Abstract: A terminal unit for a heating, ventilation, and air conditioning (HVAC) system includes a housing defining a plenum and having a first panel and a second panel disposed opposite each other. The first panel has a first outlet opening and a second outlet opening, and the second panel has a first inlet opening configured to receive a first air flow and a second inlet opening configured to receive a second air flow. The terminal unit includes a sound attenuator including an inlet configured to receive the first air flow and an outlet configured to discharge the first air flow into the housing via the first inlet opening. The terminal unit further includes first and second blowers. The first blower is configured to discharge air from the plenum via the first outlet opening, and the second blower is configured to discharge air from the plenum via the second outlet opening.

Abstract: A controller of a heating, ventilation, and/or air conditioning (HVAC) system includes a printed circuit board (PCB). The PCB includes processing circuitry disposed on the PCB and configured to receive a control input, and to determine a motor control output based on the control input. A transformer disposed on the PCB is configured to receive input electrical power at a line voltage, and to generate electrical power at a step-down voltage using the input electrical power.

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.
