Description
【Technical field】
The present invention relates to a kind of laboratory ventilation system, can effectively solve negative pressure that laboratory formed during air draft,
The problem of temperature fluctuation is bigger and energy waste.
【Background technology】
At present large-scale experiment room due to exhaust air rate it is big, the problem of all there is indoor negative pressure is excessive and temperature bad control,
Since draught cupboard in laboratory and other exhaust equipments are more, cause indoor negative pressure bigger, some laboratories are not due to having benefit wind
Device or mend air quantity it is inadequate, wind can only be got in from gaps such as doorway, windows, cause indoor negative pressure excessive, to make door and
Window is difficult to open indoors；And traditional constant indoor temperature be heated or freezed to reach required temperature by air-conditioning, but
Winter, air-makeup system did not had heating device again in addition, so as to cause room is filled into since draught cupboard is directly discharged indoor hot-air
Interior air temperature is very low, and indoor temperature is caused to be unable to control, and wastes the energy of air-conditioning；Otherwise summer is also；Secondly tradition
The benefit wind that wind is all constant power is mended in laboratory, is not directed to each room exhaust air rate and is carried out rationally mending wind and not utilize rationally
The return air in part room carry out cycle mend wind, such as when some room equipment close after, still according to original air quantity into
Row mends wind so that indoor positive pressure is excessive, is unfavorable for the discharge of poisonous and harmful substance, as long as and entire company has when winter
The place in gap can all enter the wind, and all there is detrimental effect for personnel and equipment, and waste the effect of air-conditioning, and be directed to
The benefit wind devices used now lack fresh air purification device, the fresh air and return air filled into cannot be guaranteed to reach occupational exposure limit and
Room air requirement.
A kind of laboratory ventilation system of applicant's design, can help to solve the problems, such as more than.
【Invention content】
The bigger problem of the negative pressure and temperature fluctuation that are formed during air draft for laboratory, the present invention provide a kind of
Easy to operate and reasonable energy utilization ventilating system is closed according to the return air in each room exhaust air rate and bound fraction room
Reason mends wind, and carries out heating or the refrigeration of required temperature before entering each room to the mixing wind of fresh air and return air, and interior is made to reach
Stablize to pressure balance and temperature, meets the requirement of laboratory environment.
The technical solution used in the present invention is as follows：
A kind of laboratory ventilation system, including mend wind wind turbine, exhaust fan, air flow sensor, volume damper, constant temperature control
Device, absorption tower, fresh air purification device, return air duct and connecting line processed；It is logical that the benefit wind wind turbine is located outside suitable position
Connecting line is crossed with indoor each room to be connected；It is each with interior by connecting line that the exhaust fan is located outside suitable position
Exhaust equipment is connected in room, and the air flow sensor is located on the main exhaust duct in each room；The volume damper with
Thermostatically-controlled equipment is located on the main secondary air channel road in each room；The air flow sensor counts total air draft per second in each room
It measures and feeds back to and mend wind wind turbine, mend wind wind turbine and benefit air quantity is controlled by volume damper, the fresh air covered is returned with part room
Wind is purified to be heated or freezed by thermostatically-controlled equipment again by fresh air purification device and be got in together；The benefit
Wind wind turbine mends the 70%-90% or so that air quantity is each room exhaust air rate to each room；The thermostatically-controlled equipment can be with
It requires temperature to be configured according to interior, can realize that refrigeration, winter can realize heating in summer；The fresh air purification device can be with
It is filtered purification to filling into indoor air, ensures that the indoor fresh air of feeding is non-hazardous to human body and environment；The absorption tower
It is connected with exhaust fan and can be one or more according to different function lab setup, for differences such as acid, alkali, organic volatiles
Emission carries out installation settings, reduces and is directly discharged to outdoor nuisance quality；It is described to mend benefit wind of the wind wind turbine to Office Area
Amount is the 10%-30% or so of total exhaust air rate；Each room in laboratory mend wind mode can according to the requirement in each room into
It blows on row, lower air-supply or up and down air-supply；The air draft uses local exhaust mode；It is described fill into indoor air by fresh air and
The return air two parts in part room form, and each room is got in by fresh air purification device after mixing；The part room
Return air amount summation accounts for the entire 20-50% for mending air quantity；By the benefit wind to Office Area, Administrative Area is made to reach barotropic state, prevented
Only cross contamination between Laboratory air and Administrative Area air, reaches a whole balance, and can as needed into
The benefit wind in the multiple rooms of row, when laboratory is extended or has other rooms to need to carry out benefit wind, as long as in exhaust fan and benefit
In wind wind turbine rated power, only need installation pipeline and thermostatically-controlled equipment with mend wind wind turbine be connected can normal use, reduce
The expense in later stage.
The innovative point of the present invention is to provide a kind of easy to operate and reasonable energy utilization ventilating system, according to each room
Wind is rationally mended in exhaust air rate progress, and to the mixing wind of the return air of fresh air and part room composition into needed for progress before each room
The heating of temperature or refrigeration make interior reach pressure balance and temperature stabilization, meet the requirement of laboratory environment, and rationally utilize
Return air resource reduces humiture fluctuation and energy consumption.
