Description
Technical field
The present invention relates to ventilation field, in particular to a kind of indoor ventilation system.
Background technology
The ventilation exhaust equipment in existing laboratory is vent cabinet and enclosure etc., is the point-like air discharging facility for having and being directed to,
Substantially it is not directed to the air draft scheme of integral room.And dependence of the said exhaust equipment to overall exhaust system pipeline is very bright
It is aobvious, can not be again in laboratory to smell progress if position and roof exhaust fan without pre-designed air draft pipe well
Discharge.This results in different floors and room the problem of public same exhaust system, and the gas of different experiments room discharge exists
Mixed in pipeline, have potential safety hazard.Air quantity can not also be adjusted, can shadow while a laboratory ventilation system reform is carried out
Ring air quantity and the distribution in other laboratories, it is also possible to the situation for causing different experiments room to pour in down a chimney.
In the ventilating system without air-makeup system, each laboratory is only to realize that laboratory internal is empty by discharge air
Gas is fresh, then the air that will certainly be sucked in corridor, and continuing can be to corridor, and elevator Lou Ti halls, gate causes negative pressure, and
This negative pressure is uncontrollable and makes up, and the pressure of each floor can be variant, and air can flow between each floor, and the one of whole building
Two layers occur the uncontrollable situation of temperature, and all can all not cause bottom mistake by mending the laboratory building of wind processing in winter
Cold situation, has had a strong impact on experimental situation.Even in laboratory, if without air-makeup system, will also result in room door can not beat
Open or close situation about closing.
