An air component automatic adjustment device and its control method

Abstract

The invention relates to the technical field of air conditioning and discloses a novel automatic air composition conditioning device and a control method thereof. The novel automatic air composition conditioning device comprises an air supplementing device, a pressurizing device, a washing device, an adsorption device, an ultrasonic wave atomizing device, an ultraviolet light sterilization device and an air-conditioning constant-temperature device which are arranged sequentially and are communicated mutually. The adsorption device comprises at least two adsorption tanks, activated carbon, kiselgel A, molecular sieves, a first program control valve blank, a second program control valve blank, a third program control valve blank and a fourth program control valve blank, wherein the lower portions, the middle portions and the upper portions of the adsorption tanks are filled with the activated carbon, the kiselgel A and the molecular sieves respectively, the first program control valve blank is communicated with the upper portions of the adsorption tanks, and the second program control valve blank, the third program control valve blank and the fourth program control valve blank are communicated with the lower portions of the adsorption tanks. The novel automatic air composition conditioning device and the control method thereof have the advantage that indexes such as temperature, humidity, impurity (for example, PM2.5) concentration, harmful component (for example, formaldehyde) concentration, oxygen content, CO2 content, ventilation volume and ventilation frequency can be conditioned automatically and continuously.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, and more specifically relates to an automatic air component adjustment device and a control method thereof. Background technique [0002] With the development of urbanization in our country, especially the rapid increase of urban population, the rapid development of industry and the geometric growth of automobile exhaust emissions, urban pollution has become quite serious. in the environment. The concentration of total suspended particulate matter in the air of cities across the country generally exceeds the standard, some cities suffer from serious carbon dioxide pollution, and the total amount of air pollutant emissions remains high. Now, the country's annual emissions of sulfur dioxide are as high as 11.14 million tons, 11.59 million tons of smoke and dust, and 11.75 million tons of industrial dust. Air pollution is very serious. The quality of the air environment in most ci...

AI Technical Summary

Problems solved by technology

[0007] In summary, it can be seen that the prior art has the following disadvantages: 1. The prior art cannot realize all indicators in the air including temperature, humidity, particle (such as PM2.5) concentration, harmful component (such as formaldehyde) concentration, oxygen content and CO2 content, etc., but only adjust one or several of them; 2. The existing technology cannot realize automatic adjustment of all indicators in the air, which are all manual or semi-automatic adjustments; 3. The existing external The investment cost of circulating air purification device is relatively high, and the purification effect is not good; 4. The existing internal circulation air purification device adopts indoor gas circulation purification (including the portable purifier of adsorption-desorption principle), and the device is placed indoors. It communicates with the outside air, so fresh air cannot be replenished in a timely manner. The content of CO2 in the air is generally too high, and the replacement capacity is limited; in addition, because the purifier is low in cost, it is usually portable, with single function and limited processing capacity; internal circulation air purification device The structure of the medium filter focuses on filtering out impurities and harmful substances, without oxygen enrichment and sterilization functions, and the filter needs to be cleaned manually and cannot be automatically regenerated, and the filtering function is quite limited; the main function of the release structure is to sterilize and deodorize through ionization, but it does not have Filtration of micro particles (such as PM2.5, etc.) and oxygen-enriching functions; the electric field structure relies on ozone for sterilization and deodorization, but ozone itself is a polluting gas; adsorption-desorption portable purifiers focus on oxygen enrichment, without sterilization and humidification and constant temperature function; other structures and functions are single, and the purification effect is limited
