Preferably, the first window frame 1 is located below the second window frame 2, and the second window frame 2 is equipped with a Closed transition season noise reduction ventilation device 21, the transition season noise reduction ventilation device 21 includes an outer glass 211, an inner glass 212 and a sliding window 213 spaced sequentially from the outside to the inside, and the inner glass 212 and the outer glass Ventilation slits 20 are provided on the 211, the first window frame 1 is equipped with a sash, and the outer window is also equipped with an outer sunshade window 4.

Preferably, the outer glass 211 and the inner glass 212 have different thicknesses.

A mini electric fan 214 is installed in the cavity between the inner glass 212 and the outer glass 211 . The number of mini electric fans is determined according to the number of people in the room.

The thickness of the outer glass 211 is 5 mm, and the thickness of the inner glass 212 is 8 mm.

The ventilation slit 20 is in the shape of a transverse strip.

It is a very effective energy-saving measure to carry out natural ventilation under suitable weather conditions, especially in the transition season to use natural ventilation to cool down, and the noise reduction should be satisfied while cooling, and the transition season ventilation and noise reduction device 21 is installed on the second window frame 2, the transition Seasonal noise-reducing ventilation device 21 comprises outer layer glass 211, inner layer glass 212 and flat sliding window 213 which are sequentially spaced from outside to inside, ventilation slits are all set on the inner layer glass 211 and the outer layer glass 212; the outer layer glass 211 and the inner glass 212 have different thicknesses to reduce resonance effects; a mini electric fan 214 is installed in the cavity between the inner glass 212 and the outer glass 211, which can also significantly reduce outdoor noise adverse effects; when there is no sunshade requirement in the transitional season, the outer sunshade window is closed, as shown in Figure 5, the sliding window is opened, and the air is supplied by the rotation of the mini electric fan to achieve the purpose of cooling and noise reduction .

The sliding window is located inside the inner glass layer, which can ensure thermal insulation and air tightness when closed. The sliding window refers to a window equipped with a sliding hinge, which can open or close the sash parallel to the normal direction of the facade.

The transition season ventilation and noise reduction device weakens the outdoor noise through the following two designs: 1. Because the inner glass and the outer glass have some horizontal strip-shaped ventilation gaps, the opening surface is small, and the outdoor noise is weakened as much as possible while ventilating. Indoor way; 2. The electric fan has a strong vibration force during operation, and the noise transmission is realized through the vibration of the medium. The vibration force of the fan can interfere with the vibration amplitude and frequency of glass and air caused by outdoor noise, so as to Attenuates the noise transmitted to the room.

The upper bright part 31 is an inverted window. The sash of the first window frame 1 is a fixed window 11 .

There is no sun-shading facility on the outside of the upper beam 31, and the outer sun-shading window 4 can be selected as a shutter, a roller shutter or a roller shutter window. When the outer sun-shading window is opened in summer, most of the solar radiation heat is isolated, and at the same time, the upper beam can still transmit light. , so as to ensure the basic natural lighting requirements in the room. Optimally, as shown in FIG. 3 , the black lines with arrows represent the direct sunlight. After the outer window is installed, it should be ensured that the direct sunlight does not enter the room through the upper light 31. The height size of the upper photon is determined by two factors: the shadow occlusion of the surrounding environment and the local sun altitude angle. There are two types of sunlight, direct and diffuse, and glare is usually caused by direct light. In order to avoid the possibility of glare indoors caused by brightening, it should be ensured that the direct sunlight in summer cannot reach the indoor working surface. Taking the Beijing area as an example, the summer air-conditioning cooling period is about May 15 to September 15 every year, and the lowest solar altitude angle is about 50 degrees on September 15. The height of the upper transom should be designed to ensure that when α is at an angle of 50 degrees, the direct rays of the sun cannot directly enter the room.

Preferably, the upper transom 31 is an inverted window. As shown in Figure 4, the tilt-in window can be opened inwardly at night in summer, and at the same time of ventilation, because the size of the tilt-inward opening is small, it can take into account the anti-theft. The control method can be designed as electric opening, controlled by group control, and unified management by the building administrator at night. Schools and office buildings are mostly vacant at night. At this time, there is no requirement for noise isolation or smog prevention. At night, the inverted windows can be opened to make full use of the temperature difference between day and night, and achieve cooling and cooling effects through natural ventilation. Natural ventilation at night can significantly reduce the temperature of the building structure and indoor air, especially by making full use of the cold storage capacity of the building structure, it can slowly absorb the heat in the room in the morning on weekdays and reduce the use time of air conditioners in the morning, thereby achieving the effect of energy saving.
