Abstract: An apparatus for detecting a pipe length in an air conditioning system includes a detector to detect a signal traveled through a pipe and a first impedance coupler that couples to one end of the pipe, where the detector detects the signal traveled through the pipe at the first impedance coupler. A processor determines a pipe length based on the detected signal and a signal generator generates the signal to be sent through the pipe. A second impedance coupler couples to another end of the pipe, where the signal generator sends the signal to the pipe through the second impedance coupler.

Abstract: Disclosed are an air conditioner integrated management system and an operational method of the same according to the present invention. The present invention can promptly detect and repair the device, where an error really occurred, by determining the error as an upper unit's in the case that the error occurred at the whole devices belonging to a lower unit managed by the upper unit.

Abstract: An integrated management system for controlling multi-type air conditioners can use a remote integrated management system to securely and automatically back up setting information for a local controller provided in at least one air conditioner system, which is disposed in a room or office and is being operated, thereby allowing an improvement of stability of the integrated management system.

Abstract: A system for controlling multiple air conditioners. The system includes a demand control unit configured to calculate an estimated power amount to be used by the multiple air conditioners based on an amount of power consumed by the multiple air conditioners during a predetermined time period, and to forcibly control an operation rate of one or more air conditioners based on a priority level assigned to the one or more air conditioners.

Abstract: A building management system controls an operation of a system related to state information provided from multiple systems within the building management system among the multiple systems. Because the building management system is operated to control the multiple systems in an interworking manner, the operation efficiency of the building management system can be improved.
