Description
Technical Field
The invention belongs to the technical field of sound insulation, and relates to a noise reduction window.
Background
At present, urban traffic is more and more convenient, and private cars are more and more, so that a lot of buildings are troubled by traffic noise, especially high-rise buildings facing the city-around roads. In noisy environments, occupants typically use windows to reduce noise. However, human metabolism produces carbon dioxide and other gases, and ventilation is required to supplement oxygen and dilute residual heat, humidity or harmful gases in the room.
Sound is a mechanical wave that propagates into the room through vents, seams or holes, and noise reduction and ventilation are generally difficult to achieve simultaneously. Some residents can install a fresh air system indoors, but initial investment and operating cost are increased. In addition, fan noise is also introduced by the fresh air system.
The current window opening mode comprises a sliding window, a casement window and an upper and lower suspension window. Among these modes, the casement window is preferable in terms of sealing performance and ventilation. The flat-open window is opened to left and right sides more, perhaps opens downwards, and traffic noise can pass through the opening with direct sound mode and get into indoorly, and a plurality of noise sources can superpose at the opening part even, increase indoor noise puzzlement.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The noise reduction window comprises a fixed window 10, wherein a fresh air window 4 and an air exchange window 5 are arranged on the fixed window 10, a rain shield 1 is fixedly connected to a wall body above the fixed window 10, the rain shield 1 is located right above the fresh air window 4, and the rain shield 1 is provided with a sound insulation baffle 8 as shown in figures 1, 2, 3 and 4. The fresh air window 4 and the ventilation window 5 are opened upwards, the fresh air window 4, the ventilation window 5 and the fixed window 10 are connected through hinges 3, and the hinges 3 are embedded hinges. Sealing gaskets 2 are respectively arranged between the side wall of the fresh air window 4 and the fixed window 10 and between the side wall of the ventilation window 5 and the fixed window 10, the sealing gaskets 2 are fan-shaped, and the sealing gaskets 2 can be folded. Fresh air window 4 and ventilation window 5's inboard all is provided with handle 6, baffle 8 is perpendicular mutually with weather shield 1, baffle 8's bottom rigid coupling has prevents diffraction groove 9, prevents that diffraction groove 9 is the U type, baffle 8 has two, between two baffle 8, prevent that the equal rigid coupling in diffraction groove 9 has acoustic absorbent 11, acoustic absorbent 11 adopts the cotton wedge of melamine, baffle 8 keeps away from one side rigid coupling of weather shield 1 has outer baffle 7.
According to the noise reduction window, when a large amount of air exchange is needed in daily use, the air exchange window is opened by rotating the embedded hinge through the handle, and quick air exchange is completed. When a small amount of ventilation is needed, the ventilation window is closed, the fresh air window is opened by rotating the embedded hinge through the fresh air window handle, and the blocking of sound wave diffraction is completed by unfolding the folded fan-shaped sealing gasket.
To sound insulation weather shield, wherein weather shield and outer baffle accomplish main support and rain-proof effect, the sound absorbing member has been embedded to sound insulation baffle, and the reinforcing is to stopping of dead ahead noise. And for the U-shaped anti-diffraction groove, the transmission of rain and noise can be effectively realized when the groove depth exceeds 10cm, and the part is simulated
Wherein, fan-shaped sealed pad is installed in the both sides of opening the back window, can effectual reduction noise diffraction get into indoorly to owing to there is the weather shield, and the weather shield outside is posted and is had sound insulation material, owing to the existence in sound shadow district, make the window glass of opening play the purpose of reflected noise, and the opening is towards the position of no noise source, for example sky, this kind of mode of windowing can very big degree more
The noise reduction window has the use principle that the window is divided into a fixed window and an openable window, and the openable window is divided into a fresh air window and a quick ventilation window.
The noise source orientation is analyzed and the window is windowed away from the noise source so that the open window glass serves the purpose of reflecting noise, while the opening is oriented towards the noise source-free orientation, such as the sky.
The two sides of the opened window and the window frame are sealed in a fan shape, so that sound waves are prevented from being diffracted into the room.
The specially-made sound insulation baffle is placed right in front of the new fresh air window, and the sound can be blocked at the corners of the groove and the board surface by the effective structure.
The window opening area of the fresh air window is determined by the fresh air quantity required by indoor personnel. According to GB50736-2012 design Specification for heating, ventilating and air-conditioning of civil buildings 3.0.6, the minimum fresh air quantity required by each person is 30 m3V (h, human)]. Suppose that indoor personnel are n standard people, indoor fresh air volume is:
because the wind pressure is unstable, only the hot pressing effect is considered during the design of the natural ventilation. The hot-pressing ventilation is a density difference caused by the temperature difference of outdoor air, so that the pressure difference is generated to form a phenomenon that hot air flows upwards and cold air flows downwards. The indoor fresh air volume is equal to the hot-pressing ventilation volume of the fresh air window, namely:
in the formula: mu-flow coefficient, about 0.6-0.62;
a-fresh air window opening area, m2；
Delta p is the pressure difference between the inside and the outside of the new air window, Pa;
rho-density of fluid flowing in new air window, and average density of internal and external air flow kg/m3。
The window opening area of the new fresh air window is as follows:
A＝l·h
in the formula: l is the length of the opening area of the new air window, m;
h is the height of the opening area of the new air window, m.
The difference of the internal and external pressure of the new air window is as follows:
Δp＝g(ρo-ρi)h
in the formula: g-acceleration of gravity, m/s2；
ρoDensity of outdoor air, kg/m3；
ρ1Indoor air density, kg/m3；
h is the height of the opening area of the new air window, m.
Substituting formulas (4) and (3) into formula (2) to obtain the windowing area size of the new fresh air window:
the windowing area length l and the height h of the fresh air window satisfy the formula (5). Taking the winter in Xian city as an example, suppose that 2 standard persons exist indoors and the room is indoorTemperature ti22 ℃ and a density of 1.196kg/m3(ii) a Outdoor temperature to2.3 ℃ and a density of 1.285kg/m3. The result of the calculation according to equation (5) is: l2h3＝0.000549m5. If the length of the new air window is l 0.6m, the windowing height is 0.115m, and the area of the windowing A is 0.069m2。
Taking the summer season of the city of western-ann as an example, only night time ventilation is considered (because night time people are sensitive to noise versus day time). Suppose there are 2 standard persons in a room, the indoor temperature tiAt 27 deg.C, density 1.175kg/m3(ii) a Night outdoor temperature t o23 ℃ and a density of 1.195kg/m3. The result of the calculation according to equation (5) is: l2h3＝0.0023m5. If the length of the new air window is l 0.6m, the windowing height is 0.186m, and the area of the windowing A is 0.112m2。
The noise reduction window solves the problem of high indoor noise in the prior art. In a room close to a street, the influence of traffic noise on people in a building can be reduced to a certain extent, and the daily ventilation requirement in the room is met.
