COMPRESSOR SYSTEM, COMPRESSOR CONTROLLER, AND COMPRESSOR CONTROL METHOD

To suppress deterioration of power efficiency of the entire compressor system according to conditions such as clogging of a filter of each compressor, in operation of the compressor system comprising a plurality of compressors.SOLUTION: In a compressor system having a plurality of compressors and a compressor controller that controls the operation of the plurality of compressors, each of the compressors comprises a filter that filters air, a compressor body that compresses air, and detection means of detecting a physical quantity correlated with the pressure loss of the compressor body. The compressor controller preferentially operates a compressor having higher power efficiency according to the physical quantity detected by the detection means among the plurality of compressors, and restricts the operation of a compressor having lower power efficiency.SELECTED DRAWING: Figure 1 【課題】複数の圧縮機を含んで構成される圧縮機システムの運転において、各圧縮機のフィルタの目詰まり等の状況に応じて、圧縮機システム全体の電力効率の低下を抑制する。【解決手段】複数の圧縮機と、複数の圧縮機の運転を制御する圧縮機制御装置と、を有する圧縮機システムでは、圧縮機のそれぞれは、空気を濾過するフィルタと、空気を圧縮する圧縮機本体と、圧縮機本体の圧力損失と相関がある物理量を検出する検出手段と、を備える。圧縮機制御装置は、複数の圧縮機のうち、検出手段によって検出された物理量に応じた電力効率が、より高い圧縮機の運転を優先的に行い、より低い圧縮機の運転を制限する。【選択図】図１
