When an instruction to request increase in the amount of air supply of air supply fan () is generated, operating conditions of air conditioner () is determined based on outdoor temperature information acquired by outdoor temperature acquisition unit () and indoor temperature information acquired by indoor temperature acquisition unit (). Then, air conditioner () is instructed on the determined operating conditions.

Air conditioning system and control unit

Control device () includes air conditioning controller () and air conditioning load factor calculator (). Air conditioning load factor calculator () calculates air conditioning load factorsand the like for rooms. Air conditioning controller () calculates a distribution of air volumes of air conveyed from an air conditioning room to the rooms based on air conditioning load factors (). Air conditioning controllercontrols air conveyance fans (to) in accordance with the distribution of the air volumes.

Air conditioning system, air-conditioning control program, and storage medium storing air-conditioning control program

Detector () detects information regarding air quality. First communicator () is compatible with a first system for controlling equipment. Second communicator () is compatible with a second system for accumulating the information regarding the air quality. Controller () transmits the information regarding the air quality to the second system based on a state of the information regarding the air quality having been detected.

Sensor device and air-conditioning management system

A ventilation and air conditioning system includes: an outdoor air supply fan; an exhaust fan; and a system controller to control operations of the outdoor air supply fan and the exhaust fan. The system controller includes: a link controller; an exhaust air volume receiver; a disconnection determinator; and a disconnected state supply air controller. The link controller controls the outdoor air supply fan and the exhaust fan in a linked manner. The exhaust air volume receiver receives, from the exhaust fan, an exhaust air volume signal indicating an exhaust air volume of the exhaust fan. The disconnection determinator determines a disconnected state where the exhaust air volume receiver fails to receive the exhaust air volume signal. The disconnected state supply air controller controls the outdoor air supply fan at a predetermined air volume when the disconnected determinator determines the disconnected state.

Ventilation air conditioning system and outdoor air supply fan

A ventilation control device () includes a total exhaust air volume reader (), an exhaust device specification reader (), an exhaust air volume distributor (), and an exhaust air volume instructor (). The total exhaust air volume reader () reads the total exhaust air volume set to a building. The exhaust device specification reader () reads a maximum exhaust air volume of each of exhaust devices () as a specification of the exhaust device (). The exhaust air volume distributor () sets the exhaust air volume of each exhaust device () by distributing the exhaust air volume read by the total exhaust air volume reader () according to the maximum exhaust air volume of the exhaust device () read by the exhaust device specification reader (). The exhaust air volume instructor () instructs, to each exhaust device (), the exhaust air volume set by the exhaust air volume distributor ().

Ventilation control device and ventilation system

A ceiling fan includes a connecting portion fixed to a ceiling, an electric motor having a rotation shaft disposed on a lower portion of the connecting portion, a temperature detector provided on a lower portion of the electric motor for detecting a peripheral temperature, and a controller for estimating a room temperature based on the temperature detected by the temperature detector and driving the electric motor according to the estimated room temperature.
