The pattern of kind.
Take after above technical scheme, the beneficial effects of the utility model are：
1st, air cleaning：In general clean room space system, empty gasification process uses air cleaner.Normal conditions
Under, install after roughing efficiency air filter and medium effeciency filter, air purity can reach 10000 grades.And for ultra-clean requirement
Clean room should also install high efficiency particulate air filter.So, air purity can reach higher（Such as 100 grades of even more highs）.Filter
The attached dust that sunk during long-term use, on filtrate will slowly increase, and can so increase gas-flow resistance, influence the fortune of whole air-conditioning system
OK.Therefore, automatic detection and alarm should be carried out to the gas-flow resistance variable force of filter in engineering.Generally measured using differential pressure method
Pressure difference Pd before and after filter, and this differential pressure signal is shown and alarmed according to the differential pressure limit value of setting, so as to cleaning in time
Or change.
2nd, temperature control：A, the control once heated, air are once heated and also known as preheated, be for heat fresh air or
Heat the mixing wind of fresh air and primary retirn air.Once heating is normally only used for winter terribly cold area, prevents fresh air with once returning
Saturation is reached after wind mixing, water smoke or icing is produced.Once heating is also applied to the ultra-clean air-conditioning that mixed once does not allow to change
In system.When being heated using steam or hot water, the general control valve opening using control steam or hot water realizes temperature
Control；When using electrical heating, by thyratron transistor electric controller, its heating electric power is controlled to realize temperature control.It is B, secondary
The control of heating and three heating
Air secondary heating be usually provided at after surface cooler or secondary return air mixing section after.The purpose of reheating is that having
In the case of relative humidity requirement, in order to ensure the temperature in wind pushing temperature or air conditioning chamber.Its control mode and once heat
Situation is essentially identical.Three heating, again into finishing heat, are typically, in high accuracy temperature control, to be set for fine tune temperature
Bringing-up section.It controls as the case may be with reference to above-mentioned principle to implement.
3rd, humid control：In A, humidification process and control, clean room Air-conditioning Engineering, wet operations be usually in the winter time or
Carried out when transition season is air-dried.The method of air wetting is relatively more.Usual opening using seam humidifier and electric moistening device
Close control or power adjusting.During steam humidification, required according to humid control, can be by entering the control of line position formula to magnetic valve or using
Two regulating valves continuously adjust to realize.B, dehumidifying（Dry）Processing and the conventional surface cooler of control air cool drying processing
To complete.The cold processing to air of table etc. clammy but two kinds of processing procedures.It is to pass through when carrying out humid control using surface cooler
Adjust the refrigerant of surface cooler（Such as chilled water）Flow is realized., can be by increasing cold valves when humidity is higher than desired value
Aperture increases its flow, realizes dehumidifying（That is drying）Processing；Otherwise flow is reduced, humidification process is realized.It should be noted that
Due to the physical property of air, the control of its humidity is relatively complicated, and method is also more.Moreover, the temperature and humidity of air
Two parameters influence each other again during regulation.Such as some reasons raise indoor temperature, cause the full of water vapor in air
With partial pressure change, it in the case where absolute moisture content is constant, will reduce relative humidity.Therefore, wherein a certain parameter is carried out
During regulation, it can also cause the change of another parameter.Dehumidifying regulation is for example carried out using surface cooler in summer, when opening big cold valves,
While humidity is recovered normal, also reduce temperature.Therefore, all should fully it be examined when technological design and automatic control schemes are designed
Consider this feature.
4th, over-pressure control：Should be greater than 4.9Pa between China's national Specification, different stage toilet, clean area with it is non-
9.8Pa is should be greater than between clean area.Structure in toilet etc. is determined substantially, in the process of running, keeps malleation to pass through
Resh air requirement or return air amount is controlled to realize.I.e. by controlling the aperture of new air door or return air door to realize.
5th, humiture is monitored：In extensive clean room using traditional wire temperature and humidity monitor construct cumbersome, cost it is high,
Increase and adjustment test point inconvenience, and the deficiency of wire transmission is compensate for using wireless humiture sensor network technique, it can expire
Multinode temperature and humidity measurement in the extensive clean room of foot.
6th, other controls and air conditioner energy saving：For dust proof workshop, except it is above-mentioned it is essential to ensure that technical indicator show, also one
A little requirements in terms of safety and energy-conservation.With reference to engineering practice for many years, mainly there is the following aspect：A, blower fan event
Barrier alarm, by the air current state of detection blower fan judge blower fan whether normal work.If because of the original such as burn-down of electric motor or belt loosening
Because causing blower fan to stall, it should alarm immediately；B, fan frequency conversion control
, can be to machine to keep stable malleation or certain fresh air/air returning ratio in dust proof workshop（Motor）Revolution is implemented
VFC.It was verified that VFC is than simple throttle opening regulation control effect more preferably, and it can significantly save electricity
Power is consumed.Because within air-conditioning systems, the conveying for fresh air/return accounts for the maximum ratio of power consumption.And airdoor control is actually
Pass through throttling arrangement（That is air door）To realize the change of air-flow；C, pump variable frequency control, when a pump is to a regulating system, are used
Frequency control（Water pump revolution）Realize that flow control ratio uses throttling arrangement（That is regulating valve）It is preferred.This mode is not only embodied in
Control effect more preferably, is significantly saved in power consumption while being embodied in；D, energy-conservation program, due to answering for computer control system
With making Energy Saving Control become a reality.I.e. in addition to the above-mentioned Energy Saving Control means implemented to air-conditioning system process characteristic, computer
Control can also realize such as enthalpy value control, dark cycle, night wind purification, optimal start and stop, zero energy area.Certainly, it is special for some
Fixed clean room, its energy-conservation program should be worked out according to its concrete condition, to reach optimal energy-saving effect.
