Publication number: 20120302152Abstract: A universal air pattern controller for use in conjunction with a slot diffuser comprises one or more tubular, elongate universal air pattern controllers mounted with a spring clip to a diffuser frame. The diffuser frame comprises two side frames mounted on opposing sides of a center frame by a spacer, each of the side frames and center frame having flanges which define an elongate slot from which air exits the diffuser. The universal air pattern controller is suitable, without modification or customization, for use in both conventional and linear slot diffuser applications and in non-traditional curved, angled, or specially-shaped diffuser applications.Type: ApplicationFiled: May 27, 2011Publication date: November 29, 2012Inventors: Alfred Theodor Dyck, Jaroslaw Nowak, Adam Pfeiffer

Patent number: 8210308Abstract: An apparatus and method for attenuating the sound generated by a fan powered terminal unit or other equipment in an HVAC (heating, ventilating, and air conditioning) system is described. The apparatus utilizes internal geometry to minimize noise due to air disturbances and aerodynamic effects within the apparatus. Specifically, a silencer is described comprising a casing having an inlet and an outlet; a condensate deflector positioned at the inlet to the casing; at least one baffle being operable to attenuate noise in a gas flowing through the silencer; and an air pathway through the silencer, defined by positions of the condensate deflector and the at least one baffle within the casing. The air pathway is angled or curved to substantially minimize the line-of-sight pathway from the inlet to the outlet.Type: GrantFiled: October 1, 2010Date of Patent: July 3, 2012Assignee: E.H. Price Ltd.Inventors: Jarvis M. Penner, Alfred Theodor Dyck, Brad Curtis Tully, Bogna Gryc

Patent number: 7641125Abstract: A variable air volume ceiling diffuser includes a damper that is raised and lowered by a linkage that is controlled by a duct temperature sensor/actuator and one or more room temperature sensors/actuators. The linkage includes a heating slide movable for the heating mode and a cooling slide movable for the cooling mode. The duct temperature sensor/actuator selects the heating slide for movement by the room temperature sensors/actuators in the heating mode and selects the cooling slide for movement by the room temperature sensors/actuators in the cooling mode. The differential movement between the heating and cooling slides moves a roller that engages a profiled cam surface attached to two lever arms. As the roller moves along the cam surface, the lever arms pivot about their axis of rotation so that the damper moves upward to close the air inlet and downward to open the air inlet.Type: GrantFiled: December 5, 2005Date of Patent: January 5, 2010Assignee: E.H.

Patent number: 7243556Abstract: An airflow sensor for use in a conduit. The sensor comprises stacked first, second and third portions positioned, in use, in the conduit to define a hub and a plurality of tubes. The hub is centrally disposed in the conduit and has first and second interior chambers, a streamlined upstream-facing surface, a downstream-facing surface and a sidewall connecting said upstream and downstream facing surfaces, said sidewall having defined therein one or more static pressure ports through which the first chamber communicates with the conduit interior. The tubes extend radially from the hub, transverse to the flow. Each tube has a streamlined upstream-facing surface having defined therein one or more total pressure ports; a downstream-facing surface; and an interior passage communicating with the second chamber and communicating with the conduit interior through said total pressure ports. Each static pressure port is located downstream from a respective tube.Type: GrantFiled: April 13, 2006Date of Patent: July 17, 2007Assignee: E.H. Price LimitedInventors: Bogna Gryc, Alfred Theodor Dyck

Patent number: 6237426Abstract: An multi-point, center-averaging airflow sensor comprises a plurality of upstream airflow sensing tubes extending radially from a central hub having a total pressure averaging chamber and a static pressure averaging chamber. The airflow sensing tubes are each provided with at least one total pressure port located inwardly of the outer end of the tubes to minimize error caused by total pressure measurements taken near the inner walls of the conduit in which the sensor is installed. The sensor has static pressure ports located in the side surface of the hub which are shielded from upstream air flow by the tubes and which are preferably at least partially shielded from damper back pressure by notched reinforcing blades provided along the length of the airflow sensing tubes.Type: GrantFiled: February 12, 1999Date of Patent: May 29, 2001Assignee: E.H.
