⑥ Air Distribution

The purpose of air distribution is resonally organising the flow and distribution of the air in a room, then it can better satisfy the technique and comfort requirements of temperature and humidity, cleanliness.

Here are some traditonal methods of air supply:
1. side-supply and side-return
Its advantage is that it can easily satisfy the requirement of unequal air parameter.
2. up-supply and down-return
It's suitable for high requirement of pricision.
3. mid-supply and down-return
It's suitable for high and large room, and it can save energy.
4. down-supply and up-return
It is suitable the rooms whose heat source is near the roof, such as computer room. However, the temperature difference shouldn't be to big, in case of the occupants feeling uncomfortable.
5. up-supply and up-return
Attention: be aware of air flow short circuit.


Here is a new method:
venlitation exchange
It can perfectly use the theory of heat source produce heating power, and exhaust gas would flow up. Compare with the traditional one, it can save energy at least 20%. It is becoming more and more widely use all around the world.
