Description

  The present invention relates to an air conditioning operation device for operating and operating air conditioning efficiently and an air conditioning management system using the same.

  2. Description of the Related Art Conventionally, there is an air conditioning management system having an air conditioning control device in order to achieve suitable control of individual air conditioning (for example, see Patent Document 1). In Patent Document 1, an air conditioner is controlled based on data obtained by digitizing user's intention information with respect to room temperature. Here, although the user's intention of the air conditioner depends on the user's preference, it is generally determined for comfort and / or economy.

  However, the driving control based on the user's intention information for obtaining comfort and economy is not necessarily the control having the comfort and economy as requested by the user. That is, there is a problem that although it is consistent with the user's intention, not only the comfort that the user abandoned but also the economy that the user tried to acquire cannot be obtained.

  For example, it is assumed that the user has an intention to delay the timing of operating the air conditioning by putting up the heat at high temperatures and giving up comfort in order to obtain economic efficiency. Even in this case, in practice, operating the air conditioner at a timing earlier than the user's intention and before the high air temperature is economical in terms of maximizing the heat pump performance of the air conditioner. There is. In particular, when the temperature is severe, there is a risk that the user will endure the heat for economic efficiency, and the physical condition such as heat stroke may become poor, so respect for the user's intention is not always appropriate control. .

  Further, even if there is a system capable of performing appropriate control, there is a problem that it is difficult to introduce the system. For example, there is already a management system (HEMS: Home Energy Management System) for saving energy used at home, but there are physical difficulties when the air conditioning equipment is systematically independent at present, In the case of rental housing, there is a real difficulty because the introduction of the system depends on the intention of the lender and the economic burden of introducing the system is large.

The obtained operating condition (Dg) is to operate the air conditioning equipment (AC) through the air conditioning operation device (20) at an appropriate timing determined based on the weather forecast. Then, it becomes possible to feed back the suitable operating condition (Dg) calculated by the air conditioning management device (10) to the individual air conditioning equipment (AC), and the user can operate the air conditioning equipment (AC) without being aware of it. It can be done at an appropriate time. Therefore, it is possible to appropriately manage individual air conditioning equipment (AC) and provide an air conditioning management system (1) that is excellent in comfort and economy.

  In the air conditioning management system (1), the arithmetic control unit (12) calculates the device usage tendency (D3) of the air conditioning equipment (AC) by analyzing the power consumption data (D1), and the power consumption data ( D1) and weather data (D2) are analyzed to create a temperature-power consumption relationship diagram (D4), which is more efficient based on equipment usage trends (D3) and temperature-power consumption relationship diagram (D4).

  Hereinafter, an embodiment in which an air conditioning operation device 20 of the present invention is applied to an air conditioning management system 1 will be described in detail with reference to the accompanying drawings. FIG. 1 is an overall explanatory diagram of the air conditioning management system 1. As shown in FIG. 1, the air conditioning management system 1 includes an air conditioning management device 10 that includes an arithmetic control unit 12 and an air conditioning operation device 20 that includes an operation control unit 22 of an air conditioning facility AC. The air conditioning management device 10 and the air conditioning operation device 20 can communicate with each other via an external communication network IT (Internet), and the communication network IT includes a weather information providing unit 40. Next, each part will be described in detail.

  The air conditioning facility AC is generally equipped with a device that indicates the amount of power consumption, and the amount of power consumption can be ascertained from the outside through a signal from the communication unit 31. Further, the air conditioning equipment AC has an operation signal receiving unit 32, which is operated by receiving a signal such as infrared rays from a general driving operation device (remote control) (not shown). Examples of the air conditioning equipment AC include a heat pump type air conditioner by inverter control. A heat pump type air conditioner is characterized in that the energy consumption decreases as the temperature difference between the outside air temperature and the room temperature decreases.

  The air-conditioning management apparatus 10 includes a communication unit 11 that transmits and receives data, an arithmetic control unit 12 that performs control based on data obtained from the communication unit 11, and storage of acquired data and data obtained as a result of calculation And a storage unit 13 that performs storage. The air conditioning management device 10 is a computer such as a server connected to the communication network IT.

  The communication unit 11 transmits and receives data using a wired or wireless communication unit. Specifically, data from the air conditioning operation device 20 and the weather information providing unit 40 is received through the communication network IT, or data is transmitted to the air conditioning management device 10 through the communication network IT.

  The arithmetic control unit 12 is mounted with a CPU and the like, selects data obtained via the communication network IT using the communication unit 11, calculates based on the data obtained from the communication unit 11, and operates a suitable air conditioner AC. The operating condition is calculated and transmitted to the air conditioning operation device 20 using the communication unit 11. Specific data and a specific calculation method will be described later.

  The storage unit 13 stores (stores) data acquired by the communication unit 11 and data calculated by calculation by the calculation control unit 12. For example, various storage media such as a hard disk, a memory, a DVD disc, and a Blu-ray disc capable of reading and writing data, including storage media that will be developed in the future.

  The air conditioning operation device 20 includes a communication unit 21 that transmits and receives data, an operation control unit 22 that performs control based on data obtained from the communication unit 21, and storage of acquired data and data obtained as a result of calculation. It has the memory | storage part 23 which performs storage, and the transmission part 24 which performs a driving | operation instruction | indication with respect to air-conditioning equipment AC. The air conditioning operation device 20 is a small terminal disposed in the same room as the air conditioning facility AC, and may be supplied with power from a household power source (not shown) or may be supplied with a battery.

  The communication unit 21 transmits and receives data using a wired or wireless communication unit. Specifically, data on the amount of power consumption of the air conditioning facility AC is received, data received from the air conditioning facility AC is transmitted to the air conditioning management device 10, or data from the air conditioning management device 10 is received through the communication network IT. Or Here, the data communication from the air conditioning operation device 20 to the air conditioning management device 10 may be performed via the communication network IT or directly.

  The operation control unit 22 is mounted with a CPU or the like and processes data obtained from the communication unit 21. For example, the communication unit 31 issues an instruction to transmit the data obtained by the communication unit 21 to the air conditioning management device 10, the data obtained from the air conditioning management device 10 is stored in the storage unit 23, or the data stored in the storage unit 23 Is transmitted to the operation signal receiving unit 32 of the air conditioning equipment AC by the transmission unit 24.

  The storage unit 23 stores (stores) data acquired by the communication unit 21. For example, various storage media such as a hard disk, a memory, a DVD disc, and a Blu-ray disc capable of reading and writing data, including storage media that will be developed in the future.

  The transmission unit 24 issues a signal for performing an operation instruction to the operation signal reception unit 32 of the air conditioning equipment AC. The transmission unit 24 preferably performs data transmission using infrared rays. This is because a general air-conditioning equipment AC operation control device is operated by infrared rays. Note that the operation signal is not necessarily transmitted using infrared rays.

  The weather information providing unit 40 is a weather information providing service connected to the communication network IT. Information from the weather information providing unit 40 includes position information such as altitude, latitude, and longitude in addition to meteorological information such as temperature, humidity, atmospheric pressure, sunshine, and weather. The weather information providing unit 40 is not necessarily limited to information provided by one organization, and may comprehensively determine information provided by a plurality of organizations.

  Next, an example of a procedure until a suitable operating condition Dg is obtained using the air conditioning management system 1 having the above configuration will be described. FIG. 2 is a flowchart showing a control procedure of the air conditioning management system 1.

  First, in the air conditioning management system 1, as shown in FIG. 2, the air conditioning operation device 20 acquires power consumption data D <b> 1 that is data of the power consumption amount transmitted from the communication unit 31 of the air conditioning facility AC by the communication unit 21. (Step S1). In step S1, the frequency of acquiring data may be constantly acquired during operation of the air conditioning equipment AC, or may be acquired intermittently by specifying a time.

  The power consumption data D1 obtained by the air conditioning operation device 20 is transmitted from the communication unit 21 to the communication unit 11 and acquired by the air conditioning management device 10 (step S2). In step S2, data may be transmitted directly from the communication unit 21 to the communication unit 11 via the communication network IT.

  Moreover, the air-conditioning management apparatus 10 acquires the weather data D2 from the weather information provision part 40 via communication network IT (step S3). Since the meteorological data obtained by the meteorological information providing unit 40 includes meteorological information and position information as described above, the meteorological data needs to be the meteorological data D2 of the area where the air conditioning equipment AC exists.

  For convenience of explanation, step S3 has been described after step S1 and step S2, but the order is not necessarily limited to this. Since the power consumption data D1 and the weather data D2 are data obtained independently of each other, step S1, step S2, and step S3 are in no particular order. Further, the data obtained by the communication unit 11 is appropriately stored in the storage unit 13 by the arithmetic control unit 12 and accumulated as necessary.

  Then, the arithmetic control unit 12 of the air conditioning management device 10 analyzes the power consumption data D1 and the weather data D2 (step S4). Thereby, the data of the suitable driving conditions Dg are created based on the weather forecast (step S5). The procedure for obtaining suitable operating conditions Dg will be described in detail later.

  The operating condition Dg obtained by the air conditioning management device 10 is transmitted from the communication unit 11 to the communication unit 21, and the air conditioning operation device 20 acquires a suitable operating condition Dg (step S6). The operation control unit 22 stores the operation condition Dg obtained by the communication unit 21 in the storage unit 23 as appropriate. Thereafter, the air conditioning operation device 20 appropriately operates the air conditioning equipment AC by transmitting the operating condition Dg to the air conditioning equipment AC at an appropriate timing Tg (step S7).

  Next, a procedure until the calculation control unit 12 analyzes the power consumption data D1 and the weather data D2 and creates data of suitable operating conditions Dg based on the weather forecast will be described in detail. FIG. 3 is a flowchart showing in detail the control procedure by the arithmetic control unit 12. In FIG. 3, step S4 and step S5 in FIG. 2 are described in detail.

  The arithmetic control unit 12 accumulates the power consumption data D1 obtained from the communication unit 11 in the storage unit 13, and analyzes the accumulated power consumption data D1 (step S4a). Thereby, the apparatus usage tendency D3 for every user is calculated (step S4b). The device usage tendency D3 is, for example, a graph representing how the power consumption has changed at any time.

  On the other hand, the arithmetic control unit 12 analyzes the power consumption data D1 and the weather data D2 while accumulating in the storage unit 13 (step S4c). Thereby, the temperature-power consumption relationship diagram D4 is created (step S4d).

  Next, the arithmetic control unit 12 compares the data from the device usage trend D3 and the temperature-power consumption relationship diagram D4, and calculates an operating condition Dg that is more efficient than the user device usage trend D3 (step S5a). ).

  Thereafter, the arithmetic control unit 12 creates the predicted temperature data D5 by analyzing the weather data D2 (step S5b). Then, based on the predicted temperature data D5, the air conditioning operation device 20 determines a suitable timing Tg for operating the air conditioning equipment AC under the operating condition Dg (step S5c).

  A suitable operation condition Dg by the arithmetic control unit 12 whose procedure has been described with reference to FIG. 3 and a suitable timing Tg at which the air conditioning operation device 20 transmits the operation condition Dg to the air conditioning equipment AC will be described with reference to FIGS. I will explain it. FIG. 4 is a graph showing an example of how the device usage trend D3 is grasped from the power consumption data D1.

  As shown in FIG. 4, the arithmetic control unit 12 accumulates the power consumption data D1 obtained from the communication unit 11 in the storage unit 13 for each time, and arranges the accumulated power consumption data D1 for each time. Thereby, the apparatus usage tendency D3 can be graphed and a user's usage tendency can be grasped | ascertained. For example, according to the example of FIG. 4, the user of the air conditioning equipment AC turns on the power supply of the air conditioning equipment AC at time Ta1, turns off the power supply of the air conditioning equipment AC at time Ta2, and again turns on the power supply of the air conditioning equipment AC at time Ta3. It turns out that is turned on.

  The arithmetic control unit 12 accumulates the weather data D2 in the storage unit 13 and analyzes it. In FIG. 4, the temperature (outside temperature) in the weather data D2 is represented by a graph according to the time. And the temperature-power consumption relationship diagram D4 is created by overlapping the above-described device usage tendency D3 and the outside air temperature. Then, the relationship between the outside air temperature and the power consumption corresponding to each time can be grasped.

  By analyzing from the temperature-power consumption relationship D4 in FIG. 4, for example, the user of the air conditioning equipment AC of this case turns on the power at the time Ta1 when the outside air temperature becomes Ca or higher. Even when the air conditioner AC is turned off (at time Ta2) in a steady state, when the outside air temperature is equal to or higher than Ca, the time Ta3 when a relatively short time has passed since the power was turned off. It can be seen that there is a tendency to turn on the power again at the time of. In this case, it can be seen that this user tends to turn on the power when the outside air temperature is Ca or higher.

  FIG. 5 is a graph showing an example of a procedure for obtaining the operating condition Dg from the temperature-power consumption relationship D4. (A) is a graph representing the device usage tendency D3, (b) is a graph representing the operating condition Dg, and (c) is a graph in which the device usage tendency D3 and the operating condition Dg are overlapped.

  The arithmetic control unit 12 compares and examines data from the device usage tendency D3 and the temperature-power consumption relationship diagram D4 as shown in FIG. Then, an efficient operating condition Dg is calculated from the user's device usage tendency D3. For example, as shown in FIG. 5B, the power is turned on at an external temperature Cg lower than the external temperature Ca at which the user turns on the power, and at a timing Tg that is earlier than time Ta1 when the user tends to turn on the power. An operating condition Dg that turns ON is calculated. Here, in the operation condition Dg, unlike the user, control that does not turn off the power is calculated.

  In this case, when the graph of the operating condition Dg is superimposed on the graph of the device usage tendency D3 as shown in FIG. 5C and the difference in the total amount of power consumption within a predetermined time is measured, the power consumption due to the operating condition Dg It can be seen that the sum of the amount Sg1 and the power consumption Sg2 is smaller than the sum of the power consumption Sa1 and the power consumption Sa2 due to the device usage tendency D3 of the user. That is, the operating condition Dg that does not switch the power ON and OFF in a short time is more efficient than the user device usage tendency D3 that switches the power ON and OFF in a short time. The calculation control part 12 is calculating | requiring the operation condition Dg more suitable than a user by calculating so that it may become such a calculation result.

  FIG. 6 is a graph showing an example of a procedure for determining the timing Tg for operating the air conditioning equipment AC. In the example of FIG. 6, in order to simplify the description, an example is given in which the temperature change tendency when obtaining the operating condition Dg and the temperature change tendency of the predicted temperature data D5 are similar.

  As shown in FIG. 6, the arithmetic control unit 12 analyzes the weather data D2 to create predicted temperature data D5 of the area where the air conditioning equipment AC exists. Then, it is determined from the aforementioned operating condition Dg that the power supply of the air conditioning equipment AC is turned on at the timing Tg when the outside air temperature becomes Cg. Then, at the time Ta2 described above, it is determined not to turn off the power but to keep it on.

  With the configuration as described above, in the air conditioning operation device 20 of the present embodiment that operates the air conditioning facility AC, the operation control unit 22 transmits the operation condition Dg obtained by the communication unit 21 to the transmission unit 24. The air conditioner AC is operated by According to this, when a suitable operation condition Dg is obtained from the outside, the operation control unit 22 can transmit the operation condition Dg to the existing air conditioning equipment AC using the transmission unit 24. For this reason, it becomes possible to feed back suitable operating conditions Dg to the individual air conditioning equipment AC. This makes it possible to easily introduce efficient operation information data such as HEMS into the existing air conditioning equipment AC. Therefore, the air conditioning management system 1 that appropriately manages the individual air conditioning equipment AC and is excellent in comfort and economy can be applied to the existing air conditioning equipment.

  Moreover, in the said air-conditioning operation apparatus 20, the transmission part 24 is good also as transmitting data by infrared rays. As described above, if the air conditioning facility AC is operated by infrared communication that is generally used, it can be easily introduced into the existing general air conditioning facility AC.

  Moreover, when it is set as the air-conditioning management system 1 which has the said air-conditioning operation apparatus 20, the calculation control part 12 of the air-conditioning management apparatus 10 not only analyzes the power consumption data D1 of air-conditioning equipment AC, but the area where air-conditioning equipment AC exists. By analyzing the weather data D2, a specific and efficient operating condition Dg of the individual air conditioning equipment AC can be obtained. Further, the obtained operating condition Dg is to operate the air conditioning equipment AC through the air conditioning operation device 20 at an appropriate timing determined based on the weather forecast. Then, it becomes possible to feed back the suitable operating condition Dg calculated by the air conditioning management device 10 to the individual air conditioning equipment AC, and the air conditioning equipment AC can be operated at an appropriate timing without the user being aware of it. . Therefore, it is possible to appropriately manage the individual air conditioning equipment AC and provide the air conditioning management system 1 that is excellent in comfort and economy.

  Moreover, in the said air-conditioning management system 1, if the apparatus usage tendency D3 of air-conditioning equipment AC is calculated by analyzing the power consumption data D1, it will become possible to discover the improvement point in operation of an individual user. Further, if the temperature-power consumption relationship diagram D4 is created by analyzing the power consumption data D1 and the weather data D2, it is possible to find an improvement in the operation of the individual air conditioning equipment AC with respect to the outside temperature. Become. Here, by calculating the more efficient operating condition Dg based on the device usage tendency D3 and the temperature-power consumption relationship diagram D4, it is possible to operate the air conditioning equipment AC appropriately.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Deformation is possible.
