[0047] Beneficial effects:

[0048] 1. To ensure that global warming is limited to within 1.5°C, countries around the world should restrict or even replace HFC refrigerants, the main culprits of greenhouse gases. Lithium bromide is not a greenhouse gas; therefore, lithium bromide absorption chillers should be vigorously developed to fulfill our due responsibility and make our due contribution to curbing global climate change.

[0049] 2. Electric lithium bromide absorption chiller units can generate grid-side energy storage projects, with a one-time investment and energy storage efficiency and economic benefits that are far superior to water storage or compressed air energy storage power generation projects.

[0050] 3. Since air conditioning is a major consumer of electricity in summer, and climate change leads to frequent power shortages for air conditioning every year; and heating is the largest consumer of electricity in winter, using lithium bromide absorption chillers and their energy storage cooling and heating systems can not only solve the aforementioned power shortages but also alleviate the investment pressure of grid expansion.

Utilizing lithium bromide without HFCs refrigerants, it revolutionizes refrigeration compression cycle air conditioning systems to address global warming.

[0074] Lithium bromide absorption chiller units and energy storage cooling and heating systems, including electromagnetic induction heating lithium bromide absorption chiller units, as shown in the attached document. Figure 1 As shown, the present invention provides an embodiment of an electromagnetic induction heating lithium bromide absorption air conditioning unit.

The system comprises a refrigerant water spray device 23 for a high-temperature generator, an evaporator 24, refrigerant water for the evaporator 27, a refrigerant water spray pump for the evaporator 28, a refrigerant water spray device 29 for the evaporator, a concentrated solution output pipe 30, a dilute solution input pipe 31, a high-temperature heat exchanger 32, a primary side of the high-temperature heat exchanger 33, a secondary side of the high-temperature heat exchanger 34, a refrigeration / heating switching valve 35, a refrigeration / heating switching valve 36, a low-temperature heat exchanger 37, a primary side of the low-temperature heat exchanger 38, a secondary side of the low-temperature heat exchanger 39, an absorbent output pump 40, a dilute absorbent solution 41, a concentrated solution spray device 42, a refrigeration / heating switching valve 43, and high-temperature insulation material 48.

[0075] The main structure of the aforementioned lithium bromide absorption air conditioning unit is similar to that of existing technologies. Therefore, the connection relationships between the various components will not be described in detail. This application mainly improves the heat source of the high-temperature generator. The electromagnetic induction heating lithium bromide absorption air conditioning unit is an electric lithium bromide unit. The generator adopts an electric high-temperature generator, which replaces the existing steam, hot water, and direct-fired heat sources with electric heating. By using lithium bromide without HFCs refrigerants, it revolutionizes the refrigeration compression cycle air conditioning system to address the problem of global warming. The electric lithium bromide absorption air conditioning unit can also generate grid user-side energy storage projects, which can solve a series of development problems of grid user-side energy storage.

[0076] Figure 1 In the electric high-temperature generator 10, a concentrated lithium bromide solution 11 is disposed at the lower part of the cylinder 2, while a domestic hot water heat exchanger 12, a heating heat exchanger 13, and a refrigerant steam output pipe 14 are disposed at the upper part of the high-temperature generator 10. High-temperature insulation material 48 is disposed on the exterior of the electric high-temperature generator cylinder 2, and one or more sets of electromagnetic induction heating coils 9 are wound around the outside of the high-temperature insulation material 48. An electromagnetic induction high-frequency generator 3 outputs high-frequency current to the electromagnetic induction heating coils 9 through electromagnetic induction high-frequency current output connecting lines 7 and 8, generating a high-frequency alternating magnetic field around the electromagnetic induction heating coils 9 and generating magnetic lines of force longitudinally in the electromagnetic induction heating coils 9. These magnetic lines of force penetrate the electric high-temperature generator cylinder 2. Since the electric high-temperature generator cylinder 2 is made of iron, a strongly magnetic material, an electric field is generated under the influence of the magnetic field, inducing a current within the electric high-temperature generator cylinder 2 and forming a large number of eddy currents. Because the cylinder 2 of the electric high-temperature generator is made of ferromagnetic material with low resistivity, strong eddy currents are generated, producing high-temperature heat. This heats the concentrated lithium bromide solution 11 stored inside the cylinder 2, causing a large amount of water in the concentrated lithium bromide solution 11 to evaporate, further concentrating the solution. The high-temperature concentrated lithium bromide solution 11 is then transported through the high-temperature heat exchanger 32, from the primary side 33 via the refrigeration / heating switching valve 35, to the concentrated solution spraying device 42, where it is sprayed onto the absorption heat exchanger 22. Another path passes through the low-temperature heat exchanger 37 and connects to the low-temperature generator dilute solution 17 via the primary side 38 of the low-temperature heat exchanger.

[0077] The refrigerant vapor output pipe 14 connects to the refrigerant vapor spraying device 16 via the refrigeration / heating conversion valve 43 and the low-temperature generator 15, spraying refrigerant vapor onto the condenser 18. After being cooled by the condenser 18, it forms refrigerant water 21, which is then output to the low-temperature generator refrigerant water spraying device 23. The low-temperature generator refrigerant water 21 is then sprayed onto the evaporator 24 to cool the air conditioning refrigerant water inside the evaporator 24. The air conditioning chilled water is then output through the chilled water inlet 25 and the chilled water outlet 26. Because the evaporator refrigerant water spraying pump 28 continuously circulates and outputs low-temperature chilled water to the evaporator refrigerant water spraying device 29, it sprays refrigerant water 27 onto the evaporator, cooling the air conditioning refrigerant water in the fan coil unit, thus cooling the air-conditioned room and achieving the purpose of refrigeration and air conditioning.

[0078] The concentrated solution spraying device 42 sprays a high-temperature concentrated lithium bromide solution 11 onto the absorption heat exchanger 22 and absorbs a large amount of water vapor from the evaporator, diluting the high-temperature concentrated lithium bromide solution 11. The solution then absorbs heat through the absorption heat exchanger 22, which is carried away by the condenser. The resulting dilute absorbent solution 41 is split into two outputs by the absorbent output pump 40. One output provides the required dilute solution 17 to the low-temperature generator 15 via the secondary side 39 of the low-temperature heat exchanger 37. The other output delivers the diluted solution 41 to the concentrated lithium bromide solution 11 in the electric high-temperature generator cylinder 2 via the high-temperature heat exchanger 32 and its secondary side 34 through the refrigeration / heating switching valve 36. This process repeats the heating process of heating the dilute solution 41 in the electric high-temperature generator cylinder 2 to form the concentrated lithium bromide solution 11.

[0079] During the process of heating the dilute solution 41 in the cylinder 2 of the electric high-temperature generator, a large amount of high-temperature water vapor heats the heating water in the heating heat exchanger 13 and provides heating hot water to the fan coil unit through the heating input interface 44 and the heating output interface 45 to heat the air-conditioned room and realize winter heating operation.

[0080] During the process of heating the dilute solution 41 in the cylinder 2 of the electric high-temperature generator, a large amount of high-temperature water vapor heats the domestic hot water heat exchanger 12 and provides domestic hot water through the domestic hot water output interface 46 and the domestic hot water input interface 47.

The quartz glass tube 50, heated to 1100°C, can be rapidly immersed in cold water without damage or malfunction. The carbon fiber heating wire 51 generates infrared heat with very little visible light, achieving an electrothermal conversion efficiency of over 95%, which is 30% more energy-efficient than heaters using nickel-chromium, tungsten-molybdenum, or other materials as heating elements.

[0084] Appendix Figure 4 This invention relates to an embodiment of an energy storage lithium bromide absorption chiller unit. (See attached diagram.) Figure 4 In this system, a thermal storage and heating heat exchanger 54 is installed inside the concentrated lithium bromide solution 11 of the electric high-temperature generator cylinder 2. The thermal storage and heating heat exchanger is connected to an external thermal storage device through the thermal storage and heating heat exchanger input interface 55 and the thermal storage and heating heat exchanger output interface 56. The system utilizes the cheap off-peak electricity from the power grid to store heat and realizes an energy storage lithium bromide absorption air conditioning unit. This not only provides low air conditioning operating costs but also serves as an energy storage device on the user side of the power grid.

[0085] Appendix Figure 5 This invention provides an embodiment of an externally mounted lower heat exchange coil heat storage and exchange device. (See attached image.) Figure 5 The lower heat exchange coil heat exchange device consists of a heat storage and heat exchange tank 57, a packing manhole 58, a heat storage medium heat exchange cylinder 59, a heat storage medium addition port 60, a heat storage medium 61, an external lower heat exchange coil 64, a heat exchange medium inlet pipe 65, and a heat exchange medium outlet pipe 66.

[0086] The thermal storage tank 57 contains a thermal storage medium 61, the material of which should be determined based on whether the thermal storage medium 61 is corrosive and the thermal storage temperature. Ferritic stainless steel should not be used to manufacture electromagnetic induction heating tanks for temperatures exceeding 600℃, as ferritic stainless steel will lose magnetism above 600℃, affecting electromagnetic induction efficiency. Martensitic or austenitic stainless steel should be used instead. The packing manhole 58 serves as a filling or inspection port for the thermal storage material, with the thermal storage medium filling port 60 located above the packing manhole 58. The thermal storage medium 61 is added by opening the discharge port 60.

[0087] Appendix Figure 5Suitable for a variety of heat storage media 61, such as water, oil, molten salt, liquid metal or rock sand. The appropriate material for heat storage media 61 can be selected based on the purpose of heat storage and the required temperature.

[0088] Appendix Figure 5 The heat exchange coil 64 is wound around the outside of the heat exchange cylinder 59 of the heat storage medium. The heat exchange coil 64 is in close contact with the surface of the heat exchange cylinder 59 of the heat storage medium, and the heat is transferred from the surface of the heat exchange cylinder 59 to the surface of the heat exchange coil 64. The heat is then transferred to the heating circulation medium circulating inside the heat exchange coil 64. The heat is then transferred through the heat exchange circulation input pipe 65 and the heat exchange circulation output pipe 66, and through the heat exchange input interface 67 and the heat exchange output interface 68 to the interface of the heating system that needs heating. The heat of the heat storage medium 61 is circulated out, realizing the combined operation of energy storage, heat exchange and heating.

[0089] Appendix Figure 5 The observation mirror 6 is configured to facilitate observation of the phase change process of the heat storage medium 61. The heat storage tank support 69 should ensure the load-bearing capacity of the heat storage tank 57 and ensure safe operation.

[0090] It should be noted that the appendix Figure 5 Externally mounted heat exchange coil thermal storage heat exchange devices can be used as independent energy storage and heating equipment in heating systems, or they can be used in conjunction with auxiliary equipment. Figure 4 The thermal storage and heating heat exchanger 54 is connected to the heat exchange input interface 67 and the heat exchange output interface 68 via the thermal storage and heating heat exchanger input interface 55 and the thermal storage and heating heat exchanger output interface 56. The circulating heat transfer medium will be attached Figure 5 The stored heat is supplied to the heat storage and heating heat exchanger 54.

[0091] Appendix Figure 6 This invention discloses an embodiment of a heat storage and heat exchange device with a built-in upper heat exchange coil. (See attached image.) Figure 6 The heat storage and heat exchange device with built-in upper heat exchange coil is composed of a heat storage and heat exchange tank 57, a packing manhole 58, a heat storage medium addition port 60, a heat storage medium 61, a tank atmospheric pressure breathing port 63, a heat exchange medium inlet pipe 65, a heat exchange medium outlet pipe 66, and a built-in upper heat exchange coil 70.

[0092] Appendix Figure 6 The heat exchange coil 70 is immersed in the heat storage medium 61 or suspended above the heat storage medium 61. The heat exchange medium inlet pipe 65 and the heat exchange medium outlet pipe 66 are fixedly arranged on the packing manhole 58 or on the heat storage and heat exchange tank 57.

[0093] Appendix Figure 6 It is attached Figure 5 Based on this, the built-in upper heat exchange coil 70 is fixedly installed on top of the packing manhole 58. This configuration brings many benefits and conveniences to practical applications. Other functions and accessories are as follows. Figure 5 They are basically the same.

[0094] The tank breather port 63 is configured to improve the safety of the heat storage tank 57. When the heat storage tank 57 expands, the tank breather port 63 discharges gas and pressure to the outside. When the heat storage tank 57 forms a negative pressure state, the tank breather port 63 draws in air from the outside, ensuring that the heat storage tank 57 always operates under a stable and reliable atmospheric pressure. To ensure tank cleanliness, the tank breather port 63 can be equipped with a conventional breather, using an air filter inside the breather to filter impurities in the air.

[0095] Appendix Figure 7 This invention provides an embodiment of a built-in lower heat exchange coil and a heat storage medium discharge plug. (See attached image.) Figure 7 It consists of a heat storage and heat exchange tank body 57, a packing manhole 58, a heat storage medium addition port 60, a heat storage medium 61, a tank body atmospheric pressure breathing port 63, a heat exchange medium inlet pipe 65, a heat exchange medium outlet pipe 66, an internal lower heat exchange coil 71, a breathing valve 72, and a heat storage medium discharge plug 73.

[0096] Appendix Figure 7 The heat exchange coil 71 is immersed in the heat storage medium 61, and the heat exchange medium inlet pipe 65 and heat exchange medium outlet pipe 66 are arranged on the heat storage medium heat exchange cylinder 59 or the heat storage medium discharge block plate 73.

[0097] Breathing valve 72 is positioned above atmospheric pressure breathing port 63 on the tank body and is connected to the heat storage tank 57 as an atmospheric pressure breathing device for the heat storage tank 57.

[0098] The breathing valve 72 can also be a conventional breathing apparatus, because conventional breathing apparatuses do not have a check valve and are only equipped with an air filter to prevent air impurities from entering the tank. Since this application is used for high-temperature thermal storage, the air filter in the breathing apparatus should be a high-temperature resistant metal air filter.

[0099] Appendix Figure 8 This invention relates to an embodiment of an externally mounted upper heat exchange coil heat storage and exchange device. (See attached image.) Figure 8 The external upper heat exchange coil heat exchange device consists of a heat storage and heat exchange tank 57, a packing manhole 58, a heat storage medium addition port 60, a heat storage medium 61, a tank atmospheric pressure breathing interface 63, a heat exchange medium inlet pipe 65, a heat exchange medium outlet pipe 66, an external upper heat exchange coil 85, and a breathing valve 72.

[0100] Appendix Figure 8 In this configuration, at least one or more externally mounted heat exchange coils 85 or at least one or more coils of a shell-and-tube sheet heat exchanger are disposed outside the heat storage tank 57, serving as a heat exchange output device for the heat storage medium 61. Other components are related to the appendix. Figure 5 The same applies, so I won't go into details.

[0101] A heat exchanger for the heat storage medium and heating water is constructed using one or more turns of heat exchange coils (85) or one or more turns of tube-plate heat exchangers, transferring the stored heat energy to the heating circulating water for heating. This embodiment uses one or more turns of heat exchange tubes or tube-plate heat exchangers to facilitate adjustment of the heat exchange capacity, thereby saving the circulating water's power energy.

[0102] Heat exchange coils exchange heat between circulating water inside the tubes and the heat storage medium inside the tank via the steel plates of the heat storage tank. Tube sheet heat exchangers circulate heating water through water channels between the tube sheet (which is fitted over the outside of the heat storage tank) and the tank body, transferring the heat stored in the heat storage medium to the heating water to achieve the purpose of heating the water and completing the heat exchange.

[0103] Appendix Figure 9 This invention provides an embodiment of an electromagnetic induction heating type thermal storage and heat exchange system. (See attached document.) Figure 9 The system comprises a heat storage and heat exchange tank 57, a packing manhole 58, a heat storage medium heat exchange cylinder 59, a heat storage medium addition port 60, a heat storage medium 61, a tank atmospheric pressure breathing port 63, an external lower heat exchange coil 64, a heat exchange medium inlet pipe 65, a heat exchange medium outlet pipe 66, a breather valve 72, insulation material 74, at least one set of electromagnetic induction heating coils 75, an electromagnetic induction high-frequency current output connection line 76, and an electromagnetic induction high-frequency current output connection line 77, forming an electromagnetic induction heating type heat storage and heat exchange system.

[0104] The insulation material 74 is uniformly wrapped around the outer surface of the heat storage and heat exchange tank 57, as well as the outer surface of the external heat exchange coil 64, the heat exchange medium inlet pipe 65, and the heat exchange medium outlet pipe 66.

[0105] Appendix Figure 9 The electromagnetic induction heating coil 75 is wound around the outside of the insulation material 74 as a heating device for the heat storage and heat exchange tank 57, so as to heat the heat storage medium 61 through the heat storage and heat exchange tank 57.

[0106] Appendix Figure 9 In addition to the appendix Figure 4 In addition to being connected to form an energy storage type lithium bromide refrigeration and air conditioning system, the heat exchanger 54 can also be used independently as a winter heating device, serving as a heat source for a household or commercial winter energy storage heating system.

[0107] Appendix Figure 10 This invention discloses an embodiment of an electrically heated tubular thermal storage and heat exchange system. (See attached document.) Figure 10The electric heating tube type heat storage and heat exchange system consists of a heat storage and heat exchange tank 57, a packing manhole 58, a heat storage medium heat exchange cylinder 59, a heat storage medium addition port 60, a heat storage medium 61, a tank atmospheric pressure breathing interface 63, an external lower heat exchange coil 64, a heat exchange medium inlet pipe 65, a heat exchange medium outlet pipe 66, a breather valve 72, insulation material 74, at least one carbon fiber heating tube 80, a quartz glass tube 81, and a carbon fiber heating wire 82.

[0108] Appendix Figure 10 The carbon fiber heating tube 80 is disposed in the heat storage and heat exchange tank 57 and immersed in the heat storage medium 61 as a heating device for the heat storage medium 61.

[0109] Appendix Figure 10 In addition to the appendix Figure 4 In addition to being connected to form an energy storage type lithium bromide refrigeration and air conditioning system, the heat exchanger 54 can also be used independently as a winter heating device, serving as a heat source for a household or commercial winter energy storage heating system.

[0110] Appendix Figure 11 This invention provides an embodiment of a configuration of a breathing valve and a nitrogen-based thermal storage and exchange system. (See attached diagram.) Figure 11 The heat storage and heat exchange system consists of a heat storage and heat exchange tank 57, a packing manhole 58, a heat storage medium heat exchange cylinder 59, a heat storage medium inlet 60, a heat storage medium 61, an observation mirror 62, a tank atmospheric pressure breathing port 63, an external lower heat exchange coil 64, a heat exchange medium inlet pipe 65, a heat exchange medium outlet pipe 66, a breathing valve 72, a nitrogen tank 86, and a nitrogen tank 87.

[0111] Appendix Figure 11 In this system, the breather valve 72 is connected to the heat storage and heat exchange tank 57 via the atmospheric pressure breather port 63 and is in communication with the heat storage medium 61. The exhalation end of the breather valve 72 is connected to the air, and the inhalation end is connected to the nitrogen tank 86 and is in communication with the nitrogen 87 inside the nitrogen tank 86. The observation mirror 62 is mounted on the heat storage tank 57 or the packing manhole 58 and allows observation of the position of the heat storage medium 61.

[0112] Appendix Figure 12 This invention discloses an embodiment of a silicone respirator-type thermal storage and heat exchange system. (See attached document.) Figure 12 The thermal storage and heat exchange system consists of a thermal storage and heat exchange tank 57, a packing manhole 58, a thermal storage medium heat exchange cylinder 59, a thermal storage medium addition port 60, a thermal storage medium 61, an observation mirror 62, a tank atmospheric pressure breathing interface 63, an external lower heat exchange coil 64, a heat exchange medium inlet pipe 65, a heat exchange medium outlet pipe 66, a breather valve 72, a silicone breather 97, a silicone viewing glass cover 98, an oil-sealed glass cup 99, a breather hole 100, and silicone 101.

The silicone breather 97 is equipped with silicone 101. The heat storage medium 61 is connected to the atmosphere through the silicone 101, the oil-sealed glass cup 99, and the breathing hole 100, serving as the atmospheric pressure breathing channel between the heat storage and heat exchange tank 57 and the atmosphere.

[0114] Appendix Figure 12 The glass cup 99 is filled with high-temperature oil, such as heat-conducting oil. The purpose is to use the oil as a medium to isolate the silicone 101 from the atmosphere, preventing the silicone respirator 97 from being in contact with the air for a long time, so as to avoid moisture and impurities in the air from contaminating the silicone 101.

[0115] Appendix Figure 13 This invention relates to an embodiment of an energy storage lithium bromide absorption chiller unit equipped with an electromagnetic induction heating thermal storage and heat exchange system. (See attached document.)

The other end of the external lower heat exchange coil 64 is connected via the heat exchange output interface 68, through the energy storage cooling / heating conversion valve 92, and then through the energy storage heating heat exchanger input interface 55 to the other end of the energy storage heating heat exchanger 54. The other end is connected via the energy storage cooling / heating conversion valve 95 to the energy storage cooling / heating conversion valve 94 and the heating input interface 44, forming an independent heating system for winter. This eliminates the need for a lithium bromide system for heating, thus extending the lifespan of the lithium bromide system.

[0117] One end of the electromagnetic induction heating coil 75 is connected to the electromagnetic induction high-frequency generator 3 via the electromagnetic induction coil lead 76, the electromagnetic induction heating controller power connection terminal 78, the electromagnetic induction high-frequency current output connection line 8, and the electromagnetic induction high-frequency current output interface 6.

[0118] The heat storage tank 57 converts wind and solar power generation, as well as off-peak electricity from the grid, into heat for the heat storage medium 61, which is then stored. During peak electricity periods, the stored energy is supplied to the high-temperature generator 10 via the heat storage tank 57 and the energy storage heating heat exchanger 54, forming a summer cooling and air conditioning system for the energy storage lithium bromide absorption chiller. In winter, the heat storage tank 57 forms an energy storage heating system. The cooling / heating switching valves 35, 36, and 43 can also be used to form a conventional heating system and a domestic hot water supply system. Since this is a conventional lithium bromide chiller heating system, it will not be described further.

[0119] Appendix Figure 14 This invention relates to an embodiment of a lithium bromide absorption chiller unit equipped with a carbon fiber electric heating tube thermal storage and heat exchange system. (See attached document.)
