A middle air duct support member and an air conditioner provided. The middle air duct support member has an annular first support portion and an annular second support portion arranged at an axial end of the first support portion. The second support portion and the first support portion are manufactured separately.

A universal control board for high-rise buildings is provided. The universal control board provides a communication system that operatively associates low voltage loading, including a WIFI thermostat application, with line voltage equipment for providing energy savings, humidification, dehumidification, UV lighting and multiple fan applications in high-rise buildings.

An environmental control system includes: a wind blower which blows wind toward a subject; and a control apparatus which obtains at least one time included in a scheduled wake-up time of the subject, a scheduled go-to-bed time of the subject, a sunrise time, and a sunset time, and switches control on the wind blower at the at least one time obtained.

A luminaire includes a luminaire control circuit and a disinfection light source to emit a disinfection light in an ultraviolet (UV) band for disinfecting a vicinity of a space of a target pathogen that is exposed to the disinfection light. The UV band is 200 nanometers (nm) to 230 nm wavelength. The luminaire initiates a dose cycle of a vicinity in which the disinfection light source emits the disinfection light continuously or during a plurality of periods of a dose cycle from the disinfection light source by recording a beginning time of the dose cycle. The luminaire controls, via a driver circuit, the disinfection light source over the dose cycle to emit the disinfection light continuously or during the plurality of periods for disinfecting the vicinity to substantially obtain a target pathogen UV radiation level and restrict a total UV radiation threshold exposure level by a UV radiation threshold limit.

A lighting fixture has an extruded aluminum housing, at least one light source mechanically supported by the extruded aluminum housing, and at least one copper pipe thermally coupled to the extruded aluminum housing to carry a fluid coolant. During operation of the lighting fixture, the fluid coolant flowing through the at least one copper pipe extracts heat generated by the lighting fixture, and the fluid coolant does not contact the extruded aluminum housing. In one example, a copper fluid coolant circuit is thermally coupled to the housing to contain the fluid coolant, and the lighting fixture does not contain any internal seals or internal O-rings for the fluid coolant.

The present disclosure discloses an all-in-one evaporative cooler. The all-in-one evaporative cooler comprises a fan with an air duct and a humidifier with water vapor outlets, wherein the water vapor outlets are communicated with the air duct, the humidifier and the fan are detachably connected, and the fan and the humidifier can respectively independently work after separated. The all-in-one evaporative cooler provided by the present disclosure simultaneously has three functions, namely a humidifying function, a blowing function and a cooling function, and is formed by assembling the humidifier and the fan which can respectively independently work. The independent humidifier and the independent fan have a small size so as to be convenient to carry, and a combination of the humidifier and the fan also has a small size so that arrangement, carrying and function selection are convenient and the diversified requirements of users can be met.

A combined ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and a connector assembly. In an installed position, the system is installed above a ceiling of a room of building structure (e.g., a residence or workplace) to provide ventilation for the room. The system couples a light fixture to ventilation assembly below the ceiling. In the installed position, an air flow cavity is defined between the light fixture and the ceiling, where the cavity allows for air flow around the light fixture and into the ventilation assembly for eventual exhaust beyond the room in which the system is installed. The cavity includes a first critical distance that is sized according to operating parameters of a blower of the ventilation assembly to provide an adequate flow rate of intake air and to provide acceptable sound levels during operation of the system.

A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

Present embodiments relate to a heating, ventilation, air conditioning (“HVAC”) system which is used in both fixed and mobile structures, and which has a luminaire disposed in the HVAC to provide illumination therefrom. The luminaire may be a single continuously on light or it may be a flashing light with one or more patterns. The light may emit a single color or multiple colors. The light may also have a flashing sequence which corresponds to audio. The light may be wired to a switch and/or may be controlled by a smart device in wireless communication with the HVAC system.

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.
