Description

The present invention relates to an air conditioning control device, an air conditioner, an air conditioning system, an air conditioning control method and a program.

If there is an opening in the air-conditioned room, the efficiency of air-conditioning will decrease if air flows in and out of the room. On the other hand, depending on the indoor and outdoor temperatures, the efficiency of air conditioning may be increased by operating the air conditioner and the ventilation fan arranged at the opening of the room at the same time. For example, in Patent Document 1, when the room temperature does not reach the set temperature while the air conditioner is operating, if the outside air temperature is closer to the set temperature than the room temperature, the ventilation fan is operated to use the heat of the outside air for air conditioning. The operation method of the aircraft is shown.

Japanese Unexamined Patent Publication No. 2-178556

In the operation method of the air conditioner proposed in Patent Document 1, the air conditioner and the ventilation fan are operated when the set temperature and the indoor and outdoor temperatures satisfy certain conditions. However, with such a simple method, depending on the wind direction of the temperature-controlled air generated by the air conditioner, the temperature-controlled air may be discharged as it is by the ventilation fan, and the efficiency of air conditioning may rather decrease. Therefore, in the operation method of the air conditioner described in Patent Document 1, the air conditioning efficiency may be lowered.

The present invention has been made in view of the above reasons, and an object of the present invention is to provide an air conditioning control device, an air conditioner, an air conditioning system, an air conditioning control method, and a program capable of performing highly efficient air conditioning.

In order to achieve the above object, the air control device according to the present invention includes an opening information acquisition unit and an air conditioner control unit. The opening information acquisition unit acquires position information indicating the position of the opening where air inflow and outflow occurs between the air conditioning target area by the air conditioner and the outside, and state information indicating the state of the opening. The air conditioner control unit controls the air conditioner based on the position information and the state information acquired by the opening information acquisition unit. The state information includes information indicating that the opening is in an exhaust state in which exhaust from the air-conditioned area to the outside is being carried out. The air conditioner control unit controls the air conditioner based on the state information so as not to blow the wind to the opening in the exhaust state.

According to the present invention, the air conditioner is controlled according to the position and state of the opening. Therefore, it is possible to prevent a decrease in air conditioning efficiency due to the inflow and outflow of air from the opening, and it is possible to efficiently perform air conditioning.

Hereinafter, the air conditioning control device according to the embodiment of the present invention, the air conditioning system incorporating the air conditioning control device, and the air conditioning control method executed by the air conditioning system will be described.

(Embodiment 1)
FIG. 1 shows the configuration of the air conditioning system 11 according to the first embodiment. As shown in the figure, the air conditioning system 11 according to the embodiment is installed in a house 21 that defines an air conditioning target space, and is connected to an air conditioning control device 110 that controls the whole and an air conditioning control device 110 via a network NW. The air conditioner 100, the ventilation fan 200, and the opening detector 300 are provided.

The air conditioner (hereinafter, simply referred to as an air conditioner) 100 performs air conditioning for cooling and heating by blowing out air whose temperature has been adjusted by controlling the blowing direction of up, down, left and right into the room.

The ventilation fan 200 is arranged on a ventilation hole (not shown) which is an opening formed in the house 21, and the indoor air is discharged to the outside through the opening, and the outside air is discharged to the air-conditioned space. It is also possible to supply air to the room and close the shutter to close the opening. Further, the ventilation fan 200 transmits a signal indicating its operating state to the air conditioning control device 110. The signal indicating the operating state indicates a closed state, an air supply state, an exhaust state, an intensity, and the like.

The air conditioning control device 110 is connected to the air conditioner 100 and the air conditioner 100 and the ventilation fan 200 installed in the same space by a network. The air conditioning control device 110 receives a signal of the operating state of the ventilation fan 200. Further, the air conditioning control device 110 transmits a signal for performing blow control to the air conditioner 100. The air conditioner 100 receives a signal from the air conditioning control device 110 and performs ventilation control.

Although there is only one ventilation fan 200 in the figure, there may be a plurality of ventilation fans 200 in the same space, and in that case, the air conditioning control device 110 individually transmits the operating state to the air conditioning control device 110.

The opening detector 300 is arranged indoors, acquires the positions and states of the ventilation fan 200 and other openings, and transmits the positions and states to the air conditioning control device 110. Here, the opening refers to a place where an inflow or outflow of an air flow occurs in a space to be air-conditioned and a space outside the space. Specifically, it refers to ventilation fans, windows, and doorways.

The opening detector 300 includes, for example, an infrared sensor that detects heat. In this case, the infrared sensor scans the room and senses the temperature condition in the room to confirm the position and state of the opening. As a method of confirming the position, if the windows and doorways are open, it is possible to detect because a temperature difference with the surroundings occurs during air conditioning by the air conditioner 100. As another method, when installing the air conditioner 100, a small transmitter capable of generating heat at a constant temperature is attached to the opening including the ventilation fan 200, and the transmitter is detected by an infrared sensor. It is possible to detect the position of the opening. Since it is considered that the position of the opening does not change, it is usually sufficient to perform the process of detecting the position of the opening only once when the air conditioner 100 is installed. When the air conditioner 100 includes an infrared sensor for detecting a human body, it is possible to use the sensor for detecting the human body instead of installing the infrared sensor separately. In addition, when a transmitter is installed and the position of the opening is detected by a sensor, the position of the transmitter is not limited to the detection of heat by an infrared sensor, for example, the transmitter that emits light is detected by an optical sensor. If can be detected by the sensor, the method does not matter.

As another configuration of the opening detector 300, for example, a remote controller (hereinafter referred to as a remote controller) provided with a liquid crystal display panel and input means such as a button or a touch panel can be used. For example, a liquid crystal display panel displays a top view of the room. When the air conditioner 100 is installed, the position of the air conditioner 100 and the position of the opening of the ventilation fan 200 or the like are input by the input means of the remote controller. Since it is considered that the position of the opening is basically unchanged, it is usually sufficient to carry out the procedure only once when the air conditioner 100 is installed. As this remote controller, a remote controller for controlling the air conditioner 100 or the ventilation fan 200 may be used instead of providing a dedicated remote controller. Further, it may be possible to use an in-house controller for controlling an air conditioner 100, a ventilation fan 200, or a device installed in a house 21 such as a television or a refrigerator.

FIG. 2 is a block diagram showing a configuration example of the air conditioning control device 110.
As shown in the figure, the air conditioning control device 110 obtains opening information from a ventilation control unit 400 that creates a control signal for ventilation control and transmits it to the air conditioner 100, a ventilation fan 200, and an opening detector 300. A control signal is transmitted from the unit information acquisition unit 500, the opening information storage unit 510 that stores the opening information, and the ventilation control unit 400 to the air conditioner 100, and the opening information is transmitted from the ventilation fan 200 and the opening detector 300. A communication unit 700 for receiving is provided.

The blow control unit 400 includes a wind direction control unit 410 that controls the wind direction of the air blown by the air conditioner 100, and an air volume control unit 420 that controls the air volume of the air blown by the air conditioner 100. The control signal generated by the wind direction control unit 410 and the air volume control unit 420 is transmitted to the air conditioner 100 to perform blow control. The wind direction control unit 410 reads the opening information from the opening information storage unit 510 and controls the wind direction according to the position and state of the opening.

An example of the method of detecting the opening position by the opening detector 300 will be described with reference to FIG. FIG. 3 is a top view of a room in which the air conditioner 100 is installed, and shows the positions of the air conditioner 100 and the openings existing in the room. Reference numeral 210 indicates a window that can be opened and closed arbitrarily, and reference numeral 220 indicates a door that allows people to enter and exit. In the case of this example, the room, which is the target space for air conditioning, has a ventilation fan 200, a window 210, and a door 220 as openings. The air conditioner 100 is installed above the center of one side having a wall in the left-right direction.

Here, it is assumed that the infrared sensor 310 and the remote controller 320 are installed indoors as the opening detector 300, and the infrared sensor 310 is attached to the vicinity of the center of the left and right portions of the air conditioner 100 and the lower front portion. Further, it is assumed that the remote controller 320 is provided with a liquid crystal panel and operation keys, and is installed on a wall in the room. The area on the front side of the air conditioner in the room is divided so that the angles from the left and right centers of the air conditioner 100 are even. FIG. 4 shows the divided areas. Reference numeral 600 is an air-conditioning area, which is an area in which the indoor space is divided, and the number is 10 from 600a to 600j. The number of areas is not limited to this number. By dividing the area into smaller pieces, it is possible to detect the position of the opening with higher accuracy. In FIG. 4, the area is divided only to the left and right, but it is also possible to divide the area into upper and lower parts. If the air conditioner is installed on either the left or right wall instead of the center of the room, or if the room is large, the number of air conditioning areas 600 and the individual size are appropriate compared to the size of the indoor space. It is desirable to be able to set the division of the area so that it becomes.

The infrared sensor 310 detects where the opening exists in the air-conditioned area from 600a to 600j. The procedure is to install a small transmitter capable of generating heat at a constant temperature in all openings. It is desirable to mount the transmitter at a position that can be detected by the infrared sensor 310 and as close to the horizontal center of the opening as possible. Then, the infrared sensor 310 scans the room to detect in which air-conditioned area 600 the heat-generating transmitter is located. It is assumed that the infrared sensor 310 scans from left to right when viewed from the air conditioner 100. As a result, it is detected that the ventilation fan 200 is an opening existing in the air-conditioned area 600c and the window 210 is an opening existing in the air-conditioned area 600g. Openings may exist across areas. The door 220 exists across the air-conditioned areas 600i and 600j. In such cases, the transmitter will be detected near the boundaries of the area. If the transmitter is detected within a certain range from the boundary of the area, it is detected as an opening that straddles two air-conditioned areas adjacent to the boundary. Therefore, the door 220 is detected as an opening straddling the air conditioning areas 600i and 600j. In the example of FIG. 4, it is assumed that the size of the opening is small enough to fit in the divided air-conditioned area, but if the upper, lower, left, and right divisions of the air-conditioned area are fine, it is determined whether the detected location is near the boundary. Regardless of the above, it is detected as if it straddles a plurality of areas up, down, left, and right centering on the detected air conditioning area. When the size of the opening is larger than a certain size, a number of transmitters proportional to the size of the opening are installed at regular intervals to perform detection, and detection is performed as a plurality of adjacent openings.

FIG. 5 is an example of the data of the detected opening position information. It is composed of an opening number which is a number for specifying an opening and an air-conditioned area where the opening is present. Here, the air-conditioned area 600c corresponds to the air-conditioned area C, 600 g corresponds to the air-conditioned area G, 600i corresponds to the air-conditioned area I, and 600j corresponds to the air-conditioned area J. The opening is detected from left to right when viewed from the air conditioner 100, and the ventilation fan 200 corresponds to the opening No1, the window 210 corresponds to the opening No2, and the door 220 corresponds to No3.

The method of detecting the opening position can also be manually input using the remote controller 320. For example, the remote controller 320 may display the top view of the room and manually input the position of the opening in the top view.

The method for detecting the opening position may not be the method described here as long as it can determine in which direction the opening exists with respect to the air conditioner 100.

Since it is considered that the position of the opening existing in the room basically does not change, it may be performed only once when the air conditioner 100 is installed. After that, if the position or number of openings changes, the position of the openings is detected each time.

When the detected opening is the ventilation fan 200, it is also possible to associate the detected opening with the ventilation fan 200 connected to the network. The mapping is performed manually using the remote controller 320.

The opening detector 300 also detects the opening state of the opening whose position has been detected. There are five types of openings: air supply, exhaust, air supply / exhaust, open, and closed. The air supply state is a state of an opening that generates an air flow that flows into the room from the outside, and corresponds to, for example, a ventilation fan that is performing an air supply operation. The exhaust state is a state of an opening that generates an air flow flowing out from the room to the outside, and corresponds to, for example, a ventilation fan performing an exhaust operation. The air supply / exhaust state is a state of an opening in which air supply and exhaust are performed at the same time, and corresponds to, for example, a ventilation fan performing air supply / exhaust operation. The open state is a state of an opening in which neither air supply nor exhaust is performed, and corresponds to, for example, an entrance / exit such as an open window or door. The closed state is a state in which the opening is closed, and corresponds to, for example, a ventilation fan during operation stoppage, a closed window, or a door.

The method for detecting the opening state is, for example, as follows. In the case of the ventilation fan 200 whose opening is connected to the network NW, the state can be detected by receiving the operation signal transmitted from the ventilation fan 200 by the opening detector 300. From the operation signal of the ventilation fan 200, it is possible to detect whether the ventilation fan 200 is in the air supply operation state, the exhaust operation state, the air supply / exhaust operation state, or the stopped state, and the state of the corresponding opening according to the operation state is the air supply state. , Exhaust state, supply / exhaust state, closed state can be detected.

The state detection when the opening is a ventilation fan is not limited to this method as long as it can detect whether or not the ventilation fan is in an operating state and what the operating state is. For example, if the ventilation fan only supports exhaust operation, by monitoring the operating power of the ventilation fan to check the operating state or the stopped state, if the ventilation fan is in the operating state, it is in the exhaust state, and if it is in the stopped state, it is in the closed state. It is also possible to detect as. In addition, for example, in the case of a ventilation fan that manually switches the operation, the opening detector 300 detects the state of the opening of the ventilation fan by manually inputting the state of the ventilation fan to the remote controller 320 each time the operation state of the ventilation fan is switched. It is possible to detect the condition even with a ventilation fan that is not connected to the network.

The state detection when the opening is a window or a door can be detected by using the infrared sensor 310. The temperature near the opening detected by the infrared sensor 310 and the temperature around the opening are detected and compared. When a window or door is open, outside air enters and exits from the window or door, so that the temperature of the opening is higher than the surroundings when the air conditioner 100 is operating in the cooling state and lower than the surroundings when the air conditioner 100 is operating in the heating state. Is detected. At this time, since it is considered that the opening is open, the state of the opening is detected to be open. In other cases, it is detected as closed. The temperature is detected by the infrared sensor 310 at regular time intervals. The fixed time is, for example, one minute. In addition, for example, every time the open / closed state of a window or door is changed, the state of the opening corresponding to the remote controller 320 is manually input, so that the opening detector 300 detects the state of the opening of the window or door. It is possible.

FIG. 6 is an example of the opening state information detected by the opening detector 300. It consists of an opening number, which is a number that identifies the opening, an opening state, and a corresponding network-connected ventilation fan number. The opening number is the same as that of the opening position information shown in FIG. The opening No. 1 is a ventilation fan 200, which corresponds to the ventilation fan of the ventilation fan number EF01 connected to the network, and is in an air supply state. The opening No. 2 is a window 210 and is in a closed state. The opening No. 3 is a door 220 and is in an open state.

The opening information acquisition unit 500 of the air conditioning control device 110 receives the opening position information indicating the position of the opening in FIG. 5 and the opening state information indicating the state of the opening in FIG. 6 from the opening detector 300. do. Both are collectively called opening information. The opening information acquisition unit 500 integrates information on the position and state of the opening to create opening information. FIG. 7 is an example of opening information. It is composed of an opening number, an air-conditioned area, and an opening state. The created opening information is stored in the opening information storage unit 510.

The wind direction control unit 410 can control the ventilation of air to each of the air-conditioned areas 600 by controlling the direction of the wind direction control plate. By swinging the wind direction control plate up, down, left and right, it is possible to blow air throughout the room. Normal ventilation control is a state in which air is blown to each air-conditioned area 600 for an appropriate time in order to make the temperature distribution in the room even without considering the opening. However, the normal ventilation control does not necessarily have to make the temperature distribution in the room even if there is a more energy-saving method or a comfortable method. For example, even if there is a temperature difference between the ceiling and the floor in the vertical direction, it is okay if the area according to the height of the person is comfortable, and the temperature difference occurs in the horizontal direction as well near the wall and the center of the room. May be. That is, the normal blast control is a blast control that efficiently blows air to each air-conditioned area in order to comfortably air-condition the room, although the opening is not considered.

The wind direction control unit 410 performs wind direction control according to the position and state of the opening. When air-conditioning a room, if there is air inflow and outflow from the opening, the air-conditioning efficiency will decrease. Therefore, by grasping the position of the opening and the state of air supply, exhaust, etc., and controlling the wind direction accordingly, it is possible to prevent a decrease in air conditioning efficiency and enable energy-saving air conditioning.

The wind direction control unit 410 adjusts the time and range of air blowing to provide a windbreak that reduces the amount of air blown than usual and a windbreak that increases the amount of air blown than usual for each air conditioning area 600. It is possible to control the ventilation by setting to. When blowing air to a certain air-conditioned area 600, it is conceivable that the wind will spread to the surrounding air-conditioned area 600, but by adjusting the range of blowing air to the surrounding air-conditioned area 600, it is possible. , It is possible to reduce or increase the amount of air blown to the target air-conditioned area 600.

In the windbreak control, the amount of air blown by shortening the time for blowing air to the corresponding air-conditioned area 600 or changing the air-conditioning range when air-conditioning the surrounding air-conditioned area 600 is increased as compared with the normal air-conditioning control. It is a control to reduce the amount, or a control that does not blow air to the corresponding air-conditioned area 600. When an opening exists in the air-conditioned area 600 and the state of the opening is exhaust, air supply / exhaust, or open, the wind direction control unit 410 sets windbreak control for the air-conditioned area 600. .. At the exhaust, air supply / exhaust, and open openings, indoor air flows out of the room. Therefore, if the temperature-controlled air is blown in the direction of the corresponding opening, the air may be discharged to the outside without being used for indoor temperature control. Therefore, it is possible to increase the efficiency of air conditioning by not blowing air in the direction of the corresponding opening or by reducing the amount of air blown.

In the air-conditioning control, the amount of air blown is increased by lengthening the time for blowing air to the corresponding air-conditioned area 600 or changing the air-conditioning range when air-conditioning the surrounding air-conditioned area 600, as compared with the normal air-conditioning control. It is a control to do. When an opening exists in the air-conditioned area 600 and the state of the opening is air supply, the wind direction control unit 410 sets the wind direction control for the air-conditioned area 600. At the opening in the air supply state, outdoor air flows into the room. Hot air will flow in during cooling and cold air will flow in during heating, which will reduce the air conditioning efficiency. Therefore, by intensively blowing air whose temperature has been adjusted with respect to the inflowing air, the temperature can be adjusted quickly and the decrease in air conditioning efficiency can be prevented.

For the air-conditioned area 600 having no opening, the same wind direction control as during normal control is performed. Further, even if it is an opening, if the opening is in a closed state, it is the most efficient air conditioning control to perform normal control without performing wind direction control. Therefore, normal control is performed and the same wind as usual is applied.

The wind direction control unit 410 reads the opening information from the opening information storage unit 510, and determines the wind direction control of the blown air for each air conditioning area. FIG. 8 is an example of the wind direction control contents for each air-conditioned area. In C of the air-conditioned area, the opening state is the air supply state, and the wind contact is set. The air-conditioned areas I and J are open and windbreaks are set. G in the air-conditioned area is an opening but is in a closed state, and is normally set. Since there are no openings in the other air-conditioned areas, all are set to normal. The wind direction control unit 410 transmits a control signal to the air conditioner 100 in order to blow air with the set wind direction control, and performs wind direction control. In the present embodiment, the windbreak and the wind direction are performed only by controlling the wind direction, but it is also possible to control the air volume. In that case, the air volume control unit 420 also reads the opening information from the opening information storage unit 510 and determines the air volume control for each air conditioning area.

FIG. 9 is a flowchart showing the flow of the wind direction control determination process performed by the wind direction control unit 410. The wind direction control unit 410 determines the wind direction control for each air conditioning area 600. FIG. 9 is a process executed for each air-conditioned area 600. First, the wind direction control unit 410 reads out the opening information of the target air-conditioning area 600 from the opening information storage unit 510 (step S101). Then, it is determined whether or not the opening exists in the target air-conditioning area 600. If the target air-conditioned area 600 exists in the air-conditioned area of the opening information, it is determined that the area is an opening. If there is an opening in the target air-conditioning area 600 (step S102; Y), and if the opening state of the read opening information is any of exhaust, supply / exhaust, and opening (step S103; Y). ), The wind direction control content of the target air conditioning area 600 is set as a windbreak (step S104). If the read opening state is not exhaust, air supply / exhaust, or open (step S103; N), but is in the air supply state (step S105; Y), the wind direction control content of the target air conditioning area 600 is set to the wind direction. (Step S106). If the read opening state is not the air supply state (step S105; N), it means that the opening state is closed, so that the wind direction control content of the target air conditioning area 600 is normally set (step S107). When the opening does not exist in the target air-conditioned area 600 (step S102; N), the wind direction control content of the target air-conditioned area 600 is normally set (step S107).

The process of FIG. 9 is executed for the air-conditioned area 600 in which all the openings are present at the start of operation. Subsequent renewal of wind direction control is performed every time the opening state changes. The wind direction control unit 410 detects a change in the opening information of each air-conditioned area 600, and when the change in the opening state is detected, the process of FIG. 9 is performed on the air-conditioned area 600 in which the opening state has changed. Do and update.

Depending on the size of the air-conditioned area 600, there may be a plurality of openings in one area. In that case, all the target opening information is read out in step S101 of FIG. 9, and in step S103, if any one of the exhaust, supply / exhaust, and open openings exists, it is determined as Y. This is to give priority to preventing the temperature-controlled wind from the air conditioner 100 from being discharged to the outside of the room. Further, in step S105, if even one opening of the supply air exists, it is determined as Y. This is because it is not necessary to consider the content of the wind direction control as long as the opening is in the closed state.

In the above description, the wind direction of the air output by the air conditioner 100 is controlled based on the position and state of the opening, but the air blowing toward the opening during exhaust, intake / exhaust, or opening is stopped or is performed. You may weaken it. For example, the air conditioning control device 110 may control the air conditioner 100 to stop blowing air to the air conditioning area 600g in the room shown in FIG. 4 when the window 210 is open. Similarly, it may be controlled to weaken the blast wind power and the air volume as it approaches the opening that is likely to be exhausted even if the blast is blown. For example, in FIG. 4, it is assumed that the window 210 is open, the door 220 is closed, and the ventilation intensity of the air conditioner 100 is set to “strong”. In this case, for example, the air conditioning control device 110 blows air to the air conditioning regions 600e and 600i with a "strong" air volume, and blows air to the air conditioning regions 600f and 600h at 70% of the normal "strong" air volume and wind speed. The air-conditioned area 600 g may be controlled to weaken the blown wind and air volume as it approaches an opening that is likely to be exhausted, such as blowing air at an air volume and wind speed of 49% of the normal “strong”. Wind and volume adjustments can be gradual or continuous.

The operation of the air conditioning control device 110 is the same as that of the first embodiment. On the other hand, the air conditioning unit 120 controls the wind direction for sending the harmonized air according to the control of the air conditioning control device 110. As a specific method for controlling the wind direction, the directions of the built-in vanes and flaps may be adjusted. As a result, as in the first embodiment, the position of the opening and the state of air supply, exhaust, etc. are grasped, and the wind direction is controlled accordingly, thereby preventing the deterioration of the air conditioning efficiency and enabling energy-saving air conditioning. do.

FIG. 11 is a diagram showing a hardware configuration example of the air conditioning control device 110 according to the first embodiment of the present invention and the air conditioner 100 according to the second embodiment.

The processor 51 is a CPU (Central Processing Unit) that executes a program stored in the memory 52.

Software and firmware are described as programs and stored in the memory 52. The processor 51 realizes the functions of each part by reading and executing the program stored in the memory 52. That is, when the air conditioner control device 110 and the air conditioner 100 are executed by the processor 51, the step of controlling the wind direction control unit 410, the air volume control unit 420, and the opening information acquisition unit 500 is eventually executed.
