Description

Area

[0001] The present disclosure relates to an air conditioning system and an air conditioning system, each comprising an indoor unit and an outdoor unit which communicate with each other. background

[0002] To enable condition detection within an air conditioning system, the system typically receives data representing its operating conditions. This data is used for operational management, such as monitoring operating conditions, troubleshooting, and inspection. Increasingly, air conditioning systems are being manufactured with a function to transmit this data to an external device, such as a cloud, for remote operational management. An increase in the number of data elements used for operational management leads to an increase in the amount of data transmitted to the external device. Therefore, a configuration is known in which data is only transmitted if the rate of change in the data exceeds a certain threshold.

[0003] For example, patent literature 1 discloses a technology which reduces the amount of data transmitted to an external device, called a remote monitoring device, in a system in which such an external device collects data from each of several control and measuring devices via a network, in such a way that the external device returns requested data when it is determined that the rate of change of the data to be transmitted exceeds a certain range, while the external device returns short data, which merely confirms receipt of the request, when the rate of change falls within the determined range. List of patent literature

[0004] Patent literature 1: Japanese patent application, publication number 2006 - 235 797 (JP 2006 - 235 797 A) Brief description of the invention Problem to be solved by the invention

[0005] However, when the conventional technology described above is applied to an air conditioner, the amount of data transmitted to the external unit can indeed be reduced if the number of data elements used for operational management has increased. However, such an increase in turn causes an increase in the amount of data transmitted between the indoor and outdoor units. Not only data used for operational management, but also data used to control the air conditioner, is transmitted between the indoor and outdoor units. This presents a problem in that an increase in the number of data elements used for operational management weakens the real-time nature of the data used to control the air conditioner.

[0006] The present disclosure was made in view of the above, and one objective of the present disclosure is to provide an air conditioning system designed to reduce the amount of data transmitted between an indoor unit and an outdoor unit, and therefore to reduce the impact on the transmission and reception of data for use in controlling the air conditioning system, even when there is an increase in the number of data elements to be used for operational management. Means to solve the problem

[0007] To solve the problems described above and achieve the objective, an air conditioning system according to the present disclosure comprises: an operating value reference unit which obtains operating values, wherein the operating values ​​are each a value obtained in association with an operation of the air conditioning system; a calculation unit which calculates a comparison reference value based on the operating values; a determination unit which, based on a difference between the comparison reference value and a current operating value of the operating values ​​obtained by the operating value reference unit, determines whether an operating value of the operating values ​​is a transfer object to be transferred between an indoor unit and an outdoor unit;and a communication unit which, according to a determination result of the determination unit, transmits an operating value of the operating values ​​determined as a transfer object to be transferred between the indoor unit and the outdoor unit, and does not transmit an operating value of the operating values ​​not determined as a transfer object to be transferred between the indoor unit and the outdoor unit. Effects of the invention

[0008] The present disclosure provides an advantageous effect in that an air conditioning system can be provided which is designed to reduce the amount of data transmitted between an indoor unit and an outdoor unit and therefore to reduce the impact on the transmission and reception of data for use in controlling the air conditioning system, even if there is an increase in the number of data elements to be used for operational management.

Description of embodiments

[0009] An air conditioning system and an air conditioning system according to embodiments of the present disclosure are described in detail below with reference to the drawings. In the drawings and the following description, components designated by identical reference numerals are components with a function or functions that are the same or similar to one another. Furthermore, the sizes of the components shown in the drawings are not necessarily the actual sizes, and the relative sizes of the components are not necessarily shown in their actual proportions. The shapes of components are given in the following description only as examples and are not limited to the shapes shown. For example, not all components described in this description are necessarily included.In particular, the combinations of components are not limited to the combinations given in the embodiments, but a component described in one embodiment can be used in another embodiment. First embodiment.

[0010] Fig. Figure 1 is a diagram showing a configuration of an air conditioner 10A according to a first embodiment. The air conditioner 10A comprises an outdoor unit 1 and an indoor unit 2. Although Fig. Figure 1 shows only a single outdoor unit 1 and a single indoor unit 2, it should be noted that the single outdoor unit 1 can be connected to several indoor units 2. Fig. Figure 2 is a diagram showing an example where a single outdoor unit 1 is connected to four indoor units 2-1 to 2-4. As shown in Fig. As shown in Figure 2, it should be noted that the inner units 2 can be distinguished from each other by different suffix numbers, which are associated with the respective inner units 2 after a common reference sign with a hyphen in between.

[0011] Referring again to the description of Fig. 1 The outdoor unit 1 comprises a communication unit 12 matching the indoor unit, which communicates with the indoor unit 2, and a calculation unit 11, which calculates a comparison reference value based on an operating value received from the indoor unit 2.

[0012] An operating value is a value obtained in association with the operation of the air conditioner 10A. Operating values ​​obtained by the indoor unit 2 are hereinafter referred to as an indoor unit operating value, and operating values ​​obtained by the outdoor unit 1 are hereinafter referred to as an outdoor unit operating value. In the first embodiment, indoor unit operating values ​​are obtained. The indoor unit operating values ​​each comprise at least one piece of information, for example, indoor environmental information such as the temperature and / or humidity of the room where the indoor unit 2 is installed, or operating information obtained through the operation of the air conditioner 10A. The environmental information is information obtained by a sensor, for example, a temperature sensor or a humidity sensor.The operating information is a function setting value, operating setting information, and the like, for example, an operating mode, a set temperature, and a set humidity, during or for the operation of the air conditioner 10A. The comparison reference value, as described in more detail later, is a criterion for determining whether an indoor unit operating value obtained by indoor unit 2 is a transmission object to be transferred to outdoor unit 1.

[0013] The communication unit 12, which is compatible with the indoor unit, comprises a transmission unit 121, which transmits data to the indoor unit 2, and a receiving unit 122, which receives data from the indoor unit 2. In particular, the transmission unit 121 transmits the comparison reference value calculated by the calculation unit 11 to the indoor unit 2, and the receiving unit 122 receives an indoor unit operating value from the indoor unit 2.

[0014] The indoor unit 2 comprises an indoor unit determination unit 21, an outdoor unit-compatible communication unit 22, and an indoor unit operating value reference unit 23, wherein the indoor unit determination unit 21 determines whether a current indoor unit operating value is a transmission object to be transferred to the outdoor unit 1, based on the difference between the comparison reference value and the indoor unit operating value; the outdoor unit-compatible communication unit 22 communicates with the outdoor unit 1; and the indoor unit operating value reference unit 23 receives the indoor unit operating value.

[0015] The indoor unit determination unit 21 is a determination unit that receives the comparison reference value from the outdoor unit 1 via the communication unit 22 that corresponds to the outdoor unit. Upon receiving an indoor unit operating value from the indoor unit operating value reference unit 23, it determines, based on the difference between the comparison reference value and the current indoor unit operating value, whether the current indoor unit operating value is a transmission object to be transferred between the indoor unit 2 and the outdoor unit 1. For example, the indoor unit determination unit 21 compares the difference between the comparison reference value and the current indoor unit operating value with a first threshold value.Then, if the difference is greater than or equal to the first threshold, the indoor unit determination unit 21 determines that the current indoor unit operating value is a transferable transfer object and transfers the current indoor unit operating value to the outdoor unit 1, whereas if the difference is less than the first threshold, the indoor unit determination unit 21 determines that the current indoor unit operating value is not a transferable transfer object and does not transfer the current indoor unit operating value to the outdoor unit 1.

[0016] The communication unit 22, which is compatible with the outdoor unit, comprises a receiving unit 221, which receives data from the outdoor unit 1, and a transmitting unit 222, which transmits data to the outdoor unit 1. In particular, the receiving unit 221 receives the comparison reference value from the outdoor unit 1, and the transmitting unit 222 transmits the indoor unit operating value obtained by the indoor unit operating value reference unit 23 to the outdoor unit 1.

[0017] The indoor unit operating value reference unit 23 receives an indoor unit operating value and outputs the received indoor unit operating value to the indoor unit determination unit 21.

[0018] Fig. Figure 3 is a flowchart describing a procedure for determining the comparison reference value, which is described in Fig. The process is carried out by the outdoor unit 1 shown. The outdoor unit 1 receives an indoor unit operating value from the indoor unit 2 using the receiving unit 122 of the indoor unit-compatible communication unit 12 (step S11). The calculation unit 11 of the outdoor unit 1 calculates the comparison reference value from the received indoor unit operating value (step S12). The outdoor unit 1 transmits the calculated comparison reference value to the indoor unit 2 using the transmission unit 121 of the indoor unit-compatible communication unit 12 (step S13).

[0019] A procedure used by the calculation unit 11 to calculate the comparison reference value is described next. Fig. Figure 4 is a diagram illustrating a first example of a procedure for calculating the reference value. In this first example, the computation unit 11 calculates the reference value for each of the indoor units 2 based on the operating value obtained in the respective indoor unit 2. In this case, the reference value is calculated for each of the multiple indoor units 2. For example, the computation unit 11 calculates the reference value using multiple operating values ​​obtained during a reference value determination period of a predetermined length, from the present to the past. The reference value can be an average, median, maximum, minimum, or similar value of multiple operating values.

[0020] Fig. Figure 5 is a diagram illustrating a second example of the procedure for calculating the reference value. In this second example, the computation unit 11 calculates the reference value based on indoor unit operating values ​​obtained by the multiple indoor units 2 connected to the outdoor unit 1. In this case, a common value for the multiple indoor units 2 is calculated as the reference value. For example, the computation unit 11 can calculate and use an average, median, maximum, minimum, or similar value of the multiple indoor unit operating values ​​obtained by the multiple indoor units 2 as the reference value. Fig. Since 5 displays a single operating value for each of the indoor units 2, the calculation unit 11 can calculate the comparative reference value for each of the respective indoor units 2 using multiple indoor unit operating values ​​obtained during the comparative reference value determination period. Determining the comparative reference value using indoor unit operating values ​​from multiple indoor units 2 allows for the determination of environmental information for each of the rooms where the indoor units 2 are installed.

[0021] Fig. Figure 6 is a flowchart describing a procedure for transferring an indoor unit operating value to outdoor unit 1, as described in Fig. The process is carried out on the indoor unit 2 shown in step 1. The indoor unit operating value reference unit 23 of indoor unit 2 receives an indoor unit operating value (step S21). The indoor unit determination unit 21 calculates a difference between the obtained indoor unit operating value and the comparison reference value (step S22).

[0022] The indoor unit determination unit 21 determines whether the calculated difference is greater than or equal to a first threshold (step S23). If the difference is greater than or equal to the first threshold (step S23: Yes), the indoor unit determination unit 21 transmits the received current indoor unit operating value to the outdoor unit 1 using the outdoor unit-matching communication unit 22 (step S24). If the difference is less than the first threshold (step S23: No), the operation of step S24 is skipped and the current indoor unit operating value is therefore not transmitted to the outdoor unit 1.

[0023] In the Fig. In example 4, the current indoor unit operating value falls within a first threshold range, which is a range in which the difference between the current indoor unit operating value and the comparison reference value is smaller than the first threshold. Therefore, the current indoor unit operating value is not transmitted to outdoor unit 1. Furthermore, in the example shown... Fig. In example 5, the indoor unit operating values ​​of indoor units 2-1 and 2-2 are within the first threshold range and are therefore not transferred to outdoor unit 1, whereas the indoor unit operating values ​​of indoor units 2-3 and 2-4 are outside the first threshold range and are therefore transferred to outdoor unit 1.

[0024] It should be noted that if several types of operating values ​​are obtained, a comparison reference value is determined for each type of operating value, and the indoor unit determination unit 21 calculates the difference between the current indoor unit operating value and the comparison reference value for the respective type of operating value in order to compare the calculated difference with the first threshold value. Preferably, the first threshold value is also set for the respective type of operating value. The first threshold value for the respective type of operating value is determined to avoid influencing any control performed during operation of the air conditioner 10A. For example, the non-transmission of a suction temperature, which is used in a display on a remote control, does not affect the display as long as its temperature change falls within a displayable resolution range.In a case where the outdoor unit 1 calculates an average of the suction temperatures of the indoor units 2 and determines that the average is the reference value, the indoor unit 2 can therefore reduce a communication load by not transmitting suction temperature data to the outdoor unit 1 if the difference between the current suction temperature and the reference value is within the first threshold.

[0025] As described above, the air conditioning system 10A according to the first embodiment comprises the indoor unit operating value reference unit 23, which is an operating value reference unit that obtains an indoor unit operating value, which is an operating value that is obtained in association with the operation of the air conditioning system 10A; the calculation unit 11, which calculates a comparison reference value based on the indoor unit operating value; the indoor unit determination unit 21, which is a determination unit that determines, based on the difference between the comparison reference value and the current indoor unit operating value obtained by the indoor unit operating value reference unit 23, whether the indoor unit operating value is a transmission object to be transmitted between the indoor unit 2 and the outdoor unit 1; and the outdoor unit-compatible communication unit 22.which, according to a determination result of the indoor unit determination unit 21, is a communication unit that transmits an indoor unit operating value, which is defined as a transmission object, between the indoor unit 2 and the outdoor unit 1, in particular from the indoor unit 2 to the outdoor unit 1. In the first embodiment, the operating value, which is defined as the transmission object, is limited to the time of the transmission of the indoor unit operating value, which is an operating value obtained in the indoor unit 2, to the outdoor unit 1. This allows a reduction in the amount of data transmitted between the indoor unit 2 and the outdoor unit 1 and therefore allows a reduction in the impact on the transmission and reception of data for use in controlling the air conditioning system 10A, even if there is an increase in the number of data elements to be used for operational management.

[0026] In this respect, the operating value obtained by the indoor unit operating value reference unit 23 comprises an operating value of at least one from an environmental information which is obtained from a measurement of a state of an environment, and an operating information which represents an operating condition of the air conditioning system 10A.

[0027] Furthermore, the calculation unit 11 can determine the comparative reference value based on at least one of an average, a maximum, and a minimum value from several operating values. For example, the calculation unit 11 can itself determine the average, maximum, or minimum value of several operating values ​​as the comparative reference value, or it can determine a value calculated based on at least one of the average, maximum, and minimum values ​​from several operating values ​​as the comparative reference value. It should be noted that the several operating values ​​used by the calculation unit 11 to calculate the comparative reference value can be operating values ​​obtained by a single indoor unit 2 or by several indoor units 2.

[0028] If the indoor unit operating value reference unit 23 receives several types of operating values, the calculation unit 11 also calculates a comparison reference value for each type of operating value. The first threshold value can also be set for each type of operating value.

[0029] The indoor unit determination unit 21 determines that an operating value is a transferable transfer object, for example, if the difference between the operating value and the comparison reference value is greater than or equal to a first threshold value. The indoor unit determination unit 21 only transfers an operating value to the outdoor unit 1 that is determined as a transferable transfer object, and does not transfer an operating value to the outdoor unit 1 that is not determined as a transferable transfer object. Second embodiment.

[0030] Fig. Figure 7 is a diagram showing a configuration of an air conditioner 10B according to a second embodiment. The air conditioner 10B comprises an outdoor unit 1B and an indoor unit 2. Components that are identical or similar to corresponding components of the air conditioner 10A according to the first embodiment are designated by identical reference numerals, and their detailed descriptions are omitted. The following description mainly describes differences from the first embodiment.

[0031] The air conditioner 10B receives an operating value not only from indoor unit 2 but also from outdoor unit 1B. An outdoor unit operating value, which is an operating value obtained by outdoor unit 1B, is also processed in such a way that, when transferred to indoor unit 2, the operating value to be transferred to indoor unit 2 is limited based on the difference between the operating value and the reference value. A detailed configuration and operating procedure are described below.

[0032] The outdoor unit 1B comprises a calculation unit 11B, which calculates the comparison reference value; the communication unit 12, which communicates with the indoor unit 2; an outdoor unit determination unit 13, which determines whether data is a transmission object to be transferred from the outdoor unit 1B to the indoor unit 2; and an outdoor unit operating value reference unit 14, which receives an outdoor unit operating value.

[0033] In addition to the functions of the outdoor unit 1's calculation unit 11, calculation unit 11B has a function for calculating a comparative reference value to determine whether an outdoor unit operating value is a transfer object to be transmitted from outdoor unit 1B to indoor unit 2, based on the outdoor unit operating value obtained by the outdoor unit operating value reference unit 14. Calculation unit 11B calculates a comparative reference value for an outdoor unit operating value according to a detailed procedure that is identical to the procedure for calculating a comparative reference value for an indoor unit operating value. Calculation unit 11B outputs the comparative reference value calculated for an outdoor unit operating value to the outdoor unit determination unit 13.

[0034] The outdoor unit determination unit 13 is a determination unit that receives the comparison reference value from the calculation unit 11B and, upon receiving an outdoor unit operating value from the outdoor unit operating value reference unit 14, determines, based on the difference between the comparison reference value and the current outdoor unit operating value, whether the current outdoor unit operating value is a transfer object to be transferred between outdoor unit 1 and indoor unit 2. For example, the outdoor unit determination unit 13 compares the difference between the comparison reference value and the current outdoor unit operating value with the first threshold value.Then, if the difference is greater than or equal to the first threshold, the outdoor unit determination unit 13 determines that the current outdoor unit operating value is a transferable transfer object and transfers the current outdoor unit operating value to the indoor unit 2, whereas if the difference is less than the first threshold, the outdoor unit determination unit 13 determines that the current outdoor unit operating value is not a transferable transfer object and does not transfer the current outdoor unit operating value to the indoor unit 2.

[0035] The outdoor unit operating value reference unit 14 is configured to obtain an outdoor unit operating value and output this value to the calculation unit 11B and the outdoor unit determination unit 13. An outdoor unit operating value is a value obtained by the outdoor unit 1B from the operating values, which are values ​​obtained in association with the operation of the air conditioning system 10B. The outdoor unit operating value is information that includes at least one piece of environmental information, such as the temperature and / or humidity of the surrounding environment in which the outdoor unit 1B is installed, and operating information obtained through the operation of the air conditioning system 10B.

[0036] It should be noted that a procedure for determining a comparison reference value, which is performed by outdoor unit 1B, is one which is obtained by reading "Outdoor Unit 1B" for "Indoor Unit 2" and reading "Outdoor Unit Operating Value" for "Indoor Unit Operating Value" in the procedure which is related to Fig. 3 is described in the first embodiment, and its detailed description is therefore omitted.

[0037] Furthermore, a procedure for transferring an outdoor unit operating value to indoor unit 2, which is carried out by outdoor unit 1B, is one which is obtained by reading "outdoor unit 1B" for "indoor unit 2", reading "outdoor unit operating value" for "indoor unit operating value" and reading "indoor unit 2" for "outdoor unit 1" in the procedure which is related to Fig. 6 is described in the first embodiment, and its detailed description is therefore omitted.

[0038] As described above, the air conditioning unit 10B according to the second embodiment comprises the outdoor unit operating value reference unit 14, which is an operating value reference unit that receives an outdoor unit operating value, which is an operating value obtained in association with the operation of the air conditioning unit 10B; the calculation unit 11B, which calculates a comparison reference value based on the outdoor unit operating value; the outdoor unit determination unit 13, which is a determination unit that, based on the difference between the comparison reference value and the current outdoor unit operating value obtained by the outdoor unit operating value reference unit 14, determines whether the outdoor unit operating value is a transmission object to be transferred between the indoor unit 2 and the outdoor unit 1B;and the indoor unit-compatible communication unit 12, which is a communication unit that, according to a determination result of the outdoor unit determination unit 13, transmits an outdoor unit operating value defined as a transmission object between the indoor unit 2 and the outdoor unit 1B, in particular from the outdoor unit 1B to the indoor unit 2. In the second embodiment, the operating value of the transmission object to be transmitted is limited when transmitting the outdoor unit operating value, which is an operating value obtained in the outdoor unit 1B, to the indoor unit 2. This allows a reduction in the amount of data transmitted between the indoor unit 2 and the outdoor unit 1B and therefore allows a reduction in the impact on the transmission and reception of data for use in controlling the air conditioning system 10B, even if there is an increase in the number of data elements to be used for operational management. Third embodiment.

[0039] Fig. Figure 8 is a diagram showing a configuration of an air conditioner 10C according to a third embodiment. The air conditioner 10C comprises an outdoor unit 1, an indoor unit 2C, and a threshold setting unit 3. In the third embodiment, the air conditioner 10C, in addition to the functions of the first embodiment, has a function configured to externally set a value of the first threshold using the threshold setting unit 3. Components that are identical or similar to corresponding components of the air conditioner 10A according to the first embodiment are designated by identical reference numerals, and their detailed descriptions are omitted. The following description will mainly describe differences from the first embodiment.

[0040] The threshold setting unit 3, for which a remote control is an example in this case, outputs a set value of the first threshold to the indoor unit determination unit 21C of indoor unit 2C. Using the first threshold value output by threshold setting unit 3, indoor unit determination unit 21C determines whether an operating value is a transmission object to be transmitted. It should be noted that threshold setting unit 3 is not limited to a remote control, but can be a storage medium that stores a first threshold value, or a communication device that outputs a first threshold value received via a network, such as a cloud, to indoor unit 2C.The ability to change the value of the first threshold through the threshold setting unit 3 allows a user to change the value of the first threshold according to a variation of an operating value, which varies depending on a factor such as an hourly interval, the season, or an indoor environment property.

[0041] It should be noted that the above description refers to the case in which the threshold setting unit 3 sets a value of the first threshold for use in determining whether an operating value is a transmission object to be transferred from the indoor unit 2C to the outdoor unit 1; however, the threshold setting unit 3 can, for example, be used to configure the in Fig. The air conditioner 10B shown in Figure 7 is added to allow an external setting of the first threshold value. This value is used to determine whether an operating value is a transmission object to be transferred from the outdoor unit 1B to the indoor unit 2, in addition to the first threshold value used to determine whether an operating value is a transmission object to be transferred from the indoor unit 2 to the outdoor unit 1B. In this case, the threshold setting unit 3 can be configured to output a first threshold setting value directly to the outdoor unit 1B, or, if the threshold setting unit 3 is a remote control capable of communicating with the indoor unit 2, it can inform the outdoor unit 1B of a first threshold value via the indoor unit 2's communication unit 22, which is compatible with the outdoor unit.This enables the outdoor unit determination unit 13 to determine, using the provided value of the first threshold, whether an operating value is a transferable transfer object.

[0042] As described above, the air conditioner 10C according to the third embodiment can also achieve the same effect as the air conditioner 10A according to the first embodiment. In addition to the components of the air conditioner 10A, the air conditioner 10C further includes the threshold setting unit 3, which receives an input of a first threshold value to be used by the indoor unit determination unit 21C, which is a determination unit. This allows the value of the first threshold to be set from outside the air conditioner 10C for use in determining whether an operating value is a transmission object to be transmitted. This then allows a user to change the value of the first threshold according to a variation of an operating value, which varies depending on a factor such as the time of day, the season, or an indoor environmental characteristic. Fourth embodiment.

[0043] Fig. Figure 9 is a diagram showing a configuration of an air conditioner 10D according to a fourth embodiment. The air conditioner 10D comprises the outdoor unit 1 and an indoor unit 2D. The indoor unit 2D is connectable to a Cloud 4. Components that are identical or similar to corresponding components of the air conditioner 10A according to the first embodiment are designated by identical reference numerals, and their detailed descriptions are omitted. The following description mainly describes differences from the first embodiment.

[0044] The indoor unit 2D comprises, in addition to the components of the indoor unit 2 according to the first embodiment, a cloud-compatible transmission unit 24, which transmits an operating value to the cloud 4. It should be noted that the cloud 4 is an example of an external device outside the air conditioner 10D, and the cloud-compatible transmission unit 24 is an example of an external transmission unit that transmits an operating value to the external device.

[0045] The cloud-compatible transmission unit 24 transmits the indoor unit operating value obtained by the indoor unit operating value reference unit 23 to Cloud 4. During this operation, the cloud-compatible transmission unit 24 calculates a difference between a previous indoor unit operating value, which is the indoor unit operating value that was previously transmitted to Cloud 4, and a current indoor unit operating value, which is the last indoor unit operating value, and determines, based on the calculated difference, whether the current indoor unit operating value should be transmitted to Cloud 4.In particular, the cloud-matching transmission unit 24 transmits the current indoor unit operating value to cloud 4 if the difference between the current indoor unit operating value and the previous indoor unit operating value is greater than or equal to a second threshold, and does not transmit the current indoor unit operating value to cloud 4 if the difference is less than the second threshold.

[0046] The second threshold is determined in such a way that it does not affect fault diagnosis or a determination concerning inspection elements when Cloud 4 is informed about a respective operating value.

[0047] Fig. Figure 10 is a flowchart describing a procedure for transferring an operational value to Cloud 4, which is described in Fig. The process shown in Figure 9 is carried out on the indoor unit 2D. First, the cloud-compatible transmission unit 24 receives an indoor unit operating value from the indoor unit operating value reference unit 23 (step S31). The indoor unit operating value obtained in this step corresponds to the current indoor unit operating value. The cloud-compatible transmission unit 24 calculates a difference between a previous indoor unit operating value, which is stored, and the current indoor unit operating value obtained in step S31 (step S32).

[0048] The cloud-matching transmission unit 24 determines whether the difference calculated in step S32 is greater than or equal to a second threshold (step S33). If the difference is greater than or equal to the second threshold (step S33: Yes), the cloud-matching transmission unit 24 transmits the current indoor unit operating value to Cloud 4 (step S34). Additionally, the cloud-matching transmission unit 24 stores the current indoor unit operating value that was transmitted (step S35). The indoor unit operating value stored in this step is used as the previous indoor unit operating value in the next execution cycle of the [unclear text]. Fig. The procedure shown in step 10 is used. However, if the difference calculated in step S32 is less than the second threshold (step S33: No), the operations of steps S34 and S35 are skipped, and the procedure for transferring data ends. Fig. 10.

[0049] It should be noted that the in Fig. The transfer procedure shown in 10 is performed, for example, every time the indoor unit operating value reference unit 23 receives an indoor unit operating value. Furthermore, if multiple types of operating values ​​are received, the procedure shown in Fig. The procedure shown in section 10 for transferring operating values ​​is carried out for each type. This means that the difference between a previous indoor unit operating value and a current indoor unit operating value is calculated for each type of operating value, and a determination is made as to whether the operating value should be transferred to Cloud 4 for each type of operating value.

[0050] As described above, the air conditioner 10D according to the fourth embodiment can also achieve the same effect as the air conditioner 10A according to the first embodiment. Furthermore, the air conditioner 10D also includes the cloud-compatible transmission unit 24, which is an external transmission unit that determines, based on the difference between the current operating value and the previous operating value, whether the current operating value should be transmitted to the cloud 4, which is an external device.Specifically, the cloud-compatible transmission unit 24 transmits the current indoor unit operating value to Cloud 4 if the difference between the current indoor unit operating value and the previous indoor unit operating value is greater than or equal to a second threshold, and does not transmit the current indoor unit operating value to the cloud if the difference between the current indoor unit operating value and the previous indoor unit operating value is less than the second threshold. This can also reduce the amount of communication with Cloud 4.

[0051] It should be noted that the fourth embodiment described has the following function: the cloud-compatible transmission unit 24 has the function of transmitting an indoor unit operating value to the cloud 4. However, if the outdoor unit 1 has a function of receiving an outdoor unit operating value, the cloud-compatible transmission unit 24 can transmit an outdoor unit operating value received by the indoor unit 2D from the outdoor unit 1 to the cloud 4. In this case, the cloud-compatible transmission unit 24 is configured to determine, based on whether the difference is greater than or equal to the second threshold, for each type of outdoor unit operating value, whether an outdoor unit operating value is to be transmitted to the cloud 4. Fifth embodiment.

[0052] Fig. Figure 11 is a diagram showing a configuration of an air conditioner 10E according to a fifth embodiment. The air conditioner 10E comprises an outdoor unit 1E, an indoor unit 2E, and a transmission duration setting unit 5. In the fifth embodiment, a transmission duration is set, which is the duration for transmitting an operating value, and no operating value is transmitted during periods outside the transmission duration. It should be noted that the following description provides an example in which the transmission duration is set for an outdoor unit operating value.

[0053] The transmission duration setting unit 5 has a function for setting a transmission duration, for example, by using a remote control, a storage medium, or the like, or by transmitting data representing a transmission duration over a network, such as the cloud 4. The transmission duration setting unit 5 outputs transmission duration information, representing the set transmission duration, to an indoor unit determination unit 21E. In addition to performing the functions of the indoor unit determination unit 21, the indoor unit determination unit 21E informs the outdoor unit 1E about the transmission duration information output by the transmission duration setting unit 5 via the communication unit 22 corresponding to the outdoor unit.It should be noted that although the transmission duration setting unit 5 has been described as having the function to communicate with the indoor unit 2E and output transmission duration information to the indoor unit 2E, the transmission duration setting unit 5 may be configured to output the transmission duration information directly to the outdoor unit 1E.

[0054] The outdoor unit 1E comprises the calculation unit 11, the communication unit 12 matching the indoor unit, an outdoor unit determination unit 13E, and the outdoor unit operating value reference unit 14. The outdoor unit operating value reference unit 14 receives an outdoor unit operating value and outputs the received outdoor unit operating value to the outdoor unit determination unit 13E.

[0055] The outdoor unit determination unit 13E receives the transmission duration information via the indoor unit 2E, which represents the transmission duration set by the transmission duration setting unit 5, and determines, using the received transmission duration information, whether an outdoor unit operating value is a transmission object to be transmitted to the indoor unit 2E.In particular, if the time of the outdoor unit's acquisition of the operating value is within the transmission period, the outdoor unit determination unit 13E determines that the current outdoor unit's operating value is a transmission object to be transmitted and transmits the current outdoor unit's operating value to the indoor unit 2E using the communication unit 12 matching the indoor unit, whereas if the time of the outdoor unit's acquisition of the operating value is outside the transmission period, the outdoor unit determination unit 13E determines that the current outdoor unit's operating value is not a transmission object to be transmitted and does not transmit the current outdoor unit's operating value to the indoor unit 2E.

[0056] The indoor unit determination unit 21E of the indoor unit 2E has, in addition to the functions of the indoor unit determination unit 21, a function for informing the outdoor unit 1E about the transmission duration information, which is output by the transmission duration setting unit 5, and a function for outputting the outdoor unit operating value received by the outdoor unit 1E via the outdoor unit-compatible communication unit 22 to the cloud-compatible transmission unit 24E, as described above. Furthermore, the cloud-compatible transmission unit 24E has, in addition to the functions of the cloud-compatible transmission unit 24, a function for transmitting the outdoor unit operating value to the cloud 4.Although the Cloud-Matching Transmission Unit 24E, like the Cloud-Matching Transmission Unit 24, can determine whether an operating value is to be transferred to Cloud 4 using the difference between the previous and second thresholds for all the input operating values, it should be noted that it is assumed here that the Cloud-Matching Transmission Unit 24E processes indoor unit operating values ​​in the same way as the Cloud-Matching Transmission Unit 24 and processes outdoor unit operating values ​​in such a way that all the outdoor unit operating values ​​for which the Outdoor Unit Determination Unit 13E has determined that they are a transferable transmission object are transferred to Cloud 4.

[0057] It should be noted that setting a transmission period, for example for an operational value whose importance level varies with the season (e.g., data on the use of a de-icing control system) and / or for an operational value whose importance level varies depending on the reference time (e.g., data on the control system's use for restful sleep), allows a user to freely modify the timeframe for collecting operational values ​​as desired. For example, the transmission period can be set over several months (e.g., from December to March) or in hours (e.g., from 10:00 PM to 7:00 AM daily).

[0058] Fig. Figure 12 is a flowchart describing a procedure for transferring an outdoor unit operating value to Cloud 4, which is located in the Fig. The process is carried out on the air conditioning unit 10E shown in Figure 11. The outdoor unit operating value reference unit 14 receives an outdoor unit operating value (step S41). The outdoor unit operating value obtained in this step corresponds to the current outdoor unit operating value. Upon receiving the current outdoor unit operating value, which is obtained by the outdoor unit operating value reference unit 14, the outdoor unit determination unit 13E determines whether the time of obtaining the current outdoor unit operating value is within the transmission period (step S42).

[0059] If the time of acquisition of the current outdoor unit operating value is within the transmission period (step S42: Yes), the outdoor unit determination unit 13E determines that the current outdoor unit operating value is a transmission object to be transmitted and transmits the current outdoor unit operating value to the indoor unit 2E (step S43). Upon receipt of the outdoor unit operating value via the outdoor unit-matching communication unit 22 and the indoor unit determination unit 21E, the cloud-matching transmission unit 24E transmits the outdoor unit operating value received from outdoor unit 1E to Cloud 4 (step S44). If the time of acquisition of the current outdoor unit operating value is outside the transmission period (step S42: No), the operations of steps S43 and S44 are skipped, and the outdoor unit operating value is not transmitted to Cloud 4. The procedure of Fig. 12 therefore ends.

[0060] As described above, the air conditioning unit 10E according to the fifth embodiment can also achieve the same effect as the air conditioning unit 10A according to the first embodiment. Furthermore, the air conditioning unit 10E according to the fifth embodiment also includes the transmission duration setting unit 5, which receives an input of a time period for collecting an operating value. If several types of operating values ​​are received, the transmission duration setting unit 5 is configured to receive an input of the time period for collecting the operating value for each type of operating value to be collected.If the time of reference of the outdoor unit operating value is outside the transmission period set by the transmission period setting unit 5, the outdoor unit determination unit 13E, which is a determination unit, determines, regardless of the size of the difference between the comparison reference value and the current outdoor unit operating value, that the outdoor unit operating value is not a transmission object to be transmitted.Although the outdoor unit determination unit 13E is described herein as determining that, regardless of the size of the difference between the comparison reference value and the current outdoor unit operating value, the current outdoor unit operating value is a transfer object to be transferred if the time of the outdoor unit operating value's acquisition is within the transfer period, it should be noted that the outdoor unit determination unit 13E can determine whether the current outdoor unit operating value is a transfer object to be transferred based on the difference between the comparison reference value and the current outdoor unit operating value if the time of the outdoor unit operating value's acquisition is within the transfer period.

[0061] Furthermore, the air conditioner 10E includes the cloud-compatible transmission unit 24E, which is an external transmission unit that outputs the outdoor unit operating value to Cloud 4, which is an external device. This value is determined by the outdoor unit determination unit 13E, which is a determination unit, as a transmission object to be transmitted based on the transmission duration information. This can limit the outdoor unit operating values ​​to be transmitted to Cloud 4 to those obtained within the transmission duration and can therefore reduce the amount of communication with Cloud 4.

[0062] Although the transmission duration setting unit 5 is described herein as setting a transmission duration for outdoor unit operating values ​​obtained by the outdoor unit 1E, it should be noted that the transmission duration setting unit 5 is also configured to set a transmission duration equally for the indoor unit operating values ​​obtained by the indoor unit 2E. Sixth embodiment.

[0063] Fig. Figure 13 is a diagram showing a configuration of an air conditioner 10F according to a sixth embodiment. The air conditioner 10F is configured such that a single outdoor unit 1F is connected to several indoor units 2F, 2-1, 2-2, and 2-3. The indoor unit 2F is connected to the Cloud 4. The air conditioner 10F aggregates the indoor unit operating values ​​obtained by the indoor units 2F, 2-1, 2-2, and 2-3, initially in the outdoor unit 1F, and transmits an aggregated set of operating values, which is a set of the operating values ​​aggregated in the outdoor unit 1F, from the outdoor unit 1F via the indoor unit 2F to the Cloud 4.

[0064] Fig. 14 is a sequence diagram for describing a business that is in Fig. In Figure 13, air conditioning unit 10F is shown. First, indoor units 2F, 2-1, 2-2, and 2-3 each transmit an operating value to outdoor unit 1F (step S101). Outdoor unit 1F determines a comparison reference value based on the received operating values ​​(step S102). Outdoor unit 1F transmits the determined comparison reference value to each of the indoor units 2F, 2-1, 2-2, and 2-3 (step S103). Using the received comparison reference value, indoor units 2F, 2-1, 2-2, and 2-3 each determine whether the current operating value is a transferable object and, if determined to be a transferable object, transmit the operating value to outdoor unit 1F (step S104). The outdoor unit 1F aggregates the operating values ​​(step S105) and transfers an aggregated set of generated operating values ​​to the indoor unit 2F (step S106).The indoor unit 2F transmits the aggregated set of operating values ​​to Cloud 4 (step S107).

[0065] It should be noted that the operation of the determination described in the preceding first and other embodiments, using the comparison reference value and the first threshold value, to determine whether an operating value is a transfer object to be transferred, can be carried out, for example, on the operating values ​​transferred in step S104 or on the aggregated set of operating values ​​transferred from the outdoor unit 1F to the indoor unit 2F in step S106.

[0066] Fig. Figure 15 is a diagram showing a detailed configuration of the air conditioner 10F according to the sixth embodiment. It should be noted that Fig. 15 the outdoor unit 1F and the indoor unit 2F of the in Fig. The air conditioning unit 10F shown in Figure 13 is shown and the indoor units 2-1 to 2-3 are omitted because the indoor units 2-1 to 2-3 are the same as the indoor unit 2 according to the first embodiment.

[0067] The outdoor unit 1F comprises the calculation unit 11B, the indoor unit-compatible communication unit 12, an outdoor unit determination unit 13F, and the outdoor unit operating value reference unit 14. The calculation unit 11B calculates the comparison reference value for the indoor unit operating value and the outdoor unit operating value. The calculation unit 11B transmits the comparison reference value calculated for the indoor unit operating value to the indoor unit 2F using the indoor unit-compatible communication unit 12 and outputs the comparison reference value calculated for the outdoor unit operating value to the outdoor unit determination unit 13F.

[0068] The outdoor unit determination unit 13F comprises an aggregation unit 131, which aggregates the operating values ​​received from the multiple indoor units 2F, 2-1, 2-2, and 2-3 and generates an aggregated set of operating values. The outdoor unit determination unit 13F is configured to generate an aggregated set of operating values ​​based on the indoor unit operating values ​​received from the indoor units 2F, 2-1, 2-2, and 2-3 and based on the outdoor unit operating value obtained by the outdoor unit operating value reference unit 14. The outdoor unit determination unit 13F transmits the aggregated set of operating values ​​generated by the aggregation unit 131 to the indoor unit 2F using the indoor unit-compatible communication unit 12.

[0069] Upon receiving the aggregated set of operating values ​​from the outdoor unit 1F, an indoor unit determination unit 21F of the indoor unit 2F outputs the received aggregated set of operating values ​​to the cloud-compatible transmission unit 24. The cloud-compatible transmission unit 24 transmits the input aggregated set of operating values ​​to Cloud 4. The cloud-compatible transmission unit 24 is configured to transmit all operating values ​​in the input aggregated set of operating values ​​to Cloud 4. Because the indoor unit operating values ​​to be transmitted to the outdoor unit 1F are limited in the indoor unit determination unit 21F, the indoor unit operating values ​​transmitted to Cloud 4 are a subset of the indoor unit operating values ​​obtained by the indoor unit operating value reference unit 23, even if the cloud-compatible transmission unit 24 transmits all operating values ​​to Cloud 4.This can reduce the amount of communication with Cloud 4. Furthermore, limiting the operating values ​​to be transmitted from the outdoor unit 1F to the indoor unit 2F in the outdoor unit determination unit 13F can reduce the amount of communication with Cloud 4, even if the cloud-matching transmission unit 24 transmits all the operating values ​​to Cloud 4.

[0070] Furthermore, the cloud-compatible transmission unit 24 can limit the operating values ​​transmitted to Cloud 4 using the previous operating value and the second threshold, as described in the fourth embodiment. In this case, the amount of communication with Cloud 4 can be further reduced.

[0071] Next, a hardware configuration for implementing the functions of each of the air conditioners 10A to 10F according to the first to sixth embodiments is described. The functions of the computation units 11 and 11B, the outdoor unit determination units 13, 13E, and 13F, the outdoor unit operating value reference unit 14, the indoor unit determination units 21, 21C, 21E, and 21F, the indoor unit operating value reference unit 23, and the cloud-compatible transmission units 24 and 24E are implemented by processing circuits. These processing circuits can each be implemented in a dedicated hardware element or in a control circuit using a central processing unit (CPU).

[0072] If the preceding processing circuits are each implemented in a dedicated hardware element, then each of these is implemented in a processing circuit 90, which is located in Fig. 16 is shown. Fig. Figure 16 is a diagram showing a dedicated hardware element for implementing the functions of each of the air conditioners 10A to 10F according to the first to sixth embodiments. The processing circuit 90 is a single circuit, a set of multiple circuits, a programmed processor, a parallel programmed processor, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a combination thereof.

[0073] If the preceding processing circuits are each implemented by a control circuit using a CPU, this control circuit is, for example, a control circuit 91, which, as in Fig. 17 is shown configured. Fig. Figure 17 is a diagram showing a configuration of the control circuit 91 for implementing the functions of each of the air conditioners 10A to 10F according to the first to sixth embodiments. As shown in Fig.As shown in Figure 17, the control circuit 91 comprises a processor 92 and a memory 93. The processor 92 is a CPU, which is also referred to as a processing unit, arithmetic unit, a microprocessor, a microcomputer, a digital signal processor (DSP), and the like. The memory 93 is, for example, a non-volatile or volatile semiconductor memory, such as random-access memory (RAM), read-only memory (ROM), flash memory, erasable programmable ROM (EPROM), or electrically erasable programmable ROM (EEPROM) (registered trademark); a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, a digital universal disc (DVD), or the like.

[0074] If the preceding processing circuits are each implemented by the control circuit 91, the functions are provided in such a way that the processor 92 reads and executes a program corresponding to the processing of a respective component and stored in the memory 93. In addition, the memory 93 is also used as temporary storage during processing performed by the processor 92. The program to be executed by the processor 92 can be provided using a storage medium that stores the program or via a communication channel, such as the internet.

[0075] The configurations described in the preceding embodiments are merely examples. These configurations can be combined with other known technologies, and configurations from different embodiments can be combined with one another. Furthermore, such configurations can be partially omitted and / or modified without deviating from the core idea.

[0076] Although the above fourth to seventh embodiments were described as containing the cloud-compatible transmission units 24 and 24E in the indoor units 2C, 2D, 2E and 2F, for example a communication device which is separate from the indoor units 2C, 2D, 2E and 2F may have the functions of one of the cloud-compatible transmission units 24 and 24E.
