A combination axial fan and LED lighting system. 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. The invention includes a vented mechanical equipment casing configured to include an opening to direct a portion of the air exiting the fan cavity into an equipment chamber housing the mechanical equipment and configured to direct the air to encounter the mechanical equipment and operate to reduce the temperature of the equipment.

The present invention relates to an electrical device provided in or attached to an air duct. The electrical device comprises a housing and an electrical body attached to the housing which extends at least partially into the housing and is adapted to connect a power source to an electrical element. The housing is provided with a passage for allowing air to flow between an end of the housing to be turned towards a room of the building and an end of the housing to be turned towards the air duct and for allowing air to flow in the space between an inner housing side and an outer side of the electrical body.

A lamp includes an air supply and a lighting module. The air supply includes an air blower and an annular housing, the annular housing defines an annular region and has an inner ring surface, an outer ring surface, a first end surface and a second end surface which are connected with the inner ring surface and the outer ring surface and face away from each other. The lighting module is disposed at a side of the annular housing which is close to the first end surface and is located within a projection range of the annular region at the side, and the lighting module emits light rays towards the side faced by the first end surface.

A building automation system (BAS) platform includes one or more processors configured to provide an operating environment for developing and executing a plurality of building automation and control microservices. At least one of the plurality of building automation and control microservices is configured to receive live data from remote building equipment and provide control signals to the remote building equipment. The BAS platform further includes one or more application programming interfaces configured to interact with third-party building automation and control applications that run within the operating environment.

Positive air pressure is applied on a ventral side of a plant canopy and negative air pressure is applied on a dorsal side of the plant canopy. By this arrangement, the negative air pressure draws air supplied by the positive air pressure on the ventral side of the plant canopy across the plant canopy past the dorsal side of the plant canopy to withdraw heat from the plant canopy, for example, from an agricultural lighting system and/or humidity from plant respiration in a controlled indoor environment.

Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include one or more UV-C light sources which irradiate contaminants as air flows through the UV-C unit. The UV-C unit is mounted on either a universal mounting mechanism or a mobile support unit to provide mobility to the UV-C unit.

Device for treating air and/or surfaces with treatment substance for disinfecting, can include a blower for sucking and blowing air, at least one conveying device for conveying the treatment substance, and at least one feed nozzle for feeding the treatment substance, wherein the feed nozzle is connectable to the conveying device via a connection line. The at least one feed nozzle can be arranged in the air flow of the blower, wherein the at least an end of a feed nozzle is removable and can also be arranged at a distance from the device, and can be connected to a ventilation duct of a ventilation and/or air-conditioning system of an environment. Additionally or alternatively, at least one further feed nozzle, which is connected or connectable to the conveying device via a connecting line, can be connected to a ventilation duct of a ventilation and/or air-conditioning system of the environment.

The present disclosure provides a rotary dancing aromatherapy humidifier, which includes a main machine body of the humidifier, a control circuit board arranged inside the main machine body of the humidifier, an atomizing plate sub-assembly and a rotary driving mechanism. The main machine body of the humidifier includes a water tank body, a rotating pattern ring with a grid pattern is located on the outside of the water tank body, a grid tube on the outside of the rotating pattern ring, and also includes a rotating seat for installing the rotating pattern ring; the rotating driving mechanism drives the rotating seat and the rotating pattern ring to rotate axially, and the atomizing plate sub-assembly and the rotating driving mechanism are electrically connected with the control circuit board.

A protective seal removably fits onto the top of coil fins of a condenser unit for an air conditioning system. The protective seal has a U-shaped cross-sectional configuration that allows the protective seal to fit over and completely cover the entire top edges of the coil fins and to extend partially down the front and rear sides of the coil fins to cover an upper portion of the front and rear sides of the coil fins. The protective seal is further structured to follow the contour of the top edges of the coil fins around all sides of the condenser unit to protect the top edges and the upper portion of the front and rear sides of the coil fins when the top lid of the condenser housing is both hinged open and closed.

A wall- or surface-mounted light fixture with a housing containing one or more external visible light sources to illuminate the space where the light fixture is mounted, one or more UV emitters inside or outside the housing to destroy bacteria and pathogens, and one or more fans inside the housing that recirculate the air in a space and subject the air to the UV radiation inside the housing, destroying bacteria and pathogens in the air passing though the housing.
