PROBLEM TO BE SOLVED: To simply estimate a heat-transfer coefficient that is one of indicators of heat insulation properties.SOLUTION: A heat-transfer coefficient test device includes a plate-like member (21), a heating member (22), and first and second temperature sensors (25,24). The plate-like member (21) has a front surface (21a) that abuts an interior side surface of a surface member, and a rear surface (21b) opposite thereto, and has a known heat-transfer coefficient. The heating member (22) is provided on the rear surface side of the plate-like member, and transmits heat to the surface member via the plate-like member. The first and second temperature sensors (25,24) are provided on the front and rear surfaces of the plate-like member, respectively. The test device can be used to estimate a heat-transfer coefficient of the surface member, based on a front surface temperature and a rear surface temperature of the plate-like member, an outdoor side surface temperature of the surface member, and the heat-transfer coefficient of the plate-like member.SELECTED DRAWING: Figure 2 |
