A humidifying air purifier includes a door assembly supported and configured to be selectively drawn out of a front side of a cabinet and drawn into the front side of the cabinet to respectively open and close an inner portion of the cabinet. The door assembly includes an accommodation portion configured to support an air filter and a humidifying device which are both drawn out of and into the humidifying air purifier with the door assembly.

An air conditioner connection system includes an air conditioner having a first device connected via a power line in a communication-capable manner, and a second device capable of performing radio communication with the air conditioner. The air conditioner includes an authentication process control unit that controls the first device to perform an authentication process when a starting request of the authentication process for performing power carrier communication is received from the second device, the first device includes an authentication process unit that performs the authentication process under the control of the air conditioner, and the second device includes an authentication start process unit that transmits the starting request of the authentication process to the air conditioner.

An air conditioning apparatus including a storage unit that stores therein a setting table in which a schedule of an air conditioning operation for one week is set, and a control unit that executes operation control according to the schedule in the setting table, the air conditioning apparatus including a remote controller that sets operation information of a target time slot as a part of one week, and a temporary storage unit that temporarily stores therein the set operation information of the target time slot, wherein the control unit executes operation control based on the operation information of the target time slot stored in the temporary storage unit in priority to the schedule in the setting table.

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.

Improved systems for heating and cooling a space may include a heating and cooling unit for providing heating and cooling functions mounted inside a housing assembly and a display unit mounted to the housing assembly. A control unit may be coupled to the heating and cooling unit and the display unit. The control unit may be operative to cause an image or video associated with heat be displayed on the display unit when the heating and cooling unit is in the heating mode of operation and to cause an image or video associated with coolness be displayed on the display unit when the heating and cooling unit is in the cooling mode of operation. The control unit may be coupled to a server that enables remotes operation of the system via a client application. Other implementations also may be provided.

Disclosed are methods for measuring building health index using some mandatory and set of optionally configured parameters and utilizing building monitoring system having a connection to sensors in or pertaining to a building, and including central computing environment and one or more display devices showing the measurement. A building utilizing this method may be installed with one or more sensors, and which may be communicating to a locally installed communication device or a centrally installed computing environment that can collect the measurements over a period.

A controller device for a heating, ventilation, and air conditioning (HVAC) system may output, while in a first state, a first user interface for display at a display device, where the first user interface includes first information at a first output size. The controller device may determine, while in the first state and based at least in part on whether an elapsed time since a most recent indication of user input received at a user input device exceeds a timeout period, that no users are physically proximate to the controller device. The controller device may, in response: transition the controller device from the first state to a second state and output a second user interface at the display device, where the second user interface comprises second information at a second output size that is larger than the first output size.
