PENTHOUSE COOLING/RETURN AIR DISTRIBUTION ASSEMBLY
First Claim
1. An air distribution assembly for use with a server room cooling system, comprising:
- an adjustable return air duct assembly configured to receive heated return air wherein the return air duct assembly has a tubular housing with a leading edge portion connected to sidewalls with trailing edge portions spaced apart from each other and defining a return air opening in communication with an interior area configured to carry the heated return air, and an airflow damper being positioned within the housing and moveable relative to the return air opening to block at least a portion of the return air opening and control a flow of the heated return air from the interior area through the return air opening; and
a pair of spaced apart, arcuate cooling air deflectors positioned on opposing sides of the housing and defining a mixing area between the deflectors and adjacent to the return air opening, the deflectors having leading end portions spaced apart from the sidewalls of the housing to define cooling air inlets configured to receive cooled air from the server room cooling system that flows around the leading edge portion of the housing and to direct the cooled air into the mixing area, the cooling air deflectors having trailing end portions spaced apart from each other and defining a mixed air outlet in communication with the mixing area and configured to direct a mixture of the cooled air and the heated return air into a server room;
Wherein the airflow damper is adjustable relative to the housing to control a temperature of the mixture of the cooled air and the heated return air directed into the server room.

Abstract
A cooling air distribution assembly with a housing having an interior area, and spaced-apart trailing edge portions defining an airflow opening in communication with an interior area. An airflow damper positioned within the housing is moveable relative to the airflow opening to control heated airflow from the interior area. Deflectors on opposing sides of the housing define a mixing area adjacent to the airflow opening. The deflectors have leading ends spaced apart from the housing to define air inlets that receive a cooling airflow into the mixing area. Trailing end portions of the deflectors define a mixed air outlet adjacent to the mixing area. The airflow damper is adjustable relative to the housing to control a temperature of the mixture of the cooling airflow and a portion of the flow of heated air passing through the mixed air outlet.

10. An air distribution assembly, comprising:
-
an interior air duct assembly having a housing with an interior area and having a leading edge portion and spaced apart trailing edge portions defining an airflow opening in communication with the interior area, the interior air duct assembly having an airflow damper positioned within the housing and moveable relative to the airflow opening to control a flow of the heated air out of the interior area through the airflow opening; and deflectors positioned on opposing sides of the housing and defining a mixing area between the deflectors and adjacent to the airflow opening, the deflectors having leading end portions spaced apart from the housing to define air inlets configured to receive an airflow around a portion of the housing and into the mixing area, the deflectors having trailing end portions spaced apart from each other and defining a mixed air outlet in communication with the mixing area and configured to direct a mixture of the airflow and a portion of the flow of heated air away from the mixed air outlet; wherein the airflow damper is adjustable relative to the housing to control a temperature of the mixture of the airflow and a portion of the flow of heated air passing through the mixed air outlet. - View Dependent Claims (11, 12, 13, 14, 15, 16, 19, 20)

17. An air distribution assembly for use with a server room cooling system, comprising:
-
an adjustable return air duct assembly configured to receive heated return air from a server room, wherein the return air duct assembly has an elongated housing with a closed leading edge portion, arcuate sidewalls with spaced apart trailing edge portions defining a return air opening opposite the closed leading edge portion and in communication with an interior area through which the heated return air from the server room can flow, the return air duct assembly having an airflow damper concentrically positioned within the housing and moveable relative to the return air opening to partially or fully block the return air opening and control a heated return airflow out of the housing through the return air opening; and A pair of spaced apart, arcuate cooling air deflectors positioned on opposing sides of the housing and defining a mixing area between the deflectors and adjacent to the return air opening, the cooling air deflectors having leading end portions spaced apart from the sidewalls of the housing to define cool air inlets configured to receive cooled air flowing around the leading edge portion of the housing and to direct the cooled air into the mixing area to mix with the heated return airflow exiting the housing through the return air opening, the cooling air deflectors having a pair of spaced apart trailing end portions defining a mixed air outlet in communication with the mixing area and configured to direct a mixture of the cooled air and the heated return air into the server room; Wherein the airflow damper is adjustable relative to the housing to control the amount of heated return air entering the mixing area to mix with the cooled air to control a temperature of the mixture of the cooled air and the heated return air directed into the server room. - View Dependent Claims (18)
