[0002] Conventionally, there have been chilled / hot water type air conditioning systems that perform heating and cooling by exchanging heat between hot water or cold water and air.

[0003] JP 2013-181730 A

[0004] In conventional chilled and hot water air conditioning systems, the temperature of the chilled and hot water used for heat exchange is set to a constant value, which can lead to excessive comfort levels that exceed the range of comfort felt by the user of the air conditioning system, resulting in the consumption of more electricity than necessary.

[0005] The present disclosure is based on the inventor's findings and provides a temperature adjustment system, a control information prediction method, and a control information prediction program that can predict in advance an excessively comfortable state that will occur in the future and change control information before the excessively comfortable state occurs.

[0006] One temperature adjustment system disclosed herein is a temperature adjustment system comprising: a first heat exchanger that performs heat exchange between outside air and a heat medium; a second heat exchanger that performs heat exchange between the heat medium and a first fluid; a third heat exchanger that performs heat exchange between the first fluid and a second fluid; a pump that circulates the first fluid between the second heat exchanger and the third heat exchanger; and a control device, wherein the control device comprises: an equipment information acquisition unit that acquires equipment information that is information related to at least one of the temperature and flow rate of the first fluid exiting the second heat exchanger; an air temperature information acquisition unit that acquires outside air temperature information that indicates the outside air temperature; and a control prediction unit that predicts control information of the temperature adjustment system for a future second period based on the equipment information and air temperature information acquired in a first period.

[0008] A control information prediction program, which is one aspect of the present disclosure, is a control information prediction method used in a temperature adjustment system including a first heat exchanger that performs heat exchange between outside air and a heat medium, a second heat exchanger that performs heat exchange between the heat medium and a first fluid, a third heat exchanger that performs heat exchange between the first fluid and a second fluid, a pump that circulates the first fluid between the second heat exchanger and the third heat exchanger, and a control device, and causes a processor to execute the control information prediction method, which acquires equipment information that is information related to at least one of the temperature and flow rate of the first fluid exiting the second heat exchanger, acquires outside air temperature information that indicates the outside air temperature, and predicts control information of the temperature adjustment system for a future second period based on the equipment information and air temperature information acquired in a first period.

[0009] According to the present disclosure, it is possible to contribute to energy conservation by predicting the occurrence of an excessively comfortable state and predicting control information that will avoid that state.

Fig. 3 is a flowchart showing an example of a decision flow when a temperature control unit controls the temperature adjustment system based on predicted control information.

[0011] Hereinafter, embodiments of a temperature control system, a control information prediction method, and a control information prediction program according to the present disclosure will be described with reference to the drawings. Note that the following embodiments are presented as examples to explain the present disclosure and are not intended to limit the present disclosure. For example, the shapes, structures, materials, components, relative positional relationships, connection states, numerical values, mathematical formulas, the content of each step in a method, and the order of each step shown in the following embodiments are merely examples and may include content not described below. Furthermore, while geometric expressions such as parallel and orthogonal may be used, these expressions do not imply mathematical precision and include substantially acceptable errors, deviations, and the like. Furthermore, expressions such as simultaneous and identical also include substantially acceptable ranges.

[0012] The drawings are schematic diagrams in which emphasis, omission, or adjustment of proportions has been appropriately made to explain the present disclosure, and differ from the actual shapes, positional relationships, and proportions. The X-axis, Y-axis, and Z-axis shown in the drawings represent Cartesian coordinates arbitrarily set for the purpose of illustrating the drawings. In other words, the Z-axis is not necessarily an axis along the vertical direction, and the X-axis and Y-axis are not necessarily located within a horizontal plane.

[0013] In addition, multiple inventions may be collectively described below as one embodiment, and some of the content described below may be described as optional components related to the present disclosure.

[0014] 1 is a diagram showing the circuit configuration of a temperature adjustment system 100. The temperature adjustment system 100 is a device that adjusts the temperature of a second fluid by performing heat exchange between outside air and a heat medium, heat exchange between the heat medium and a first fluid, and heat exchange between the first fluid and a second fluid, thereby heating or cooling the second fluid, and includes a heat pump 111, a fluid device 112, and a control device 130.

[0015] The heat pump 111 is a mechanical heat transfer device that includes a first heat exchanger 113, a compressor 114, a second heat exchanger 115, an expansion valve 116, and a heat medium (refrigerant) filled in a first pipe 117 that connects these components in a ring shape. Note that Fig. 1 shows the temperature adjustment system 100 in a heating mode that heats a first fluid flowing through a fluid device 112.

[0016] In the first heat exchanger 113, heat is exchanged between the heat medium in the first piping 117 and the outside air circulating within the first heat exchanger 113. In the present embodiment, outside air blown by the fan 103 flows into the first heat exchanger 113, and heat is exchanged between the outside air and the heat medium. When the heat pump 111 is in the heating mode, a heat medium that is colder than the outside air temperature flows into the first heat exchanger 113, and the heat medium absorbs heat from the outside air. In other words, the first piping 117 in the first heat exchanger 113 functions as an evaporator. On the other hand, when the heat pump 111 is in the cooling mode, a heat medium that is hotter than the outside air temperature flows into the first heat exchanger 113, and the heat medium dissipates heat to the outside air. In other words, the first piping 117 in the first heat exchanger 113 functions as a condenser.

[0017] The compressor 114 compresses the heat medium in the first pipe 117 to increase the temperature of the heat medium. When the heat pump 111 is in the heating mode, the compressor 114 further compresses and heats the heat medium whose temperature has increased by removing heat from the outside air in the first heat exchanger 113. On the other hand, when the heat pump 111 is in the cooling mode, the compressor 114 further compresses and heats the heat medium whose temperature has increased by removing heat from the fluid in the second heat exchanger 115. The direction of the heat medium flowing into and out of the compressor 114 is changed by a four-way valve 118.

[0018] The second heat exchanger 115 exchanges heat between the heat medium in the first pipe 117 and the first fluid in the fluid device 112. When the heat pump 111 is in heating mode, the heat medium heated by the compressor 114 flows into the second heat exchanger 115 and heats the first fluid in the fluid device 112. In other words, the first pipe 117 in the second heat exchanger 115 functions as a condenser. On the other hand, when the heat pump 111 is in cooling mode, the heat medium that is colder than the first fluid in the fluid device 112 flows into the second heat exchanger 115 and cools the fluid in the fluid device 112. In other words, the first pipe 117 in the second heat exchanger 115 functions as an evaporator.

[0019] The expansion valve 116 suddenly reduces the pressure of the heat medium in the first pipe 117, thereby lowering its temperature. When the heat pump 111 is in the heating mode, the expansion valve 116 suddenly reduces the pressure of the heat medium that has been cooled in the second heat exchanger 115 and flowed in, thereby further lowering its temperature. On the other hand, when the heat pump 111 is in the cooling mode, the expansion valve 116 suddenly reduces the pressure of the heat medium that has been cooled in the first heat exchanger 113 and flowed in, thereby further lowering its temperature.

[0020] As described above, the heat pump 111 according to this embodiment exchanges heat between the outside air and the first fluid in the fluid device 112 via the heat medium in the first pipe 117 .

[0021] In this embodiment, the heat pump 111 includes an outside air temperature sensor 216. The type of the outside air temperature sensor 216 is not limited, but may be, for example, a thermistor.

[0022] The fluid device 112 is a device that circulates a first fluid, which is heat exchanged between the heat medium of the heat pump 111 and the second heat exchanger 115, through the second heat exchanger 115 and the third heat exchanger 119. The type of fluid device 112 is not limited, but in this embodiment, the fluid device 112 circulates water (first fluid) that is heated or cooled in the second heat exchanger 115 using piping, and adjusts the temperature of the indoor air (second fluid) by performing heat exchange between the water and the indoor air (second fluid) in the room (building) using the third heat exchanger 119. The fluid device 112 includes the third heat exchanger 119, a second piping 120, a pump 121, and an outlet sensor 214. In this embodiment, the fluid device 112 includes an inlet sensor 215.

[0023] In the third heat exchanger 119, heat is exchanged between the first fluid in the second pipe 120 and the second fluid circulating within the third heat exchanger 119. The fluid circulating within the third heat exchanger 119 is not limited to any particular type. For example, hot water used for bathing, hand washing, dish washing, etc. can be used. In the present embodiment, the room air blown by the fan 217 flows into the third heat exchanger 119, and heat is exchanged between the water circulating through the second pipe 120, etc. by the pump 121 and the room air, thereby cooling or heating the room.

[0024] The outlet sensor 214 is a sensor that senses at least one of the temperature and flow rate of the first fluid exiting the second heat exchanger 115. The outlet sensor 214 is disposed near the fluid outlet of the second heat exchanger 115.

[0025] The inlet sensor 215 is a sensor that senses at least one of the temperature and flow rate of the first fluid returning from the third heat exchanger 119 to the second heat exchanger 115. The inlet sensor 215 is disposed near the fluid inlet of the second heat exchanger 115.

[0026] 2 is a block diagram showing the functional configuration of the control device 130. The control device 130 is a device that controls the temperature adjustment system 100 and includes a processor. The control device 130 realizes, as processing units, an equipment information acquisition unit 131, a temperature information acquisition unit 132, and a control prediction unit 133 by having the processor execute a control information prediction program. In the present embodiment, the control device 130 includes a storage device 134 and a temperature control unit 135.

[0027] The device information acquisition unit 131 is a processing unit that acquires device information, which is information related to at least one of the temperature of the first fluid flowing from the second heat exchanger 115 toward the third heat exchanger 119 and the flow rate of the first fluid. In the present embodiment, the outlet sensor 214 and the inlet sensor 215 are temperature sensors. The device information acquisition unit 131 acquires the temperature of the first fluid flowing from the second heat exchanger 115 toward the third heat exchanger 119 from the outlet sensor 214, acquires the temperature of the first fluid returning from the third heat exchanger 119 to the second heat exchanger 115 from the inlet sensor 215, and acquires information indicating the difference between these temperatures as device information.

[0028] Note that the device information acquisition unit 131 may acquire device information, such as the temperature and flow rate of the first fluid, directly from a sensor, or may acquire device information from the pump 121. For example, device information related to at least one of the temperature and flow rate of the first fluid flowing from the second heat exchanger 115 to the third heat exchanger 119 may be acquired from the output of the pump 121, the rotation speed of the motor included in the pump 121, the control value of a drive control device that controls the drive of the motor included in the pump 121, etc. The information related to the output of the pump 121 is device information indicating the temperature difference and flow rate difference of the first fluid.

[0029] The temperature information acquisition unit 132 is a processing unit that acquires outside temperature information indicating the temperature of the outside air. The source from which the outside temperature information is acquired is not limited, and for example, the outside temperature information may be acquired via a network such as the Internet. In this embodiment, the temperature information acquisition unit 132 acquires the outside temperature information from an outside temperature sensor 216 provided in the heat pump 111.

[0030] The control prediction unit 133 is a processing unit that predicts air conditioner control information for a future second period based on device information acquired multiple times during a past first period and temperature information acquired multiple times during the past first period. The length of the first period is not limited, but may be a predetermined period such as one day, one week, or one month. The first period may be longer than the second period. The first period may also be a positive integer multiple of the second period. The length of the second period is not limited, but may be, for example, a period during which the temperature adjustment system 100 is continuously controlled using the predicted control information. In this embodiment, one day is used as the second period.

[0031] The control prediction unit 133 acquires from the storage device 134 the device information acquired by the device information acquisition unit 131 during the period from a date going back a first period from the present to a date including the present and stored in the storage device 134, and the temperature information acquired by the temperature information acquisition unit 132 during the period from a date going back a first period from the present to a date including the present and stored in the storage device 134, and predicts the control information for at least the day after the date including the present.

[0032] The prediction method of the control prediction unit 133 is not limited. In the present embodiment, the control prediction unit 133 includes a model trained using prediction information that predicts device information, temperature information, and outdoor air temperature, and predicts the control information of the air conditioner for the second time period using the model. The model is a model used as so-called artificial intelligence, and in the present embodiment, the control prediction unit 133 includes a trained model trained by another device. The results predicted by the control prediction unit 133 are not limited. For example, examples of control information include the temperature of the first fluid flowing from the second heat exchanger 115 to the third heat exchanger 119, the flow rate of the first fluid flowing from the second heat exchanger 115 to the third heat exchanger 119, the relationship between outdoor air temperature information and the temperature of the first fluid flowing from the second heat exchanger 115 to the third heat exchanger 119, and the output of the pump 121.

[0033] 3 is a flowchart showing an example of a judgment flow when the temperature control unit 135 controls the temperature adjustment system 100 based on predicted control information. The processing flow shown in FIG. 3 is a flow when the temperature adjustment system 100 heats the inside air using the third heat exchanger 119. The temperature control unit 135 is a processing unit that controls the heat pump 111 and the fluid device 112 based on the predicted control information. The temperature control unit 135 acquires the output of the pump 121 as control information from the control prediction unit 133 (S101). Next, it determines whether the acquired output of the pump 121 is lower than a predetermined output threshold (S102). If the acquired output of the pump 121 is lower than the output threshold (S102, Yes), the temperature control unit 135 determines that the day on which the temperature adjustment system 100 is controlled based on the predicted control information will be excessively comfortable (S103), and on the day corresponding to the predicted control information, switches the table that determines the temperature of the first fluid flowing from the second heat exchanger 115 to the third heat exchanger 119 to a table that determines a temperature one level lower than that of the previous day, and controls the temperature adjustment system 100 based on the switched table (S104).

[0034] On the other hand, if the acquired output of the pump 121 is not lower than the output threshold (S102, No), the temperature control unit 135 determines that the day on which the temperature adjustment system 100 is controlled based on the predicted control information will not result in excessive comfort (S105), and controls the temperature adjustment system 100 on the day corresponding to the predicted control information by maintaining the table for the previous day, which determines the temperature of the first fluid flowing from the second heat exchanger 115 toward the third heat exchanger 119 (S106). Here, the table is, for example, a table showing the relationship between the temperature of the first fluid flowing from the second heat exchanger 115 and air temperature information.

[0035] It should be noted that the present disclosure is not limited to the above-described embodiments. For example, the present disclosure may be embodied in another embodiment realized by any combination of the components described in this specification or by excluding some of the components. Furthermore, the present disclosure also includes modifications obtained by applying various modifications to the above-described embodiments that would occur to a person skilled in the art without departing from the spirit of the present disclosure, i.e., the meaning of the wording of the claims.

[0036] For example, the equipment information may be not only the difference between the temperature of the first fluid leaving the second heat exchanger 115 and the temperature of the first fluid returning to the second heat exchanger 115, but also the difference between the flow rate of the first fluid leaving the second heat exchanger 115 and the flow rate of the first fluid returning to the second heat exchanger 115. The equipment information may also be the output of the pump 121, etc.

[0037] Furthermore, as shown in FIG. 4 , a training device 140 may be provided that is connected via a network to multiple temperature control systems 100 installed in multiple locations, and the training device 140 may include a model learning unit 141 and a providing unit 142. The model learning unit 141 is a processing unit that trains a model for each region based on device information, temperature information, and forecast information for the region in which the control device 130 is installed, acquired from multiple control devices 130. The providing unit 142 provides the trained model to the control prediction unit 133 included in the control device 130 installed in each region. Note that the vector used by the model learning unit 141 is not limited to the above. For example, the vector may include weather information for each user based on the location information of each user of the temperature control system 100, rather than for each region.

[0038] Furthermore, although the temperature control unit 135 has been described as controlling the temperature adjustment system 100 using a table, it is also possible to change the constants of a two-dimensional graph showing the relationship between the outside air temperature and the output of the pump 121.

[0039] Furthermore, the control information may be only the temperature of the first fluid exiting the second heat exchanger 115 or only the flow rate of the first fluid, rather than the relationship between the outside air temperature information and the temperature of the first fluid exiting the second heat exchanger 115.

[0040] (Summary) The temperature adjustment system 100 of the first aspect is a temperature adjustment system 100 including a first heat exchanger 113 that exchanges heat between outside air and a heat medium, a second heat exchanger 115 that exchanges heat between the heat medium and a first fluid, a third heat exchanger 119 that exchanges heat between the first fluid and a second fluid, a pump 121 that circulates the first fluid between the second heat exchanger 115 and the third heat exchanger 119, and a control device 130, wherein the control device 130 includes an equipment information acquisition unit 131 that acquires equipment information that is information related to at least one of the temperature and flow rate of the first fluid exiting the second heat exchanger 115, an air temperature information acquisition unit 132 that acquires outside air temperature information that indicates the outside air temperature, and a control prediction unit 133 that predicts control information for the air conditioner in a future second time period based on the equipment information and air temperature information acquired in a first time period.

[0041] According to the first aspect, the control information can be determined by predicting the load on the third heat exchanger 119 without obtaining information on the second fluid with which the third heat exchanger 119 exchanges heat.
