Definitions

  • the invention relates to a method of supplying breathing air with a lower oxygen content than normal breathing air to a basically gas-tight room, in which the pressure is maintained at that of the surrounding atmosphere.
  • the invention further relates to an installation for supplying breathing air with a lower oxygen content than normal breathing air to a basically gas-tight room, in which the pressure is maintained at that of the surrounding atmosphere.
  • the only known altitude training facility based on normal atmospheric pressure is a Finnish invention.
  • this concept is based on the continuous circulation of a mixture of oxygen and nitrogen through the room, the supply being controlled so as to maintain the desired oxygen content at all times.
  • a very high gas flow is required at all times to maintain a uniform gas quality throughout the room and to remove carbon dioxide (CO2) exhaled during the training activities in which the occupants of the room are engaged.
  • CO2 carbon dioxide
  • the purpose of the invention is to provide a method and an installation which, in a simple and inexpensive manner, makes it possible to control the oxygen level in a closed room in which normal air pressure is maintained.
  • a further purpose of the invention is to provide a method and an installation such that it is unnecessary to supply gases other than ordinary air.
  • This method is, in accordance with the invention, characterised in that, on the one hand, activities are carried on which, considered in isolation, tend to lower the oxygen content in the closed room to a non-breathable level, and that, on the other hand, the effects of these activities are counterbalanced by replacing the breathing air from the closed room by ordinary air from the outside atmosphere, enabling a predetermined oxygen content to be maintained.
  • To maintain the quality of the breathing air it is necessary to remove CO2 and other undesirable gases produced by the breathing activities of the occupants of the altitude room. This can be achieved by filtering the air and/or by ensuring that the activities in question require frequent changing of the air in the room.
  • the oxygen level may be reduced to the predetermined level by breathing.
  • this is likely to be time-consuming in large rooms, even if the level of physical activity is high. It may be desired, especially during initial operation, to perform 'activities' which will reduce the oxygen level in the room rapidly. Catalytic combustion of oxygen may be relevant in this context.
  • Another alternative may be to use a 'nitrogen generator', which will enable considerable quantities of oxygen to removed quickly from the room.
  • Mechanical devices of this type should preferably be based on a special membrane technology which enables air to be separated into an oxygen-rich and a nitrogen-rich component (up to approx. 99% nitrogen).
  • the nitrogen generator is used to separate air from the altitude room, the nitrogen-rich component being returned to the room and the oxygen-rich component being discharged directly to the surrounding atmosphere.
  • the oxygen-rich component will also include any CO2 in the separated air.
  • Nitrogen generators are commonly used, for example, to establish suitable storage conditions for fruit and vegetables.
  • the nitrogen generator is adjusted so that the storage room is supplied with air with a constant, low oxygen content. This is achieved by supplying air consisting of the nitrogen-rich component mixed with some of the oxygen- rich component. In this method, therefore, all of the air supplied to the room is supplied by the nitrogen generator.
  • a nitrogen generator is a relatively energy-intensive device, resulting from the fact that the air pressure must be raised to an estimated 7-10 bar to ensure that the separation process is sufficiently effective.
  • a substantial energy saving relative to the change of air performed in the room is achieved. This is due to the fact that the nitrogen generator is operated only for the purpose of removing oxygen from the altitude room, enabling the oxygen level in the room to be lowered to the desired value at optimum energy consumption.
  • a relatively significant air change can be achieved at moderate energy consumption during normal operation of the room, due to the fact that most of the change is performed by supplying 'fresh' air under pressure directly from the surrounding atmosphere.
  • the 'altitude room' 1 shown in the figure is enclosed by impervious walls 2, and by a ceiling and floor, such that the room is effectively gas-tight.
  • the walls incorporate a lock 3 to minimise gas leakage when people enter or leave the room.
  • the installation is provided with a first piping system 4, with a number of air intakes 5 in the room 1 and an outlet 6 to remove breathing air from the room with the aid of a fan unit 7 equipped with a fan 8.
  • the installation is further provided with a second piping system 9, with a number of air outlets 10 in the room 1 and an external intake
  • the breathing air outlet 6 and the air intake 11 are provided respectively with non ⁇ return valves 12 and 13, whose purpose is to prevent unintended air leakage into the room.
  • both the air intakes 5 and the air outlets 10 are distributed around the room to achieve a largely uniform air distribution in the room.
  • the installation further includes an oxygen control system 14 consisting of a number of oxygen sensors which control the fan unit 7 through an electronic control circuit 15, in such manner that the fan 8 is started when the oxygen level falls below a preset value.
  • the oxygen sensors are distributed throughout the room 1 , they are represented on the figure by the block 14.
  • the fan 8 is preferably provided with steplessly variable speed control and is arranged to run at increasing speed if the oxygen level continues to fall below the preset value.
  • the oxygen level is stabilised efficiently by adjusting die supply of air with a normal oxygen content as required to maintain the desired value.
  • the installation also incorporates a filtering unit 16 for removing CO2 and other undesirable gases from the breathing air in the room.
  • the unit consists of a filter housing 17 containing a CO2 absorber 18 and a fan 19, which maintains a continuous flow of a relatively high volume of air through the CO2 absorber.
  • the latter consists of suitable, commercially available material, such as granulated lime.
  • the filtering unit 16 also incorporates a carbon filter to remove the other undesirable gases from the breathing air.
  • the installation also includes a mechanical unit 20 to remove oxygen from the air in the altitude room.
  • This unit is normally installed outside the room to exclude noise, heat emission etc.
  • the other climatic conditions in the altitude room can be controlled simply with the aid of suitable, commercially available equipment.
  • the air temperature and relative humidity can be controlled within relatively wide limits by including a dehumidifier using silica gel.

Abstract

Procédé et installation servant à alimenter une pièce fermée (1) en air respirable, dont la teneur en oxygène est inférieure à la normale et dans lequel on maintient une pression égale à celle de l'atmosphère ambiante. Dans le mode de réalisation de l'invention, on exerce des activités, qui, si on considère l'isolation de la pièce fermée, tendent à abaisser la teneur en oxygène à un niveau non respirable, tandis qu'on utilise un système de commande d'oxygène (14) et un ensemble de ventilation (7) fonctionnant conjointement afin de remplacer l'air de l'air respirable de la pièce par de l'air provenant de l'atmosphère environnante, de manière à stabiliser le niveau d'oxygène dans la pièce à un niveau prédéterminé. On supprime, à l'aide d'un ensemble de filtration (16), d'autres gaz, particulièrement le CO2, qui peuvent exercer un effet négatif sur la qualité de l'air respirable de la pièce (1).
