  • Patent number: 8453790
    Abstract: A low-profile, compact fan coil ceiling unit with closely coupled silencers includes a heating and cooling section, a closely coupled inlet silencer, and a closely coupled outlet silencer. The inlet silencer has a rectangular housing with a downwardly facing entry opening and a side facing exit opening attached to the inlet end opening of the heating and cooling section. The outlet silencer has a rectangular housing with a downwardly facing exit opening and a side facing entry opening attached to the outlet end opening of the heating and cooling section. Baffles to control the flow of air and reduce noise in the inlet silencer and the outlet silencer are provided.

  • Publication number: 20120270493
    Abstract: A packless silencer for a Venturi control valve being a generally rectangular enclosed housing formed by four side walls and having an intake opening and a discharge opening. Four perforated baffles for each of the side walls are positioned inside of the housing, extend the length of the housing and are offset from the side walls to create an empty baffle space between the perforated baffles and the side walls the ends of the baffle space are covered by end caps.

  • Patent number: 8210308
    Abstract: 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.

  • Patent number: 7243556
    Abstract: 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.

  • Patent number: 6237426
    Abstract: 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.
