Referring to fig. 1, there is shown a schematic structural view of a self-cooling blower room 100 according to a preferred embodiment of the present invention. A blower 110 is typically provided within the blower room 100 for providing a desired air volume for other equipment operation. Of course, in addition to the blower 110, it is often necessary to provide other equipment for maintaining the proper operation of the blower room 100. The blower 110 and these devices are required to be ventilated and cooled during operation. In order to improve the quality of the acoustic environment in the factory where the blower room 100 is located, noise treatment needs to be performed on the blower 110 and its ventilation system, so as to effectively reduce the noise value in the factory.
In order to ventilate and dissipate heat and reduce noise of the blower room 100, such as in the illustrated embodiment, the present invention provides a method for controlling noise of the self-cooling blower room 100, so as to utilize the air intake of the blower 110 itself to cool the blower 110 itself and other devices in the blower room 100.
Referring specifically to fig. 2, the noise control method of the self-cooling blower room 100 according to a preferred embodiment of the present invention includes S1: air quantity Q required by heat dissipation of blower room 100 is calculated 1 。
Air quantity Q 1 Specifically, the following formula can be adopted for calculation:
Q 1 ＝P/(ρ·C p ·Δt)
wherein: p is the heat dissipation capacity (W) of the equipment in the blower room 100, and is generally calculated according to 5% -10% of the rated power of the blower 110; ρ is the density of air (kg/m) 3 )；C p Specific heat of air (J/kg. Deg.C); Δt is the temperature difference (DEG C) between the air at the outlet 112 of the blower 110 and the air in the intake passage 150, and is usually selected at 10 to 20 ℃.
In the process of calculating and obtaining the air quantity Q required by the heat dissipation of the blower room 100 1 After that, step S2 is performed: judgment of Q 1 Rated air quantity Q with blower 110 2 Is of a size of (a) and (b).
Then, step S3 is performed: if Q 1 Not less than Q 2 Description will be made of rated air quantity Q of blower 110 2 Cannot meet the air quantity Q required by the blower 110 and other devices in the blower room 100 for heat dissipation 1 It is difficult to utilize the air inlet of the blower 110 to realize the cooling of the blower 110 and other devices in the blower room 100, and other methods need to be considered to be adopted to finish the scheme; if Q 1 Less thanQ 2 The description can use the air intake of the blower 110 to cool the blower 110 itself and other devices in the blower room 100, and the process proceeds to step S4.
