Abstract
Abstract A temperature control terminal unit includes a single-blade volume damper that is positionable by a motor driven operator in accordance with the temperature setting on a thermostat. The volume damper reduces the volume of air delivered to the area being conditioned as the temperature within same approaches a desired value. The unit is further characterized by its ability to utilize the proper volumetric proportions of air for either heating or cooling without upsetting the balance of air in the system and may include a remote supplementary heating source energizable in accordance with the damper position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
A temperature control terminal unit, said unit operable to be utilized with an air conditioning system having a primary air source and at least one duct associated therewith, said unit comprising an inlet opening, said opening operable to be interconnected to said air duct from the primary air source, at least two outlet openings located in said unit downstream from said inlet opening, one of said outlet openings in communicating relationship with an area being temperature conditioned by said unit, the other of said outlet openings in communicating relationship with a return air means, means for dividing the flow of air from said primary air source between said outlet openings in accordance with only the temperature of the area being conditioned, said dividing means having a plurality of positions, and means located on said dividing means for providing a substantially consistent pressure drop within said unit regardless of the position of said dividing means.
Claim 2
Dependent Claim
154 words
A temperature control terminal unit, said unit operable to be utilized with an air conditioning system having a primary air source and at least one duct associated therewith, said unit comprising an inlet opening, said opening operable to be interconnected to said air duct from the primary air source, at least two outlet openings located in said unit downstream from said inlet opening, one of said outlet openings in communicating relationship with an area being temperature conditioned by said unit, the other of said outlet openings in communicating relationship with a return air means, means for dividing the flow of air from said primary air source between said outlet openings in accordance with only the temperature of the area being conditioned, said dividing means having a plurality of positions, and means located on said dividing means for providing a substantially consistent pressure drop within said unit regardless of the position of said dividing means.
Claim 3
Dependent Claim
102 words
The invention as in claim 1 wherein said dividing means includes a damper, said damper being swingably mounted within said unit and operable to divert complementary portions of said air flow entering said unit from said inlet through said outlet openings, the volumetric size of said complementary portions of said air flow being dependent on the position of said damper, and means foR moving said damper in accordance with the temperature of said area being conditioned, said moving means being operable to reduce the volume of said air flow into said area as the temperature of said area approaches a desired value.
Claim 4
Dependent Claim
207 words
A temperature control terminal unit, said unit operable to be utilized with an air conditioning system having a primary air source and at least one duct associated therewith, said unit comprising an inlet opening, said opening operable to be interconnected to said air duct from the primary air source, at least two outlet openings located in said unit downstream from sad inlet opening, one of said outlet openings in communicating relationship with an area being temperature conditioned by said unit, the other of said outlet openings in communicating relationship with a return air means, a damper, said damper being located within said unit downstream from said inlet opening and operable to divert complementary portions of said air flow through and out of said outlet openings, a pivot rod, said damper being fixedly attached at one end thereof to said pivot rod, means for moving said pivot rod and said damper in accordance with the temperature in said area being temperature conditioned, and diffusing vanes located between said damper and one of said outlet openings, said vanes operable to direct the air flow through said one of said openings, and means for providing a substantially consistent pressure drop within said unit regardless of the position of said damper.
Claim 5
Dependent Claim
207 words
A temperature control terminal unit, said unit operable to be utilized with an air conditioning system having a primary air source and at least one duct associated therewith, said unit comprising an inlet opening, said opening operable to be interconnected to said air duct from the primary air source, at least two outlet openings located in said unit downstream from sad inlet opening, one of said outlet openings in communicating relationship with an area being temperature conditioned by said unit, the other of said outlet openings in communicating relationship with a return air means, a damper, said damper being located within said unit downstream from said inlet opening and operable to divert complementary portions of said air flow through and out of said outlet openings, a pivot rod, said damper being fixedly attached at one end thereof to said pivot rod, means for moving said pivot rod and said damper in accordance with the temperature in said area being temperature conditioned, and diffusing vanes located between said damper and one of said outlet openings, said vanes operable to direct the air flow through said one of said openings, and means for providing a substantially consistent pressure drop within said unit regardless of the position of said damper.
Claim 6
Dependent Claim
175 words
A temperature control terminal unit, said terminal unit operable to be utilized with an air conditioning system having a primary air source and at least one duct associated therewith, said unit comprising an inlet opening, said opening operable to be interconnected to said air duct from a primary air source, at least two outlet openings located in said unit downstream from said inlet opening, one of said outlet openings in communicating relationship with an area being temperature conditioned by said unit, the other of said outlet openings in communicating relationship with a return air means, a swingable damper located within said unit downstream from said inlet opening, means for positioning said damper in accordance with the temperature in said area being conditioned, means for providing a substantially consistent pressure drop within said unit regardless of the position of said damper, and wherein said providing means includes a means located on said damper for assuring a resistance to air flow from said inlet opening and out said outlet openings regardless of the position of said damper.
Claim 7
Dependent Claim
175 words
A temperature control terminal unit, said terminal unit operable to be utilized with an air conditioning system having a primary air source and at least one duct associated therewith, said unit comprising an inlet opening, said opening operable to be interconnected to said air duct from a primary air source, at least two outlet openings located in said unit downstream from said inlet opening, one of said outlet openings in communicating relationship with an area being temperature conditioned by said unit, the other of said outlet openings in communicating relationship with a return air means, a swingable damper located within said unit downstream from said inlet opening, means for positioning said damper in accordance with the temperature in said area being conditioned, means for providing a substantially consistent pressure drop within said unit regardless of the position of said damper, and wherein said providing means includes a means located on said damper for assuring a resistance to air flow from said inlet opening and out said outlet openings regardless of the position of said damper.
Claim 8
Dependent Claim
70 words
The invention as in claim 4 wherein said resistance assuring means includes an air stabilizer fixedly attached to said damper, said stabilizer having at least a portion thereof extending angularly from a surface of said damper so that said stabilizer offers more resistance to said air flow from said inlet opening than does said damper when said damper is in a preselected angular position with respect to said inlet opening.
