Description
テーパ面３１ｂは第２の遠心送風機５の吸込面とファンケーシング５４の送風機吐出口５４ｂが形成される面の反対側の面の交点から始まり、第１の整流部３１の交点Ａは、回転軸４２の延長線よりも本体気流の上流側（第１の遠心送風機４、第２の遠心送風機５の空気の吐出方向の反対側）となる位置に設けられることが好ましく、まず、この交点Ａが回転軸４２から第１の遠心送風機４の本体気流の送風機吸込口４４ａの曲線開始端の間に位置する場合、第２の遠心式ファン５３の回転軸５２および第２の遠心送風機５からの空気の吐出方向と垂直な方向から見た場合に、第１の整流部３１の交点Ａは、第２の遠心式ファン５３の回転軸５２に沿った方向での第１の壁１ａとの距離Ｌ２が、第２の遠心送風機５の必要風量に応じた距離となる位置に設けられる。この交点Ａの位置を、「第２の遠心送風機５の必要風量に基づいて定めた交点Ａの位置」とする。これにより、第１の壁１ａと第１の整流部３１によって形成される流路が狭くなりすぎて、送風機吸込口５４ａに向けた空気の流れが阻害されてしまうことを抑制できる。 The taper surface 31b starts from the intersection of the suction surface of the second centrifugal blower 5 and the surface of the fan casing 54 opposite to the surface where the blower discharge port 54b is formed, and the intersection A of the first rectifying unit 31 is the rotation axis. It is preferable to be provided at a position that is upstream of the main body airflow from the extension line 42 (the opposite side of the air discharge direction of the first centrifugal blower 4 and the second centrifugal blower 5). when located between the rotation axis 42 of the curve start end of the first feed of the main body air flow of the centrifugal fan 4 air blower inlet 44a, from the axis of rotation 52 and the second centrifugal fan 5 of the second centrifugal fan 53 When viewed from a direction perpendicular to the air discharge direction, the intersection A of the first rectifying unit 31 is a distance from the first wall 1 a in the direction along the rotation axis 52 of the second centrifugal fan 53. L2 is a distance according to the required air volume of the second centrifugal blower 5 and It is provided in that position. The position of the intersection A is defined as “the position of the intersection A determined based on the necessary air volume of the second centrifugal blower 5”. Thereby, it can suppress that the flow path formed by the 1st wall 1a and the 1st rectification | straightening part 31 becomes narrow too much, and the flow of the air toward the air blower inlet 54a will be inhibited.
また、第１の整流部３１の交点Ａは、第１の遠心式ファン４３の回転軸４２に沿った方向での第１の遠心送風機４の第１の壁１ａ側の送風機吸込口４４ａとの距離Ｌ１が、第１の遠心送風機４の必要風量に応じた距離となる位置に設けられてもよい。この交点Ａの位置を、「第１の遠心送風機４の必要風量に基づいて定めた交点Ａの位置」とする。次に、第１の整流部３１の交点Ａが第１の遠心送風機４の本体気流の送風機吸込口４４ａの曲線開始端よりも本体気流の上流側に位置する場合（図８を参照）、第１の遠心送風機４の本体気流の送風機吸込口４４ａの曲線開始端と第１の遠心送風機４の本体気流の送風機吸込口４４ａの曲線開始端を通り回転軸４２方向のテーパ面３１ｃの距離Ｌ６が第１の遠心送風機の必要風量に応じた幅以上になるように第１の整流部３１の交点Ａを設定する。これにより、第１の整流部３１が送風機吸込口４４ａと対向する領域を覆いすぎて、送風機吸込口４４ａに向けた空気の流れが阻害されてしまうことを抑制できる。 Further, the intersection A of the first rectifying unit 31 is in contact with the blower suction port 44a on the first wall 1a side of the first centrifugal blower 4 in the direction along the rotation axis 42 of the first centrifugal fan 43. The distance L <b> 1 may be provided at a position that is a distance corresponding to the required air volume of the first centrifugal blower 4. The position of the intersection A is defined as “the position of the intersection A determined based on the required air volume of the first centrifugal blower 4”. Then, if the intersection point A of the first rectifying portion 31 is located upstream of the main air flow than the curve start end of the first centrifugal fan 4 body airflow feed air blower inlet 44a (see Figure 8), the first feed body airflow of the centrifugal fan 4 air blower inlet 44a of the curve start end of the first centrifugal blower 4 of the main body air flow feed air blower inlet 44a of the curve starting end of the street rotation axis 42 direction tapered surface 31c The intersection A of the first rectifying unit 31 is set so that the distance L6 is equal to or larger than the width corresponding to the required air volume of the first centrifugal blower. Thereby, it can suppress that the 1st rectification | straightening part 31 covers the area | region which opposes the air blower inlet 44a too much, and the flow of the air toward the air blower inlet 44a will be inhibited.
テーパ面３２ｂは第３の遠心送風機６の吸込面とファンケーシング６４の送風機吐出口６４ｂが形成される面の反対側の面の交点から始まり、第２の整流部３２の交点Ｃは、回転軸５２の延長線よりも本体気流の上流側となる位置に設けられることが好ましく、まず、この交点Ａが回転軸５２から第２の遠心送風機５の本体気流の送風機吸込口５４ａの曲線開始端の間に位置する場合、第３の遠心式ファン６３の回転軸６２および第３の遠心送風機６からの空気の吐出方向と垂直な方向から見た場合に、第２の整流部３２の交点Ｃは、第３の遠心式ファン６３の回転軸６２に沿った方向での第１の壁１ａとの距離Ｌ４が、第３の遠心送風機６の必要風量に応じた距離となる位置に設けられる。この交点Ｃの位置を、「第３の遠心送風機６の必要風量に基づいて定めた交点Ｃの位置」とする。これにより、第１の壁１ａと第２の整流部３２によって形成される流路が狭くなりすぎて、送風機吸込口６４ａに向けた空気の流れが阻害されてしまうことを抑制できる。 The taper surface 32b starts from the intersection of the suction surface of the third centrifugal blower 6 and the surface of the fan casing 64 opposite to the surface where the blower discharge port 64b is formed, and the intersection C of the second rectifying unit 32 is the rotation axis. preferably provided in a position on the upstream side of the main body air flow than 52 extension of, first, the curve starting edge of the intersection point a from the rotational axis 52 the second feed body airflow of the centrifugal blower 5 air blower inlet 54a Is located between the rotary shaft 62 of the third centrifugal fan 63 and the direction C perpendicular to the discharge direction of the air from the third centrifugal blower 6, the intersection C of the second rectifying unit 32. Is provided at a position where the distance L4 to the first wall 1a in the direction along the rotation axis 62 of the third centrifugal fan 63 is a distance corresponding to the required air volume of the third centrifugal fan 6. The position of the intersection C is defined as “the position of the intersection C determined based on the required air volume of the third centrifugal blower 6”. Thereby, it can suppress that the flow path formed by the 1st wall 1a and the 2nd rectification | straightening part 32 becomes narrow too much, and the flow of the air toward the air blower inlet 64a will be inhibited.
また、第２の整流部３２の交点Ｃは、第２の遠心式ファン５３の回転軸５２に沿った方向での第２の遠心送風機５の第１の壁１ａ側の送風機吸込口５４ａとの距離Ｌ３が、第２の遠心送風機５の必要風量に応じた距離となる位置に設けられてもよい。この交点Ｃの位置を、「第２の遠心送風機５の必要風量に基づいて定めた交点Ｃの位置」とする。次に、第２の整流部３２の交点Ｃが第２の遠心送風機５の本体気流の送風機吸込口５４ａの曲線開始端よりも本体気流の上流側に位置する場合（図９を参照）、第２の遠心送風機５の本体気流の送風機吸込口５４ａの曲線開始端と第２の遠心送風機５の本体気流の送風機吸込口５４ａの曲線開始端を通り回転軸５２方向のテーパ面３２ｃの距離Ｌ７が第２の遠心送風機５の必要風量に応じた幅以上になるように第２の整流部３２の交点Ｃを設定する。これにより、第２の整流部３２が送風機吸込口５４ａと対向する領域を覆いすぎて、送風機吸込口５４ａに向けた空気の流れが阻害されてしまうことを抑制できる。 Further, the intersection C of the second rectifying unit 32 is in contact with the blower suction port 54a on the first wall 1a side of the second centrifugal blower 5 in the direction along the rotation axis 52 of the second centrifugal fan 53. The distance L3 may be provided at a position where the distance is in accordance with the required air volume of the second centrifugal blower 5. The position of the intersection C is defined as “the position of the intersection C determined based on the necessary air volume of the second centrifugal blower 5”. Then, if the intersection point C of the second rectifying unit 32 is located upstream of the main air flow than the curve starting end of the second centrifugal fan 5 body airflow feed air blower inlet 54a (see Figure 9), the second feed body airflow of the centrifugal blower 5 air blower inlet 54a of the curve start end and a second centrifugal fan 5 of the main body air flow feed air blower inlet 54a of the curve starting end of the rotary shaft 52 direction as the tapered surface 32c The intersection C of the second rectifying unit 32 is set so that the distance L7 is equal to or larger than the width corresponding to the required air volume of the second centrifugal blower 5.
