空气过滤器寿命实验研究及经济性分析*
Experimental study and economic analysis of air filter service life
摘要：
对过滤器试样的阻力与计重效率进行了实验测试，探究了过滤器容尘-阻力、容尘-效率的变化规律，并依据Eurovent 4/11提出的能效计算方法对过滤器的能耗进行了计算。研究发现，过滤器产生的电费随使用时长的增加及阻力的增大而增大。基于过滤器更换费用、运行电费和综合费用的分析，提出了确定过滤器更换时间的方法，计算结果表明，过滤器的实际使用寿命高于GB/T 14295—2008中规定的使用寿命。对于一般民用建筑的空气过滤器，应当综合考虑单位风量的更换成本和运行电耗成本来确定过滤器的更换时间。
Abstract：
Measures the resistance and weight efficiency of the air filter samples on an experimental platform. Investigates the variation of the resistance and efficiency of the samples with the dust accumulation. Calculates the energy consumption of the filters using the energy efficiency calculation method in Eurovent 4/11. Finds that the power consumption cost of the filter increases with the increase of service time and filter resistance. Determines the replacement time of the air filter by analysing the replacement cost, operation power cost and comprehensive cost. The calculation results show that the actual service life of the filter is longer than that specified in the GB/T 14295-2008 standard. For the air filters in general civil buildings, the replacement cost of unit air rate and the operation power consumption cost should be comprehensively considered to determine the replacement time of filters.
