A network of wireless remote climate sensors in a heating, ventilation, and air conditioning (HVAC) system permits the creation of personalized microclimates within an enclosed space. In addition to collecting temperature and humidity data, the wireless remote climate sensors can detect whether the enclosed space is occupied by a human. Human detection is made possible by optional cameras, microphones, and gas sensors on the wireless remote climate sensors. As the human moves throughout the enclosed space, the HVAC system is able to track the human's movement using the wireless remote climate sensors. The HVAC system may adjust airflow to different portions of the enclosed space based on the human's location. The result is an efficient use of system resources to keep users at their ideal temperature.

A heating, ventilation, and air conditioning (HVAC) system may be zoned into one or more zone. The HVAC system may include HVAC components, sensors, and one or more register vents that may include vent dampers (e.g., electronically controllable vent dampers or manually operated vent dampers). Opening and closing of the vent dampers may facilitate creating zones or sub-zones in the HVAC system configuration. An HVAC control system may receive a request for conditioned air in one or more of the zones, determine a damper setting for at least one of the vent dampers, communicate the determined damper setting to a vent damper or user interface, determine which HVAC components should be active, if any, and/or provide controls signals to activate or keep active the HVAC components that are determined to be active.

A HEPA/VOC air handling system having a HEPA air filtration unit, an air handling unit, a fresh air sensor system, a return air sensor system, an air handling air sensor, and a controller.

Provided is a fan control apparatus which includes: a first sensor; a second sensor; an RF fan; and a controller. The first sensor is provided in a first room, and is configured to acquire a measured value of at least one condition selected from conditions of atmospheric pressure, temperature, and humidity for the first room, the second sensor is provided in a second room adjacent to the first room, and is configured to acquire a measured value of the same condition as the at least one selected condition for the second room, the RF fan is placed at a boundary between the first and second rooms, and the controller is configured to control a rotational speed and rotational direction of the RF fan in such a manner that the measured values of the first and second sensors are the same.

A ventilation fan includes a body unit, which has a fan disposed in a body case and a fan controller operable to control an air volume of the fan. The ventilation fan also includes a sensor module having an indoor environment detecting sensor and a module controller operable to control a detecting operation of the indoor environment detecting sensor. The body unit has a module mount on which the sensor module is mounted and another sensor module can be mounted in place of the sensor module. The module mount is connected to the fan controller. The module controller outputs detection information obtained based on a detection result of the indoor environment detecting sensor to the fan controller, which in turn controls the air volume of the fan based on the detection information inputted thereto.

Provided is an artificial intelligence air conditioner for calibrating sensor data. The artificial intelligence air conditioner includes a sensor unit configured to acquire sensor data; a communication unit configured to receive at least one of external sensor data or environment information from at least one of an external air conditioner or an internet of things (IoT) device; and a processor. The processor is configured to generate estimated sensor data corresponding to the sensor unit using a sensor data estimation model, the received external sensor data and the received environment information, determine whether the acquired sensor data is abnormal using the generated estimated sensor data, perform an air conditioning function using the acquired sensor data if the acquired sensor data is determined as normal, and perform the air conditioning function using the generated estimated sensor data if the acquired sensor data is determined as abnormal.

A system for controlling thermal comfort in a space is provided with variable mode of operation. This system may include a conditioner for conditioning air in the space, and a sensor for measuring a temperature in the space. A controller is provided for controlling the conditioner based on the temperature sensed by the sensor, and a fan for circulating air within the space is regulated based on the temperature sensed by the sensor. A related system for controlling a fan based on height is also provided, as is a system and method for easily and efficiently determining the height of a fan using a simple camera, such as one on a “smart” phone. A further aspect pertains to a controller, such as for example a portable handheld device, having a user interface adapted for suggesting an increase in a set point temperature of a thermostat based on the selected speed of the fan.
