초록

Review the contents of Passive Ventilation Skin combined with BIPV suggested in this study is as follows. High-rise buildings are applied to the curtain wall facades to reduce the weight of the building. In this conditions, BIPV applied to the facades has the effect of increasing the added value, as well as economic efficiency. However, BIPV installed curtain wall's spandrels section generates the power generation efficiency decreases because of the difficult to exhaust to the rear. For this reasons, we propose Passive Ventilation Skin combined with BIPV that controls the exothermic of the PV module through a natural exhaust through this study. This member is composed of three layers-core for natural ventilation, exterior and interior materials based on the study of the 'Breathing Wall(BW)' developed in Japan and 'Passive Ventilation Skin(PVS)'. Natural ventilation takes place by the heat exchange in the multi-layer structure of the core material composed with the perforated aluminum sheets and air layers. And the electricity carried by the PV modules installed in the exterior material. The experiment of the member was conducted at outdoor conditions. Through the experiment, we measured the temperature of each part of the member and the power generation amount of the PV modules. Each items measured through the experiment are important indicator to exhibit the performance of the member in terms of controlling the exothermic of the PV modules. Result of the temperature measurement is as follows. Temperature of the PV module was not a large difference regardless of the period by the active exhaust of the member. And the air heated by the exothermic of the PV module caused a temperature rise in the indoor air in heating period. In terms of power generation of PV module, temperature of PV module of this member is being kept below 40 degrees. Normally PV module generates a reduction in power generation efficiency more than 40 degrees. Therefore power generation efficiency of this member is higher than the typical BIPV system enclosed structure.
