Description

Multifunctional Mechanical Ventilation Soundproof Windows

technical field

The utility model relates to a multifunctional mechanical ventilation and sound insulation window, which is especially suitable for ventilation, lighting and sound insulation of buildings in places with relatively high environmental noise, and belongs to the field of noise control and treatment and improvement of indoor environment.

Background technique

In recent years, traffic noise (including road, aviation and shipping noise) pollution has become increasingly serious. In order to improve the indoor acoustic environment, sound insulation window technology has been widely used. The main measure of ordinary soundproof windows is to use multi-layer laminated (or laminated) glass or insulating glass instead of ordinary single-layer glass, and use plastic steel or aluminum alloy profiles with better sealing performance as window frames. Although ordinary sound-proof windows can effectively reduce indoor noise, because the windows do not have the function of ventilation, the indoor air quality is difficult to meet the standards of healthy housing, which affects people's physical and mental health. In order to achieve the purpose of ventilation, the window can only be opened, and the sound insulation effect of the window is completely lost at this time. To solve this problem, there are a number of patents for ventilation and sound insulation products, which mainly adopt special designs to achieve natural ventilation, or use fans for mechanical ventilation to achieve ventilation without opening windows.

Among them, the various patents relying on natural ventilation for ventilation basically allow the airflow to pass through the anechoic passage of specially designed sound-absorbing materials or sound-absorbing structures inside, so that the outdoor noise is greatly attenuated when passing through the anechoic passage, but this The muffler channel generally has a large resistance coefficient (pressure loss) to the airflow. In some patents, in order to reduce the resistance coefficient of the air flow channel, the channel is designed to be very short, and the resistance coefficient (pressure loss) is greatly reduced, but at this time the noise reduction of the air flow channel is also greatly reduced, making the sound insulation window The sound insulation performance is significantly reduced. At the same time, natural ventilation and sound insulation windows will have better ventilation effect only when there is wind outside or reaches a certain wind force, and the ventilation volume will change with the external environment. Generally speaking, it is difficult for natural ventilation sound insulation window products to have good ventilation and sound insulation performance at the same time.

Other patents rely on additionally installed blowers for mechanical ventilation, i.e. mechanically ventilated acoustic windows. The utility model patent No. 02233682.6 sets the two sides of the window as ventilation channels, and a layer of sound-absorbing layer is provided in the channel. The fan is installed at the air outlet. Since the fan is installed on the indoor side, the noise of the fan itself is directly discharged into the room without being silenced by the anechoic channel. During operation, the room is greatly affected by the noise of the fan. The utility model patent with the patent number of 200320119754.6 realizes indoor exhaust to the outside through the exhaust fan installed on the outside of the window with double-layer sound insulation glass and the labyrinth air duct connected with the room. The additional installed fan and its The ventilation channel protrudes from the outer wall, affecting the landscape of the building's facade. The utility model patent with the patent number 03272915.4 designs the window as a bay window (protruding from the outer wall), and the lower part of the bay window is a natural ventilation area, and the ventilation is realized through the louvers on both sides of the window and the short S-shaped noise reduction channel; The upper part is the active ventilation area, which adopts axial flow fan to force the air in. Due to the short air inlet channel and low noise reduction, the sound insulation performance of the sound insulation windows including the noise reduction channel is significantly reduced. The utility model patent No. 03276640.8 is provided with a horizontal narrow and long sound-absorbing ventilation channel on the top of the sound-proof window, and the axial flow fan installed at the outdoor side air outlet is used to force the air into the room. The utility model patent with the patent number of 200720127633.4 has an air duct on both sides of the soundproof window, the air duct on one side exhausts the air from the indoor to the outdoor through the exhaust fan, and the air duct on the other side enters the air from the outdoor to the indoor , That is, the wind is taken in from the air duct on one side of the window, and the air is discharged from the other side of the air duct, and it is equipped with electric control, solar energy and sterilizing and filtering devices. The structure is relatively complicated, but it is inconvenient to maintain. Due to the resistance coefficient (pressure loss) of the air flow channel, axial flow fans are commonly used in the above patents. Axial flow fans are more sensitive to the resistance coefficient, that is, the air duct resistance coefficient will significantly reduce the actual ventilation volume of the fan. If the air volume of the fan is increased, the fan will Energy consumption and noise will increase. At the same time, the above patented products do not have auxiliary functions such as negative ion generation and ice cooling.
