Abstract

PURPOSE: To eliminate the uncertainty due to non-attendance and perform stable control, by detecting each compressor going into a dangerous state under some cause and automatically reduce the rotational frequency of the compressor.
CONSTITUTION: A station suction pressure transmitter 20, a station discharge pressure transmitter 21, a station discharge rate transmitter 22, and a station discharge temperature transmitter 23 are provided. The outputs of these transmitters are supplied to a station suction pressure controller 24, a station discharge pressure controller 27, a station discharge rate controller 26 and a station discharge temperature controller 25 to perform proportional integrations. The outputs of these controllers are applied to a flow value gate 28, which selects the lowest of these outputs and enters it into a driver speed controller 29. Therefore, the rotational frequency of compressors 2a, 2b is determined by the lowest of the proportional integration outputs
