The new air system was first used in public places such as hotels and office buildings.It was used as a ventilation device,and basically had no haze filtering function.This has caused many people's misunderstandings:I feel that the new wind is a system for indoor and outdoor air exchange.
But!The home fresh air system is equipped with a filter screen,and the fresh air without filter function can only be considered a large“ventilating fan”.
The fresh air system is a set of independent air treatment system composed of an air supply system and an air exhaust system.It will send fresh air to the enclosed room through the pipeline equipment,and then will form in the interior during the process of exhausting the exhaust gas from the other side to the outside from the dedicated equipment.""Fresh air flow field"to meet the needs of indoor fresh air ventilation.The fresh air has realized indoor and outdoor air circulation through the introduction of outdoor fresh air,effectively improving the problems caused by poor ventilation such as"air conditioning disease"and indoor humidity.
The fresh air filtration is achieved by an independent air treatment system consisting of an air ventilator and filter media,which filters,purifies and then delivers the outdoor fresh air to the interior.A good fresh air system can achieve a filtration rate of more than 90%for PM2.5(PM2.5 refers to particles with a diameter of≤2.5μm in the atmosphere and haze in the weather)and can control indoor PM2.5 concentration.15μg/m3 or less.
