We developed a new AMC (Airborne Molecular Contaminant) removal system of wetted-wall with the counterflow. The wetted-wall unit is composed of hydrophilic membrane matrix to which DI water is supplied. The DI water necessary for this system is small in amount (the water/gas ratio, Ls/G, is less than 0.01) . In the present work, we first conducted lab-scale experiment and then field experiments in order to evaluate the performance of the system. As a result, 1) the lab-scale experiment showed that the newly developed removal system has high removal efficiency, 2) the field experiment showed that the AMC removal system can maintain the high removal efficiency for one year, and AMC is removed mainly by trapping into the condensed water on cooling coil fins especially in summer, 3) even when the water/gas ratio is as small as Ls/G = 0.005, the wetted-wall with the counterflow system can maintain high removal efficiency.
