To a controlled environment for long-term, sustained, effective control, you must also have control over the entire system, that is, in addition to the Interior control, but also on regional and on control of air conditioning systems. As long as the system has a hidden danger of microbial contamination, even ten thousand times cannot be guaranteed and qualified, or eliminate the pollution in the event. So only eliminate system of microbiological pollution hazards, or of any possible risks in order to guarantee that fundamentally eradicate microbial contamination.

Air conditioning system, usually occurring microorganism contamination exists of the following three-part relationship chain: there is an accumulation of microorganisms; the propagating microorganisms is thrown; the accumulation and spread of microorganisms from the susceptible population of transmission.

To a controlled environment to implement long-term, sustained, effective control, you should use the following countermeasures: prevent microbial into air conditioning ventilation system; if the entry does not allow reproduction of microorganisms in the system; the event propagation, removal of micro-organisms through the system of transmission.

Prevent micro-organisms entering the units or biological purification system, is an important principle that is total control of a starting point. And air filter, just to prevent micro-organisms entering the system's most effective measures. Enter the system usually two mouths, new air inlet and outlet at the back. We usually pay attention to access to outdoor air quality, attention to a new outlet of primary efficiency filters, but as mentioned earlier, there is almost no bacteria in the fresh air. Therefore, we should pay more attention to return to the role of air filters.

Illustration for the architectural design of the specification in general hospitals, in the hospital back outlet, air conditioning system should set low resistance Middle effect air strainer, intended to prevent the bacteria enter the system.

Do not let bacteria multiply in the system, not by disinfection kills microorganisms, but by not allowing system dust, water, do not use easy nourishing bacteria mouldy material measures to eradicate microbial survival conditions.

And, on the regional and the system adopts comprehensive measures to spread down the system, for example, in the system settings for air filters, each functional area of an independent partition, using independent system, and that the air conditioning Division can mutually closed to avoid downtime that occurs when air ways cross infection. In a room with cleanliness requirements, serious pollution in the room, it should also be taken as a single system.

Visible, bio clean technology on controlled environment implemented a long-term, sustained, effective control.

Indoor microbial environment control, should pay attention to reduce microbial pollution load

We should clearly understand that air conditioning is a dissipation of environment control, control of limited capacity. HVAC there on indoor environment control enabling role, but also have many negative impacts. Reduce the load, reducing the capacity of the HVAC system, has always been our important task. This not only reduces investment and lower operating costs, and more to create a good interior environment is an important way of thinking.

Do not exaggerate the role of conditioning, do some great work of HVAC, especially for biological purification, even more so.

For example, for thermal environment control, often focus on improving support structure, reduce solar radiation and other building measures, to reduce the thermal load. If this is all glass building, will be part of the load in HVAC, even if they cannot reach the required temperature and humidity control parameters, it is difficult to guarantee a comfortable and healthy indoor personnel.

Another example, industrial ventilation, also has focused on improving process, isolation or control pollution, and other measures to reduce the pollution load to a shorter time, closer to exclude pollution, rather than after, such as pollution dispersion with a greater amount of wind to fully ventilated, this will not only effect worse, also causes indoor air speed too high, too much noise and energy consumption.

Therefore, for indoor microbial environment control, should pay attention to reduce biological pollution load, eliminating or reducing transmission possibilities. This effectively lowers the air conditioning control air transmission requirements and scope, is essential.
