Positive-pressure air-feeding fresh-air changing system

Abstract

The invention discloses a positive pressure air supplying air exchanging system that includes working host, control component, air sending pipeline. Air suction opening air filter, fan and air exits are set on working host. The control component includes main controller that connects to fan. Air sending pipeline includes plural indoor wind send opening and plural outdoor air exit. The invention has simple structure and has good air exchanging effect. It could be used in home or office.

Description

technical field [0001] The invention relates to a fresh air ventilation system, in particular to a positive pressure tissue supply fresh air ventilation system, which belongs to the technical field of indoor ventilation. Background technique [0002] Indoor air quality is directly related to human life and health. With economic development, residents pay more and more attention to the improvement of indoor air quality while paying attention to apartment structure, decoration, airtight energy saving. The circulation and replacement of indoor air is to ensure air quality. the main way. [0003] Traditional ventilation methods are: [0004] 1. Open the windows for ventilation, the air flows blindly, the air entering the room carries a lot of dust, and at the same time it brings noise pollution; it causes energy waste in houses with temperature adjustment equipment; opening the windows will also bring security problems, and there may be thieves intrusion. [0005] 2. The vent...

AI Technical Summary

Problems solved by technology

[0004] 1. Open the windows for ventilation, the air flows blindly, the air entering the room carries a lot of dust, and at the same time it brings noise pollution; it causes energy waste in houses with temperature adjustment equipment; opening the windows will also bring security problems, and there may be thieves intrusion

[0005] 2. Ventilation fan for ventilation, which is an unorganized air supply. The air entering the room flows in through the unsealed gap in the room, without filtering treatment, and entrains a large amount of dust; and the ventilation area is limited, which can only solve the local ventilation of some areas , when there is no introduction of fresh air, the exhaust effect is very poor, and the purpose of effective ventilation of the house cannot be achieved

[0006] 3. Air purifiers and negative ion generators only treat indoor air floating objects, and cannot provide fresh air rich in oxygen; and as the air pollution level increases, the treatment effect will decrease significantly, and the amount of oxygen in the air will decrease ;The air purifier can absorb some harmful substances such as dust, but cannot absorb harmful molecules in the gas

[0007] 4. The negative pressure fresh air system is actually a multi-suction ventilation fan, which cannot effectively filter the air entering the house, nor can it effectively form a reasonable flow of room air, and the pipeline layout is more complicated

The technical solution system has a small ventilation area, the indoor air cannot be fully replaced, and the ventilation effect is poor, and the system uses a single exhaust outlet, which cannot meet the requirements of multi-point air supply, and is not suitable for large-scale residences
