A total heat exchanger in accordance with a preferred embodiment includes air-guiding means (21), a heat-pipe heat exchanger (31) and a total heat exchange member (41). The air-guiding means is for providing a first airflow from outdoors and a second airflow from indoors. The heat-pipe heat exchanger includes at least one heat pipe (32) spanning across said first and second airflows simultaneously for conducting a sensible heat exchange between the airflows. The total heat exchange member is capable of exchanging sensible heat and latent heat between said first and second airflows, and defines therein a first air passage and a second air passage intersecting with and isolated from each other. A total heat exchange of sensible heat and latent heat between the first and second airflows is carried out in the total heat exchange member when the airflows flow through the first and second air passages respectively.
