The exhaust diffuser 110 and the air supply diffuser 120 are electric diffusers that can be opened and closed by a switch. The exhaust diffuser 110 and the air supply diffuser 120 are connected to the corresponding exhaust pipe 130 and the air supply pipe 140, respectively, and are installed in a plurality of indoor spaces. Here, the indoor space means, for example, an independent space divided into a wall and a door even in an indoor room such as a living room, a bedroom, a bedroom 1, a bedroom 2, and the like.

Exhaust diffuser 110 and the air supply diffuser 120 according to an embodiment of the present invention are each open or closed signal (hereinafter referred to as open and close signal) according to the operation for ventilation, the open and close signal includes an open signal and a closed signal. ) Can be generated and delivered to the controller 160, which will be described in detail later.

The exhaust pipe 130 is an air passage for transferring indoor air sucked from the plurality of exhaust diffusers 110 to the heat exchanger 150, and the air supply pipe 140 supplies a plurality of air to the outdoor air sucked from the heat exchanger 150. Air passage to the diffuser 120.

The total heat exchanger 150 sucks indoor polluted air for indoor ventilation and exhausts it to the outside, and purifies and heat-exchanges outdoor fresh air with a filter and supplies it to the indoor, and exhaust fan for exhausting indoor air ( 151 and an air supply fan 152 for supplying outdoor air.

The exhaust fan 151 is connected to the end of the exhaust pipe 130 to suck indoor polluted air and discharge it to the outside, and the air supply fan 152 sucks outdoor air and supplies it to the room through the air supply pipe 140. do. In addition, the heat exchanger 150 further includes an apparatus for driving a fan, and so may use a technique known at the time of filing the present invention, and thus detailed description thereof will be omitted.

The controller 160 stores data about the required air volume of each indoor space in a memory, and receives an opening / closing signal from the exhaust diffuser 110 and the air supply diffuser 120 provided in the indoor space to receive an open signal. The total exhaust air flow rate and the air supply air flow rate are calculated by adding the required air volume weights of the spaces. Then, the output size of the exhaust fan 151 and the air supply fan 152 is controlled according to the calculated total exhaust air amount and the air supply air amount. In addition, when the controller 160 receives the closing signals from the specific exhaust diffuser 110 and the air supply diffuser 120, the controller 160 controls the output size by subtracting the required air volume of the corresponding indoor space from the total exhaust air flow and the air supply air flow.

Here, the data on the required air volume may be the volume of each indoor space, and in general, since the interior spaces of the living room, the inner room, the bedroom 1, and the bedroom 2 are different in volume, the required air volume for ventilation is also different from each other.

According to Article 11 of the Rules on the Equipment Standards of Buildings, etc., Article 11 (Standards for Ventilation Facilities for Shared Housing and Multi-use Facilities, etc.) (1) Housings falling under any of the following subparagraphs newly built or remodeled in accordance with Article 87 (2) Or buildings (hereinafter referred to as "new apartment buildings") shall be equipped with natural ventilation equipment or mechanical ventilation equipment to provide ventilation of at least 0.7 times per hour. '

Here, 0.7 times per hour means that the air corresponding to 70% of the volume of the room should be ventilated for one hour, and the heat exchanger 150 vents at least 70% of the total volume of all indoor spaces in the household per hour. Fan output is possible.

The controller 160 inputs a volume according to the size of each indoor space, wherein the required air flow is, for example, a room 5 m, a vertical 4 m, and a height of 3 m. Means the amount of air to ventilate.

Accordingly, the controller 160 may determine the exhaust fan 151 as the total air supply / exhaust air volume by adding weights of the required air volume based on the open signal of the exhaust diffuser 110 and the air supply diffuser 120 and the volume of each corresponding indoor space. The output of the air supply fan 152 may be adjusted.

On the other hand, the electric diffuser according to an embodiment of the present invention is divided into an exhaust diffuser 110 and an air supply diffuser 120 according to the use connected to the exhaust pipe 130 or the air supply pipe 140, the detailed configuration of the exhaust diffuser An example of 110 is described with reference to FIG. 2.

2 is a block diagram illustrating a configuration of an exhaust diffuser according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the exhaust diffuser 110 according to the embodiment of the present invention includes an exhaust port 111, a blocking film 112, a motor 113, a switch 114, and a control module 115.

Exhaust port 111 is an air passage (vent) for inhaling indoor air to exhaust pipe 130 for ventilation.

The blocking film 112 forms a film for opening or closing the air passage of the exhaust port 111 by the power. That is, when the blocking film 112 is opened, the air is ventilated by suctioning the indoor air, and when the blocking film 112 is closed, the suction is stopped and the ventilation is stopped.

The motor 113 transmits power for opening or closing the blocking film 112 according to the control signal.

The switch 114 generates a switch ON / OFF signal by turning on and off according to the necessity of ventilation of an independent indoor space such as a living room or a room, such as a switch of a light.

The control module 115 transmits a control signal to the motor 113 according to the on / off signal of the switch 114 to control the opening / closing operation state of the blocking film 112, and controls the opening / closing signal of the blocking film 112 to the controller 160. To pass).

As described above, the air supply diffuser 120 differs only in that it is connected to the air supply pipe 140 in the same structure as the exhaust diffuser 110. Therefore, the air supply diffuser 120 also supplies fresh air to the indoor space when the blocking film is opened, and the ventilation is made. When the blocking film is closed, the air supply is stopped and the ventilation is stopped.

On the other hand, Figure 3 shows a control structure of the exhaust diffuser and the air supply diffuser according to an aspect of the present invention.

Referring to FIG. 3, in FIG. 2, the exhaust diffuser 110 and the air supply diffuser 120 have independent control configurations, while in FIG. 3, the exhaust diffuser 110 and the air supply diffuser 120 control signals. Shows the status of a shared pair.

In general, when the exhaust diffuser 110 installed in the same indoor space is opened, indoor air is sucked to generate a negative pressure, and when the air supply diffuser 120 is opened, outdoor air is introduced to generate positive pressure. Therefore, for efficient ventilation, the exhaust diffuser 110 and the air supply diffuser 120 may be operated at the same time. Therefore, when operating the exhaust diffuser 110 and the air supply diffuser 120 through one control means as shown in Figure 3 there is an advantage that can perform efficient ventilation while reducing the device.

On the other hand, Figure 4 shows a configuration for controlling the exhaust diffuser and the air supply diffuser based on the detection signal in accordance with an aspect of the present invention.

In FIGS. 2 and 3, when the switch 114 generates an on / off signal and is manually ventilated according to the ventilation needs of the occupants, FIG. 4 automatically exhausts the diffuser according to a control condition based on the detection signal of the sensor. The control point 110 and the air supply diffuser 120 are different.

Referring to FIG. 4, the ventilation amount control system 100 according to an exemplary embodiment of the present invention further includes a motion detecting unit 170 and an air measuring unit 180.

The motion detection unit 170 transmits a presence detection signal of the occupant in the indoor space to the control module 115.

At this time, when the control module 115 receives a detection signal in which the occupant is present in the indoor space, the control unit 115 opens the corresponding diffuser to perform ventilation, and if the occupant does not exist, closes the corresponding diffuser to stop the ventilation. As in the case of the on / off signal of the switch 114 described above, the automatic operation is performed by transmitting the open / close signal to the controller 150.

In recent years, the apartment building, which is being built, is equipped with a home automation system that includes security functions using various sensors, as well as automating home and household life using various electronic equipment.

The motion detection unit 170 uses a motion detection sensor that detects an intruder's motion for a crime prevention function in a home automation mode, and enables automatic ventilation without additional equipment.

On the other hand, multi-family housing may cause respiratory and skin diseases of residents due to various harmful materials generated from various building materials and indoor furniture. Therefore, many people are reluctant to move in due to sick house syndrome for many years, and have received a new house syndrome removal work or purchase an air cleaner before moving in, but the effect is insignificant compared to the costs incurred.

In particular, the above described a method of automatically operating by detecting the user's rehabilitation, but when the user is going out for a long time, when the user returns home and enters the room, there is a problem that causes unpleasantness due to the polluted air in the room due to the absence of ventilation. have.

The air measuring unit 180 according to an aspect of the present invention is a sensor for measuring the pollution degree of indoor air to measure the pollution degree of at least one of formaldehyde, volatile organic compounds, and carbon to the control module 115 to measure the pollution degree information. send.

The control module 115 opens the diffuser of the corresponding indoor space for a predetermined time and transmits an open signal to the controller 150 when the pollution degree measurement information received in the home automation mode is exceeded and the reference value is exceeded.

The controller 160 operates the heat exchanger 150 by calculating the required air volume according to the open signal.

According to the embodiment of the present invention, the opening and closing operation of the exhaust diffuser 110 and the air supply diffuser 120 installed in the indoor space is the on / off signal of the switch 114, whether the presence of the occupant of the motion detection unit 170 It was described as being controlled based on the detection signal and the pollution degree measurement information of the indoor air of the air measurement unit 180. In the operation of the ventilation amount control system 100, the signals / information based on the above-described signals may be individually applied as described above, and may be applied to be interoperable with each other.

Therefore, the method for controlling the ventilation amount of the room according to the embodiment of the present invention will be described with reference to FIGS. 5 to 7 below, assuming that it is linked to the manual mode, the automatic mode, and the outing mode.

In addition, it is assumed that the exhaust diffuser 110 and the air supply diffuser 120 are operated by one switch 114 and the control module 115 as shown in FIGS. 3 and 4, but is not limited thereto.

A surface switch ON signal is generated (S101), and the blocking film 112 is opened according to the control signal of the control module 115 (S102). The control module 115 transmits an open signal of the exhaust / air supply diffuser to the controller 160 (S103).

When the controller 160 receives the opening signal of the exhaust / air supply fuser, the controller 160 confirms that the object is, for example, a living room, based on the communication port or identification information in the data stored in the memory, and grasps the required air volume according to the volume. (S104).

The controller 160 calculates the total exhaust air flow rate and the air supply air flow amount by adding the grasped required air flow amount to the current air flow amount (S105), and controls the output by reflecting this to the exhaust fan 151 and the air supply fan 152 ( S106). Here, when the heat exchanger 150 is stopped, the operation of the heat exchanger 150 is started with the output as much as the required amount of wind.

Thereafter, the exhaust / air supply diffuser 110/120 of the ventilation amount control system 100 generates a switch OFF signal when the switch 114 of the living room is turned off by the occupant (S107), and controls the control module 115. The blocking film 112 is closed in response to the signal (S108). In addition, the control module 115 transmits the closing signal of the exhaust / air supply diffuser to the controller 160 (S109).

When the controller 160 receives the closing signal of the exhaust / air supply fuser, the controller 160 determines the required air volume according to the volume of the living room as described above (S110). Subsequently, the required required air volume is subtracted from the currently output air volume to calculate the total exhaust air volume and the air supply air volume (S111), and the output is controlled by reflecting this to the exhaust fan 151 and the air supply fan 152 (S112). At this time, if the total exhaust air flow rate and the air supply air flow rate are zero, the operation of the heat exchanger 150 is stopped.

As a result, the blocking film 112 is opened (S204). The control module 115 transmits an open signal of the exhaust / air supply diffuser to the controller 160 (S205).

When the controller 160 receives the opening signal of the exhaust / air supply fuser, the controller 160 determines the required air volume according to the living room and its volume based on the communication port or identification information from the data stored in the memory (S206).

The controller 160 calculates the total exhaust air flow rate and the air supply air flow amount by adding the grasped required air flow amount to the current air flow rate (S207), and controls the output by reflecting it to the exhaust fan 151 and the air supply fan 152 ( S208).

Thereafter, the exhaust / air supply diffuser 110/120 of the ventilation amount control system 100 closes the blocking film 112 according to the control signal of the control module 115 when no occupants exist for a predetermined time, The operation of stopping ventilation by transmitting the closing signal to the controller 160 may be referred to as steps S107 to S112 of FIG. 5 described above, and thus a detailed description thereof will be omitted.
