Description
Technical field
The utility model relates to the ducting system in heating and ventilation project, in particular to a kind of slim bottom for subway send bottom to return
Ducting system.
Background technique
Subway now has been used widely in the whole world, especially in economically developed city, since traffic above-ground connects
Nearly saturation, traffic jam have seriously affected the rhythm in city, therefore developing subway transportation is best selection, it can both mitigate
The pressure of traffic above-ground, and flow of the people can be accelerated, to improve the development rhythm in city.But based on the above various noise reduction measures without
Method meets simultaneously, and the noise problem of railcar still annoyings passenger.In recent years, Chinese orbit construction technology and vehicle manufacture
Technology high-speed development, client gradually pay attention to noise reduction problem.
In railcar in air-conditioning system field, the structure type that bottom send bottom to return is most typically, most common air duct system
System.The characteristics of air duct that bottom send bottom to return: 1, the air duct that bottom send bottom to return is in current domestic subway train ducting system using the most
One of common structure, it has technology maturation, and versatile advantage, the change workload of disparity items similar structures is very
Small, structure is simple, is less prone to later period constructive interference even interface and does not correspond to.2, for train height limitation and vehicle
The requirement of weight, the air duct pattern that bottom send bottom to return have height low (effective height is usually within 150mm inside air duct), light weight
(small in size, material utilization amount is few for change；The lower material of density can be selected) the advantages that.3, the air channel structure that bottom send bottom to return is due to entirety
Highly lower, flow velocity is higher inside main air duct, and the noise and vibration that air-flow flowing generates are easy to be passed in compartment by air duct,
Noise is excessively high to influence whether interior environmental amenity degree.In recent years, vehicle loss of weight is the project of main engine plants' primary study, by
In exceedingly pursuing lightweight, air duct is all changed from structure and material, using the lower foam board of density, by air duct

Vibration and resonance.2, air conditioner of subway vehicle shell also uses stainless steel or aluminum alloy material substantially, while guaranteeing good appearance,
Also because shell has biggish intensity, reduction vibration is played, the effect of noise is reduced.3, level Four or six grades of motors are generallyd use
Condensation fan and evaporation fan, total noise of centrifuge are generally larger.4, reinforce the sound insulating seal inside and outside compartment, adding including structure
By force, the type selecting etc. of acoustic material, is conducive to avoid in noise transmission to compartment, influences passenger comfort.5, lower using density
Composite board, surrounded, fixed using aluminium alloy, but intensity be not so good as aluminium alloy air duct, noise reduction, damping effect are bad.6, it selects
With centralized return air system structure, be connected with the evaporation fan air-flow of air-conditioner set, noise is transferred to guest room by return air inlet.The prior art
Technological deficiency be: do not send the material of bottom air -return duct and noise reduction, damping effect to carry out for Journal of Sex Research at extra-thin bottom, vehicle
Noise reduction effect is to be improved.
