Description

Technical Field

[0001] This application relates to the field of energy and temperature control technology for lunar bases, and in particular to an integrated intelligent control system for storage and heat extraction for lunar bases. Background Technology

[0002] The lunar surface environment is extremely harsh, with a day-night cycle lasting approximately 15 days and extreme temperature variations exceeding 300°C. Lacking atmospheric protection, it faces intense cosmic radiation and the threat of micrometeoroids. One of the core requirements for establishing a lunar base and achieving long-term habitation is maintaining a stable, comfortable temperature environment for astronauts in enclosed cabins. This is a crucial prerequisite for ensuring the astronauts' survival and health, improving work efficiency, and ensuring the stable operation of equipment.

[0003] Current energy supply solutions for lunar bases mainly fall into two categories: small nuclear fission reactors and solar energy utilization. Among them, solar energy has become a key research direction due to its advantages of being readily available in situ and clean and pollution-free. However, the intermittent light characteristics of lunar day and night result in significant spatiotemporal discontinuities in solar energy supply. Therefore, a highly efficient energy storage system is necessary to achieve continuous energy supply and thus ensure the stable maintenance of a comfortable temperature.

[0004] Among existing Earth solar thermal power generation technologies, linear Fresnel collectors have been widely used due to their simple structure, low cost, and strong optical performance tolerance. They collect heat by reflecting and focusing sunlight onto a heat absorber tube using a plane mirror array. However, the Earth's environment differs greatly from the Moon's environment. Existing linear Fresnel collectors cannot be directly adapted to the Moon's unique environment, such as high vacuum, extreme temperature differences, and low gravity, making it difficult to meet the precise temperature control requirements for human comfort in lunar cabins.

[0005] Regarding energy storage media, commonly used Earth-based energy storage materials (such as molten salt and phase change materials) would require Earth-Moon transportation for application in lunar bases, resulting in extremely high transportation costs and resupply difficulties. Utilizing lunar resources is key to solving this problem. Sintered lunar regolith or lunar rocks, being the most abundant resources on the lunar surface, possess stable heat transfer properties. Meanwhile, abundant water ice resources have been discovered in the lunar polar regions. Water ice has high latent heat of phase change and high energy density, enabling efficient heat storage. However, water ice alone is susceptible to phase change failure due to extreme temperature differences, and sintered lunar regolith alone has a slow heat storage rate. Currently, there is no complete technical solution for lunar base temperature control that combines water ice with sintered lunar regolith or lunar rocks as a composite material, in conjunction with linear Fresnel thermal collectors, with the core objective of maintaining a comfortable human body temperature.

[0006] In terms of temperature control, existing spacecraft temperature control technologies are mostly designed based on the Earth orbit space environment, with the core focus on ensuring the operating temperature of equipment. They are not specifically adapted to the larger heat load fluctuations and longer periods of energy storage without sunlight required by lunar bases, and they cannot accurately match the control requirements of the human body's comfortable temperature range.

[0007] Therefore, there is an urgent need to develop an integrated heat collection, heat storage, and temperature control system that is adapted to the extreme lunar environment, based on in-situ resource utilization, and with human comfort temperature as the control target, to solve the problem of temperature assurance for long-term stays on the lunar base. Summary of the Invention

[0008] The purpose of this application is to provide an integrated intelligent control system for heat storage and extraction for lunar bases. This system can achieve efficient heat collection through linear Fresnel collectors, in-situ energy storage using a composite water-ice-sintered lunar soil, and precise temperature control. This system can maintain the temperature of the living and working compartments for astronauts on the lunar base within a comfortable range, reduce dependence on Earth-Moon transportation, improve the system's economy and reliability, and ensure the feasibility of long-term stays on the lunar base.

[0009] To achieve the above objectives, this application provides an integrated intelligent control system for storage and heat extraction for a lunar base, comprising: a linear Fresnel heat collection subsystem, a water ice-sintered lunar soil composite heat storage subsystem, and a temperature control subsystem; The linear Fresnel solar collector system is used to collect solar energy and convert it into thermal energy. The output of the linear Fresnel solar collector system is connected to the input of the water ice-sintered lunar soil composite thermal storage system. The water-ice-sintered lunar soil composite thermal energy storage subsystem is used to store and release thermal energy through the water-ice energy storage medium. The output end of the water-ice-sintered lunar soil composite thermal energy storage subsystem is connected to the temperature control subsystem. The temperature control subsystem, located within the sealed cabin of the lunar base, is used to adjust the heat collection status of the linear Fresnel heat collection subsystem and the heat extraction rate of the water ice-sintered lunar soil composite heat storage subsystem according to the light intensity and cabin temperature, so as to maintain the cabin temperature of the sealed cabin of the lunar base within a preset temperature range.

[0010] According to the specific embodiments provided in this application, this application has the following technical effects: This application employs an integrated system comprising a linear Fresnel solar collector subsystem, a water-ice-sintered lunar soil composite thermal storage subsystem, and a temperature control subsystem. The linear Fresnel solar collector subsystem effectively collects solar energy and converts it into thermal energy, providing a stable heat source for the system and solving the problem of discontinuous solar energy supply in time and space on the moon. The water-ice-sintered lunar soil composite thermal storage subsystem stores and releases thermal energy through water-ice energy storage medium, ensuring effective retention and on-demand supply of thermal energy. The temperature control subsystem is located within the sealed cabin of the lunar base and can adjust the heat collection state of the linear Fresnel solar collector subsystem and the heat extraction rate of the composite thermal storage subsystem according to the light intensity and cabin temperature, thereby maintaining the cabin temperature stably within a preset temperature range. This provides a stable and comfortable temperature environment for astronauts living and working on the lunar base, ensuring their survival, health, and work efficiency, ensuring the stable operation of equipment within the cabin, and effectively solving the temperature assurance problem for long-term stays on the lunar base.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] In one exemplary embodiment, an integrated intelligent control system for heat storage and extraction for a lunar base is provided, comprising: a linear Fresnel heat collection subsystem, a water ice-sintered lunar soil composite heat storage subsystem, and a temperature control subsystem, to achieve integrated operation of heat collection, heat storage, heat extraction, and temperature control. The core control objective is to maintain the cabin temperature of the closed compartment of the lunar base where astronauts live and work within a preset temperature range (20°C-26°C), which is the human comfort temperature range.

[0016] The following sections will introduce each subsystem in detail.

[0017] (1) Linear Fresnel heat collector system.

[0018] The linear Fresnel solar collector system is used to collect solar energy and convert it into thermal energy. The output of the linear Fresnel solar collector system is connected to the input of the water ice-sintered lunar soil composite thermal storage system.

[0019] like Figure 1 As shown, the linear Fresnel heat collection subsystem includes: a plane mirror array 1-1, a secondary reflector 1-2, a heat absorption tube 1-3, a tracking drive mechanism 1-4, and a thermal insulation layer 1-5.

[0020] The plane mirror array 1-1 consists of multiple linear plane mirrors, each with an independently adjustable angle. Each linear plane mirror is made of lightweight reflective material (aluminum-based reflective material is used in this embodiment), and the surface of each linear plane mirror is coated with an anti-radiation and anti-corrosion coating (SiO2 coating is used in this embodiment) to adapt to the high vacuum and strong radiation environment of the moon and improve its service life.

[0021] The tracking drive mechanism 1-4 is connected to the plane mirror array 1-1 and is used to adjust the angle of each linear plane mirror in the plane mirror array 1-1 according to the solar azimuth angle.

[0022] Secondary reflector 1-2 is positioned above the focusing area of ​​plane mirror array 1-1 to refocus the sunlight reflected by plane mirror array 1-1 onto the surface of heat absorber tube 1-3, thereby increasing the heat collection intensity.

[0023] The heat absorber tube 1-3 is filled with a heat transfer medium and wrapped with an insulation layer 1-5. The heat absorber tube 1-3 is made of a high-temperature resistant alloy, and the heat transfer medium is either high-temperature thermal oil or liquid metal (such as a sodium-potassium alloy), suitable for the heat transfer requirements of the extreme lunar temperature environment, ensuring stable heat transfer to maintain a comfortable temperature. The insulation layer 1-5 is made of a thermal insulation material prepared from sintered lunar soil, used to reduce heat loss of the heat absorber tube 1-3 in the extreme lunar environment and ensure heat collection efficiency.

[0024] The linear Fresnel solar collector subsystem 1 achieves precise focusing and heat collection of sunlight through a plane mirror array 1-1 and a secondary reflector 1-2, and the tracking drive mechanism 1-4 adapts to the changes in the lunar solar azimuth angle.

[0025] (2) Water-ice-sintered lunar soil composite thermal storage subsystem.

[0026] The water-ice-sintered lunar soil composite thermal energy storage subsystem is used to store and release thermal energy through the water-ice energy storage medium. The output end of the water-ice-sintered lunar soil composite thermal energy storage subsystem is connected to the temperature control subsystem.

[0027] like Figure 1 As shown, the water-ice-sintered lunar soil composite thermal storage subsystem includes a thermal storage chamber 2-1, a water-ice energy storage medium 2-2, a heat transfer coil 2-3, and a heat extraction coil 2-4.

[0028] The thermal storage chamber 2-1 is located in the underground area below or to the side of the enclosed chamber 4 of the lunar base, and uses the lunar surface soil to achieve auxiliary heat insulation.

[0029] Water ice energy storage medium 2-2, which is filled inside the heat storage chamber 2-1, is prepared by mixing water ice extracted in situ on the moon with sintered lunar soil. It has excellent heat storage performance and thermal stability and can meet the heat source requirements for maintaining a comfortable temperature during the 15-day lunar night.

[0030] Both the heat transfer coil 2-3 and the heat extraction coil 2-4 are embedded inside the water-ice energy storage medium 2-2, and their materials are the same as those of the heat absorption tube 1-3.

[0031] The input end of the heat transfer coil 2-3 is connected to the output end of the heat absorption coil 1-3, realizing the transfer and storage of heat collected by the linear Fresnel heat collection subsystem to the water-ice energy storage medium 2-2. The output end of the heat extraction coil 2-4 is connected to the temperature control subsystem, realizing the release of heat stored in the water-ice energy storage medium 2-2.

[0032] The thermal storage chamber 2-1 is externally equipped with an insulating shell 2-5. The insulating shell 2-5 adopts a multi-layered insulating structure. The inner layer of the multi-layered insulating structure is an insulating brick made of sintered lunar soil, and the outer layer is a metal protective layer. The insulating shell 2-5 is used to isolate the extreme temperature difference on the lunar surface from the interior of the thermal storage chamber 2-1, ensure the temperature stability of the water ice energy storage medium 2-2, and provide a continuous heat source for maintaining a comfortable temperature.

[0033] The water-ice-sintered lunar soil composite thermal energy storage subsystem uses a composite energy storage medium prepared by mixing lunar in-situ water ice and sintered lunar soil. Combined with heat transfer coil 2-3 and heat extraction coil 2-4, it achieves efficient and long-term storage and release of heat, reducing the cost of Earth-Moon transportation.

[0034] (3) Temperature control subsystem.

[0035] The temperature control subsystem, located within the sealed cabin of the lunar base, is used to adjust the heat collection status of the linear Fresnel heat collection subsystem and the heat extraction rate of the water ice-sintered lunar soil composite heat storage subsystem according to the light intensity and cabin temperature, so as to maintain the cabin temperature of the sealed cabin of the lunar base within a preset temperature range (20℃-26℃).

[0036] like Figure 1 As shown, the temperature control subsystem includes: heat extraction pipeline 3-1, heat exchange device 3-2, circulating pump 3-3, heat dissipation unit 3-4, temperature sensor 3-5, light sensor 3-6, data acquisition module 3-7, and controller 3-8.

[0037] The heat extraction pipe 3-1 is connected to the output end of the heat extraction coil 2-4.

[0038] The heat exchange device 3-2 is located inside the sealed cabin 4 of the lunar base and is connected to the heat extraction pipeline 3-1. It is used to realize the heat exchange between the water ice energy storage medium 2-2 and the air inside the sealed cabin 4 of the lunar base. The heat exchange device 3-2 adopts a finned heat exchanger to increase the contact area with the air inside the cabin and improve the heat exchange efficiency. The fins of the finned heat exchanger are made of lightweight metal material to ensure that the cabin temperature responds quickly to the control requirements.

[0039] The circulating pump 3-3 is installed on the heat extraction pipeline 3-1 and is used to drive the heat transfer medium to circulate.

[0040] Heat dissipation unit 3-4 is connected to the exhaust port of the sealed cabin 4 of the lunar base. It is used to dissipate excess heat inside the sealed cabin of the lunar base. That is, when the temperature inside the sealed cabin 4 of the lunar base exceeds the upper limit of the human comfort range, excess heat is dissipated to ensure that the temperature drops back to the comfort range.

[0041] Temperature sensor 3-5 is installed inside the sealed compartment 4 of the lunar base to collect the compartment temperature. Temperature sensor 3-5 is a platinum resistance temperature sensor. In addition, temperature sensors can also be installed inside the water ice energy storage medium 2-2 (to monitor the heat storage status in real time), inside the heat transfer coil and heat extraction coil (to monitor the heat transfer status), and outside the compartment (to collect the ambient reference temperature).

[0042] Light sensors 3-6 are used to collect the intensity of sunlight.

[0043] The data acquisition module 3-7 is connected to the temperature sensor 3-5, the light sensor 3-6, and the controller 3-8 respectively, and is used to acquire the cabin temperature and light intensity, and transmit the cabin temperature and light intensity to the controller 3-8.

[0044] The controller 3-8 is connected to the linear Fresnel solar collector subsystem, the water-ice-sintered lunar soil composite thermal storage subsystem, the circulating pump 3-3, the heat dissipation unit 3-4, and the data acquisition module 3-7, respectively. It is used to divide the lunar daytime and lunar nighttime operating conditions according to the light intensity, and generate control commands based on the cabin temperature and light intensity to adjust the action of the tracking drive mechanism 1-4, the speed of the circulating pump 3-3, and the start / stop status of the heat dissipation unit 3-4, thereby adjusting the heat collection status of the linear Fresnel solar collector subsystem and the heat extraction rate of the water-ice-sintered lunar soil composite thermal storage subsystem.

[0045] The temperature control subsystem achieves precise regulation of the cabin temperature through the coordinated operation of heat exchange device 3-2, heat dissipation unit 3-4, sensor and controller 3-8; controller 3-8 regulates the operation of each subsystem in real time according to the cabin temperature and light intensity.

[0046] Furthermore, the controller 3-8 has a built-in lunar solar azimuth angle prediction model, which is constructed based on a lightweight machine learning algorithm (such as the random forest algorithm). The lunar solar azimuth angle prediction model is used to predict the solar azimuth angle based on the light intensity during lunar daytime operation and generate tracking drive control commands to control the tracking drive mechanism 1-4 to adjust the angle of each linear plane mirror in the plane mirror array 1-1.

[0047] Furthermore, the controller 3-8 uses a PID temperature control algorithm to calculate the error between the cabin temperature and the set target value, and outputs an adjustment control signal based on the error to adjust the speed of the circulating pump 3-3 and the start / stop status of the heat dissipation unit 3-4, thereby controlling the cabin temperature within the range of 20℃ to 26℃.

[0048] In this system, controller 3-8 classifies operating conditions based on the light intensity data collected by light sensor 3-6. The specific operating logic is as follows: (1) Lunar daytime operating conditions (light intensity ≥ 500W / m) 2 The controller 3-8 starts the tracking drive mechanism 1-4, adjusts the angle of the plane mirror array 1-1, and the linear Fresnel heat collection subsystem 1 begins to collect heat. After the heat transfer medium absorbs heat, it is transferred to the heat storage chamber 2-1 through the heat absorption pipe 1-3 and the heat transfer coil 2-3. The heat is then transferred to the water ice energy storage medium 2-2 for storage through the heat transfer coil 2-3. The water ice rapidly undergoes phase change to store heat, and the sintered lunar soil adsorbs and slowly releases some of the heat. At the same time, the controller 3-8 monitors the chamber temperature in real time. If the chamber temperature is below 20℃, the speed of the circulation pump 3-3 is increased to increase the heat extraction rate and raise the chamber temperature. If the chamber temperature is above 26℃, the electric valve of the heat dissipation unit 3-4 is immediately opened to discharge excess heat and ensure that the chamber temperature drops back to the comfortable range of 22℃±2℃. (2) Working conditions under moonlight (light intensity < 500W / m) 2 When the linear Fresnel heat collection subsystem stops working, the controller 3-8 controls the circulation pump 3-3 to continue running. The heat stored in the water-ice energy storage medium 2-2 (latent heat of water-ice phase change and heat storage of sintered lunar soil) is transferred to the heat exchange device 3-2 through the heat extraction coil 2-4 and heat extraction pipeline 3-1 to heat the cabin. The controller 3-8 monitors the cabin temperature in real time and precisely controls the heat supply by adjusting the speed of the circulation pump 3-3. If the temperature is below 20℃, the speed is increased to increase the heat supply. If the temperature is above 26℃, the heat dissipation unit 3-4 is activated to always keep the cabin temperature stable within the comfort range.

[0049] In this embodiment, through the coordinated operation of the above systems, the temperature inside the closed compartment 4 of the lunar base can be stably maintained within the optimal comfort range of 22℃±2℃, meeting the temperature requirements for astronauts' long-term living and working. During the lunar day, the linear Fresnel heat collection subsystem can efficiently collect heat, and the water ice energy storage medium 2-2 can achieve long-term heat storage, fully meeting the continuous energy and heat supply requirements for 15 days of lunar night, significantly reducing dependence on Earth-Moon transportation, improving the economy and reliability of the system, and providing core temperature protection for long-term stay at the lunar base.

[0050] Compared with the prior art, this application has the following beneficial effects: (1) Adaptable to the extreme lunar environment and precisely matched to the comfort temperature requirements: The linear Fresnel heat collection subsystem of this application adopts a reflector with anti-radiation and anti-wear coating and in-situ prepared heat insulation material. The linear Fresnel heat collection subsystem utilizes underground area auxiliary heat insulation. The temperature control subsystem is equipped with a high-efficiency heat exchange device 3-2 and a heat dissipation unit 3-4, which fully adapts to the characteristics of the lunar environment of high vacuum, strong radiation and extreme temperature difference. The stable structure of sintered lunar soil in the water ice energy storage medium can protect the water ice from damage by the extreme environment. The high latent heat of phase change of water ice improves the heat storage efficiency. At the same time, the core control target is the human comfort temperature, which combines operational reliability and comfort. (2) Reduce transportation costs and improve sustainability: Key components such as water ice energy storage medium 2-2, secondary reflector 1-2 materials, and heat insulation materials are all prepared using lunar in-situ resources, eliminating the need for transportation from Earth and significantly reducing the cost of Earth-Moon transportation. At the same time, it makes full use of lunar polar water ice resources and widely distributed lunar soil resources, improving the system's economic efficiency and the sustainability of long-term lunar base stay. (3) High heat collection and storage efficiency, ensuring continuous and stable heat source: The linear Fresnel heat collection subsystem achieves precise focusing of sunlight through the tracking drive mechanism 1-4 and the secondary reflector 1-2, thereby improving heat collection efficiency; the water ice energy storage medium 2-2 combines the high latent heat of water ice phase change with the excellent thermal stability of sintered lunar soil, which can quickly and efficiently store heat during the lunar day. The sintered lunar soil can also slow down the phase change rate of water ice, achieving long-term heat storage and providing a sufficient and stable heat source for the continuous maintenance of comfortable temperature during the 15 days of lunar night. (4) Precise and stable temperature control to meet human comfort needs: The temperature control subsystem takes the human comfort temperature of 20℃-26℃ as the core target. Combined with the cabin temperature and the lunar day-night cycle, it realizes intelligent control of heat collection, heat storage and heat extraction processes. Through the coordinated work of heat exchange device 3-2 and heat dissipation unit 3-4, the temperature inside the closed cabin 4 of the lunar base can be stably maintained in the optimal comfort range of 22℃±2℃, which completely solves the problem of temperature guarantee for astronauts' life and work in the extreme environment of the moon and improves the feasibility of long-term stay in the lunar base.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope.
