Claims (1)
- 永久磁石同期形の電動機を内蔵する圧縮機または当該電動機が連結される圧縮機の起動時に、停止事由が生じた場合、当該電動機への電圧印加を停止または再起動する条件判断部を有する電動圧縮機の制御装置において、
圧縮機の高圧側圧力を取得する高圧側圧力取得手段を有し、
前記条件判断部は、前記高圧側圧力取得手段から得られる高圧側圧力値と当該高圧側圧力値に基づいて導出される圧縮機の低圧側圧力値を基準に前記電動機への電圧印加を停止または再起動する工程を有し、
前記条件判断部は、予め試験によって求めておいた関数又はテーブルを用いて、低圧側圧力値を、前記高圧側圧力が当該低圧側圧力と平衡状態になっていると仮定して導出すること
を特徴とする電動圧縮機の制御装置。
