Referring to fig. 1, in the preferred embodiment, an intelligent pressurization and oxygen supplementation system for enclosed buildings in high altitude areas comprises a monitoring unit 10 for monitoring air quality parameters inside the enclosed buildings in the high altitude areas, an air pressurization unit for performing pressurization and oxygen supplementation on the enclosed buildings in the high altitude areas, and a control unit 9 electrically connected with the monitoring unit 10 and the air pressurization unit, wherein the air pressurization unit comprises a first air pressurization mechanism and a second air pressurization mechanism, the first air pressurization mechanism comprises a blower 1 and a surge tank 2 connected with the blower, the second air pressurization mechanism comprises an air compressor 3 and an air storage tank 4 connected with the compressor, the surge tank 2 and the air storage tank 4 are both communicated with an air inlet of the enclosed buildings in the high altitude areas through corresponding pipelines, and the control unit 9 controls the air pressurization unit according to the parameters obtained by the monitoring unit 10, whether the first air pressurizing mechanism and the second air pressurizing mechanism operate or not is controlled.

The air storage tank 4 can be connected with a plurality ofThe table air compressor 3 to more quickly store the capacity in the air storage tank 4 to full. Since the pressure of the air blower 1 is unstable when the air blower directly pressurizes the enclosed building group in the high altitude area, the surge tank 2 is provided to buffer and stabilize the air. The capacity of the surge tank 2 is much smaller than the capacity of the air storage tank 4. After the air storage tank 4 stores the air compressed by the air compressor 3, the air compressor 3 does not need to work for a period of time because the capacity of the air storage tank is large, and the air storage tank 4 slowly performs pressurization and oxygen supplementation on the closed building group in the high-altitude area. Typically, the volume of the air reservoir 4 is greater than 20m³The volume of the pressure stabilizing tank 2 is more than 1m³。

Further, a filter 8 for filtering air is mounted on the pipeline at the outlet of the surge tank 2 and the air storage tank 4. The surge tank 2 and the air tank 4 may share one filter 8, or the surge tank 2 and the air tank 4 may be provided with one filter 8, respectively. In this embodiment, filter 8 filters the air through setting up, has improved the air quality.

When the first flow regulating device or the second flow regulating device fails, the second flow regulating device or the first flow regulating device can be started, namely, the flow regulating devices are redundant, and the standby valve is started when a problem occurs.

In addition, the first flow regulating device and the second flow regulating device can be operated manually, so that a user can close or open the valve manually under the condition of power failure.

Specifically, the monitoring unit 10 includes a temperature sensor, a humidity sensor, a pressure sensor, an oxygen concentration measuring instrument and a carbon dioxide concentration measuring instrument which are located in the high-altitude area enclosed building group, so as to monitor the temperature, the humidity, the pressure, the oxygen concentration and the carbon dioxide concentration in the high-altitude area enclosed building group respectively, and the parameters monitored by the monitoring unit 10 are sent to the control unit 9.

The stored energy of the standby power supply unit 11 should meet the basic requirements of lighting, water consumption, bathing and the like in a building group. The backup power supply unit 11 stores energy and can be electrically connected to the solar power generation device.

The air stored in the air storage tank 4 should meet the breathing requirement of the preset number of people (at least two preset numbers of people) in the closed building group in the high-altitude area within 24 hours.

Further, this airtight building crowd intelligence pressure boost oxygenating system in high altitude area still includes waste heat recovery equipment, and waste heat recovery equipment's first circulating water passageway is connected in order to retrieve the heat with air compressor 3's cooling water passageway, and waste heat recovery equipment's second circulating water passageway and domestic water equipment intercommunication are in order to provide hot water. Through setting up waste heat recovery equipment to retrieve the heat of air compressor, further reduce this pressure boost oxygenating system's energy consumption.

In addition, the blower 1 is also connected with a frequency converter, and the pressure stabilizing tank 2, the air storage tank 4 and pipelines thereof are all covered with heat insulation layers, so that energy consumption is saved.

The working process of the intelligent pressurizing and oxygenating system for the closed building group in the high-altitude area is as follows.

Acquiring a pressure value, an oxygen concentration value and a carbon dioxide concentration value in a closed building group in a current high-altitude area in real time through a monitoring unit 10;

when one of the three indexes of the pressure value, the oxygen concentration value and the carbon dioxide concentration value does not meet the preset condition, the control unit 9 controls the first air pressurizing mechanism and/or the second air pressurizing mechanism to perform pressurization and oxygen supplementation in the closed building group in the high altitude area;

when the three indexes of the pressure value, the oxygen concentration value and the carbon dioxide concentration value all meet preset conditions, the control unit 9 controls the first air pressurizing mechanism and the second air pressurizing mechanism to be closed with valves on communicating pipelines of air inlets of the closed building group in the high altitude area (at this time, a fresh air system in the closed building group in the high altitude area runs at low power to reduce energy consumption of the system).

According to the intelligent pressurization and oxygen supplementation system for the high-altitude area enclosed building group, the air pressurization unit comprises the first air pressurization mechanism and the second air pressurization mechanism, when one of the air pressurization mechanisms fails, the other air pressurization mechanism can still work normally, and normal pressurization and oxygen supplementation in the high-altitude area enclosed building group is guaranteed. In addition, the air storage tank 4 can store energy (the air compressor 3 is utilized to compress air in advance, and the air in the air storage tank 4 is slowly released in the case of power failure), and can be used as an air source to perform oxygen supplementation and pressurization on a high-altitude area closed building group in an emergency (in the case of power failure). The intelligent pressurizing and oxygenating system for the enclosed building group in the high-altitude area has the advantages of reliable work and easy realization.

According to the pressurizing oxygen supplementing method provided by the embodiment, the air quality in the closed building group in the high-altitude area is ensured by monitoring three parameters of the pressure value, the oxygen concentration value and the carbon dioxide concentration value.

In addition, when the electric energy stored in the solar power generation device is larger than the preset electric energy or the electricity price is lower than the preset electricity price, the air compressor 3 is controlled to supplement pressure to the air storage tank 4, waste heat recovery is carried out through waste heat recovery equipment in the working process of the air compressor 3, and the recovered heat provides domestic hot water or heating requirements for building groups.
