Ventilation type double-layer curtain wall system

Abstract

The invention relates to a ventilation type double-layer curtain wall system. The ventilation type double-layer curtain wall system comprises a light-transmitting outer wall, a ventilation inner wall and a heat transfer frame, the ventilation inner wall and the light-transmitting outer wall are oppositely installed in the heat transfer frame, the ventilation inner wall, the light-transmitting outer wall and the heat transfer frame are matched to form a containing cavity, and a communicating groove is formed in the position, connected with the light-transmitting outer wall, of the top of the heat transfer frame. The communicating groove communicates with the containing cavity and the outside, an elastic air bag is arranged at the groove bottom of the communicating groove, a communicating air gap is formed between the elastic air bag and the light-transmitting outer wall, the elastic air bag absorbs heat to expand and blocks the communicating air gap, the elastic air bag releases heat to contract and opens the communicating air gap, and green plants are planted in the containing cavity. A controllable air gap communicating the containing cavity with the indoor space is formed in the ventilation inner wall, and the width of the controllable air gap is in negative correlation with the temperature of the ventilation inner wall. The indoor and outdoor air exchange rate is regulated and controlled according to the environmental influence, and the indoor air quality is guaranteed.

Description

technical field [0001] The present application relates to the field of building curtain walls, in particular to a ventilated double-layer curtain wall system. Background technique [0002] The double-layer ventilated curtain wall appeared in Europe in the 1990s and has been gradually applied. As an emerging technology product, the good environmental protection and energy-saving performance of the double-layer ventilated curtain wall, as well as the more changes brought about by the novel structure to the exterior decoration of the building, play a great role in improving the thermal insulation, heat insulation and sound insulation functions of the curtain wall. . From an economic point of view, the unit area cost is relatively high, and the initial investment is large, which is nearly double that of traditional curtain walls. Most of the buildings using double-layer curtain walls in my country are high-rise commercial office buildings or some landmark buildings, and there a...

AI Technical Summary

Problems solved by technology

In the current office building, the central air-conditioning is usually used to supply air-conditioning in the room. Since the double-layer curtain wall is relatively closed, it is easy to form indoor high pressure.

At noon, the outdoor temperature is high and the air pressure is low. When the opening of the double-layer curtain wall is large, the indoor cold air will quickly flow out of the window, which not only makes the room heat up rapidly, but also increases the pressure on the central air conditioner, resulting in waste of electricity, and at noon. The fresh air generated by the action will flow out with the airflow and cannot be compensated for indoors

If the opening of the double-layer curtain wall is reduced, at night, the photosynthesis of plants does not proceed or is weak, and more carbon dioxide is produced. The weak airflow caused by the small opening will make the carbon dioxide not discharged in time, which will affect the indoor air quality.
