Convection type air purifying exchanging method and its exchanger

Abstract

The invention relates to draft and ventilation technique, concretely a convection type air purification exchange buffering method and its exchanger. In accordance with the program designed, fresh air outside which is disposed is brought in by main engine and brought out by auxiliary engine. The fresh air outside whose dust is filtered by filtering net, and becomes clean through the disposal of disinfection and sterilization, humidification and negative ion. The main engine and auxiliary engine are included in the exchanger, a motor with impeller on its rotating shaft is installed with air passage engine between the main engine and auxiliary engine and its rotating shaft is paralleled with axial line of the air passage engine. The device can bring fresh air disposed in room, meanwhile bring smoke, dust and harmful gas out, especially the automatic clearing function added of the filtering net has decreased people's anxiety.

Description

technical field [0001] The invention relates to ventilation technology, in particular to a convective air purification and exchange method and a switch. Background technique [0002] In the prior art, there are mainly the following ways to purify and exchange indoor air: using a simple ventilating fan to exhaust; using an air purifier to exchange; using an air conditioner to exchange and using a central air conditioner to exchange. Each of these methods has advantages and disadvantages. [0003] Among them, when the ventilation fan exhausts, the room is in a closed state, just like pumping air in a bottle with only one mouth. At this time, the bottle is in a negative pressure state, there is no air intake, and the airflow cannot form a convection state, so the exhaust is basically ineffective. The smoke and dust in the room cannot be discharged. Air supply works just the opposite, making it difficult to get fresh air into the room. [0004] The filter screen of the air pu...

Problems solved by technology

The ventilation system is mainly relying on two very thin long pipes for ventilation and exhaust. Some experts have reported that the effect is not as great as that of the gaps in the doors and windows.

[0006] There is a big disadvantage of central air conditioners, that is, the ventilation ducts. During use, the dust, bacteria, and mold in the ventilation ducts cannot be removed.
