An air-conditioning device includes a plurality of duct modules and a power module. The duct modules each have a temperature-adjusting unit, an air flow-guiding unit and an energy transmission module. The temperature-adjusting unit is disposed at the second end of the duct module, and has opposing first and second side surfaces. The air flow-guiding unit is disposed at the duct module. The energy transmission module is disposed between the temperature-adjusting unit and the air flow-guiding unit. The power module provides operational power for the duct modules. The air flow-guiding unit guides air flow to enter from the first end of the duct modules. The energy transmission strength of the air flow is enhanced from the energy transmission module. The air flow passes through the first or second side surface of the temperature-adjusting unit, and exists from the second end of the duct modules.

A thermostat my include a stored setpoint schedule, temperature sensors providing temperature sensor measurements; and a processing system configured to control an HVAC system based at least in part on the setpoint temperature and the temperature sensor measurements. The processing system may be configured to control the HVAC system by receiving an indication of a first time interval, where energy is available to the HVAC system at a first rate during the first time interval, energy is available to the HVAC system at a second rate during a second time interval that is outside of the first time interval, and the first rate is higher than the second rate; identifying a first one or more setpoints in the plurality of setpoints of the stored setpoint schedule that occur in the first time interval; and decreasing a temperature component of at least one of the first one or more setpoints.

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.

Devices, systems, and methods for building system commissioning automation are described herein. One device includes a controller of a plurality of building system devices having logic to receive a set of commands specified by a sequence of operations (SOO) script, execute the set of commands to run an SOO check on the plurality of building system devices, and generate a report including results of the SOO check.

Disclosed is an HVAC (heating, ventilation and air-conditioning) system which comprises a fluid flow duct (1), a fluid flow valve (7) which is arranged therein and has a valve body (5) in the fluid flow duct (1) and a valve motor (15) which moves the valve body (5), a control circuit for activating the valve motor, a sensor (8) in the fluid flow duct (1) and an evaluation module for evaluating signals of the sensor. To produce an automated functional control, the following procedure is adopted: a first actuation signal is preset for the valve motor by the control circuit, and the actuation signal corresponds to a first setpoint position of the valve body (5), registration of a first signal of the sensor (8) by the evaluation module, and determination of a functional diagnosis of the fluid flow valve on the basis of the first signal of the sensor.

There is provided an information processing apparatus including a control section which performs control of selecting, based on a state of a user, an ecological action capable of being carried out by the user from among a plurality of ecological actions, and of presenting the selected ecological action to the user.

In a central air-conditioning system, regional flow balancing valves for controlling flow of water return branch pipes are arranged on the water return branch pipes, and energy balancing valves are arranged on water return pipes of tail-end fan coils respectively. A control method includes: detecting flow in the water return branch pipes, and adjusting the flow in the return branch pipes to be smaller than or equal to a branch pipe set flow value; and detecting the temperature of return water in the water return pipes of the tail-end fan coils, controlling the temperature of the return water in the water return pipes of the tail-end fan coils to be greater than or equal to a tail-end return water set temperature value, detecting the room temperature and adjusting the opening degree of the energy balancing valves in temperature controllers.

Disclosed is an air conditioner. The air conditioner includes an outdoor unit. The air conditioner further includes an indoor unit located in a building and configured to distribute cool air to a space within the building. The air conditioner further includes an antenna unit configured to sense (i) movement of human bodies within the space or (ii) presence of human bodies located in the space and determine a number of human bodies based on the sensed presence, where the antenna unit includes a housing and a plurality of antenna arrays located on an outer surface of the housing.

A ventilation device for ventilating rooms, has a first air routing device for routing a first flow of air, the routing device having a first room-side outlet, a first flow space in which at least one first fan capable of bidirectional operation is arranged, and a first outside outlet; a second air routing device for routing a second flow of air, which is fluidically completely separate from the first air routing device and has a second room-side outlet, a second flow space in which at least one second fan capable of bidirectional operation is arranged, and a second outside outlet; an integral gas-solid heat exchanger adapted to route the first flow of air and the second flow of air in a respective set of passageways, in a fluidically separated but thermally coupled manner, wherein the solid in the first and the second air routing device additionally forms a respective regenerator.
