Domestic fresh air system for apartment

Abstract

The invention discloses a domestic fresh air system for an apartment. The domestic fresh air system comprises a fresh air inlet shell and a shutter, wherein the shutter is fixed to an inlet of the fresh air inlet shell, a filter is arranged in the fresh air inlet shell, and the bottom of the fresh air inlet shell fixedly communicates with an impurity removal component used for sweeping dust and impurities on the surface of the filter. According to the domestic fresh air system, the filter is utilized to remove impurities and filter fresh air entering an fresh air inlet to remove dust and impurities, the dust on the surface of the filter is swept down through the impurity removal component and is collected into an impurity collection box, and therefore a large amount of dust attached to thesurface of the filter is avoided to cause blockage and affect the ventilation efficiency of the fresh air inlet.

Description

technical field [0001] The invention relates to the technical field of fresh air equipment, in particular to a household fresh air system for unit houses. Background technique [0002] Fresh air is the air outside the building, or air that has not been circulated by the HVAC system before entering the building. The fresh air outlets of air-conditioning units, fresh air units and variable air volume air-conditioning units are directly connected to the external space of the building to introduce fresh air. [0003] The use of fresh air can enable you to enjoy the fresh air of nature without opening the windows, avoid the occurrence of air-conditioning diseases, supplement oxygen, eliminate the smell of heat dissipation from personnel, and the smell of indoor equipment and fixtures, effectively adjust indoor humidity and discharge bacteria and viruses. [0004] At present, the fresh air system uses mechanical air supply. The indoor air enters the return air system through the ...

AI Technical Summary

Problems solved by technology

[0004] At present, the fresh air system uses mechanical air supply. The indoor air enters the return air system through the indoor return air grille, and is discharged through the dirty air outlet, while the outdoor air enters through the fresh air inlet, and then enters the return air system for cooling or heating. And it is discharged to each room through the air intake grille. The first step to transport fresh air is to absorb fresh air from the outside. In order to prevent external impurities and dust from entering through the fresh air inlet, louvers and metal mesh covers (for shutters) are usually added outside the fresh air inlet. to prevent rain, the metal mesh cover prevents birds from entering), add a filter at the fresh air inlet to filter the incoming dust and impurities, and clean the fresh air inlet every six months. The outer metal mesh cover and shutters are easy to clean, but the internal filter The net needs to be disassembled and replaced or cleaned after the fresh air inlet, which is inconvenient to clean, and when the filter is blocked by catkin dust, the ventilation volume will be reduced, which seriously affects the use effect. Therefore, we propose a unit for house fresh air system
