System and method to reduce risk of patient infections (HAI), using operating rooms (chambers) equipped with suitable automatic airborne sterilizing agent generators, sensors, mechanisms, automatic air control devices, and laminar flow devices. After suitable safety checks, the system isolates the interior air from external air, and activates an air phase anti-microbial agent generator, filling the room with an air-phase anti-microbial agent. After sterilization, the invention deactivates the generator then restores the connection to outside sterilized air. The chamber also comprises an intelligent platform comprising video cameras, and computer vision systems configured to identify humans and medical supplies, read optical tags, and correlate recognized objects with RFID tag data. The intelligent platform can be configured to automatically detect and warn on conditions associated with a high risk of HAI, optimize the sterility of the chamber, automatically detect other operating room issues, and interface with outside computerized medical databases and facilities networks.

This invention relates to an indoor lighting and climate system, comprising a plurality of lighting units (1) arranged in a dispersed manner in a room (2) and a control unit (3) arranged to control the operation of the lighting units (1) in relation to pre-set climate settings and input signals from at least one temperature sensor (4), wherein each of said 5 lighting units (1) include a cup shaped housing (100) with an opening (101), a lamp attachment (102) for a lamp (103), an open inside space (105) between said lamp (103) and said cup shaped housing (100), and a fan (104) arranged to produce a forced air flow (2) in said space (105), characterized in that a circumferentially extending inner dividing wall member (107) is arranged within said cup shaped housing (100), which 10 circumferentially extending dividing wall (107) separates said open inside space (105) from a heat flow channel (106) arranged within said cup shaped housing (100).

A ventilation system includes a ventilation fan with a lamp module, the ventilation fan includes a housing, a base, and a fan module. The base is located below the housing, and the base includes a first flow guiding structure. The fan module is disposed in the housing, and the fan module includes a second flow guiding structure.

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.

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.

Disclosed herein is a luminaire chilled beam that can incorporate lighting into a chilled beam unit without affecting the capacity, performance, or dimensions of the chilled beam. The luminaire chilled beam can include a pressure chamber configured to receive primary air through a primary air inlet. A nozzle plate in a lower portion of the pressure chamber can allow the primary air to be expelled from the pressure chamber and thereby cause an induction of air from an external setting through an induction face and into an induction chamber. A water coil can be configured to treat the induced air within the induction chamber. The induced air and the primary air can be expelled from the induction chamber and into the setting through discharge channels. The luminaire chilled beam can further include a luminaire assembly including a luminaire positioned between the induction face and the discharge channel at the lower portion of the induction chamber, the luminaire configured to illuminate the external setting.

A lasting effect essential oil supply aromatherapy humidifier comprises: a water storage bucket is located the top of a seat, the inner bottom of the bucket is provided with an atomizer, an inner cover shell is covered on the water storage bucket, and the outermost layer is covered with an outer cover shell. The essential oil releaser is located on the water storage bucket, and the essential oil releaser has a placed seat, and a threaded connection port upwards on one side of for supplying an opening of the essential oil bottle to be butted, and another side is located with a control amount release opening which is sunk low into the water storage bucket. The essential oil can be slowly released into the water storage bucket for an extended period for perfume fusion, the application can produce a consistent and elegant light fragrance spray, which is released into the air. The present invention allows users to conveniently add essential oils without frequently opening the aromatherapy humidifier, and at the same time, which can prolong the use time of the aromatherapy, and obtain the effects of refreshing, reinvigorating, and physical and mental comfort.

According to an aspect of this disclosure, a ventilation and lighting system including a main housing having an inlet opening and a discharge opening, a blower and motor assembly disposed within a housing and operable to move air through the inlet and outlet, a grille configured to be located at the inlet opening, the grille having a cavity and a plate defining a plurality of apertures through which air may move, and one or more lighting elements arranged within the cavity and an optical component covering the cavity. The system is arranged such that light developed by the one or more lighting elements mixes within the cavity and transmits through the optical component covering the cavity, and the system further includes a controller that coordinates operation of the blower and motor assembly and the one or more lighting elements from a remote location.
