Description

Technical Field

[0001] The present invention relates to the fields of renewable energy, heat storage, electricity storage, and improvement of life in high-altitude areas, and specifically to a high-quality life system for residents in high-altitude areas based on the synergy of electricity, heat, and oxygen. Background Art

[0002] Due to the thin air in high altitude areas, large temperature differences between day and night, cold weather, and low glacier meltwater temperature below 10 degrees all year round, life is very difficult. Local residents have poor basic infrastructure such as power supply, heating and oxygen supply, and it is difficult to effectively guarantee important energy and materials such as electricity, heat and oxygen to maintain survival.

[0003] While solar energy resources are abundant at high altitudes, they also have unique lighting characteristics due to differences in topography. Furthermore, solar energy resources are poorly matched to load demand, regardless of season or sunrise or sunset. Cold spells are relatively long, with high heat load demand and reduced solar power generation. Conversely, warm spells are relatively low, with relatively low heat load demand and increased solar power generation.

[0004] Based on the household needs of border residents, relatively low energy consumption, and cost considerations, solar energy resources are used to solve practical problems such as year-round power, heating, and oxygen supply. This approach also addresses the mismatch between load demand and solar time availability, the rational use of secondary energy for equipment operation, energy supply security, and improved energy efficiency, providing a comfortable life on the plateau. At the same time, consideration is given to local economic development, affordability, practicality, user-friendliness, and reliability. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a high-quality life system for residents in high-altitude areas based on the synergy of electricity, heat and oxygen. It uses photovoltaic power generation as energy and chemical electricity storage to meet the power supply needs throughout the year; photovoltaic power generation is used for heating, sensible heat and latent heat storage are carried out simultaneously, and biomass boilers are coordinated to supplement heat to solve short-term and cross-seasonal heating needs; based on the requirements of safe and reliable equipment operation, compressed air and nitrogen oxide membrane separation technology are used to fill the sealed insulation cabin with nitrogen at 1 atmosphere pressure, which not only solves the fire prevention, heat dissipation and derating of the equipment, but also solves the problem of air separation oxygen production to meet the oxygen supply problem of life, and uses a photovoltaic storage integrated machine to solve the year-round power supply problem.

[0006] The present invention uses chemical energy storage in an integrated photovoltaic and storage unit and rationally allocates capacity to solve the problem of power supply throughout the year; uses the sensible hot water body of the photovoltaic water electrode boiler to store heat for a relatively short period of time on a daily basis, combines phase change material heat storage with cross-seasonal heat storage in conjunction with the biomass boiler, and uses multiple heat complementarity to solve the problem of domestic heating throughout the year; the air compressor compresses air through nitrogen and oxygen separation technology to provide positive pressure nitrogen protection for the sealed and insulated cabin, solving the problems of equipment derating at high altitudes, heat dissipation, safety, etc. At the same time, the nitrogen and oxygen separation technology solves the air separation oxygen supply problem to solve the local domestic oxygen supply problem.

[0007] The principle of the present invention is:

[0008] (1) Use a sealed thermal insulation cabin to place the photovoltaic and energy storage device, storage battery, heat exchanger and other devices in the sealed thermal insulation cabin, and place the water electrode heating device and phase change material device in the basement or insulated cellar. Use an air compressor to compress air into the sealed thermal insulation cabin, and use semi-permeable membrane technology to pressurize 1 atmosphere of nitrogen, while separating the oxygen from the air. This achieves nitrogen protection for the equipment in the sealed thermal insulation cabin and solves the following problems:

[0009] 1. The sealed insulation chamber is filled with nitrogen at 1 atmosphere pressure to solve the problem of equipment derating;

[0010] 2. The positive pressure in the sealed and insulated cabin prevents dust from entering from outside;

[0011] 3. Nitrogen protection in the sealed and insulated cabin actively prevents fire and equipment heat exchange problems;

[0012] 4. Semi-permeable membrane technology for physical air separation oxygen production to meet daily needs;

[0013] 5. The cold water heat exchanger acts as a cooling source to exchange heat with the nitrogen in the sealed insulation cabin. On the one hand, it regulates the temperature of the sealed insulation cabin to ensure the equipment operates normally at the optimal temperature. On the other hand, the cold water exchanges heat in the sealed insulation cabin to increase the temperature of domestic water. At the same time, part of the heat-exchanged water is further heated by the water electrode boiler to improve the quality of domestic heat.

[0014] (2) Phase change materials, used as a cross-seasonal heat storage material, are placed in the center of the photovoltaic water electrode boiler. They are isolated from the water by insulation, reducing the temperature difference between the inside and outside of the insulation material, which is beneficial for heat preservation. The phase change material exchanges heat with the photovoltaic water electrode boiler through the phase change heat exchanger.

[0015] Phase change thermal storage technology offers the advantage of high heat storage density in low- to medium-temperature regions. The supercooling properties of some phase change materials allow them to maintain a supercooled state below their melting point, where latent heat is not released. This supercooling property enables long-term, cross-seasonal solar thermal storage, providing technical support for achieving "summer heat and winter use" in buildings in cold regions.

[0016] (3) Based on the principle of a water electrode boiler, the heating power can be varied by changing the distance between the fixed and movable water electrodes to alter the water resistance. Because the photovoltaic water electrode sensible and latent heat storage boiler can start linearly with zero power, it can be controlled to track the photovoltaic maximum power output. In conjunction with the integrated photovoltaic and storage system, it can achieve lossless absorption of the maximum power during the photovoltaic power generation cycle.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other. The present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1 and Figure 2 As shown, the high-quality life system for residents in high-altitude areas based on the synergy of electricity, heat and oxygen of the present invention includes a main controller 1, a sealed insulation cabin 2, a photovoltaic module 3, a photovoltaic storage integrated machine 4, a photovoltaic water electrode sensible heat and latent heat storage boiler 5, and an air supply unit 6.

[0043] The sealed, insulated chamber 2 is thermally insulated and airtight, including a second pressure-reducing valve 26, integrally packaged with a pressure sensor and embedded within the chamber. One end of the valve communicates with the interior of the chamber and the other with the atmosphere outside, ensuring a constant relative positive pressure of nitrogen within the chamber. The integrated photovoltaic and energy storage system 4 includes an energy storage battery 7 and a sealed, insulated chamber heat exchanger 8, both located within the chamber. An air supply unit 6 is located outside the chamber. The chamber is mounted on the exterior wall of the building, providing insulation. The photovoltaic and water-based sensible and latent heat storage boiler 5 is located in a basement 9 or an insulated cellar. The photovoltaic modules 3 are mounted on the roof or around the residence. The module output 10 is connected via cables through the sealed, insulated chamber 2 to the integrated photovoltaic and energy storage system's DC input 11 and through the basement 9 to the photovoltaic and water-based sensible and latent heat storage boiler's low-frequency converter 12, providing energy from photovoltaic power generation.

[0044] like Figure 1 、 Figure 3 As shown, the air supply unit 6 includes an air compressor 13, a nitrogen-oxygen separation membrane module 14, and a floating-roof oxygen tank 15. The air compressor 13 is placed on the ground outside the sealed and insulated cabin 2. The air compressor inlet 16 is connected to the atmosphere, and the air compressor exhaust is embedded in the nitrogen-oxygen separation membrane module 14. Compressed air from the air compressor 13 is connected to the interior of the sealed and insulated cabin 2 via a nitrogen outlet 17. The compressed air from the air compressor 13 flows through the nitrogen-oxygen separation membrane module 14 and the nitrogen outlet 17 to provide a relatively positive pressure of approximately 1 atmosphere of nitrogen to the sealed and insulated cabin 2, addressing heat dissipation, active fire protection, dust control, and equipment derating within the sealed and insulated cabin 2.

[0045] The compressed gas is separated into oxygen through the nitrogen and oxygen separation membrane module 14 and compressed into the floating roof oxygen tank 15 connected thereto through the oxygen output port 18. The floating roof oxygen tank 15 provides oxygen for daily use through the oxygen supply pipeline 19 and the first pressure reducing valve 20.

[0046] The main controller 1 is embedded and installed on the inner wall of the user's house, and the main controller 1 has a built-in touch screen 21 and a communication interface 22 .

[0047] Communication interface 22 is connected to the integrated solar-energy storage unit controller 23, the photovoltaic-water sensible and latent heat storage boiler controller 24, the environmental monitor 25, and all sensors via communication cables. Main controller 1 reads data from all sensors, the environmental monitor 25, and the integrated solar-energy storage unit controller 23 and the photovoltaic-water sensible and latent heat storage boiler controller 24 via communication interface 22 and cables. Based on collected data analysis, mathematical model calculations, and control strategies, main controller 1 controls the integrated solar-energy storage unit 4 and the photovoltaic-water sensible and latent heat storage boiler 5 via communication interface 22 and cables to ensure optimal power and temperature supply.

[0048] Furthermore, the sealed and insulated chamber heat exchanger 8 includes a heat exchanger inlet pipe 27 and a heat exchanger outlet pipe 28. The sealed and insulated chamber heat exchanger 8 is positioned in the upper portion of the sealed and insulated chamber 2. The heat exchanger inlet pipe 27 passes through the sealed and insulated chamber 2 and connects to an external water source. The heat exchanger outlet pipe 28 communicates with the water inlet 29 of the photovoltaic water electrode sensible and latent heat storage boiler. Local water sources at high altitudes are often glacial meltwater, with temperatures below 10°C year-round. The sealed and insulated chamber heat exchanger 8 uses the low-temperature water flowing through the heat exchanger inlet pipe 27 to exchange heat with nitrogen within the sealed and insulated chamber 2. This not only lowers the temperature inside the sealed and insulated chamber 2, ensuring proper operation of the equipment, but also raises the temperature of the water entering the photovoltaic water electrode sensible and latent heat storage boiler 5 through the heat exchanger outlet pipe 28 and the photovoltaic water electrode sensible and latent heat storage boiler water inlet 29, preheating the water in the photovoltaic water electrode sensible and latent heat storage boiler 5 and reducing the power consumption of the photovoltaic water electrode sensible and latent heat storage boiler 5.

[0049] The photovoltaic and energy storage integrated machine 4 includes an energy storage battery 7. The DC input terminal 11 of the photovoltaic and energy storage integrated machine is connected to the positive and negative terminals of the photovoltaic module output terminal 10 through a cable. The electricity generated by the photovoltaic module 3 is converted by the photovoltaic and energy storage integrated machine 4, and then passes through the AC output terminal 30 of the photovoltaic and energy storage integrated machine and the cable 31 to supply power to the air compressor 13, the photovoltaic and energy storage integrated machine controller 23, the photovoltaic water electrode sensible heat and latent heat storage boiler controller 24, and the daily electricity. The minimum remaining power of the main controller 1 is Under the control of the allocation strategy based on the function and the principle of prioritizing heating with electricity storage as the auxiliary principle, the storage capacity of the energy storage battery 7 is optimized according to the local lighting conditions to ensure the power supply demand for life for a certain period of time.

[0050] like Figure 3As shown, the photovoltaic water electrode sensible and latent heat storage boiler 5 functions as water heating, insulation, and phase change heat storage. It is located in a basement 9 or insulated cellar. Based on the heating principle of the electrode hot water boiler, voltage and current are passed through water of a set conductivity, releasing a large amount of heat energy, directly converting electrical energy into thermal energy and generating steam. The heating power can be adjusted steplessly. Due to the direct heating of the water resistance, 100% of the electrical energy is converted into heat, achieving high efficiency and virtually no heat loss.

[0051] The photovoltaic water electrode sensible heat and latent heat storage boiler 5 includes a heating water electrode unit 48 , a phase change heat storage unit 39 , a heat preservation tank 34 and a water body 45 .

[0052] The insulation tank 34 is filled with water 45, and the heating water electrode unit 48 and the phase change heat storage unit 39 are placed in the water 45 in the insulation tank 34, each located in a different half of the insulation tank 34. The insulation tank 34 also includes the photovoltaic water electrode sensible heat and latent heat storage boiler inlet 29, the domestic heating outlet 46, and the domestic heating return water inlet 47.

[0053] The glacier meltwater exchanges heat through the heat exchanger outlet pipe 28 and enters the water body 45 of the photovoltaic water electrode sensible and latent heat storage boiler 5 through the photovoltaic water electrode sensible and latent heat storage boiler inlet 29. The water body 45 heated by the photovoltaic water electrode sensible and latent heat storage boiler 5 is then used to provide heat and domestic water through the domestic heating outlet 46 and domestic heating return water inlet 47.

[0054] Furthermore, the phase change heat storage unit 39 includes a phase change material sealed container 40, a phase change material 41, and a phase change heat exchanger 42. The phase change material sealed container 40 is filled with the phase change material 41, and the phase change heat exchanger 42 is placed in the phase change material 41. The phase change material sealed container 40 is made of an insulating material, which separates the water body of the photovoltaic water electrode sensible heat and latent heat storage boiler 5 from the phase change material 41. Because the heat preservation of an object is related to the thermal conductivity of the insulating material, the temperature difference between the inside and outside, etc., when the thermal conductivity of the insulating material is constant, the smaller the temperature difference between the inside and outside of the phase change material sealed container 40, the better the heat preservation effect. Therefore, the phase change material sealed container 40 is placed in the water body 45 of the photovoltaic water electrode sensible heat and latent heat storage boiler 5.

[0055] An upper temperature control valve 43 is installed at the upper end of the phase change heat exchanger 42 and is connected to the water body 45. A lower control valve 44 is installed at the lower end of the phase change heat exchanger 42 and is connected to the water body 45. Thus, the phase change heat exchanger 42 establishes a water circulation loop with the water body 45 through the upper temperature control valve 43 and the lower control valve 44, and the water body 45 exchanges temperature with the phase change material 41.

[0056] When the temperature of water 45 is higher than the melting point of phase change material 41, phase change material 41 absorbs heat from water 45 via upper temperature control valve 43, lower control valve 44, and phase change heat exchanger 42, storing the relatively high-temperature heat. When the temperature of water 45 is lower than the domestic heating temperature, phase change material 41 releases heat to water 45 under controlled conditions via upper temperature control valve 43, lower control valve 44, and phase change heat exchanger 42, raising the temperature of water 45. Because the phase change material 41 exchanges heat with water 45 through phase change heat exchanger 42, controlled temperature, and insulation from the insulating material, long-term heat preservation is achieved. The melting point of phase change material 41 is higher than the domestic heating temperature.

[0057] Furthermore, the heating water electrode unit 48 includes a movable water electrode 36 , a fixed water electrode 35 , and a transmission unit 32 .

[0058] The transmission unit 32 includes a drive motor 37, a drive screw 38, and a photovoltaic water electrode sensible and latent heat storage boiler controller 24. The movable water electrode 36 is connected to the drive screw 38 via a threaded connection. The rotation of the drive screw 38, driven by the drive motor 37, controls the horizontal movement of the movable water electrode 36, thereby changing the distance between the movable water electrode 36 and the fixed water electrode 35. Since the product of the volume and resistivity of the water between the movable water electrode 36 and the fixed water electrode 35 is called water resistance, the greater the relative distance between the movable water electrode 36 and the fixed water electrode 35, the greater the water resistance, and vice versa. The photovoltaic water electrode sensible and latent heat storage boiler controller 24 can determine the water resistance by detecting the relative distance between the movable water electrode 36 and the fixed water electrode 35. Based on data from the main controller 1 and the photovoltaic maximum power point tracking strategy, it controls and adjusts the relative distance between the movable water electrode 36 and the fixed water electrode 35 in real time, achieving photovoltaic maximum power point tracking and ensuring maximum photovoltaic power generation efficiency.

[0059] Thus, the movable water electrode 36 and the fixed water electrode 35 are connected to the low-frequency converter 12 of the photovoltaic water electrode sensible and latent heat storage boiler, directly absorbing the power from the photovoltaic module output 10 and enabling the photovoltaic module 3 to almost directly power the photovoltaic water electrode sensible and latent heat storage boiler 5. The photovoltaic water electrode sensible and latent heat storage boiler 5 operates similarly to a traditional AC water electrode boiler operating at a 50Hz power frequency with a switching time of 0.2 seconds. However, the conventional AC water electrode boiler's AC power frequency constant voltage output is replaced by a system that directly follows the photovoltaic power generation voltage. The photovoltaic water electrode sensible and latent heat storage boiler's low-frequency converter 12 uses a lower-frequency electronic or mechanical switch to switch the water electrode polarity, eliminating the photovoltaic DC-to-AC inverter, reducing costs and losses. This reduces the switching time of the photovoltaic water electrode sensible and latent heat storage boiler's low-frequency converter 12 while ensuring that the movable water electrode 36 and the fixed water electrode 35 are not polarized, thereby improving photovoltaic power generation efficiency.

[0060] The main controller 1 reads the numerical weather forecast in real time, monitors the photovoltaic power generation data, and communicates with the photovoltaic water electrode sensible heat and latent heat storage boiler controller 24 based on the optimal target function of heating and heat storage, electricity storage and heat storage control strategy, and controls the photovoltaic water electrode sensible heat and latent heat storage boiler 5 to change the distance between the movable water electrode 36 and the fixed water electrode 35, thereby changing the water resistance. With water flowing through the resistance Current The water resistance heating power is obtained by Based on the principle of photovoltaic maximum power point tracking, the water resistance heating power is adjusted Equal to the photovoltaic maximum power point Right now , thereby achieving the photovoltaic maximum power point of the photovoltaic water electrode sensible heat and latent heat storage boiler 5 Tracking, new energy is maximized.
