Supercharging and oxygen supplementing system for closed living space in high-altitude area

Abstract

The invention discloses a supercharging and oxygen supplementing system for a closed living space in a high-altitude area. The system comprises a supercharging module, a fresh air module and a controlmodule; the supercharging module comprises an air compressor or an air blower, an air storage pressure stabilization tank, a refrigerated air dryer and air filters; the fresh air module comprises twist outlets, a static pressure box, an air supply pipe, an air inlet pipe, a pressure regulating valve and an exhaust valve, wherein the twist outlets are distributed on the surface layer of an indoorfloor, the static pressure box is formed by an empty space on the lower portion of the floor and a building structure, the air supply pipe is located in the static pressure box and is provided with air supply holes in a distributed mode, the air inlet pipe introduces fresh air into the air supply pipe, the pressure regulating valve is arranged on the air inlet pipe, and the exhaust valve is used for indoor air exhaust and pressure reduction indoors; and the control module comprises a sensor and a controller, wherein the sensor is used for acquiring the indoor air pressure and the oxygen concentration, and the controller can control the supercharging module and the fresh air module to adjust the indoor air pressure and the oxygen concentration according to the collected data. The system hasthe advantages that a suitable living environment can be provided for the closed living space in the high-altitude area, and therefore the comfort of a human body is guaranteed, and the initial investment and operation cost are saved.

Description

technical field [0001] The invention belongs to the field of architectural design and construction in high-altitude areas, and in particular relates to a pressurized and oxygen-supplementing system for closed living spaces in high-altitude areas. Background technique [0002] High-altitude areas have low air pressure and low oxygen content. When people, especially those in low-altitude areas, live in high-altitude areas for short-term or long-term and exercise to a certain extent, they will generally suffer from high-altitude hypoxia and are prone to various altitude sicknesses. Seriously endanger physical and mental health and work efficiency. In order to solve this problem, local pressurization and oxygen supplementation are required. At present, the most widely used local pressurized oxygen supply is the hyperbaric oxygen chamber. The working method of the hyperbaric oxygen chamber is to compress the air into the high-pressure gas storage tank through the volumetric compr...

Problems solved by technology

Existing hyperbaric oxygen chambers adopt volumetric air compression technology for pressurization. Volumetric compression technology is efficient, easy to store pressure, and has a large pressurization range (7-15 atm). At the same time, the equipment is complicated, energy consumption is high, and safety hazards are great.

[0003] The range of pressurization required for plateau hypoxia treatment is not large. In theory, an increase of more than 0.3atm can solve the plateau hypoxia at an altitude of 3000 meters. The use of hyperbaric oxygen chambers can far meet the requirements of pressurization, but there are two Problem: 1) The structure of the hyperbaric oxygen chamber is very complicated, and it can increase 7-15 atm to treat plateau hypoxia. If it is used in the living space, the cost will increase significantly; 2) The hyperbaric oxygen chamber belongs to intermittent work delivery The wind is uneven, the indoor air circulation is poor, and the air delivered is not clean, which cannot provide a suitable environment for the living space
