An object of the present technology is to provide a technology that enables control of an odor. The present technology provides an odor presentation module including a first opening that first airflow containing an odor exits, and a second opening that second airflow exits, in which the first opening and the second opening are provided so that movement of the first airflow exiting the first opening is able to be controlled by the second airflow. The present technology also provides an odor presentation device and an odor presentation system including the odor presentation module. Further, the present technology provides an odor presentation method including a first airflow generation step of emitting first airflow containing an odor from a first opening, and a second airflow generation step of generating second airflow exiting a second opening or second airflow entering the second opening, in which movement of the first airflow exiting the first opening is controlled by the second airflow.

A system and a method are provided to create an indoor thermal environment based on impinging jet ventilation (IJV) and ductless personalized ventilation (DPV), the system includes an IJV duct installed on a wall of a room and a DPV device installed on a table. An air inlet of the IJV duct is connected to an air conditioning system and an air outlet of the IJV duct is close to ground. An upper duct and a lower duct of the DPV device are disposed on two opposite sides of a tabletop, the upper duct is provided with an air supply panel, the lower duct is provided with a duct fan with an air supply volume being adjustable, and the duct fan is configured to send air absorbed from a ground air lake to a user’s face area through the air supply panel of the upper duct.

A system including a housing that at least partially defines a cavity therein. The housing includes one or more apertures to permit air to circulate between the cavity and an external volume that is outside the housing. The system includes one or more fans for circulating the air through the cavity via the apertures. The system may also include one or more disinfecting devices for at least partially disinfecting the air moving through the cavity.

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
