In the figure: 1. the air conditioner comprises a box body, 2 parts of an interlayer, 3 parts of an exhaust pipe, 4 parts of a silencing hole, 5 parts of a fan, 6 parts of a second silencing cover, 7 parts of an active noise control system, 8 parts of a first silencing cover and 9 parts of an air inlet.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, a silent outdoor compensation box according to a preferred embodiment of the present invention comprises a box body 1, wherein an interlayer 2 is disposed on a side wall of the box body 1, a flame retardant and sound-deadening material is filled in the interlayer 2, a plurality of sound-deadening holes 4 communicating with the interlayer 2 are formed in an inner wall of the box body 1, a first sound-deadening cover 8 is covered on an air inlet 9 at a bottom of the box body 1, an air inlet is formed in a side surface of the first sound-deadening cover 8, it should be noted that the air inlet is not formed in an upper end of the first sound-deadening cover 8 to block noise through the upper end of the first sound-deadening cover 8, a dust-proof net is laid on the sound-deadening cover to ensure cleanness inside the box body 1, sound-absorbing cotton is laid on an inner wall of the box body 1, a second sound-deadening cover 6 is covered on an inner side of a fan 5 at an upper end of the box body 1 to block noise from escaping from an air outlet of the fan 5, air-deadening hole 4 is uniformly provided with air outlet holes, the outside of fan 5 is connected with exhaust pipe 3, exhaust pipe 3 is buckled downwards, reduces the height of wind making an uproar, and then reduces propagation distance, just be provided with initiative noise control system 7 in the box 1.

It is noted that the outdoor compensation box is equipped with an active noise control system 7(ANC), which is a noise reduction method for controlling the original sound signal by artificially and purposefully generating a canceling sound signal in a designated area using an additional sound source. According to the Young's wave interference principle, the secondary sound source of the controlled sound source is used for generating sound waves with the same amplitude and opposite phase with the primary sound source of the original sound source, so that the secondary sound source and the primary sound source generate coherent cancellation in space, and a silencing ' dead zone ' can be formed in a certain area, so that the purpose of noise reduction is achieved.

Preferably, noise control is real-time control, a large calculation amount is needed to have a self-adaptive function, and with the continuous development and maturity of chip technology, the DSP becomes a core component of a modern intelligent controller, so that a system can continuously track changes of noise sources and environments, controller parameters are automatically selected, the optimal noise reduction effect is guaranteed, and the noise active system is small in size, light in weight, relatively low in price and almost free of influence on the structure and the working characteristics of an outdoor compensation box.

When the mute-type outdoor compensation box provided by the utility model is applied, the box body 1 is provided with the interlayer 2 with the flame-retardant silencing material, so that the sound insulation effect is enhanced, and the silencing holes 4 are arranged, so that the noise in the box body 1 enters the interlayer 2, and the flame-retardant silencing material is utilized to absorb the noise, thereby achieving the effect of dual noise reduction; in addition, noise reduction cotton is adhered and paved in the box body 1 to absorb noise for the second time, and the first noise reduction cover 8 is arranged at the air inlet to prevent the noise from directly transmitting out of the box body 1, so that the effect of blocking reflection is achieved, and the air inlet hole ensures the air flow quantity in the box body 1; moreover, the exhaust pipe is arranged to change the trend of hot air in the box body 1 extracted by the fan 5, so that exhaust noise acts near the ground, and the noise diffusion is blocked by utilizing the unevenness of the ground.

On the basis of the embodiment, the flame-retardant silencing material is flame-retardant cotton, so that the flame-retardant effect is achieved while noise is reduced.

Preferably, each silencing hole 4 is covered with a dust screen, so that the flame-retardant cotton is prevented from falling into the box body 1, and the internal environment of the box body 1 is prevented from being polluted.

On the basis of the above embodiment, the arc transition at the bending part of the exhaust pipe 3 ensures smooth flow of the gas in the exhaust pipe 3, and avoids generating impact noise.

For better technical effect, the pipe diameter of exhaust pipe 3 dwindles gradually, and the pipe diameter of the one end that exhaust pipe 3 and box 1 are connected is the biggest, utilizes the blind angle amortization to keep away from to make the noise diffuse reflection in exhaust pipe 3, offset each other.

Preferably, noise reduction cotton is pasted in the exhaust pipe 3, and wind noise is further reduced through the noise reduction cotton.
