Problems solved by technology

Although this technology can achieve the above purpose, it ignores the reality that there are about 70% nitrogen in the air. After removing carbon dioxide and nitrogen in the indoor air, the negative pressure generated by the drop in the indoor air pressure will inevitably lead to the entry of outdoor air. Several consequences: if the outdoor air is polluted, it will cause indoor air pollution; if it is used in conjunction with an air conditioner, it will discharge cold air and introduce hot air in summer, reducing the cooling effect; in winter, it will discharge heating air and introduce cold air to reduce heating effect, both will cause a certain amount of energy loss

Embodiment Construction

[0018] like figure 1 As shown, the device of the present invention is composed of indoor and outdoor air suction selection pipelines, air delivery pipelines, carbon dioxide pressure swing adsorption pipelines connected in parallel, carbon dioxide and nitrogen adsorption pipelines, and return pipelines. connected in turn. The air suction selection pipeline is composed of a two-position three-way valve 3 and its two inlets connected to the air inlet pipe 1 connected to the room and the air inlet pipe 2 connected to the outdoor air. The air delivery pipeline is composed of a micro air pump 4 and a three-position three-way valve. Valve 5 is formed, and the inlet of miniature air pump 4 is connected with the outlet of two-position three-way valve 3 through pipeline, and its two outlets are connected with carbon dioxide adsorption chamber 10 and nitrogen and carbon dioxide adsorption chamber 8 through pipeline respectively, and carbon dioxide adsorption chamber 10 is connected with ...

Abstract

The present invention relates to method and device for eliminating indoor CO2 and increasing O2. The method includes the following steps: setting lowest indoor O2 concentration value and highest indoor CO2 concentration value; detecting indoor air to monitor the indoor O2 concentration and highest indoor CO2 concentration; sucking air from outdoor via pressure varying adsorption process to eliminate CO2 and N2 from indoor in case of lower indoor O2 concentration; and pumping indoor air via pressure varying adsorption process to eliminate CO2 before returning the air into indoor in case of higher indoor CO2 concentration. The device consists of indoor and outdoor air suction selecting pipeline, air conveying pipeline, parallel CO2 pressure varying adsorption pipeline, CO2 and N2 adsorption pipeline and return pipeline connected successively.

Description

technical field [0001] The invention relates to a method for improving indoor air quality, in particular to a method for removing carbon dioxide and increasing oxygen indoors, and also relates to a device for realizing the method. Background technique [0002] Modern medicine has proved that low oxygen concentration and high carbon dioxide concentration in indoor air will bring a series of health problems. Low oxygen concentration (for example, less than 17-19%), long-term hypoxia in the human body will cause chest tightness, shortness of breath, dizziness, headaches, etc.; high carbon dioxide concentration (for example, more than 8%), people will feel fatigued and dull , shortness of breath, roughness of breath, wheezing and other symptoms. Inhaling more fresh oxygen can keep a clear mind, strong memory, smooth blood circulation, prevent arteriosclerosis, prevent dementia, prevent cancer and other functions. Therefore, it is necessary to improve the indoor air environment...
