Fan Linkage Series

In recent years, with the vigorous development of real estate in our country, the number of new buildings has increased sharply, the dust in the supporting elevator car is large, and the smell of decoration materials is strong, which has become a fairly common problem. In the use of elevators, because the elevator car is relatively closed and crowded, how to efficiently and safely kill airborne pathogens such as influenza virus, SARS, tuberculosis, etc. has become an urgent problem for elevator passengers and elevator companies to solve.

Ultraviolet light can kill almost all viruses and bacteria known now, but it has different killing times for different bacteria. According to a study by Dong Xiaoping, an expert from the Institute of Viral Disease Control and Prevention of the Chinese Center for Disease Control and Prevention in 2003, the survivability of the Severe Acute Respiratory Syndrome (SARS) coronavirus was stronger than originally estimated, but methods such as high-temperature disinfection and ultraviolet irradiation can effectively kill SARS. . The researchers also simulated sunlight under natural conditions and tested the ability of ultraviolet rays in sunlight to kill coronaviruses. The results found that in the sunny weather at 10 am in May in Beijing, ultraviolet irradiation for three hours can kill the SARS virus, and on a cloudy day. The killing ability of medium ultraviolet rays is relatively reduced.

In the current domestic elevator car air management, there are very few elevators installed with ultraviolet sterilization devices. This does not mean that our elevators do not need to be installed, but the awareness and actions of our elevator passengers and elevator companies have not yet reached such a level of attention. At present, in China, it is mandatory for medical elevators to install ultraviolet sterilization devices. However, due to their limited working hours, the sterilization is generally 30 to 60 minutes after the elevator is out of service, which has no sterilization effect on the air of the car in use. This is a Major flaw! But it is also a major advantage of Heshan elevator car air purifiers. Heshan purifiers can continuously sterilize when people are riding in the car, and can avoid the harm caused by ultraviolet rays to the human body.

Heshan has been committed to the research of elevator car air temperature regulation, air purification and other fields.On the basis of the first-generation TYUV series elevator car ultraviolet sterilization system, it has carried out long-term in-depth cooperation with domestic universities and scientific research institutions, and developed a highly intelligent second-generation TJHQ series elevator car air purifier.And commissioned the Shanghai Center for Disease Control and Prevention to test its sterilization efficiency.The results show that after 60 minutes of action, it can kill Staphylococcus albus in a 20m³ laboratory. The rate is 99.86%--99.90%, which is very efficient.

To solve the odor of decoration materials, we use anatase TiO2 nanomaterials to make photocatalyst coatings. Under the action of ultraviolet light, electrons (eˉ) in the valence band transition to the conduction band, producing corresponding electrons in the valence band. Holes (h+), generate superoxide ion radicals, hydroxyl radicals, and superoxide hydroxyl radicals with extremely strong oxidizing effects, which can not only remove formaldehyde, benzene, toluene, xylene, TVOC and other toxic and harmful gases, pollutants, Odor and other oxidative decomposition into harmless CO2 and H2O, and has high-efficiency and broad-spectrum disinfection performance, and has a good inhibitory and killing effect on various common pathogenic bacteria.Generally, antibacterial agents only have bactericidal effect, but cannot decompose toxins. Photocatalysts can completely decompose bacterial remains and residual toxins in the body to achieve the purpose of thorough disinfection and sterilization. The photocatalyst itself does not change or lose in the process of action, but only provides a reaction place. It has the advantages of continuous action, stable properties, safety and non-toxicity, and does not produce secondary pollution. It is a green and pollution-free product.

TJHQ series air purifiers have absorbed years of market experience and technological innovation achievements, and adopted a number of advanced technologies such as nano-photocatalyst technology, high-quality imported ultraviolet lamps, and high-efficiency filtration systems. and other five excellent performance.It can be installed in conjunction with elevator air conditioners or elevator fans, suitable for hospitals, shopping malls, office buildings, hotels and other places.It has been successfully used in Beijing Daxing New Airport, Tianjin Municipal People's Congress, Shanghai International Finance Center, Guangdong Provincial Party Committee, Shenzhen Pingshan Maternal and Child Health Hospital, Chongqing Jiangbei Airport, Chengdu Oriental Plaza, Xi'an Laian Center, Xinjiang Karamay Airport, Yinchuan Vanke City Lights, Shenyang Plaza 66, Shanxi Construction Bank, Qingdao Haier Board of Directors Building, Hubei Rural Credit Cooperative Association, Nantong Municipal Government, The First Affiliated Hospital of Nanchang University, Hangzhou Civic Center, Wenzhou State Grid, Changsha Kailin International Building, Fuzhou Rongqiao Center, Yunnan First People's Hospital, Kunming Hang Lung Plaza and other projects.
