Particularly, the opening/closing unit is configured such that air is supplied into at least one of the function module and a duct unit or simultaneously into both the function module and the duct unit.

A zoning system for a heating, ventilation, and/or air conditioning (HVAC) system includes a temperature control device configured to monitor a temperature in a zone of a structure for conditioning by the HVAC system and configured to send a wireless control signal including data based on the temperature, and a damper actuator configured to be associated with the zone and configured to adjust a position of a damper to control an airflow into the zone, where the damper actuator is configured to receive the wireless control signal from the temperature control device and configured to adjust the position of the damper based on the data.

A hygiene management device for an entrance hall is designed to emit far-UV light from upper and lower sides toward a person by reflecting the far-UV light emitted from the upper side to the person's lower body by a reflector located at the lower side, and reflecting the far-UV light emitted from the lower side to the person's upper body by a reflector located at the upper side. Accordingly, a sterilization effect on the person is improved.

An environment control system is an environment control system that controls an environment of a target space. The environment control system includes: an obtainer that obtains biological information of a person present in the target space and environmental information of the target space; an estimator that estimates, based on the biological information and the environmental information obtained by the obtainer, a position of the person in the target space and a condition level indicating a level of comfort felt by the person in regard to the environment; a generator that generates, based on the position and the condition level of the person estimated by the estimator, a control signal that controls an operation of a device provided in the target space; and an outputter that outputs the control signal generated by the generator to the device.

A sensor system for determining occupancy in a space generally includes a transmitter radio device that transmits radio signals over a channel in the space; a receiver radio device that receives the transmitted radio signals that have traveled through the space; and at least one processor implementing an occupancy-centric algorithm that determines occupancy in the space based on the radio signals. The at least one processor determines channel state information based on the radio signals transmitted over the channel, determines occupancy in the space based on the channel state information, and outputs an occupancy signal based on the determined occupancy.

A smart artificial intelligence based mobile robot having an air purification, humidification, dehumidification, and ultraviolet cleaning-based system to remove pathogens is disclosed. The robot also acts as an emergency alert system for break-ins and human fall detection using AI algorithm. The mobile robot operates and navigates intelligently using real time data collected from the environment through various sensors and input devices. An object detection module may use inputs from the camera to recognize people, pets, and others by pre-trained machine learning data set. The mobile purification, humidity management and sanitizing robot includes a ball bearing for balance and a motor controller, which drives two motors and wheels. The central controller of the smart mobile robot system has memory and processor to handle navigation, communication, notifications, and air handling system through real time data collection.

The personal tracking fan is a fan that is adapted for use with a client. The personal tracking fan is a robot. The personal tracking fan tracks the location of the client. The personal tracking fan adjusts the direction of the air flow such that the air flow is always directed at the client. The personal tracking fan incorporates a fan module, a control circuit, and a personal data device. The control circuit mounts on the fan module. The personal data device establishes a wireless communication link with the control circuit. The fan module generates the air flow. The personal data device is carried by the client. The personal data device transmits the position of the client to the control circuit. The control circuit adjusts the altitude and the azimuth angles of the air flow that are necessary to direct the air flow towards the personal data device.

A heating, ventilation, and air conditioning (HVAC) system includes a network of wireless remote climate sensors to develop a complete heat map of an enclosed space. The remote climate sensor is configured to collect temperature and humidity data on a zone of the enclosed space. The HVAC system uses a network of these sensors to obtain data points across the enclosed space. The resulting heat map is used by the HVAC system to determine where to direct air in the enclosed space. By comparing the temperature and humidity at a specific remote climate sensor with the user's desired temperature and humidity, the HVAC system can decide whether to increase or decrease the air flow through a variable damper that is located near the remote climate sensor. By conducting this analysis throughout the enclosed space and making incremental adjustments to the air flow in hot and cold spots in the enclosed space, the disclosed HVAC system provides even comfort to the user along with reduced energy consumption.

A hygiene management device for an entrance hall and a control method of the same are proposed. The hygiene management device may be installed in the space of the entrance hall, and when the opening of an entrance door is detected, air is discharged toward the entrance door by tilting an air discharger toward the entrance door, and when the closing of the entrance door is detected, the air discharger is tilted to a preset initial position to stop the discharging of air. Accordingly, during the opening of the entrance door, the introduction of external air into the space of the entrance hall may be minimized.

An air circulation device includes a housing including an exhaust, a base including a filter intake and a bypass intake, and a damper system adjustable between a filter state and a bypass state. The damper system includes a bypass damper translatable via a bypass actuator, a filter damper translatable via a filter actuator, a filter mechanism disposed between the filter damper and the filter intake, a motor coupled to the bypass actuator and the filter actuator that allows the bypass damper and the filter damper to translate between an open position and a closed position, and a control mechanism can also have a sensor. The control mechanism is configured to adjust the damper system between the filter state and the bypass state, and the sensor determines an air quality rating of the air and compares the air quality rating of the air to a predetermined air quality threshold.
