Personalized air conditioning displacement ventilation system

Abstract

A displacement ventilation system is located above a floor having an air plenum below the floor but above the concrete slab. A displacement ventilation workstation structure is located above the floor and thereby above the air plenum. An air fan is located below the floor and delivers air into flexible air ducts and from there into rigid upstanding air ducts. From there the conditioned air is delivered into rigid upstanding air ducts structure that is located under a workstation surface and has a front outlet that is controllable by a person sitting at the workstation. The upstanding duct has a lateral air opening or outlet which is opposite the direction of where air is delivered to the duct structure under the surface of the workstation. The outlet opening supplies the majority of conditioned air and is thereby delivered into the atmosphere of the work space at a very low velocity and at a point which is below the work surface of the workstation. This system does not create any uncomfortable air streams and air turbulences.

1 . A displacement air ventilation system in a workstation, said system is installed on a floor having an air plenum below said floor but above a concrete slab, a supply of air located in said plenum is moving air into a flexible air duct, said workstation is located above said floor and has an upstanding duct, receiving said conditioned air from said flexible duct, said workstation having a horizontal work surface, a duct located under said work surface and receiving said conditioned air from said upstanding duct, said duct having a frontal air outlet, said upstanding duct having an air opening in an outer panel of said upstanding duct, the majority of air in said upstanding duct is being supplied through said air outlet into the ambient atmosphere surrounding said workstation, said air outlet is located below said surface of said workstation surface.  
   
   
       2 . The displacement ventilation system of  claim 1 , wherein said workstation includes a back panel and a side panel.  
   
   
       3 . The displacement ventilation system of  claim 1 , wherein there are three air streams within said system, a first one emanating from said air fan located below said floor, a second one operating within said hollow wall and said duct under said workstation surface and a third one releasing a majority of the air through said opening in said outer panel.  
   
   
       4 . The displacement ventilation system of  claim 1 , wherein said system is a unitary duct assembly including said upstanding duct, said opening in said duct may be any size and location in an elevated position above said floor.  
   
   
       5 . The displacement ventilation system of  claim 1 , wherein said supply of air is moving air to one or more of said workstations.
