Hotel fresh air ventilator

Hotel fresh air ventilatorHow to maintain it mainly includes the following points:

1. Monitoring and maintenance of departments and medical staff;

2. Monitor the disinfection time, service life, and maintenance of ultraviolet lamps and machines: methods include registering the start and end time of disinfection, cumulative lamp time, machine operation, maintenance time and methods, etc. Some experts will check the disinfection records during the inspection. With the maturity of this technology, many machines now come with recording functions that hospitals can also purchase.

3. Monitoring the effectiveness of air disinfection: Regular (usually quarterly) microbiological monitoring is conducted after sampling the air and object surfaces. If infection occurs, relevant investigations are conducted at any time to indirectly evaluate the disinfection effect of the circulating air ultraviolet disinfection machine.

4. Clean the surface of the disinfection machine 1-2 times a week. Attention: Turn off the power before cleaning the machine.

5. Maintenance and upkeep by manufacturers or professionals

6. Monitoring of UV irradiation intensity: The UV lamp in the circulating air UV disinfection machine is a high-intensity lamp tube. In this case, the UV irradiation intensity inside the machine is ≥ 1800 μ W/cm? The ultraviolet radiation meter or indicator card installed in the hospital cannot detect it and requires specialized equipment. Only the manufacturer can be requested for monitoring. Moreover, the technical parameters of qualified disinfectors specify the lifespan of ultraviolet lamps. For hospitals, there is no need to measure the intensity of ultraviolet lamps, they only need to replace them according to the accumulated usage time, or refer to the product manual for maintenance and upkeep.

7. Filter cleaning: The frequency and method of cleaning should be determined according to the user manual, in addition to considering environmental cleanliness, usage time, and range. When the pollution in the place of use is severe, there is a lot of dust found (such as during infrastructure construction), or when the use time is long and the scope is wide, it is advisable to increase the cleaning frequency and record it in detail. Each hospital should comprehensively consider the above factors based on the instructions and actual situation, and negotiate and establish more scientific regulations with the equipment department and manufacturers.

8. The internal cleaning of the machine and the cleaning of the ultraviolet lamp tube should also be carried out regularly and recorded.
