The natural ventilation sound insulation window has the main ventilation function of hot-pressing ventilation, and the ventilation power of the natural ventilation sound insulation window depends on air density difference and height difference of an air inlet and an air outlet caused by indoor and outdoor air temperature difference. The air outlet at the inner end is arranged in the deep part of the room, and the air inlet is arranged near the window, so that the air temperature difference at the air inlet and the air outlet can be effectively increased to the maximum temperature difference between the indoor part and the outdoor part.
The specific ventilation principle is as follows:
(1) the natural ventilation sound insulation window has the main ventilation function of hot-pressing ventilation, and the ventilation power of the natural ventilation sound insulation window depends on air density difference and height difference of an air inlet and an air outlet caused by indoor and outdoor air temperature difference. When the indoor temperature is higher than the outdoor temperature, the outdoor air flows into the room through the air inlet at the lower part of the natural ventilation sound insulation window due to the heavier air, and the lighter indoor air is discharged from the air outlet at the upper part. According to the standard gas equation, the temperature and the volume are in direct proportion under the condition that the pressure of the gas with equal mass is constant, and therefore, the temperature and the density are in inverse proportion under the condition that the pressure of the gas with equal mass is constant. Therefore, the calculation formula of the hot-pressing ventilation power is as follows:
(2) The natural ventilation sound insulation window structure is formed by combining glass and a ventilation pipeline, and has good sound insulation performance. The area of the ventilation sound insulation window is assumed to be 3m2The areas of the air inlet and the air outlet are respectively 0.125m2The sound insulation quantity of common window glass is respectively 25dB, 30dB and 35dB, and the insertion loss of a pipeline is respectively 10dB, 15dB and 20 dB.
Then, according to the combined sound insulation theory, only the transmission loss needs to be obtained, the transmission loss can be obtained through the acoustic energy transmission coefficient tau of the window, and the transmission coefficients of the glass and the ventilation pipeline can be obtained according to the formula (2).
The acoustic energy transmission coefficient of the combined sound insulation can be calculated by the equation (3) as the average acoustic energy transmission of the glass and the pipeCoefficient is obtained in the formula
Is as follows
The sound energy transmission coefficient of the sound insulation member,
is as follows
The area occupied by the sound insulation component is increased,
is the total area of the sound-insulating window. The sound insulation data are shown in table 1, and one of the combined sound insulation data is selected and converted into sound insulation quantity of each frequency to compare the sound insulation quantity of the natural ventilation sound insulation window with or without the pipeline, as shown in table 1.
TABLE 1 Natural ventilation and sound insulation Window combination sound insulation amount with or without ventilation duct
