The most single sealing joint strip form of the seal form of efficient air distributor filter in the market, structure is single,
There is air leakage phenomena, thus cause the wind not filtered through air filter to enter directly in clean room, make clean room reach not
To requiring.Prior art air outlet structure as it is shown in figure 1, wind is sent by the air outlet of air conditioning unit 10, when sending blast for+
550pa.Blast is that the wind of+550pa enters in the casing 11 of air outlet device but without blast during air filter 13
For+520pa, blast be the wind of+520pa in clean room 14 delivered to by air filter 13, the blast in clean room 14 is+
20pa.As it is shown in figure 1, casing 11 inner surface of air filter 13 and air outlet device is sealed by sealing joint strip 12.
Wind blast inside the casing 11 of existing air outlet device owing to filtering without air filter 13 is+520pa, Jing Guokong
It is+20pa that the wind that air filter 13 filters enters into the blast of clean room 14, without the blast of the wind that air filter 13 filters
Blast more than the wind filtered through air filter 13.The form using single sealing joint strip to carry out sealing cannot realize the closeest
Envelope, wind can filter without air filter 13 and be directly entered clean room 14, thus cause clean room 14 not reach requirement.Based on
This, the new and effective supply air system of one that this utility model embodiment provides.It is described below by embodiment.
As in figure 2 it is shown, the new and effective supply air system of one that this utility model embodiment provides, including in both ends open
Empty cylindrical shell 20, an opening of shell 20 are air intake vent, and another opening is air outlet, and air outlet position is provided with
