1 is a view for explaining an implementation example of an air conditioning system according to an embodiment of the present disclosure.

As shown in FIG. 1 , the air conditioning system 1000 includes the control device 100 , the ventilator 200 , the air conditioners 300-1 to 300-n, and the diffusers 400-1 to 400-n. include

The control apparatus 100 according to an embodiment of the present disclosure may control the operation of the ventilator 200 .

The control device 100 is an electronic device having a processor 130 , and settings related to the amount of air required for ventilation of the indoor space from each air conditioner 300-1 to 300-n and whether the ventilation operation of the current air conditioner is performed. receive information

The ventilator 200 is a device for introducing outdoor air into the room. An inlet (not shown) for connecting to the ventilator 200 may be included at one side of the air conditioner 300 . One side of the ventilator 200 may be connected to the inlet of the air conditioner 300 , and the other side may be connected to the ventilation pipe 600 .

Accordingly, the ventilator 200 may guide the external air introduced from the ventilation pipe 600 toward the air conditioner 300 .

The air conditioner 300 refers to an indoor unit having air cleaning and ventilation functions. A plurality of air conditioners 300 may be used, but may be installed and used alone. The air conditioner 300 may be implemented as a wall-mounted, ceiling-type, or stand-type indoor unit.

The air conditioner 300 may include a damper. The damper 310 is provided on one side of the air conditioner 300 to be connected to the ventilation pipe 600 , and may block the inflow of air from the ventilation pipe 600 .

Although the damper 310 according to an embodiment of the present disclosure is illustrated as a member having a flat cylindrical side surface and a rotatable opening/closing function, the shape of the damper 310 is not necessarily limited thereto.

The damper 310 opens when the user turns on the ventilation function of the air conditioner 300 , and closes when the user turns off the ventilation function of the air conditioner 300 .

The diffusers 400 - 1 to 400 - n are devices connected to the ventilator 200 through the ventilation pipe 600 .

The diffuser 400 is mainly installed on the ceiling and performs a function of introducing outdoor air into the room. Unlike the air conditioner 300 , the diffuser 400 does not have an air cleaning function and has a characteristic that the amount of air introduced therein cannot be adjusted.

Among the air volumes supplied by the ventilator 200 , the remaining air amount excluding the air amount supplied to the air conditioners 300 - 1 to 300 -n is supplied to the room through the diffuser 400 .

The cable 500 is configured to connect the air conditioner 300 and the control device 100 , and the control device 100 and the ventilator 200 . The cable 500 may include at least one wired cable port.

The ventilation pipe 600 is connected to the ventilator 200 and is a passage through which outside air is introduced. The air supplied by the ventilator 200 is delivered to the air conditioner 300 through the ventilation pipe 600 .

When the air cleaning and/or ventilation functions of the air conditioner 300 are operated, the more the air conditioners involved in the function, the more the ventilator 200 must supply more air.

In this case, if the air volume of the ventilator 200 is set to the maximum in case the amount of air required for ventilation is not sufficiently supplied, when the ventilation function of the air conditioner 300 is not used at all, a large amount of air is -1 to 400-n), causing excessive ventilation and may also cause noise problems.

In order to solve this problem, the control device 100 needs to identify the amount of air required by the air conditioner 300 . Accordingly, various embodiments in which a constant amount of air to the air conditioner can be supplied to the diffuser 400 regardless of whether the ventilation function of the air conditioner 300 is operated will be described below. .

2 is a block diagram illustrating a configuration of a control device according to an embodiment of the present disclosure.

According to FIG. 2 , the control device 100 includes an interface 110 , a memory 120 , and a processor 130 .

The interface 110 is configured to communicate with the ventilator 200 and the air conditioner 300 . For example, the interface 110 is an AP-based Wi-Fi (Wi-Fi, Wireless LAN network), Bluetooth (Bluetooth), Zigbee (Zigbee), wired / wireless LAN (Local Area Network), WAN (Wide Area Network), Ethernet (Ethernet), IEEE 1394, HDMI (High-Definition Multimedia Interface), USB (Universal Serial Bus), MHL (Mobile High-Definition Link), AES/EBU (Audio Engineering Society/ European Broadcasting Union), Optical, Streaming or downloading from an external device (eg, a source device), an external storage medium (eg, a USB memory), or an external server (eg, a web hard drive) through a communication method such as coaxial A video signal may be input. Here, the image signal may be any one of a standard definition (SD), high definition (HD), full HD, or ultra HD image, but is not limited thereto.

Meanwhile, according to an embodiment, the interface 110 may be implemented as a wired interface, but is not limited thereto.

The memory 120 is a component in which various software or data necessary for the operation of the control device 100 are stored. Although only one memory 120 is illustrated in FIG. 2 , when implemented as an actual product, the memory 120 may be implemented in a form including non-volatile memory such as UVEPROM or EEPROM or volatile memory.

The memory 120 may store information on the total amount of air required for ventilation of the entire indoor space in which the air conditioner 300 and the diffuser 400 are installed. In addition, the memory 120 may also store information about the amount of air that the air conditioner 300 can provide during ventilation.

Here, the information on the total amount of air is information on the maximum value of the amount of air that the ventilator 200 can supply to the room. The information on the total amount of air is set in consideration of the number of air conditioners (300-1 to 300-n) installed indoors when the ventilation system 1000 is installed, the specifications of each air conditioner, and the width of space. can be saved.

For example, if the amount of air required for ventilation of the entire room is 600 liters per hour, the information on the total air amount may be information necessary for the processor 130 to control the ventilator 200 to supply air up to 600 liters per hour. there is.

Information stored in the memory 120 may be stored during manufacturing of the control device 100 or may be downloaded later, or may be updated from time to time from an external source.

The processor 130 controls the overall operation of the control device 100 . Specifically, the processor 130 may be connected to each component of the control device 100 to control the overall operation of the control device 100 . For example, the processor 130 may be connected to the memory 120 and the interface 110 to control the operation of the control device 100 .

According to an embodiment, the processor 130 includes a digital signal processor (DSP), a microprocessor, a central processing unit (CPU), a micro controller unit (MCU), and a micro processing unit (MPU). unit), a controller, an application processor (application processor (AP)), etc. may be named, but in the present specification, it will be referred to as the processor 130. The processor 130 is a SoC (System on Chip), LSI (large scale integration) or may be implemented in the form of a field programmable gate array (FPGA).

When the setting information for the ventilation operation of each air conditioner is received from the at least one air conditioner 300-1 to 300-n, the processor 130 according to an embodiment receives at least one based on the received setting information. It is possible to identify the amount of air required in each of the air conditioners (300-1 ~ 300-n) of.

Subsequently, the processor 130 may adjust the air volume of the ventilator 200 based on the identified air volume and the total air volume obtained from the memory 120 .

Here, the setting information received from the air conditioners 300-1 to 300-n may include information on on/off of the ventilation function.

In this case, the processor 130 may identify the amount of air required by each of the at least one air conditioner based on the received setting information, that is, whether the ventilation function is on/off.

For example, when a specific air conditioner 300-1 is turned on, based on the specification information of the specific air conditioner 300-1, the corresponding air conditioner 300-1 is required to operate a ventilation function. Air volume information can be identified. For example, if the ventilation providing capacity included in the specification information is 100L/h, it can be confirmed that 100 liters of air can be provided per hour.

Here, the at least one air conditioner 300 - 1 to 300 - n may include first and second air conditioners 300 - 1 and 300 - 2 . In this case, the processor 130 receives the first and second setting information for the ventilation operation from each of the first and second air conditioners 300-1 and 300-2, based on the first setting information, 1 The first air amount required by the air conditioner 300 - 1 may be identified. In addition, the processor 130 identifies a second air quantity required by the second air conditioner based on the second setting information, and uses the first air quantity from the sum of the identified first air quantity, the identified second air quantity, and the total air quantity. The air volume of the ventilator 200 may be adjusted based on a calculated value obtained by subtracting the total amount of air that can be provided by the air conditioner and the second air conditioner.

Meanwhile, the processor 130 may adjust the air volume of the ventilator 200 based on the calculated value and the ratio value calculated based on the total amount of air required for ventilation of the entire indoor space.

Specifically, if the calculated ratio value is less than the first threshold value, the processor 130 adjusts the air volume of the ventilator 200 to the first air volume, and the calculated ratio value is greater than or equal to the first threshold value and less than the second threshold value. In this case, the air volume of the ventilator 200 is adjusted to a second air volume stronger than the first air volume, and if the calculated ratio value is equal to or greater than the second threshold value, the air volume of the ventilator 200 is set to a third air volume stronger than the second air volume can be adjusted with A detailed description thereof will be given in FIG. 3 .

According to another example, the setting information for the ventilation operation of each air conditioner 300-1 to 300-n may include information about the on/off setting state of the ventilation operation.

According to another example, the setting information for the ventilation operation of each air conditioner 300-1 to 300-n may include information on whether the damper 310 provided in the air conditioner is closed or opened.

3 is a view for explaining a ventilation required capacity ratio and an air volume control according thereto according to an embodiment of the present disclosure.

The processor 130 according to an embodiment of the present disclosure may control the air volume of the ventilator 200 based on the required ventilation capacity ratio.

Here, the ventilation required capacity ratio means a value calculated through the following formula.

Ventilation required capacity ratio = {(Total air volume required for indoor space ventilation + Air volume required for ventilation of currently ventilated air conditioners - Sum of air volume that can be provided by all installed air conditioners) / (Total air volume required for indoor space ventilation)} * 100%

Here, the total amount of air required for ventilation of the indoor space is the maximum amount of air that the ventilator 200 can supply to the indoor space through the air conditioner 300 and the diffuser 400 .

According to an example, the total amount of air required for indoor space ventilation may be stored in a memory provided in either the control device 100 or the ventilator 200 in the installation stage of the ventilation system 1000 .

The amount of air required for ventilation of air conditioners currently in ventilation operation according to an embodiment of the present disclosure means an amount of air supplied to the indoor space by at least one or more air conditioners 300-1 to 300-n.

The user of the ventilation system 1000 may not only turn on/off the ventilation function of the air conditioner 300 but also set the amount of air flowing in and out through the ventilation function. It is explained on the premise that only On/Off is operated.

When all air conditioners are in Off state, the amount of air required for ventilation operation of air conditioners currently in ventilation operation becomes 0. When all air conditioners are in On state, the amount of air required for ventilation operation of air conditioners in ventilation operation is maximum. do.

The sum of the amount of air that can be provided by all installed air conditioners according to an embodiment of the present disclosure is the total amount of air supplied to the room when at least one or more air conditioners 300 - 1 to 300n are all in the ventilation operation.

For example, when a total of three air conditioners are each supplying 100L of air per hour to an indoor space, the total amount of air that can be provided by all installed air conditioners is 300L/h.

As a result, the ventilation required capacity ratio according to an embodiment of the present disclosure increases as the proportion of air conditioners operating with the ventilation function increases. do.

According to FIG. 3 , the first threshold value for the ventilation required capacity ratio is 33%, and the second threshold value is 66%. When the calculated ventilation demand capacity ratio is less than 33%, the processor 130 controls the ventilator 200 to operate as a breeze.

On the other hand, when the calculated ventilation demand capacity ratio is 33% or more and less than 66%, the processor 130 controls the ventilator 200 to operate with a weak wind.

In addition, when the calculated ventilation required capacity ratio is 66% or more, the processor 130 controls the ventilator 200 to operate in strong wind.

For example, in the ventilation system including the first and second air conditioners 300 - 1 and 300 - 2 , the total amount of air required to ventilate the indoor space is 300 liters per hour, the first air conditioner 300 - 1 If the amount of air that can be provided is 120 liters per hour and the amount of air that the second air conditioner 300-2 can provide is 90 liters per hour, when all the air conditioners perform ventilation operation, the required ventilation capacity ratio becomes 100%. . In this case, the air volume of the ventilator 200 becomes a strong wind.

According to FIG. 3 , when only the first air conditioner 300 - 1 is ventilating, the required ventilation capacity ratio is (300+120-210) / (300) = 70%. In this case, the processor 130 adjusts the air volume of the ventilator 200 to a strong wind.

On the other hand, when only the second air conditioner 300 - 2 is performing the ventilation operation, the ventilation required capacity ratio becomes (300+90-210) / 300 = 60%. In this case, the processor 130 adjusts the air volume of the ventilator 200 to a weak wind.

In addition, when all air conditioners are operating with the air cleaning function, the required ventilation capacity ratio becomes (300+0-210) / 300 = 30%. In this case, the processor 130 adjusts the air volume of the ventilator 200 to a breeze.

Although the control of the air volume of the ventilator 200 in consideration of the required ventilation capacity ratio according to an embodiment of the present disclosure has been described according to an arbitrarily set critical range, it is not limited thereto, and the manufacturer and the system installer may freely choose the critical range of the required ventilation capacity ratio. can be set differently.

4 is a view for explaining the control of the air volume according to the ratio of the air conditioner in the ventilation operation according to an embodiment of the present disclosure.

In FIG. 3 , the air volume control of the ventilator 200 based on the required ventilation capacity ratio has been described, but according to an embodiment of the present disclosure, based on the ratio of the air conditioner 300 with the ventilation function turned on, It is also possible to adjust the air volume of the ventilator 200 .

For example, assuming that a total of four air conditioners (300-1, 300-2, 300-3, 300-4) are installed in an indoor space, if there is less than one air conditioner in the ventilation operation, the processor ( 130) adjusts the air volume of the ventilator 200 to a breeze.

On the other hand, when there are two air conditioners in the ventilation operation, the processor 130 adjusts the air volume of the ventilator 200 to a weak air.

In addition, when three or more air conditioners are ventilating, the processor 130 adjusts the air volume of the ventilator 200 to a strong wind.

The control of the air volume of the ventilator 200 according to an embodiment of the present disclosure is not limited to the critical range described in FIG. 4 , and manufacturers and system installers may set the critical range of the required ventilation capacity ratio differently.

5 is a view for explaining the control of the air volume according to the ratio of the air conditioner in which the damper is opened according to an embodiment of the present disclosure.

According to an example, the damper 310 is opened only when the air conditioner 300 performs a ventilation operation. In this case, the processor 130 may identify whether each air conditioner 300 performs a ventilation operation based on whether the damper 310 is open.

For example, when a total of four air conditioners (300-1, 300-2, 300-3, 300-4) are installed in an indoor space, when there is less than one air conditioner with the damper 310 open , the processor 130 may adjust the air volume of the ventilator 200 to be a breeze.

Meanwhile, when there are two air conditioners with the damper 310 open, the processor 130 may adjust the air volume of the ventilator 200 to a weak wind.

In addition, when there are three or more air conditioners with the damper 310 open, the processor 130 may adjust the air volume of the ventilator 200 to a strong wind.

Here, the gentle wind, the weak wind, and the strong wind are given as examples indicating the strength of the wind volume, and it goes without saying that terms indicating the strength of the air volume may be different depending on the manufacturer of the ventilator 200 .

The control of the air volume of the ventilator 200 according to an embodiment of the present disclosure is not limited to the critical range described in FIG. 5 , and manufacturers and system installers may set the critical range of the required ventilation capacity ratio differently.

6 is a view for explaining the control of the air volume according to the characteristics of each indoor space according to an embodiment of the present disclosure.

According to an example, in the indoor space 600, a total of four air conditioners 300-1, 300-2, 300-3, 300-4 and a total of seven diffusers 400-1, 400-2, 400-3 , 400-4, 400-5, 400-6, 400-7) are installed. For example, an air conditioner is installed in some spaces (611, 612, 613, 614) of the plurality of spaces (to), and a diffuser is installed in some spaces (611, 612, 623, 624, 613, 614, 627). can be installed.

When the total air volume required for ventilation of the entire indoor space 600 is set to 600 L/h, as described with reference to FIG. 3 , the processor 130 may adjust the air volume of the ventilator 200 based on the required ventilation capacity ratio.

In an embodiment of the present disclosure, it is assumed that the air volume of the ventilator 200 described with reference to FIGS. 3 to 5 is 600 L/h for a strong wind, 400 L/h for a weak wind, and 200 L/h for a breeze.

According to an embodiment, when the ventilation function is operated in the air conditioners 300-1, 300-2, and 300-3 provided in the partial spaces 611, 612, and 613, the required ventilation capacity ratio is 75%. . In this case, since the processor 130 sets the air volume of the ventilator 200 to a strong wind, the air conditioners 300-1, 300-2, and 300-3 among the 600L/h air volume provided by the ventilator 200 200L/h excluding 400L/h supplied to each diffuser is evenly distributed and supplied.

According to another embodiment, when the ventilation function is operated in the air conditioners 300 - 1 and 300 - 4 provided in the partial spaces 611 and 614 , the required ventilation capacity ratio is 53.3%. In this case, since the processor 130 sets the air volume of the ventilator 200 to a weak wind, 270L supplied to the air conditioners 300-1 and 300-4 among the 400L/h air volume provided by the ventilator 200 130L/h excluding /h is evenly distributed and supplied to each diffuser.

According to another embodiment, when the ventilation function is operated in the air conditioner 300 - 2 provided in the partial space 612 , the required ventilation capacity ratio is 25%. In this case, since the processor 130 sets the air volume of the ventilator 200 to a breeze, 100 L/h supplied to the air conditioner 300 - 2 is excluded from the 200 L/h air volume provided by the ventilator 200 . 100L/h is evenly distributed and supplied to each diffuser.

According to various embodiments of the present disclosure, by controlling the air volume of the ventilator 200, the fluctuation range of the air supply amount supplied to the diffuser can be adjusted not to be large, so that noise can be prevented while providing an appropriate ventilation function.

7 is a flowchart illustrating a control method according to an embodiment of the present disclosure.

The display control method according to an embodiment of the present disclosure identifies the total amount of air required for ventilation of the entire indoor space in which at least one diffuser and at least one air conditioner are installed (S710).

Subsequently, setting information for a ventilation operation of each air conditioner is received from at least one air conditioner ( S720 ).

Then, the amount of air required by each of the at least one air conditioner is identified based on the setting information ( S730 ).

Finally, the air volume of the ventilator is adjusted based on the total air amount and the identified air amount (S740).

Here, the at least one air conditioner may include first and second air conditioners.
