It cannot be guaranteed that grottoes internal gas pressure reaches the required standard of mural painting protection, ruins may be caused potentially hazardous.
Accordingly, it would be desirable to work out a kind of air pressure, humidity sensor, controller, frequency conversion fan coordinated operation be applicable to grottoes ruins
The linkage aeration system of guard space, according to unlatching and the air-supply value of emchanical air supply system of indoor environment parameter control system, with
This reaches to ventilate and the purpose of Ruins protection.
Utility model content
The purpose of this utility model is the ventilating system providing a kind of grottoes ruins pressure reduction to control, to solve above-mentioned technical problem.
For realizing object above, this utility model adopts the following technical scheme that:
The ventilating system that a kind of grottoes ruins pressure reduction controls, including baroceptor, controller, fan frequency converter, blower fan and electricity
Dynamic ventilating blind；Electrically ventilating BAIYE is installed on grottoes door；It is disposed with some to for monitoring grottoes inside and outside electrically ventilating BAIYE
The baroceptor of door inner and outer air pressure；The outfan of baroceptor connects controller, the outfan connecting fan converter of controller
With electrically ventilating BAIYE, the control end of the outfan connecting fan of fan frequency converter, it is used for controlling rotation speed of fan；The air outlet of blower fan
By in pipeline communication grottoes.
Further, the inside and outside of grottoes door does not the most only have two humidity sensors, and the outfan of humidity sensor connects the defeated of controller
Enter end；The air inlet of blower fan connects the air outlet of dehumidifier；The outfan of controller connects the control end of dehumidifier.
Further, being additionally provided with temperature sensor in grottoes door, the outfan of temperature sensor connects the input of controller；Remove
The air inlet of wet machine exports with the air intake heat exchange of refrigeration machine and is connected；The outfan of controller connects the control end of refrigeration machine.
Further, controller is by wired or wirelessly connecting fan converter, dehumidifier and refrigeration machine.
Further, fan frequency converter, blower fan, dehumidifier and refrigeration machine may be contained within outside grottoes.
Relative to prior art, this utility model has the advantages that
This utility model be solve these type of grottoes such as Mogao Grottoes when wet weather in the cave outside highly humid air to the wet problem of cave internal diffusion biography, it is provided that
A kind of ventilating system, it keeps pressure-fired in can making grottoes, prevents the dampness to cave internal diffusion, in order to the most stable in maintaining cave
And the air ambient of suitably mural painting protection.There is good prospect of the application, can be widely used in Mo kao grotto at Dunhuang etc. and lead in grottoes
Wind requires higher grottoes environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the ventilating system that a kind of grottoes of this utility model ruins pressure reduction controls.
Detailed description of the invention
Referring to shown in Fig. 1, the ventilating system that a kind of grottoes of this utility model ruins pressure reduction controls, including baroceptor 1, wet
Degree sensor 2, temperature sensor 3, controller 4, fan frequency converter 5, blower fan 6, dehumidifier 7, refrigeration machine 8 and electronic logical
Wind BAIYE 9.
Two pairs of baroceptors 1 it are disposed with for detecting the indoor and outdoor atmospheric pressure of grottoes mouth inside and outside electrically ventilating BAIYE 9 on grottoes door
Power.It is equipped with a humidity sensor inside and outside grottoes door, in grottoes, there also is provided a temperature sensor 3；Baroceptor 1 He
The outfan of humidity sensor 2 connects the input of controller 4；The outfan of controller 4 passes through wired mode or wireless mode
Connecting fan converter 5, dehumidifier 7 and refrigeration machine 8.
The air inlet of dehumidifier 7 exports with the air intake heat exchange of refrigeration machine 8 and is connected, the air inlet of the air outlet connecting fan of dehumidifier 7,
Inside the air outlet connection grottoes of blower fan.
The ventilating system that a kind of grottoes of this utility model ruins pressure reduction controls, grottoes door is externally provided with air pressure transmission in electronic ventilating blind 9
Sensor, the rainy day, relative humidity outside detection cave, when outside cave by ventilating blind 9 outer humidity sensor 2 of installing electronic on grottoes door
When relative humidity reaches more than 60%, humidity sensor sends alarm signal, starts blower fan by controller and starts to indoor air-supply,
Increase room pressure, invade indoor with blocks moisture；Meanwhile, on controller control door, electronic ventilating blind 9 is automatically switched off.Grottoes door
Being externally provided with baroceptor, detection cave inner and outer air pressure in upper electronic ventilating blind 9, when air-supply starts, air output is gradually incremented by, until
When baroceptor feeds back to cave internal gas pressure more than the outer 3 ± 1Pa in cave, controller control frequency conversion fan starts at the uniform velocity to blow, until room
Outer humidity sensor display outside relative humidity is when 30 ± 5%, and blower fan cuts out, out-of-blast；Simultaneously electronic on automatic opening door
Ventilating blind 9, makes gravity-flow ventilation inside and outside grottoes.
In temperature sensor perception grottoes, temperature is beyond after design temperature scope, and controller controls refrigeration machine 8 and strengthens or reduce refrigeration
Measure to control the inlet temperature of dehumidifier 7, in the range of temperature is maintained at design temperature in grottoes time final.
This utility model be solve these type of grottoes such as Mogao Grottoes when wet weather in the cave outside highly humid air to the wet problem of cave internal diffusion biography, it is provided that
The ventilating system that a kind of grottoes ruins pressure reduction controls, it keeps pressure-fired in can making grottoes, prevent dampness to cave internal diffusion, with
Just the air ambient that in maintaining cave, relatively stable and suitable mural painting is protected.There is good prospect of the application, can be widely used in Dunhuang
The grottoes environment that Mogao Grottoes etc. are higher to air-conditioning requirement in grottoes.
