A ventilation system includes a first ventilation device, a second ventilation device, a sensor, and an electronic controller. The first ventilation device includes a first fan. The second ventilation device includes a second fan. The sensor is attached to the first ventilation device. The sensor is configured to detect a state of air and to transmit a detection signal indicative of the detected state of air. The electronic controller is configured to receive the detection signal of the sensor and to control the first ventilation device and the second ventilation device based on the detection signal.

A method of releasing an output-suppressed control state in an air conditioning system that includes a control device configured to control one or more air conditioners, and a management device configured to be connected to the control device via a network to transmit, to the control device, a command to control output suppression of an air conditioner from among the one or more air conditioners to cause the air conditioner to be in the output-suppressed control state, includes a confirmation step of confirming whether communication between the control device and the management device is disconnected; and a transmission control step of, in a case where the communication between the control device and the management device is not disconnected, prohibiting transmission of a command to release the output-suppressed control state to the control device without intervention of the management device, and in a case where the communication between the control device and the management device is disconnected, allowing transmission of the command to release the output-suppressed control state to the control device without intervention of the management device.

An extended reanalysis ensemble service includes a loader services application program interface configured to receive data parameters for a set of automated multisource data provisioning operations, provide climate source data from one or more disparate climate data collections specified in the data parameters to conversion utilities for transforming the climate source data into flat, serialized block compressed sequence files, and load the sequence files to a distributed file system of the extended reanalysis ensemble service, and a reanalysis ensemble service application program interface configured to receive operational parameters for the set of automated multisource data provisioning operations, convert the operational parameters to one or more methods recognized by a service interface of the extended reanalysis ensemble service to be converted to analytical operations executed by the extended reanalysis ensemble service, and provide results of the one or more analytical operations executed by the extended reanalysis ensemble service to a client.

A communication circuit includes first and second communication nodes including first and second control chips, respectively, and first and second communication chips connected to the first and second control chips, respectively. The first and second communication chips are connected to each other through first and second signal lines, and are configured to transmit a differential signal. The first communication chip includes an output port to output a level signal obtained from the differential signal to the first control chip. The communication circuit further includes a voltage division assembly connected to the first and second signal lines, and configured to cause a voltage value of the first signal line to be higher than that of the second signal line when the first and second signal lines are in idle state. The first control chip includes a detection port connected to the output port to acquire the level signal.

In an air-conditioning system including an outside air processing device and an air-conditioning device, an operation of either one of the outside air processing device or the air-conditioning device is stopped if a temperature/humidity state that is at least either the temperature or humidity of air in a target space is within a predetermined range and if the load factor of at least one of the outside air processing device or the air-conditioning device is below a predetermined lower limit.
