[0127] The three ports of the seventh three-way valve 53 are respectively connected to the first port of the water pipeline of the second heat exchanger 4, the first port of the second pipeline 111 of the cold storage device 10, and the first port of the second pipeline 114 of the heat storage device 12.

[0128] The three ports of the eighth three-way valve 56 are respectively connected to the second port of the water pipeline of the second heat exchanger 4, the second port of the second pipeline 111 of the cold storage device 10, and the second port of the second pipeline 114 of the heat storage device 12.

[0129] In some embodiments, the third valve assembly can also be implemented by a two-way valve.

[0130] As Figure 2 、 3 shown, the first valve group has a state where the refrigerant heat exchanger 1 is in communication with the refrigerant pipeline and the second heat exchanger 4 is cut off from the refrigerant pipeline; the second valve group has a state where the heat dissipation heat exchanger 13 is in communication with the first heat exchanger 9, and the first pipeline 116 of the heat storage device 12 and the first pipeline 113 of the cold storage device 10 are cut off from the first heat exchanger 9; the third valve group has a state where the second pipeline 114 of the heat storage device 12 and the second pipeline 111 of the cold storage device 10 are cut off from the second heat exchanger 4.

[0131] The state of the first valve group makes the refrigerant heat exchanger 1 connected to the refrigerant circulation system, and the second heat exchanger 4 is not connected to the refrigerant circulation system. The state of the second valve group makes the heat dissipation heat exchanger 13 connected to the energy storage circulation system, and the first pipeline 116 of the heat storage device 12 and the first pipeline 113 of the cold storage device 10 are not connected to the energy storage circulation system. The state of the third valve group makes the second pipeline 114 of the heat storage device 12 and the second pipeline 111 of the cold storage device 10 are not connected to the energy storage circulation system. Therefore, when the compressor 6 is running, the ordinary heating function of the heat dissipation heat exchanger 13 or the ordinary cooling function of the heat dissipation heat exchanger 13 can be realized by switching the four-way valve 8.

[0132] like Figure 2 The diagram shown is a diagram of a typical heating cycle, with arrowed lines representing the circulation loop. Four-way valve 8 is switched to heating mode, and the first heat exchanger 9 functions as a condenser. Refrigerant flows from compressor 6, enters and exits four-way valve 8, then enters the first heat exchanger 9 to heat the circulating water. After passing through throttling element 7 and second three-way valve 52, it enters refrigerant heat exchanger 1 for heat exchange with the external environment. After this, it flows back to compressor 6 through first three-way valve 51 and four-way valve 8. The circulating water heated by the first heat exchanger 9 enters heat exchanger 13 through first pump 32, third three-way valve 54, and fourth three-way valve 55 for heat exchange. After the heat exchange is complete, the circulating water enters the first heat exchanger 9 through sixth three-way valve 58 and fifth three-way valve 57 to begin the next heat exchange cycle. This achieves independent heating of heat exchanger 13.

[0133] like Figure 3 The diagram shown is a diagram of a typical refrigeration cycle, with arrowed lines representing circulation loops. The four-way valve 8 is switched to cooling mode, and the first heat exchanger 9 serves as the evaporator. Refrigerant flows from the compressor 6 into and out of the four-way valve 8, then enters the refrigerant heat exchanger 1 through the first three-way valve 51 for heat exchange with the external environment. After throttling through the second three-way valve 52, it enters the throttling element 7 and enters the first heat exchanger 9 to cool the circulating water. The water then flows back to the compressor 6 through the four-way valve 8. The circulating water cooled by the first heat exchanger 9 passes through the first pump body 32, the third three-way valve 54, and the fourth three-way valve 55 to enter the heat dissipation heat exchanger 13 for heat exchange. After the heat exchange is complete, the circulating water enters the first heat exchanger 9 through the sixth three-way valve 58 and the fifth three-way valve 57 to begin the next heat exchange cycle. This achieves independent cooling of the heat dissipation heat exchanger 13.

[0135] The state of the first valve group enables the refrigerant heat exchanger 1 to be connected to the refrigerant circulation system, the second heat exchanger 4 is not connected to the refrigerant circulation system, the state of the second valve group enables the heat dissipation heat exchanger 13 not to be connected to the energy storage circulation system, the first pipeline 116 of the heat storage device 12 or the first pipeline 113 of the cold storage device 10 is connected to the energy storage circulation system, and the state of the third valve group enables both the second pipeline 114 of the heat storage device 12 and the second pipeline 111 of the cold storage device 10 not to be connected to the energy storage circulation system. Therefore, when the compressor 6 operates, by switching the four-way valve 8, the ordinary heat storage function of the heat storage device 12 for heat storage or the ordinary cold storage function of the cold storage device 10 for cold storage can be realized.

[0136] As Figure 4 shown, it is a diagram of an ordinary heat storage cycle, and the connecting lines with arrows are the circulation loops. The four-way valve 8 is switched to the heating state, the first heat exchanger 9 is a condenser, the refrigerant flows out of the compressor 6 and enters the four-way valve 8, and then enters the first heat exchanger 9 to heat the circulating water. After passing through the throttling element 7, it enters the refrigerant heat exchanger 1 through the second three-way valve 52, exchanges heat with the external environment, and then flows back to the compressor 6 through the first three-way valve 51 and the four-way valve 8. The circulating water heated by the first heat exchanger 9 enters the first pipeline 116 in the heat storage device 12 through the first pump body 32, the third three-way valve 54 and the fourth three-way valve 55 for heat exchange. After the heat exchange is completed, the circulating water enters the first heat exchanger 9 through the sixth three-way valve 58 and the fifth three-way valve 57 to start the next heat exchange cycle. The separate heat storage of the heat storage device 12 is realized.

[0137] Domestic water flows through the heat exchange pipeline 115 in the heat storage device 12 to realize instant hot water supply.

[0138] As Figure 5 shown, it is a diagram of an ordinary cold storage cycle, and the connecting lines with arrows are the circulation loops. The four-way valve 8 is switched to the cooling state, the first heat exchanger 9 is an evaporator, the refrigerant flows out of the compressor 6 and enters the four-way valve 8, and then enters the refrigerant heat exchanger 1 through the first three-way valve 51, exchanges heat with the external environment, enters the throttling element 7 through the second three-way valve 52 for throttling, then enters the first heat exchanger 9 to cool the circulating water, and then flows back to the compressor 6 through the four-way valve 8. The circulating water cooled by the first heat exchanger 9 enters the first pipeline 113 of the cold storage device 10 through the first pump body 32 and the third three-way valve 54 for heat exchange. After the heat exchange is completed, the circulating water enters the first heat exchanger 9 through the fifth three-way valve 57 to start the next heat exchange cycle. The separate cold storage of the cold storage device 10 is realized.

[0139] Domestic water flows through the cold exchange pipeline 112 in the cold storage device 10 to realize instant cold water supply.

[0140] As Figure 6 、 7As shown, the first valve group has a state where the refrigerant heat exchanger 1 is cut off from the refrigerant pipeline and the second heat exchanger 4 is connected to the refrigerant pipeline; the second valve group has a state where the first pipeline 116 of the heat storage device 12 is cut off from the first heat exchanger 9, the first pipeline 113 of the cold storage device 10 is cut off from the first heat exchanger 9, and the heat dissipation heat exchanger 13 is connected to the first heat exchanger 9; the third valve group has a state where the second pipeline 114 of the heat storage device 12 or the second pipeline 111 of the cold storage device 10 is connected to the second heat exchanger 4.

[0141] The state of the first valve group makes the refrigerant heat exchanger 1 not connected to the refrigerant circulation system, and the second heat exchanger 4 is connected to the refrigerant circulation system. The state of the second valve group makes the heat dissipation heat exchanger 13 connected to the energy storage circulation system, and the first pipeline 116 of the heat storage device 12 and the first pipeline 113 of the cold storage device 10 are not connected to the energy storage circulation system. The state of the third valve group makes the second pipeline 114 of the heat storage device 12 or the second pipeline 111 of the cold storage device 10 connected to the energy storage circulation system. Therefore, when the compressor 6 is running, by switching the four-way valve 8, the heating and cold storage functions of heating the heat dissipation heat exchanger 13 and storing cold in the cold storage device 10 or the refrigeration and heat storage functions of cooling the heat dissipation heat exchanger 13 and storing heat in the heat storage device 12 can be achieved.

[0142] As Figure 6 shown, it is a heating and cold storage cycle diagram, and the connecting lines with arrows are the cycle circuits. The four-way valve 8 is switched to the heating state, the first heat exchanger 9 is the condenser, the refrigerant flows out of the compressor 6 and enters the four-way valve 8, and then enters the first heat exchanger 9 to heat the circulating water. After passing through the throttling element 7, it enters the second heat exchanger 4 through the second three-way valve 52 to cool the circulating water. The refrigerant that absorbs the heat of the circulating water returns to the compressor 6 through the first three-way valve 51 and the four-way valve 8 to start the next cycle. The circulating water heated by the first heat exchanger 9 enters the heat dissipation heat exchanger 13 through the first pump body 32, the third three-way valve 54 and the fourth three-way valve 55 for heat exchange. After the heat exchange is completed, the circulating water enters the first heat exchanger 9 through the sixth three-way valve 58 and the fifth three-way valve 57 to start the next heat exchange cycle. Another path of circulating water is cooled by the second heat exchanger 4 and then flows through the second pipeline 111 in the cold storage device 10, and flows through the eighth three-way valve 56 and returns to the second heat exchanger 4 through the second pump body 31 for further cooling. The heating of the heat dissipation heat exchanger 13 and the cold storage of the cold storage device 10 are realized.

[0143] Domestic water flows through the cold exchange pipeline 112 in the cold storage device 10 to achieve instant cold water output.

[0144] As Figure 7The diagram shows a cooling and thermal storage cycle, with arrowed lines representing the circulation loop. Four-way valve 8 is switched to cooling mode, and the first heat exchanger 9 functions as an evaporator. Refrigerant flows from compressor 6 into and out of four-way valve 8, then passes through first three-way valve 51 to enter the second heat exchanger 4, where it heats the circulating water. After throttling through second three-way valve 52, it enters throttling element 7, enters the first heat exchanger 9, where it cools the circulating water. The water then flows back through four-way valve 8 to compressor 6. The cooled circulating water in the first heat exchanger 9 then passes through first pump 32, third three-way valve 54, and fourth three-way valve 55 to enter heat exchanger 13 for heat exchange. After heat exchange, the water passes through sixth and fifth three-way valves 58 and 57 to enter the first heat exchanger 9 for the next heat exchange cycle. Another circuit of circulating water, heated in the second heat exchanger 4, flows through seventh three-way valve 53, flows through second pipeline 114 within thermal storage device 12, passes through eighth three-way valve 56, and returns to the second pump 31 for further heating. The cooling of the heat exchanger 13 and the heat storage of the heat storage device 12 are achieved.

[0145] Domestic water flows through the heat exchange pipe 115 in the phase change heat storage device 12 to produce hot water.

[0146] like Figure 8 As shown, the first valve group has a state in which the refrigerant heat exchanger 1 and the refrigerant pipeline are cut off, and the second heat exchanger 4 and the refrigerant pipeline are connected; the second valve group has a state in which the first pipeline 116 of the heat storage device 12 and the first heat exchanger 9 are connected, and the first pipeline 113 of the cold storage device 10, the heat dissipation heat exchanger 13 and the first heat exchanger 9 are cut off; the third valve group has a state in which the second pipeline 114 of the heat storage device 12 and the second heat exchanger 4 are cut off, and the second pipeline 111 of the cold storage device 10 and the second heat exchanger 4 are connected.

[0147] The state of the first valve group makes the refrigerant heat exchanger 1 not connected to the refrigerant circulation system, the second heat exchanger 4 is connected to the refrigerant circulation system, the state of the second valve group makes the heat dissipation heat exchanger 13 not connected to the energy storage circulation system, the first pipeline 116 of the heat storage device 12 is connected to the energy storage circulation system, the first pipeline 113 of the cold storage device 10 is not connected to the energy storage circulation system, the state of the third valve group makes the second pipeline 114 of the heat storage device 12 not connected to the energy storage circulation system, and the second pipeline 111 of the cold storage device 10 is connected to the energy storage circulation system. Therefore, when the compressor 6 is running, the cold storage and heat storage functions of the cold storage device 10 and the heat storage device 12 can be realized.

[0148] like Figure 8As shown in the figure, it is a diagram of the cold storage and heat storage cycle. The connecting line with an arrow is the cycle loop. The four-way valve 8 is switched to the refrigeration state. The first heat exchanger 9 is an evaporator. The refrigerant flows out of the compressor 6, enters the four-way valve 8, then enters the second heat exchanger 4 through the first three-way valve 51 to heat the circulating water, and then enters the throttling element 7 through the second three-way valve 52 for throttling, and then enters the first heat exchanger 9 to cool the circulating water, and then flows back to the compressor 6 through the four-way valve 8. The circulating water cooled by the first heat exchanger 9 enters the first pipeline 116 of the heat storage device 12 through the first pump body 32, the third three-way valve 54 and the fourth three-way valve 55 for heat exchange. After the heat exchange is completed, the circulating water enters the first heat exchanger 9 through the sixth three-way valve 58 and the fifth three-way valve 57 to start the next heat exchange cycle. Another path of circulating water is heated by the second heat exchanger 4 and then flows through the seventh three-way valve 53 through the second pipeline 111 in the cold storage device 10, and flows through the eighth three-way valve 56 and returns to the second heat exchanger 4 through the second pump body 31 for re-heating. The heat storage of the heat storage device 12 and the cold storage of the cold storage device 10 are realized.

[0149] The domestic water flows through the heat exchange pipeline 115 in the heat storage device 12 to realize the immediate supply of hot water. The domestic water flows through the cold exchange pipeline 112 in the cold storage device 10 to realize the immediate supply of cold water.

[0150] As Figure 9 、 10 As shown in the figure, the first valve group has a state in which the refrigerant heat exchanger 1 is in communication with the refrigerant pipeline and the second heat exchanger 4 is cut off from the refrigerant pipeline; the second valve group has a state in which the heat dissipation heat exchanger 13 is in communication with the first heat exchanger 9, and the first pipeline 116 of the heat storage device 12 or the first pipeline 113 of the cold storage device 10 is in communication with the first heat exchanger 9; the third valve group has a state in which the second pipeline 114 of the heat storage device 12 and the second pipeline 111 of the cold storage device 10 are cut off from the second heat exchanger 4.

[0151] The state of the first valve group enables the refrigerant heat exchanger 1 to be connected to the refrigerant circulation system, and the second heat exchanger 4 is not connected to the refrigerant circulation system. The state of the second valve group enables the heat dissipation heat exchanger 13 to be connected to the energy storage circulation system, and the first pipeline 116 of the heat storage device 12 or the first pipeline 113 of the cold storage device 10 is connected to the energy storage circulation system. The state of the third valve group enables the second pipeline 114 of the heat storage device 12 and the second pipeline 111 of the cold storage device 10 not to be connected to the energy storage circulation system. Therefore, when the compressor 6 is running, by switching the four-way valve 8, the heating and heat storage function of the heat dissipation heat exchanger 13 for heating and the heat storage device 12 for heat storage or the cooling and cold storage function of the heat dissipation heat exchanger 13 for cooling and the cold storage device 10 for cold storage can be realized.

[0152] As Figure 9As shown in the figure, it is a heating and heat storage cycle diagram, and the connecting line with arrows is the cycle loop. The four-way valve 8 is switched to the heating state, and the first heat exchanger 9 is the condenser. The refrigerant flows out of the compressor 6, enters and exits the four-way valve 8, and then enters the first heat exchanger 9 to heat the circulating water. After passing through the throttling element 7, it enters the refrigerant heat exchanger 1 through the second three-way valve 52 to exchange heat with the external environment. After the heat exchange is completed, the refrigerant returns to the compressor 6 through the first three-way valve 51 and the four-way valve 8 to start the next cycle. The circulating water heated by the first heat exchanger 9 is divided into two paths through the first pump body 32, the third three-way valve 54, and the fourth three-way valve 55, and enters the heat dissipation heat exchanger 13 and the first pipeline 116 of the heat storage device 12 respectively for heat exchange. After the heat exchange is completed, the circulating water enters the first heat exchanger 9 through the sixth three-way valve 58 and the fifth three-way valve 57 to start the next heat exchange cycle. The heating of the heat dissipation heat exchanger 13 and the heat storage of the heat storage device 12 are realized.

[0153] The domestic water flows through the heat exchange pipeline 115 in the heat storage device 12 to realize the immediate supply of hot water.

[0154] As Figure 10 Shown in the figure, it is a refrigeration and cold storage cycle diagram, and the connecting line with arrows is the cycle loop. The four-way valve 8 is switched to the refrigeration state, and the first heat exchanger 9 is the evaporator. The refrigerant flows out of the compressor 6, enters and exits the four-way valve 8, and then enters the refrigerant heat exchanger 1 through the first three-way valve 51 to exchange heat with the external environment, and then enters the throttling element 7 through the second three-way valve 52 for throttling and then enters the first heat exchanger 9 to cool the circulating water, and then flows back to the compressor 6 through the four-way valve 8. The circulating water cooled by the first heat exchanger 9 is divided into two paths through the first pump body 32 and the third three-way valve 54. One path enters the first pipeline 113 of the cold storage device 10 and then returns to the first heat exchanger 9 through the fifth three-way valve 57 for heat exchange again. The other path enters the heat dissipation heat exchanger 13 through the fourth three-way valve 55 for heat exchange. After the heat exchange is completed, the circulating water enters the first heat exchanger 9 through the sixth three-way valve 58 and the fifth three-way valve 57 to start the next heat exchange cycle. The refrigeration of the heat dissipation heat exchanger 13 and the cold storage of the cold storage device 10 are realized.

[0155] The domestic water flows through the first pipeline 113 in the phase change cold storage device 10 to realize the immediate supply of cold water.

[0156] As Figure 11 Shown in the figure, when the refrigerant circulation system stops circulating, the second valve group has a state where the heat dissipation heat exchanger 13, the first pipeline 116 of the heat storage device 12 is conducted with the first heat exchanger 9, and the first pipeline 113 of the cold storage device 10 is cut off from the first heat exchanger 9; the third valve group has a state where the second pipeline 111 of the cold storage device 10 and the second pipeline 114 of the heat storage device 12 are cut off from the second heat exchanger 4.

[0157] The state of the second valve group connects heat dissipation heat exchanger 13 to the energy storage circulation system, first pipeline 116 of thermal storage device 12 to the energy storage circulation system, and first pipeline 113 of cold storage device 10 to the energy storage circulation system. The state of the third valve group disconnects second pipeline 114 of thermal storage device 12 and second pipeline 111 of cold storage device 10 from the energy storage circulation system. Therefore, through the circulation of first pump body 32, heat from thermal storage device 12 is released to heat dissipation heat exchanger 13, thereby realizing the heat storage and heating function of thermal storage device 12 providing heat to heat dissipation heat exchanger 13.

[0158] like Figure 11 The diagram shows a heat storage and heat supply cycle, with arrowed lines representing circulation loops. Compressor 6 is shut down, and the refrigerant does not circulate. The circulating water passes through the first pump body 32, the third three-way valve 54, and the fourth three-way valve 55, and is divided into two routes to enter the heat dissipation heat exchanger 13 and the first pipeline 116 in the heat storage device 12 for heat exchange. After the heat exchange is completed, the circulating water passes through the sixth three-way valve 58 and the fifth three-way valve 57 to enter the first heat exchanger 9 to begin the next heat exchange cycle. The circulating water delivers the heat in the heat storage device 12 to the heat dissipation heat exchanger 13 to complete the heat supply. This allows the heat storage device 12 to supply heat to the heat dissipation heat exchanger 13, and the heat dissipation heat exchanger 13 to generate heat.

[0159] Domestic water flows through the first pipe 116 in the heat storage device 12 to produce hot water.

[0160] like Figure 12 As shown, when the refrigerant circulation system stops circulating, the second valve group has a state in which the heat dissipation heat exchanger 13, the first pipeline 113 of the cold storage device 10 and the first heat exchanger 9 are connected, and the first pipeline 116 of the heat storage device 12 and the first heat exchanger 9 are cut off; the third valve group has a state in which the second pipeline 114 of the heat storage device 12 and the second pipeline 111 of the cold storage device 10 and the second heat exchanger 4 are cut off.

[0161] The second valve group is in a state where heat dissipation heat exchanger 13 is connected to the energy storage circulation system, first pipeline 116 of thermal storage device 12 is disconnected from the energy storage circulation system, and first pipeline 113 of cold storage device 10 is connected to the energy storage circulation system. The third valve group is in a state where second pipeline 114 of thermal storage device 12 and second pipeline 111 of cold storage device 10 are disconnected from the energy storage circulation system. Thus, the circulation of first pump 32 enables the cold storage device 10 to release cold energy to heat dissipation heat exchanger 13, thereby achieving the cold storage and cooling function of cold storage device 10 providing cold to heat dissipation heat exchanger 13.

[0162] like Figure 12The diagram shows a cold storage and cooling cycle, with arrowed lines representing circulation loops. Compressor 6 is shut down, and the refrigerant does not circulate. The circulating water is split into two routes through the first pump body 32 and the third three-way valve 54. One route passes through the fourth three-way valve 55 to enter the heat dissipation heat exchanger 13 for heat exchange, while the other route passes through the first pipeline 113 within the cold storage device 10 for cooling. After heat exchange with the heat dissipation heat exchanger 13, the circulating water passes through the sixth three-way valve 58 and then the fifth three-way valve 57, mixing with the circulating water cooled by the first pipeline 113 before entering the first heat exchanger 9 to begin the next cycle. The circulating water delivers the cold energy within the cold storage device 10 to the heat dissipation heat exchanger 13 to complete the cooling process. This ensures that the cold storage device 10 provides cooling to the heat dissipation heat exchanger 13, while the heat dissipation heat exchanger 13 also provides cooling.

[0163] Domestic water flows through the cold exchange pipe 112 in the cold storage device 10 to produce cold water.

[0164] like Figure 13 As shown, when the four-way valve is in the cooling state, the first valve group has a state in which the refrigerant heat exchanger 1 is connected to the refrigerant pipeline, and the second heat exchanger 4 is cut off from the refrigerant pipeline; the second valve group has a state in which the heat dissipation heat exchanger 13, the first pipeline 116 of the heat storage device 12 and the first heat exchanger 9 are connected, and the first pipeline 113 of the cold storage device 10 and the first heat exchanger 9 are cut off; the third valve group has a state in which the second pipeline 114 of the heat storage device 12, the second pipeline 111 of the cold storage device 10 and the second heat exchanger 4 are cut off.

[0165] The state of the first valve group connects refrigerant heat exchanger 1 to the refrigerant circulation system, while second heat exchanger 4 disconnects from the refrigerant circulation system. The state of the second valve group connects heat dissipation heat exchanger 13 to the energy storage circulation system, first pipeline 116 of heat storage device 12 connects to the energy storage circulation system, and first pipeline 113 of cold storage device 10 disconnects from the energy storage circulation system. The state of the third valve group disconnects second pipeline 114 of heat storage device 12 and second pipeline 111 of cold storage device 10 from the energy storage circulation system. Thus, through the circulation of first pump body 32, heat from heat storage device 12 can be released to heat dissipation heat exchanger 13 and first heat exchanger 9, thereby achieving the function of heating first heat exchanger 9 while improving the defrosting effect of refrigerant heat exchanger 1.

[0166] like Figure 13As shown in the figure, it is a heat storage heating cycle diagram, and the connecting lines with arrows are the circulation loops. The four-way valve 8 is switched to the refrigeration state. The first heat exchanger 9 is an evaporator. The refrigerant flows out of the compressor 6 and enters the four-way valve 8, then enters the refrigerant heat exchanger 1 (for defrosting the refrigerant heat exchanger 1) through the first three-way valve 51, exchanges heat with the external environment, enters the throttling element 7 through the second three-way valve 52 for throttling, then enters the first heat exchanger 9 to absorb the heat of the circulating water, and then flows back to the compressor 6 through the four-way valve 8. The circulating water is divided into two paths through the first pump body 32, the third three-way valve 54 and the fourth three-way valve 55 and enters the heat dissipation heat exchanger 13 and the first pipeline 116 in the heat storage device 12 respectively for heat exchange. After the heat exchange is completed, the circulating water enters the first heat exchanger 9 through the sixth three-way valve 58 and the fifth three-way valve 57 to start the next heat exchange cycle. The circulating water sends the heat in the heat storage device 12 to the heat dissipation heat exchanger 13 to complete heating, and at the same time heats the refrigerant in the first heat exchanger 9 to provide the heat required for defrosting the refrigerant heat exchanger 1. It realizes that the heat storage device 12 provides heat for the heat dissipation heat exchanger 13 and improves the defrosting effect of the refrigerant heat exchanger 1.

[0167] The domestic water flows through the first pipeline 116 in the phase change heat storage device 12 to realize instant hot water supply.

[0168] Therefore, the energy storage device of the energy storage air conditioning system includes a heat storage device and a cold storage device. The heat storage device and the cold storage device can store the heat and cold generated by the air conditioner to improve the energy storage effect of the air conditioner; the second heat exchanger and the refrigerant heat exchanger are connected to the pipeline through the first valve group. The first pipelines of the heat storage device and the cold storage device, and the heat dissipation heat exchanger are connected in parallel and connected to the first heat exchanger through the second valve group.
