Methods, systems, and devices for monitoring air quality and controlling air purification in an environment are described herein. The method can include receiving from a device a plurality of air quality parameters for the environment and receiving an indication representing a potential change in occupancy in the environment. In response to the indication of a potential change in occupancy, the method can include determining an air quality target that is based at least in part on at least one air quality parameter in the plurality of air quality parameters and the potential change in occupancy. The air quality parameter can be representative of the quality of air to be achieved in the environment for the change in occupancy. The method can include transmitting instructions to control purification in the environment based at least in part on the air quality target.

An integrated air conditioning and elevator system of a building is provided. The system includes an air handling unit having a variable speed fan, a first elevator shaft configured to span a plurality of floors in the building, and a plurality of first dedicated variable speed fans located within the first elevator shaft, wherein one of the plurality of first variable speed fans is located at each of the plurality of floors and configured to fluidly connect the first elevator shaft with the respective floor of the plurality of floors. The variable speed fan of the air handling unit is configured to convey air to or from the first elevator shaft and each of the plurality of first variable speed fans is configured to convey air between the respective floor of the plurality of floors and the first elevator shaft.

A presentation information generation device includes: an air flow calculating unit that acquires ventilation equipment information indicating a state of ventilation equipment in a passenger car, and outputs air flow information regarding an air flow in a car interior of the passenger car by using the ventilation equipment information; a presentation information generating unit that generates and outputs an air flow image indicating a state of the air flow in the passenger car by using the air flow information output by the air flow calculating unit; and a presentation information output unit that causes a presentation device to present the air flow image output from the presentation information generating unit.

The present disclosure relates to an elevator having a function of removing dust adhered to an object aboard, including: a car which provides a boarding space, and in which a pair of air holes disposed in a diagonal direction each other at a same height of an inner space are formed; and a pair of fan modules that generates whirlwind rotating in the inner space of the car by ejecting air traveling from one of the pair of air hoes in a direction away from a center of the inner space of the car and ejecting air traveling from the other of the pair of air hoes in a direction away from the center of the inner space of the car, in which dust adhered to the object aboard inside the car is separated from the object aboard by the whirlwind generated inside the car.

A presentation information generation device includes: a recommended position calculating unit that acquires ventilation equipment information indicating a state of ventilation equipment in a passenger car and outputs recommended position information of a passenger by using the ventilation equipment information; a presentation information generating unit that generates and outputs recommended position presenting information indicating a recommended position of the passenger in the passenger car by using the recommended position information output by the recommended position calculating unit; and a presentation information output unit that outputs, to a presentation device, the recommended position presenting information generated by the presentation information generating unit.

A protector (200) for an elevator car (102) includes a protective panel (202) and at least one magnet (204) mounted to the protective panel (202). The magnet (204) is configured to be attracted to an internal wall (106) of a passenger compartment (104) of an elevator car (102) so as to retain the protective panel (202) against the internal wall (106). The magnet (204) may be retained against a support (210) of the protector (200) by a retainer assembly (220). The protector (200) may further comprise an electrical device which comprises a lighting device (240) configured to emit light into the passenger compartment (104) of the elevator car (102).

An elevator car (2) comprising a passenger compartment defining an interior space (4) surrounded by sidewalls (62, 63, 64) and at least one car door; and at least one lighting arrangement (11) configured to illuminate the interior space (4). Said lighting arrangement (11) is associated with a ventilation system (18) configured to ventilate the interior space (4) even in a situation where the car door is closed.

An illustrative example embodiment of an elevator cab ventilation device includes a fan module and a ventilation controller that is configured to control operation of the fan module based on an indication of a position of at least one door of the elevator cab. The controller is configured to control the fan module to operate in a first mode to move a first amount of air per unit time when the door is in a first open position. The controller is configured to control the fan module to operate in a second mode to move a second, larger amount of air per unit time when the door is in a second, different open position.

A protector (200) for an elevator car (102) includes a protective panel (202) and at least one magnet (204) mounted to the protective panel (202).
