  By the way, in the air conditioning system as described above, when molecular pollutants are contained in the target air, the contaminants adhere to the coil fin portion, and the wetting performance is lowered. It was difficult to exhibit the AMC removal rate and the humidification efficiency. In addition, in the above example, nulls and algae are generated in the circulating water tank that stores and circulates the dripping water dropped on the cooling coil or the vaporizing humidifier that is a heat exchange coil, and the watering nozzle is clogged. There has been a problem that the wetting performance is further deteriorated due to the decrease in the amount of dripping water due to, and the pressure loss on the air side is also increased.
