In the floor blowing out air conditioning system air conditioning manner, and the floor blowing out air conditioning system

摘要

PURPOSE: To suppress unevenness of diffused air flow rates to low without providing dampers at respective diffusers by lowering a height of an underfloor chamber in an air conditioning system in which an underfloor space is used as a conditioned air supply underfloor chamber and the air is supplied from the diffusers provided at a floor into a room. ;CONSTITUTION: Filters 41, 45 are respectively installed in diffusers 20 at an underfloor chamber. Conditioned air in the chamber is supplied into a room through the filters 41, 45. The filters used for all the diffusers have the same specifications, and static pressure performances of the filters 41, 45 are suitably selected. A passing resistance is increased by adding the filters, an outlet resistance coefficient is increased, and unevenness of diffused air flow rates is reduced.;COPYRIGHT: (C)1995,JPO
