An air conditioner includes a housing including an inlet and an outlet, a heat exchanger arranged inside the housing to exchange heat with air sucked through the inlet, a fan configured to move air, which is heat-exchanged with the heat exchanger, to be discharged through the outlet, a motor configured to generate a rotational force, and a blade unit configured to guide air discharged to the outlet.

A ventilation fan unit for causing air flow with respect to a room having a ceiling, the room designed for occupancy by a person. The fan unit has a fan unit housing mounted in the ceiling and having an air vent on a room facing surface of the fan unit housing for drawing air from or delivering air to the room. A replaceable panel is provided with a first surface and a second surface, the replaceable panel is removably attachable with the room facing surface of the fan unit housing by way of coupling between the replaceable panel and the fan unit housing so that the replaceable panel can be removed and replaced with another replaceable panel attachable to the fan unit housing by way of the coupling. The replaceable panel, when attached to the fan unit housing, is positioned to obstruct the person's view of the air vent while allowing flow of air therethrough

An air purifying bed tent is disclosed, having a tent made from a semipermeable material suspended over a raised platform, thereby creating an enclosure for a user to be inside. An air purifying device is connected to the top of the tent, letting purified air into the enclosure and creating a local clean air zone for users. The positive pressure difference building up in the enclosure from the constantly added clean air forces clean air out through a plurality of openings, primarily through creases in the semipermeable material around the raised platform. Should the skirting be completely sealed, the semipermeable material will let out the pure air to a higher degree, ensuring a stable and easy touse operation.

An exemplary embodiment of the present disclosure provides a localized heating, ventilation, or air conditioning (HVAC) system comprising a moveable air delivery system comprising. The moveable air delivery system further comprising an air inlet configured to receive air and an air outlet configured to output the air into a space. The localized HVAC further comprising a movement system configured to move the air outlet in a generally planar manner. The movement system further comprising an air delivery support system configured to support the air outlet, the air delivery support system configured to move the air outlet in an air delivery plane.

A ceiling module for the construction of a clean room cell, where the ceiling module includes at least a module support for arrangement on and connection to a support structure, a technical device including at least one filter unit, and a ceiling support which is spaced apart from the module support such that a technical space is formed between the ceiling support and the module support, wherein the technical device is arranged inside the technical space.

An impeller includes a main plate, an annular side plate and blades. The blades each have: an inner circumferential end; an outer circumferential end; a sirocco blade portion formed as a forward-swept blade portion, and having an outlet angle that is greater than 90 degrees; and a turbo blade portion formed as a swept-back blade portion and including the inner circumferential end. The blades include a first blade portion and a second blade portion that are provided on respective sides of the main plate. The impeller including a region in which a first inter-blade distance is greater than a second inter-blade distance, where an inlet-blade distance is a distance between any adjacent two of the blades in the circumferential direction, the first inter-blade distance is the inter-blade distance of the first blade portion, and the second inter-blade distance is the inter-blade distance of the second blade portion.

A temperature destratification assembly can include an outer housing. An impeller can be positioned within the outer housing between the inlet and outlet of the outer housing. The impeller can have an impeller hub and a plurality of impeller blades extending radially outward from the impeller hub. The assembly can include an impeller motor configured to rotate the impeller blades about an axis of rotation. A stator can be positioned within the outer housing between the impeller and the outlet of the outer housing. The stator can include a plurality of vanes. The stator vanes can include an upstream edge at the upstream end of the stator, a first surface extending from the upstream edge to the downstream edge of the vane, and a second surface opposite the first surface and extending from the upstream edge to the downstream edge of vane. A plurality of the vanes can have a downstream edge at the outlet of the outer housing.

Extremely lightweight device which hangs from the ceiling by 1 point (2 screws), used for absorbing/pulling in air, smoke and vapors and gets it out to the ceiling duct or window.

Made of 2 extensible sticks, having 1 point of support and 2 points of pushing on the ceiling. The hood (tip of the device) can be rotated/moved in the room 360 degrees, basically anywhere needed for the air extraction.

A device comprising a fin structure, a vent disposed in the fin structure, a cooling coil disposed in the vent, a light disposed in the fin structure and wherein the fin structure is configured to create a Coanda effect for air exiting the vent.

The present technology is generally directed to appliance hubs and related systems and methods. In some embodiments, an appliance hub includes a frame assembly and one or more panel assemblies mounted thereto. Individual panels of the panel assemblies can be removably coupled to the frame. At least some of the panels can include one or more functional components, such as one lighting elements, acoustic controls, speakers, vents, mechanical/electrical/plumbing (“MEP”) components, and/or other devices. Accordingly, the frame assembly can be used to manufacture many differently configured appliance hubs with different arrangements of panels and devices positioned thereon. Further, the ability to remove or partially remove individual panels of the appliance hubs after the appliance hub is installed in a ceiling or other upper portion of a room allows for maintenance of existing devices of the appliance hub and/or replacement of devices or the panels themselves.
