Abstract

An air conditioning apparatus includes a centrifugal fan mounted in an interior of a casing and a pressure sensor. The pressure sensor can have a primary-side pressure detection tube opened in a position adjacent to a circumferential part of the casing on an inlet side surface of the bell mouth of the fan when the bell mouth is seen from a direction along the rotary shaft to detect a primary-side pressure of the centrifugal fan. Alternatively, the pressure sensor can have a primary-side pressure detection tube opened in a position adjacent to a circumferential part of the casing on a heat exchanger compartment side surface of the partition member when the partition member is seen from a direction along the rotary shaft to detect a primary-side pressure of the centrifugal fan.
