Fresh air purification system in full replacement mode

Abstract

The invention discloses a fresh air purification system in a full replacement mode. The fresh air purification system in the full replacement mode has the multiple functions of primary-efficiency filtration, organic substance decomposition with photocatalyst, medium-efficiency filtration, high-efficiency electrostatic dust collection, ozone decomposition, total heat exchange and the like, is capable of effectively removing 2.5 [mu]m or below fine particles in air and has the functions of sterilization, decomposition of formaldehyde, methylamine, benzene, xylene, TVOC, harmful organic substances and excessive ozone in the air and total heat exchange at the same time, so that fresh air fed into a room is comprehensively purified, and the cold (hot) quantity of the indoor air is recycled.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a fresh air purification system in a full replacement mode, which is suitable for various residential buildings, offices, office buildings and other buildings, especially for areas with serious air pollution. Background technique [0002] Air pollution and the deterioration of the atmospheric environment have become an important factor affecting human health. In the case of outdoor haze weather, because the windows cannot be opened, indoor pollutants and bacteria continue to accumulate, giving birth to various diseases; insufficient oxygen makes people Dizziness, these seriously affect people's health, and it is imminent to improve the indoor air quality of the home. Existing traditional purifiers only process and purify the original indoor air without introducing outdoor fresh air, resulting in insufficient oxygen content and poor comfort. The fresh...

Problems solved by technology

[0003] The fresh air in traditional residences mostly adopts the supply method of upward supply and upward return, that is, the supply and exhaust air ducts are laid along the top of the room, which will greatly reduce the aesthetics of the interior, increase the decoration cost, and affect the indoor ventilation effect, because most of them come from The fresh air sent in from the upper part of the room is exhausted by the upper exhaust duct before it reaches the lower part of the human activity area.

Generally, the air volume of the fresh air supply for residential buildings is very small, about 60m for each bedroom 3 / h, if the air supply and exhaust method is adopted, the effective fresh air supply will be very small, and the personnel activity area in the room will not receive effective purification and oxygen supply
