Abstract
The utility model discloses a sidewall overlapping type integrated noise elimination air treatment unit. A shell body is divided into an upper shell body and a lower shell body which are mutually overlapped; an air inlet flange is arranged on the lower shell body; a filter is arranged behind the air inlet flange; an air return section winding type silencer box is arranged behind the filter; an inclined surface cooler is arranged behind the air return section winding type silencer box; the rear part of the inclined surface cooler is communicated with a fan section in the upper shell body; an air supply section winding type silencer box is arranged behind the fan section; and an air supply outlet flange is arranged behind the air supply section winding type silencer box; and a fan in the fan section is arranged on a vibration absorption and noise elimination device. The sidewall overlapping type integrated noise elimination air treatment unit is reasonable in structure and has good working performance.
Description
Technical field
The utility model relates to a kind of air-treatment unit.
Background technology
Along with the progress of economic development, society, human environmental requirement to life, work is more and more higher.The requirement of air-conditioning system is required from simple heat is wet, and then the proposition high requirement such as noise that indoor air quality (as air purity, control of microorganisms etc.), air-conditioning are produced.At present the most outstanding two big classes that have of the noise of air-conditioning system are built, the one, industry itself is to performing in a radio or TV programme as TV station of having high requirements of noise etc., the 2nd, the service of some top grades or working region are as 5 star hotels, 5A level office building etc., and these buildings all have high requirement to the noise of air-conditioning system.
Demand to air-conditioning system improves constantly, and will certainly cause the complexity to air-conditioning system.Power source blower fan and motor that the air-treatment unit is carried because of its air all run up, and all can produce higher noise in running.In the past the noise reduction measure of air-treatment unit itself be not a lot, effect is also not obvious, usually need to reduce noise by ventilation shaft.This will cause the pipeline material of ventilating system and the energy consumption of air conveying constantly to increase, and reduces discharging with low charcoal and runs in the opposite direction.So, if the noise control that can effectively improve air-treatment unit itself has very great help to the intensification of air-conditioning system.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the abutment wall of favorable working performance is folded the integrated noise elimination air-treatment of formula unit.
Technical solution of the present utility model is:
A kind of abutment wall is folded the integrated noise elimination air-treatment of formula unit, it is characterized in that: comprise housing, housing is divided into superimposed two-layer up and down, the air inlet flange is set on lower floor's housing, behind the air inlet flange filter is set, air return section is set behind the filter around the formula silencer box, air return section is provided with the tilting surface cooler behind the formula silencer box, communicate with fan section in the housing of upper strata behind the tilting surface cooler, air supply section is set around formula silencer case behind the fan section, air supply section is provided with the air outlet flange behind the formula silencer box; Blower fan in the fan section is arranged on the shock-absorbing and noise-eliminating device.
The fan section inner walls is provided with the cotton layer of low frequency absorption.Damping shock-absorbing form is adopted on the chassis of lower housing portion.The parallel-moving type access door is set on housing.Blower fan is the airfoil blower fan, and blower motor adopts the direct connection drive form, and the blower fan air outlet adopts soft the connecing of eliminating the noise.
The utility model is rational in infrastructure, and all the section of being provided with is around the profile of tooth silencer of formula structure for the unit blasting air side, and the obstruct return air inlet is transaudient and air outlet is transaudient, can significantly reduce the noise of unit; Adopt box noise elimination blower fan, reduce the fan airflow noise and have sound insulation function, at cabinet wall the low frequency absorption cotton is set and plays the sound-absorbing sound insulation function; Complete machine adopts the measure of chassis damping shock-absorbing, not only effectively reduces the vibrations of unit to the machine room floor, and has strengthened sound insulation function; Surface cooler adopts the design of inclination low speed, except that reducing wind speed, also has flow equalizing function concurrently, can effectively reduce the additional drag of inspiratory flow on the blower fan of upper end; Can utilize gravity to control condensation flow, can reduce the unit internal drag, reduce the unit energy consumption to, cancellation surface cooler water fender; Blower fan is selected the wing type fan of highly effective low noise for use, and efficient height, noise are low; Unit adopts folded formula design, can effectively utilize the machine room space, improves the building utilization rate; Access door adopts parallel-moving type, can just can carry out General Maintenance under minimum space, reduces machine room area; The blower motor direct connection drives, and is installed on the same vibration damping base, and integral vibration damping is checked, and effect is obvious; The blower fan air outlet adopts soft the connecing of eliminating the noise, and the not only vibration that can avoid blower fan to run up can reduce blower fan air-supply noise simultaneously.
