The National Hygiene Regulations for Central Air-conditioning and Ventilation Systems require that central air-conditioning in public places must be cleaned and disinfected before use; if the central air-conditioning and ventilation system does not meet the sanitary requirements, the sanitary facilities in public places shall be deemed to be inconsistent with sanitary standards and requirements, and no new Issue and renew the sanitation license for public places. Because the cleaning cost of central air conditioners is relatively high, a full cleaning of a larger area is at least tens of thousands or even hundreds of thousands of yuan at a time, so many units have not cleaned central air conditioners for many years. Experts said that to eliminate Legionella, the cooling water, ventilation pipes, and air outlets of the central air conditioner should be cleaned and disinfected regularly, and it is best to clean them once a year. According to disease control experts, cooling water, which is essential for air conditioning and refrigeration, is a breeding ground for Legionella bacteria. This is due to the accumulation of some nutrients in the cooling water in the process of continuous circulation and filtration. Coupled with suitable temperature conditions, bacteria can easily multiply in it. If the cooling water is contaminated, Legionella is most likely to be transported to various places in the room along the air-conditioning pipes. Some large public places such as office buildings and hotels have become blind spots for supervision. According to the health inspection of central air conditioners in public places by the disease control department, Legionella bacteria are detected in the cooling water of central air conditioners almost every year. Legionella pneumophila, also known as Legionella pneumophila, is a pathogen that easily causes diseases of the respiratory system, especially the lungs. After infection, it often causes symptoms such as cough and fever, leading to pneumonia; severe cases can cause respiratory failure, kidney failure, and even death. The air distribution system has a history of more than 30 years. The quality has been recognized by customers in all walks of life. In China, the air distribution system is still in its infancy, while other countries have been using it for many years in order to achieve energy conservation and environmental protection. In the next development, we hope that China itself can gradually use the air distribution duct system in this respect, and raise the air-conditioning pollution, ventilation and energy saving, emission reduction and environmental protection to a new level. The air distribution duct produced by Shanghai Environmental Technology Co., Ltd. will allow you to achieve the best results in terms of air conditioning, ventilation, pollution, energy conservation and environmental protection. Due to the easy cleaning and maintenance of the Jiutian brand air duct system and low cost, more and more public places tend to use the Jiutian brand air duct system as the end air supply system.
