Problems solved by technology

Now there are some products on the market, such as air conditioners and air purifiers, which all use mechanical ventilation, which inevitably produces noise, and usually consumes a lot of power, which is not considered energy-saving and environmentally friendly. Therefore, designing a device can solve the problem. Ventilation, noise reduction, light avoidance and no energy consumption will make our lives healthier and the environment more comfortable, which is the key research topic of our company

Embodiment 1

[0039] Such as Figure 1 to Figure 4 As shown, the method for noise reduction, light avoidance and natural ventilation for buildings includes the following steps:

[0040] (1) Calculate the ventilation rate according to the nature and area of ​​the building;

[0041] (II) Measure the maximum value of noise received indoors and the sound spectrum from the outside under the condition of maintaining sufficient ventilation; in order to effectively obtain the maximum value of environmental noise, the time limit for determining the maximum value of noise is at least 300 days;

[0042] (III) Use a noise reduction device capable of natural ventilation to reduce the noise value received by the room to the standard value or below;

[0043](IV) Determine the installation position of the noise reduction device on the inner and outer walls, door frames, and window frames of the building according to the indoor layout of the building and the main activity area of ​​indoor personnel. In ord...

Embodiment 2

[0054] Such as Figure 5 with Image 6 As shown, the difference between this embodiment and Embodiment 1 is that the structure of the noise reduction device adopted in the step (III) is different, and its specific structure is as follows: the noise reduction device includes a channel body fixedly connected with the building 1. The inner channel 2 is set in the channel body to connect the building space on both sides, the convex part 20 is set on the inner wall of one side of the inner channel, and the concave part matching the convex part is set on the inner wall of the other side of the inner channel 21, and several baffles 22 with bent parts arranged between the convex part and the concave part, wherein one side of the baffle body is matched with the convex part, and the other side is matched with the concave part. A corresponding number of parallel flow passages are formed between the baffle fluid and the convex part, the baffle fluid and the concave part, and the ventilat...

Embodiment 3

[0057] Such as Figure 7 with Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the structure of the noise reduction device adopted in the step (III) is different, and its specific structure is as follows: the noise reduction device includes a channel body fixedly connected with the building 1. Two inner passages 2 arranged in the passage body to connect the building space on both sides, wherein the two inner passages are Z-shaped and symmetrically arranged around the edge of the air outlet, and the two air outlets Merge into a total air outlet with this, the ventilation total amount of two inner passages matches with the natural ventilation rate that step (1) gains. The resulting installation space is thinner and larger, which is more suitable for non-load-bearing walls next to windows.

[0058] In a further design, in order to prevent the incoming air from interfering with each other, the channel body at the inner middle of the total air o...

Abstract

The invention discloses a method for noise reduction, light shading and natural ventilation for a building. The method comprises the steps that (1) the ventilation amount is calculated according to the property and area of the building; (2) under the condition that the sufficient ventilation amount is kept, the maximum value and sound spectrum of noise, from the outdoor space, received by the indoor space are measured; (3) the value of the noise received by the indoor space is decreased to the standard value or below by adopting noise-elimination devices capable of conducting natural ventilation; and (4) the mounting positions of the noise-elimination devices on inner and outer walls, door frames and window frames of the building are determined according to the building indoor layout and amain activity area of indoor personnel. Special noise reduction design is conducted by combining the specific layout and position of the building, noise reduction is achieved by utilizing the principle of the noise-elimination devices, light shading is achieved by utilizing a small wind resistance bending mode, ventilation is achieved by utilizing the natural wind pressure and indoor people or mechanical disturbance, comprehensive layout is conducted through building characteristic, the purposes of natural ventilation, light shading, noise reduction and working and life condition improving are achieved, 24-hour uninterrupted starting can be achieved, and the situations such as the indoor odor are relieved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for reducing noise and avoiding light and natural ventilation of buildings. Background technique [0002] At present, there is a serious problem that cannot be avoided in high-rise buildings and buildings facing the street - noise, which is a big problem that plagues our life and work. In cities, near streets with heavy traffic, aircraft and ship waterways, around parks and squares, beside fast-flowing rivers, during heavy rain and lightning, etc., noise seriously affects our work and life. In addition to being patient, people will take some corresponding measures: such as closing the windows tightly. If you want to avoid the deterioration of indoor sanitary conditions caused by closing the windows, you must increase mechanical ventilation. Because the motor will eventually generate noise, installation requires distribution lines, switches, and records at any time when you go...
