Abstract
The utility model discloses an air conditioner, and comprises an air duct. An air duct main body is formed by porous material 1 with good wholeness, the bubble holes of the material 1 penetrate form the surface to the inner part, the bubble holes are mutually connected into continuous air bubbles, and the diameter is below 1 mm; the outer surface takes rigid material as a protective layer 2, and a certain hollow cavity 3 is left between the porous material 1 and the protective layer 2. The air conditioner can be a cabinet type air conditioner, and can be also a window type air conditioner. Because of starting with the air duct material, the utility model uses the porous material to make the air duct of the indoor unit of the air conditioner, adopts sound absorbing measure in the approach of noise transmission, effectively reduces noise generated when an air conditioning operates, and provides a brand new conception and a method for the noise reduction of the indoor unit of the air conditioning.
Description
Technical field
The utility model relates to air-conditioner, more particularly, relates to the air-conditioner in a kind of porous type air channel.
Background technology
Existing indoor side noise cabinet type, window air conditioner is mainly determined by factors such as air channel, fan, heat exchangers, tradition noise reduction mode mainly reduces noise level by transforming above-mentioned modular construction, grope by a large amount of tests, to obtain more excellent organization plan, the time and the fund input amount that often need are bigger, but comparative benefit is not high.
The utility model content
The technical problems to be solved in the utility model provides a kind of new air-conditioner, can effectively reduce the air-conditioning noise.
The utility model technical problem solves like this, constructs a kind of air-conditioner, and its air channel is made by porous material, reduces the technology of air-conditioning noise by its good sound absorbing capabilities.Specifically, this air-conditioner comprises the air channel, and this air channel main body is made of the material 1 of porous and good integrity, and the abscess of this material 1 is through to inside by the surface, and interconnecting between abscess becomes continuous air bubbles, and the aperture is below 1mm; Appearance as armour layer 2, and is stayed certain cavity 3 with rigid material between porous material and armour layer.
Implement air-conditioner of the present utility model, owing to start with from material, use has porous material and makes the air conditioner room unit air channel, in the approach of noise transmission, adopt the measure of sound absorption, the noise that produces when effectively reducing operation of air conditioner is for the indoor apparatus of air conditioner noise reduction provides a kind of new thinking and method.
Description of drawings
Fig. 1 is the structural representation of the air channel structure of explanation the utility model air-conditioner.
The specific embodiment
In conjunction with the accompanying drawings, further specify the air channel structure of the utility model air-conditioner.As shown in Figure 1, the air channel main body is made of the material 1 of porous and good integrity, and the abscess of this material is through to inside by the surface, and interconnecting between abscess becomes continuous air bubbles, and the aperture is below 1mm; Appearance as armour layer 2, and is stayed certain cavity 3 with rigid material between porous material and armour layer, to obtain high low frequency sound-absorbing effect.
The sound absorbing mechanism that the utility model air-conditioner now is described is as follows: when sound wave incides porous material, mainly caused the decay of sound wave by following mechanism.Cause that interstitial air moves back and forth when propagating in the space of sound wave between grain, be subjected to the influence of grain to be not easy motion at the air of hole wall surface, therefore in the air movement speed in grain gap with regard to faster or slower, promptly have velocity gradient.Because the viscosity of air can produce corresponding viscosity resistance, makes acoustic energy constantly be converted into heat energy, thereby makes SATT.
Claims (3)
1, the air-conditioner in a kind of porous type air channel, comprise the air channel, it is characterized in that, described air channel main body is made of the material (1) of porous and good integrity, the abscess of this material 1 is through to inside by the surface, and interconnecting between abscess becomes continuous air bubbles, and the aperture is below 1mm, be provided with the armour layer (2) of rigid material in described air channel main body (1) appearance, between porous material air channel main body (1) and described armour layer (2), stay certain cavity 3.
According to the described air-conditioner of claim 1, it is characterized in that 2, described air-conditioner is a cabinet air conditioner.
According to the described air-conditioner of claim 1, it is characterized in that 3, described air-conditioner is a window formula cabinet air conditioner.
