A computer system provides intelligent context-based control of air flow. An identity of a user and a location of the user within an area that includes one or more vents associated with a climate control system are identified. User preferences are determined based on the identity of the user. Characteristics of air flow in the area are adjusted based on the user preferences the user and the location of the user, wherein the characteristics of the air flow comprise one or more from a group of: a direction, and a flow rate. Embodiments of the present invention further include a method and program product for providing intelligent context-based control of air flow in substantially the same manner described above.

According to one embodiment, a control device for an air conditioner which is communicably connected to first and second terminal devices to be used by first and second users is provided. The control device includes a processor. The processor configured to receive a first personal set temperature which is a temperature set by the first user by operating the first terminal device, receive a second personal set temperature which is a temperature set by the second user by operating the second terminal device, and determine a set value of the air conditioner based on the first personal set temperature and the second personal set temperature.

Apparatus, systems and methods for ascertaining the occupancy of a building are presented. The building is divided into one or more control zones which correspond to physical areas of the building associated with controllable modules, such as HVAC units, lighting, irrigation, or other environmental features such as fountains, music, video, and the like. Zone parameters define how zone devices shall react to the number of occupants located in the particular zone. A building control system detects individual mobile devices in and around the building, and determines the locations of each device by using trilateration and/or location services. The identified mobile devices act as proxies for building occupants. The locations of these devices are correlated with the locations of the zones in the building, and the building control system then adjusts the operating parameters of the zone based on the number of devices present in the zone.

An air cleaner includes: a housing including an inlet and an outlet for air; an air blower configured to blow air introduced through the inlet to the outlet; a panel configured to face the outlet and including holes; a driver configured to move the panel with respect to the housing; and a controller configured to control the driver to move the panel to open or close a channel between the outlet and the panel and adjust an air volume discharged through the holes of the panel. Thus, the air cleaner prevents a cold draft phenomenon.

A building management system includes a building efficiency improvement system and method configured to monitor and control subsystems and equipment for improved efficiency of operation. A user device is configured to display a user interface for monitoring and controlling one or more building equipment efficiency parameters and settings. The building efficiency management system further includes a controller configured to collect and analyze data from equipment, generate displays of the operational status and efficiency levels, generate sets of alternative equipment control algorithms based on efficiency objectives, and present users with a set of alternative equipment control algorithms displayed via graphic user interface elements on the user device. The user device further provides a means to select and implement an alternate equipment control algorithm. The controller is further configured to receive inputs from the user device commanding changes to equipment controls and process transactions associated with changes to equipment configuration.

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.

The present disclosure relates to a heating, ventilation, and air conditioning (HVAC) system including a sensor system configured to detect heat indications within a plurality of areas of a conditioned space, wherein the sensor system comprise a thermal light detector, and a controller configured to receive feedback from the sensor system and, based on the feedback, control airflow distribution, via an airflow distribution system, such that airflow management for each of the plurality of areas is individually correlated to a heat indication detected for the respective area.

A heating, ventilation, and air conditioning (HVAC) control device is configured to record a plurality of actual occupancy statuses, to determine a plurality of corresponding predicted occupancy statuses, and to compare the plurality of predicted occupancy statuses to the plurality of actual occupancy statuses. The device is further configured to identify conflicting occupancy statuses based on the comparison. A conflicting occupancy status indicates a difference between an actual occupancy status and a corresponding predicted occupancy status. The device is further configured to identify timestamps corresponding with the conflicting occupancy statuses, to identify historical occupancy statuses corresponding with the identified timestamps, and to update the conflicting occupancy statuses in the predicted occupancy schedule with the historical occupancy statuses.

A control system has an air conditioner that communicates with a file server via a network. The file server includes a lifestyle log in which information associating lifestyle information indicating a lifestyle with a control method of the air conditioner is accumulated. A first control-operation functional unit operates the air conditioner based on a first control request acquired from a first device. A second control-operation functional unit selects a control method from the lifestyle log based on a second control request acquired from a second device with higher functionality than the first device, and operates the air conditioner using the selected control method.
