Adopt this optional embodiment, control terminal heat exchanger and the time that described condenser carries out heat exchange according to the differential value of target temperature and actual temperature, if temperature difference is big, then heat exchange time is long, and temperature difference is small, then heat exchange In a short time, each water heater can evenly heat up or cool down, ensuring the user's experience. When the target temperature of the water heater is set to be lower than the actual temperature, in order to realize the rapid cooling of the water in the water heater, the method controls the terminal heat exchanger of the water heater to exchange heat with the evaporator of the heat source equipment, so as to realize the rapid drop of the water temperature . Certainly, by controlling the terminal heat exchanger and the condenser of the heat source equipment to stop heat exchange, the drop of water temperature can also be realized, but because the water heater has insulation measures, the rate of water temperature drop is relatively slow.

For example, the number of water heaters that can be supplied by the condenser at the same time is 10. When the number of water heaters in operation is 15, the number of water heaters that are controlled to exchange heat with the condenser is 10 in a period of time, and the method of time-sharing is used to control The water heater connected to the condenser realizes the uniform heat exchange of multiple water heaters, so as to ensure the supply of medium in the condenser, so that each water heater can evenly heat up or cool down.

[0097] In the embodiment of the present invention, the energy storage unit 110 may use existing energy storage materials, such as molten salt, which can store heat. There are many types of molten salt, such as ceramic matrix molten salt. Another example is the ice bag, which can store cold energy. The shape of the energy storage unit is not limited, and it can be determined according to the physical properties of the energy storage material itself. For example, when molten salt is used, the energy storage unit adopts a rigid shell, and the molten salt is encapsulated in the rigid shell and placed in the rigid shell. A groove is formed on the body for embedding the absorption end heat exchange device and the release end heat exchange device.
[0098] The absorption end heat exchange device, that is, the energy absorption end 101, can be provided with one or more absorption end heat exchange devices in each energy storage stack.

[0101] In this embodiment, the first heat exchange coil is used for the absorption end heat exchange device; the second heat exchange coil is used for the release end heat exchange device. The use of coils can increase the heat exchange area with the heat storage unit and improve the efficiency of storage or release.
[0102] Further, the first heat exchange coils and the second heat exchange coils are alternately arranged in the energy storage unit.
[0103] When there is only one energy storage stack 100 in the energy storage station 10 of this embodiment, the communication pipeline between the absorption end heat exchange device 101 and the discharge end heat exchange device 102 adopts the aforementioned first to fourth energy storage station 10 The structure is fine.
[0104] When there are multiple energy storage stacks 100 in the energy storage station 10 of this embodiment, the connecting pipelines of the absorption end heat exchange device 101 and the discharge end heat exchange device 102 in each energy storage stack 100 are as follows Figure 3e or Figure 3f The setting method shown. And add a total liquid inlet pipe and a total liquid outlet pipe at the end of the absorption end heat exchange device 101.

In the same way, a total liquid inlet pipe and a main liquid outlet pipe are also added at the discharge end heat exchange device 102 end. The liquid inlet pipe (141 or 151) of each discharge end heat exchange device 102 is connected to the main liquid inlet pipe. The liquid outlet pipes (142 or 152) of the heat exchange device 102 at the discharge end are connected to the main liquid outlet pipe.
[0105] Combine Figure 4a to Figure 4f As shown, an intermediate conversion heat exchanger of the present invention, denoted as the intermediate conversion heat exchanger 20, includes: a heat absorption end 201, which is used to connect to the energy storage station 10/temperature regulation equipment (eg, the first temperature regulation equipment 1111 Or the fourth temperature adjustment device 1221); and, the heat release end 202 is used to connect to the temperature adjustment device (eg, the second temperature adjustment device 1121 or the third temperature adjustment device 1211)/energy storage station 10.
[0106] The intermediate conversion heat exchanger 20 in the embodiment of the present invention is connected between the energy storage station 10 and the temperature adjustment device, and plays a role in the transfer of energy between the energy storage station 10 and a plurality of temperature adjustment devices. In practical applications, the number of temperature regulating devices is not fixed, and it can be one, two, or even more; and the energy storage station 10 can also have one or more. Therefore, in the embodiment of the present invention, the heat transfer There are one or more heat-absorbing ends 201 and one or more heat-dissipating ends 202, which can realize multi-channel conversion, multi-channel conversion, or multi-channel conversion, which can facilitate the adjustment of the energy storage station 10 and the adjustment The energy storage and release between the temperature devices (the absorption end temperature adjustment device 1011 or the release end temperature adjustment device 1021), and the path control is convenient, according to the actual situation, some of the paths can be connected for energy exchange. Moreover, the communication pipeline between the energy storage station and the temperature control device can be simplified, the pipeline layout is convenient, and the cost is reduced.
[0107] In the intermediate conversion heat exchanger 20 of the embodiment of the present invention, when the heat absorption end 201 is connected to the energy storage station 10, the heat release end 202 is connected to the temperature adjustment equipment, and the energy storage station 10 supplies heat to the temperature adjustment equipment through the intermediate conversion heat exchanger 20 It may also be that the temperature regulating device supplies cold energy to the energy storage station through the intermediate heat exchanger 20. When the heat-absorbing end 201 is connected to the temperature regulating device, the heat-emitting end 202 is connected to the energy storage station 10, and the temperature regulating device supplies heat to the energy storage station 10. Alternatively, the energy storage station 10 supplies cold energy to the temperature regulating device.
[0108] In the embodiment of the present invention, the heat-absorbing end 201 is used to absorb the heat of the energy storage station 10 (or the first temperature adjustment device 1111), that is, the end of cooling capacity (releasing cooling capacity). Various specific structures are adopted. For example, a fluid medium is used as a carrier, and the heat-absorbing end 201 adopts a heat exchange device and the heat-exchanging device of the heat releasing end 112 on the side of the heat storage station 11 (or the first temperature regulating device 1111) passes through the pipeline. Connected, the fluid medium absorbs heat from the heat storage station 11 side (or the first temperature regulating device 1111), the fluid medium flows to the heat absorption end 201, and the heat absorption end 201 exchanges heat with the medium fluid at the heat release end 202, thereby The heat is transferred to the exothermic end 202. Alternatively, the heat-absorbing end 201 is connected with the heat exchange device of the cold-capacity absorption end 121 (or the fourth temperature adjustment device 1221) of the cold-capacity storage station 12 by a heat exchange device through a pipeline. At this time, the heat-absorption end 201 can understand To release the cold end 201, the fluid medium absorbs heat from the cold storage station 12 side (or the fourth temperature adjustment device 1221) (absorbs heat, that is, releases cold), and the fluid medium flows to the end 201 to absorb heat The end 201 exchanges heat with the medium fluid of the heat-emitting end 202 to transfer heat to the heat-emitting end 202.
[0109] In the same way, the heat release end 202 is used to release heat to the energy storage station 10 (or the second temperature adjustment device 1121), that is, the end that absorbs cold (absorbs cold). Various specific structures are adopted. For example, the fluid medium is used as the carrier, and the heat-exchanging device at the heat-releasing end 202 is used with the heat-exchanging device of the heat-absorbing end 111 on the side of the heat storage station 11 (or the second temperature regulating device 1121) through the pipeline Connected, the fluid medium absorbs heat from the heat storage station 11 side (or the second temperature adjustment device 1121), the fluid medium flows to the heat release end 202, and the heat release end 202 exchanges heat with the medium fluid at the heat absorption end 201, thereby The heat is transferred to the heat sink 201. Alternatively, the heat release end 202 is connected with the heat exchange device of the cold release end 122 (or the third temperature adjustment device 1211) of the cold storage station 12 by a heat exchange device through a pipeline, and the fluid medium is directed to the cold storage station 12 side (Or, the third temperature adjustment device 1211) releases heat (releases heat, that is, absorbs cold energy), the fluid medium flows to the heat release end 202, and the heat release end 202 exchanges heat with the medium fluid at the heat absorption end 201, thereby The heat is transferred to the heat sink 201.
[0110] That is, when the intermediate heat exchanger is applied to the cold energy storage device, the reverse process of the heat transfer in the intermediate heat exchanger 20 is cold energy transfer, that is, heat is absorbed and cold energy is released.
[0111] In an alternative embodiment, the heat-absorbing end 201 specifically adopts a heat exchange device, such as a plate heat exchanger, an evaporator, or a heat exchange coil. The exothermic end 202 specifically adopts a heat exchange device, such as a plate heat exchanger, a condenser, or a heat exchange coil.
[0112] In the intermediate heat exchanger 20 of the embodiment of the present invention, the number of the heat absorption end 201 and the heat release end 202, and the arrangement of the external connection pipeline group of the heat absorption end 201 and the heat release end 202 are based on the connection side (energy The number of connecting pipe groups of the heat exchange device on the storage station side and the temperature control equipment side (see the section on the energy storage device below) can be determined.
[0113] In an optional embodiment, there are one or more heat-absorbing ends 201 of the heat conversion device 20 in the embodiment of the present invention, and the pipes of each heat-absorbing end 201 are independently arranged. For example, the heat sink 201 includes one (such as Figure 4a , Figure 4b with Figure 4f Shown) or more (see Figure 4d The heat release end 202 of the intermediate heat exchanger 20) the third heat exchange device, each third heat exchange device has an inlet pipe 211 and a liquid outlet pipe 212 (ie, a set of connecting pipe sets 21), which pass through two Two pipelines are connected to the heat exchange device on the side of the energy storage station 10 (or the first temperature regulating device 1111 or the fourth temperature regulating device 1221), and the energy storage station 10 (or the first temperature regulating device 1111 or The heat on the side of the fourth temperature regulating device 1221) is transferred to the heat absorbing end 201. That is, each third heat exchange device independently communicates with the energy storage station 10 (or the first temperature adjustment device 1111 or the fourth temperature adjustment device 1221). Another example, such as Figure 4c , Figure 4e As shown, the heat absorption end 201 is a third heat exchange device, and the liquid inlet end of the third heat exchange device is connected to a plurality of liquid inlet pipes 211, and the liquid outlet end is connected to a plurality of liquid outlet pipes 212. A liquid inlet pipe 211 and a liquid outlet pipe 222 are used as a connecting pipeline group 21 to form a plurality of independent connecting pipeline groups, through which the plurality of independent connecting pipeline groups are respectively exchanged with the third heat exchange on the side of the external temperature regulating device The device is connected.
[0114] In another alternative embodiment, there are multiple heat-absorbing ends 201, and the pipes of the multiple heat-absorbing ends 201 are connected to each other. There are many ways to communicate with each other, as long as multiple heat absorption ends can be connected to the energy storage station 10 (or the first temperature regulating device 1111 or the fourth temperature regulating device 1221). For example, such as Figure 4d As shown, a plurality of heat absorption ends 201 are communicated with a liquid inlet transfer pipeline 221 and a liquid outlet transfer pipeline 222. The liquid inlet pipe 211 of each heat absorption end 201 is connected with the liquid inlet transfer pipeline 221, and each heat sink The liquid outlet pipe 212 of the end 201 is in communication with the liquid outlet transfer pipeline 222. Then pass the inlet transfer pipeline 221 and the outlet transfer pipeline 222 as a set of connected pipeline groups, and pass through two pipelines to the energy storage station 10 (or the first temperature regulating device 1111 or the fourth temperature regulating device 1221) The heat exchange device on the side is connected.
[0115] In the same way, when there are one or more radiating ends 202, the pipes of each radiating end 202 are arranged independently, and the setting method is the same as the aforementioned heat absorbing end 201. When there are multiple radiating ends 202, the pipes of the multiple radiating ends 202 are connected to each other, and the connection method is the same as the aforementioned heat absorbing end 201. I will not repeat them here.
[0116] Therefore, in the intermediate heat exchanger of the embodiment of the present invention, there are the following specific embodiments according to the arrangement of the pipes of the heat absorption end 201 and the heat exchange end 202.
[0117] Such as Figure 4a As shown, in the intermediate heat exchanger I, there is one heat-absorbing end 201 with one connecting pipe group; there are multiple heat-releasing ends 202, and the connecting pipe groups of the multiple heat-releasing ends 202 are independently arranged. That is, the pipes of the heat absorbing end 201 and the heat radiating end 202 are provided independently. Turn all the way to many ways.
[0118] Such as Figure 4b As shown in the middle heat exchanger II, there is one heat-absorbing end 201 with one connecting pipe group; one heat-releasing end 202, and one heat releasing end 202 has a plurality of independently arranged connecting pipe groups.

That is, the pipes of the heat absorbing end 201 and the heat radiating end 202 are provided independently. Turn all the way.
[0123] Of course, the structure of the intermediate heat exchanger in the embodiment of the present invention is not limited to the above six types, and the structures of the heat absorption end 201 and the heat release end 202 can be interchanged or combined arbitrarily. The number of connecting pipe groups of the heat exchange device on the connecting side (the energy storage station side and the temperature regulating equipment side) determines the structure of the suitable intermediate heat exchanger. In addition, when there are multiple sets of connecting pipe groups at the heat absorption end 201 (or the heat release end 202) of the intermediate conversion heat exchanger, the number is not limited, and depends on the number of energy storage stations 10 or temperature regulation equipment to be connected. OK.
[0124] In the intermediate heat exchanger 20 of the embodiment of the present invention, the heat exchange device of the heat absorption end 201 and the heat exchange device of the heat release end 202 can be arranged separately, for example, when a plate heat exchanger is used, the two are arranged oppositely (contactable or No contact) to ensure the maximum heat exchange area; when heat exchange coils are used, the coils of the two are arranged alternately (contact or non-contact) to ensure effective heat exchange. Alternatively, the heat exchange device of the heat absorption end 201 and the heat exchange device of the heat release end 202 are designed as a whole. The arrangement method is not limited, as long as it is realized that the heat exchange device at the heat absorption end 201 and the heat exchange device at the heat release end 202 can perform heat transfer. Such as Figure 4a to Figure 4f As shown, both the heat-absorbing end 201 and the heat-dissipating end 202 adopt a non-contact heat exchange device structure. Of course, the heat exchanger in the embodiment of the present invention is not limited to the structure given in the drawings.

The energy storage station 10 can be controlled according to the actual situation. To release energy to part of the temperature regulating equipment, it is also possible to control part of the temperature regulating equipment box energy storage station 10 to store energy.
[0126] Combine Figure 4g with Figure 4h As shown, in the embodiment of the present invention, an intermediate conversion heat exchanger is also provided. The intermediate conversion heat exchanger 30 includes: a heat absorption end 301 for connecting to the energy storage station 10/temperature adjustment equipment (eg, the first temperature adjustment Device 1111 or fourth temperature regulating device 1221); heat release end 302, used to connect to temperature regulating device (eg, second temperature regulating device 1121 or third temperature regulating device 1211)/energy storage station 10; and, one-way guide The heat device 31, the heat absorption end 301 and the heat release end 302 are arranged at both ends of the unidirectional heat conduction device 31.
[0127] The intermediate conversion heat exchanger 30 of the embodiment of the present invention can provide precise energy for the temperature control equipment when the energy storage station releases energy to the discharge end temperature control equipment by adding the one-way heat conduction device 31. In addition, it is also applicable to situations where energy transmission between the energy storage station 10 and the temperature adjustment device (the absorption end temperature adjustment device 1011 or the release end temperature adjustment device 1021) cannot be carried out in a set direction. Generally, heat can only be transferred from the high temperature end to the low temperature end. If the temperature in the heat storage station itself is higher than the temperature of the medium output by the temperature regulating device, at this time, the heat storage station still has a lot of heat supply The storage capacity, at this time, the heat storage station cannot be stored in the set direction, but it will cause the heat loss of the heat storage station, which has the opposite effect. The same problem is encountered when the heat storage station releases heat. Therefore, the embodiment of the present invention provides the intermediate heat transfer device 30, which uses the unidirectional heating device 31 to control the temperature of the medium leading from the temperature regulating device to the heat (cold capacity) storage station, and the medium from the heat (cold capacity) storage station to the equipment The temperature is adjusted so that it can provide accurate energy to the temperature regulating device at the discharge end, or the energy storage station 10 and the temperature regulating device can transfer heat normally in a set direction.
[0128] The intermediate heat transfer device 30 of the embodiment of the present invention is based on the aforementioned intermediate heat transfer device 20, and a single heat conduction device 31 is added between the heat absorption end and the heat release end. Therefore, the structure of the absorption end 301 and the heat release end 302 of the intermediate heat transfer unit 30 and their functions are the same as the heat absorption end 201 and heat emission end 202 of the intermediate heat transfer unit 20. Please refer to the foregoing content. This will not be repeated here.
[0129] Therefore, based on Figure 4a to Figure 4f In the structure of the intermediate heat transfer device I to the intermediate heat transfer device VI, the one-way heat conducting device 31 is added between the heat absorption end and the heat release end to sequentially obtain the intermediate heat transfer device corresponding to the heat absorption end and the heat release end. Ⅰ to middle conversion heat exchanger Ⅵ. Such as Figure 4g The intermediate heat transfer device Ⅱ 30 shown is obtained by adding a one-way heat conducting device 31 on the basis of the intermediate heat transfer device Ⅱ 20, such as Figure 4h The intermediate heat transfer device VI30 shown is obtained by adding a one-way heat conduction device 31 to the intermediate heat transfer device VI20.
[0130] In the intermediate heat transfer device 30 and the one-way heat conducting device 31 of the embodiment of the present invention, the heat from the heat absorption end is (forcibly) exchanged to the heat release end. Specifically, a refrigerant heat exchanger or a semiconductor temperature regulator can be used.
[0131] In an alternative embodiment, the refrigerant heat exchanger includes an evaporator 311, a compressor (not shown), a condenser 312 and an expansion valve (not shown), and the four are connected to form a heat exchange circuit. The intermediate heat exchanger 30 includes two heat-absorbing chambers 303 and a heat-releasing chamber 304 that are arranged in adiabatic heat preservation; the evaporator 311 is arranged opposite to the heat-absorbing end 301 of the intermediate heat exchanger 30 and is arranged in the heat-absorbing chamber 303 The condenser 312 is opposite to the heat release end 302 of the intermediate heat exchanger 30, and is arranged in the heat release chamber 304.
[0132] In another alternative embodiment, the semiconductor temperature regulator includes a semiconductor refrigeration fin, a first end heat exchanger arranged at the first end of the pelvis and a second end heat exchanger at the second end, and a power supply Device. The power supply device is used to provide electrical energy for the semiconductor refrigeration sheet. By controlling the direction of the power supply current, the first end and the second end of the peltier can be switched in two modes of heat generation and cold generation. For example, under a forward current, the first end is the cold end and the second end is the hot end; after switching the current direction, the first end is switched to the hot end and the second end is switched to the cold end. The intermediate heat exchanger 30 includes two heat-absorbing chambers 303 and a heat-releasing chamber 304 that are provided with adiabatic heat preservation; the first end heat exchanger is arranged opposite to the heat-absorbing end 301 of the intermediate heat exchanger 30 and is arranged in the heat-absorbing cavity In the chamber 303; the second-end heat exchanger is opposite to the heat-radiating end 302 of the heat exchanger 30, and is placed in the heat-radiating chamber 304. According to the actual situation, it is sufficient to determine the first end heat exchanger as the hot end (or cold end) and the second end heat exchanger as the cold end (or hot end).
[0133] When it is necessary to provide accurate energy to the temperature regulating device at the release end, or when the heat transfer between the energy storage station 10 and the temperature regulating device cannot be carried out in the set direction, the unidirectional heat conducting device 31 is activated to reduce the heat of the heat sink 301 It is forced to exchange to the heat release end 302, and then the heat release end 302 transfers the heat to the energy storage station 10 (or the absorption end temperature adjustment device 1011, or the release end temperature adjustment device 1021).
