Air purifiers and fresh air system is essentially the difference is: 1. Air Purifier works by filtration and adsorption, which is used for charcoal, activated carbon has a saturation, after reaching saturation can no longer absorb the harmful substances. 2. The air purifier is an indoor air circulation, and the new system is the indoor air with outdoor air circulation; like air purifier is tub with water or the original, and the new air system is a shower. So, be sure to say, in terms of air purifier air purifier thoroughness, effectiveness, sustainability, are not, and fresh air system, but can not replace the air system. However, in view of its easy to move, it is suitable as a supplement and complementary tools to temporary use, if long-term residents of the home from the point of view, or a new air system to purify the air more efficiently, more thorough, more long-term, but also more economical. Based on the above analysis, we can conclude that: air purifiers over, but a new ventilation system in its ability to deal with indoor air, it can not replace the air system, just add ductless air system of the new wind model, in order to truly solve indoor air pollution problem, the preferred air system. Panasonic's new air system of choice for your new air system. The new air system Installation Considerations: The new air system host installation 1) According to the new air system dimensions, making ventilation host fixed frame; 2) will host horizontally mounted on the housing top surface, as close as possible to connect the suction outlet of the halls and rooms; 3) ventilation When the host and the cage, the middle block with rubber shock for shock treatment; 4) in the vicinity of the ventilation host installation location should be sufficient space to facilitate repair and maintenance; new wind when home-host installation in the ceiling, and its vicinity 450 × 450 should be left in a manhole, manhole reserve position should be easy to repair, top unobstructed; 5) A ventilation host motor power, voltage, configurable power cord. The power supply should be independent wenshang no pipeline of new wind, the wiring should be correct, no strong pipeline of new wind, and have a good grounding; power lines should be insulated well Jining no pipeline of new wind, not bare, exposed; the host should have a separate ventilation control device; 6) When the duct using UPVC pipe, using the air hose connection, the hose length of no more than 60cm; 7) the exhaust pipe using the hose must not be longer than 5M, more than 5M should adopt UPVC duct. Ductless air brand new, wenshang no pipeline of new wind, Hirono Environmental Engineering (View) provided by the Shandong Environmental Engineering Co. Hirono.
