For example, the air conditioner system 10 may use a temperature sensor and a humidity sensor provided in the air conditioner 110 . For example, the ventilation device 130 may be driven using sensing data of a temperature sensor and a humidity sensor included in the air conditioner 110 . In addition, the air conditioner system 10 may combine sensing data of sensors provided in each device to manage data for each location or to improve the accuracy of sensing data.

Also, the sensor 150 may include a sensor disposed outdoors. For example, it may correspond to a temperature sensor and a dust sensor disposed outdoors.

Alternatively, the air conditioner system 10 may receive and use data sensed by the external sensor 20 . At least one device in the air conditioner system 10 may receive sensing data directly from the external sensor 20 or may receive it through the server 30 .

On the other hand, devices included in the air conditioner system 10 such as the air conditioner 110 , the air purifier 120 , and the ventilation device 130 are provided with a communication module to communicate with other devices and the server 30 or network. can connect to

Meanwhile, the communication module included in the devices included in the air conditioner system 10 may be a Wi-Fi communication module, and the present invention is not limited to the communication method.

A user may operate devices included in the air conditioner system 10 by using the controller 140 . According to an embodiment, the controller 140 may include a display to provide information on at least one of the devices included in the air conditioner system 10 as visual information.

The controller 140 may be an integrated controller capable of overall controlling the devices included in the air conditioner system 10 or a controller for a specific device. For example, the controller 140 may be a thermostat for controlling the temperature of an indoor space, or a thermostat for controlling the air conditioner 110 . Even when the controller 140 is a controller for a specific device, when the specific device is a device having a high priority, other devices may be controlled directly or through the specific device.

Meanwhile, according to an embodiment, the controller 140 may be a controller of any one of the devices included in the air conditioner system 10 . In this case, the controller 140 may be a controller of a device serving as a master in the air conditioner system 10 .

The air conditioner system 10 according to an embodiment of the present invention may control a plurality of devices by interworking based on sensing data of the sensor 150 .

As interest in air quality increases, the use of the air purifier 120 is increasing. On the other hand, as the use of the air purifier 120 increases, concerns about the increase in energy consumption and the management of carbon dioxide that cannot be managed by the air purifier 120 are also increasing.

Therefore, the air conditioner system 10 according to an embodiment of the present invention provides integrated air quality management by using ventilation and air cleaning together through product interlocking, and has high energy efficiency by comparing indoor and outdoor air quality. A smart air conditioning control service can be provided. In addition, it is possible to prevent inefficient heating and cooling during ventilation and air cleaning.

In the past, it was a one-dimensional management that turned on/off individual air conditioning products, and the problem for energy efficiency could only be solved by using less products. In addition, there was a inconvenience in that the user had to turn on the product sequentially by considering the energy efficiency problem. For example, when the CO2 level and temperature rose, the user ventilated and then operated the air conditioner to cool.

However, in the air conditioner system 10 according to an embodiment of the present invention, various management factors such as indoor temperature, humidity, fine dust concentration, and CO2 level are controlled by the air conditioner 110 , the air purifier 120 , and the ventilation device. (130) can be optimized.

In addition, the most efficient operation method can be automatically selected through the energy simulation function. The air conditioner system 10 according to an embodiment of the present invention may automatically calculate and apply which combinations of products are effective to use for current air conditioning management through an energy simulator.

The air conditioner system 10 according to an embodiment of the present invention enables faster and more systematic air conditioning control by selecting the time and equipment required to achieve a target air conditioning condition.

In addition, the air conditioner system 10 according to an embodiment of the present invention receives data from the database through the external sensor 20 and the cloud 30, compares it with indoor information, and bets whether ventilation is good or not. You can judge if the circulation is good.

When managing indoor air conditioning, it is often operated based on the air quality and temperature and humidity of the current indoor space. However, if outdoor air quality, temperature and humidity are used appropriately, it is possible to create a suitable air conditioning environment with less use of home electronic devices. Accordingly, the air conditioner system 10 according to an embodiment of the present invention may acquire outdoor data and use it for air conditioning control.

Meanwhile, such interlocking control, optimization, and energy use simulation may be performed by the controller 140 or any one device serving as a master. Alternatively, the air conditioner system 10 may operate according to a control signal received from the server 30 that has performed interlocking control, optimization, and energy use simulation.

2 is a flowchart illustrating a control method of an air conditioner system according to an embodiment of the present invention.

The air conditioner system 10 according to an embodiment of the present invention may acquire indoor air quality data through one or more sensors 150 ( S210 ). Here, the betting air quality data may include indoor carbon dioxide concentration, fine dust concentration, and the like.

The air conditioner system 10 may acquire outdoor air temperature data and outdoor air quality data from an external device ( S220 ). The air conditioner system 10 may acquire outdoor air temperature data and outdoor air quality data from an external sensor 20 such as a temperature sensor, a fine dust sensor, and a carbon dioxide sensor. Alternatively, the air conditioner system 10 may acquire outdoor air temperature data and outdoor air quality data from the server 30 . Here, the outdoor air quality data may include outdoor carbon dioxide concentration, fine dust concentration, and the like. The outdoor air quality data may be outdoor air quality data of an area closest to the indoor.

The air conditioner system 10 may determine an optimal control mode based on indoor/outdoor data (S230) and operate according to the control mode determined as the optimal control mode (S240).

The air conditioner system 10 includes a plurality of sets in which at least one of a type, an operation sequence, and an operation mode of an operating device is differently set based on a set temperature, the outside air temperature, the bet air quality, and the outside air quality. Any one of the control modes may determine the optimal control mode.

For example, based on indoor/outdoor data, the air conditioner 110 and the air purifier 120 may operate simultaneously. Alternatively, the ventilation device 130 may operate alone or two or more devices may operate sequentially according to indoor/outdoor data.

Meanwhile, according to an embodiment of the present invention, energy usage together with indoor/outdoor data may be used as a key condition to determine a control mode. Among the combinations that can achieve the target air conditioning conditions, the combination with the lowest energy consumption can be selected as the optimal control mode.

The air conditioner system 10 determines candidate modes having different combinations of operating devices based on the set temperature, the outdoor air temperature, the indoor air quality, and the outdoor air quality, and calculates the energy consumption of the determined candidate modes Accordingly, a candidate mode having the smallest energy consumption may be selected as the optimal control mode. For example, based on indoor/outdoor data, when it is necessary to lower the indoor temperature and carbon dioxide, it may be determined that the air conditioner and the ventilator are operated simultaneously or sequentially as a candidate mode. In addition, when the outdoor temperature is lower than the indoor temperature, the independent operation of the ventilation device 130 may also be determined as a candidate mode. The air conditioner system 10 may select ( S230 ) and operate ( S240 ) to operate the ventilation device 130 independently as the optimal control mode by simulating the energy consumption of the candidate modes.

The air conditioner system 10 according to an embodiment of the present invention may determine the optimal control mode based on the set temperature, the outdoor temperature, the indoor air quality, the outdoor air quality, and the energy consumption. In this case, while determining whether to operate the air conditioner based on the set temperature and the outside temperature, maintaining the setting of the air conditioner operation, operating other devices, and changing the setting of the air conditioner operation The optimal control mode may be determined by a combination of low energy consumption among operating other devices.

On the other hand, in the air conditioner system 10, when the difference between the set temperature and the outdoor air temperature is smaller than a preset reference value and the outdoor air quality satisfies the air quality standard, the ventilation device 130 introduces the outdoor air into the room. A first mode may be selected as the optimal control mode.

If the outdoor air quality is good enough to satisfy the air quality standards, it may be better to operate the ventilation device 130 than to operate the air purifier 120 . Here, the air quality standard may be set according to each country's air quality standard or set by a manufacturer or a user.

On the other hand, if the difference between the set temperature and the outside temperature is smaller than a preset reference value, it is not necessary to operate the air conditioner 110 for indoor temperature management even when the ventilation device 130 is operated. In addition, if the difference between the set temperature and the outside air temperature is smaller than a preset reference value, the set temperature may be reached with only outside air, so that there is no need to operate the air conditioner 110 . Accordingly, when the difference between the set temperature and the outside air temperature is smaller than a preset reference value and the outside air quality satisfies the air quality standard, the ventilator 130 may operate alone to introduce outside air into the room.

On the other hand, the air conditioner system 10, when the difference between the set temperature and the outside air temperature is smaller than a preset reference value and the outdoor air quality does not satisfy the air quality standard, the air purifier 120 operates in the second mode. The optimum control mode may be selected. If the air quality standards are not satisfied due to poor external air quality, the air purifier 120 may operate to purify indoor air. In some cases, when the air purifier 120 operates, the ventilation device 130 operates in a mode for circulating indoor air, so that air purification can be performed faster.

Meanwhile, when the difference between the set temperature and the outside air temperature is greater than a preset reference value, the air conditioner system 10 may select the third mode in which the air conditioner 110 operates as the optimal control mode. When the difference between the set temperature and the outside air temperature is greater than a preset reference value, it is not easy to adjust the indoor temperature to the set temperature using outside air. In addition, if the difference between the set temperature and the outdoor temperature is large, the temperature control of the indoor space is prioritized, so that the air conditioner 110 may operate. Even in this case, since the ventilation device 130 operates in a mode for circulating indoor air, temperature control for the entire space can be performed more quickly.

Meanwhile, when the difference between the set temperature and the outside air temperature is greater than a preset reference value, the air conditioner system 10 sets the fourth mode in which the air purifier 120 and the air conditioner 110 operate to the optimal control mode. can be selected as

When the difference between the set temperature and the outside temperature is greater than a preset reference value, the air conditioner 110 may operate for temperature management. In addition, the air purifier 120 may be driven together with the air conditioner 110 to simultaneously perform air cleaning. Here, the operation of the air purifier 120 may be determined according to the indoor air quality data obtained by the sensor 150 , for example, the concentration of fine dust. If the indoor fine dust concentration satisfies the air quality standard, the air purifier 120 may not operate.

According to an embodiment of the present invention, the air conditioner system 10 may detect the user's location through the sensor 150 or a camera provided in any one device. As a result of detecting the user's location, when the user stays in a specific space for a predetermined time or longer, air is circulated in another space connected by a duct to the specific space without operating the air conditioner 110 and the air purifier 120 . , it is possible to reduce the increase in carbon dioxide by a person staying in a predetermined space for a long time.

For example, when the user sleeps in the bedroom at night, the air conditioner system 10 may prioritize the bedroom and start the air conditioning mode. In addition, the TV, lighting, and air conditioning equipment in the living room can be turned off.

An optimization algorithm may be applied to the air conditioning mode of the bedroom. For example, when the indoor CO2 concentration sensed through the sensor 150 increases while the user sleeps, the ventilator 130 may start introducing outdoor air.

In addition, when the indoor CO2 concentration sensed through the sensor 150 decreases and the outdoor fine dust concentration gradually increases through the outdoor sensor, the ventilation device 130 may be switched to the betting circulation mode. At this time, the air purifier 120 may operate or the air conditioner 110 may operate in the air purifying mode.

The air conditioner system 10 according to an embodiment of the present invention can more accurately calculate the air conditioning control mode by comparing the outdoor air condition with the indoor air condition. By comparing indoor and outdoor air quality, it is possible to combine and operate air conditioning equipment by selecting and judging outdoor ventilation, internal circulation, and air purification.

In addition, according to an embodiment of the present invention, it is possible to comprehensively manage problems that cannot be solved with only a specific device (eg, high CO2 level and temperature), and comprehensive indoor air conditioning environment management including energy and temperature as well as air quality .

The air conditioner system 10 according to an embodiment of the present invention provides a graph for energy efficiency and a predicted value of energy consumption of various air conditioning devices through the display of the controller 140, the mobile terminal, and individual devices. A user interface (UI) that compares air conditioning equipment, a mode that operates more efficiently through a combination of several air conditioning equipment, a user interface (UI) that compares the energy consumed when operating in combination with individual energy consumption of several air conditioning equipment, indoor and outdoor air quality A user interface (UI) for comparison may be provided.

Also, the user interface screen may include information 320 corresponding to a selected item among the menu items 310 . Alternatively, the user interface screen may include information on items having a change of a certain level or more.

Meanwhile, the user interface screen may include information on the operation mode of the current air conditioner system 10 .

When the indoor CO2 level rises, carbon dioxide is expelled outdoors and oxygen is supplied. Referring to FIG. 3 , the CO2 level of the space where the user stays is measured, the mode is automatically changed to the inflow of external air, and the ventilation mode 330 is notified.

In the ventilation mode, the ventilation device 130 may perform natural ventilation according to indoor and outdoor temperatures. Alternatively, in the ventilation mode, the ventilation device 130 may provide ventilation without temperature change through insulation ventilation (ERV) according to indoor and outdoor temperatures. Meanwhile, in the ventilation mode, it is possible to operate the air purifier 120 together with the ventilation device 130 or to perform ventilation through a filter according to the external air quality.

Referring to FIG. 4 , the betting circulation mode 410 may be displayed on the display 141 . When the user stays in one space for a long time, such as during sleep, more efficient air conditioning management is possible by mixing the air in the bedroom and other indoor spaces (eg, living room) in the air sharing mode 410 instead of ventilating the outside air.

Referring to FIG. 5 , a user interface screen for managing temperature and air cleanliness by comparing 510 indoor air and outdoor air quality may be displayed on the display 141 . In addition, when the outdoor air quality is bad, it is possible to manage the air quality in the bet circulation mode 520 TEk.

6 and 7 are diagrams referenced in the description of the operation of the air conditioner system according to an embodiment of the present invention.

Referring to FIG. 6 , the air conditioner system 10 selects an optimal control mode from among a plurality of control modes 630 by applying an energy usage and an optimal control algorithm based on indoor and outdoor data 610 , can be controlled

A plurality of modes 630, for example, outside introduction mode 631, internal circulation and air cleaning mode 632, air conditioning execution and internal circulation mode 633, air conditioning execution and air cleaning mode 634, etc. various Modes by combination can be prepared.

In addition, the air conditioner system 10 operates the devices based on the difference 611 between the set temperature and the outdoor temperature, the difference 612 between the indoor fine dust concentration and the outdoor fine dust concentration, and the indoor carbon dioxide concentration 613 . can do it

For example, when the difference between the set temperature and the outside air temperature is ±2 degrees or less and the outdoor air fine dust PM.2.5 concentration is less than 50 μg/m3, the air conditioner system 10 enters the outside air introduction mode 631. The ventilation device 130 may be operated.

In addition, the air conditioner system 10, when the difference between the set temperature and the outside air temperature is ± 2 degrees or less and the outdoor fine dust PM.2.5 concentration is greater than 50 μg/m3, the internal circulation and air cleaning mode 632 , the air purifier 120 or the air conditioner 110 may be operated in the air cleaning mode. In addition, in the case of the ventilation device 130 capable of circulating the bet, the ventilation device 130 operates in the bet circulation mode and the ventilation device 130 otherwise may be turned off in the bet circulation mode.

The air conditioner system 10 may operate the air conditioner 110 when the difference between the set temperature and the outside temperature is greater than ±2 degrees (633, 634). At this time, in consideration of the energy consumption according to the current air quality and temperature, it may operate in the air conditioning execution and internal circulation mode 633 or the air conditioning execution and air cleaning mode 634 .

On the other hand, in the air conditioner system 10 according to an embodiment of the present invention, the difference between the set temperature and the indoor temperature is greater than the difference between the set temperature and the outdoor temperature. If the CO2 level is high, consider as a candidate to perform ventilation and use more energy from the air conditioner 110 to maintain the inside temperature, or to block ventilation and operate the oxygen (O2) generator 160 to reduce the loss of temperature difference. can The air conditioner system 10 may select a control logic with a low energy loss from among the candidates after simulating the energy usage.

In the air conditioner system 10 according to an embodiment of the present invention, when the indoor fine dust concentration deteriorates while the air conditioner 110 is in operation, the air conditioner 110 generates more energy while performing ventilation. A combination of maintaining the indoor temperature by using and a combination of running the air purifier 120 while maintaining the operation of the air conditioner 110 may be considered as candidates. The air conditioner system 10 may select a control logic with less energy loss from among candidates after simulating the energy usage.

The air conditioner system 10 according to an embodiment of the present invention can predict the energy used by several devices, determine which combination of products is most effective to use, and provide a user interface screen for this. can

Referring to FIG. 7 , when the set temperature is 30 degrees, the set air quality is 'good', the outdoor temperature is 30 degrees, the air quality is 'bad', and the indoor temperature is 35 degrees , the air quality is 'bad'.

In this case, energy consumption of an air conditioner (A/C), a ventilator, and an air purifier may be presented by quantifying the energy for each device in order to satisfy desired settings.

In addition, the air conditioner system 10 may adopt the most efficient method by comparing the total energy values required to achieve the target. For example, in order to lower the temperature and clean the air, it is possible to select whether the ventilation is better by looking at the current outdoor temperature and air cleanliness, or whether the air conditioner 110 and the air purifier 120 are operated using the air in the room.

Since the set temperature is lower than the indoor temperature and the outdoor temperature is the same as the set temperature, the set temperature may be reached through cooling operation or outside air inflow. In addition, both indoor and outdoor air quality is poor, so air purification is essential in relation to air quality.

In the example of FIG. 7 , the energy consumption when operating the ventilator 130 and the air purifier 120 is smaller than the energy consumption when operating the air conditioner 110 and the air purifier 120 . and to operate the air purifier 120 .

Accordingly, it is possible to automatically and efficiently manage the air conditioning without the user's involvement, and it is possible to reduce energy use.
