<p>PURPOSE:To significantly save the driving energy of cooler and heater by selecting a proper duct according to season to connect an indoor heat exchanger with the attic, under-floor, or rooftop space. CONSTITUTION:In summer, an indoor heat exchanger 1b dehumidifies the outside air sucked through a third duct 13 followed by temperature control, and then blows it to an attic space 3c through a second duct 12. The coldness of the air sucked from an underfloor space 3b through a fourth duct 14 is also recovered, and then discharged to the rooftop space through a first duct 11, a control box 16, and a fifth duct 15. In winter, on the other hand, the indoor heat exchanger 1b sucks the outside air heated by an air heat collector 2 through the first duct 11 followed by temperature control, and blows it to the underfloor space 3b through the fourth duct 14. The air in the attic space 3c is further sucked through the second duct 12 followed by temperature control, and then discharged to the outside through the third duct 13. Thus, solar heat can be effectively utilized to significantly reduce the load of cooler and heater.</p> |
