Abstract: A rotary heat exchanger includes: a tubular-shaped heat transfer tubular body (3) which is rotatable with a central axis (C) as a rotation center, which allows a first medium (11) to flow therein, and outside of which a second medium (12) having a temperature different from a temperature of the first medium (11) flows; a central member (2) which is provided on an inner side of the heat transfer tubular body (3) in a radial direction and which is fixed coaxially with the heat transfer tubular body (3); and an outer sliding contact member (6) which is in sliding contact with an outer circumferential surface of the heat transfer tubular body (3), and the heat transfer tubular body (3) is rotatably supported with respect to the central member (2) via bearings (17, 18) disposed at two end portions of the central member (2) in an axial direction.

Abstract: A latent heat storage device includes: a heat transfer cylindrical body allowing a flow of a heat medium inside thereof and being rotatable about a longitudinal axis as a center of rotation; a fixed blade being adjacent to or in a slidable contact with an outer peripheral surface of the heat transfer cylindrical body; and a latent heat storage material disposed around the heat transfer cylindrical body, wherein by rotation of the heat transfer cylindrical body, the fixed blade scrapes a solidified body of the latent heat storage material adhering to the outer peripheral surface of the heat transfer cylindrical body off the outer peripheral surface of the heat transfer cylindrical body, and creates circulation of the latent heat storage material.
