This paper deals with the analytical and experimental study on rotary total heat exchangers for winter time conditions. Rotary total heat exchangers can also operate in winter time under the same manner as summer time and save the energy of the heating and the humidification during ventilations. The experimental results for some winter time conditions show the increase of humidity efficiency and the decrease of temperature efficiency in the exhaust air side, differing from those numerical results. This tendency is investigated numerically under the consideration of the condensation of moist air. The results show to needs more considerations for the quantitative explanations.
