Description

Technical Field

[0001] The invention relates to a ventilation system, in particular to a ventilation system for a closed living space. Background Art

[0002] The air pressure in high altitude areas is low and the oxygen content is low. When people, especially those in low altitude areas, live in high altitude areas for a short or long time and exercise to a certain extent, they generally suffer from plateau hypoxia, which is prone to various altitude diseases, seriously endangering physical and mental health and work efficiency. In order to solve this problem, local pressurization oxygen supplementation is needed. At present, the most widely used local pressurization oxygen supplementation is the hyperbaric oxygen chamber. The working mode of the hyperbaric oxygen chamber is to compress the air into the high-pressure gas storage tank through a positive displacement compressor, and then release the compressed air in the high-pressure gas storage tank into the hyperbaric oxygen chamber through a control device, thereby increasing the purpose of the air pressure in the cabin. Existing hyperbaric oxygen chambers all use positive displacement air compression technology for pressurization. The positive displacement compression technology is efficient, the pressure is easy to store, and the pressurization range is large (7-15 atm). At the same time, the equipment is complex, the energy consumption is high, and the safety hazard is large.

[0003] The pressurization range required for plateau hypoxia treatment is not large. Theoretically, an increase of more than 0.3atm can solve the plateau hypoxia at an altitude of 3,000 meters. The use of hyperbaric oxygen chambers can far meet the pressurization requirements, but there are still defects: the structure of the hyperbaric oxygen chamber is very complicated. If it is used for a long time in a closed living space, the cost will increase significantly. The hyperbaric oxygen chamber is an intermittent working chamber with uneven air supply, poor indoor air circulation, and the delivered air is not clean, which cannot provide a suitable environment for the living space.
