Herein, the temperature adjusting device refers to a device which can bring about a change in temperature of itself or the environment when the device is operated, such as a refrigerator, an air conditioner, an air energy compressor, a solar heat collection and temperature adjustment device, a mobile robot heat release charger, a water heater, a heating and temperature adjustment device, a heating device, a compressor, a cold collection and temperature adjustment device, and a freezer.

The specific form of the energy storage station 10 is not limited, and the main function is to store energy, and the energy storage station 10 is provided with an energy storage material which can store energy and ensure the heat insulation of the energy storage station 10. The energy storage station 10 may be a thermally insulated tank filled with energy storage material. Or a storage pool dug on the ground, and the inner wall of the storage pool is subjected to heat insulation treatment.

In the energy storage station 10 according to the embodiment of the present invention, the stored energy may be divided into heat and cold, i.e., heat energy, according to the temperature of the energy. Therefore, the heat and the cold are relative concepts, and the division is only required according to a set limit (such as a temperature limit). Thus, in an alternative embodiment, the energy storage station 10 of an embodiment of the present invention may be a heat storage device (heat storage station) 11 or a cold storage device (cold storage station) 12.

The energy absorbing end 101 of the heat storage device 11 is a heat absorbing end 111 for absorbing heat of the first temperature adjusting device 1111 capable of generating heat, and the energy releasing end 102 is a heat releasing end 112 for releasing heat to the second temperature adjusting device 1121 requiring heat. For example, the first temperature adjusting device may be a refrigerator, an outdoor unit of an air conditioner during air conditioning, an air energy compressor, a solar heat collecting temperature adjusting device, a heat releasing charger of a mobile robot, and the like. The second temperature adjusting device can be a water heater, a heating air conditioner, a heating temperature adjusting device, a heating device and the like.

The energy storage station 10 of embodiments of the present invention may include one or more thermal storage devices 11, and one or more cold storage devices 12. The specific number and types of the settings can be determined according to the set application scene.

In the embodiment of the present invention, the energy storage station 10 described below may be referred to as a heat storage station 11 or a cold storage station 12, unless otherwise specified. When the energy storage station 10 is operating as the heat storage station 11, the energy absorbing terminal 101 is a heat absorbing terminal and the energy discharging terminal 102 is a heat discharging terminal. When the energy storage station 10 is operating as a cold storage station 12, the energy absorbing terminal 101 is a cold absorbing terminal and the energy discharging terminal 102 is a cold discharging terminal.

In the embodiment of the present invention, the energy storage station 10 can absorb energy generated by one or more temperature control devices at the same time, and can also release energy to one or more temperature control devices at the same time, so that according to the actual situation of the external temperature control device, one or more energy absorption terminals 101 and one or more energy release terminals 102 can be provided, and the specific number is determined according to the actual situation.

In the energy storage station 10 according to the embodiment of the present invention, the energy absorption end 101 is used for absorbing energy of the temperature adjustment device 1011 (the first temperature adjustment device 1111 and the third temperature adjustment device 1211) capable of generating corresponding energy, and the absorption modes are various, for example, when a fluid medium is used as a carrier, the energy absorption end 101 is communicated with a heat exchange device at the side of the temperature adjustment device 1011 at the absorption end through a pipeline by using a heat exchange device, and a medium circulation path is formed between the energy storage station 10 and the temperature adjustment device. The fluid medium absorbs the energy generated by the temperature adjusting device side and then flows to the energy absorption end 101 of the energy storage station 10, the energy storage material in the energy storage station 10 absorbs and stores the energy of the medium at the energy absorption end 101, the fluid medium after releasing the energy flows out to the heat exchange device at the temperature adjusting device side to absorb the energy generated by the temperature adjusting device side, and the circulation is carried out, so that the energy storage of the energy storage station 10 is completed.

In an alternative embodiment, the energy absorbing terminals 101 of the energy storage station 10 are one or more, each energy absorbing terminal 101 being independently located. For example, the energy absorption end 101 of the energy storage station 10 comprises one (as shown in fig. 5) or more first heat exchange devices (as shown in fig. 4), the first heat exchange device has an inlet pipe 141 and an outlet pipe 142 (i.e., a group of communicating pipes 14), and is communicated with the heat exchange device on the side of the absorption end temperature regulation device 1011 through two pipes, and energy conversion is performed between the temperature regulation devices (the first temperature regulation device 1111 and the third temperature regulation device 1211) and the energy storage station 10 through respective medium circulation paths. For another example, as shown in fig. 3, the energy absorption end 101 is a first heat exchange device, and the liquid inlet end of the first heat exchange device is connected to a plurality of liquid inlet pipes 141, and the liquid outlet end is connected to a plurality of liquid outlet pipes 142. One liquid inlet pipe 141 and one liquid outlet pipe 142 are used as a communicating pipe group 14 to form a plurality of independently arranged communicating pipe groups, and the communicating pipe groups are communicated with the terminal heat exchange device on the side of the external temperature regulating equipment. The energy absorption device is suitable for a scene that a plurality of external temperature adjustment devices input energy to the energy absorption end 101 at the same time. The flow control devices are arranged at the positions of the liquid inlet pipes at the liquid inlet end and the liquid outlet pipes at the liquid outlet end of the first heat exchange device, so that energy generated by one or more temperature adjusting devices can be absorbed simultaneously by controlling the flow control devices, the flow of media in a medium circulation pipeline of each temperature adjusting device is adjusted, and different heat exchange efficiencies are realized. In a further alternative embodiment, the energy absorption end 101 of the energy storage station 10 may further include a plurality of terminal heat exchangers, each terminal heat exchanger having a terminal liquid inlet pipe and a terminal liquid outlet pipe, which are respectively connected to the second liquid outlet pipe and the liquid inlet pipe of the first heat exchanger through two pipes. The terminal heat exchange device is arranged on the side of the temperature adjusting equipment 1011 at the absorption end and used for absorbing energy generated by the temperature adjusting equipment. The first heat exchanger and the terminal heat exchanger form a medium circulation path, and the energy generated by the temperature adjusting device is converted into the energy storage station 10 through a fluid medium. When the energy storage station 10 is the heat storage station 11, the terminal heat exchange device is arranged on the side of the first temperature regulating device 1111. When the energy storage station 10 is the cold storage station 12, the terminal heat exchanger is disposed on the third temperature control device 1211 side.

In another alternative embodiment, the energy absorbing end 101 of the energy storage station 10 is multiple, and the conduits of the multiple energy absorbing ends 101 are interconnected. The communication is performed in many ways as long as the heat exchange device on the temperature adjusting device side and the energy absorbing end 101 can form a medium circulation path. For example, as shown in fig. 6, the energy absorption terminals 101 are communicated with the liquid outlet transit line 152 through the liquid inlet transit line 151, the liquid inlet pipe 141 of each energy absorption terminal 101 is communicated with the liquid inlet transit line 151, and the liquid outlet pipe 142 of each energy absorption terminal 101 is communicated with the liquid outlet transit line 152.

That is, the liquid inlets of the energy absorption ports 101 (the first heat exchange devices) are communicated, and the liquid outlets are communicated. The flow control devices are arranged at the communication ports of the inlet liquid transfer pipeline 151 and the outlet liquid transfer pipeline 152, so that the energy generated by one or more temperature adjusting devices can be absorbed simultaneously, and the energy can be transmitted to one or more energy absorption ends 101.

Similarly, the energy releasing end 102 is used for releasing energy to the temperature adjusting equipment needing corresponding energy. For example, when a fluid medium is used as a carrier, the energy releasing end 102 is connected with the heat exchange device on the equipment side through a pipeline by using a heat exchange device, and a medium circulation path is formed between the energy storage station 10 and the releasing end temperature adjusting equipment 1021 (the second temperature adjusting equipment 1121 and the fourth temperature adjusting equipment 1221). The fluid medium absorbs the energy in the energy storage material of the energy storage station 10 in the energy release end 102 and then flows to the terminal heat exchange device at the side of the temperature regulating device 1021, the temperature regulating device side absorbs the energy in the fluid medium, the fluid medium after the energy release flows back to the energy release end 102 of the energy storage station 10, and the cycle is repeated, so that the energy release of the energy storage station 10 is completed.

The energy output scene of the energy release end 102 to a plurality of external temperature adjusting devices is adapted. The flow control devices are arranged at the liquid inlet pipes at the liquid inlet end and the liquid outlet pipes at the liquid outlet end of the second heat exchange device, and then the energy can be released to one or more temperature adjusting devices at the same time by controlling the flow control devices, the flow of media in a medium circulation pipeline of each temperature adjusting device is adjusted, and different heat exchange efficiencies are realized. In a further alternative embodiment, the energy discharging end 102 of the energy storage station 10 may further include a plurality of terminal heat exchanging devices, each having a terminal liquid inlet pipe and a terminal liquid outlet pipe, respectively connected to the liquid outlet pipe 142 and the liquid inlet pipe 141 of the second heat exchanging device through the two pipes. The terminal heat exchange device is arranged on the side of the temperature adjusting equipment and used for absorbing energy generated by the temperature adjusting equipment. The second heat exchange device and the terminal heat exchange device form a medium circulation path, and the energy in the energy storage station 10 is released to the temperature regulating equipment side through a fluid medium. When the energy storage station 10 is a heat storage station 11, the terminal heat exchange device is disposed at the side of the second temperature adjusting device 1121. When the energy storage station 10 is the cold storage station 12, the terminal heat exchange device is arranged on the fourth temperature regulating device 1221 side.

In another alternative embodiment, the energy release end 102 of the energy storage station 10 is multiple, and the multiple energy release ends 102 are interconnected. The communication mode is various, as long as the medium circulation path can be formed by the heat exchange device at the temperature adjusting device side and the energy releasing end 102.

And then the liquid inlet transit pipeline 151 and the liquid outlet transit pipeline 152 are used as a group of communicating pipeline group, and are communicated with a heat exchange device at the side of the temperature adjusting equipment through two pipelines, and energy conversion is carried out between the temperature adjusting equipment (the first temperature adjusting equipment and the third temperature adjusting equipment) and the energy storage station 10 through respective medium circulation passages. That is, the liquid inlets of the energy release ends 102 (the second heat exchange devices) are communicated, and the liquid outlets are communicated. The flow control devices are arranged at the communication ports on the liquid inlet transfer pipeline and the liquid outlet transfer pipeline, so that energy can be released from one or more energy release ends 102 at the same time, and energy can be released to one or more temperature adjusting devices at the same time.

Specifically, a first transfer heat exchanger is arranged between the heat storage device and the temperature adjusting equipment and between the cold storage device and the temperature adjusting equipment, and the first transfer heat exchanger plays a transfer role in heat energy conversion at two ends of the first transfer heat exchanger.

Specifically, the first intermediate heat exchanger 20 includes:

In another alternative embodiment, the heat absorbing end 201 is multiple, and the pipelines of the heat absorbing end 201 are communicated with each other. The communication may be performed in many ways as long as a plurality of heat absorbing terminals can be communicated with the energy storage station 10 (or the first temperature adjusting device 1111 or the fourth temperature adjusting device 1221).

By analogy, the control principle of the switching between the heat storage station 11 and the first tempering devices 1111 (absorption-side tempering devices) is the same and will not be described again here.

In the energy storage station according to the embodiment of the present invention, the number of the relay heat exchangers (the first relay heat exchanger and/or the second relay heat exchanger) connected between the energy storage station 10 and the temperature control device (the absorption-side temperature control device 1011 or the release-side temperature control device 1021) is not limited to fig. 5 or one of fig. 16 to 17, and may be connected in plural. For example, when the energy storage station is applied to a household, the number of temperature regulating devices is limited, and only one transfer heat exchanger is connected. When the energy storage station is applied to large-scale scenes such as communities and communities, the number of temperature adjusting devices is large, and the energy required to be stored is also large, so that the temperature adjusting devices can be grouped (for example, one group in one household), a plurality of energy storage stations 10 can also be arranged, each group of temperature adjusting devices exchanges energy with the energy storage stations 10 through one transfer heat exchanger, and also exchanges energy with the plurality of energy storage stations 10, and at this time, a plurality of transfer heat exchangers are connected. The determination is carried out according to specific conditions.
