摘要： An air conditioning apparatus includes a casing having intake and blow-out ports, a partition member dividing an interior of the casing, a heat exchanger, a centrifugal fan, a heater and a fan heat shield. The centrifugal fan includes a bladed wheel mounted in the fan compartment such that a rotary shaft of the bladed wheel is oriented along an opening direction of the fan entrance and an opening direction of the blow-out port, and the bladed wheel being made of resin. The heater is mounted in a blow-out port opposed space opposed to the blow-out port within a fan downwind space located on a downwind side of the bladed wheel within the fan compartment. The fan heat shield member is mounted in the fan downwind space in order to cover a part of the bladed wheel that is opposed to the heater.

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.

摘要： An air conditioning apparatus includes a casing having intake and blow-out ports, a partition member dividing an interior of the casing, a heat exchanger, and a centrifugal fan. The partition member has a fan entrance bored in opposition to the blow-out port. The centrifugal fan includes a bladed wheel mounted in the fan compartment such that a rotary shaft of the bladed wheel is oriented along the fan entrance and the blow-out port. The rotary shaft is disposed adjacent to a bladed wheel nearby lateral part of multiple lateral parts of the casing that are disposed along the opening direction of the fan entrance and the opening direction of the blow-out port. The blow-out port is at least partially disposed in a position adjacent to a blow-out port nearby lateral part of the multiple lateral parts of the casing and being opposed to the bladed wheel nearby lateral part.

摘要： An air conditioning apparatus includes a casing having intake and blow-out ports, a partition member dividing an interior of the casing, a heat exchanger, a centrifugal fan, and a heater. The centrifugal fan includes a bladed wheel having a plurality of rearward blades and sucks air existing in the heat exchanger compartment into the fan compartment through the fan entrance. The bladed wheel is mounted in the fan compartment such that a rotary shaft of the bladed wheel is oriented along an opening direction of the fan entrance and an opening direction of the blow-out port. The heater is mounted in a blow-out port opposed space. The blow-out port opposed space is a region opposed to the blow-out port within a fan downwind space. The fan downwind space is a space located on a downwind side of the bladed wheel within the fan compartment.

摘要： An air conditioning apparatus includes a casing having intake and blow-out ports, a partition member dividing an interior of the casing, a heat exchanger and a centrifugal fan. The centrifugal fan includes a hub and a bladed wheel having a plurality of rearward blades and sucks air existing in the heat exchanger compartment into the fan compartment through the fan entrance. The bladed wheel is mounted in the fan compartment such that a rotary shaft of the bladed wheel is oriented along an opening direction of the fan entrance and an opening direction of the blow-out port. The hub connects blow-out port side ends of the plural rearward blades and is configured to be rotated about the rotary shaft. The hub has an outer diameter smaller than an outer diameter of the rearward blades.

摘要： An air conditioning apparatus includes a casing having intake and blow-out ports, a partition member dividing an interior of the casing and having a fan entrance, a heat exchanger, a first drain pan mounted in the heat exchanger to receive water produced by dew condensation in the heat exchanger, and a centrifugal fan. The centrifugal fan includes a bladed wheel mounted in the fan compartment such that a rotary shaft of the bladed wheel is oriented along the fan entrance. The first drain is disposed adjacent to a drain pan nearby lateral part of multiple lateral parts of the casing that are disposed along the opening direction of the fan entrance. The rotary shaft is disposed adjacent to a bladed wheel nearby lateral part of the multiple lateral parts of the casing and being opposed to the drain pan nearby lateral part.

摘要： An air conditioning apparatus includes a casing having intake and blow-out ports, a partition member dividing an interior of the casing, a heat exchanger, and a centrifugal fan. The blow-out port is at least partially disposed adjacent to a blow-out port nearby lateral part of the casing along an opening direction of a fan entrance and the blow-out port. A fan downwind space is located on a downwind side of a bladed wheel within a fan compartment, and has a blow-out port opposed space and a blow-out port non-opposed space. A first guide member directs air existing in the blow-out port non-opposed space toward the blow-out port opposed space, and is mounted in a boundary region located astride of regions located on forward and rearward sides in a rotary direction within the blow-out port non-opposed and blow-out port opposed spaces, respectively.
