Description

Technical Field

[0001] This invention relates to the field of energy storage technology, specifically to a three-storage and three-supply system. Background Technology

[0002] Current building energy systems generally face prominent problems of single energy supply structure and insufficient sustainability when dealing with regions with complex climate conditions. Traditional technical routes are mostly limited to unidirectional energy storage mode. In winter, the thermal storage system is idle during the non-heating season, while the summer cooling demand requires additional independent cold source equipment. This fragmented energy supply mode not only causes thermal environment imbalance of underground energy storage, but also leads to a large amount of renewable energy not being effectively utilized. More limitingly, the separate operation of the heating and cooling systems forces buildings to rely on high energy for load regulation, resulting in the overall energy efficiency of the system being at a low level for a long time. To address this, a three-storage and three-supply system is proposed. Summary of the Invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides a three-storage and three-supply system.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a three-storage and three-supply system, comprising a thermal energy collection, storage and supply module, a cold energy collection, storage and supply module, an electric power storage and supply module, a hydraulic thermal barrier terminal module and an energy supply supplement module;

[0005] The thermal energy collection, storage and supply module is used to collect and store thermal energy, and the thermal energy collection, storage and supply module is connected to the hydraulic thermal barrier terminal module and supplies thermal energy to the hydraulic thermal barrier terminal module.

[0006] The cold energy collection, storage and supply module is used to collect and store cold energy. The cold energy collection, storage and supply module is connected to the hydraulic thermal barrier terminal module and supplies cold energy to the hydraulic thermal barrier terminal module.

[0007] The energy replenishment module is connected to the thermal energy collection, storage and supply module and the cold energy collection, storage and supply module respectively, and the energy replenishment module is used to replenish the thermal energy collection, storage and supply module and the cold energy collection, storage and supply module.

[0008] The power storage and supply module is electrically connected to the heat energy collection and storage supply module, the cold energy collection and storage supply module, and the power supply supplement module, and the power storage and supply module supplies electrical energy to the heat energy collection and storage supply module, the cold energy collection and storage supply module, and the power supply supplement module.

[0009] Preferably, the thermal energy collection, storage and supply module includes a heat collection device TC, a short-term thermal storage body SHCS and a long-term thermal storage body LHCS. The heat collection device TC is installed at the heat source, the short-term thermal storage body SHCS is connected to the heat collection device TC, and the long-term thermal storage body LHCS is connected to the short-term thermal storage body SHCS.

[0010] Preferably, the heat collection device TC collects thermal energy from the heat source. When the temperature of the thermal energy collected by the heat collection device TC is 3°C or higher than the temperature of the thermal energy stored in the short-term thermal storage body SHCS, the heat collection device TC sends the collected thermal energy to the short-term thermal storage body SHCS for storage through a medium.

[0011] When the temperature of the thermal energy stored in the short-term thermal storage body SHCS is 3°C or higher than the temperature of the thermal energy stored in the long-term thermal storage body LHCS, the short-term thermal storage body SHCS will transfer the thermal energy stored in itself to the long-term thermal storage body LHCS for storage through a medium.

[0012] The energy replenishment module operates during off-peak electricity price periods to replenish thermal energy to the long-term thermal storage body LHCS.

[0013] Preferably, when the temperature of the thermal energy stored in the short-term thermal storage body SHCS meets the heating requirements, the short-term thermal storage body SHCS supplies thermal energy to the hydraulic thermal barrier terminal module through a medium.

[0014] When the temperature of the thermal energy stored in the short-term thermal storage body SHCS does not meet the heating requirements, the long-term thermal storage body LHCS supplies thermal energy to the short-term thermal storage body SHCS through a medium, and then the short-term thermal storage body SHCS supplies thermal energy to the hydraulic thermal barrier terminal module through a medium.

[0015] After the long-term thermal storage medium (LHCS) supplies heat energy to the short-term thermal storage medium (SHCS), its own stored heat energy decreases. The long-term thermal storage medium (LHCS) serves as the heat source for the energy supplementation module. The energy supplementation module replenishes heat to the long-term thermal storage medium (LHCS), thereby improving its quality. After replenishment, the long-term thermal storage medium (LHCS) transfers heat energy to the short-term thermal storage medium (SHCS) through a medium. The short-term thermal storage medium (SHCS) then supplies heat energy to the hydraulic thermal barrier terminal module through the medium. After the medium releases heat in the hydraulic thermal barrier terminal module, it flows back into the short-term thermal storage medium (SHCS). The short-term thermal storage medium (SHCS) then returns the heat-released medium to the energy supplementation module to replenish heat energy.

[0016] Preferably, the cold energy collection, storage and supply module includes a cold collection device CC, a short-term cold storage body SCCS and a long-term cold storage body LCCS, wherein the short-term cold storage body SCCS is connected to the cold collection device CC and the long-term cold storage body LCCS is connected to the short-term cold storage body SCCS.

[0017] Preferably, when the ambient temperature is 3°C or more below the temperature of the cold energy stored in the short-term cold storage body SCCS, the cold collection device CC collects cold energy from the cold source and sends the cold energy to the short-term cold storage body SCCS for storage through a medium.

[0018] When the temperature of the cold energy stored in the long-term cold storage body LCCS is 3°C or higher than the temperature of the cold energy stored in the short-term cold storage body SCCS, the short-term cold storage body SCCS will transfer the cold energy it stores to the long-term cold storage body LCCS through a medium.

[0019] The energy replenishment module operates during off-peak electricity price periods to replenish the cooling energy of the long-term cold storage body (LCCS).

[0020] Preferably, when the temperature of the cold energy stored in the short-term cold storage body SCCS meets the cooling requirements, the short-term cold storage body SCCS directly supplies cold energy to the hydraulic thermal barrier terminal module through a medium.

[0021] When the temperature of the cold energy stored in the short-term cold storage body SCCS does not meet the cooling requirements, the long-term cold storage body LCCS transfers cold energy to the short-term cold storage body SCCS through a medium, and then the short-term cold storage body SCCS supplies cold energy to the hydraulic thermal barrier terminal module through a medium.

[0022] After supplying cold energy to the short-term cold storage module SCCS, the long-term cold storage module LCCS reduces its own stored cold energy. The long-term cold storage module LCCS acts as a cold source for the energy supplement module. The energy supplement module replenishes the cold energy of the long-term cold storage module LCCS, thereby improving the quality of the long-term cold storage module LCCS. After replenishment, the long-term cold storage module LCCS transfers cold energy to the short-term cold storage module SCCS through a medium. The short-term cold storage module SCCS then transfers cold energy to the hydraulic thermal barrier terminal module through a medium. After the medium is released in the hydraulic thermal barrier terminal module, it flows back into the short-term cold storage module SCCS. The short-term cold storage module SCCS then sends the released medium back to the energy supplement module to replenish cold energy.

[0023] Preferably, the hydraulic thermal barrier terminal module includes a wall hydraulic thermal barrier system (TAW) and a floor hydraulic thermal barrier system (RFS), wherein the wall hydraulic thermal barrier system (TAW) is interconnected with the floor hydraulic thermal barrier system (RFS) through pipelines.

[0024] The wall hydraulic thermal barrier system TAW and the floor hydraulic thermal barrier system RFS are both connected to the short-term thermal storage body SHCS and receive the medium from the short-term thermal storage body SHCS.

[0025] The medium from the short-term thermal storage system (SHCS) enters the wall hydraulic thermal barrier system (TAW) or the floor hydraulic thermal barrier system (RFS) to release heat. After heat release, the medium flows back to the short-term thermal storage system (SHCS) to replenish the thermal energy.

[0026] After the medium from the short-term thermal storage body SHCS releases heat through the floor hydraulic thermal barrier system RFS, it enters the wall hydraulic thermal barrier system TAW for secondary heat release. The medium after secondary heat release flows back to the short-term thermal storage body SHCS to replenish thermal energy.

[0027] The wall hydraulic thermal barrier system TAW and the floor hydraulic thermal barrier system RFS are both connected to the short-term cold storage body SCCS and receive the medium from the short-term cold storage body SCCS.

[0028] The medium from the short-term cold storage SCCS enters the wall hydraulic thermal barrier system TAW or the floor hydraulic thermal barrier system RFS for cooling. After cooling, the medium flows back to the short-term cold storage SCCS to replenish the cold energy.

[0029] The medium from the short-term cold storage system (SCCS) is released into the wall hydraulic thermal barrier system (TAW) after being cooled, and then enters the floor hydraulic thermal barrier system (RFS) for secondary cooling. The medium after secondary cooling flows back into the short-term cold storage system (SCCS) to replenish the cooling energy.

[0030] Preferably, the energy supply module includes a heat pump HP and a cooling tower CT. The heat pump HP is connected to the long-term thermal storage body LHCS. The heat pump HP is used to replenish the heat of the long-term thermal storage body LHCS. After the long-term thermal storage body LHCS has completed the heat replenishment, it is transported to the short-term thermal storage body SHCS through a medium.

[0031] The cooling tower CT is connected to the long-term cold storage body LCCS. The cooling tower CT is used to replenish the cold energy of the long-term cold storage body LCCS. The heat pump HP is connected to the long-term cold storage body LCCS. The heat pump HP is used to supplement the cooling of the long-term cold storage body LCCS. After the long-term cold storage body LCCS completes the supplemental cooling, it is transported to the short-term cold storage body SCCS through a medium.

[0032] Preferably, the power storage supply module includes a renewable energy generation system RPG, an energy storage device ES, and a State Grid SG.

The State Grid SG is connected to the energy storage device ES and replenishes the energy storage device ES with electrical energy. The State Grid SG is connected to the renewable energy generation system RPG and uploads excess electrical energy to the State Grid SG.

[0033] The renewable energy power generation system RPG, energy storage device ES, and State Grid SG are all electrically connected to the thermal collector TC, short-term thermal storage SHCS, long-term thermal storage LHCS, cold collection device CC, short-term cold storage SCCS, long-term cold storage LCCS, cooling tower CT, and heat pump HP.

[0034] The renewable energy generation system RPG replenishes the energy storage device ES with electricity. After the energy storage device ES is fully replenished, the surplus energy is supplied to the national grid SG.

[0035] The renewable energy generation system RPG or energy storage device ES supplies power to the thermal collector TC, short-term thermal storage SHCS, long-term thermal storage LHCS, cooling collector CC, short-term cold storage SCCS, long-term cold storage LCCS, cooling tower CT and heat pump HP.

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments, which illustrate the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0042] Example 1:

[0043] like Figure 1 As shown in the figure, the solid arrows indicate the supply direction of cold or hot energy, and the dashed arrows indicate the return direction of cold or hot energy. This embodiment provides a three-storage and three-supply system, including a heat energy collection, storage and supply module, a cold energy collection, storage and supply module, an electricity storage and supply module, a hydraulic thermal barrier terminal module and an energy supplement module.

[0044] The thermal energy collection, storage and supply module is used to collect and store thermal energy, and the thermal energy collection, storage and supply module is connected to the hydraulic thermal barrier terminal module and supplies thermal energy to the hydraulic thermal barrier terminal module.

[0045] The cold energy collection, storage and supply module is used to collect and store cold energy. The cold energy collection, storage and supply module is connected to the hydraulic thermal barrier terminal module and supplies cold energy to the hydraulic thermal barrier terminal module.

[0046] The energy replenishment module is connected to the thermal energy collection, storage and supply module and the cold energy collection, storage and supply module respectively, and the energy replenishment module is used to replenish the thermal energy collection, storage and supply module and the cold energy collection, storage and supply module.

[0047] The thermal energy collection, storage and supply module includes a thermal collection device (TC), a short-term heat cyclic storage (SHCS), and a long-term heat cyclic storage (LHCS). The thermal collection device (TC) is installed at the heat source, the short-term heat cyclic storage (SHCS) is connected to the thermal collection device (TC), and the long-term heat cyclic storage (LHCS) is connected to the short-term heat cyclic storage (SHCS).

[0048] In the thermal storage process, the heat collection device TC collects thermal energy from the heat source. When the temperature of the thermal energy collected by the heat collection device TC is 3°C or higher than the temperature of the thermal energy stored in the short-term thermal storage body SHCS, the heat collection device TC sends the collected thermal energy to the short-term thermal storage body SHCS for storage through a medium.

[0049] When the temperature of the thermal energy stored in the short-term thermal storage body SHCS is 3°C or more higher than the temperature of the thermal energy stored in the long-term thermal storage body LHCS, the short-term thermal storage body SHCS will transfer the stored thermal energy to the long-term thermal storage body LHCS through a medium for storage.

[0050] The energy supply supplement module operates during off-peak electricity price periods. The energy supply supplement module includes a heat pump (HP), which is connected to the long-term thermal storage body (LHCS). The heat pump (HP) operates during off-peak electricity price periods to supplement thermal energy to the long-term thermal storage body (LHCS).

[0051] In the heating process, when the temperature of the thermal energy in the short-term thermal storage body SHCS meets the heating requirements, the short-term thermal storage body SHCS directly supplies thermal energy to the hydraulic thermal barrier terminal module through the medium.

[0052] When the temperature of the thermal energy stored in the short-term thermal storage body SHCS does not meet the heating requirements, the long-term thermal storage body LHCS supplies thermal energy to the short-term thermal storage body SHCS through a medium, and then the short-term thermal storage body SHCS supplies thermal energy to the hydraulic thermal barrier terminal module through a medium.

[0053] After the long-term thermal storage medium (LHCS) supplies heat energy to the short-term thermal storage medium (SHCS), its own stored heat energy decreases. The long-term thermal storage medium (LHCS) serves as the heat source for the energy supplementation module. The energy supplementation module replenishes heat to the long-term thermal storage medium (LHCS), thereby improving its quality. After replenishment, the long-term thermal storage medium (LHCS) transfers heat energy to the short-term thermal storage medium (SHCS) through a medium. The short-term thermal storage medium (SHCS) then supplies heat energy to the hydraulic thermal barrier terminal module through the medium. After the medium releases heat in the hydraulic thermal barrier terminal module, it flows back into the short-term thermal storage medium (SHCS). The short-term thermal storage medium (SHCS) then sends the medium back to the energy supplementation module to replenish heat energy.

[0054] The hydraulic thermal barrier terminal module includes a wall hydraulic thermal barrier system (TAW) and a floor hydraulic thermal barrier system (RFS). The wall hydraulic thermal barrier system (TAW) is interconnected with the floor hydraulic thermal barrier system (RFS) through pipelines.

[0055] The wall hydraulic thermal barrier system TAW and the floor hydraulic thermal barrier system RFS are both connected to the short-term thermal storage body SHCS and receive the medium from the short-term thermal storage body SHCS.

[0056] The medium from the short-term thermal storage system (SHCS) enters the wall hydraulic thermal barrier system (TAW) or the floor hydraulic thermal barrier system (RFS) to release heat according to the heating demand. After the heat is released, the medium flows back to the short-term thermal storage system (SHCS) to replenish the heat energy.

[0057] The medium from the short-term thermal storage system (SHCS) enters the floor hydraulic thermal barrier system (RFS) for heat release according to the heating demand. After heat release in the floor hydraulic thermal barrier system (RFS), it enters the wall hydraulic thermal barrier system (TAW) for secondary heat release. The medium after secondary heat release flows back to the short-term thermal storage system (SHCS) to replenish the heat energy. In the heat storage and heating processes, the medium used to transport heat energy can be heat transfer oil or water, or the appropriate liquid can be selected according to the heating temperature range.

[0058] The cold energy collection, storage and supply module includes a cold collection device (CC), a short-term cold cyclic storage (SCCS), and a long-term cold cyclic storage (LCCS). The short-term cold cyclic storage (SCCS) is connected to the cold collection device (CC), and the long-term cold cyclic storage (LCCS) is connected to the short-term cold cyclic storage (SCCS).

[0059] In the cold storage process, when the ambient temperature is 3°C or more below the temperature of the short-term cold storage body SCCS, the cold collection device CC collects cold energy from the cold source and sends the cold energy to the short-term cold storage body SCCS for storage through a medium.

[0060] When the temperature of the long-term cold storage body LCCS is 3°C or more higher than the temperature of the short-term cold storage body SCCS, the short-term cold storage body SCCS will transfer cold energy to the long-term cold storage body LCCS for storage through a medium.

[0061] The energy supply supplementation module operates during off-peak electricity price periods. The energy supply supplementation module also includes a cooling tower (CT). Both the cooling tower CT and the heat pump HP are connected to the long-term cold storage body LCCS. The cooling tower CT and the heat pump HP operate during off-peak electricity price periods to supplement the long-term cold storage body LCCS with cold energy.

[0062] In the cooling process, when the temperature of the cold energy stored in the short-term cold storage body SCCS meets the cooling requirements, the short-term cold storage body SCCS directly supplies cold energy to the hydraulic thermal barrier terminal module through the medium.

[0063] When the temperature of the cold energy stored in the short-term cold storage body SCCS does not meet the cooling requirements, the long-term cold storage body LCCS transfers cold energy to the short-term cold storage body SCCS through a medium, and then the short-term cold storage body SCCS supplies cold energy to the hydraulic thermal barrier terminal module through a medium.

[0064] After the long-term cold storage body LCCS supplies cold energy to the short-term cold storage body SCCS, the cold energy stored in it decreases. The long-term cold storage body LCCS acts as a cold source for the energy supplement module. The energy supplement module replenishes the cold energy of the long-term cold storage body LCCS, thereby improving the quality of the long-term cold storage body LCCS. After replenishment, the long-term cold storage body LCCS transfers cold energy to the short-term cold storage body SCCS through a medium. The short-term cold storage body SCCS then transfers cold energy to the hydraulic thermal barrier terminal module through a medium. After the medium is released in the hydraulic thermal barrier terminal module, it flows back into the short-term cold storage body SCCS. The short-term cold storage body SCCS then sends the medium back to the energy supplement module for replenishment of cold energy.

[0065] The wall-mounted hydraulic thermal barrier system (TAW) and the floor-mounted hydraulic thermal barrier system (RFS) in the hydraulic thermal barrier terminal module are both connected to the short-term cold storage body (SCCS) and receive the medium from the short-term cold storage body (SCCS).

[0066] The medium from the short-term cold storage SCCS enters the wall hydraulic thermal barrier system TAW or the floor hydraulic thermal barrier system RFS for cooling release according to the cooling demand. After cooling release, the medium flows back to the short-term cold storage SCCS to replenish the cooling energy.

[0067] The medium from the short-term cold storage system SCCS enters the wall hydraulic thermal barrier system TAW for cooling release according to the cooling demand. After cooling release in the wall hydraulic thermal barrier system TAW, it enters the floor hydraulic thermal barrier system RFS for secondary cooling release. After secondary cooling release, the medium flows back to the short-term cold storage system SCCS to replenish the cold energy. In the cold storage process and the cooling process, the medium used to transport cold energy can be brine, ethylene glycol and fluorinated liquid, or the corresponding liquid can be selected according to the cooling temperature range.

[0068] The power storage and supply module includes a Renewable Energy Power Generation System (RPG), an Energy Storage Device (ES), and a State Grid (SG). The RPG generates electricity, the ES is connected to the RPG and stores electrical energy, the SG is connected to the ES and replenishes the ES with electrical energy, and the RPG uploads excess electrical energy to the SG.

[0069] The renewable energy power generation system RPG, energy storage device ES, and State Grid SG are all electrically connected to the thermal collector TC, short-term thermal storage SHCS, long-term thermal storage LHCS, cold collection device CC, short-term cold storage SCCS, long-term cold storage LCCS, cooling tower CT, and heat pump HP.

[0070] The renewable energy generation system RPG replenishes the energy storage device ES with electricity. After the energy storage device ES is fully replenished, the surplus energy is supplied to the national grid SG.

[0071] The renewable energy generation system RPG or energy storage device ES supplies power to the thermal collector TC, short-term thermal storage SHCS, long-term thermal storage LHCS, cooling collector CC, short-term cold storage SCCS, long-term cold storage LCCS, cooling tower CT and heat pump HP.

[0072] State Grid SG stores electricity in energy storage device ES, and State Grid SG directly supplies power to thermal collector TC, short-term thermal storage SHCS, long-term thermal storage LHCS, cold collection device CC, short-term cold storage SCCS, long-term cold storage LCCS, cooling tower CT and heat pump HP.

[0073] Operation control method:

[0074] During the cooling season heat storage process, the heat collection device TC collects heat energy from the heat source. When the temperature of the heat collection device TC is 3°C or higher than that of the short-term heat storage body SHCS, the heat collection device TC will send the collected heat energy to the short-term heat storage body SHCS for storage.

[0075] When the temperature of the short-term thermal storage SHCS is 3°C or higher than that of the long-term thermal storage LHCS, the short-term thermal storage SHCS will transfer the stored thermal energy to the long-term thermal storage LHCS for storage.

[0076] The energy replenishment module replenishes the thermal energy in the long-term thermal storage body LHCS during off-peak electricity price periods.

[0077] In the direct heating process during the heating season, when the thermal energy in the short-term thermal storage body SHCS meets the heating requirements, the short-term thermal storage body SHCS directly supplies thermal energy to the hydraulic thermal barrier terminal module.

[0078] When the thermal energy stored in the short-term thermal storage SHCS does not meet the heating requirements, the long-term thermal storage LHCS supplies thermal energy to the short-term thermal storage SHCS, and then the short-term thermal storage SHCS supplies thermal energy to the hydraulic thermal barrier terminal module.

[0079] In the auxiliary heating process during the heating season, when the heat stored in the long-term thermal storage body (LHCS) has completed heating and cooled down, the long-term thermal storage body (LHCS) sends the heat to the energy replenishment module to replenish the energy. After replenishment, the heat is transferred from the energy replenishment module to the short-term thermal storage body (SHCS). The short-term thermal storage body (SHCS) supplies heat to the hydraulic thermal barrier terminal module. After the heat is heated and cooled down in the hydraulic thermal barrier terminal module, it flows back to the short-term thermal storage body (SHCS). The short-term thermal storage body (SHCS) sends the cooled heat back to the energy replenishment module for replenishment.

[0080] The heat energy from the short-term thermal storage system (SHCS) is selected to be separately fed into the wall hydraulic thermal barrier system (TAW) or the floor hydraulic thermal barrier system (RFS) for heat energy utilization. After the heat energy utilization is completed, it flows back from the wall hydraulic thermal barrier system (TAW) or the floor hydraulic thermal barrier system (RFS) to the short-term thermal storage system (SHCS) for replenishment. Alternatively, the heat energy from the short-term thermal storage system (SHCS) can be selected to first be utilized by the floor hydraulic thermal barrier system (RFS), and then enter the wall hydraulic thermal barrier system (TAW) for secondary heat energy utilization through pipelines. After the secondary heat energy utilization is completed, the heat energy flows back to the short-term thermal storage system (SHCS) for replenishment.

[0081] During the cold storage process in the heating season, when the ambient temperature is 3 degrees Celsius lower than the temperature of the short-term cold storage body SCCS, the cold collection device CC collects cold energy and sends the cold energy to the short-term cold storage body SCCS for storage.

[0082] When the temperature of the long-term cold storage body LCCS is higher than the temperature of the short-term cold storage body SCCS, the short-term cold storage body SCCS will transfer cold energy to the long-term cold storage body LCCS for storage.

[0083] The power supply module replenishes and cools the long-term cold storage LCCS during off-peak electricity price periods.

[0084] In the direct cooling process during the cooling season, when the cold energy stored in the short-term cold storage SCCS meets the energy supply requirements, the short-term cold storage SCCS directly supplies cold energy to the hydraulic thermal barrier terminal module.

[0085] When the cold energy stored in the short-term cold storage SCCS is insufficient to meet the cooling requirements, the long-term cold storage LCCS transfers cold energy to the short-term cold storage SCCS, and the short-term cold storage SCCS supplies cold energy to the hydraulic thermal barrier terminal module.

[0086] In the cooling season, when the long-term cold storage LCCS completes the cooling and the temperature rises, the cold energy collection, storage and supply module sends the cold energy to the energy replenishment module to replenish the energy. After replenishment, the cold energy is sent from the energy replenishment module to the short-term cold storage SCCS. The short-term cold storage SCCS sends the cold energy to the hydraulic thermal barrier terminal module. After the cold energy completes the cooling and temperature rise in the hydraulic thermal barrier terminal module, it flows back to the short-term cold storage SCCS. The short-term cold storage SCCS sends the heated cold energy back to the energy replenishment module for replenishment.

[0087] The cold energy from the short-term cold storage system SCCS is selected to enter the wall hydraulic thermal barrier system TAW or the floor hydraulic thermal barrier system RFS for cold energy utilization. After the cold energy utilization is completed, it flows back from the wall hydraulic thermal barrier system TAW or the floor hydraulic thermal barrier system RFS to the short-term cold storage system SCCS for replenishment. Alternatively, the cold energy from the short-term cold storage system SCCS can be selected to first pass through the wall hydraulic thermal barrier system TAW for cold energy utilization, and then enter the floor hydraulic thermal barrier system RFS through the pipeline for secondary cold energy utilization. After the secondary cold energy utilization is completed, the cold energy flows back to the short-term cold storage system SCCS for replenishment.

[0088] In the energy storage process, the renewable energy generation system RPG replenishes the energy storage device ES with electricity. After the energy storage device ES is fully replenished, the surplus energy is supplied to the national grid SG.

[0089] In the power supply process, the power storage supply module supplies power to the thermal collector TC, short-term thermal storage SHCS, long-term thermal storage LHCS, cold collection device CC, short-term cold storage SCCS, long-term cold storage LCCS, cooling tower CT, and heat pump HP.

[0090] During off-peak electricity price periods, State Grid SG supplies power to the energy storage device ES, and State Grid SG directly supplies power to the thermal collector TC, short-term thermal storage SHCS, long-term thermal storage LHCS, cold storage device CC, short-term cold storage SCCS, long-term cold storage LCCS, cooling tower CT, and heat pump HP.

[0091] Example 2:

[0092] like Figure 2 As shown, the operation control process of the three-storage and three-supply system in this embodiment is as follows:

[0093] During the heat storage phase of the cooling season, when the temperature of the heat collection device TC is 3°C or higher than that of the short-term heat storage body SHCS, valves WP1 and V1, valves WP2 and V2 between the heat collection device TC and the short-term heat storage body SHCS are opened in sequence. At this time, the heat collection device TC and the short-term heat storage body SHCS are connected, and the heat collection device TC sends the collected heat energy to the short-term heat storage body SHCS for storage.

[0094] When the temperature of the short-term thermal storage SHCS is 3°C or more higher than that of the long-term thermal storage LHCS, valves WP3, V5, V9, WP4, V10, V13, and V6 between the short-term thermal storage SHCS and the long-term thermal storage LHCS are opened in sequence. At this time, the short-term thermal storage SHCS and the long-term thermal storage LHCS are connected. The short-term thermal storage SHCS sends the stored thermal energy to the long-term thermal storage LHCS for storage. The thermal energy circulates between the short-term thermal storage SHCS and the long-term thermal storage LHCS.
