Now many consumers are confused about whether to install fresh air system and what the practical significance of installing fresh air system is. The satisfaction rate of all fresh air system users is 100%. Since the customer satisfaction rate is so high, all say that the fresh air system is good, so what is the good thing?
A, home hygiene is easy, cleaning is no longer frequent, the windowsill and furniture in the home can be cleaned once in ten days or eight days, why? The original professional detection, under normal circumstances indoor air pressure is negative pressure (weak positive pressure), outdoor air pressure is positive pressure, outdoor air pressure is higher than indoor air pressure, so outdoor air in the indoor circulation. Because of the serious pollution now, there is a lot of dust and smoke in the air, resulting in dust pollution of indoor furniture, floors and windowsills. The filtered fresh air is blown from the outside to the inside through the fresh air system. A room with closed doors and Windows is like a closed container. Due to continuous air supply, indoor air pressure will be higher than outdoor air, indoor air will overflow, unable to fight against outside air pollution, so our indoor is not easy to be polluted, so we do not often do sanitation. This advanced concept is widely used in industrial clean rooms, asepsis rooms and other places.
Two, the indoor air is fresh. This is easy to understand. The fresh air system has three layers of filtration. After the adsorption of the internationally leading nuclear activated carbon independently developed and produced by The China Radiation Institute, the fresh air with pollution-free and efficient filtration above PM2.5 can be continuously sent into the room. China radiation fresh air system is the first product in China with purification efficiency of more than 99% in open environment. Coupled with a large number of negative oxygen ions produced by the negative ion generator, the indoor air after rain will have a fresh feeling of forest air oxygen bar.
Three, sleep soundly at night, wake up in the morning willing to get up. After detection, outdoor air oxygen content is about 19%-21%, indoor air oxygen content in 17% or so below. Because most people sleep with the Windows closed and the curtains drawn at night, breathing in this relatively closed environment deplets oxygen overnight. General morning indoor air oxygen content in 12-15% or so, basic hypoxia. According to statistics, an adult breathes in about 6.5 liters of air per minute at rest, requiring nearly 10,000 liters of air per day. The normal oxygen content in the air is about 19-21%. When there is not enough oxygen, a person will suffocate. When the oxygen content is between 12% and 15%, people will have shortness of breath, headache, dizziness, fatigue, weakness and slow movement; When oxygen levels are between 10 and 12 percent, nausea, vomiting, immobility, and even paralysis occur. At 6-8% oxygen levels, people faint and lose consciousness. When oxygen levels fall below 6%, death occurs within 6-8 minutes; When oxygen levels are between 2% and 3%, death occurs instantly within 45 seconds. Indoor air has roughly the same oxygen content as outdoor air at any given time, as fresh air is constantly pumped indoors by a fresh air system. In this oxygen-rich environment, the body's cells will not be deprived of oxygen and will naturally sleep soundly. Wake up with a clear head and get up in the morning.
Four, sleeping at night because of the use of a new fan, there is no need to open the window ventilation, so the indoor environment will be relatively closed, there will be more water in the air. In 2003, the national standard for relative humidity of indoor air was promulgated and implemented. Summer cooling relative humidity should be in 40%-80%, winter heating should be controlled in 30%-60%. Suitable indoor humidity, 45%-50% for the elderly and children, 40%-50% for patients with asthma and other respiratory diseases. According to this standard, the indoor relative humidity is 30% - 60%, after using the fresh air system is basically in this range. Because indoor relative humidity is more appropriate than not using the fresh air system, coupled with the indoor oxygen-rich environment, body cells do not have hypoxia, and there is no need to open the mouth to increase oxygen intake, naturally at night the mouth will not dry.
