Abstract
A terminal unit for a heating, ventilation, and/or air conditioning (HVAC) system may include a housing defining a mixing chamber. The mixing chamber may have a primary air inlet, a plenum air inlet, and a mixed air outlet, and mix a primary air flow from the primary air inlet with a plenum air flow from the plenum air inlet to form a mixed air flow that is output through the mixed air outlet to a conditioned space. The terminal unit may also include a panel adjustably coupled to the housing to adjustably occlude the plenum air inlet. The terminal unit may also include an actuator coupled to the housing and the panel to move the panel and adjust a size of an air flow path corresponding to the plenum air inlet.
Claims12
A terminal unit for a heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a housing defining a mixing chamber including a primary air inlet, a plenum air inlet, and a mixed air outlet, wherein the mixing chamber is configured to mix a primary air flow from the primary air inlet with a plenum air flow from the plenum air inlet to form a mixed air flow that is output through the mixed air outlet to a conditioned space;
- a panel adjustably coupled to the housing, wherein the panel is configured to adjustably occlude the plenum air inlet;
- an actuator coupled to the housing and the panel, wherein the actuator is configured to move the panel to adjust a size of an air flow path corresponding to the plenum air inlet;
- a controller configured to determine a position of the panel corresponding to a reduced noise output of the terminal unit, wherein the controller is configured to determine the position of the panel corresponding to the reduced noise output of the terminal unit based on measured feedback;
- and
- a sensor configured to measure a static air pressure of the primary air flow, wherein the measured feedback comprises the static air pressure.
A terminal unit for a heating, ventilation, and/or air conditioning (HVAC) system, comprising:
- a housing defining a mixing chamber including a primary air inlet, a plenum air inlet, and a mixed air outlet, wherein the mixing chamber is configured to mix a primary air flow from the primary air inlet with a plenum air flow from the plenum air inlet to form a mixed air flow that is output through the mixed air outlet to a conditioned space;
- a panel adjustably coupled to the housing, wherein the panel is configured to adjustably occlude the plenum air inlet;
- an actuator coupled to the housing and the panel, wherein the actuator is configured to move the panel to adjust a size of an air flow path corresponding to the plenum air inlet;
- and
- a controller configured to determine a position of the panel corresponding to a reduced noise output of the terminal unit,
- wherein the reduced noise output of the terminal unit comprises a minimized summation of a first noise and a second noise, wherein the first noise is associated with the primary air flow and the second noise is associated with the plenum air flow, wherein the plenum air flow is non-zero.
