“Fresh air” means fresh air. As the name suggests, the “fresh air system” is the building’s mechanical and electrical system that provides fresh air to the living room (building). It is composed of a fresh air fan (or the owner of the machine, including air It consists of three parts: processing function), ventilation ducts, and air outlets (air inlet and return air). It discharges indoor dirty air to the outdoors after heat recovery (energy saving). At the same time, the fresh outdoor air enters the high-efficiency heat recovery device after being filtered and processed, and then is continuously and evenly sent into the room.
The high-efficiency filter level of the fresh air system can reach H13, and the purification efficiency is as high as 99.95%, but The purification efficiency is directly proportional to the service life of the filter. If the filter element is not replaced regularly, the purification efficiency will be reduced. The fresh air high-efficiency filter material currently independently developed and produced is the core filter material of the fresh air filter. Fresh air high-efficiency filter material is a microporous film made by special processing techniques such as calendering, extrusion, and biaxial stretching. This kind of membrane has excellent breathability, corrosion resistance, aging resistance, temperature resistance and other properties. Three-dimensional mesh structure, no through holes. The porosity and pore size distribution are important indicators to measure the film. The porosity of the film is generally between 80% and 95%. A high porosity will increase the ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
Fresh air high-efficiency filter materialThe porosity can reach more than 88%, or even higher, and this membrane has a It has 1.4 billion micropores with a pore diameter ranging from 0.1um to 0.5um. It has high and low temperature resistance (-200℃-260℃). It will not age, split, discolor, and has strong weather resistance after long-term use. At the same time, it has greater flux.
