Disclosed is an air conditioner, and more particularly, to an air conditioner having an airflow guide to make the flow of discharged air uniform. An air conditioner comprising a housing having a suction port and a discharge port, a heat exchanger arranged inside the housing, a blower fan configured to suck in air through the suction port, force the air to be subject to heat exchange with the heat exchanger, and discharge the heat-exchanged air through the discharge port, a first blade pivotally arranged to open or close the discharge port and having a first face and a second face opposite of the first face, a first flow path formed between the discharge port and the first face, a second flow path formed between the discharge port and the second face, a second blade movably installed inside the housing and a third blade formed to protrude from the second blade to guide air to the first flow path and the second flow path.

An air guide for a ceiling-type air conditioner is applied to the ceiling-type air conditioner comprising: an indoor unit having a heat exchanger and a blower embedded therein, and having a plurality of blowing passages for discharging, to the outside, air which has passed through the heat exchanger; a plurality of inlets for receiving the air discharged through the plurality of blowing passages; and a discharge panel having an inner space, of which at least a portion communicates with the plurality of inlets, and a ring or arc-shaped opening for discharging, into a room, air which has flowed into the inner space. The air guide includes: at least two partition parts formed in parallel to the radial direction of the opening, and dividing the inner space in the circumferential direction; and a curved part connecting the at least two partition parts, and formed in an arc shape, and is detachably inserted into the inside of the opening from the outside of the opening.

A vortex generator for installation in a passage defined by heating, ventilating, and air conditioning (HVAC) equipment is configured to mix air flow through the passage. The vortex generator includes a proximal end configured to extend from a support defining the passage. The proximal end includes a first width dimension configured to extend transverse to a flow direction through the passage. The vortex generator includes a distal end opposing the proximal end. The distal end includes a second width dimension configured to extend transverse to the flow direction through the passage, where the second width dimension is greater than the first width dimension. The vortex generator includes a body extending from the proximal end to the distal end. The body includes a third width dimension configured to extend transverse to the flow direction through the passage, where the third width dimension is less than the second width dimension.

A blower assembly for a heating, ventilation, and/or air conditioning (HVAC) system includes a centrifugal fan having a fan wheel. A plurality of blades are coupled to the fan wheel at an inner blade boundary and extend radially to an outer blade boundary. The blower assembly includes a first housing panel and a second housing panel disposed on opposite sides of the centrifugal fan and extending transverse to the centrifugal fan. The blower assembly includes a wall extending between the first housing panel and the second housing panel and a flange extending from the wall at a vertex. The flange extends outwardly from the wall. A first radial distance from the vertex to the outer blade boundary is between 4 percent and 20 percent of a second radial distance from a rotational axis of the centrifugal fan to the outer blade boundary.

A system provides warm, humidified gas to a patient via a patient interface. Horizontal connections can be used between the humidification chamber and conduit. To reduce the likelihood of condensate flowing back to the humidification chamber, or dead space or gases recirculation regions occurring within the gases flow path, a raised portion is positioned inside of the flow path to improve flow characteristics and to provide a barrier for condensate back flow. The raised portion also reduces the amount of condensate that is formed in the system and provides better flow characteristics for sensing purposes.

A manufacturing fixture having an integrated diffuser for diffusing conditioned air into an industrial workspace is disclosed. The fixture includes an elevated platform having an air inlet and a diffuser deck mounted below the platform and disposed below the air inlet. The diffuser deck includes a set of louver plates arranged in a vertical stack. Each of the louver plates of the set has a top surface and an opening wherein the opening of each subsequent louver plate below the uppermost louver plate has an area less than the area of the louver plate directly above. The top surface of each louver plate is angled downward from the opening.

An indoor unit according to the present invention includes: an air-sending portion, which includes a casing having a rectangular air outlet and accommodating an impeller including a plurality of blades; a heat exchanger, which is configured to exchange heat with gas sent from the air-sending portion; and a guide portion, which includes an upper guide defining a passage for the gas and being arranged between an upper edge portion of the air outlet and an upper end portion of the heat exchanger and a lower guide defining a passage for the gas and being arranged between a lower edge portion of the air outlet and a lower end portion of the heat exchanger, and is open at side regions of the guide portion.

Embodiments of the present technology are directed to air treatment reactor modules, and associated systems and devices. An exemplary reactor module can include a housing, an ultraviolet (UV) light source disposed within the housing, and a plurality of hollow elongate conduits disposed within the housing and peripheral to the UV light source. The UV light source and individual conduits can extend in a lateral direction perpendicular to the direction of air flow through the reactor module. The conduits can include a plurality of holes and be at least partially coated with a photocatalytic material. The housing can have an inner surface comprising a reflective material that, in operation, reflects UV light emitted from the UV light source.

The present disclosure relates to louvers for enabling an air passage between an outside and an inside. More particularly, the present disclosure relates to louvers enabling said air passage while minimizing rain ingress towards an interior and minimizing noise produced in the interior. The present disclosure further relates to wind turbines including said louvers.

An air conditioner system including a sleeping enclosure defining a sleeping space into which conditioned air is adapted to be delivered from one end or side of the sleeping space in a manner which maximizes contact between conditioned air and a person or persons in the sleeping space, the sleeping space including an upper air pervious section; and a lower relatively air impervious section adapted to surround a bed in the sleeping space and configured to minimize passage of the conditioned air from the sleeping space through the pervious section or other leakage paths; and an air conditioner unit for generating a conditioned air flow, wherein the impervious section extends to a height above the sleeping surface of the bed at the end or side of the bed opposed to said end or side sufficient to contain the conditioned air as it moves towards and returns from the opposite end or side of the sleeping space, and wherein the impervious section extends to a sufficiently increased height above the sleeping surface at the opposite end or side to allow the direction of air flow to reverse towards said one end or side without substantial loss of conditioned air through the pervious section.
