When using air conditioners, everyone will have this feeling: When the air conditioner is running for a long time, the indoor air will become turbid. In the "Life Tips" section broadcast by CCTV's 1 integrated channel, the indoor air problem of the air-conditioned room is tested. In the experiment, two laboratory workers in the small bedroom of 13 square meters, closed the door and window and opened the air conditioner for only one hour, the carbon dioxide concentration increased from 472ppm to 2088ppm, and it is still rising. In the program, CCTV "Life Tips" gives advice, Open the air conditioner for 1 hour to open the window and ventilate once, or buy a new fan. I found that CCTV News has reported this issue for 2 consecutive years.
At the beginning of August, the netizen @Peasfly also made an experimental test of closing the air conditioner in the window. The air conditioner was turned off at night to open the air conditioner. The indoor carbon dioxide concentration in the morning exceeded 3000ppm, which is equivalent to 8 times of the outdoor. This also confirmed that the air conditioning room air is not circulating. It can cause respiratory discomfort. In fact, the air conditioner should not open the window on the network, the attention has been very high, through Baidu search 'open air-conditioning window' entry, related information reached 4.77 million.
Then, what is the hazard of high indoor carbon dioxide concentration? According to researchers from the China Academy of Building Research, the national standard for indoor carbon dioxide concentration is generally below 1000ppm, when the human body feels fresh and comfortable; for densely populated places, such as shopping malls, schools, Generally, the concentration of carbon dioxide is below 1500ppm. When the indoor carbon dioxide concentration reaches 2000ppm, the human body will feel dizzy and uncomfortable.
Everyone knows that the usual window ventilation is a common method to solve indoor air ventilation and air circulation. However, in the air-conditioned room, ventilation of the window will inevitably sacrifice some of the cooling effect, and the indoor air will cause a burden on the air conditioner to cool down, not only will it Increasing the air conditioning power consumption will also affect the indoor air comfort. Moreover, once the outdoor smog, the air pollution is serious, the window ventilation may also increase indoor air pollution. Many netizens propose to buy new fans, but the purchase cost is higher. And the fresh air system can't be tempered, it needs to be used with air conditioner.
The window is not suitable for ventilation, and the cost of purchasing a new fan is high. Is there a solution with the best of both worlds? In response to this air problem, Haier proposes to combine the fresh air system with the air conditioner and carry the five-purification technology. Open the window to introduce the filtered fresh air, break the inherent concept of 'opening the window to breathe', and open a 'invisible window' for the family.
In addition, the author also learned the advantages of this product through a comparison video. In the same glass room, the ordinary air conditioner can not change the new air, the carbon dioxide concentration is always maintained at about 3000ppm. In Haier fresh air self-cleaning air-conditioned glass room, open After air conditioning, the indoor air in 15 minutes, the carbon dioxide concentration is reduced from 3000ppm to 595ppm, reaching the high quality air index.
At present, it has entered the autumn, but the hot weather is still there. When people stay in the air-conditioned room, they should always pay attention to the air quality. After all, staying in the dirty air for a long time will cause discomfort to the human body. It can be said that this Haier fresh air from the above The clean air conditioner solves the problem of elevated carbon dioxide concentration in the air-conditioned room. It can move fresh outdoor air into the room and keep the room constant.
