PROBLEM TO BE SOLVED: To provide a heat exchange type ventilation device having high total enthalpy heat exchange efficiency and preventing the deterioration of performance caused by dew formation, in the heat exchange type ventilation device for domestic use and commercial use.SOLUTION: By using a material for a total enthalpy heat exchange element that is obtained by polymerizing at least one type of a low-molecular organic compound becoming a hydrophilic high-molecular compound by polymerization in a porous base material, a total enthalpy heat exchange element which has high latent heat exchange efficiency is hardly soluble in water and has high barrier performance is obtained. Thus, a heat exchange type ventilation device that has high total enthalpy heat exchange efficiency and prevents performance deterioration caused by dew formation can be obtained. |
