摘要： A centrifugal fan mounted in an air conditioner has the following relationship: outer diameter of a side plate of the centrifugal fan>outer diameter of the blade rear-edge part on side-plate side>diameter of the blade rear-edge part on main plate side>outer diameter of the main plate. In the centrifugal fan, the blade rear-edge part is positioned inside from a straight line connecting the connection point between the blade rear-edge part and the main plate, to the connection point between the blade rear-edge part and the side plate, as viewed from the rotation axis. The blade rear-edge part has a shape such that the distance from the rotation axis becomes larger from the main plate toward the side plate.

摘要： An air-conditioning system includes: an air-conditioning apparatus in which indoor units are connected to an outdoor unit; a conveying fan; and control means for controlling the air-conditioning apparatus and the conveying fan on the basis of a target evaporating temperature. The control means resets an upper limit of the target evaporating temperature when: a control determination temperature difference which is a difference between a set temperature and a temperature of an air-conditioned space is within a predetermined range; a humidity of the air-conditioned space is equal to or lower than a predetermined value; and a thermo-ON indoor unit and a thermo-OFF indoor unit are present together in the same air-conditioned space.
