[0001] The present disclosure relates to a thermal storage and release system. [Background technology]

[0002] 2. Description of the Related Art Conventionally, a heat storage and release system has been proposed in which waste heat from a factory or the like is stored in an adsorbent and released to any heat demand facility to supply the heat (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6673670 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned heat storage and release system, in the early stages of heat release from the adsorbent to the heat demand equipment, the amount of heat released from the adsorbent to the heat demand equipment reaches a maximum value, but thereafter, the amount of heat released gradually decreases over time.

[0005] For this reason, it is difficult to stably supply heat to the heat demanding equipment (i.e., the heat dissipation target) simply by dissipating heat from the adsorbent to the heat demanding equipment, and the temperature of the heat demanding equipment becomes unstable.

[0006] In view of the above, an object of the present disclosure is to provide a heat storage and release system that stably supplies heat to a heat release target. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a heat dissipation device comprising: a plurality of heat dissipation units (10) each having an adsorbent that adsorbs moisture contained in the air and dissipates heat; a blower (20b) that supplies air to some of the heat dissipation units among the plurality of heat dissipation units, and supplies air heated by heat dissipation from the adsorbent to a heat dissipation target (4), A switching unit (30, 40) is provided for switching a heat dissipation unit that dissipates heat into air supplied to a heat dissipation target among the plurality of heat dissipation units, The switching unit switches the heat dissipation unit that dissipates heat into the air supplied to the heat dissipation target so that the amount of heat dissipated to the heat dissipation target is equal to or greater than a required value.

[0008] Therefore, it is possible to provide a heat storage and release system that stably supplies heat to a heat release target.

[0009] In the invention described in claim 6, a heat dissipation unit (10) including an adsorbent (10a) that adsorbs moisture contained in the air and dissipates heat; a blower (20b) for supplying air to a portion of the heat dissipation unit, and the air heated by heat dissipation from the adsorbent is supplied to the heat dissipation target, a switching unit (30) for changing a part of an area of ​​the heat dissipation unit to which air is supplied by a blower; The switching unit displaces the partial area to which air is supplied by the blower so that the amount of heat dissipated to the heat dissipation target is equal to or greater than a required value.

[0010] Therefore, it is possible to provide a heat storage and release system that stably supplies heat to a heat release target.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, the same or equivalent parts are denoted by the same reference numerals in the drawings for the sake of simplicity of description.

[0013] (First embodiment) 1, 2, etc. show the overall configuration of a first embodiment of a heat storage and release system 1 of the present disclosure. As shown in FIG. 1, the heat storage and release system 1 of the present embodiment includes a heat storage site 3, a heat release site 5, and a plurality of heat release units 10.

[0014] Each of the heat dissipation units 10 includes an adsorbent. As described below, the heat dissipation units 10 are used to store heat discharged from the heat supply facility 2 and transport it offline to a heat demand facility (i.e., a heat dissipation target) 4. Note that, as the adsorbent in this embodiment, for example, a honeycomb-shaped adsorbent is used. As the adsorbent, for example, a polymer sorption agent, silica gel, zeolite, etc. are used.

[0015] The heat storage site 3 is a site used for storing heat discharged from the heat supply facility 2 in a plurality of heat dissipation units 10. The heat storage site 3 is provided with a heat storage tank 3A for storing heat in the plurality of heat dissipation units 10. The heat storage site 3 is provided with a blower 20a for generating an air flow passing through the plurality of heat dissipation units 10.

[0016] The blower 20a draws in high-temperature, low-humidity air from the heat supply facility 2 and blows the drawn-in high-temperature, low-humidity air to the multiple heat dissipation units 10 in the heat storage tank 3A.

[0017] In this embodiment, the temperature of the air sucked by the blower 20a from the heat supply facility 2 is, for example, 100° C. The relative humidity of the air sucked by the blower 20a from the heat supply facility 2 is, for example, 5% RH or less.

[0018] The heat dissipation units 10 store heat by desorbing (i.e., drying) the adsorbent with air blown out from the blower 20a (i.e., exhaust heat from the heat supply facility 2) and releasing moisture. Therefore, the heat dissipation units 10 discharge high-humidity air to the outside of the heat storage tank 3A as the adsorbent stores heat.

[0019] The plurality of heat dissipation units 10 that have stored heat in the heat storage tank 3A of the heat storage site 3 in this manner are transported into the heat dissipation tank 5A of the heat dissipation site 5 by the mobile body 6. As the mobile body 6 in this embodiment, a vehicle such as a truck is used.

[0020] The heat dissipation site 5 is a site that dissipates heat stored in multiple heat dissipation units 10 to a heat demand facility 4. The heat demand facility 4 is a facility that uses exhaust heat from a heat supply facility 2, such as a hot water pool, a hot spring, or a greenhouse cultivation facility.

[0021] The heat dissipation site 5 is provided with a fan 20b that generates an air flow that passes through the multiple heat dissipation units 10. The fan 20b draws in high humidity and low temperature air from the heat demand facility 4 and blows it out of each of the multiple heat dissipation units 10 in the heat dissipation tank 5A.

[0022] Accordingly, in each of the heat dissipation units 10, the adsorbent adsorbs moisture from the high humidity air from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the adsorbent. Therefore, the blower 20b blows out the air with heat dissipated from the adsorbent toward the heat demanding facility 4. In other words, the air heated by the heat dissipation from the adsorbents of the heat dissipation units 10 is supplied to the heat demanding facility 4.

[0023] In this embodiment, the temperature of the air sucked by the fan 20b from the heat demanding facility 4 is, for example, 30° C. The relative humidity of the air sucked by the fan 20b from the heat demanding facility 4 is, for example, 95 RH%.

[0024] The temperature of the air blown out by the fan 20b toward the heat demanding facility 4 is, for example, 45° C. The relative temperature of the air blown out by the fan 20b toward the heat demanding facility 4 is, for example, 50% RH.

[0025] Therefore, each of the heat dissipation units 10 supplies high-temperature, low-humidity air dissipated from the adsorbent to the heat demanding facility 4. Accordingly, the heat demanding facility 4 can utilize the heat supplied from the heat dissipation units 10.

[0026] Furthermore, the plurality of heat dissipation units 10 that have finished dissipating heat to the heat demand facility 4 are transported to the heat storage site 3 by the mobile body 6. Therefore, the transported plurality of heat dissipation units 10 store the heat discharged from the heat supply facility 2 in the same manner as described above.

[0027] In this manner, the multiple heat dissipation units 10 are transported by the mobile object 6 and travel back and forth between the heat storage site 3 and the heat dissipation site 5. In this manner, the multiple heat dissipation units 10 transport the heat discharged from the heat supply facility 2 to the heat demand facility 4.

[0028] Next, the operation of the heat dissipation site 5 in the heat dissipation tank 5A of this embodiment will be described with reference to FIGS. 2, 3, 4, 5, etc. FIG. 2 is a schematic diagram showing a schematic configuration inside the heat dissipation tank 5A, and FIG. 3 is a block diagram showing the electrical configuration of the heat storage and release system 1 inside the heat dissipation tank 5A.

[0029] As shown in FIG. 3, the thermal storage and release system 1 includes a transport device 30, a control device 40, an inlet temperature sensor 50a, an outlet temperature sensor 50b, an inlet air flow sensor 51a, an outlet air flow sensor 51b, an inlet humidity sensor 52a, and an outlet humidity sensor 52b.

[0030] The transport device 30 is disposed in the heat dissipation tank 5A of the heat dissipation site 5. The transport device 30 includes an electric motor and the like, and transports the plurality of heat dissipation units 10 transported from the heat storage site 3 by the moving body 6 one by one to the blowing destination of the blower 20b by driving the electric motor.

[0031] The inlet temperature sensor 50a is a temperature sensor that detects the temperature of air flowing into the inlet of the heat dissipation unit 10. The outlet temperature sensor 50b is a temperature sensor that detects the temperature of air discharged from the outlet of the heat dissipation unit 10.

[0032] The inlet air flow sensor 51a is an air flow sensor that detects the amount of air flowing into the inlet of the heat dissipation unit 10. The outlet air flow sensor 51b is an air flow sensor that detects the amount of air discharged from the outlet of the heat dissipation unit 10.

[0033] In the following description, the inlet temperature sensor 50a, the outlet temperature sensor 50b, the inlet air flow sensor 51a, and the outlet air flow sensor 51b will be collectively referred to as sensors 50a, 50b, 51a, and 51b.

[0034] The inlet humidity sensor 52a is a humidity sensor that detects the humidity of air flowing into the inlet of the heat dissipation unit 10. The outlet humidity sensor 52b is a humidity sensor that detects the humidity of air discharged from the outlet of the heat dissipation unit 10. The inlet humidity sensor 52a and the outlet humidity sensor 52b are used by the control device 40 to detect failures in the multiple heat dissipation units 10.

[0035] The control device 40 is configured with a microcomputer, a memory, etc., and configures a switching unit together with the transport device 30. The control device 40 controls the transport device 30 by executing a switching control process based on output signals from the sensors 50a, 50b, 51a, 51b, 52a, 52b, etc. The switching control process is a control process for transporting the multiple heat dissipation units 10 one by one to the blowing destination of the fan 20b by the transport device 30.

[0036] Hereinafter, the switching control process performed by the control device 40 of this embodiment will be described with reference to FIG. 4, FIG. 5, etc.

[0037] The control device 40 executes a switching control process according to the flowchart of Fig. 4. Fig. 4 is a flowchart showing the details of the switching control process.

[0038] First, in step S100, the control device 40 controls the transport device 30 to transport a first heat dissipation unit 10 among the plurality of heat dissipation units 10 to the blowing destination of the blower 20b.

[0039] Here, the fan 20b operates under the control of the control device 40. At this time, the fan 20b draws in high-humidity air from the heat demand facility 4 as indicated by the arrow Yc in FIG. 2 and blows out the drawn-in high-humidity air to the first heat dissipation unit 10.

[0040] In the first heat dissipation unit 10, the heat storage material absorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the heat storage material. Therefore, the first heat dissipation unit 10 supplies high-temperature, low-humidity air to the heat demand facility 4, as shown by Yd in FIG.

[0041] Next, in step S110, the control device 40 calculates the amount of heat dissipated Ha from the first heat dissipation unit 10 based on the output signals of the sensors 50a, 50b, 51a, 51b, and the like.

[0042] Next, in step S120, the control device 40 determines whether or not the amount of heat radiation Ha of the first heat radiation unit 10 is equal to or greater than a threshold value. The threshold value is set to a value greater than a required value.

[0043] At this time, the control device 40 determines YES in the above step S120 when the heat radiation amount Ha of the first heat radiation unit 10 is equal to or greater than the threshold value. Accordingly, the control device 40 executes the calculation process of the heat radiation amount Ha in step S110.

[0044] Therefore, the control device 40 repeats the calculation process of the heat dissipation amount Ha in step S110 and the determination process of the heat dissipation amount Ha in step S120 until the heat dissipation amount Ha falls below the threshold value and the result of the determination in step S120 is NO.

[0045] Thereafter, when the amount of heat dissipation Ha becomes less than the threshold value, the control device 40 determines NO in step S120.

[0046] Accordingly, in step S100, the control device 40 controls the transport device 30 to transport the second heat dissipation unit 10, instead of the first heat dissipation unit 10, to the blowing destination of the blower 20b.

[0047] As a result, the transport device 30 switches from the first heat dissipation unit 10 to the second heat dissipation unit 10 as the heat dissipation unit 10 for dissipating heat into the air supplied to the heat demanding facility 4 among the multiple heat dissipation units 10.

[0048] The second heat dissipation unit 10 is a heat dissipation unit 10 among the multiple heat dissipation units 10 excluding the first heat dissipation unit 10, and is a heat dissipation unit 10 that has not dissipated heat to the heat demanding facility 4. In other words, the second heat dissipation unit 10 is a heat dissipation unit 10 that is not being used to dissipate heat to the heat demanding facility 4.

[0049] At this time, the fan 20b draws in high humidity air from the heat demand facility 4 and blows the drawn in high humidity air to the second heat dissipation unit 10.

[0050] In the second heat dissipation unit 10, the heat storage material absorbs moisture in the high-humidity air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the heat storage material. Therefore, the second heat dissipation unit 10 supplies high-temperature, low-humidity air to the heat demanding facility 4.

[0051] Thereafter, the control device 40 repeats the calculation process of the heat dissipation amount Ha in step S110 and the determination process of the heat dissipation amount Ha in step S120 in the same manner as described above until the heat dissipation amount Ha of the second heat dissipation unit 10 becomes less than the threshold value.

[0052] Thereafter, in step S120, the control device 40 determines that the heat dissipation amount Ha of the second heat dissipation unit 10 is less than the threshold value and determines NO. Then, in step S100, the control device 40 controls the transport device 30 to transport the third heat dissipation unit 10 to the blowing destination of the blower 20b instead of the second heat dissipation unit 10.

[0053] As a result, the transport device 30 is controlled by the control device 40 to switch from the second heat dissipation unit 10 to the third heat dissipation unit 10 as the heat dissipation unit 10 for dissipating heat into the air supplied to the heat demanding facility 4 among the multiple heat dissipation units 10. As a result, heat dissipation from the third heat dissipation unit 10 to the heat demanding facility 4 begins.

[0054] Thereafter, the calculation process of the amount of heat dissipation Ha in step S110, the determination process of the amount of heat dissipation Ha in step S120, and the transport process in step S110 are repeated.

[0055] In this way, each time the heat dissipation amount Ha of the (N-1)th heat dissipation unit 10 falls below the threshold value, the conveying device 30 switches from the (N-1)th heat dissipation unit 10 to the Nth heat dissipation unit 10 as the heat dissipation unit 10 for dissipating heat into the air supplied to the heat demand facility 4.

[0056] In this embodiment, the transport device 30, together with the control device 40, constitutes a switching unit that switches from the (N-1)th heat dissipation unit 10 to the Nth heat dissipation unit 10 as the heat dissipation unit 10 for dissipating heat to the heat demanding facility 4.

[0057] In this manner, the heat dissipation units 10 dissipate heat one by one to the heat demand facility 4. After that, when all of the heat dissipation units 10 have finished dissipating heat, the heat dissipation units 10 are transported by the mobile object 6 from the heat dissipation tank 5A of the heat dissipation site 5 to the heat storage tank 3A of the heat storage site 3.

[0058] According to the present embodiment described above, the heat storage and release system 1 includes a plurality of heat release units 10 each including an adsorbent that stores heat, and a blower 20b that generates a flow of air passing through the plurality of heat release units 10.

[0059] The heat storage and release system 1 includes a transport device 30 and a control device 40. In each of the heat release units 10, the heat absorption agent absorbs moisture in the air from the blower 20b to generate heat, and releases the heat to the air that has passed through the heat absorption agent.

[0060] The transport device 30 is controlled by the control device 40 to switch the heat dissipation units 10 that dissipate heat into the air supplied to the heat demand facility 4 so that the amount of heat dissipated to the heat demand facility 4 is equal to or greater than the required value.

[0061] Here, as shown in FIG. 5, if the heat dissipation unit that dissipates heat to the heat demanding facility 4 is not switched and air from the heat demanding facility 4 is continuously blown to one heat dissipation unit 10A, the following problems will occur.

[0062] In this case, even if the adsorbent in one heat dissipation unit 10A is increased in size, the amount of heat dissipation of the heat dissipation unit 10A decreases over time and falls below the required value, as shown in Fig. 6. In Fig. 6, the vertical axis indicates the amount of heat dissipation of the heat dissipation unit 10A, the horizontal axis indicates time, and the graph Hg indicates the amount of heat dissipation that changes over time.

[0063] Accordingly, the temperature of the air discharged from the adsorbent of the heat dissipation unit 10 to the heat demand facility 4 (i.e., the adsorbent outlet temperature) decreases with time, as shown in Fig. 7. In Fig. 7, the vertical axis indicates the outlet temperature of the heat absorbent of the heat dissipation unit 10A, the horizontal axis indicates time, and Dt in Fig. 7 indicates the outlet temperature of the heat absorbent that decreases with time.

[0064] In contrast, in this embodiment, the transport device 30 switches the heat dissipation unit 10 to dissipate heat into the air supplied to the heat demanding facility 4. Therefore, the amount of heat dissipated to the heat demanding facility 4 can be maintained at or above the required value.

[0065] As a result, it is possible to provide the heat storage and release system 1 that supplies heat to the heat demanding facility 4 in a stable manner.

[0066] In this embodiment configured as above, the following operational effects (a), (b), and (c) can be obtained.

[0067] (a) The control device 40 calculates the amount of heat dissipation Ha to be dissipated to the heat demanding facility 4, and based on the calculated amount of heat dissipation Ha, controls the transport device 30 to switch the heat dissipation units 10 that dissipate heat to the heat demanding facility 4 so that the amount of heat dissipated to the heat demanding facility 4 is equal to or greater than the required value. Therefore, heat can be supplied to the heat demanding facility 4 more stably.

[0068] (b) The heat dissipation units 10 store heat in an adsorbent at the heat storage site 3, and the heat dissipation units 10 dissipate heat from the adsorbent to a heat demand facility 4 at the heat dissipation site 5. The heat dissipation units 10 are transported from the heat storage site 3 to the heat dissipation site 5 by a mobile object 6 with heat stored in the adsorbent.

[0069] On the other hand, the plurality of heat dissipation units 10 are transported by the mobile body 6 from the heat dissipation site 5 to the heat storage site 3 after completing the heat dissipation from the adsorbent to the heat demand facility 4. Therefore, the heat stored in the plurality of heat dissipation units 10 at the heat storage site 3 can be continuously dissipated to the heat demand facility 4.

[0070] (c) The adsorbent of the heat dissipation units 10 is a polymer adsorbent. Therefore, a large amount of heat can be stored in the heat dissipation units 10. This allows heat to be transferred continuously from the heat storage site 3 to the heat dissipation site 5.

[0071] Second embodiment In the above first embodiment, an example was described in which the control device 40 controls the transport device 30 to switch the heat dissipation units 10 that dissipate heat to the heat demand facility 4 so that the amount of heat dissipated to the heat demand facility 4 is always greater than or equal to the required value during the required period.

[0072] However, instead, an example will be described in which the control device 40 controls the transport device 30 to switch the heat dissipation units 10 that dissipate heat to the heat demand facility 4 at regular intervals so that the amount of heat dissipated to the heat demand facility 4 is greater than or equal to the required value.

[0073] The present embodiment differs from the above-described first embodiment mainly in the switching control process by the control device 40. Hereinafter, the switching control process by the control device 40 will be described with reference to Fig. 8. Fig. 8 is a flowchart showing the details of the switching control process. The control device 40 executes the switching control process according to the flowchart of Fig. 8, which replaces the flowchart of Fig. 4.

[0074] First, in step S100, the control device 40 controls the transport device 30 to transport a first heat dissipation unit 10 among the plurality of heat dissipation units 10 to the blowing destination of the blower 20b.

[0075] At this time, the blower 20b draws in high humidity air from the heat demand facility 4 and blows the drawn in high humidity air to the first heat dissipation unit 10.

[0076] In the first heat dissipation unit 10, the heat storage material absorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the heat absorption material. Therefore, the first heat dissipation unit 10 supplies high-temperature, low-humidity air to the heat demanding facility 4. In other words, the first heat dissipation unit 10 dissipates heat to the heat demanding facility 4.

[0077] Next, in step S110A, the control device 40 determines whether or not the heat dissipation time during which the first heat dissipation unit 10 has continuously dissipated heat to the heat demanding facility 4 is equal to or longer than a certain time Ta. The heat dissipation time is the time that has elapsed since the transport device 30 transported the first heat dissipation unit 10 to the blowing destination of the blower 20b.

[0078] At this time, in the above step S110A, when the heat radiation time of the first heat radiation unit 10 is less than the certain time Ta, the control device 40 determines NO. Accordingly, the control device 40 repeats the heat radiation time determination process of the above step S110A.

[0079] Therefore, the control device 40 repeats the NO determination in the above step S110A until the heat dissipation time of the first heat dissipation unit 10 becomes equal to or longer than the certain time Ta. After that, when the heat dissipation time of the first heat dissipation unit 10 becomes equal to or longer than the certain time Ta, the control device 40 determines YES in the above step S110A.

[0080] Accordingly, in step S100, the control device 40 controls the transport device 30 to transport the second heat dissipation unit 10, instead of the first heat dissipation unit 10, to the blowing destination of the blower 20b.

[0081] As a result, the transport device 30 switches the heat dissipation unit 10 for dissipating heat to the heat demanding facility 4 from the first heat dissipation unit 10 to the second heat dissipation unit 10 among the plurality of heat dissipation units 10.

[0082] The blower 20b draws in high-humidity air from the heat demand facility 4 and blows the drawn-in high-humidity air to the second heat dissipation unit 10. In the second heat dissipation unit 10, the heat storage material adsorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the heat storage material. Therefore, the second heat dissipation unit 10 supplies high-temperature, low-humidity air to the heat demand facility 4.

[0083] Thereafter, the control device 40 repeats the NO determination in the above step S110A until the heat dissipation time of the second heat dissipation unit 10 becomes equal to or longer than the certain time Ta.

[0084] Thereafter, in step S110A, the control device 40 determines YES when the heat dissipation time of the second heat dissipation unit 10 becomes equal to or longer than the certain time Ta. Then, in step S100, the control device 40 controls the transport device 30 to transport the third heat dissipation unit 10 to the blowing destination of the blower 20b instead of the second heat dissipation unit 10.

[0085] As a result, the transport device 30 is controlled by the control device 40 to switch from the second heat dissipation unit 10 to the third heat dissipation unit 10 as the heat dissipation unit 10 for dissipating heat to the heat demanding facility 4 among the multiple heat dissipation units 10. As a result, heat dissipation from the third heat dissipation unit 10 to the heat demanding facility 4 begins.

[0086] In this way, each time the heat dissipation time of the (N-1)th heat dissipation unit 10 becomes equal to or longer than a certain time Ta, the transport device 30 switches the heat dissipation unit 10 that dissipates heat to the heat demand facility 4 from the (N-1)th heat dissipation unit 10 to the Nth heat dissipation unit 10.

[0087] In this manner, the heat dissipation units 10 dissipate heat one by one to the heat demand facility 4. After that, when all of the heat dissipation units 10 have finished dissipating heat, the heat dissipation units 10 are transported by the mobile object 6 from the heat dissipation tank 5A of the heat dissipation site 5 to the heat storage tank 3A of the heat storage site 3.

[0088] According to the heat storage and release system 1 of the present embodiment described above, the transport device 30 is controlled by the control device 40 to switch the heat release units 10 that release heat into the air supplied to the heat demanding facility 4 at regular intervals Ta so that the amount of heat released to the heat demanding facility 4 is equal to or greater than a required value. As described above, it is possible to provide a heat storage and release system 1 that stably supplies heat to the heat demanding facility 4.

[0089] Third embodiment In the above second embodiment, an example has been described in which the transport device 30 transports the plurality of heat dissipation units 10 one by one to the heat demanding facility 4 in the heat dissipation tank 5A.

[0090] However, instead of this, an example in which the transport device 30 transports a plurality of heat dissipation units 10 so that two units at a time are dissipated from the heat dissipation unit 10 to the heat demanding facility 4 in the heat dissipation tank 5A will be described with reference to Figs. 9 and 10.

[0091] The present embodiment differs from the above-described second embodiment mainly in the switching control processing by the control device 40. The switching control processing by the control device 40 will be described below with reference to Fig. 9 and Fig. 10. Fig. 9 is a flowchart showing the details of the switching control processing of the present embodiment.

[0092] The control device 40 executes the switching control process according to the flowchart of Fig. 9, which replaces the flowchart of Fig. 8. Fig. 10 is a diagram for assisting in the explanation of the details of the switching control process of this embodiment.

[0093] First, in step S100A, the control device 40 controls the transport device 30 to transport the first and second heat dissipation units 10 among the plurality of heat dissipation units 10 to the blowing destination of the blower 20b.

[0094] At this time, the fan 20b blows out the high humidity air sucked in from the heat demand facility 4 to the first heat dissipation unit 10 and the second heat dissipation unit 10.

[0095] In the first heat dissipation unit 10 and the second heat dissipation unit 10, the heat storage material respectively absorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the heat storage material. Therefore, the first heat dissipation unit 10 and the second heat dissipation unit 10 supply high-temperature, low-humidity air to the heat demanding facility 4. In other words, the first heat dissipation unit 10 and the second heat dissipation unit 10 simultaneously dissipate heat to the air supplied to the heat demanding facility 4.

[0096] At this time, the same amount of air is blown from the fan 20b to the first heat dissipation unit 10 and the second heat dissipation unit 10. Therefore, the same amount of heat is released from the first heat dissipation unit 10 and the second heat dissipation unit 10.

[0097] Next, in step S110A, the control device 40 determines whether the heat dissipation times of the first heat dissipation unit 10 and the second heat dissipation unit 10 are equal to or longer than a certain time Ta.

[0098] The heat dissipation time is the time during which the first heat dissipation unit 10 and the second heat dissipation unit 10 have continued to dissipate heat since they started to dissipate heat in step S100A.

[0099] At this time, in the above step S110A, if the heat dissipation times of the first heat dissipation unit 10 and the second heat dissipation unit 10 are less than the certain time Ta, the control device 40 determines NO.

[0100] Accordingly, the control device 40 repeats the NO determination in the above step S110A until the heat dissipation times of the first heat dissipation unit 10 and the second heat dissipation unit 10 become equal to or longer than the certain time Ta. After that, when the heat dissipation times of the first heat dissipation unit 10 and the second heat dissipation unit 10 become equal to or longer than the certain time Ta, the control device 40 determines YES in the above step S110A.

[0101] Accordingly, in step S100A, the control device 40 controls the transport device 30 to transport the third heat dissipation unit 10, instead of the first heat dissipation unit 10, to the blowing destination of the blower 20b.

[0102] As a result, the transport device 30 switches the heat dissipation unit 10 for dissipating heat to the heat demanding facility 4 from the first heat dissipation unit 10 (i.e., the first heat dissipation unit) to the third heat dissipation unit 10 (i.e., the third heat dissipation unit).

[0103] For this reason, the blower 20b blows out the high humidity air sucked in from the heat demand facility 4 to the second heat dissipation unit 10 and the third heat dissipation unit 10. For this reason, in the second heat dissipation unit 10 and the third heat dissipation unit 10, the adsorbent adsorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the adsorbent.

[0104] Therefore, the second heat dissipation unit 10 and the third heat dissipation unit 10 supply high-temperature, low-humidity air to the heat demanding facility 4. That is, the second heat dissipation unit 10 and the third heat dissipation unit 10 simultaneously dissipate heat to the air supplied to the heat demanding facility 4.

[0105] At this time, the second heat dissipation unit 10 and the third heat dissipation unit 10 are supplied with the same amount of air from the fan 20b.

[0106] After that, in step S110A, the control device 40 determines whether the heat dissipation times of the second heat dissipation unit 10 and the third heat dissipation unit 10 are equal to or longer than a certain time Ta.

[0107] The heat dissipation times of the second and third heat dissipation units 10 are the time during which the second and third heat dissipation units 10 continue to dissipate heat after starting to dissipate heat to the heat demanding facility 4 in step S100A.

[0108] Next, the control device 40 repeats the NO determination in the above step S110A until the heat dissipation times of the second heat dissipation unit 10 and the third heat dissipation unit 10 reach or exceed the certain time Ta.

[0109] Thereafter, in step S110A, the control device 40 determines YES when the heat dissipation times of the second heat dissipation unit 10 and the third heat dissipation unit 10 become equal to or longer than the certain time Ta. Then, in step S100A, the control device 40 controls the transport device 30 to transport the fourth heat dissipation unit 10 to the blowing destination of the blower 20b instead of the second heat dissipation unit 10.

[0110] Here, the second heat dissipation unit 10 is a heat dissipation unit that dissipates heat for a longer period of time than the third heat dissipation unit 10. In other words, the second heat dissipation unit 10 is the first heat dissipation unit that dissipates heat for the longest period of time among the second heat dissipation unit 10 and the third heat dissipation unit 10.

[0111] The third heat dissipation unit 10 is a second heat dissipation unit other than the first heat dissipation unit among the second heat dissipation unit 10 and the third heat dissipation unit 10. The fourth heat dissipation unit 10 is a third heat dissipation unit that is not being used to dissipate heat to the heat demanding facility 4 among the multiple heat dissipation units 10. In other words, the fourth heat dissipation unit 10 is a heat dissipation unit that is not being used to dissipate heat to the heat demanding facility 4 among the multiple heat dissipation units 10.

[0112] As a result, the transport device 30 switches from the second heat dissipation unit 10 to the fourth heat dissipation unit 10 as the heat dissipation unit 10 for dissipating heat to the heat demanding facility 4 among the multiple heat dissipation units 10.

[0113] For this reason, the blower 20b blows out the high humidity air sucked in from the heat demand facility 4 to the third heat dissipation unit 10 and the fourth heat dissipation unit 10. For this reason, in the third heat dissipation unit 10 and the fourth heat dissipation unit 10, the adsorbent adsorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the adsorbent.

[0114] Therefore, the third heat dissipation unit 10 and the fourth heat dissipation unit 10 supply high-temperature, low-humidity air to the heat demanding facility 4. That is, the third heat dissipation unit 10 (i.e., the second heat dissipation unit) and the fourth heat dissipation unit 10 (i.e., the third heat dissipation unit) simultaneously dissipate heat to the heat demanding facility 4.

[0115] At this time, the third heat dissipation unit 10 and the fourth heat dissipation unit 10 are supplied with the same amount of air from the fan 20b.

[0116] Thereafter, in step S110A, the control device 40 determines YES when the heat dissipation times of the third heat dissipation unit 10 and the fourth heat dissipation unit 10 become equal to or longer than the certain time Ta. Then, in step S100A, the control device 40 controls the transport device 30 to transport the fifth heat dissipation unit 10 to the blowing destination of the blower 20b instead of the third heat dissipation unit 10.

[0117] The heat dissipation time of the third heat dissipation unit 10 and the fourth heat dissipation unit 10 is the time that the third heat dissipation unit 10 and the fourth heat dissipation unit 10 have continuously dissipated heat since they started to dissipate heat to the heat demand facility 4 in step S100A above.

[0118] Here, the third heat dissipation unit 10 is a heat dissipation unit that dissipates heat for a longer period of time than the fourth heat dissipation unit 10. In other words, the third heat dissipation unit 10 is the first heat dissipation unit that dissipates heat for the longest period of time among the third heat dissipation unit 10 and the fourth heat dissipation unit 10.

[0119] The fourth heat dissipation unit 10 is the second heat dissipation unit other than the first heat dissipation unit among the third heat dissipation unit 10 and the fourth heat dissipation unit 10. The fifth heat dissipation unit 10 is the third heat dissipation unit that is not being used to dissipate heat to the heat demanding facility 4 among the multiple heat dissipation units 10. In other words, the fifth heat dissipation unit 10 is the third heat dissipation unit that is not being used to dissipate heat to the heat demanding facility 4 among the multiple heat dissipation units 10.

[0120] As a result, the transport device 30 switches the heat dissipation unit 10 for dissipating heat to the heat demanding facility 4 from the third heat dissipation unit 10 to the fifth heat dissipation unit 10 among the plurality of heat dissipation units 10.

[0121] For this reason, the blower 20b blows out the high humidity air sucked in from the heat demand facility 4 to the fourth heat dissipation unit 10 and the fifth heat dissipation unit 10. For this reason, in the fourth heat dissipation unit 10 and the fifth heat dissipation unit 10, the adsorbent adsorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the adsorbent.

[0122] Therefore, the fourth heat dissipation unit 10 and the fifth heat dissipation unit 10 supply high-temperature, low-humidity air to the heat demanding facility 4. That is, the fourth heat dissipation unit 10 (i.e., the second heat dissipation unit) and the fifth heat dissipation unit 10 (i.e., the third heat dissipation unit) start dissipating heat to the heat demanding facility 4.

[0123] In this way, each time the heat dissipation time of the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 reaches or exceeds a certain time Ta, the transport device 30 switches the heat dissipation unit 10 that dissipates heat to the heat demand facility 4 as follows.

[0124] That is, each time the heat dissipation time of the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 reaches or exceeds a certain time Ta, the (N-1)th heat dissipation unit 10 is switched to the (N+1)th heat dissipation unit 10.

[0125] Therefore, each time the heat dissipation time of the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 reaches or exceeds a certain time Ta, the Nth heat dissipation unit 10 and the N+1th heat dissipation unit 10 start dissipating heat to the heat demand facility 4.

[0126] Here, the (N-1)th heat dissipation unit 10 is the first heat dissipation unit, the Nth heat dissipation unit 10 is the second heat dissipation unit, and the (N+1)th heat dissipation unit 10 is the third heat dissipation unit.

[0127] The heat dissipation time is the time during which the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 continue to dissipate heat to the heat demanding facility 4 after starting the heat dissipation in step S100A. Note that N, (N-1), and (N-1) are integers indicating the number of heat dissipation units 10. Next, the amount of heat dissipated from the heat dissipation tank 5A to the heat demanding facility 4 in this embodiment will be described with reference to FIG.

[0128] For ease of explanation, the amount of heat stored in the heat dissipation unit 10 that has been stored in the heat storage tank 3A and has not yet been dissipated in the heat dissipation tank 5A is defined as Nmax, and the amount of heat actually stored in the heat dissipation unit 10 is defined as Nz. The value obtained by dividing Nz by Nmax is defined as the heat storage remaining amount ratio Nh.

[0129] For example, the heat storage remaining amount ratio Nh of the heat dissipation unit 10 in an undissipated state in which heat has been stored in the heat storage tank 3A and has not yet been dissipated in the heat dissipation tank 5A is 1.0. The heat storage remaining amount ratio Nh of the heat dissipation unit 10 in a state in which half of Nmax has been dissipated in the heat dissipation tank 5A is 0.5.

[0130] In this embodiment, the certain time Ta is set so that the thermal storage remaining amount ratio Nh of the heat dissipation unit 10 decreases by 0.5.

[0131] In the first step S100A, the first heat dissipation unit 10 and the second heat dissipation unit 10 start dissipating heat to the heat demanding facility 4.

[0132] In the second step S100A, the heat storage remaining amount ratio Nh of the first heat dissipation unit 10 becomes 0.5. At this time, the heat dissipation unit 10 that dissipates heat to the heat demanding facility 4 is switched from the first heat dissipation unit 10 to the third heat dissipation unit 10. Accordingly, the third heat dissipation unit 10 replacing the first heat dissipation unit 10 and the second heat dissipation unit 10 start dissipating heat to the heat demanding facility 4.

[0133] In the third step S100A, the heat storage remaining amount ratio Nh of the second heat dissipation unit 10 becomes "0". At this time, the heat dissipation unit 10 that dissipates heat to the heat demanding facility 4 is switched from the second heat dissipation unit 10 to the fourth heat dissipation unit 10. Accordingly, the fourth heat dissipation unit 10 replacing the second heat dissipation unit 10 and the third heat dissipation unit 10 start dissipating heat to the heat demanding facility 4.

[0134] In the fourth step S100A, the heat storage remaining amount ratio Nh of the third heat dissipation unit 10 becomes "0". At this time, the heat dissipation unit 10 that dissipates heat to the heat demanding facility 4 is switched from the third heat dissipation unit 10 to the fifth heat dissipation unit 10. Accordingly, the fifth heat dissipation unit 10 replacing the third heat dissipation unit 10 and the fourth heat dissipation unit 10 start dissipating heat to the heat demanding facility 4.

[0135] In the fifth step S100A, the heat storage remaining amount ratio Nh of the fourth heat dissipation unit 10 becomes "0". At this time, the heat dissipation unit 10 that dissipates heat to the heat demanding facility 4 is switched from the fourth heat dissipation unit 10 to the sixth heat dissipation unit 10. Accordingly, the sixth heat dissipation unit 10 and the fifth heat dissipation unit 10, which replace the fourth heat dissipation unit 10, start dissipating heat to the heat demanding facility 4.

[0136] Next, a change in the amount of heat dissipated from the heat dissipation tank 5A to the heat demanding facility 4 in this embodiment will be described with reference to FIG. 10 and FIG.

[0137] 11 is a graph in which the vertical axis represents the amount of heat dissipated from heat dissipation tank 5A and the horizontal axis represents time. Graph Hn represents the amount of heat dissipated from heat dissipation tank 5A to heat demanding facility 4. Graph H1 represents the amount of heat dissipated from the first heat dissipation unit 10 to heat demanding facility 4.

[0138] Graph H2 represents the amount of heat dissipated from the second heat dissipation unit 10 to the heat demand facility 4. Graph H3 represents the amount of heat dissipated from the third heat dissipation unit 10 to the heat demand facility 4. Graph H4 represents the amount of heat dissipated from the fourth heat dissipation unit 10 to the heat demand facility 4. Graph H5 represents the amount of heat dissipated from the fifth heat dissipation unit 10 to the heat demand facility 4.

[0139] The timing when the first heat dissipation unit 10 and the second heat dissipation unit 10 start dissipating heat to the heat demand facility 4 is defined as timing T1. The timing when the second heat dissipation unit 10 and the third heat dissipation unit 10 start dissipating heat to the heat demand facility 4 is defined as timing T2.

[0140] The timing when the third heat dissipation unit 10 and the fourth heat dissipation unit 10 start to dissipate heat to the heat demand facility 4 is defined as timing T3. The timing when the fourth heat dissipation unit 10 and the fifth heat dissipation unit 10 start to dissipate heat to the heat demand facility 4 is defined as timing T4.

[0141] The timing at which the fifth heat dissipation unit 10 and the sixth heat dissipation unit 10 start dissipating heat to the heat demanding facility 4 is defined as timing T5.

[0142] Between timing T1 and timing T2, the amount of heat dissipation from heat dissipation tank 5A gradually decreases with time. After the amount of heat dissipation from heat dissipation tank 5A increases at timing T2, the amount of heat dissipation from heat dissipation tank 5A gradually decreases with time.

[0143] At time T3, the amount of heat dissipation from heat dissipation tank 5A increases, and then the amount of heat dissipation from heat dissipation tank 5A gradually decreases over time. At time T4, the amount of heat dissipation from heat dissipation tank 5A increases, and then the amount of heat dissipation from heat dissipation tank 5A gradually decreases over time.

[0144] After the amount of heat radiation from heat radiation tank 5A increases at timing T5, the amount of heat radiation from heat radiation tank 5A gradually decreases with the passage of time.

[0145] In contrast, if heat is continuously radiated from a single heat dissipation unit 10A to the heat demand facility 4, rather than switching the heat dissipation units 10 that radiate heat to the heat demand facility 4, as shown in Figure 5, the fluctuation in the amount of heat dissipated from the heat dissipation tank 5A to the heat demand facility 4, Whb, becomes large.

[0146] As described above, according to this embodiment, the change in the amount of heat dissipated from the heat dissipation tank 5A converges to a constant amount Wha after timing T2. Therefore, the amount of fluctuation in the amount of heat dissipated from the heat dissipation tank 5A to the heat demanding facility 4 can be made smaller than when heat is continuously dissipated from one heat dissipation unit 10A to the heat demanding facility 4.

[0147] According to the present embodiment described above, the conveying device 30 is controlled by the control device 40 to switch the heat dissipation units 10 that radiate heat to the heat demand facility 4 so that the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 simultaneously radiate heat to the heat demand facility 4.

[0148] As a result, the amount of heat dissipated from the heat dissipation tank 5A to the heat demanding facility 4 can be made equal to or greater than the required value. This makes it possible to provide the heat storage and dissipation system 1 that stably supplies heat from the heat dissipation tank 5A to the heat demanding facility 4.

[0149] In this embodiment, each time the heat dissipation time of the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 reaches or exceeds a certain time Ta, the conveying device 30 switches the heat dissipation unit 10 for dissipating heat into the air supplied to the heat demand facility 4 as follows.

[0150] That is, the transport device 30 switches from the (N-1)th heat dissipation unit 10 to the (N+1)th heat dissipation unit 10 every time the heat dissipation times of the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 reach or exceed a certain time Ta.

[0151] Therefore, each time the heat dissipation time of the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 reaches or exceeds a certain time Ta, the Nth heat dissipation unit 10 and the N+1th heat dissipation unit 10 start dissipating heat to the heat demand facility 4.

[0152] Here, the (N-1)th heat dissipation unit 10 is the first heat dissipation unit that has been dissipating heat for the longest time among the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10. The Nth heat dissipation unit 10 is the second heat dissipation unit among the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 excluding the (N-1)th heat dissipation unit 10. The N+1th heat dissipation unit 10 is the third heat dissipation unit that is not used to dissipate heat into air supplied to the heat demand facility 4.

[0153] As a result of the above, instead of the (N-1)th heat dissipation unit 10, whose heat storage remaining ratio Nh is "0", the (N+1)th heat dissipation unit 10, which is an unused heat dissipation unit, and the Nth heat dissipation unit 10 begin to dissipate heat to the heat demand facility 4.

[0154] Therefore, when heat dissipation by the (N-1)th heat dissipation unit 10 is terminated, the amount of heat remaining in the (N-1)th heat dissipation unit 10 can be reduced. This makes it possible to prevent the heat stored in the heat dissipation unit 10 from being wasted.

[0155] (Fourth embodiment) In the above first embodiment, an example in which the fan 20b blows air to the entire adsorbent in each heat dissipation unit 10 has been described.

[0156] However, instead, in the present fourth embodiment, an example in which the heat dissipation region 11 of the adsorbent 10a in the heat dissipation unit 10 to which air is blown from the blower 20b is displaced will be described with reference to Figures 12(a), (b), and (c).

[0157] Figures 12(a), (b), and (c) show specific examples in which the transport device 30 transports the Nth heat dissipation unit 10 and the (N+1)th heat dissipation unit 10, and the heat dissipation region 11 of the adsorbent 10a in the Nth heat dissipation unit 10 is displaced.

[0158] 12(a), (b), and (c), each of the heat dissipation units 10 has a rectangular columnar outer shape. The Nth heat dissipation unit 10 and the (N+1)th heat dissipation unit 10 each have an adsorbent 10a built in. The heat dissipation region 11 is a region of the adsorbent 10a that receives air blown out from the blower 20b and dissipates heat toward the heat demanding facility 4. The heat dissipation region 11 in this embodiment is formed in a rectangular shape.

[0159] Similar to the first embodiment, the heat storage and release system 1 of this embodiment includes a conveying device 30, a control device 40, an inlet temperature sensor 50a, an outlet temperature sensor 50b, an inlet air flow sensor 51a, an outlet air flow sensor 51b, an inlet humidity sensor 52a, and an outlet humidity sensor 52b.

[0160] The transport device 30 is controlled by the control device 40 to move the N-th heat dissipation unit 10 and the (N+1)-th heat dissipation unit 10 to the front in the traveling direction YKa.

[0161] Next, the switching control process performed by the control device 40 of this embodiment will be described with reference to FIG. The control device 40 executes a switching control process in accordance with the flowchart of FIG.

[0162] First, in step S100, the control device 40 controls the transport device 30 to transport the Nth heat dissipation unit 10 and the (N+1)th heat dissipation unit 10 and move the Nth heat dissipation unit 10 to the blowing destination of the blower 20b.

[0163] Here, the blower 20b draws in low-temperature, high-humidity air from the heat demand facility 4 and blows the drawn-in low-temperature, high-humidity air to the Nth heat dissipation unit 10. In this way, a heat dissipation area 11 is set in the Nth heat dissipation unit 10. The heat dissipation area 11 is a part of the Nth heat dissipation unit 10 to which air is supplied from the blower 20b.

[0164] In the heat dissipation area 11, the heat storage material absorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the heat storage material. Therefore, the heat dissipation area 11 blows out high-temperature, low-humidity air toward the heat demanding facility 4. In this way, the heat dissipation area 11 receives the air blown out from the blower 20b and dissipates heat to the heat demanding facility 4.

[0165] Next, in step S110, the control device 40 calculates the amount of heat dissipated Ha from the heat dissipation area 11 of the Nth heat dissipation unit 10 based on the output signals of the sensors 50a, 50b, 51a, 51b, and the like.

[0166] Next, in step S120, the control device 40 determines whether the amount of heat dissipation Ha of the heat dissipation area 11 is equal to or greater than a threshold value.

[0167] At this time, in the above step S120, when the amount of heat dissipation Ha of the heat dissipation region 11 is equal to or greater than the threshold value, the control device 40 determines YES. Accordingly, the control device 40 executes the calculation process of the amount of heat dissipation Ha in step S110.

[0168] Therefore, the control device 40 repeats the calculation process of the heat dissipation amount Ha in step S110 and the determination process of the heat dissipation amount Ha in step S120 until the heat dissipation amount Ha falls below the threshold value and the result of the determination in step S120 is NO.

[0169] Thereafter, when the amount of heat dissipation Ha becomes less than the threshold value, the control device 40 determines NO in step S120.

[0170] Accordingly, in step S100, the control device 40 controls the transport device 30 to transport the N-th heat dissipation unit 10 and the (N+1)-th heat dissipation unit 10. As a result, the N-th heat dissipation unit 10 and the (N+1)-th heat dissipation unit 10 move a predetermined distance forward in the traveling direction YKa.

[0171] As a result, the heat dissipation region 11 of the Nth heat dissipation unit 10 is displaced a predetermined distance rearward in the traveling direction YKa.

[0172] At this time, the blower 20b draws in low-temperature, high-humidity air from the heat demand facility 4 and blows out the drawn-in low-temperature, high-humidity air to the next heat dissipation area 11.

[0173] Therefore, in the next heat dissipation area 11, the heat storage material absorbs moisture in the air blown from the blower 20b, generates heat, and dissipates the heat to the air that has passed through the heat storage material. Therefore, the next heat dissipation area 11 supplies high-temperature, low-humidity air to the heat demanding facility 4. As a result, the next heat dissipation area 11 dissipates heat to the heat demanding facility 4.

[0174] Thereafter, the control device 40 repeats the calculation process of the heat dissipation amount Ha in step S110 and the determination process of the heat dissipation amount Ha in step S120 in the same manner as described above until the heat dissipation amount Ha of the next heat dissipation area 11 becomes less than the required value.

[0175] Thereafter, in step S120, the control device 40 determines that the heat dissipation amount Ha of the next heat dissipation area 11 is less than the required value and determines NO. Then, in step S100, the control device 40 controls the transport device 30 to move the Nth heat dissipation unit 10 and the (N+1)th heat dissipation unit 10 forward a predetermined distance in the traveling direction YKa.

[0176] As a result, the heat dissipation area 11 is displaced a predetermined distance rearward in the traveling direction YKa in the N-th heat dissipation unit 10. Therefore, heat dissipation to the heat demanding facility 4 is started from the displaced heat dissipation area 11.

[0177] Thereafter, the calculation process of the amount of heat dissipation Ha in step S110, the determination process of the amount of heat dissipation Ha in step S120, and the transport process in step S110 are repeated.

[0178] Next, a specific example of heat dissipation by the Nth heat dissipation unit 10 and the (N+1)th heat dissipation unit 10 of this embodiment will be described.

[0179] Fig. 12(b) shows an example in which the Nth heat dissipation unit 10 and the N+1th heat dissipation unit 10 in Fig. 12(a) have been moved to the left in the figure. Fig. 12(c) shows an example in which the Nth heat dissipation unit 10 and the N+1th heat dissipation unit 10 in Fig. 12(b) have been moved to the left in the figure.

[0180] For ease of explanation, the left region of heat dissipation area 11 in Fig. 12(a) is referred to as left region 11a, the right region of heat dissipation area 11 in Fig. 12(a) is referred to as right region 11b, and the left region of heat dissipation area 11 in Fig. 12(b) is referred to as left region 11c.

[0181] The right region of heat dissipation area 11 in Fig. 12(b) is referred to as right region 11d, the left region of heat dissipation area 11 in Fig. 12(c) is referred to as left region 11e, and the right region of heat dissipation area 11 in Fig. 12(c) is referred to as right region 11f.

[0182] The right region 11b of the heat dissipation region 11 in Fig. 12(a) and the left region 11c of the heat dissipation region 11 in Fig. 12(b) are common regions of the adsorbent 10a in the Nth heat dissipation unit 10. The right region 11d of the heat dissipation region 11 in Fig. 12(b) and the left region 11e of the heat dissipation region 11 in Fig. 12(c) are common regions of the adsorbent 10a in the Nth heat dissipation unit 10.

[0183] For ease of explanation, when the Nth heat dissipation unit 10 is in the state shown in Fig. 12(a), the heat dissipation area 11 is referred to as heat dissipation area 11A. When the Nth heat dissipation unit 10 is in the state shown in Fig. 12(b), the heat dissipation area 11 is referred to as heat dissipation area (i.e., second heat dissipation area) 11B. When the Nth heat dissipation unit 10 is in the state shown in Fig. 12(c), the heat dissipation area 11 is also referred to as heat dissipation area (i.e., second heat dissipation area) 11C.

[0184] First, as the transport device 30 transports the Nth heat dissipation unit 10, the heat dissipation area 11 is displaced from the heat dissipation area 11A to the heat dissipation area 11B. After that, the heat dissipation area 11 is displaced from the heat dissipation area 11B to the heat dissipation area 11C.

[0185] The left side region 11c in Fig. 12(b) is a region common to the heat dissipation regions 11A and 11B. Therefore, when the heat dissipation region 11 is in the state shown in Fig. 12(b), the left side region 11c in Fig. 12(b) becomes a second region having a longer heat dissipation time than the right side region (i.e., the first region) 11d.

[0186] The heat dissipation time is the cumulative time for dissipating heat to the heat demanding facility 4. When the heat dissipation area 11 is in the state shown in Fig. 12(b), the right-side area 11f in Fig. 12(c) is a third area that is not used for dissipating heat to the heat demanding facility 4. In other words, the right-side area 11f in Fig. 12(c) is a third area that is not used for dissipating heat to the heat demanding facility 4.

[0187] As described above, when heat dissipation region 11 changes from heat dissipation region 11B to heat dissipation region 11C, right region 11f and left region 11e replace left region 11c and form heat dissipation region 11C.

[0188] Then, heat dissipation is completed in the heat dissipation region 11C of the adsorbent 10a of the Nth heat dissipation unit 10. Then, the heat dissipation of the Nth heat dissipation unit 10 is completed, the heat dissipation region 11 is set to the N+1th heat dissipation unit 10, and the N+1th heat dissipation unit 10 starts dissipating heat.

[0189] As a result, the heat dissipation region 11 of the adsorbent 10a is displaced so that the amount of heat dissipated from the Nth heat dissipation unit 10 to the heat demanding facility 4 becomes equal to or greater than the required value.

[0190] According to the present embodiment described above, the transport device 30 is controlled by the control device 40 to move the N-th heat dissipation unit 10 and the (N+1)-th heat dissipation unit 10 forward in the traveling direction YKa.

[0191] As the Nth heat dissipation unit 10 moves, the heat dissipation area 11 shifts from heat dissipation area 11A to heat dissipation area 11B and then to heat dissipation area 11C. When the heat dissipation area 11 shifts from heat dissipation area 11B to heat dissipation area 11C, the right side area 11f and the left side area 11e replace the left side area 11c and form the heat dissipation area 11C.

[0192] Here, the left region 11e and the right region 11d are a common region in the adsorbent 10a of the Nth heat dissipation unit 10. In the heat dissipation region 11 in FIG. 12(b), the left region 11c has a longer heat dissipation time than the right region 11d.

[0193] 12(b), the right-side region 11f in FIG. 12(c) is a third region of the adsorbent 10a of the Nth heat dissipation unit 10 that is not used for dissipating heat to the heat demanding facility 4. For this reason, the heat dissipation region 11 of the adsorbent 10a is displaced so that the amount of heat dissipated from the Nth heat dissipation unit 10 to the heat demanding facility 4 becomes equal to or greater than the required value.

[0194] Therefore, heat can be stably supplied from the heat dissipation tank 5A to the heat demanding facility 4. In addition, when heat dissipation by the (N-1)th heat dissipation unit 10 is terminated, the amount of heat remaining in the (N-1)th heat dissipation unit 10 can be reduced. Therefore, it is possible to prevent the heat stored in the heat dissipation unit 10 from being wasted.

[0195] Fifth embodiment In the above fourth embodiment, an example has been described in which each of the heat dissipation units 10 is formed in a prismatic shape.

[0196] However, instead of this, in the present fifth embodiment, an example in which the plurality of heat dissipation units 10 are each formed in a disk shape will be described with reference to FIGS.

[0197] 13 shows a state in which three heat dissipation units 10 are arranged in a heat dissipation tank 5A to dissipate heat to a heat demanding facility 4. FIG 14 shows a state in which a heat dissipation area 11 is set in the heat dissipation unit 10.

[0198] Fig. 15 shows a state in which the heat dissipation unit 10 is rotated 45 degrees forward in the rotation direction YKb with respect to the heat dissipation unit 10 in Fig. 14. Fig. 16 shows a state in which the heat dissipation unit 10 is rotated 45 degrees forward in the rotation direction YKb with respect to the heat dissipation unit 10 in Fig. 15.

[0199] In this embodiment, each of the heat dissipation units 10 is formed in a disk shape centered on a central point Tx. The heat dissipation region 11 is a region of the adsorbent 10a that receives high-humidity, low-temperature air blown out from the blower 20b and blows out low-humidity, high-temperature air toward the heat demand facility 4.

[0200] The heat dissipation area 11 of this embodiment is formed in a semicircular shape as shown in Figures 14, 15, and 16. Figures 13, 14, 15, and 16 show specific examples in which air blown from the fan 20b to multiple heat dissipation units 10 flows in a direction perpendicular to the paper surface.

[0201] In this embodiment, the transport device 30 rotates one of the heat dissipation units 10 around a central point Tx. At this time, the blower 20b draws in high-humidity, low-temperature air from the heat supply facility 2 and blows the drawn-in high-humidity, low-temperature air to the heat dissipation region 11 of the one heat dissipation unit 10.

[0202] Accordingly, the heat dissipation unit 10 blows out high-temperature, low-humidity air from the heat dissipation area 11 to the heat demanding facility 4. As a result, the heat dissipation unit 10 releases heat from the heat dissipation area 11 to the heat demanding facility 4. At this time, as one heat dissipation unit 10 rotates, the heat dissipation area 11 of the adsorbent 10a of one heat dissipation unit 10 rotates.

[0203] Specifically, similarly to the fourth embodiment, the control device 40 calculates the amount of heat dissipation Ha of the heat dissipation area 11 based on the output signals of the sensors 50a, 50b, 51a, 51b, etc. The control device 40 determines whether the amount of heat dissipation Ha of the heat dissipation area 11 is equal to or greater than a threshold value.

[0204] The control device 40 rotates the heat dissipation unit 10 forward in the traveling direction YKa by a predetermined angle every time it is determined that the heat dissipation amount Ha of the heat dissipation area 11 is less than the threshold. The traveling direction YKa in this embodiment indicates the rotation direction of the heat dissipation unit 10. Thereby, the heat dissipation area 11 is displaced by a predetermined angle in the traveling direction YKa every time it is determined that the heat dissipation amount Ha of the heat dissipation area 11 is less than the threshold.

[0205] 13, in the heat dissipation tank 5A, the Nth heat dissipation unit 10 is rotated a predetermined number of rotations (e.g., one rotation) by the transport device 30. After that, the heat dissipation by the Nth heat dissipation unit 10 is completed, and the transport device 30 rotates the (N+1)th heat dissipation unit 10.

[0206] Therefore, a heat dissipation area 11 is set in the (N+1)th heat dissipation unit 10, and heat dissipation by the (N+1)th heat dissipation unit 10 is started. After that, when the transport device 30 rotates the (N+1)th heat dissipation unit 10 a predetermined number of rotations (e.g., one rotation), heat dissipation by the (N+1)th heat dissipation unit 10 is completed. After that, the transport device 30 starts rotating the (N+2)th heat dissipation unit 10.

[0207] For example, the heat dissipation unit 10 rotates forward in the rotation direction YKb, and the heat dissipation area 11 changes from the state in Fig. 14 to the state in Fig. 15. After that, the heat dissipation unit 10 rotates forward in the rotation direction YKb, and the heat dissipation area 11 changes from the state in Fig. 15 to the state in Fig. 16.

[0208] For ease of explanation, hereinafter, the heat dissipation area 11 when the heat dissipation unit 10 is in the state shown in Fig. 14 will also be referred to as heat dissipation area 11A. The heat dissipation area 11 when the heat dissipation unit 10 is in the state shown in Fig. 15 will also be referred to as heat dissipation area (i.e., first heat dissipation area) 11B. The heat dissipation area 11 when the heat dissipation unit 10 is in the state shown in Fig. 16 will also be referred to as heat dissipation area (i.e., second heat dissipation area) 11C.

[0209] Here, by rotating the heat dissipation unit 10 forward in the rotation direction YKb, the heat dissipation area 11B is set rearward in the rotation direction YKb with respect to the heat dissipation area 11A as shown in Fig. 15. As shown in Fig. 16, the heat dissipation area 11C is set rearward in the rotation direction YKb with respect to the heat dissipation area 11B.

[0210] 15, the common area between heat dissipation area 11A and heat dissipation area 11B is referred to as common area 61, and the area of ​​heat dissipation area 11B excluding common area 61 is referred to as area 60. The area of ​​heat dissipation area 11A excluding common area 61 is referred to as area 62.

[0211] 16, the common area between heat dissipation area 11B and heat dissipation area 1C is referred to as common area 64, and the area of ​​heat dissipation area 11C excluding common area 64 is referred to as area 63. The area of ​​heat dissipation area 11B excluding common area 64 is referred to as area 65.

[0212] 15, the area 63 in FIG. 16 is a third area that is unused for dissipating heat to the heat demanding facility 4. In the state of the heat dissipation area 11 shown in FIG. 16, the area 65 is an area that constitutes a part of the heat dissipation area 11A. Therefore, in the state of the heat dissipation area 11 shown in FIG. 16, the area 65 is an area that has a longer heat dissipation time than the common area 64.

[0213] As a result, the heat dissipation region 11 is displaced in the order of heat dissipation region 11A, heat dissipation region 11B, and heat dissipation region 11C. As a result, the heat dissipation region 11 in the adsorbent 10a is displaced so that the amount of heat dissipated from the heat dissipation unit 10 to the heat demand facility 4 becomes equal to or greater than the required value.

[0214] According to the present embodiment described above, the transport device 30 is controlled by the control device 40 to switch one by one the heat dissipation units 10 that dissipate heat to the heat demanding facility 4. This allows heat to be stably supplied from the heat dissipation tank 5A to the heat demanding facility 4.

[0215] In this embodiment, the heat dissipation unit 10 rotates and the heat dissipation area 11 changes from the heat dissipation area 11B to the heat dissipation area 11C. At this time, the area 63 replacing the area 65 and the common area 64 form the heat dissipation area 11C.

[0216] 15, an area 63 in FIG. 16 is an area that is not used for dissipating heat to the heat demanding facility 4. When the heat dissipation area 11 is in the state shown in FIG. 16, an area 65 is an area that has a longer heat dissipation time than the common area 64.

[0217] As a result, the heat dissipation region 11 of the adsorbent 10a is displaced so that the amount of heat dissipated from the heat dissipation unit 10 to the heat demand facility 4 becomes equal to or greater than the required value. In addition, when heat dissipation by the heat dissipation unit 10 is terminated, the amount of heat remaining in the heat dissipation unit 10 can be reduced. This makes it possible to prevent the heat stored in the heat dissipation unit 10 from being wasted.

[0218] Sixth embodiment In the above fifth embodiment, the example in which the heat dissipation region 11 of the adsorbent 10a of the heat dissipation unit 10 is formed in a semicircular shape has been described.

[0219] However, instead of this, as in the fifth embodiment, as shown in Figs. 17 and 18, the heat dissipation region 11 of the adsorbent 10a of the heat dissipation unit 10 may be formed in a circular shape.

[0220] Fig. 17 and Fig. 18 are diagrams showing the heat dissipation unit 10 and the heat dissipation region 11 of this embodiment. Fig. 18 shows a state in which the heat dissipation unit 10 of Fig. 17 has been rotated forward in a rotational direction YKb about a central point Tx.

[0221] For ease of explanation, the heat dissipation area 11 in the state of Fig. 17 is referred to as heat dissipation area 11A, and the heat dissipation area 11 in the state of Fig. 18 is referred to as heat dissipation area 11B. The heat dissipation area 11A is located forward of the heat dissipation area 11B in the rotation direction YKb.

[0222] According to the present embodiment described above, only the heat dissipation area 11 having a different shape from that of the fifth embodiment is used, and the other configurations are the same as those of the fourth embodiment. Therefore, similar to the fifth embodiment, when the heat dissipation by the heat dissipation unit 10 is terminated, the amount of heat remaining in the heat dissipation unit 10 can be reduced. Therefore, it is possible to prevent the heat stored in the heat dissipation unit 10 from being wasted.

[0223] (Other embodiments)

[0224] (a) In the above first to sixth embodiments, an example has been described in which a vehicle such as a truck is used as the mobile object 6 for transporting the heat dissipation unit 10 between the heat storage site 3 and the heat dissipation site 5. However, instead of this, a train, airplane, or the like for transporting cargo other than a vehicle such as a truck may be used as the mobile object 6.

[0225] (b) In the above fifth and sixth embodiments, examples have been described in which disk-shaped units are used as the plurality of heat dissipation units 10. However, instead of this, the plurality of heat dissipation units 10 may be formed in a shape other than a disk shape, for example, a spherical shape, a hemispherical shape, or a cylindrical shape.

[0226] (c) In the above first to sixth embodiments, an example has been described in which the transport device 30 moves the heat dissipation units 10 in order to switch the heat dissipation units 10 that dissipate heat to the heat demanding facility 4.

[0227] However, instead of this, the fan 20b may be moved in order to switch the heat dissipation unit 10 that dissipates heat to the heat demand facility 4. Alternatively, in order to switch the heat dissipation unit 10 that dissipates heat to the heat demand facility 4, the destination to which air is blown from the fan 20b may be displaced.

[0228] (d) In the above third embodiment, the fan 20b blows the air drawn in from the heat demanding facility 4 to the two heat dissipation units 10, causing the two heat dissipation units 10 to simultaneously dissipate heat to the heat demanding facility 4.

[0229] However, instead of this, the blower 20b may blow the air drawn in from the heat demanding facility 4 to three or more heat dissipation units 10 so that the three or more heat dissipation units 10 simultaneously dissipate heat to the heat demanding facility 4.

[0230] (e) In the above third embodiment, an example was described in which the Nth heat dissipation unit 10 and the N+1th heat dissipation unit 10 start dissipating heat to the heat demand facility 4 each time the heat dissipation time of the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 reaches or exceeds a certain time Ta.

[0231] However, instead, the control device 40 obtains the amount of heat dissipation Ha dissipated from the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10, and determines whether the amount of heat dissipation Ha is equal to or greater than a threshold value.

[0232] At this time, when the heat dissipation amount Ha of the (N-1)th heat dissipation unit 10 and the Nth heat dissipation unit 10 is less than a threshold value, the control device 40 controls the Nth heat dissipation unit 10 and the N+1th heat dissipation unit 10 to start dissipating heat to the heat demand facility 4.

[0233] (f) In the above fourth embodiment, an example was described in which the transport device 30 transports the Nth heat dissipation unit 10 and displaces the heat dissipation area 11 of the Nth heat dissipation unit 10 each time the heat dissipation amount Ha of the heat dissipation area 11 becomes less than the threshold value.

[0234] However, instead of this, the control device 40 may determine whether the heat dissipation time during which the heat dissipation area 11 has continuously dissipated heat to the heat demand facility 4 is equal to or longer than a certain time Ta. Every time the control device 40 determines that the heat dissipation time of the heat dissipation area 11 is equal to or longer than the certain time Ta, the control device 40 controls the transport device 30 to move the N-th heat dissipation unit 10 forward in the traveling direction YKa by a predetermined distance, thereby displacing the heat dissipation area 11.

[0235] (g) In the fifth embodiment described above, an example has been described in which the transport device 30 rotates the heat dissipation unit 10 to displace the heat dissipation region 11 of the heat dissipation unit 10 every time the heat dissipation amount Ha of the heat dissipation region 11 falls below the threshold value.

[0236] Alternatively, the control device 40 may control the conveying device 30 to rotate the Nth heat dissipation unit 10 forward in the traveling direction YKa to displace the heat dissipation area 11 each time it determines that the heat dissipation time of the heat dissipation area 11 is equal to or longer than a certain time Ta.

[0237] Similarly, in the above-described sixth embodiment, the control device 40 may control the conveying device 30 to rotate the Nth heat dissipation unit 10 forward in the traveling direction YKa to displace the heat dissipation area 11 each time it determines that the heat dissipation time of the heat dissipation area 11 is equal to or longer than a certain time Ta.

[0238] (h) In the above first to sixth embodiments, an example has been described in which high humidity air is supplied from the heat demanding facility 4 to the heat dissipation unit 10 so that the heat endothermic agent absorbs moisture and generates heat. However, this is not limiting, and air other than that from the heat demanding facility 4 (for example, air outside the heat demanding facility 4) may be supplied to the heat dissipation unit 10 as long as it is high humidity air.

[0239] That is, the heat dissipation unit 10 absorbs moisture in the outside air, generates heat, and dissipates the heat to the heat demanding facility 4.

[0240] (i) In the above first to sixth embodiments, the blower 20a is disposed on the upstream side of the air flow of the heat dissipation unit 10. However, instead of this, the blower 20a may be disposed on the downstream side of the air flow of the heat dissipation unit 10.

[0241] (j) In the above first to sixth embodiments, the blower 20b is disposed on the upstream side of the air flow of the heat dissipation unit 10. However, instead of this, the blower 20b may be disposed on the downstream side of the air flow of the heat dissipation unit 10.

[0242] (k) Note that the present disclosure is not limited to the above-described embodiments, and can be appropriately modified within the scope of the claims. Moreover, the above-described embodiments are not unrelated to each other, and can be appropriately combined, except when the combination is clearly impossible. Moreover, in each of the above-described embodiments, it goes without saying that the elements constituting the embodiments are not necessarily essential, except when it is particularly clearly stated that they are essential or when it is clearly considered to be essential in principle. Moreover, in each of the above-described embodiments, when the numbers, values, amounts, ranges, etc. of the components of the embodiments are mentioned, they are not limited to the specific numbers, except when it is particularly clearly stated that they are essential or when it is clearly limited to a specific number in principle.

Moreover, in each of the above-described embodiments, when it is described that external environment information of the vehicle (for example, humidity outside the vehicle) is obtained from a sensor, it is also possible to eliminate the sensor and receive the external environment information from a server or cloud outside the vehicle. Alternatively, it is possible to dispense with the sensor, obtain relevant information related to the external environment information from a server or cloud outside the vehicle, and estimate the external environment information from the obtained relevant information.
