The heat exchange between air-flow in existing air intake passage and air exhaust passage, can reclaim a part of heat.
Air cleaner in the present embodiment is chosen according to GB/T14295-2008, selects flat air mistake
Filter, wherein the slightly selection of filtering material filtrate capable of washing of effect air cleaner, the replaceable filter of selection of filtering material of middle effect air cleaner
Material, sub- efficient and high efficiency particle air filter the disposable filtrate of selection of filtering material.
Under normal circumstances, air port is all to use standard air port, the minimum dimension 100mm*100mm in general rectangle air port, its
It is remaining to increase by modulus of 10mm, also there are customization air port, that is, nonstandard air port.The selection gist in air port is according to wind speed and air-supply
Distance, selected according to wind speed and apart from according to result of calculation, but this air port on VMC typically all need not
Calculate, but because it is under needing to check, according to GB/T14295-2008 high efficiency filters that high efficiency particulate air filter, which puts tail end air port,
Device wind speed will be controlled within 1.5 metre per second (m/s)s, and in order to reduce resistance, wind speed preferably takes low spot again.
Figure below is efficiency and resistance of the filter under nominal air delivery：
Efficiency and resistance under the filter nominal air delivery of table 3
According to upper table, those skilled in the art can adjust the area of passage of blast pipe to meet the needs of, larger
Blast pipe can be nonstandard pipeline that galvanized iron sheet scene is made or the plastic pipe of customization in system, common wind
Pipe also has rower, can be selected according to air quantity air intake.
General to require in VMC, intake should change space air one time in 1 hour.According to room
Volume, the intake of each second in the air intake passage of outdoor purification main frame can be calculated, total blast volume is then assigned into each room
At interior tuyere structure, and blast velocity control can be adjusted into wind speed, blower fan in below 1.5m/s by adjusting the flow-passing surface in air port
Chosen also by intake.Need not be strict as Tool subject mathematics in engineering, also say above, in order to reduce resistance
Power, wind speed preferably take low spot again, to allow wind speed to be less than the air ports size that 1.5m/s takes a big rank, until wind speed is less than
1.5m/s, naturally it is also possible to increase the quantity of air inlet, after one, room air port is ensured, increased inlet number can be with
Determined according to the area in room and suitable set location.
It can be arranged in the indoor tuyere structure that premises is set on furred ceiling, in the finishing of existing house, top is general
Stereovision is pursued, is just that the little room of area can also set a circle furred ceiling at the top of surroundings wall, air port is arranged on
The floor height in room will not be additionally reduced on furred ceiling, the sensation given people is preferable, can be with because furred ceiling is also provided on ceiling
On the ceiling being connected between thinking air port and being.
