Abstract

　精度の良いモータ電流が得られる電流検出装置及びこれを備えた空気調和装置を提供する。更には、該電流検出装置を備えた補正定数算出システム及び補正定数算出方法を提供する。電流検出装置（９）は、電流平準化部（９３）と、ＧＮＤ配線（９４）と、電流検出部（９５）とを備える。電流平準化部（９３）は、第２ファンモータ（８１）を駆動するための第２モータドライバ（８２）に通電される駆動電流（Ｉｄ）を平準化する。ＧＮＤ配線（９４）には、第２ファンモータ（８１）に通電されたモータ電流（Ｉｍ）と電流平準化部（９３）により平準化された駆動電流（Ｉｄ）とが流れる。電流検出部（９５）は、ＧＮＤ配線（９４）上を流れるモータ電流（Ｉｍ）と平準化された駆動電流（Ｉｄ）との和を検出する。
