[0023] The present application provides a cold and hot dual storage and dual supply system, which combines Figure 1As shown, the dual-storage and dual-supply system for both cooling and heating specifically includes: an energy conversion unit, an energy storage unit, and an energy release unit. The energy conversion unit includes an ice slurry heat pump 1 and an ice maker 2; the energy storage unit includes an energy storage tank 3; the energy release unit includes a heat exchanger 4; the cold end of the ice slurry heat pump 1 is connected to the cooling side of the ice maker 2 via a first pipe 18 to form a circulation loop; a refrigerant flows within the first pipe 18. The charging side of the energy storage tank 3 is connected to the water side of the ice maker 2 via a second pipe 19 to form a cooling storage loop; the charging side of the energy storage tank 3 is connected to the hot end of the ice slurry heat pump 1 via a third pipe 20 to form a heating storage loop; the energy release side of the energy storage tank 3 is connected to one side of the heat exchanger 4 via a fourth pipe 21 to form an energy release loop; the other side of the heat exchanger 4 is used to connect to a user terminal 5 to achieve cooling or heating. The energy conversion unit is configured such that when the energy storage tank 3 stores cold energy, the ice slurry heat pump 1 provides cooling capacity to the ice maker 2, i.e., the cooling capacity generated at the cold end of the ice slurry heat pump 1 is circulated to the ice maker 2 via a refrigerant. When the energy storage tank 3 stores heat energy, the ice maker 2 provides heat energy to the ice slurry heat pump 1. It should be noted that the aforementioned heat energy comes from a low-temperature heat source, i.e., the ice maker 2 exchanges heat with an external water source through the refrigerant flowing through it to extract the sensible and latent heat of the external water source. All the extracted heat energy is circulated to the cold end of the ice slurry heat pump 1 via the refrigerant, thereby providing the ice slurry heat pump 1 with a stable heat source. Low temperature refers to the temperature relative to the heating temperature required by the user end. The heat exchanger 4 is an energy-releasing plate heat exchanger, whose function is to efficiently transfer the cold or heat energy stored in the energy storage tank 3 to the circulating fluid of the user end 5, thereby providing air conditioning or heating for the user end 5. Using an ice slurry heat pump 1 as the source of cold and heat energy, dual storage and dual supply of cold and heat are achieved through switching between different pipelines. Furthermore, the cold and hot ends of the ice slurry heat pump 1, the cooling and water sides of the ice maker 2, the charging and discharging sides of the energy storage tank 3, and both sides of the heat exchanger 4 all include interfaces for connecting pipelines. The cold end interface of the ice slurry heat pump 1 is connected to the cooling side interface of the ice maker 2 via a pipeline, and the hot end interface of the ice slurry heat pump 1 is connected to the charging side interface of the energy storage tank 3 via a pipeline. The charging side interface of the energy storage tank 3 is connected to the water side interface of the ice maker 2 via a pipeline, and the discharging side interface of the energy storage tank 3 is connected to one side interface of the heat exchanger 4 via a pipeline. The other side interface of the heat exchanger 4 is connected to the user terminal 5 via a pipeline. The user terminal 5 refers to the air conditioning equipment within the building that provides cooling and heating to users. Figure 1 As shown, the left side of the ice slurry heat pump 1 is the hot end, and the right side is the cold end. The left side of the ice maker 2 is the cooling side, and the right side is the water side. The left side of the energy storage tank 3 is the charging side, and the right side is the discharging side. The left side of the heat exchanger 4 is the other side, and the right side is one side. Figure 1 The arrows on the central pipeline indicate the direction of fluid flow within the pipeline.

[0024] In a specific embodiment, the first pipeline 18 contains a coolant, and a first coolant pump 9 is arranged on the first pipeline 18; the first coolant pump 9 is used to drive the coolant to circulate between the cold end of the ice slurry heat pump 1 and the coolant side of the ice maker 2. When the energy storage tank 3 stores cold energy, the coolant acts as a cold energy carrier, absorbs cold energy when flowing through the cold end of the ice slurry heat pump 1, and then flows to the coolant side of the ice maker 2 to complete the delivery of cold energy. When the energy storage tank 3 stores heat energy, the coolant acts as a low-temperature heat source carrier, absorbs the sensible heat and latent heat extracted from the external water source when flowing through the coolant side of the ice maker 2, and then flows to the cold end of the ice slurry heat pump 1 to release the heat carried to the ice slurry heat pump 1, completing the delivery of low-temperature heat source.

[0025] In a specific embodiment, the energy storage tank 3 is used to store water, and stores ice slurry generated by the ice maker 2 in the cold storage mode and stores hot water heated by the hot end of the ice slurry heat pump 1 in the heat storage mode. The cold storage mode and the heat storage mode respectively refer to two working states in which the energy storage tank 3 needs to store cold energy and heat energy. Further, the energy storage unit further comprises an energy storage pump 12 arranged on the energy storage tank 3 on the energy storage side; the energy storage pump 12 is connected with the second pipeline 19 and the third pipeline 20; the first energy storage valve 10 is arranged on the second pipeline 19, and the flow direction of water in the energy storage tank 3 to the ice maker 2 and back to storage as ice slurry is controlled through the first energy storage valve 10 and the energy storage pump 12; the second energy storage valve 11 is arranged on the third pipeline 20, and the flow direction of water in the energy storage tank 3 to the hot end of the ice slurry heat pump 1 and back to storage as hot water is controlled through the second energy storage valve 11 and the energy storage pump 12.

[0026] In a specific embodiment, the energy release unit further comprises an energy release valve 14 and an energy release pump 13 arranged on the fourth pipeline 21, which are used to control the flow direction of ice slurry or hot water in the energy storage tank 3 to the heat exchanger 4 to release energy and exchange heat with the user end 5. Through the above arrangement, the ice slurry or hot water transfers the cold energy or heat energy contained therein to the user end 5 through the heat exchanger 4, thereby realizing cooling or heating. Further, a circulation loop is formed between the heat exchanger 4 and the user end 5 through the fifth pipeline 22; the second coolant pump 25 is arranged on the fifth pipeline 22, which is used to drive the circulating fluid of the user end 5 to circulate between the heat exchanger 4 and the user end 5, realizing the exchange of cold energy or heat energy.

[0027] In a specific embodiment, the cold-heat dual storage and dual supply system further comprises a water source unit, the water source unit comprising a water source pump 8, a first water source valve 6 and a second water source valve 7; the first water source valve 6 being connected between the water source pump 8 and the hot end of the ice slurry heat pump 1, for dissipating heat for the ice slurry heat pump 1 in the cold storage mode; the second water source valve 7 being connected between the water source pump 8 and the water side of the ice making host 2, for providing external water source for the ice making host 2 in the heat storage mode. Further, the water source pump 8 is connected with the hot end of the ice slurry heat pump 1 through a first water source pipeline 23, and the water source pump 8 is connected with the water side of the ice making host 2 through a second water source pipeline 24. The first water source valve 6 is arranged on the first water source pipeline 23, and the second water source valve 7 is arranged on the second water source pipeline 24. The external water source flows through the ice slurry heat pump 1 and the ice making host 2 under the driving of the water source pump 8 and is discharged through a drain port 17. Specifically, the external water source flows through the hot end of the ice slurry heat pump 1 under the driving of the water source pump 8, absorbs and carries away the heat generated during the operation of the ice slurry heat pump 1 as a heat sink, and is discharged out of the system through the drain port 17, thereby ensuring efficient refrigeration of the ice slurry heat pump 1. The external water source flows through the water side of the ice making host 2 under the driving of the water source pump 8, releases sensible heat and latent heat therein, and is discharged out of the system through the drain port 17.

[0028] In order to maintain the necessary amount of water in the energy storage tank 3 and ensure the continuous energy storage and release capacity, a water supplement pipe for supplementing water into the energy storage tank 3 is connected to the energy storage tank 3; a water supplement valve 15 is arranged on the water supplement pipe.

[0029] The working process of the present application is as follows: in the cold storage and cooling process, the external water source flows through the hot end of the ice slurry heat pump 1 to dissipate heat for the ice slurry heat pump 1, the ice slurry heat pump 1 provides cold energy to the ice making host 2 to generate ice slurry and store in the energy storage tank 3, and the stored ice slurry provides cold energy to the user end 5 through the heat exchanger 4. In the heat storage and heating process, the external water source flows through the ice making host 2 to release heat, the ice making host 2 provides a low-temperature heat source to the ice slurry heat pump 1, the ice slurry heat pump 1 heats the water from the energy storage tank 3 and stores it as hot water, and the stored hot water provides heat to the user end 5 through the heat exchanger 4.

[0030] Specifically, the cold storage and cooling process: open the first water source valve 6 and the first charging valve 10, close the second water source valve 7 and the second charging valve 11; the external water source flows through the ice slurry heat pump 1 heat end to dissipate heat, and the cold energy generated by the ice slurry heat pump 1 cold end is transported to the ice maker 2 through the refrigerant; the water in the energy storage tank 3 is transported to the ice maker 2 to be cooled into ice slurry and then returned to storage; when the user needs cooling, the stored ice slurry is pumped to the heat exchanger 4, and after heat exchange with the circulating fluid of the user end 5, it returns to the energy storage tank 3. The heat storage and heating process: close the first water source valve 6 and the first charging valve 10, open the second water source valve 7 and the second charging valve 11; the external water source flows through the ice maker 2, releases sensible heat and latent heat, and then is discharged; the released heat is transported to the ice slurry heat pump 1 cold end through the refrigerant as a low-temperature heat source; the water in the energy storage tank 3 is transported to the ice slurry heat pump 1 heat end to be heated into hot water and then returned to storage; when the user needs heating, the stored hot water is pumped to the heat exchanger 4, and after heat exchange with the circulating fluid of the user end 5, it returns to the energy storage tank 3. More specifically, in summer, the first water source valve 6 is opened, the second water source valve 7 is closed, and the external water entering from the water inlet 16 is driven by the water source pump 8 to enter the ice slurry heat pump 1 heat end through the first water source valve 6, and then is discharged from the water outlet 17 after carrying the heat dissipation of the heat pump. At the same time, the cold energy of the ice slurry heat pump 1 cold end is circulated through the refrigerant to provide cold energy for the ice maker 2. The first charging valve 10 is opened, the second charging valve 11 is closed, the water in the energy storage tank 3 is driven by the energy storage pump 12 to enter the ice maker 2 through the first charging valve 10, and then returns to the energy storage tank 3 after being cooled to produce ice slurry, realizing ice slurry cold storage. When the user needs cold energy, the stored ice slurry is driven by the energy release pump 13 to enter the energy release plate heat exchanger through the energy release valve 14, and exchanges energy with the cold water from the user end 5, and the temperature of the cold water of the user end 5 is reduced. In winter, the first water source valve 6 is closed, the second water source valve 7 is opened, and the external water entering from the water inlet 16 is driven by the water source pump 8 to enter the ice maker 2 through the second water source valve 7, and then is discharged from the water outlet 17 after the sensible heat and latent heat of the water are extracted. At the same time, the heat extracted by the ice maker 2 is circulated through the refrigerant to provide a low-temperature heat source for the ice slurry heat pump 1. The first charging valve 10 is closed, the second charging valve 11 is opened, the water in the energy storage tank 3 is driven by the energy storage pump 12 to enter the ice slurry heat pump 1 heat end through the second charging valve 11, and then returns to the energy storage tank 3 after the water temperature is increased, realizing sensible heat storage of hot water. When the user needs heat, the stored high-temperature hot water is driven by the energy release pump 13 to enter the energy release plate heat exchanger through the energy release valve 14, and exchanges energy with the hot water from the user end 5, and the temperature of the hot water of the user end 5 is increased.

The application uses water as an energy storage medium, stores cold energy in the energy storage tank by ice slurry in summer, stores heat energy in the energy storage tank by sensible heat in winter, and is matched with the same set of ice slurry heat pump and ice making host, so that the function conversion can be realized only by pipeline switching, and the system has high integration. This fundamentally solves the problems of high equipment investment, large floor area and complex system caused by the independent cold storage and heat storage systems in the traditional scheme. When the system runs in winter, the ice making host fully extracts sensible heat and latent heat from an external water source to provide a low-temperature heat source for the ice slurry heat pump, so that the ice slurry heat pump can still maintain good heating performance in the cold season. Therefore, efficient winter heating is realized, and the comprehensive energy efficiency of the system is improved.
