Factors affecting the life of air supply ceiling: multi-dimensional analysis
Factors affecting the life of air supply ceiling: multi-dimensional analysisThe life of the ceiling is not static but is affected by a variety of factors, just as the service life of a car will be affected by engine performance, driving road conditions, maintenance frequency, and other factors. Below, we deeply analyze the impact of these factors on the life of different grades of air supply ceilings from three key dimensions: filtration technology and materials, use environment and frequency, and maintenance measures.(1) Filtration technology and materials Different grades of air supply ceilings have significant differences in filtration technology and materials, and these differences, like different quality filters, directly determine the "purification strength" and service life of air supply ceilings. To achieve the highest degree of cleanliness, the ultra-efficient Particulate Air (HEPA) filter, made of a high-performance material such as glass fiber, is usually used to filter more than 99.99% of the time. It can intercept almost all pollutants such as dust, bacteria, and viruses in the air. However, this high-precision filtration also means that the filter needs to withstand greater pressure, as time goes by, pollutants gradually accumulate on the filter screen, resulting in increasing resistance of the filter, when the resistance reaches a certain degree, the performance of the filter will decline, or even fail, thus affecting the life of the entire supply ceiling. In general, under normal use, the high-efficiency filter of the 100-level supply air ceiling may need to be replaced every 6-12 months, and if the use environment is harsh, the replacement cycle may be shorter. Although the filter accuracy of the thousand-grade air supply ceiling is slightly lower than one hundred, it can also reach 99.9% or more, and its material may be a composite material of glass fiber and synthetic fiber, which ensures a certain filtering effect at the same time, relatively reduces the burden of the filter and has a relatively long service life. In the conventional use environment, the filter replacement cycle of the thousand-grade air supply ceiling is about 1-2 years. However, if there are more pollutants in the environment, or if the frequency of use is too high, the life of the filter will be shortened accordingly. The filter of 10,000 air supply ceilings usually uses ordinary synthetic fiber materials, and the filtration accuracy is relatively low, which is mainly used to filter larger particles of dust and odor. Due to its relatively low filtration requirements, the service life of the filter is relatively long, and the replacement cycle of the filter may be 2-3 years in the general use environment. However, if there is more dust in the environment, or if it is used continuously for a long time, the filter also needs to be replaced in advance. (2) Use environment and frequency The use of environment and frequency are like "invisible killers" that silently affect the life of the ventilated ceiling. The frequency of use and environmental conditions of operating rooms, ICU wards, and other places have a crucial role in the life of ventilated ceilings. In the operating room, frequent operation makes the supply ceiling need to run for a long time, which undoubtedly increases the wear and tear of the equipment. Every operation will produce a variety of pollutants, such as tissue debris generated during the operation, blood droplets, as well as bacteria and viruses carried by medical staff and patients. These pollutants will enter the filter and internal structure of the supply ceiling with the airflow, accelerating the aging and damage of the equipment. According to statistics, a busy third-grade hospital operating room may carry out dozens of operations every day, and the daily operation time of the air supply ceiling is as long as 10-12 hours or even longer, and the life of the air supply ceiling will be significantly shortened under this high-intensity frequency of use. In addition, the air quality in the use environment is also a key factor. If the air quality in the area where the operating room is located is poor, and the air contains a lot of dust, pollen, industrial pollutants, etc., then the filter of the air supply ceiling needs to withstand greater filtration pressure, and its life will be correspondingly reduced. In some heavy industry cities or areas with serious air pollution, the air supply ceiling filter of the hospital may need to be replaced more frequently to ensure its normal purification effect and service life. (3) Maintenance measures Maintenance is like the "life vitality agent" injected into the air supply ceiling, regular maintenance, cleaning, replacement parts, and other maintenance work, to extend the life of different grades of air supply ceiling plays a key role. Regular maintenance can find and solve the problems in the operation of the air supply ceiling in time to ensure that it is always in the best working condition. For example, regular cleaning of dust and pollutants on the filter surface can reduce the resistance of the filter, improve its filtration efficiency, and extend its service life. It is generally recommended to clean the filter every 1-2 months, using professional cleaning tools and methods to avoid damage to the filter. Timely replacement of aging or damaged parts is also an important part of maintenance. With the growth of use time, some parts of the air supply ceiling, such as fans, motors, seals, etc., will gradually wear or age, affecting the normal operation of the equipment. If problems with these parts are found, they should be replaced in time to ensure the performance and life of the air supply ceiling. For example, if the impeller of the fan is worn or deformed, it will lead to insufficient air volume or increased noise. At this time, the impeller needs to be replaced in time to ensure the normal operation of the fan. In addition, regular performance testing and debugging of the air supply ceiling is also essential. Through professional testing equipment, test the air volume, wind speed, cleanliness, and other parameters of the supply air ceiling to ensure that it meets the design requirements. If the parameters are abnormal, debug and maintain the device in time to ensure the normal running of the device. It is generally recommended to conduct a comprehensive performance test and debugging of the air supply ceiling every six months or a year. |
