    摘要： Disclosed herein are a local ventilation equipment and a blower therein. The local ventilation equipment includes: a main body having an intake port in a bottom and an interior area therein; and a blower installed in the interior area of the main body to generate air flow that sucks outside air into the main body through the intake port. The blower comprises an impeller that rotates on a shaft extending laterally and has therein a space to which air sucked through a side is introduced; a scroll housing that accommodates the impeller and has a suction hole formed on a side via which outside air is introduced into the space; and a driving unit that is installed in a space between the main body and the scroll hosing to supply power to rotate the impeller.

    摘要： A fan apparatus is disclosed having a first fan and a second fan, both of which are centrifugal fans. Impellers of the first fan and the second fan can be located adjacent one another and adapted to rotate in opposite directions. A first outlet opening (ot1) provided on a housing of the first fan can be located relative to a second outlet opening (ot2) provided on a housing of the second fan such that a flow pattern of the first fan overlaps at least partially with a flow pattern of the second fan when viewed from a direction of a rotation axis of an impeller of the first fan.

    摘要： A centrifugal multi-blade blower includes an impeller, and a casing that accommodates the impeller, and draws in air at least from an inlet port of the casing which opens on one end side of a rotation shaft and blows out the air radially outward of the rotation shaft. The impeller includes a main plate that is joined to the rotation shaft, vanes which are arranged around the axis of the rotation shaft and the other end sides of which in the rotation axis direction are connected to the main plate, and a side plate that connects together the vanes on their one end sides in the rotation axis direction. The vanes are characterized in that an inlet angle on a cross-sectional surface crossing each inner peripheral edge part of the vanes on a meridian plane of the impeller in a predetermined direction is evenly made in the entire region from the side plate-side through the main plate-side, and that outer peripheral edge parts of the vanes are configured to be away from the axis of the rotation shaft from the main plate-side toward the side plate-side.

    摘要： A blower assembly including a housing for a first scroll fan and a second scroll fan that are connected by a shaft to a motor that rotates the fans. The first and second scroll fans are coaxially mounted on the shaft. Fresh air ports and recirculated air ports are provided for the circulation of fresh air and recirculated air, respectively. The fresh air ports and recirculated air ports may be selectively opened and closed by doors to control the flow of air from the outside and from the passenger compartment as controlled by the HVAC system.
