84 disinfection filter ultraviolet sterilizes the air
subway air conditioning safety passengers can rest assured
Yangtze River Daily News (Reporter Guo Jia Correspondent Zeng Siqidou) The weather is getting hotter and the subway air conditioner is on. "The air conditioners in my house are cleaned and disinfected every year. Is the subway air conditioner also very clean?" Many citizens are curious about the sanitary condition of the subway air conditioner. A reporter from the Yangtze River Daily found on the 18th that the subway air conditioner was not only cleaned and disinfected, but cold air was blown into the cabin, and ultraviolet lamps were also used to eliminate the air to ensure clean air in the cabin.
On the morning of the 18th, eight maintenance workers were busy in the train inspection warehouse on Line 7 of the Yezhihu Depot of the Wuhan Metro. Their job on that day was to clean and eliminate the subway air-conditioning filters and equipment.
Because the subway air conditioner is located on the top of the subway train, the entire operation work is completed at a high place, and the staff performs the relevant protection to perform the division of labor, some disassemble the air conditioner filter, some clean the equipment, and some install the clean filter Into the device. In order to improve work efficiency, the first part of the subway vehicle has also independently developed portable filter cleaning equipment, which can be taken directly to the cleaning site. The reporter saw that the removed filter was placed on the operating platform, and two staff members cooperated with the machine to complete the washing work, and then handed it to the machine to air dry. The cleaned filter net is then disinfected with 84 disinfection water.
Chen Tao, leader of the air-conditioning team in the maintenance workshop, said that the sanitation of subway air-conditioning is directly related to the health of every passenger. As the staff behind the maintenance of subway equipment, they strictly implement relevant prevention and control requirements in their work and eliminate air-conditioning filters. After the portable filter cleaning equipment completes a day's work, they will also carefully clean and disinfect it to avoid cross-infection of bacteria.
At the air conditioning equipment port, maintenance worker Fang Wanning was wiping the machine. He pointed to the open air-conditioning hybrid wind cabin and told reporters that after the outdoor fresh air enters the hybrid wind cabin, a set of ultraviolet disinfection devices here will sterilize them. In other words, the cold air that finally enters the subway car is "tested" by layers, and passengers can rest assured.
According to reports, these maintenance personnel can complete the in-depth cleaning of 144 air-conditioning filters in a day, and the entire Wuhan Metro network can clean more than 1,000 air-conditioning filters every day.
