<p>PURPOSE:To provide a comfortable living space by arranging heat collection wall with air layer being enclosed between two plates by bringing a high temperature to the indoor in winter season and in turn a low temperature to the indoor in summer. CONSTITUTION:A heat collecting plate 1 consituted by such a material as having a high thermal conductivity, e.i. an iron plate, is cooled by radiational cooling during summer season lower than the surrounding air temperature. Due to this arrangement, the air in the air layer S1 enclosed in the outer wall chamber is cooled to form a descending air flow, and then flowed into the air layer S2 via lower air port 6. In turn, the upper portion of the air layer S1 becomes a negative pressure to suction the air in the air layer S2 from the air port 5. In this way, the air is circulated from the air layer S1, air port 6, air layer S2, air port 5 and the air layer S1. The air absorbs the indoor temperature via interior material 4, radiated outside via heat collecting plate 1, resulting in showing a low temperature. During this circulation, a temperature of the concrete wall 3 is gradually lowered and a cooled heat accumulation is performed.</p> |
