  • Element for user in a heating and air conditioning ductwork system
    Patent number: 5197920
    Abstract: An element for use in ductwork of a heating and air conditioning system includes a converging shape that causes pressure of the air flowing therethrough to decrease and which establishes a negative pressure between the surroundings of the element and the air flowing through the element. A plurality of vents are defined in the element whereby air from a room flows into the element to be mixed with conditioned air in the element before that conditioned air is exhausted into the room. The converging shape of the element causes pressure to vary according to a specific relationship, and each of the vents has a cross sectional area that varies according to the same relationship whereby adjacent vents have different cross sectional areas.
