초록

Improvement of the enthalpy exchange element's energy efficiency is of current interest from anenergy-saving viewpoint. In this study, a LiCl-impregnated spacer was devised as a means to improve the performance of the enthalpy exchange element. Two samples were tested : one with and one without impregnated spacers of $338{\times}338{\times}380mm$ sizes with 2.0 mm channel spacing. The results showed that the temperature efficiencies of the two samples were approximately the same. The humidity efficiency, however, was strongly affected by the LiCl impregnation. The impregnated sample yielded a 9% higher humidity efficiency under cooling and the difference increased to 14% under aheating condition. It was anticipated that more moisture would beadsorbed on the LiCl-impregnated spacers, which was delivered to their roots and eventually to the air in neighboring channels. Separate moisture adsorption tests revealed that both the adsorption rate and the amount of the adsorbed moisture are higher for the LiCl-impregnated specimen.
