Description
図1は、本発明の実施の形態にかかる空気調和機の構成例を示す図である。実施の形態にかかる空気調和機100は、室内機1aおよび1bと、室外機2とを備える。図1では、空気調和機100が室内機を2台備える構成としているが1台以上であればよい。また、室内機1aの構成と室内機1bの構成が異なる場合の例を説明しているが、複数の室内機が全て同じ構成であってもよい。すなわち、複数の室内機1aと単一の室外機2とが空気調和機100を構成してもよいし、複数の室内機1bと単一の室外機2とが空気調和機100を構成してもよい。また、室外機2は、ブレーカ61を介して交流電源60に接続される。
まず、室外機2が低待機電力状態から復帰する場合の動作について、図5を参照しながら説明する。図5は、空気調和機100の室外機2が低待機電力状態から復帰する動作の一例を示すフローチャートである。
次に、室外機2が動作状態から低待機電力状態に移行する場合の動作について、図6を参照しながら説明する。図6は、空気調和機100の室外機2が動作状態から低待機電力状態に移行する動作の一例を示すフローチャートである。
