Cinema fresh air system, cinema fresh air dehumidification integrated machine technology trends: as we all know, this year's Spring Festival films are particularly popular, with seven films including Hello, Li Huanying, Chinatown Investigation 3, Assassination of Novelists, Bears Appear in the Wild Land, New God List: Nezha Reborn, Order to Serve God, and Crowd of People successively landing on the national screens; As the epidemic situation in China has been basically under control, people have come to the cinema to watch movies during the Spring Festival, making the box office of this year's Spring Festival films continue to create new records
According to statistics, as of 0:00 on February 18, the total real-time box office of Spring Festival films had exceeded 8 billion yuan, far exceeding the box office of the same period in previous years. At the same time, a number of world records such as the single day box office in the global single market and weekend box office in the global single market have been refreshed. The major cinemas across the country are overcrowded, and even some remote cinemas with poor hardware facilities can be fully occupied. However, it is this behavior of watching movies in groups that has led to a similar incident of collective carbon monoxide poisoning in Zhejiang Dongyang Cinema
Dozens or even hundreds of people crowded in a narrow space for a long time, with poor air flow and insufficient ventilation equipment, resulting in the reduction of oxygen content in the theater, the increase of carbon monoxide content, and the human body subsequently suffered from anoxic reaction. If the concentration of carbon monoxide inhaled by the human body is too high, it will cause hypoxia in various organs of the human body, and people are prone to dizziness, nausea and other symptoms, even endangering life. At about 18:00 on February 17, in a movie theater in Dongyang, Zhejiang Province, many audiences who were watching the film had suffered from dizziness, nausea, vomiting and other adverse symptoms. Later, the local health department sent all 63 spectators present to the hospital for physical examination
According to the preliminary judgment, the excessive concentration of carbon monoxide in the cinema is the main reason for the discomfort of these audiences. There are many factors that cause carbon monoxide exceeding the standard. The concentration of people is too dense, the air is not circulating, the airtight ventilation of the space is not good, and the coal and wood are not fully burned, which are likely to cause the carbon monoxide content in the air to exceed the standard. In the past, many families used to burn coal and charcoal for heating. When the fire was not completely extinguished, the carbon monoxide content in the air would be too high. After people breathe, they would have the symptom of "gas poisoning", that is, carbon monoxide poisoning
In modern society, it is a pursuit of high-quality life. The PD668XF lifting fresh air dehumidifier and the Parkoo series central fresh air dehumidifier are the most effective solutions to the problems of indoor air pollution and humidity.

Core Tip. For example, in most cinemas, except for the Spring Festival, the attendance rate is not high most of the time, and only a small amount of ventilation facilities are installed symbolically; They also rarely considered the possibility of poor air circulation, which led to the occurrence of carbon monoxide poisoning in the audience
The epidemic has not completely disappeared, so it must be well protected in closed public places such as cinemas, gyms, KTVs, Internet cafes, etc. So, how should such a closed space be ventilated? It is necessary to install fresh air dehumidification system in most public places such as cinemas, gyms, KTV, Internet cafes, etc!
