Indoor ventilation solutions Many people ignore "ventilation" in home decoration, Feng Shui, Feng Shui. What people call Feng Shui is wind and water! Did you know? Each person needs 30 cubic meters of fresh air every hour to provide himself with oxygen. What is this concept? If your bedroom is 20 square meters, the room is about 3 meters high, and there are two people living in the bedroom, then this room can only provide you with sufficient oxygen for 1 hour! After 1 hour, the oxygen content in the air will drop significantly, and the carbon dioxide concentration will rise linearly. Over time, it becomes easy to become deprived of oxygen! If you wake up in the morning and feel groggy, weak in your limbs, and dry in your mouth, then you are hypoxic. Do you know where the car exhaust goes? Car exhaust is suspended in the air. If it is a high-rise building, the layer between the 7th and 12th floors is the air layer where car exhaust is suspended! In other words, if you live on the 7th to 12th floor, congratulations, you can breathe the freshest and purest original car exhaust every day when you open the window! Ensure indoor air circulation for a long time, and can take indoor second-hand smoke, formaldehyde, etc. out of the room! 1) Current status of indoor air quality. First pollution: soot pollution. Second pollution: photochemical pollution. Third pollution: indoor air pollution. According to research by American experts, indoor air pollution is 2-5 times more serious than outdoor air pollution. Under special circumstances, it can even reach 100 times. More than 500 volatile organic compounds can be detected in indoor air. The concentration of some harmful gases can be 10 times or even dozens of times higher than that outdoors. More than 20 of them are carcinogens. Research by the Canadian Environmental Health Organization found that 68% of human diseases are caused by indoor air pollution....2) Indoor air quality (IAQ) As early as the late 1970s, "indoor air quality" (IAQ) appeared in some Western countries IAQ)" statement. At that time, for the purpose of saving energy, the air tightness of buildings was greatly improved, which resulted in insufficient indoor ventilation rates, resulting in frequent indoor air pollution incidents. Some people experience symptoms such as headaches, dry coughs, dry and itchy skin, dizziness and nausea, difficulty concentrating, and sensitivity to odors. This condition, known as "sick building syndrome", occurs in many countries, including developed countries. There are painful lessons learned in this regard. The advent of the fresh air system has completely solved the ventilation and other problems of the house. Definition of fresh air system Fresh air system is a way to continuously discharge indoor dirty air in a timely manner 24 hours a day, 365 days a year, while introducing fresh outdoor air, effectively controlling the air volume, reducing energy loss, and improving indoor air quality. The fresh air system ensures that there is sufficient fresh air in the room and meets the following functions: 》》》It can remove a variety of indoor air pollution, bring you necessary and high-quality air, and avoid the noise trouble and frequent ventilation caused by opening windows. It eliminates the pain of cleaning indoors and the embarrassment of forgetting to close the windows when going out; 》》》It can guarantee to prolong the life of the building, especially to prevent the building from mold; 》》》Meet the requirements of building energy-saving regulations; 》》》It can ensure that it lasts for a long time, Continuous operation with high reliability, low energy consumption and low noise; 》》》Fresh air system is widely used in high-end residential areas, villas, hospitals, offices, hotels, KTV and other places. British CoAi Fresh Air System CoAi Fresh Air System is a residential ventilation method that continuously and can control the ventilation path. Through high-performance fans and air flow control systems, the replacement of fresh air is completely controlled. This technology has little impact on indoor temperature. At the same time, it also improves the comfort level of the human body indoors. It is an effective way to effectively solve the contradiction between energy saving and ventilation, and it is also a necessary condition for ecological residential standards. The working principle is: exhaust air is implemented in places with serious indoor pollution (kitchens, bathrooms, toilets, etc.). The indoor negative pressure formed by the exhaust air allows fresh outdoor air to continuously enter through the air inlets set on the window frame or inside the wall. Indoors, the paths and air volumes of exhaust and inlet air are allocated after strict calculations. In addition, the air inlet can perform basic filtering and noise reduction on the fresh air entering the room
