  • AIR-CONDITIONING UNIT
    Publication number: 20220097481
    Abstract: An air-conditioning includes a blower, a unit casing, an upstream partition, and a fan partition. The blower includes a centrifugal fan and a fan casing. The unit casing defines an upstream passage at a position upstream of the blower. The upstream partition is fixed to the unit casing to divide the upstream passage into a first upstream passage through which a first gas flows and a second upstream passage through which a second gas flows. The fan partition is fixed to the fan casing to divide an inner space of the fan into a first fan passage through which the first gas flows and a second fan passage through which the second gas flows. The unit casing defines an opening and includes a cover that closes the opening. The opening has an opening area such that the blower is removable from the unit casing through the opening.
