摘要： A dual pressure damper used as an air intake damper in an air intake duct, The intake duct is used for introducing intake air into a room. The dual pressure damper helps maintain a negative air pressure “N” in the room. In particular, the room is used for plant oil extraction. The intake air vents toxic gases from the room and out an exhaust duct. The dual pressure damper includes a low pressure damper blade and a high pressure damper blade. A torsion coil spring includes a long torque arm attached to the low pressure damper blade and a short torque arm attached to the high pressure damper blade. The torque arms are used to open and close the damper blades at different incoming air pressures.

摘要： A damper assembly includes a frame having an inner surface and a protrusion extending inwardly relative to the inner surface, a damper blade coupled to the frame and configured to transition between an open position and a closed position, and a latch coupled to the inner surface of the frame. The latch is configured to deform to facilitate transition of the damper blade between the open position and the closed position and to expand to capture and retain the damper blade in the closed position, the latch includes a tab segment configured to move toward the protrusion during deformation of the latch and to move away from the protrusion during expansion of the latch, and a distal end of the tab segment overlaps with a thickness of the protrusion.

摘要： An air conditioner may provide a a fan housing assembly that moves in the front-rear direction by the operation of an actuator, and the fan housing assembly moves so as to pass through a front outlet arranged on a door assembly to be in a projected state, and the front end of the fan housing assembly protrudes further to the front than the front surface of the door assembly; and through the projected state, may provide conditioned air by a direct air flow to a long-distance target region. The configuration may enable the minimization of interference between the discharged air and the door assembly, and the minimization of flow loss of the discharged air since, when the fan housing assembly is in the projected state, a steering grill is in a state of protruding to the outside of the door assembly by passing through the front outlet.

摘要： Control damper including a body, defining a duct with an axis of blowing, and a control device, including a flap for closing the duct, the flap being movable in rotation with respect to the body about a pivot axis orthogonal to the axis of blowing, means for adjusting a nominal position of the flap, and a return device returning the flap to the nominal position when the flap is moved away from the nominal position. For an improved control, the means for adjusting further includes a shaft pivotally mounted with respect to the body about an axis of adjustment, wherein an angular position of the shaft about the axis of adjustment is adjustable, and at least one control cam limiting movements of the flap between the nominal position and an open position, wherein the return device includes a spring that is tensioned when the flap is in the nominal position.

摘要： A front end of a steering grill from which air is discharged protrudes further than the front surface of a door assembly, and the steering grill is steered by a steering assembly, and thus conditioned air may be provided by a directed air movement to a long-distance target region, and since the front end of the steering grill protrudes further than the front surface of the door assembly, the occurrence of flow resistance as a result of a cabinet assembly or the door assembly interfering with the discharged air may be minimized, and the direction of the steering grill may be instantly changed, by means of steering, from any one direction to another among up, down, left, right, upper left, lower left, upper right, or lower right.

摘要： A damper assembly includes a frame, a damper blade coupled to the frame and configured to transition between an open position and a closed position, and a latch configured to be secured within the damper assembly via a clip portion of the latch. The latch is configured to deform to facilitate transitioning of the damper blade from the open position to the closed position and then to expand to capture and retain the damper blade in the closed position.

摘要： An illustrative damper system includes a damper blade that is configured to be positioned within a duct, such as a bypass duct of an HVAC system. A shaft is in communication with the damper blade, a torsion spring is in communication with the shaft, and a force adjustment mechanism is in communication with the torsion spring. The shaft, the damper blade, and the torsion spring may be configured such that the shaft may affect movement of the damper blade about a rotation axis and the torsion spring may provide a bias force to the shaft for biasing the damper blade toward a desired position (e.g. closed position).

摘要： Embodiments of a door assembly with a door component that can open and close in response to pressure of fluids that flow in a fluid handling system. These embodiments utilize elements to seat and lock the door in position without the need for manual intervention and/or interaction, e.g., by a technician and/or maintenance personnel. However, these elements do not need to support the weight of the door and, thus, provide a more robust and cost effective design to achieve automated and reliable operation necessary for use in fluid handling systems.

摘要： A soffit vent preventing an ingress of air while facilitating egress thereof, including a cylindrical frame containing an internal vent mechanism, which frame is mounted to the external surface of the soffit duct opening. The other end of the soffit vent is mounted on the vent duct. Within the cylindrical frame is an internal vent mechanism, comprising a cross beam defining two interstices, each interstice having a vent flap on the downstream side. A tension means holds the flaps closed, until the pressure within the building is greater than that outdoors, which pressure pushes the flaps open.
