The airport is the guest's first impression of the city, the master at the first place. Reasonably choose the local airport air conditioning system, then the best configuration, the airport air conditioning system show that the strength of the master and the level of air conditioning designer.

In the air conditioning system in developed countries large airport, air filter common configuration is:

    G4～F6 The pre-filter → Activated carbon filter → F7 At the end of the filter

    F7 The filter The most common filter in public places.After F7 filter, air dust concentration can reach the level of the scenic spots. Unless you more money, there is no need to increase the filtration efficiency further to F8.Specified in the national standard, lounge pm10 concentration limit of 0.15 mg/m3, it is a minimum requirement in terms of health, a concentration equivalent to level 2 levels of atmospheric pollution, outdoor air also is lower than the concentration at the airport.Air conditioning design, airport consider is class,and not just for the health. In addition, if the demand terminal internal decoration such as new for many years, when the design must consider to choose F7 filter.

    Airports have petrol, although most of the guests will not complain, but master, still need to be explored. Therefore, eliminate the odor of activated carbon filter become a standard configuration in the airport air conditioning in the developed countries.There's no technology, just grade of the theory. If the filter is a luxury in air conditioning, activated carbon filter is the best, it's test the strength of the investors and operators at the airport.

    The role of the filter is to protect the air conditioning system, and extend the service life of filter at the end.A prefiltering is insufficient, can set two way; Request the pre-filter service life is long, can choose large filtering area of the filter.As long as the filtration efficiency is reasonable, the selection of the pre-filter not many other standards, only requires the use of the it has enough life convenient, price cheap, easy replacement, supply.

    Domestic airport projects in the 1990 s,There are many big on the architecture and interior decoration, sometimes you will feel our decoration style than developed countries.People pay attention to the "good steel used in the blade, powder on face", but people can't see air conditioning, so often due to cost reduction.In Shanghai pudong airport air conditioning system in the initial planning, activated carbon filter, finally to F7 filter,But when the engineering design of activated carbon were first cut down, in the further design, finally to F5.

    The new airport terminal use activated carbon filter, this is the first terminal to use activated carbon filter in our country,The next round of airport construction projects, F7 filter at the end of the filter will be mainstream, activated carbon filter will also be a large general configuration of the airport
