Title:
METHOD AND APPARATUS FOR VENTILATING
Document Type and Number:
Japanese Patent JP3171710
Kind Code:
B2
Abstract:
PURPOSE: To perform an efficient substitution ventilation and to eliminate a discharge duct by blowing conditioned air from a lower part of a room into the room at a low speed, generating a high speed air jet flow in the vicinity of a ceiling in a horizontal direction, and discharging the air in the room by the generated air flow from a discharge port near the ceiling.
CONSTITUTION: When the air near the ceiling in a room 1 is sucked and discharged by a blower 7, a high speed air jet flow is blown from nozzles 9-17 via a small-diameter duct 8 in a horizontal direction. The air guided and conveyed by the jet flows flown from the nozzles 14, 17 is conveyed to an area to be guided and conveyed by the jet flow to be flown from the nozzle 11, the air in the room near the ceiling is similarly fed to a discharge port 18, and forcedly discharged by a ventilation fan 19. On the other hand, since conditioned air is supplied from a substitution ventilation diffuser 4 to the vicinity of a lower floor 2 in the room 1 at a low speed, substitution ventilation in the room 1 can be efficiently conducted. Accordingly, it is not necessary to provide a discharge port and a discharge duct in a space under a roof.
