Abstract
An enclosure for an actuator of an HVAC unit includes a hollow member with an inner shell, an outer shell, and an insulation layer disposed between the inner shell and the outer shell. A cavity within the inner shell operates to receive an actuator. An exterior surface of the hollow member has curvilinear shape configured to limit resistance to airflow over the exterior surface. A base of the enclosure is connected to a first end of the hollow member and a cover is detachably coupled to a second end of the hollow member opposite the first end.
Claims20
An enclosure for an actuator of an HVAC unit, the enclosure comprising:
- a hollow member comprising an inner shell, an outer shell, and an insulation layer disposed between the inner shell and the outer shell;
- a cavity within the inner shell configured to receive an actuator;
- an exterior surface of the hollow member having curvilinear shape configured to limit resistance to airflow over the exterior surface;
- a base connected to a first end of the hollow member;
- and
- a cover detachably coupled to a second end of the hollow member opposite the first end.
A ventilation system, comprising:
- a damper configured to be opened and closed by an actuator to control airflow through a flow path of the ventilation system;
- an enclosure mounted on the damper;
- a hollow member of the enclosure defining a cavity configured to receive the actuator;
- a exterior surface of the hollow member having a curvilinear shape configured to limit resistance to the airflow passing over the enclosure;
- a base connected to a first end of the hollow member;
- and
- a cover detachably coupled to a second end of the hollow member opposite the first end.
A tunnel ventilation system, comprising:
- an airflow path for ventilation of an interior space;
- a damper configured to transition between an open configuration and a closed configuration to control airflow through the airflow path;
- an actuator configured to transition the damper between the open configuration and the closed configuration via a mechanical operator directly or indirectly coupled to the damper;
- an enclosure mounted on the damper and positioned within the airflow path;
- a hollow member of the enclosure formed from an inner shell, an outer shell, and an insulation layer disposed between the inner shell and the outer shell, wherein the hollow member defines a cavity in which the actuator is disposed;
- a exterior surface of the hollow member having a curvilinear shape that is configured to limit resistance to the airflow passing over the enclosure;
- a base connected to a first end of the hollow member;
- and
- a cover detachably coupled to a second end of the hollow member opposite the first end, wherein the cover comprises a port through which the mechanical operator extends.
