Description

ventilation system

technical field

The invention relates to the field of air exchange, in particular to a ventilation system.

Background technique

In recent years, air pollution has become more and more serious, and the country has continuously taken measures to reduce pollution. However, pollution has continued to intensify recently, and the air quality is getting worse and worse. Toxic smog occurs frequently, and the weather forecast also broadcasts poor air quality every now and then.

The increasing sales of masks, air purifiers and other products show that people have realized the poisonous effect of air pollution. At the same time, when using an air purifier at home, it needs to be completely closed indoors to be effective, but there is a great hidden danger in a completely closed indoor state, that is, the indoor air cannot be renewed, and the long-term use of the purifier will cause secondary pollution, which is impossible at all. Keep purifying indoor air for a long time, and the purifying effect of formaldehyde on the existing air purifiers on the market is also uneven. In addition, with the improvement of people's quality of life, the proportion of house decoration is also increasing. If the windows of the newly renovated house are closed, harmful gases such as formaldehyde and benzene will be released continuously, and the density will increase, causing serious pollution to the air. , but also a serious threat to people's health.

Due to the worrying air quality in most cities in my country, installing a filtration ventilation system indoors is an effective means to improve indoor air quality. At present, the main ventilation systems on the market have certain shortcomings, and there are mainly the following four working modes:

2. The induced draft fan draws air to the outside, and the room forms a negative pressure state, and fresh air is sucked into the room from the vents or gaps. Disadvantages: the air enters the room without filtering, and it is only changed, which is not clean.

3. Equipped with the combined operation mode of blower and induced draft fan. The blower and induced draft fan work at the same time. Disadvantages: fast air renewal leads to large temperature changes, which has a great impact on indoor temperature. The phenomenon of convection.

4. The existing relatively mature ducted fresh air system in the prior art has heat exchange and air intake and air supply systems. Disadvantages: the net height of the general building is 2.4-2.6m, while the ducted fresh air system needs to be walked on the roof Ducts and fans are not suitable for installation due to the low net height of the floor.
