Description
Technical field
The present invention relates to a kind of ventilation heat exchange system field, relate in particular to a kind of automatic dedusting intelligent ventilating system that can the fire prevention interlock.
Background technology
Energy savings, protection environment are created harmonious society, have become the common recognition of the whole society.Along with the communications industry and economic common fast development, a large amount of base station construction of universal needs of communication, the common concern that the air-conditioning power consumption of machine room and power saving cause the communications industry already.Respond national energy-saving and emission-reduction and call, the machine room intelligent energy-saving ventilation system is given birth at once, generally is used for cooling off machine room at present and saves energy and reduce the cost.
The intelligent power saving ventilating system by setting give, the air draft unit, when outdoor temperature is lower than communication base station inner control temperature, directly introduce outdoor new wind air indoor, by the wet exchange of the heat of indoor-outdoor air, effectively with the heat in the base station rapidly to external migration, thereby reach the purpose that reduces the inside of base station temperature.The air-supply unit generally is installed in the lower sidewall in the machine room, and the air draft unit has realized preferably that also the machine room inner bottom part send cold wind, the best heat dissipating state of top thermal wind exhausting in relative another top side wall.This mode has improved heat exchange efficiency greatly, can save 30%～80% (deciding according to the different base station environment) of the annual energy consumption of base station air conditioner.Shortcoming is: because indoor-outdoor air directly mixes, indoor humidity is subjected to the influence of outdoor air, need set up humidification, dehumidifying device; For guaranteeing base station cleanliness factor requirement, need set up screen pack, new wind is purified, and screen pack is very easily stopped up by foreign material such as dust in air, catkin and leaves, and more long obstruction of time is more severe, and the resistance of screen pack is also just more big, the air output of blower fan reduces, finally cause properties of product to can not get performance, therefore must be regular screen pack is cleaned, changes, maintenance workload is bigger.When filtration equipment can not meet the demands, can cause the base station cleanliness factor to descend, influence the safe operation of communication equipment.
Deficiency at above traditional machine room intelligent energy-saving ventilation system, the patent of invention 201010151964.8 of the applicant application and 201010238013.4 and patent of invention 201020271955.8 in mentioned efficient dedusting intelligent ventilating system automatically, the bidirectional automatic dust removal intelligent ventilating system, the novelty of the bidirectional automatic dust removal intelligent ventilating system of no air draft blower fan, but along with the continuous development of technology and enriching constantly of engineering application scene, at the utilization to the intelligent aeration technology of miniaturization activity machine room and small-sized civil engineering base station machine room, we have createed again and have been more suitable for the intelligent ventilating system technical scheme that miniaturization activity machine room and small-sized civil engineering base station machine room adopt.
At the weak point of above traditional machine room intelligent heat-exchange system, the inventor has developed the present invention's a kind of " automatic dedusting intelligent ventilating system of the interlock of preventing fires ".
Summary of the invention
