Description
図1は、本実施の形態に係る室外機100が収容する冷凍サイクル装置を示す図である。図1に示すように、室外機100は、圧縮機1、空気熱交換器2、膨張弁4、及び、蒸発器5が冷媒配管7により接続されて構成された冷凍サイクル装置が、例えば、角柱形状の筐体8に収容されたものである。空気熱交換器2は、ファン3とともに筐体8の上部に配置されている。室外機100は、トップフロー形式の形態のものであり、例えば、建物の屋上などに設置される。
図5(a)は、変形例に係る空気熱交換器30の概略図であり、図5(b)は、図5(a)の空気熱交換器30の直線部30aを矢印で示す方向から見た拡大側面図である。また、図6(a)は、変形例に係る空気熱交換器30の概略図であり、図6(b)は、図6(a)の空気熱交換器30の屈曲部30bを矢印で示す方向から見た拡大側面図である。図5、及び、図6に示すように、この変形例において、空気熱交換器30は、3列配置された第1熱交換器31と、その内側に配置された第2熱交換器35とにより構成されている。そのうち、第1熱交換器31の直線部30aには、粗面フィン22が設けられている。また、第2熱交換器35においては、屈曲部30bに平滑フィン27が設けられ、直線部30aに粗面フィン22が設けられている。
性能評価においては、IPLVと略称されるIntegrated Part Load Valueにおいて規定された指標に基づき評価を行った。IPLVは、指標として異なる4点の負荷における冷凍機の成績係数を定義し、それぞれの負荷での稼働割合に基づいて機器のエネルギー効率を評価するものである。評価対象として、従来例の空気熱交換器には、第1熱交換器20が4列配列され、屈曲されたものを採用した。また、本実施の形態に係る空気熱交換器2には、第1熱交換器20が3列と、第2熱交換器25が1列とが配列され、第2熱交換器25側に屈曲されたものを採用した。
