Description

TECHNICAL FIELD

[0001] The invention relates to a system for creating individualized atmospheres within a sports training facility.

[0002] In another aspect, the invention also relates to a use for creating individualized atmospheres in a hotel.PRIOR ART

[0003] Training at high altitude is often done by athletes, especially cyclists, to improve their endurance and performance. The concept is based on the body's natural response to hypoxia, a condition wherein in which the body or part of it is deprived of an adequate supply of oxygen. At high altitudes, the air pressure is lower, which means that less oxygen is absorbed by the blood in the lungs. To compensate for this, the body produces more red blood cells to increase oxygen uptake. Traditionally, athletes would go to a training camp held at high altitude, where they would stay in mountainous areas for weeks at a time.

[0004] The popularity of training camps held at high altitudes in sports training, especially in disciplines such as cycling, has increased considerably in recent years. In the past, cyclists traditionally attended a training camp held at high altitude for 3 to 4 weeks before major competitions, wherein such training periods were usually scheduled twice a year. However, nowadays, some athletes spend more time at high altitudes, leading them to choose to spend the night in a traditional altitude room or tent instead of mountainous areas.

[0005] Both staying in the mountains (the traditional high-altitude training camp) and sleeping in an altitude room or tent have various disadvantages.

[0006] One of the limitations of training in mountainous areas is the lack of individual adjustments in training plans. Athletes exhibit varying responses to different altitudes, with some benefiting more from training at higher altitudes than others. Additionally, training is almost by definition intensive, which is not always optimal for certain training regimes, such as LHTL (Live High, Train Low) where the emphasis is on generally lower training intensity.

[0007] A disadvantage of the classic hypoxic bedrooms is that athletes are isolated for weeks because they have to spend as much time as possible in their hypoxic bedrooms to maximize exposure to low oxygen levels. This is detrimental to social cohesion and mental health. Athletes find this stultifying and their motivation decreases.

[0008] Such systems are already described in a general context in WO202418779, US2006199518, and JP2022171200, where a hypoxic room for sports training is described, but these are individual solutions not suitable for longer stays.

[0009] To overcome these limitations and provide a more effective, individualized, and socially conducive environment for high-altitude training, there is a need for solutions that take into account the specific needs of individual cyclists while addressing the drawbacks of traditional methods. The present invention aims to at least find a solution to some of the above-mentioned problems or disadvantages. The aim of the invention is to provide a system which eliminates these disadvantages.SUMMARY OF THE INVENTION

[0010] In a first aspect, the present invention relates to a system according to claim 1. Preferred embodiments of the method are set out in claims 2 to 14.

[0011] The invention relates to a system for creating individualized atmospheres within a sports training facility, such as a hotel. The system includes a ventilation system and a hypoxic system with a membrane nitrogen generator for filtering an incoming airflow to produce nitrogen by means of semi-permeable membranes that separate nitrogen gas from the incoming airflow. This creates an atmosphere with a reduced oxygen content. This simulates different altitudes and allows athletes to do altitude training within the facility. The system includes one or more enclosed spaces, where the oxygen concentration in each room is adjustable, allowing individual training needs to be accommodated. The system is also equipped with sensors to monitor the oxygen level and the airtight separation between the compartments in the spaces. The system offers various advantages, including promoting social cohesion and mental health of the residents, enabling individual adjustment of the oxygen level, and efficient use of the generated air through reuse in the membrane nitrogen generator.

[0012] An objective of the invention is to provide a system that simulates oxygen-poor air from different altitudes and delivers it to a user for contactless inhalation in accordance with a hypoxic training or therapy protocol.

[0013] Another objective of the invention is to provide a facility for hypoxic training and / or therapy.

[0014] Another objective of the present invention is to provide a system for depleting the oxygen content of the air.

[0015] Another objective of the invention is to develop versatile spaces for athletes that are tailored to their individual needs.

[0016] Another objective of the invention is to provide altitude training benefits to athletes without the need to travel to higher altitude areas.

[0017] Another objective of the invention is to adjust the hypoxic atmosphere to the individual needs and preferences of guests.

[0018] Another objective of the invention is to maximize the length of stay in a hypoxic atmosphere.

[0019] Another objective of the invention is to promote social interactions and avoid a sense of isolation.

[0020] In a second aspect, the present invention relates to a use according to claim 15.

[0021] This use results in an advantageous hotel / sports facility equipped with environments tailored to the individual needs of athletes. It offers athletes the opportunity to benefit from the advantages of altitude training without having to physically travel to higher altitude areas. The adjustable hypoxic atmosphere can be tailored to the individual needs and preferences of guests, allowing them to enjoy customized training programs designed to enhance their performance and well-being. Moreover, by also bringing common spaces into a hypoxic atmosphere, the length of stay in a hypoxic atmosphere is maximized and social interactions are promoted, thereby avoiding the feeling of isolation.DESCRIPTION OF THE DRAWINGS

[0022] Figures 1 and 2 each show a schematic top view of a system for creating individualized atmospheres within a sports training facility, wherein the system is provided according to an embodiment of the present invention.DETAILED DESCRIPTION

[0023] Unless otherwise defined, all terms used in the description of the invention, including technical and scientific terms, have the meanings as commonly understood by a person skilled in the art to which the invention pertains. For a better understanding of the description of the invention, the following terms are explained explicitly.

[0024] In this document, "a" and "the" refer to both the singular and the plural, unless the context presupposes otherwise. For example, "a segment" means one or more segments.

[0025] When the term "around" or "about" is used in this document with a measurable quantity, a parameter, a duration or moment, and the like, then variations are meant of approx. 20% or less, preferably approx. 10% or less, more preferably approx. 5% or less, even more preferably approx. 1% or less, and even more preferably approx. 0.1% or less than and of the quoted value, insofar as such variations are applicable in the described invention. However, it must be understood that the value of a quantity used where the term "about" or "around" is used, is itself specifically disclosed.

[0026] The terms "comprise," "comprising," "consist of," "consisting of," "provided with," "include," "including," "contain," "containing," are synonyms and are inclusive or open terms that indicate the presence of what follows, and which do not exclude or prevent the presence of other components, characteristics, elements, members, steps, as known from or disclosed in the prior art.

[0027] The terms "hypoxic atmosphere" or "hypoxic environment" in the present invention refer to an artificially created environment where the oxygen concentration is lowered to simulate conditions similar to those at high altitude. It concerns an environment where the concentration of oxygen is lower than at sea level. In the present invention, "normobaric hypoxia" is applied, which refers to a condition where there is a relatively lower than normal level of oxygen available to the tissues, but where the ambient air pressure remains within normal limits. This occurs, for example, at high altitudes where the air is thinner and the partial pressure of oxygen is lower than at sea level, but where the total atmospheric pressure still remains within normal limits. In normobaric hypoxia, people experience reduced oxygen availability without the total air pressure significantly decreasing.

[0028] The terms "normoxic atmosphere" or "normoxic environment" in the present invention refer to all atmospheric conditions where the oxygen concentration is within the normal physiological limits for human functioning. For humans, a normoxic atmosphere is typically an environment where the oxygen concentration is approximately 20.9%, which corresponds to the oxygen concentration in the atmosphere at sea level. In such environments, people can breathe and function normally without experiencing hypoxia (too little oxygen) or hyperoxia (too much oxygen).

[0029] The terms "oxygen-rich permeate" and "oxygen-poor retentate" are terms used in the context of membrane separation technology, such as in the separation of oxygen and nitrogen using membranes. "Oxygen-rich permeate" refers to the portion of the airflow that has penetrated through the membrane and contains a higher concentration of oxygen than the original airflow. The permeate is the separated gas that has passed through the membrane and is collected on the permeate side of the membrane. "Oxygen-poor retentate" refers to the portion of the airflow that has not penetrated through the membrane and remains on the retentate side of the membrane. The retentate contains a lower concentration of oxygen than the original airflow because some of the oxygen has penetrated through the membrane and is now in the permeate.

[0030] The terms "user" and "athlete" are synonyms and should be understood in the present context as all persons using the facilities of the invention, including trainers, coaches, medical professionals, support staff, professional and amateur athletes including cyclists, runners, and other athletes.

[0031] The term "equivalent altitude" in the present invention indicates the altitude that is simulated by a reduced oxygen concentration, resulting in an environment that mimics the physical effects of actually being at that specific altitude.

[0032] Quoting numeric intervals by the endpoints includes all integers, fractions, and / or real numbers between the endpoints, including those endpoints.

[0033] In a first aspect, the invention relates to a system for creating individualized atmospheres within a sports training facility. This system is designed to optimize training conditions for different athletes, taking into account their individual needs, training goals, and preferences. By creating individualized atmospheres, the system can help athletes improve their performance, prevent injuries, and promote recovery processes.

[0034] According to a preferred embodiment, the system is equipped with a ventilation system suitable for creating a normoxic atmosphere, a hypoxic system suitable for creating a hypoxic atmosphere, and one or more enclosed spaces.

[0035] The ventilation system is designed to create a normoxic atmosphere within the facility. This ventilation system ensures adequate airflow and ventilation, making the environment suitable for comfortable stay and training in a normal oxygen environment. The ventilation system preferably includes fans, air ducts, and other components configured to provide a continuous supply of fresh air and maintain air quality.

[0036] The hypoxic system is suitable for creating a hypoxic atmosphere and simulating different altitudes. This hypoxic system uses a membrane nitrogen generator and filters the incoming airflow to produce nitrogen through semi-permeable membranes that separate nitrogen gas from the incoming airflow. As a result, an outgoing filtered airflow with a reduced relative oxygen content is generated. This allows the system to simulate different altitudes, which is beneficial for training in conditions with lower oxygen concentration. An additional advantage over hypobaric hypoxia is that the air pressure remains unchanged, which is energetically (let alone construction-wise) unfeasible in large-scale applications. A further advantage of using a membrane nitrogen generator is that no external nitrogen sources (nitrogen bottles) are needed, which offers strong advantages in terms of safety and logistics.

[0037] The hypoxic system allows athletes to train under varied and controlled hypoxic conditions. Training in a hypoxic atmosphere will improve endurance and increase aerobic capacity. The body responds to the reduced oxygen concentration by stimulating the production of red blood cells and the formation of capillaries, resulting in more efficient oxygen transport to the muscles. This will lead to improved performance and faster recovery, especially in endurance sports. Moreover, the hypoxic system can be adjusted to the individual needs of athletes, allowing them to train at different altitude levels, depending on their training goals and physical condition. This makes the system very versatile and effective for a wide range of athletes and training programs.

[0038] The facility is divided into one or more enclosed spaces, wherein a first space is provided with at least two compartments that can be substantially airtight from each other. The enclosed spaces of the system are crucial for maintaining the desired atmospheric conditions. These spaces provide a controlled environment where the atmosphere can be individually adjusted to the needs of the athletes, creating an optimal training environment.

[0039] The two-part spaces used in the current system are capable of accommodating the user. The spaces are substantially physically separated spaces, where a door and wall construction defines an enclosed space into which the user can enter through the door. Each compartment within a space is also physically separated or separable from each other (airtight), and preferably a door or the like is also placed between each compartment.

[0040] Preferably, the first compartment of the at least two compartments is equipped with sanitary facilities and is designed to be ventilated under a normoxic atmosphere using the ventilation system. To this end, the first compartment is provided with at least one inlet and at least one outlet of the ventilation system. These are configured to ventilate the first compartment under a normoxic atmosphere. By ventilating this compartment under a normoxic atmosphere, optimal air quality and a comfortable environment for the users are ensured. Ventilation under a normoxic atmosphere ensures that there is sufficient oxygen in the air, which is essential for healthy breathing and general well-being. It also prevents the accumulation of unwanted odors, humidity, or harmful substances in the compartment, which can lead to an unpleasant and unhygienic environment. Moreover, good ventilation helps prevent the spread of germs and bacteria. Finally, providing a "normal" ventilation system in the first compartment also provides a built-in safety feature, allowing the entire space to be ventilated when it is not separated into two compartments (airtight).

[0041] Preferably, the second compartment of the at least two compartments is equipped with sleeping, resting, and / or sports facilities and is designed to be ventilated under both a normoxic and an adjustable hypoxic atmosphere, using both the ventilation system and the hypoxic system. To this end, the second compartment is provided with at least one inlet and at least one outlet of the ventilation system, which are configured to ventilate the second compartment under a normoxic atmosphere. In addition, it includes at least one inlet and at least one outlet of the hypoxic system, which are configured to ventilate the second compartment under an adjustable hypoxic atmosphere. This aspect of the system is crucial because it offers athletes the opportunity to train under both normoxic and hypoxic atmospheric conditions, which brings various benefits to their performance and general well-being. Firstly, the second compartment, equipped with sleeping, resting, and / or sports facilities, allows athletes not only to train but also to rest and recover in the same space. This provides an efficient and comfortable training environment where athletes can optimize their physical and mental well-being. Additionally, it is essential that the second compartment is ventilated under both normoxic and hypoxic atmospheric conditions. Ventilation under normoxic conditions ensures optimal air quality and breathing during rest and recovery periods, while ventilation under an adjustable hypoxic atmosphere allows athletes to improve their performance by training under controlled hypoxic conditions. The ability for normal ventilation also allows it to be activated if there are problems with the hypoxic atmosphere, or if there are issues with the user. For example, this can also be linked to a sensor, e.g., via a wearable, of the user, which automatically activates the regular ventilation system at certain alarm settings (heart rate, breathing, oxygen saturation, etc.), and can function as an override for the hypoxic system.

[0042] The division of a space into two compartments, wherein a second compartment primarily functions as a bedroom and is exposed to a hypoxic atmosphere and the first compartment functions as a bathroom and is provided with normal ventilation, offers a specific and targeted approach for the use of this space. The idea of providing the second compartment with a hypoxic atmosphere while the first compartment has normal ventilation will be beneficial from an energy-saving perspective. By this arrangement, the hypoxic atmosphere is limited to the second compartment, meaning that only this specific part needs to be equipped with the necessary equipment and infrastructure to maintain the hypoxic conditions. This results in more efficient use of energy and resources, as the rest of the space does not need to be adapted for the hypoxic atmosphere.

[0043] In particular, the system is configured to automatically switch between normoxic and hypoxic atmospheres, depending on the received instructions for generating a hypoxic atmosphere in one of the spaces. When such instructions are received, the inlet and outlet of the ventilation system in the second compartment of the respective space are closed, while the inlet and outlet of the hypoxic system are opened, allowing a filtered airflow from the membrane nitrogen generator to be supplied to the second compartment. This system provides a unique and individualized training experience by enabling the creation of both normoxic and hypoxic atmospheres within the same facility, allowing athletes to train in environments that are tailored to their specific needs and goals.

[0044] According to a further or alternative embodiment, the n50 value is a maximum of 1.5 m 3< / h, preferably a maximum of 1.0 m 3< / h, and even more preferably a maximum of 0.5 m 3< / h. The n50 value is the amount of air volume that is renewed per hour at a pressure difference of 50 pascals. This is also called the air change rate or leakage rate, expressed relative to the building's internal volume, and can be measured using, for example, a BlowerDoor test. A lower n50 value indicates that the building or ventilation system is more airtight, resulting in less uncontrolled airflows and thus better energy efficiency and comfort.

[0045] According to a further or alternative embodiment, the outlet of the hypoxic system is connected to the membrane nitrogen generator, wherein the air discharged via the outlet of the hypoxic system returns to the membrane nitrogen generator. Returning the discharged air to the membrane nitrogen generator is essential for the efficient functioning of the hypoxic system, and also to ensure a more efficient supply of excess nitrogen, as it provides a continuous airflow and optimal filtration of oxygen to create the desired hypoxic atmosphere.

[0046] The nitrogen production or oxygen depletion is achieved by membrane separation, wherein a membrane nitrogen generator filters the incoming airflow to produce nitrogen through semi-permeable membranes that separate nitrogen gas from the incoming airflow. Thanks to membrane technology, it is possible to efficiently separate oxygen and nitrogen based on their different molecular sizes.

[0047] Dry air is drawn in via the outlet of the second (hypoxic) compartment or a hypoxic space and fed to the membrane nitrogen generator, where a portion of the incoming air flows through the structure of the fibers to the outside of the fibers, a process called permeation. During this process, water, oxygen, and some of the argon pass through the membrane side of the fibers, leaving only nitrogen. This selective permeation process is possible due to the different rates at which molecules can penetrate the fibers: water has a fast penetration, oxygen takes slightly more time, while argon and nitrogen penetrate slowly through the fibers and remain after water and oxygen have been removed. Some of the argon also penetrates, but complete removal would be inefficient. As permeation through the fiber wall occurs, overpressure builds up in the membrane housing, which can clog the fibers and significantly reduce permeation efficiency. To prevent this, there is an opening in the housing, the permeate outlet, through which the exhaust gases, including water, oxygen, and argon, can escape. Carbon dioxide produced by the user during their stay in the hypoxic space settles due to its higher density and is removed from the space via an outlet. Due to its permeability, which is higher than that of oxygen and nitrogen, carbon dioxide penetrates the membrane nitrogen generator faster and is discharged into the atmosphere. Excess moisture will also be removed from the room due to the faster permeability of water vapor through the membrane nitrogen generator.

[0048] Preferably, a compressor or a fan draws air from a hypoxic space or the second (hypoxic) compartment and feeds compressed air via an outlet to the membrane nitrogen generator, where it is separated into oxygen-rich permeate and oxygen-poor retentate. The oxygen-rich permeate is drawn in by a vacuum pump, and the oxygen-poor retentate is discharged via pipes to the inlet in the second (hypoxic) compartment or a hypoxic space to create a hypoxic atmosphere.

[0049] Preferably, oil-free compressors are used instead of oil-lubricated compressors. Although these compressors are more expensive, they guarantee compressed air that is free of oil. The efficiency of these compressors is approximately equal to that of oil-lubricated compressors. By working with oil-free compressors, it is prevented that oil gets between the membrane, which benefits the efficiency and lifespan of the system.

[0050] Preferably, the membrane nitrogen generator includes a set of parallel-connected membrane cells or a single cell that uses hollow, flat, or capillary membranes. The material for the membrane cells is chosen from the group consisting of poly(dimethylsiloxane), also known as PDMS or its copolymer, or poly[1-(trimethylsilyl)-1-propyne], also known as PMSP. Also suitable for use in forming the membranes of the present invention are silicone rubber, natural rubber, carbon, polybutadiene, polystyrene, ethylcellulose, butyl rubber, Teflon-FEP, polyvinyl acetate, poly(2,6-dimethyl phenylene oxide), or poly(methylpentene-1). Suitable for use in forming the membranes is porous polyethylene or polypropylene. Other possible materials will be apparent to one skilled in the art, who will be able to substitute equivalent materials for the materials mentioned here, without departing from the invention.

[0051] Preferably, membrane cells are made with a porous, tubular carrier structure with a permeable flat, capillary, or hollow fiber membranes on the retentate side of the carrier structure, wherein the membranes preferably consist of highly permeable organic, synthetic, ceramic, glass, metal, composite, mineral, or biological material, or combinations thereof in symmetric, asymmetric, or composite form, porous or non-porous. More preferably, the core of the membrane generator is a membrane module with a diameter of approximately 10 cm filled with small hollow polymer fibers. This provides a maximum surface area for processing large gas volumes that are often required. The use of hollow-fiber membranes is further particularly advantageous, as these membranes are highly efficient and allow for rapid separation of air into nitrogen-rich and oxygen-rich fractions. The number and type of hollow-fiber membranes used in the gas separator of the present system depend on the air volume required by the user. It is clear that the larger the enclosed space, the more users, and the greater the exercise undertaken by the users, the larger the required air volume will be and the more (or larger) membrane units will be needed. In some embodiments, there may be multiple membrane generators, wherein a large number of membrane units is required.

[0052] The volume of nitrogen-rich and / or oxygen-rich gas delivered by the system is not specifically limited and depends on the number of users in the atmosphere and the respiratory requirements of the users. In general, the membrane nitrogen generator can deliver 1-50 L / min of nitrogen-rich gas.

[0053] According to a further or alternative embodiment, the system includes multiple enclosed spaces, wherein each inlet and each outlet of the hypoxic system for each of the multiple enclosed spaces is individually connected to the membrane nitrogen generator, and wherein the flow rate of supply of a filtered outgoing airflow for each of the spaces is individually adjustable to create an adjustable hypoxic atmosphere in two or more spaces. This maximizes the duration that the athlete is exposed to a hypoxic atmosphere. It is important to emphasize that each athlete requires individual hypoxic environments, as not every athlete needs the same conditions for optimal performance and adaptation to altitude training. Therefore, it is particularly advantageous that each (hypoxic) space can be adjusted to different hypoxic levels. With the ability to individually adjust the hypoxic environment in each space, athletes can benefit from a tailored approach to altitude training, wherein the intensity and duration of exposure to hypoxia can be adjusted to the specific needs and goals of each individual athlete. This approach not only maximizes the effectiveness of the training but also provides a higher level of comfort and safety for the athletes.

[0054] According to a further or alternative embodiment, the ventilation system is equipped with a valve system configured to regulate the air supply and air exhaust in the one or more spaces and / or compartments according to a user-adjustable atmosphere. A valve system makes it possible to regulate the air supply and air exhaust in different spaces or compartments. Therefore, the air circulation can be adjusted to the user's needs, resulting in a more comfortable and healthier indoor climate. Also, it will improve the energy efficiency of the ventilation system, leading to reduced energy consumption.

[0055] According to a further embodiment, each inlet of the ventilation system is connected to a common air supply of the ventilation system, and each outlet of the ventilation system is also connected to a common air exhaust of the ventilation system. The valve system is provided with at least one valve between each inlet and preferably also outlet of the ventilation system (in the second compartment) and the common air supply and preferably also air exhaust. These valves can be individually activated or deactivated to individually activate or deactivate the airflow to each space or compartment (particularly for the second compartment) within the facility. The purpose of this valve system is thus to provide a controlled and adjustable airflow to each individual space or compartment within the facility. A permanent ventilation system is implemented, which not only ensures a stable oxygen supply but can also control the CO 2 level throughout the system. By being able to regulate each valve individually, users can adjust the ventilation to the specific needs of each space. For example, spaces or compartments with higher occupancy or activity levels can receive increased air supply for better ventilation, while less used spaces can be optimized for energy savings by reducing the air supply. This also takes into account the hypoxic space or the hypoxic (second) compartment, in which a specific hypoxic atmosphere is created. By being able to regulate each inlet and outlet valve individually, the airflow to the hypoxic space can be precisely adjusted to the requirements for maintaining the desired hypoxic environment. This is crucial to ensure the effectiveness of hypoxic training and achieve the desired training results.

[0056] According to a further or alternative embodiment, a sensor is provided in the space, configured to monitor the airtight separation between the compartments in the spaces. The sensor is coupled to the hypoxic system for generating an alarm signal and / or control signal to the hypoxic system for one of the spaces when a broken airtight separation is detected in said one of the spaces and when the hypoxic system provides a filtered airflow to the second compartment of said one of the spaces.

[0057] The alarm signal generated when a broken airtight separation is detected in one of the spaces serves as a warning for a potential failure in the airtight separation. This can alert users and / or operators of the system to a potential issue that requires immediate attention to ensure the safety and efficiency of the system.

[0058] The purpose of the control signal sent to the hypoxic system is to take action based on the detected disturbance. Depending on the configuration, this signal can, for example, be used to automatically shut down the hypoxic system when a broken airtight separation is detected. This helps ensure safety and prevent unintended exposure to hypoxia until the issue is resolved. Preferably, the hypoxic system is automatically shut down, and the ventilation system is activated, with the valve system being controlled to regulate the air supply and exhaust to the spaces and / or compartments.

[0059] Preferably, the sensor is an O 2 sensor, a CO 2 sensor, a pressure sensor, or a humidity sensor that acts as an essential control mechanism to ensure that the airtight separation between the compartments is maintained, which is crucial for the effectiveness of the hypoxic system. More preferably, the hypoxic space and / or compartment is equipped with an oxygen level sensor and an oxygen depletion alarm. The oxygen level sensor continuously measures the oxygen level in the spaces and transmits the data, for example, to a computer-controlled control unit that regulates the performance of the hypoxic system to achieve and maintain the desired air parameters in accordance with the training or therapy protocol.

[0060] Continuous monitoring of the airtight separation ensures that the hypoxic atmosphere in the spaces is accurately maintained, which is essential for effective and consistent hypoxic training. By quickly responding to any leaks or failures in the airtight separation, the quality of the hypoxic environment will be maintained, and users can achieve the desired training results.

[0061] According to a further or alternative embodiment, the system is configured to shut down the hypoxic system when the airtight separation between the first and second compartments is broken. Monitoring of the compartments and spaces is preferably realized in the same way, and more preferably through the aforementioned sensor that monitors the airtight separation between the first and second compartments. When a sensor detects a broken airtight separation, the system generates an alarm signal. This alarm signal can then be used to automatically shut down the hypoxic system. Additionally, the system can be equipped with, for example, actuators capable of shutting down the hypoxic system when necessary. These actuators are activated by the control signal generated when a broken airtight separation is detected. In this way, the hypoxic system is immediately shut down until the airtight separation is restored.

[0062] According to a further or alternative embodiment, at least one sensor per space is provided and configured to monitor an oxygen level per space, wherein each sensor can be coupled with the membrane nitrogen generator to provide feedback on the oxygen levels, wherein the membrane nitrogen generator, based on the feedback for each space, controls the filtered outgoing airflow to the space. Since it is possible to bring each space to a different hypoxic atmosphere, it is desirable to have one sensor per space. This allows the oxygen level in each space to be accurately monitored, enabling any deviations to be quickly detected and corrected. This contributes to maintaining an optimal indoor climate.

[0063] By coupling each sensor to the membrane nitrogen generator, real-time feedback is obtained on the oxygen level in each space. Based on this feedback, the membrane nitrogen generator can adjust the filtered outgoing airflow to each space to maintain the desired oxygen level. This ensures precise and continuous regulation of the atmospheric conditions, which is essential for creating an optimal training or living environment.

[0064] Moreover, this system contributes to more efficient use of resources, as the membrane nitrogen generator only delivers the required amount of filtered outgoing air based on the actual needs of each space. This minimizes waste and increases the efficiency of the system.

[0065] The oxygen level plays a crucial role in the health and safety of the users present in a hypoxic space. A too low oxygen level can lead to a medically unacceptable oxygen deficiency, resulting in reduced cognitive functions, fatigue, and in severe cases, even unconsciousness or death. By monitoring oxygen levels, the system can ensure that sufficient oxygen is available for those present. Although measuring CO 2 levels can also be an alternative for maintaining a healthy indoor climate, oxygen measurement is specifically important in situations where wherein hypoxia poses a risk. CO 2 levels are more related to ventilation efficiency and can help determine the need for air exchange, but in situations where oxygen levels are crucial, measuring oxygen levels is of primary importance. The oxygen level sensor continuously measures the oxygen content in the hypoxic space or a hypoxic compartment and transmits the data, for example, to a computer-controlled control unit that regulates the performance of the hypoxic system to achieve and maintain the desired air parameters in accordance with the training or therapy protocol.

[0066] According to a further or alternative embodiment, the system is equipped with a sensor that measures the oxygen content in the second compartment and is configured to shut down the hypoxic system when a measured oxygen content exceeds a predetermined threshold value. When the measured oxygen content exceeds a predetermined threshold value, it means that there is more oxygen present than desired for creating a hypoxic atmosphere. In response, the system is configured to automatically shut down the hypoxic system. This automatic shutdown ensures the safety of the users and prevents them from being exposed to unintended changes in atmospheric conditions that could lead to health risks. This provides reliable and accurate control over the hypoxic atmosphere in the second compartment, which is essential for the effectiveness and safety of the system.

[0067] According to a further or alternative embodiment, the system includes a user interface configured to set the oxygen content individually per space and / or per compartment, preferably each space is provided with at least one user interface. A user interface is optimal to enable athletes to adjust the oxygen content and thus the corresponding altitude simulation to their needs. It allows them to tailor the hypoxic environment to their individual training goals and physiological needs. Various types of user interfaces can be used, ranging from simple buttons and switches to advanced touchscreens with menus for detailed settings. It is important that the interface is intuitive and easy to understand for the athletes, so they can quickly and efficiently make the desired adjustments.

[0068] According to a further or alternative embodiment, the ventilation system is equipped with a flow controller and a Constant Air Volume (CAV) system to regulate an airflow from the ventilation system. The flow controller provides precise control over the amount of air flowing through the system, while the CAV system ensures constant airflow regardless of changes in external conditions. This results in more efficient use of energy, improved air quality, and flexibility in adjusting the ventilation to different environments.

[0069] According to a further or alternative embodiment, the system has a humidity and temperature control unit that regulates the humidity and temperature of the air within said spaces. By regulating the humidity and temperature of the air, the system can maintain a comfortable indoor climate suitable for the users of the spaces. This contributes to a more pleasant living or working environment. Maintaining the correct humidity and temperature levels contributes to better air quality in the spaces. This will help reduce allergens and promote healthier indoor air.

[0070] According to a further or alternative embodiment, the system is capable of simulating any mountain altitude, i.e., up to any height.

[0071] According to a further or alternative embodiment, the oxygen level formed in a hypoxic space and / or a hypoxic compartment using the current system is not particularly limited and depends on the purpose of the controlled atmosphere. In general, the present system is capable of maintaining an atmosphere with an oxygen content in the range of 5-40 vol. %, preferably 10-40 vol. %. More preferably, the system is capable of maintaining an oxygen content in the range of 13-30 vol%.

[0072] The desired oxygen levels that can be achieved using the present invention can be summarized as follows: At low oxygen levels, ranging from 5 to 13 volume percent (preferably between 7 and 13 volume percent), acclimatization to extreme altitudes is promoted, for example for mountaineers. These levels are also beneficial for intermittent exposure to promote athletic conditioning and for controlled medical exposure to diseases and ailments.

[0073] A reduced oxygen level, ranging from 13 to less than 21 volume percent, is used for athletic conditioning and mild acclimatization for sports activities.

[0074] Reduced and increased oxygen levels, preferably in combination, ranging from 13 to 40 volume percent (preferably between 13 and 30 volume percent), contribute to rejuvenation and vitality, sports rehabilitation and recovery, athletic conditioning, and medical improvement.

[0075] Enhanced oxygen levels, ranging from more than 21 to 40 volume percent, are used for sports rehabilitation and recovery, and medical therapy.

[0076] According to a further or alternative embodiment, the system is configured to bring the second compartment of the first space and a second space to an individually adjustable hypoxic atmosphere, preferably the system is adjustable to achieve a first oxygen content in the second compartment, which is representative of a first altitude, and a second oxygen content in the second space, which is representative of a second altitude, wherein said oxygen contents differ from each other. This configuration is important because it allows athletes to simulate and adapt specific altitude-related training environments to their individual needs. By setting the second compartment of the first space and a second space separately, the system will create different hypoxic atmospheres that are representative of different altitudes. This allows athletes to train under conditions similar to those at different altitudes, enabling them to benefit from the physiological adaptations associated with altitude training. The fact that the oxygen contents differ makes it possible to support a range of training intensities and goals, while also increasing the versatility and adaptability of the system.

[0077] In particular, it is provided to have a multitude of rooms divided into two compartments in a facility, e.g., in a hotel, so that a large number of athletes can simulate individually adjustable training conditions, without issues such as long-distance travel, difficult accessibility, poor weather conditions, and also always have access to other facilities, such as medical assistance, food supply, proximity to others (colleagues, trainers, family, etc.). By working with a large number of spaces, optimal use can be made of the hypoxic system, while each space is individually adjustable, greatly increasing flexibility.

[0078] According to a further or alternative embodiment, the system includes a multitude of rooms and one or more common spaces which are substantially airtight sealable from adjacent spaces, wherein at least a subset of the rooms correspond to the spaces of the system, and wherein the hypoxic system is further configured for the adjustable regulation of a hypoxic atmosphere in said one or more common spaces. This provides athletes with the opportunity to benefit from the advantages of altitude training without having to physically travel to higher altitude areas. The adjustable hypoxic atmosphere can be tailored to the individual needs and preferences of guests, allowing them to enjoy customized training programs designed to enhance their performance and well-being. Moreover, by also bringing common spaces into a hypoxic atmosphere, the length of stay in a hypoxic atmosphere is maximized and social interactions are promoted, thereby avoiding the feeling of isolation.

[0079] According to a most preferred embodiment, the invention relates to a system for creating individualized atmospheres within a sports training facility, the system comprising: a ventilation system suitable for creating a normoxic atmosphere; a hypoxic system suitable for creating a hypoxic atmosphere and for simulating different altitudes, the hypoxic system comprising a membrane nitrogen generator for generating an outgoing filtered airflow with a reduced relative oxygen content; and one or more enclosed spaces, wherein a first space is provided with at least two compartments that are substantially airtight separable from each other, wherein: a first compartment of the at least two compartments which includes sanitary facilities and at least one inlet and at least one outlet of the ventilation system configured for ventilating the first compartment under a normoxic atmosphere; a second compartment of the at least two compartments which includes a sleeping, resting, and / or sports facility, and at least one inlet and at least one outlet of the ventilation system configured for ventilating the second compartment under a normoxic atmosphere, and at least one inlet and at least one outlet of the hypoxic system configured for ventilating the second compartment under an adjustable hypoxic atmosphere, wherein the system is configured to, upon receiving instructions for generating a hypoxic atmosphere in one of the spaces, automatically close the inlet and outlet of the ventilation system in the second compartment of said space and open the inlet and outlet of the hypoxic system in the second compartment of said space and supply a filtered airflow from the membrane nitrogen generator into the second compartment.

[0080] According to a preferred embodiment, the system of the present invention will include further components for optimizing performance. Thus, in a preferred form, the system further includes a compressor for compressing air prior to introducing the air into the membrane nitrogen generator. The system may further include a filter for filtering air prior to introducing the air into the membrane nitrogen generator. As mentioned above, the system may also include a user interface for controlling the oxygen level of the atmosphere. Preferably, the oxygen level of each space and each compartment can be controlled. In some embodiments, the system further includes a climate controller, which is preferably capable of regulating the humidity of the atmosphere delivered to the subject.

[0081] In a second aspect, the invention relates to a use of a system according to the first aspect of the invention for creating individualized atmospheres in a hotel comprising a plurality of rooms and one or more common spaces which are substantially airtight sealable from adjacent spaces, wherein at least a subset of the rooms correspond to the spaces of the system, and wherein the hypoxic system is further configured for the adjustable regulation of a hypoxic atmosphere in said one or more common spaces.

[0082] In what follows, the invention is described by means of non-limiting examples or figures illustrating the invention, are not intended or to be interpreted as limiting the scope of the invention.DESCRIPTION OF THE DRAWINGS

[0083] Figures 1 and 2 each show a schematic top view of a system for creating individualized atmospheres within a sports training facility.

[0084] Figure 1 provides a detailed top view of two separate enclosed spaces (3) designed as hotel rooms. Each space (3) is divided into two clearly defined compartments (4,5).

[0085] A first individual space (3) consists of a first compartment (4) that can be equipped with sanitary facilities such as a shower and / or toilet. The second compartment (5) of this space (3) is intended as a sleeping, resting, and / or sports facility. The doors (11) are open, indicating that the space is currently not airtight and the hypoxic system (2) is therefore not in operation.

[0086] A second individual space (3) has a similar layout to the first individual space. The only difference here is that the doors (11) are closed, ensuring airtightness and suggesting that the hypoxic system (2) of the second compartment (5) is activated.

[0087] The hypoxic system (2) is designed to create a hypoxic atmosphere in the second compartment (5) of each space (3). This system includes a membrane nitrogen generator used to generate an outgoing filtered airflow with a reduced relative oxygen content. The inlets (9) and outlets (10) of the hypoxic system (2) open into the second compartment (5). When the hypoxic system (2) is activated, the inlet of the ventilation system (1) is closed off, and the filtered airflow from the membrane nitrogen generator is supplied to the second compartment (5), creating an adjustable hypoxic atmosphere.

[0088] The ventilation system (1) is responsible for maintaining a normoxic atmosphere in the spaces (3). This system consists of individual inlets and outlets connected to each compartment (4,5) in both spaces. Each individual inlet and outlet converge into a common air supply (6) or air exhaust (7). The ventilation system (1) ensures a continuous airflow and ventilation, maintaining a fresh and pleasant environment. Additionally, the ventilation system (1) is equipped with a valve system configured to regulate the air supply and exhaust in the spaces and / or compartments according to a user-adjustable atmosphere.

[0089] The valve system of the ventilation system is equipped with valves (8) placed between each inlet of the ventilation system and the common air supply (6). These valves (8) are suitable for individually activating or deactivating each inlet of the ventilation system, allowing the airflow to each compartment (4,5) to be regulated. This allows the user to individually adjust the atmospheric conditions in each space to their preferences and needs.

[0090] With these systems and valves, users can enjoy an individualized atmosphere within the sports training facility, where both normoxic and hypoxic conditions can be created and regulated for an optimal training experience.

[0091] Figure 2 builds on Figure 1 by showing the same two spaces but introduces a common space (12). The common space (12) will serve as a sports area, dining area, central meeting place, or the like for the users of the facility. This enhances the social experience and allows for a longer stay in a hypoxic atmosphere.

[0092] Like in the individual spaces (3), the common space (12) is equipped with a ventilation system (1) and a hypoxic system (2) to maintain the desired atmospheric conditions.

[0093] Finally, the figures illustrate with arrows how the airflow from both the ventilation system and the hypoxic system runs to and from the different compartments.

[0094] The reference numbers in the figures are: 1=ventilation system 2=hypoxic system 3=individual (enclosed) space 4=first compartment 5=second compartment 6=common air supply branching to individual inlets of the ventilation system to a space or compartment 7=common air exhaust branching to individual outlets of the ventilation system 8=valve 9=inlet hypoxic system 10=outlet hypoxic system 11=door 12=common space EXAMPLES

[0095] The invention will now be further explained on the basis of the following example, without however being limited to this.EXAMPLE 1

[0096] A cyclist stays for 14 days in a sports facility to optimize their training regime. This sports facility consists of 20 hotel rooms, a fitness room, a dining area, a relaxation area, shared sanitary facilities, a physiotherapy room, a meeting room, and other facilities.

[0097] Each hotel room consists of two compartments: a bathroom in the first compartment and a bedroom in the second compartment, separated by a door. In the second compartment of each hotel room, the fitness room, the dining area, and the relaxation area, a hypoxic atmosphere is created using a special hypoxic system. In contrast, the first compartment of each hotel room, the shared sanitary facilities, and the meeting room are provided with a normoxic atmosphere through a ventilation system.

[0098] The shared facilities are set at different altitudes: the fitness room at 1800 m equivalent altitude, the dining area at 2500 m equivalent altitude, and the relaxation area at 1500 m equivalent altitude.

[0099] Upon arrival in their hotel room, the cyclist sets the altitude of their hotel room to 5000 m equivalent altitude via a user interface. Once they close the door between the compartments and it is sealed airtight, the hypoxic system is activated. The hypoxic system draws the internal room air through an outlet to a membrane nitrogen generator and returns only the oxygen-poor gas mixture via the inlet. The membrane nitrogen generator thus receives compressed air, separates it over the membrane, and delivers the oxygen-poor gas mixture. This separation occurs due to a pressure difference, created by a compressor and / or vacuum pump. As a result of this setup, the oxygen-poor gas mixture is delivered in the second compartment, where the oxygen level of the air drops to match a simulated altitude of 5000 meters.

[0100] A major advantage of this is a gradual reduction in oxygen levels, allowing for better adaptation to the hypoxic condition and eliminating hypoxic shock. The user interface continuously informs a cyclist about the simulated altitude they reach during their stay in their enclosed hotel room. A major advantage of the invented system for this application is that it does not disturb a user and does not cause a "panic effect" that is genetically preset in humans when part of the oxygen in the air is replaced by carbon dioxide.

[0101] The cyclist primarily stays in the hypoxic spaces, maximizing their time in these environments. They notice a significant improvement in their performance after their stay in the facility.EXAMPLE 2

[0102] A group of cyclists stays in a sports facility. The cyclists adjust their individual hotel rooms to different equivalent altitudes, with the following settings: the first cyclist chooses an equivalent altitude of 2000 m; the second cyclist chooses an equivalent altitude of 3665 m; the third cyclist chooses an equivalent altitude of 4675 m; and the fourth cyclist chooses an equivalent altitude of 2950 m.

[0103] The cyclists decide to dine together every day in the common dining area, which is set to an equivalent altitude of 2500 m. This dining area has a volume of 400 m 3< , where the system could achieve an altitude difference of 2500 m equivalent altitude within 90 minutes.

[0104] When the cyclists break the airtight separations of their hotel rooms during their stay, the hypoxic system is turned off, resulting in energy savings as the system does not need to operate longer than necessary.

[0105] After their stay, the cyclists experience a significant improvement in their performance and have enjoyed a comfortable stay, partly thanks to the social contact.EXAMPLE 3

[0106] An athlete notices that they are starting to feel lightheaded during their stay in their hypoxic room. The sensor in their room detects that the oxygen level has exceeded a predetermined threshold and switches off the hypoxic system. The ventilation system is activated and the oxygen level in the room is normalized. This contributes to the optimal safety of the athlete.

[0107] The present invention is in no way limited to the embodiments described in the examples and / or figures shown. On the contrary, methods according to the present invention can be realized in many different ways without departing from the scope of the invention.
