Research Abstract |
The air cleaning effect with humidity swing method was studied. In the method, the suspended particulate matters (SPM) of nano- to micrometer size and the gaseous chemical substances are removed from the air through a thermal humidification and dehumidification process of the air. The air cleaning effect and required electric energy were experimentally studied. The SPM removal effect of about 80 % was shown in the experiment under low air flow rate of 3 L/min with plate fin type heat exchangers at absolute humidity swing of 0.2 kg/kg. For the chemical substances removal effect, it was shown that about55 % of ammonia can be removed under inlet condition of 670 ppm. It was also demonstratedthat the electric power can be reduced to 1/8 with introducing a heat pump system.
