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 difference between day and night, cold weather, and low glacier meltwater temperature which is often below 10 degrees Celsius all year round, life is very difficult. Local residents have poor basic infrastructure such as basic electricity, 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] Due to the high altitude, solar energy resources are abundant, but due to the differences in topographic lighting conditions, it has unique lighting characteristics. At the same time, solar energy resources have a low matching degree with load demand regardless of season or sunrise and sunset. The cold period is relatively long and the heat load demand is large, and solar power generation during this period is reduced. Conversely, the heat load is relatively reduced during the warm period, and solar power generation during this period increases.

[0004] Based on the needs of border residents, relatively low energy consumption and cost considerations, solar energy resources are used to solve practical problems in life such as power supply, heating, and oxygen supply throughout the year, while solving the problem of mismatch between load demand and solar time, the rational use of secondary energy for equipment operation, energy supply security, and improving the efficient use of energy to provide a comfortable life on the plateau. At the same time, local economic development, affordability, practicality, operability, friendliness, and reliability are taken into consideration. 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. Photovoltaic power generation is used as the energy source, and chemical electricity storage is used 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 achieve the solution of 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 problem of power supply throughout the year.

[0006] The present invention uses chemical energy storage in an integrated photovoltaic and energy storage machine and reasonably configures 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-season heat storage in coordination with the biomass boiler, and uses multiple heat complementarity to solve the problem of heating for daily life; 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, heat dissipation, safety, etc. at high altitudes; at the same time, the nitrogen and oxygen separation technology is used to solve the problem of local oxygen supply for daily life through air separation oxygen supply.

[0007] The principle of the present invention is:

[0008] (I) Use a sealed thermal insulation cabin to place the integrated photovoltaic and energy storage device, storage battery, heat exchanger and other devices in the sealed thermal insulation cabin, and place the water electrode heating, phase change material and other devices in the basement or thermal 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 oxygen from the air. Achieve nitrogen protection for the equipment in the sealed thermal insulation cabin, and solve the following problems at the same time:

[0009] 1. One atmosphere of nitrogen pressure in the sealed insulation cabin solves the problem of equipment derating;

[0010] 2. The positive pressure in the sealed insulation cabin solves the problem of dust 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 physical air separation oxygen production to meet life needs;

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

[0014] (ii) Phase change materials are used as cross-season heat storage materials. They are placed in the middle of the photovoltaic water electrode boiler and isolated from the water body by the insulation material, which reduces the temperature difference between the inside and outside of the insulation material and is beneficial to heat preservation. The phase change material exchanges heat with the photovoltaic water electrode boiler through the phase change heat exchanger.

[0015] Among them, phase change heat storage technology has the advantage of high heat storage density in medium and low temperature areas. The supercooling characteristics of some phase change materials can keep the latent heat below the melting point in a supercooled state without releasing it. The supercooling characteristics of phase change materials can be used to achieve long-term and cross-seasonal solar heat storage, providing technical support for buildings in cold areas to achieve "summer heat and winter use".

[0016] (III) Based on the principle of water electrode boiler, the heating power can be changed by changing the distance between the fixed and mobile water electrodes to change the size of the water resistance. Since the photovoltaic water electrode sensible heat and latent heat storage boiler can start linear heating at 0 power, the photovoltaic maximum power tracking of the photovoltaic water electrode sensible heat and latent heat storage boiler can be achieved through control, and the maximum power lossless absorption during the photovoltaic power generation cycle can be achieved in conjunction with the photovoltaic storage integrated machine.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with 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 can be combined with each other as long as they do not conflict with each other. The present invention is further described below in conjunction with 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 a gas supply unit 6.

[0043] The sealed insulation cabin 2 has the characteristics of insulation and sealing, including a second pressure reducing valve 26, which is integrated with the pressure sensor and embedded on the top of the sealed insulation cabin 2, one end of which is connected to the inside of the sealed insulation cabin 2, and the other end is connected to the atmosphere outside the sealed insulation cabin 2, so as to ensure that the nitrogen in the sealed insulation cabin 2 is relatively positive and constant pressure; the integrated photovoltaic storage machine 4 includes a storage battery 7 and a sealed insulation cabin heat exchanger 8, both of which are placed in the sealed insulation cabin 2; the air supply unit 6 is placed outside the sealed insulation cabin 2; the sealed insulation cabin 2 is installed on the outer wall of the house, and has a mutual insulation effect with the house. The photovoltaic water electrode sensible heat latent heat storage boiler 5 is placed in the basement 9 or the insulation cellar. The photovoltaic module 3 is installed on the roof or around the house, and the photovoltaic module output end 10 is connected to the DC input end 11 of the integrated photovoltaic storage machine through the cable through the sealed insulation cabin 2, and is connected to the photovoltaic water electrode sensible heat latent heat storage boiler power supply low-frequency converter 12 through the basement 9, and the energy is provided by 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 insulation cabin 2, the air compressor air inlet 16 is connected to the atmosphere, the air compressor exhaust end is embedded with a nitrogen-oxygen separation membrane module 14, and the compressed gas of the air compressor 13 is connected to the sealed insulation cabin 2 through the nitrogen outlet 17. At this time, the compressed gas of the air compressor 13 provides a relatively positive pressure nitrogen of about 1 atmosphere for the sealed insulation cabin through the nitrogen-oxygen separation membrane module 14 and the nitrogen outlet 17, which solves the heat dissipation of the equipment in the sealed insulation cabin 2, active fire prevention, dust and derating of the equipment.

[0045] The compressed gas is separated into oxygen through the nitrogen-oxygen separation membrane module 14 and compressed into the floating roof oxygen tank 15 connected thereto through the oxygen outlet 18 . The floating roof oxygen tank 15 provides oxygen demand for life through the oxygen delivery 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 touch screen 21 and a communication interface 22 embedded therein.

[0047] The communication interface 22 is connected to the integrated photovoltaic and storage machine controller 23, the photovoltaic water electrode sensible heat and latent heat storage boiler controller 24, the environmental monitor 25, and all sensors through the communication cable. The main controller 1 reads the data of all sensors, the environmental monitor 25, the integrated photovoltaic and storage machine controller 23, and the photovoltaic water electrode sensible heat and latent heat storage boiler controller 24 through the communication interface 22 and the communication cable, and controls the integrated photovoltaic and storage machine 4 and the photovoltaic water electrode sensible heat and latent heat storage boiler 5 through the communication interface 22 and the communication cable to ensure the optimal power and temperature supply.

[0048] Furthermore, the sealed insulation cabin heat exchanger 8 also includes a heat exchanger water inlet pipe 27 and a heat exchanger water outlet pipe 28. The sealed insulation cabin heat exchanger 8 is placed in the upper part of the sealed insulation cabin 2. The heat exchanger water inlet pipe 27 passes through the sealed insulation cabin 2 and is connected to the outside water source. The heat exchanger water outlet pipe 28 is connected to the photovoltaic water electrode sensible heat latent heat storage boiler water inlet 29. The local water source at high altitude is mostly glacier meltwater, and the water temperature is below 10°C all year round. The sealed insulation cabin heat exchanger 8 uses the low-temperature water through the heat exchanger water inlet pipe 27 to exchange heat with the nitrogen in the sealed insulation cabin 2, which not only reduces the temperature inside the sealed insulation cabin 2 to ensure the normal operation of the equipment, but also increases the temperature of the water entering the photovoltaic water electrode sensible heat latent heat storage boiler 5 through the heat exchanger water outlet pipe 28 through the photovoltaic water electrode sensible heat latent heat storage boiler water inlet 29, preheating the water of the photovoltaic water electrode sensible heat latent heat storage boiler 5 and reducing the power consumption of the photovoltaic water electrode sensible heat 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 is supplied to the air compressor 13, the photovoltaic and energy storage integrated machine controller 23, the photovoltaic water electrode sensible heat latent heat storage boiler controller 24 and the electricity for daily use through the cable 31 via the AC output terminal 30 of the photovoltaic and energy storage integrated machine. The minimum remaining power of the main controller 1 Under the control of the allocation strategy based on the principle of priority 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 heat latent heat storage boiler 5 has the functions of water heating, heat preservation, and phase change heat storage, and is placed in the basement 9 or the heat preservation cellar. Due to the heating principle of the electrode hot water boiler, the voltage and current release a large amount of heat energy through the water body with set conductivity, 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 resistor, the electrical energy is 100% converted into heat with high efficiency, and there is almost no heat loss.

[0051] The photovoltaic water electrode sensible heat 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 a photovoltaic water electrode sensible heat latent heat storage boiler water inlet 29, a domestic heating water outlet 46 and a domestic heating return water inlet 47.

[0053] The glacier meltwater is heat exchanged through the heat exchanger outlet pipe 28 and enters the water body 45 of the photovoltaic water electrode sensible heat and latent heat storage boiler 5 through the photovoltaic water electrode sensible heat and latent heat storage boiler water inlet 29. The water body 45 heated by the photovoltaic water electrode sensible heat and latent heat storage boiler 5 is then heated and supplied to domestic use through the domestic heating outlet 46 and the 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 generator 42. The phase change material sealed container 40 is filled with the phase change material 41, and the phase change heat generator 42 is placed in the phase change material 41. The phase change material sealed container 40 is made of insulating material, and the water body of the photovoltaic water electrode sensible heat latent heat storage boiler 5 is separated from the phase change material 41. Since 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, so the phase change material sealed container 40 is placed in the water body 45 of the photovoltaic water electrode sensible heat 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 the water body 45 is higher than the melting point of the phase change material 41, the phase change material 41 absorbs the heat of the water body 45 through the upper temperature control valve 43, the lower control valve 44, and the phase change heat exchanger 42, and stores the relatively high temperature heat. When the temperature of the water body 45 is lower than the living heating temperature, under controlled conditions, the phase change material 41 releases heat to the water body 45 through the upper temperature control valve 43, the lower control valve 44, and the phase change heat exchanger 42 to increase the temperature of the water body 45. Since the phase change material 41 and the water body 45 exchange temperature through the phase change heat exchanger 42 and the insulation of the insulation material, the heat can be stored for a long time. Among them, the melting point of the phase change material 41 is higher than the living 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 driving motor 37, a transmission screw 38 and a photovoltaic water electrode sensible heat latent heat storage boiler controller 24. The movable water electrode 36 is connected to the transmission screw 38 through a threaded buckle. Under the action of the rotation of the transmission screw 38 driven by the driving motor 37, the movable water electrode 36 is controlled to move horizontally, and the distance between the movable water electrode 36 and the fixed water electrode 35 is changed. Since the product of the volume of water and the resistivity 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 value, and vice versa. Therefore, the photovoltaic water electrode sensible heat latent heat storage boiler controller 24 can determine the water resistance value by detecting the relative distance between the movable water electrode 36 and the fixed water electrode 35, and according to the data of the main controller 1 and the photovoltaic power generation maximum power point tracking strategy, the relative distance between the movable water electrode 36 and the fixed water electrode 35 is controlled and adjusted in real time to achieve photovoltaic power generation maximum power point tracking and ensure the highest efficiency of photovoltaic power generation.

[0059] Thus, the movable water electrode 36 and the fixed water electrode 35 are connected to the low-frequency converter 12 of the power supply of the photovoltaic water electrode sensible heat and latent heat storage boiler, and the power of the photovoltaic module output terminal 10 is directly absorbed, so that the photovoltaic module 3 can almost directly supply power to the water electrode heat storage boiler 5. Among them, the photovoltaic water electrode heat storage boiler 5 is similar to the traditional AC water electrode boiler using a 50Hz power frequency switching time of 0.2 seconds, except that the AC power frequency constant voltage output of the traditional AC water electrode boiler is changed to directly follow the change of photovoltaic power generation voltage and the low-frequency converter 12 of the power supply of the photovoltaic water electrode sensible heat and latent heat storage boiler uses a lower frequency electronic or mechanical switch to switch the polarity of the water electrode, cancel the photovoltaic DC to AC inverter link to reduce costs and reduce losses. Thus, while ensuring that the movable water electrode 36 and the fixed water electrode 35 are not polarized, the switching time of the low-frequency converter 12 of the power supply of the photovoltaic water electrode sensible heat and latent heat storage boiler is reduced, and the photovoltaic power generation efficiency is improved.

[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 according to the optimal objective 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 resistor 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 maximum power point of photovoltaic Right now , thereby achieving the photovoltaic maximum power point of the photovoltaic water electrode sensible heat latent heat storage boiler 5 Tracking, new energy is maximized.
