    Abstract: An actuator is usable in a damping system, which may be a component of an airside system, waterside system, building management system, or HVAC system. The actuator is coupled to a damper and may open and close the damper. The damper selectively seals a duct to prevent spreading of gas, smoke, or fire within a building. The actuator includes a gear that rotates as the damper is opened and closed. A cluster pinion is coupled to the gear and rotates with the gear. A locker is rotatably coupled to a stopper and has a range of motion limited by the stopper. The stopper includes a rib extending outwardly and limiting the range of motion of the locker. The rib is configured to deform at a temperature exceeding a threshold. A spring is coupled to the locker and biasing the locker against the rib.

    Abstract: A hood assembly for a heating, ventilation, and air conditioning (HVAC) unit includes a top panel comprising a first panel portion and a second panel portion adjustably coupled to one another, wherein the top panel is configured to rotatably couple to a housing of the HVAC unit. The hood assembly further includes a filter frame rotatably coupled to the top panel, wherein the filter frame is configured to support at least one filter. The hood assembly is adjustable between a collapsed configuration and a deployed configuration, the first panel portion and the second panel portion are configured to translate relative to one another during transition of the hood assembly between the collapsed configuration and the deployed configuration, and the top panel is configured to contain the filter frame within the housing in the collapsed configuration.

    Abstract: A heating, ventilation, and/or air conditioning (HVAC) packaged unit includes a first refrigerant circuit component configured to change a temperature or a pressure of a refrigerant flowing through the first refrigerant circuit component and a second refrigerant circuit component configured to change a temperature or a pressure of the refrigerant flowing through the second refrigerant circuit component. The first and the second refrigerant circuit components are within a common refrigerant circuit that is disposed within a common support structure. The HVAC packaged unit also includes an interconnection conduit having a length formed from aluminum, a first end segment coupled to a first end of the length, and a second end segment coupled to a second end of the length. The first end segment and the second end segment are each formed from copper, and the interconnection conduit extends between the first refrigerant circuit component and the second refrigerant circuit component.
