Description

Intelligent purification antibacterial air-treatment unit

Technical field

The present invention relates to a kind of air-treatment unit, particularly to a kind of antibacterial air processing machine of intelligent purification Group.

Background technology

Architecture indoor Particulate Pollution is the key factor affecting indoor air quality, has the most become complete The focus of world attention.Aerodynamic diameter is referred to as fine particle less than the granule (PM2.5) of 2.5 μm, Pulmonary deposition can be arrived by upper lower respiratory tract and bronchus, even with alveolar, enter blood of human body, In addition heavy metal, acidic oxide, organic pollution, microorganism etc. often it are enriched on particulate matter, this Particulate Pollution and combined pollution thereof are one of pollutant maximum to harm.Research finds that PM2.5 puts down The most often increase by 10 μ g/m3, general mortality rate increases by 1.5%, and WHO estimates that the whole world is died from indoor every year and can be sucked The number of Particulate Pollution is up to 2,800,000.The research worker of the mechanisms such as Brigham Young Univ. of the U.S. calculates and draws, 1m3Fine particle in air often reduces by 10 μ g, and the average life expectancy of the people can extend about 7 months.

It is one multi-functional section of combination that regular air processes unit, as it is shown in figure 1, described air-treatment unit Including be arranged in order: wind inlet section 1, first medium efficiency filtration section (containing low efficient filter 2, medium effeciency filter 4), Table is cold/bringing-up section 5, reheating section 6(be optional), humidifier section 7(optional), fan section 8, flow equalization section 9 with Wind outlet section 10, all connects with changeover portion 3 between each functional section, and reheating section 6 therein, humidifier section 7 can roots Require that the height of class selects to arrange or be not provided with according to indoor comfort, it is however generally that needs when top grade requires Arranging, general comfortableness is often not provided with when requiring.

Owing to the degree of establishment of regular air datatron set filter is usually no more than medium effeciency filter, and middle effect Filter is relatively low to the filter efficiency of PM2.5 fine particle, therefore uses this structure, in outdoor haze sky Under gas or when indoor dust-producing amount is bigger, the operation of air conditioning system is often it is difficult to ensure that IAQ (indoor air quality).As needed Ensure IAQ (indoor air quality), then should set up the higher high-medium efficient of efficiency in air-treatment unit even sub-efficiently Air filter, but during due to filter clogging effect height, resistance is the biggest, can cause air-conditioning draught fan energy consumption Increase, in civil buildings regular air processes unit, be therefore often rarely employed high-medium efficient even sub-the most empty Air filter, haze weather is not to have everyday after all, and the concentration of room air PM2.5 is also in most cases Requirement can be met.

Additionally, air conditioning system especially air-treatment unit casing is a polluter because inside it by from The water flowed down on surface cooler (or vaporizer), and be the most often moist on the most each section of wall, easily grow Endophytic bacteria.So not having the air-treatment unit of bacteria resistance function is not very health, aseptic air conditioning system.

In view of this, for solving some deficiency in existing air conditioning system technology, the design people is based on relevant neck The research and development in territory, and through constantly test and improvement, and then have the generation of the present invention.

Summary of the invention
