Summary of the invention
The object of the invention is to provide a kind of buried underground workshop all-pass wind-warm syndrome, wet sub-control system, reaches energy saving economy, environmental protection, does not take the purpose of fabricating yard.
For realizing above-mentioned purpose, the present invention takes following technical proposals:
Buried underground workshop all-pass wind-warm syndrome of the present invention, wet sub-control system comprise gas mixing air channel, and said gas mixing air channel air inlet does not communicate with there being the tailwater gallery of pressure inner chamber, and its gas outlet communicates with underground workshop is indoor; Said Hydropower Station Underground is indoor to communicate with fan inlet, communicates with the pressure fan air inlet through airduct through the air channel respectively; Said pressure fan air outlet communicates with gas mixing air channel.
Gas outlet, said gas mixing air channel is controlled demanding underground power house inner chamber and is communicated with temperature, humidity; Said temperature, humidity are controlled demanding underground power house inner chamber and are required low underground power house inner chamber to communicate through the air channel with temperature, humidity control; Said temperature, humidity control require low underground power house inner chamber to communicate with fan inlet, communicate with the pressure fan air inlet through airduct through the air channel respectively.
The invention has the advantages that the external environment fresh air indoor through there not being the tailwater gallery of pressure introducing Hydropower Station Underground; Because the natural heat exchanger that cold storage bodies such as gallery water body and rock surface constitutes; Carry out the dehumidification of damp and hot exchange desuperheat with outdoor high temperature, highly humid air, reduced the air absolute moisture content that new wind is brought underground power house in a large number.The relative humidity of considering air inducing is greater than 90% humidity considerably beyond the underground power house environmental requirement; At this moment carrying out calculation control according to the humiture index; High temperature air draft in the chamber of going to the factory partially and low temperature, high humidity (relative humidity is high) cold wind are mixed in gas mixing air channel, heat up and send in the underground power house after falling wet process.Since during ventilating system of the present invention operation with draw buried power station do not have press tailrace tunnel cold air as temperature, the wet working medium of regulating, saved the mechanical refrigeration device and the apparatus of air conditioning; Therefore, realized energy-conservation, environmental protection, do not take the purpose in an interior erection space and place.
