Measurements and analysis of paper-based evaporative cooling pad impact on filtering performance to solid particles

According to the measurement method recommended by national standard of GB/T 18801-2015 Air Cleaner, tests and analyses the filtering performances of paper-based evaporative cooling pad to different size inhalable solid particles under the conditions of different particle concentrations, water distribution densities and air face velocities with Arizona test dust particles. The result shows that the filtering efficiency is very high, irrelative to particle concentration and pad condition, but highly correlative to water distribution density and air face velocity.
