Description
【Technical field】
A kind of laboratory ventilation system is the utility model is related to, can effectively solve that laboratory formed during air draft is negative
Pressure, temperature fluctuation is bigger and the problem of energy waste.
【Background technology】
At present large-scale experiment room due to exhaust air rate it is big, all there is indoor negative pressure is excessive and the problem of temperature bad control,
Because fume hood in laboratory and other exhaust equipments are more, cause indoor negative pressure bigger, some laboratories are due to no 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 so that door and
Window is difficult to open indoors；And traditional constant indoor temperature is to reach required temperature by air-conditioning heating or refrigeration, but
Winter, air-makeup system did not had heater again in addition, so as to cause to fill into room because fume hood directly discharges indoor hot-air
Interior air temperature is very low, causes indoor temperature uncontrollable, 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 carried out rationally mending wind for each room exhaust air rate and is not utilized rationally
The return air in part room carries out circulation and mends wind, such as after the equipment in some room is closed, still enters according to original air quantity
Row mends wind so that indoor positive pressure is excessive, is unfavorable for the discharge of poisonous and harmful substance, as long as and whole company has when winter
The place in gap all can air intake, detrimental effect all be present 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 solve the problems, such as the above.
【Utility model content】
For laboratory the negative pressure and bigger temperature fluctuation formed during air draft the problem of, the utility model provides
A kind of simple to operate and reasonable energy utilization ventilating system, enter according to the return air in each room exhaust air rate and bound fraction room
Row rationally mends wind, and makes room into the heating of temperature or refrigeration needed for progress before each room to fresh air and the mixing wind of return air
Inside reach pressure balance and temperature stabilization, meet the requirement of laboratory environment.
Technical solution adopted in the utility model is as follows：
A kind of laboratory ventilation system, including mend wind blower fan, exhaust fan, air flow sensor, volume damper, constant temperature control
Device, absorption tower, fresh air purification device, return air duct and connecting line processed；The benefit wind blower fan is located outside correct position and led to
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 correct 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
Measure and feed back to and mend wind blower fan, mend wind blower fan 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 got in together；The benefit
Wind blower fan mends the 70%-90% that air quantity is each room exhaust air rate to each room；The thermostatically-controlled equipment can basis
Interior requires that temperature is configured, and refrigeration can be realized in summer, and winter can realize heating；The fresh air purification device can be to mending
The air for entering interior carries out filtration, purification, ensures to be sent into indoor fresh air to human body and environment non-hazardous；The absorption tower and row
Wind blower fan is connected and can set one or more according to difference in functionality laboratory, for acid, alkali, organic volatile difference emission
Installation settings is carried out, reduces the nuisance quality for being directly discharged to outdoor；The benefit wind blower fan is total to the benefit air quantity of Office Area
The 10%-30% of exhaust air rate；The benefit wind mode in each room in laboratory can carry out upper air-supply according to the requirement in each room,
Lower air-supply or up and down air-supply；The air draft uses local exhaust mode；The air for filling into interior is by fresh air and part room
Return air two parts composition, each room is got in by fresh air purification device after mixing；The return air amount in the part room is total
With the 20-50% for accounting for whole benefit air quantity；By the benefit wind to Office Area, Administrative Area is reached barotropic state, prevent laboratory
Cross pollution between air and Administrative Area air, reach an overall balance, and multiple rooms can be carried out as needed
Between benefit wind, when laboratory is extended or when having other rooms to need to carry out benefit wind, as long as in exhaust fan and mending wind blower fan volume
Determine in power, only need installation pipeline and thermostatically-controlled equipment with mend wind blower fan be connected can normal use, reduce the expense in later stage
With.
Innovative point of the present utility model is to provide a kind of simple to operate and reasonable energy utilization ventilating system, according to each
Room exhaust air rate is carried out rationally mending wind, and the mixing wind of the return air in fresh air and part room composition is carried out before each room is entered
The heating of required temperature or refrigeration, make interior reach pressure balance and temperature stabilization, meet the requirement of laboratory environment, and rationally
Using return air resource, humiture fluctuation and energy resource consumption are reduced.
