Description
Technical field
The present invention relates to a kind of air-treatment unit, particularly the antibacterial air-treatment unit of a kind of intelligent purification.
Background technology
Architecture indoor Particulate Pollution is a key factor that affects indoor air quality, has become the focus that the whole world is paid close attention at present.The particle (PM2.5) that aerodynamic diameter is less than 2.5 μ m is called fine particle, can pass through upper lower respiratory tract and bronchus, arrive pulmonary deposition, even pass through alveolar, enter blood of human body, in addition on particle often enrichment heavy metal, acidic oxide, organic pollution, microorganism etc., this Particulate Pollution and combined pollution thereof are to one of pollutant of harm maximum.Average every increase by the 10 μ g/m of PM2.5 are found in research
3, general mortality rate increases by 1.5%, WHO and estimates that the number of dying from every year indoor pellet pollution in the whole world is up to 2,800,000.The researcher of the mechanisms such as U.S. Brigham Young Univ. calculates and draws, 1m
3the every minimizing 10 μ g of airborne fine particle, the average life expectancy of the people can extend approximately 7 months.
Conventional air-treatment unit is one multi-functional section of combination, as shown in Figure 1, described air-treatment unit comprises and being arranged in order: wind inlet section 1, fillter section is imitated (containing low efficient filter 2 in junior middle school, medium effeciency filter 4), show cold/bringing-up section 5, hot arc 6(is optional again), humidifier section 7(is optional), fan section 8, flow equalization section 9 and wind outlet section 10, between each functional section, all with changeover portion 3, connect, hot arc again 6 wherein, humidifier section 7 can require the height of class to select arrange or do not arrange according to indoor comfort, when generally speaking top grade requires, need to arrange, general comfortableness does not often arrange while requiring.
Because the degree of establishment of conventional air processing machine set filter is generally no more than medium effeciency filter, and medium effeciency filter is lower to the filter efficiency of PM2.5 fine particle, therefore adopt this structure, under outdoor haze weather or when indoor dust-producing amount is larger, the operation of air-conditioning system is often difficult to guarantee IAQ.As need guarantee IAQ, should in air-treatment unit, set up even inferior high-efficient air filter of high-medium efficient that efficiency is higher, but because filter clogging effect is when high, resistance is often larger, can cause the increase of air-conditioning draught fan energy consumption, therefore in the conventional air-treatment unit of civil buildings, often seldom use even inferior high-efficient air filter of high-medium efficient, haze weather is not to have everyday after all, and in most of situation, the concentration of room air PM2.5 still can meet the demands.
In addition, air-conditioning system especially air-treatment unit casing is pollution sources, because its inside is by the water flowing down from surface cooler (or evaporimeter), and is often also moist on each section of wall thereafter, easily breed bacteria.So there is no the air-treatment unit of bacteria resistance function is not very air-conditioning system health, aseptic.
In view of this, for solving some deficiency in existing air-conditioning system technology, the research and development of the design people based on association area, and through constantly test and improvement, and then have generation of the present invention.
