Fig. 1 shows an alternative embodiment of an energy system.

In this alternative embodiment, as shown in fig. 1, the energy system includes two or more first heat source devices and two or more second heat source devices, and the energy system further includes two or more relay heat exchangers and two or more mixing units. The two or more intermediate heat exchangers include one or more high temperature intermediate heat exchangers and one or more low temperature intermediate heat exchangers.

The mixing unit comprises two heat absorption ends and a heat release end, one heat absorption end of the mixing unit is connected to a high-temperature transfer heat exchanger in the transfer heat exchanger, the other heat absorption end of the mixing unit is connected to a low-temperature transfer heat exchanger in the transfer heat exchanger, and the heat release end of the mixing unit is connected to a second heat source device corresponding to the heat absorption end. Two heat absorption ends of the mixing unit are respectively provided with a heat absorption valve, and a heat release end of the mixing unit is provided with a heat release valve.

The transfer heat exchanger exchanges heat with the first heat source equipment and is used for collecting heat or cold in the first heat source equipment. When the heat absorption valve of the mixing unit is opened, the high-temperature medium of the high-temperature transfer heat exchanger and the low-temperature medium of the low-temperature transfer heat exchanger are mixed in the mixing unit, and the mixed medium is supplied to the second heat source device for heat exchange.

Alternatively, the first heat source device is a condenser of a refrigerator, and the second heat source device is a condenser of an air conditioner in a heating mode.

Alternatively, the first heat source device is an evaporator of an air conditioner in a heating mode, and the second heat source device is an evaporator of a refrigerator. The cold energy output by the evaporator of the air conditioner is exchanged with the evaporator of the refrigerator through the transfer heat exchanger and the mixing unit, and is used for freezing or refrigerating food stored in the refrigerator.

Fig. 2 shows an alternative embodiment of the control method of the energy system.

In this alternative embodiment, the control method includes the steps of: and 11, controlling the opening time of two heat absorption valves of a mixing unit connected with the second heat source equipment according to the target temperature of the second heat source equipment. And step 12, controlling the opening time of a heat release valve of a mixing unit connected with the second heat source equipment according to the difference value between the target temperature and the actual temperature of the second heat source equipment.

By adopting the optional embodiment, the medium temperature in the mixing unit can be accurately adjusted by controlling the opening time of the two heat absorption valves, and when the heat release valve of the mixing unit is opened, the mixing unit is used for exchanging heat for the second heat source equipment. When the heat release valve of the mixing unit is closed, the second heat source equipment is disconnected with the mixing unit, namely the second heat source equipment and the first heat source equipment stop heat exchange.

The time for the second heat source equipment and the first heat source equipment to exchange heat is controlled according to the difference value of the target temperature and the actual temperature, the temperature difference is large, the heat exchange time is long, the temperature difference is small, the heat exchange time is short, each second heat source equipment can be uniformly heated up or cooled down, and the use experience of a user is guaranteed.

For example, the first heat source device is a condenser of a refrigerator, the second heat source device is a condenser of an air conditioner in a heating mode, and the condenser of the refrigerator exchanges heat with the condensers of the plurality of air conditioners through the intermediate heat exchanger and the mixing unit. When the temperature difference between the target temperature and the actual temperature of one air conditioner is larger, the air conditioner needs more heat exchange, and the opening time of a heat release valve of a mixing unit connected with the air conditioner is controlled to be longer so as to ensure that the temperature of the air conditioner is adjusted faster. When the temperature difference between the target temperature and the actual temperature of one air conditioner is small, the air conditioner needs less heat exchange, and the opening time of a heat release valve of a mixing unit connected with the air conditioner is controlled to be short, so that the temperature adjusting speed of each air conditioner is uniform.

For another example, the first heat source device is an evaporator of an air conditioner in a heating mode, the second heat source device is an evaporator of a refrigerator, and the evaporator of the air conditioner exchanges cold for the evaporators of the plurality of refrigerators through the intermediate heat exchanger and the mixing unit. When the temperature difference between the target temperature and the actual temperature of one of the refrigerators is larger, the refrigerator needs more cold exchange, and the opening time of a heat release valve of a mixing unit connected with the refrigerator is controlled to be longer so as to ensure that the temperature of the refrigerator is adjusted faster. When the temperature difference between the target temperature and the actual temperature of one of the refrigerators is small, the refrigerator needs less cold exchange, and the opening time of a heat release valve of a mixing unit connected with the refrigerator is controlled to be short, so that the temperature regulation speed of each refrigerator is uniform.

Optionally, the step of controlling the opening times of two heat absorption valves of a mixing unit connected to the second heat source device according to the target temperature of the second heat source device includes: obtaining a target temperature of the medium in the second heat source device according to the target temperature of the second heat source device; the opening times of two heat absorption valves of a mixing unit connected to the second heat source device are adjusted according to the target temperature of the medium in the second heat source device.

Alternatively, the energy system may be in units of homes, or in units of entire buildings, or in units of entire cells, or in units of a certain area.

Optionally, the number of mixing units is the same as the number of second heat source devices.

Optionally, the target temperature is a preset temperature set by a user, such as a freezing or refrigerating temperature of a refrigerator, and further such as an indoor temperature of an air conditioner.

Alternatively, the actual temperature of the second heat source device is obtained by a temperature sensor provided on the second heat source device.

In another optional embodiment, the method further comprises: acquiring the number of the second heat source devices which are in operation; and controlling the heat release valves of the mixing units connected with the second heat source equipment to open in a time sharing mode according to the number of the second heat source equipment in operation.

By adopting the optional embodiment, after the number of the second heat source devices which are in operation reaches a certain value, the second heat source devices which exchange heat with the first heat source devices are controlled by adopting a time-sharing opening method, so that the supply of media in the first heat source devices is ensured, and each second heat source device can be uniformly heated or cooled.

Optionally, the step of controlling the heat release valve of the mixing unit connected to the second heat source device to be opened in a time-sharing manner according to the number of the second heat source devices in operation includes: when the number of the second heat source devices in operation is smaller than a preset value, controlling a heat release valve of a mixing unit connected with the second heat source devices to be opened at all times; and when the number of the second heat source devices which are in operation is larger than a preset value, controlling heat release valves of the mixing units connected with the second heat source devices to be opened in a time sharing mode.

The full-time opening of the heat release valve of the mixing unit means that the opening time of the heat release valve of the mixing unit is not limited and the heat release valve of the mixing unit is not always opened.

With this alternative embodiment, the capacity of the first heat source device can be optimized, and more second heat source devices can be supplied to operate by the first heat source device having a smaller capacity.

Optionally, when the number of the second heat source devices in operation is greater than a preset value, the switched-in second heat source devices and the switched-out second heat source devices are controlled in a single-in single-out switching mode, and all the second heat source devices perform cyclic heat exchange with the mixing unit in the single-in single-out switching mode.

In another optional embodiment, the method further comprises: and controlling the number of the second heat source devices which simultaneously exchange heat with the first heat source devices according to the number of the second heat source devices which are in operation and the difference value between the target temperature and the actual temperature of each second heat source device.

Optionally, when the number of the second heat source devices in operation is greater than a preset value, the step of controlling the heat release valves of the mixing units connected with the second heat source devices to be opened in a time sharing mode includes: and controlling the number of simultaneously opened heat release valves of the mixing units connected with the second heat source devices according to the number of the second heat source devices which are in operation and the difference value between the target temperature and the actual temperature of the second heat source devices.

By adopting the optional embodiment, the reasonable supply of the heat or the cold of the first heat source equipment can be ensured, and the stable operation of the system can be ensured.

For example, the first heat source device is a refrigerator condenser, the second heat source device is an air conditioner condenser in a heating mode, and the refrigerator condenser exchanges heat with the plurality of air conditioner condensers through the intermediate heat exchanger and the mixing unit. The air conditioner condenser with the target temperature having a large difference with the actual temperature needs to exchange more heat with the refrigerator condenser compared with the air conditioner condenser with the target temperature having a small difference with the actual temperature, so that the difference between the target temperature and the actual temperature is an important basis for controlling the number of the refrigerator condenser connected to the air conditioner condenser. For example, for an air conditioner condenser with a large difference between the target temperature and the actual temperature, more heat exchange needs to be performed on a single air conditioner condenser, and therefore the number of the air conditioner condensers connected to the refrigerator condenser at the same time is controlled, and the situation that the heat energy supply of the system is insufficient is prevented. For another example, for an air conditioner condenser with a small difference between the target temperature and the actual temperature, a single air conditioner condenser needs to perform less heat exchange, and therefore, a refrigerator condenser can be connected with a large number of air conditioner condensers at the same time.

In another optional embodiment, the method further comprises: and controlling the opening time of a heat release valve of a mixing unit connected with the second heat source equipment according to the number of the second heat source equipment which is in operation and the difference value of the target temperature and the actual temperature of each second heat source equipment.

Optionally, the first heat source device is a refrigerator condenser, the second heat source device is an air conditioner condenser in a heating mode, and the refrigerator condenser exchanges heat with the plurality of air conditioner condensers through the transfer heat exchanger and the mixing unit. When the target temperature of the air conditioner is higher than the actual temperature, controlling the opening time of a heat release valve of a mixing unit connected with the air conditioner; and when the target temperature of the air conditioner is lower than the actual temperature, controlling a heat release valve of a mixing unit connected with the air conditioner to be closed.

Optionally, the first heat source device is an air conditioner evaporator in a heating mode, the second heat source device is a refrigerator evaporator, and the air conditioner evaporator exchanges cold for evaporators of a plurality of refrigerators through the intermediate heat exchanger and the mixing unit. When the target temperature of the refrigerator is lower than the actual temperature, controlling the opening time of a heat release valve of a mixing unit connected with the refrigerator; and when the target temperature of the refrigerator is higher than the actual temperature, controlling a heat release valve of a mixing unit connected with the refrigerator to be closed.

The heat exchange time of each second heat source device is different from that of the first heat source device, and the opening time of a heat release valve of a mixing unit connected with the second heat source device is controlled to be longer for the second heat source device with larger temperature difference between the target temperature and the actual temperature; and for the second heat source equipment with smaller difference between the target temperature and the actual temperature, the opening time of a heat release valve of the mixing unit connected with the second heat source equipment is controlled to be shorter.

For example, the first heat source device is a condenser of a refrigerator, the second heat source device is a condenser of an air conditioner in a heating mode, Δ T_nWhen the difference value of the target temperature and the actual temperature of the condenser of the air conditioner is delta T_nWhen the temperature is less than or equal to 0, controlling a heat release valve of a mixing unit connected with the condenser of the air conditioner to be closed.

As another example, the first heat sourceThe equipment is an air conditioner evaporator in a heating mode, the second heat source equipment is a refrigerator evaporator, delta T_nThe difference between the actual temperature of the evaporator and the target temperature is calculated as delta T_nAnd when the temperature is less than or equal to 0, controlling a heat release valve of a mixing unit connected with the refrigerator evaporator to be closed.

Optionally, the reference on-time t_baseAccording to the number of the second heat source devices being operated. Alternatively, the reference on time t is the smaller the number of second heat source devices that are operating_baseThe longer the number of second heat source devices that are operating is, the greater the reference on time t_baseThe shorter.

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.

An energy storage station according to an embodiment of the invention is described with reference to fig. 3a to 3 g.

Theenergy storage station 10, theenergy absorbing end 101 of theenergy storage station 10 is used for absorbing the energy of the temperature adjusting device (absorbing end temperature adjusting device 1011) capable of generating corresponding energy, and theenergy releasing end 102 is used for releasing the energy to the temperature adjusting device (releasing end temperature adjusting device 1021) needing corresponding energy.

The specific form of theenergy storage station 10 is not limited, and the main function is to store energy, and theenergy storage station 10 is provided with an energy storage material which can store energy and ensure the heat insulation of theenergy storage station 10. Theenergy 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.

The energy storage station of the embodiment of the invention can be applied to a single family and can also be applied to a cell or a community. The application scenarios are different, the number of temperature regulating devices is different, and the storage capacity of theenergy storage station 10 is different. For example, when applied in a single household setting, the number of temperature conditioning devices is limited, typically not exceeding 10. When the energy storage station is applied to a cell or even a larger community, the number of the external temperature adjustment devices is huge, and the energy storage amount of theenergy storage station 10 needs to be large. The energy storage station, when having an application, may be determined only by the actual situation.

In theenergy storage station 10 according to the embodiment of the present invention, the stored energy may be divided into heat and cold according to the temperature represented by the energy, and therefore, the heat and the cold are relative concepts and are divided according to a set limit (e.g., a temperature limit). Thus, in an alternative embodiment, theenergy storage station 10 of an embodiment of the invention may be a heat storage device (heat storage station) 11, a cold storage device (cold storage station) 12, or comprise both aheat storage device 11 and acold storage device 12.

Theenergy absorbing end 101 of theheat storage device 11 is aheat absorbing end 111 for absorbing heat of the firsttemperature adjusting device 1111 capable of generating heat, and theenergy releasing end 102 is aheat releasing end 112 for releasing heat to the secondtemperature 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.

Theenergy absorbing terminal 101 of thecold storage device 12 is a cold absorbing terminal 121 (i.e., a heat releasing terminal) for absorbing cold of the thirdtemperature adjusting apparatus 1211 capable of generating cold, and theenergy releasing terminal 102 is a cold releasing terminal 122 (i.e., a heat absorbing terminal) for releasing cold to the fourthtemperature adjusting apparatus 1221 requiring cold. For example, the third temperature adjusting device may be an outdoor unit of an air conditioner, a compressor, a cooling and temperature adjusting device, or the like, when the air conditioner is heating. The fourth temperature regulating device may be a refrigerator, an ice chest, a refrigerated air conditioner, or the like.

Theenergy storage station 10 of embodiments of the present invention may include one or morethermal storage devices 11, and one or morecold storage devices 12. As shown in fig. 3b, an energy storage station comprises aheat storage device 11 and acold storage device 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, theenergy storage station 10 described below may be referred to as aheat storage device 11 or acold storage device 12, unless otherwise specified. When theenergy storage station 10 is used as theheat storage device 11, theenergy absorbing terminal 101 is a heat absorbing terminal and theenergy discharging terminal 102 is a heat discharging terminal. When theenergy storage station 10 is used as thecold storage device 12, theenergy absorbing terminal 101 is a cold absorbing terminal and theenergy discharging terminal 102 is a cold discharging terminal.

In the embodiment of the present invention, theenergy 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 moreenergy absorption terminals 101 and one or moreenergy release terminals 102 can be provided, and the specific number is determined according to the actual situation.

In theenergy storage station 10 according to the embodiment of the present invention, theenergy absorption end 101 is used for absorbing energy of the temperature adjustment device 1011 (the firsttemperature 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, theenergy absorption end 101 is communicated with a heat exchange device at the side of thetemperature adjustment device 1011 at the absorption end through a pipeline by using a heat exchange device, and a medium circulation path is formed between theenergy 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 theenergy absorption end 101 of theenergy storage station 10, the energy storage material in theenergy storage station 10 absorbs and stores the energy of the medium at theenergy 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 theenergy storage station 10 is completed.

In an alternative embodiment, theenergy absorbing terminals 101 of theenergy storage station 10 are one or more, eachenergy absorbing terminal 101 being independently located. For example, theenergy absorption side 101 of theenergy storage station 10 comprises one (as shown in fig. 3 e) or more first heat exchange devices (as shown in fig. 3 d) having aninlet pipe 141 and an outlet pipe 142 (i.e. a group of communicating pipes 14) which communicate with the heat exchange device on the side of the absorption sidetemperature regulating device 1011 via two pipes, and energy is converted between the temperature regulating devices (the firsttemperature regulating device 1111 and the third temperature regulating device 1211) and theenergy storage station 10 via respective medium circulation paths. For another example, as shown in fig. 3c, theenergy 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 ofliquid inlet pipes 141, and the liquid outlet end is connected to a plurality ofliquid outlet pipes 142. Oneliquid inlet pipe 141 and oneliquid outlet pipe 142 are used as a communicatingpipe 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 theenergy 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, theenergy absorption end 101 of theenergy 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, and respectively connected to the liquid outlet pipe and the liquid inlet pipe of the first heat exchanger through two pipes.
