PURPOSE:To improve the heat exchanging efficiency of a total heat exchanger, and increase the migration proofness of an air flow by a method wherein two kinds of air flows are partitioned by using an improved quality base material which is made by coating or impregnating of a capillary tube active substance on a fine porous base material. CONSTITUTION:A total heat exchanger is composed of partitioned two kinds of air flows for performing the total heat exchanging by utilizing an improved quality base material which is coated or impregnated a capillary tube active substance on a fine porous base material. For the capillary tube active substance, an interfacial activator having two kinds of nature, that is, a hydrophobic nature or a lipophilic nature, and a hydrophilic nature is utilized. An organic acid derivative is alos effective. For the purpose of improving the denseness due to the embedding of small holes in the base material, the capillary tube active substance is adhered on the fine porous base material at the rate of 5- 50wt%. For the improved quality base material which is obtained by coating or impregnating of the capillary tube active substance on the fine porous base material, the permeability to air is desirable more than 50/sec in Gurley's permeability to air. |
