in the filter 34 of the ventilation device is detected and the amount of fine dust or foreign material exceeds the set value, and the exhaustion operation is performed. In the step of determining whether to initiate It further includes a step of starting the exhaustion operation of discharging to the outdoors by passing the filter 34 in the reverse direction after supply at the bypass interval 36 .

Therefore, when the accumulated amount of fine dust or foreign substances accumulated in the filter 34 exceeds the set value, indoor air is supplied at a bypass interval and passes through the filter 34 in the reverse direction, and the fine dust or foreign substances accumulated in the filter 34 is discharged through the exhaust port ( 16) can be discharged to the outside.

In addition, in the step of determining whether to start the exhaustion operation in this embodiment, when the amount of fine dust or foreign substances accumulated in the filter 34 is measured below the set value and the exhaustion operation is completed, the moisture adsorbed to the electric heating element 32 of the ventilation device detecting the amount of water and determining whether the amount of moisture exceeds the set value to determine whether to start the anti-condensation operation It includes the step of starting the anti-condensation operation of supplying to (36) and removing moisture while passing the heating element (32).

When the moisture remaining in the heating element 32 exceeds the set value, as shown in FIG. 11 , after removing the moisture remaining in the heating element 32 while passing the heating element 32 after supplying indoor air at a bypass interval, circulated indoors.
