Air Purification Devices Methods And Systems

Abstract

A device and method for air purification used in cooling, heating and air ventilation systems. The device has at least one UV light source positioned on an inside portion of a movable access panel so that it moves with the access panel from a first position where the UV source directs UV light towards the inside of the system to purify the air stream inside and to remove contaminants from the surfaces inside the system, to a second position where the UV source directs UV light towards the space surrounding the system so that it purifies the air in the room where the system is mounted.

1 . A chilled beam-type terminal unit, comprising:
 a housing with a heat exchanger configured for receiving chilled water;   a flow space with UV lamps, the housing having flow directing elements arranged to direct return and supply air through the heat exchanger and out of the housing while causing light from the UV lamps to shine on the air flowing therethrough;   the heat exchanger being arranged to serve as at least a portion of a light blocking mechanism and positioned between an inlet or an outlet of the housing.   
     
     
         2 . The unit of  claim 1 , wherein the heat exchanger is of a fin-tube type. 
     
     
         3 . The unit of  claim 1  wherein the UV clamps are positioned to illuminate the heat transfer surfaces of the heat exchanger. 
     
     
         4 . The unit of  claim 3 , further comprising a flow straighter that is positioned to block light emerging from either or both of the inlet and outlet of the housing. 
     
     
         5 . The unit of  claim 2 , further comprising a flow straighter that is positioned to block light emerging from either or both of the inlet and outlet of the housing. 
     
     
         6 . The unit of  claim 1 , further comprising a flow straighter that is positioned to block light emerging from either or both of the inlet and outlet of the housing. 
     
     
         7 . The unit of  claim 6 , further comprising a window, the window being positioned between an air flow path and the UV lamps. 
     
     
         8 . The unit of  claim 5 , further comprising a window, the window being positioned between an air flow path and the UV lamps. 
     
     
         9 . The unit of  claim 4 , further comprising a window, the window being positioned between an air flow path and the UV lamps. 
     
     
         10 . The unit of  claim 3 , further comprising a window, the window being positioned between an air flow path and the UV lamps. 
     
     
         11 . The unit of  claim 2 , further comprising a window, the window being positioned between an air flow path and the UV lamps. 
     
     
         12 . The unit of  claim 1 , further comprising a window, the window being positioned between an air flow path and the UV lamps. 
     
     
         13 . The unit of  claim 1 , further comprising a window that faces an exterior of the housing and having a frequency downconverting property to convert excess UV light from the lamps escaping therethrough into visible light. 
     
     
         14 . The unit of  claim 2  wherein the UV clamps are positioned to illuminate the heat transfer surfaces of the heat exchanger. 
     
     
         15 . The unit of  claim 3  wherein the UV clamps are positioned to illuminate the heat transfer surfaces of the heat exchanger. 
     
     
         16 . The unit of  claim 4  wherein the UV clamps are positioned to illuminate the heat transfer surfaces of the heat exchanger. 
     
     
         17 . The unit of  claim 5  wherein the UV clamps are positioned to illuminate the heat transfer surfaces of the heat exchanger.
