次に、本実施形態に係る空気調和装置(1)の運転動作について説明する。この空気調和装置(1)では、各室内ユニット(30a,30b)で暖房を行う運転と、各室内ユニット(30a,30b)で冷房を行う運転とが可能となっている。
上記実施形態は、全ての室内熱交換器(33a,33b)の出口冷媒温度Tgc(1)及びTgc(2)の平均値Tgc(a)と、制御対象の室内熱交換器(33a,33b)の出口冷媒温度Tgc(1)及びTgc(2)との偏差ΔTgc(1)及びΔTgc(2)を算出し、この偏差ΔTgc(1)及びΔTgc(2)が、出口冷媒温度Tgc(1)及びTgc(2)の目標冷媒温度Tgc(S1)及びTgc(S2)と上記平均値Tgc(a)との偏差である目標値ΔTgc(S1)及びΔTgc(S2)に近づくようにした。したがって、上記実施形態によれば、高圧冷媒の圧力変動に伴って各室内熱交換器(33a,33b)の出口冷媒温度が変動Tgc(1)及びTgc(2)しても、上記偏差ΔTgc(1)及びΔTgc(2)の変動を抑制することができる。この結果、高圧冷媒の圧力変動が生じても、各室内膨張弁(34a,34b)の開度を調節する必要がなく、各室内熱交換器(33a,33b)の出口冷媒温度Tgc(1)及びTgc(2)を安定して制御することができる。よって、上記各室内熱交換器(33a,33b)の暖房能力を安定させることができる。
本発明は、上記実施形態について、以下のような構成としてもよい。
Claims (1)
- 圧縮機(22)、熱源側熱交換器(23)及び膨張機構(24)を有する熱源側回路(21)と、開度可変な制御弁(34a,34b)が接続された利用側熱交換器(33a,33b)を有し且つ互いに並列状態で上記熱源側回路(21)に接続された複数の利用側回路(31a,31b)とを備え、高圧冷媒の圧力が臨界圧力以上となる冷凍サイクルを行う冷媒回路(10)と、
上記利用側熱交換器(33a,33b)の放熱時に、上記各利用側熱交換器(33a,33b)の出口冷媒温度を所定温度に制御するコントローラ(50)とを備えた冷凍装置であって、
上記コントローラ(50)は、上記各利用側回路(31a,31b)における利用側熱交換器(33a,33b)の出口冷媒温度と、全ての利用側熱交換器(33a,33b)の出口冷媒温度の平均値との偏差が、所定の目標値になるように上記各利用側回路(31a,31b)の制御弁(34a,34b)の開度を調節する弁制御部(50a)を備え、
上記弁制御部(50a)の目標値は、上記各利用側熱交換器(33a,33b)が設けられる室内の目標空気温度に基づいた上記各利用側熱交換器((33a,33b)の出口冷媒温度の目標冷媒温度と上記平均値との偏差である
ことを特徴とする冷凍装置。
