<p>PURPOSE:To reduce energy in the winter season by conducting ventilation having little heat loss, using living space as one of the paths of an air cycle while collecting solar heat by an external wall and a roof. CONSTITUTION:In winter, air taken in from a suction and exhaust port 11 is diffused into attic space 1 by a blower 13 through a heat exchanger 12, and moved into an underfloor space 3 through ventilation space 10. One part of air is shifted into wall collector space 6, heated by solar heat through an exter nal wall 5, and transferred into roof collector space 8. The air is heated by solar heat through a roof 7 in the space 8, moved into a heat collecting duct 16, dispersed into the underfloor space 3 through a pipe 22 and a dispersing duct 17 through a blower 18, mixed with air passing through the ventilation space 10, and introduced into living space 2 through an air inlet 14. Finally, the air is discharged from the suction and exhaust port 11 through the heat exchanger 12 and a pipe 20 through a ventilating fan 15. The blower 18 is stopped in summer. Accordingly, air in both collector space 6, 8 the role of heat-insulating layers.</p> |
