AIR CONDITIONING APPARATUS

摘要

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.

主权项

1. An air conditioning apparatus, comprising:
a centrifugal fan mounted in an interior of a casing, the centrifugal fan including a bladed wheel having a hub, a shroud and a plurality of rearward blades, the hub being coupled to a rotary shaft of a fan motor, the shroud being opposed to the hub and having a fan opening bored in a center part thereof, the rearward blades being disposed between an outer peripheral part of the hub and an outer peripheral part of the shroud, and a bell mouth inserted at an outlet end thereof into the fan entrance; and a pressure sensor having 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 when the bell mouth is seen from a direction along the rotary shaft to detect a primary-side pressure of the centrifugal fan.
