Description
Technical field
The present invention relates to a kind of air cleaner, especially relate to one and can realize indoor-outdoor air ventilation cleaning, can realize again the wall-hung ventilating clearing machine that indoor air circulation purifies simultaneously
Background technology
The factor that affects IAQ comprises indoor pollutant, outdoor pollutant and indoor carbon dioxide excessive concentration etc.Indoor pollutant has strong toxicity, long feature of duration.Outdoor pollutant because of atmosphere pollution day by day serious.Indoor carbon dioxide excessive concentration causes indoor anoxic, makes human body produce tired and irritated sense.The method that solves room air pollution comprises the ventilation of windowing, fresh air ventilator and air cleaner.
Windowing, ventilate can either be to the fresh oxygen of indoor introducing, can dilute again and the air of discharge chamber internal contamination, is not only subject to the restriction of weather and wind speed but window to ventilate, and is also subject to the restriction of outdoor air pollution thing.
The operation principle of fresh air ventilator is organized ventilation, is divided into the new blower fan of negative pressure, the new blower fan of malleation and new blower for heat recycling.The new blower fan of negative pressure is made up of blower fan, exhaust duct, exhaust outlet etc., and it is outdoor that the air of indoor dirt is discharged to by exhaust outlet and exhaust duct, and introducing from door and window gap that new wind is passive is indoor.The new blower fan of malleation is made up of blower fan, air supply duct, air outlet etc., and it is indoor that outdoor air is delivered to by air supply duct and air outlet, and what the air of indoor dirt was passive is discharged to outdoor from door and window gap.New blower for heat recycling is made up of blower fan, heat exchanger, air supply duct, exhaust duct, air outlet, exhaust outlet and filter etc., outdoor air is delivered to each room by air supply duct and air outlet, indoor foul atmosphere is by outside exhaust duct and exhaust outlet discharge chamber, and heat exchanger carries out recuperation of heat.The shortcoming of fresh air ventilator is: longer air supply duct easily accumulates dust and bacterial reproduction; Can not round-the-clockly turn round by the impact of outdoor temperature; Air supply duct and exhaust duct installation cost is high, difficulty is large, needing to destroy finishing could install.
The operation principle of air cleaner is the continuous circularly purifying of room air, is made up of blower fan, filter etc., and indoor air is exported clean air after the continuous circularly purifying of filter.The shortcoming of air cleaner is: can not stop pollutant from outdoor enter indoor; Cannot reduce the concentration of indoor CO2; Indoor oxygen content is low.
Number of patent application is in 201210037660.8 patent of invention, to disclose a kind of " the multifunctional indoor air cleaner of coupling purification and fresh-air ventilation ", this device is by the air intake ratio of air quantity configuration adjustment device conditioning chamber external air inlet and indoor circulation wind, utilize coupling purification device to air cleaning, its advantage is: forced draft purification efficiency is high, and can enter indoor by the outer pollutant of air lock; User can regulate according to outdoor temperature height the size of intake.Its shortcoming is: cleaner is to regulate resh air requirement and return air amount, complex structure by air quantity configuration adjustment device simultaneously; Resh air requirement and return air amount can not regulate alone; Only have a return air inlet and air outlet, can not efficiently utilize purifier.
Summary of the invention
