<p>PURPOSE:To conserve energy by forming a sunlight outer wall into a double outer shell structure in which the sunlight outer wall is sloped and formed by a sunlight permeating material, and using double wall spaces as hot air chambers with switches to communicate with the air conditioner. CONSTITUTION:In the sunshine duration in winter season, air introduced through an outer air duct 5 and a suction port 11 passes through a ventilation duct 4 with a switching device D2 opened and enters into a hot air chamber 1. The air thus introduced is heated by sunlight permeating through an outer wall 9, passing through the switching device D2, air conditioner 2, air supply duct 3, and blow off outlet 10, and heats the chamber as indicated by dotted line arrows. In the non-sunshine duration, only a switch device D1 is closed to circulate air within the chamber. In summer and intermediate seasons, switches D1, D4 and D5 are opened, and switches D2 and D3 are closed, to divide air into the circulation system and the natural ventilation system of the air conditioner 2. By this construction, the solar energy absorption efficiency can be improved and the energy conservation can be realized.</p> |
