  • the noise value and the number of revolutions can be reduced by providing a rib.
  • the reason is that in a case where the rib is absent and a resistive element to the flow such as a heat exchanger or the like is present, the higher the draft resistance of the resistive element becomes, the more the reverse flow phenomenon, in which the airflow is headed toward the inner part of the fan from the blowing-out opening 18, occurs at the blowing-out opening 18 of the sirocco fan 1 as illustrated in Fig. 9 , and this becomes a cause of increasing the noise value and the number of revolutions. That is, as illustrated in Fig.
  • an airflow blown out from gaps between the blades on a main plate side is headed toward both ends of the scroll along the scroll, and in the vicinity of both ends of the tongue portion 8, flows into a gap between the tongue portion 8 and the fan body 11, without flowing toward the blowing-out opening 18.
  • the airflow further flows into the gaps between the blades, and is blown out from the gaps between the blades on the main plate side, so that a flow 22 blown out toward the outer part of the scroll is caused.
  • the static pressure fluctuation on the wall surface is increased in the vicinity of both ends of the tongue portion, and a flow passing through the gaps between the blades many times is caused, and an air-blowing amount of the airflow that circulates in the inner part of the fan increases. Thereby, the air-blowing amount of the airflow passing through the gaps between the blades is also increased. This results in increasing the static pressure fluctuation on the blade surface, and increasing the noise value.
  • the airflow blown out from the gaps between the blades on the main plate side is headed toward both ends of the scroll along the scroll.
  • An air-flowing amount flowing into the gap between the tongue portion 8 and the fan body 11 in the vicinity of both ends of the tongue portion 8, without flowing toward the blowing-out opening 18 can be reduced.
  • the noise value and the number of revolutions can be reduced as shown in Table 5.
