Description

Air handling unit case with sound insulation function

Technical Field

The utility model relates to an air conditioning equipment specifically is an air handling unit case with sound insulation function.

Background

The air handling unit is also called an air conditioning unit, and is a centralized air handling system, which is placed inside an air handling unit box, and originated from a centralized device, and can adjust the temperature and humidity of air through a forced hot air heating and ventilating system for distributing and heating air through air pipes so as to make people feel comfortable.

In the current air handling unit case, the unit case is made of only one layer of iron sheet, so that noise generated by the air handling unit inside the unit case during working is easily transmitted to the periphery and is not easily isolated by the unit case, thereby causing noise pollution and influencing daily use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the unit box is difficult to be isolated by the unit box because only one layer of iron sheet is manufactured, and therefore the noise generated by the air handling unit inside the unit box during operation is easily transmitted to the periphery, thereby causing noise pollution.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an air treatment unit case with sound insulation function, including unit case body, logical groove has been seted up in the front of unit case body, the inside activity that leads to the groove has the closed door, the inner wall of unit case body all is fixed with sound absorption layer A, sound absorption layer A's inner wall is fixed with abatvoix A, the inner wall that leads to the groove is fixed with the sealing strip, the surface of sealing strip is provided with inhales the sound cotton, inhale the cotton surface of sound and set up quantity more than or equal to one's recess, inhale the cotton surface of sound and the side swing joint of closed door, the back of closed door is fixed with sound absorption layer B, sound absorption layer B's the back is fixed with abatvoix B, the front of closed door is provided with the handle bar.

Preferably: the sound-absorbing boards A and B are identical in shape, and the surfaces of the sound-absorbing boards A and B are both arranged roughly.

Preferably: the quantity of sealing strip is two sets of, and two sets of sealing strips all use the vertical axis that leads to the groove to be axisymmetric setting as the symmetry axis.

Preferably: the cross sections of the sound-absorbing boards A and B are isosceles triangles.

Preferably: the sound absorption layer A and the sound absorption layer B are made of inorganic foam sound absorption materials.

Due to the adoption of the technical scheme, the utility model discloses following superiority has:

through setting up sound absorbing layer A, attract layer B, abatvoix A and sealing strip, at the during operation of inside air unit, the noise that produces is at first fallen by abatvoix A and abatvoix B and is fallen and make an uproar, then fall through sound absorbing layer A and sound absorbing layer B and fall and make an uproar, and the gap that seals the door position falls through inhaling the sound cotton on the sealing strip and making an uproar, reduce the propagation of sound, thereby improve syllable-dividing effect, reached and effectively completely cut off the effect of avoiding causing noise pollution to sound.
