The present disclosure is directed to a sunshade system that monitors a position of the sun and adjusts a position of a frame and/or blades based on a position of the sun. For example, a heating, ventilation, and air conditioning (HVAC) unit of an HVAC system may be exposed to adverse, external weather conditions, such as sunlight, which may heat up components of the HVAC unit and decrease an efficiency of the HVAC system. Accordingly, a control system of the sunshade system may monitor the position of the sun and adjust the position of the frame and/or the blades to provide adequate shading for the HVAC unit.

Systems and methods for sunshade adjustment

A nozzle assembly for a fan unit includes an inner nozzle having a tapered outer diameter and a flow path radially inward from the tapered outer diameter with respect to a longitudinal axis of the nozzle assembly. The flow path is configured to guide a fluid flow and to expel the fluid flow through an inner outlet of the inner nozzle to a surrounding environment. The nozzle assembly also includes an outer nozzle disposed radially outward from the inner nozzle with respect to the longitudinal axis. The outer nozzle and the tapered outer diameter of the inner nozzle define an annular flow path therebetween. The annular flow path is configured to guide the fluid flow and to expel the fluid flow to the surrounding environment through an outer outlet of the outer nozzle. A cross-sectional area of the outer outlet is adjustable via movement of the inner nozzle, the outer nozzle, or both along the longitudinal axis of the nozzle assembly.

A louver blade for a louver assembly includes a first section, a second section extending from the first section and including a crest of the louver blade, an extension extending from the second section to form a recess between the extension and the second section, and a protrusion extending from the second section toward the extension and configured to facilitate retention of the particles within the recess. The extension is configured guide particles into the recess in an installed configuration of the louver blade with the louver assembly.

A damper of a heating, ventilation, and/or air conditioning (HVAC) system includes a crank configured to rotate about an axis of a shaft relative to a support, a reset arm configured to rotate about the axis of the shaft relative to the support, a spring coupled to the crank and the reset arm, and a fuse link configured to be coupled to the reset arm and the support in a set configuration and to release the reset arm from the support in response to a temperature exceeding a threshold temperature. The crank and the reset arm are configured to rotate away from the support in a first circumferential direction toward a closed configuration in response to the fuse link releasing the reset arm from the support. A spring force of the spring is configured to increase to enable the reset arm to rotate in a second circumferential direction opposite to the first circumferential direction beyond the set configuration and into a reset configuration.

Damper assembly of a heating, ventilation, and/or air conditioning (HVAC) system

A firestat for providing an output for controlling an opening and closing of a fire/smoke damper. The firestat includes a fire/smoke damper test switch and an actuator configured to depress the fire/smoke damper test switch. The firestat is further configured to release the fire/smoke damper test switch in response to a depressing force applied to the actuator, wherein melting or other damage to the actuator causes a release of the test switch.

Damper test switch fail-safe actuator

A cam assembly for selectively contacting an end-of-stroke damper position switch. The cam assembly includes a first cam that is rotatable about a first axis, and a position lever that is connected to and rotates with the cam assembly. The position lever is configured to be connected to an opening and closing mechanism of the damper and the cam assembly is adjustable to contact a first end-of-stroke damper position switch at the end-of-stroke of the opening and closing mechanism of the damper regardless of the position of the lever.

Adjustable cam assembly for damper position feedback

A resetting element for transmitting resetting force to a thermal switch. The resetting element includes a first end and an elastic element configured to transmit a force received at the first end to the reset switch of the thermal switch, wherein the elastic element is prevents damage to the thermal switch by decreasing the force transmitted to the reset switch from the first end.

Thermal sensor reset rod for thermal sensor

A damper to manage air flow includes a housing that defines a passageway through which the air flow is directed. The damper includes a ring having a flat surface that terminates at an outside dimension and at an inside dimension, where the outside dimension is disposed to fit within the passageway and is pivotably rotatable along an axis that bisects the passageway. The damper also includes a disc having a flat surface that terminates at an outside dimension that is nested within the inside dimension of the ring in a gimballed relationship and is pivotably rotatable along the axis. The damper further includes an actuator coupled to the ring and the disc, where the actuator is configured to separately rotate each of the ring and the disc about the axis.

Damper assembly

An adjustable neck for a vent cap includes a housing having a mount and a cylindrical body, where the cylindrical body includes an inner surface. The adjustable neck also includes adjustable straps arranged to form an adjustable inner diametrical surface disposed radially inward from the cylindrical body of the housing, relative to a central axis of the adjustable neck. The adjustable inner diametrical surface is configured to engage an outer pipe surface. The adjustable straps are coupled to the inner surface of the cylindrical body. The adjustable neck also includes legs coupled to the adjustable straps and to the mount, where the cylindrical body is configured to be rotated relative to the mount and the legs to adjust a dimension of the adjustable inner diametrical surface to correspond to the outer pipe surface.

Rotary adjustable neck for gas vent cap

The present disclosure relates to a power transmission system for actuating a damper. The power transmission system includes an input shaft configured to rotate about a first axis and a first input dog rotatably coupled to the input shaft. The power transmission system also includes a second input dog coupled to the first input dog. The first input dog includes a first arrangement of teeth extending along a second axis and the second input dog includes a second arrangement of teeth extending along the second axis. The first input dog and the second input dog are configured to move axially along the second axis to enable engagement and disengagement of the first and second input dogs with first and second output dogs, respectively. The first and second output dogs are configured to engage with respective damper blades of the damper.
