利用側制御装置17は、ユーザーから運転の開始の指令を受け、空気調和装置100の運転を開始する。その後、利用側制御装置17は、(ステップS2)へ移行する。 (Step S1)
The usage-
利用側制御装置17は、室内送風機9を最大風速で運転する。その後、利用側制御装置17は、(ステップS3)へ移行する。 (Step S2)
The use
利用側制御装置17は、室外温度検知器18を介して実際の室外温度を検知すると共に、室内温度検知器14から実際の室内温度を検知する。その後、利用側制御装置17は、(ステップS4)へ移行する。 (Step S3)
The use
利用側制御装置17は、利用側制御装置17に予め記憶されている室外温度と室内温度との関係に基づいて定められている室内送風機9の最適風速のデータと、実際の室内温度及び実際の室外温度を照合する。そして、実際の室内温度と実際の室外温度とから室内送風機9の最適風速を計算する。なお、ここで言う最適風速とは冷房運転又は暖房運転において、各室内温度と室外温度において空気調和装置100のシステム効率が最大となる風速を示す。その後、利用側制御装置17は、(ステップS5)へ移行する。 (Step S4)
The use-
利用側制御装置17は、室内送風機9の実際の風速が最適風速の範囲内であるかを判断する。室内送風機9の実際の風速が最適風速の範囲内である場合は、利用側制御装置17は、(ステップS7)へ移行し、それ以外は(ステップS6)へ移行する。 (Step S5)
The use
利用側制御装置17は、室内送風機9の実際の風速が最適風速の範囲に収まるように室内送風機9の風速を制御する。その後、利用側制御装置17は、(ステップS3)へ移行する。 (Step S6)
The use
以上のことから、本実施の形態によれば、空気調和装置100は、圧縮機3、室内熱交換器7、絞り装置6、及び室外熱交換器5が冷媒配管を介して接続され、冷媒が循環する冷媒回路と、室内熱交換器7に空気を送風する室内送風機9と、室外温度と室内温度との関係に応じて室内送風機9の風速が定められている風速データを記憶する利用側制御装置17と、を備え、利用側制御装置17は、実際の室外温度と実際の室内温度とを風速データに照合し、照合された風速データに基づいて室内送風機9の風速を制御する。
このようにすることで、外気負荷の大小に応じて室内送風機9の風速を変化させ、効率的な運転が行える空気調和装置100を得ることができる。 [Effect of the embodiment]
