Intelligent purifying and bacterium resisting air processing machine set

Abstract

The invention provides an intelligent purifying and bacterium resisting air processing machine set. The intelligent purifying and bacterium resisting air processing machine set comprises a high-medium or sub-high efficiency air filtering section. The high-medium or sub-high efficiency air filtering section is in parallel connection between an air inlet section and a surface cooling / heating section of the machine set. A first-mode starting and stopping valve is arranged between a primary-medium efficiency filtering section and the surface cooling / heating section of the machine set, a second-mode starting and stopping valve is arranged between the high-medium or sub-high efficiency air filtering section and the surface cooling / heating section, and either the first-mode starting and stopping valve or the second-mode starting and stopping valve is opened. In this way, the working modes can be automatically switched according to the concentration of PM2.5 of indoor air and the concentration of PM2.5 of outdoor air, the concentration of PM2.5 pollutants of the indoor air is effectively controlled on the premise that energy resources are saved, and accordingly a clean indoor environment is built.

Description

technical field [0001] The invention relates to an air treatment unit, in particular to an intelligent purification and antibacterial air treatment unit. Background technique [0002] Indoor particulate matter pollution in buildings is an important factor affecting indoor air quality, and has become the focus of attention all over the world. Particles with an aerodynamic diameter of less than 2.5 μm (PM2.5) are called fine particles, which can pass through the upper and lower respiratory tracts and bronchi, reach the lungs for deposition, and even enter the human blood through the alveoli. In addition, the particles are often enriched with heavy metals, acid oxidation Such particulate pollution and its compound pollution are one of the most harmful pollutants to the human body. The study found that every 10μg / m increase in PM2.5 on average 3 , the total mortality rate increased by 1.5%, and WHO estimates that the number of people who die from indoor inhalable particulate p...

Problems solved by technology

[0004] Since the filter setting level of conventional air handling units generally does not exceed the medium-efficiency filter, and the filter efficiency of medium-efficiency filters for PM2. When the amount of dust is large, the operation of the air conditioning system is often difficult to ensure the indoor air quality

If it is necessary to ensure indoor air quality, a high-efficiency high-efficiency or even sub-high-efficiency air filter should be added to the air handling unit. However, when the filter efficiency is high, the resistance is often large, which will increase the energy consumption of the air-conditioning fan. Therefore, high-efficiency or even sub-high-efficiency air filters are rarely used in conventional air handling units in civil buildings. After all, haze weather does not happen every day, and the concentration of indoor air PM2.5 can still meet the requirements in most cases.

[0005] In addition, the air conditioning system, especially the air handling unit box, is a source of pollution, because the water flowing down from the surface cooler (or evaporator) inside it, and the walls behind it are often wet, which is easy to breed bacteria

Therefore, the air handling unit without antibacterial function is not considered a hygienic and sterile air conditioning system.
