an indoor ventilation system

[technical field]

The utility model relates to a ventilation system, in particular to an indoor ventilation system.

[Background technique]

With the development of the economy and the improvement of people's living standards, air conditioners, as an important household appliance, play an increasingly important role in national economic production and people's social life.

The emergence of air-conditioning enables people to actively control the living environment, instead of passively adapting to nature as before; the extensive use of air-conditioning makes people gradually downplay the application of natural ventilation. Today, with the popularization of air-conditioning technology, under the dual pressure of saving energy and maintaining good indoor air quality, scientists around the world have to re-examine the traditional technology of natural ventilation. In this context, it is more important than ever to introduce natural ventilation, a traditional architectural ecological technology, into modern buildings: natural ventilation can not only effectively cool down the indoor environment, but also save conventional energy, reduce Environmental pollution, but also can greatly improve the quality of the indoor environment.

Natural ventilation refers to the ventilation that uses heat pressure caused by air density difference or wind pressure caused by wind force to promote air flow. This is a traditional building heat protection technology, which has been widely used in traditional houses all over the world. In hot and humid areas, traditional dwellings often have such appearances: the buildings have wide windows; light walls; far-reaching overhangs; high ceilings with vents; Hot air, collecting more cool wind... Behind this image, there is a simple concept of the working people on the use of natural ventilation technology. Natural ventilation is a ventilation method with great potential, and it is a primitive means that human beings have relied on for a long time to adjust the indoor environment.

The traditional natural ventilation device uses the heat pressure caused by the density difference of the air or the wind pressure caused by the wind to promote the air flow and carry out ventilation, but the traditional natural ventilation will have certain problems: first, when the indoor and outdoor air density, That is, when the temperature is equal, the indoor and outdoor air cannot circulate, causing the indoor air to be turbid; the second is when the number of people in the room increases sharply in a short period of time, or when the room needs to be quickly ventilated due to sudden accidents. The traditional natural ventilation device is a passive way of exchanging air, which cannot actively meet people's needs, and affects people's quality of life to a certain extent.

The utility model with the patent number CN201320732774.4 discloses a solar ventilating cap, which includes an outer cap, an outer brim, an inner cap, an inner brim, a solar panel, a wire, a battery, a booster fan, a net Shaped air inlet, air guide channel, hole-shaped air outlet, ring-shaped air outlet, support device. The utility model can improve the indoor ventilation quality, but the utility model has a large air duct resistance and poor ventilation quality.
