Solve the pollution problem of the central air conditioning ventilation system of the point?
For most people, the central air conditioning is not strange.
After 92 air-conditioning began to spread in our country, with people living standard rise, the rise of industry, technology, product constantly improve, central air conditioning nobody don't know.
Is understood to be in China more than 500 central air conditioning using family and each unit, increasing at the rate of 10% a year.
Most central air-conditioning ventilation system has never been cleaned, but we all know that use will change with time, the central air-conditioning ventilation system internal back to precipitate dust, bacteria, and so on pollution problems!
Then we will go to solve the problem, some people think, solve the pollution problem of the central air conditioning ventilation system of meaning?
Small make up together with you and see what is the meaning?
03 (severe acute respiratory syndrome (SARS)
People aren't strange!
The SARS outbreak in the spring of that year caused serious threat to human health, due to the SARS virus is very small, about 40 ~ 100 nm, it need to rely on as a carrier for transmission can be suspended particles in the air when the SARS virus spread and popular one of the main reason is the central air conditioning ventilation system.
The SARS virus is confirmed through the central air-conditioning duct dust accumulation of a large number of impurities in the system.
It is understood that due to the dangers of influenza, SARS in China in August 2003, the ministry of health issued 'central air-conditioning ventilation systems in public places health standards', then take effect in March 2006 the 'measures for the central air conditioning ventilation system health management in public places and the central air conditioning ventilation system cleaning regulations in public places in the rules and regulations of the central air-conditioning ventilation systems in public places (
Hereinafter referred to as the central air conditioning ventilation system)
The sanitary requirements and test methods.
And specification applies to the use of central air conditioning ventilation system in public places, central air conditioning ventilation system can be reference to other places.
These policies and regulations tell us solve the pollution problem of the central air-conditioning ventilation system is not only meaningful, but also brought to the attention of the CPC Central Committee leaders at all levels.
Then small make up take you learn together to solve the central air conditioning ventilation system of the significance of the problem of pollution?
The central air conditioning system has become a modern business office building, hospital, food factory of air, such as metabolism, masters from main part of the life breath.
It is understood that in the United States and Europe, according to a survey of the central air conditioning ventilation system due to the long run, cleaning and maintenance is not in place, the indoor air pollution mainly comes from the air conditioning and ventilation system.
Which accounts for 42% to 53% after using micro mirror analysis of ventilation system in main pollutant for particles and microorganisms.
The key is that if the dust of adhesion with the microorganisms such as bacteria, fungi, yeast, so it is easy to make people suffer from allergy or respiratory system diseases and related diseases.
The ventilation system of central air conditioning pollution is use for a long time or shelve accumulated health dead Angle, cleaning the unit area is very limited.
Then these duct corner is not clean, to provides a breeding ground for breeding of harmful substances, and the safe environment, they will be as duct widespread indoors, extending in all directions in the air conditioning internal cause air pollution.
Ventilating and air conditioning system and building caused by the human body health hazard and disease can reach dozens, or even more.
Know now that solve the pollution problem of the central air-conditioning ventilation system what is the meaning?
Hope like 03 SARS, 09 influenza a (H1N1) virus is not in the earth, also hope that more friends can join to solve the pollution problem of the central air-conditioning ventilation system in the army together can do contribution to the health of the us and family.
Peace to health with you and your family happiness.
