Summer condition：Fresh air enters fresh air adjusting section from new air-valve and is mixed after initial effect filtering section filters with return air outside factory,
By surface cooling section cooling humidity reduction, the return air entered into secondary return air Duan Yucong secondary returning air-valves mixes reheating, by pressure fan
Wind turbine in section is delivered to air funnel, and then enters in industrial premises.Return air in industrial premises is by primary retirn air valve through height
After imitating fillter section filtering dust, then by the wind turbine conveying in return fan section, passes through and adjust exhaust valve, secondary returning air-valve and mixed wind
Valve, a part of return air are expelled to by exhaust valve outside workshop, a part of return air by mixer selector valve enter fresh air adjust section in from
New air-valve enters fresh air and is mixed, and remainder return air carries out mixing reheating with condensed fresh air.
Winter condition：
Fresh air, which from new air-valve enters fresh air and adjusts section, outside factory mixes with return air and is filtered through initial effect filtering section, into secondary return air
After the return air mixing reheating that Duan Yucong secondary returning air-valves enter, by bringing-up section and humidifier section warming and humidifying from blower section
Wind turbine is delivered in air funnel, and then is entered in industrial premises.Return air in industrial premises is by primary retirn air valve through efficient mistake
After filtering section filtering dust, then conveyed by the wind turbine in return fan section, by adjusting exhaust valve, secondary returning air-valve and mixer selector valve, one
Part return air is expelled to by exhaust valve outside workshop, a part of return air by mixer selector valve enter fresh air adjust in section with from new air-valve
The fresh air of entrance is mixed, and remainder return air carries out mixing reheating with the fresh air after primarily efficient filter.
Transition season operating mode：Surface cooler and heater are out of service, warm according to being designed in new air temperature outside workshop and workshop
The requirement of degree, by adjusting fresh air volume and exhaust air rate.Air purification process is the same as summer and winter condition.
Above-described embodiment is only to clearly demonstrate examples made by the present invention, rather than the restriction to embodiment.For
For those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.Here without can not be also exhaustive to all embodiments.And the obvious variation or change thus amplified out
It is dynamic to be still in the protection scope of this invention.
