<p>PURPOSE:To eliminate the problem in aeration, dehumidifying, cooling, heating, snow melting and the damped condition in rainy season by a method wherein an under-floor space and a roof truss space of a building of which outer walls and roof are thermally insulated and under-floor part is wet-proofed are connected with wall clearances and partition clearances, upper aeration ports and lower aeration ports are arranged in an interior parts, and they are controlled by a controller. CONSTITUTION:In summer season, air is blown from a slit pipe 13 toward a ground under a floor by a ventilation fan 26 placed in an under-floor space 17, mixed with cold air in under-floor part, rises up through wall clearances 18 and partition clearances 19 and then discharges hot air in a roof truss space 16 to the outer air. An interior part 24 receives cold air through inner walls to release heat into the wall clearances 18 and the partition clearances 19. In the interior part 24, air at the under-floor part flows from lower aeration ports 30 and pushes out hot air from upper aeration ports 29. At night, a wall temperature switch and a roof temperature switch each shows a value less than 25 deg.C, air is forcedly fed from ducts 58-60 to each air layer under operation of ventilation fans 61-63, dumps heat from the roof and wall surfaces and then recovers cold air into a building.</p> |
