Abstract: The air blower capable of exercising constant airflow rate control and a static pressure evaluation apparatus connectable to the air blower are provided, in which the air blower provides information for improving a duct shape and a duct path by calculating a static pressure in a duct connected to the air blower from a value of a current flowing through a brushless DC motor built in the air blower, a rotation speed of the brushless DC motor, a target airflow rate, and data on relations among these values; displaying at least one of a static pressure value and an evaluation, stored beforehand in accordance with a static pressure level, of the calculated static pressure; and, during installation of a ventilation fan, evaluating a duct resistance from the static pressure in the duct connected to the ventilation fan.

Abstract: An embedded ventilation fan includes a housing, a decorative panel, an air supply blower, an air exhaust blower, and a heat exchange element. The heat exchange element is disposed at a position where an air supply passage and an air exhaust passage cross each other in the housing. The decorative panel includes a front surface, a rear surface, an air supply slit opening, an air exhaust slit opening, and a non-open zone. The rear surface includes a protruding wall protruding toward an inner side of the housing. The non-open zone is a zone having no opening. The air exhaust slit opening is partitioned from the non-open zone by the protruding wall on the rear surface. The heat exchange element is disposed directly above the non-open zone and is not disposed directly above the air supply slit opening and the air exhaust slit opening.
