Problems solved by technology
Existing fresh air fans generally have low filtration efficiency, especially for the filtration of PM2.5 particulate matter, and the existing filters are easy to clog, which greatly reduces the filtration performance
In addition, due to the different temperatures in the four seasons of spring, summer, autumn and winter, t

Abstract
The invention relates to a fresh air fan for heat recovery, comprising a cabinet, wherein an independent fresh air suction area, a secondary fresh air filtering area, a fresh air discharge area, a stale air discharge area, a stale air suction air and a heat exchange area are arranged in the cabinet; a first filter used for filtering outdoor air is inlaid in the fresh air suction area; an electrostatic precipitator and a fresh air fan are inlaid in the secondary fresh air filtering area, wherein the electrostatic precipitator is used for filtering fresh air passing through the first filter again, and the fresh air fan is used for discharging the fresh air passing through the electrostatic precipitator to the fresh air discharge area; a second filter used for carrying out third level of filtering on the fresh air discharged from the fresh air fan is inlaid in the fresh air discharge area; an exhaust fan used for discharging indoor stale air to the outside is inlaid in the stale air discharge area; a plate heat exchanger used for carrying out energy exchange between the fresh air and/or the stale air is inlaid in the heat exchange area; and a fresh air bypass area is arranged between the fresh air suction area and the secondary fresh air filtering area, and a bypass valve is arranged in the fresh air bypass area. The fresh air fan is high in filtering efficiency, capable of preventing blockage, large in fresh air inlet space, good in energy saving effect and strong in universality.
Description
technical field [0001] The invention relates to the technical field of air purification, in particular to a heat recovery fresh air fan. Background technique [0002] In new buildings or existing buildings (such as residences, hotels, office buildings, shopping malls, schools, clean rooms, etc.), dust and dirty air will exist, mainly including physical hazards, chemical hazards, biological hazards and hypoxia hazards. Among them, the physical hazards mainly come from exhaust gases from power stations, factories, and automobiles, which contain a large amount of heavy metals. Chemical hazards mainly refer to formaldehyde, benzene, and toluene in the air (mainly from decoration, furniture paint and adhesives, etc.). Biological hazards mainly refer to bacteria and viruses in the air, which are the main sources of colds, flu, pneumonia, bronchitis, and skin diseases. Especially in smoggy weather, bacteria attach to dust and can survive longer and spread farther. The hazard of h...
