The fan case includes a unit connecting portion for connecting the heat exchange unit. The partition member partitions an inside of the fan case into an upstream side space and a downstream side space. The partition member has an opening for allowing the upstream side space and the downstream side space to communicate with each other. The centrifugal fan includes an impeller including a plurality of backward curved blades. The centrifugal fan is arranged such that the impeller is located in the downstream side space and sucks air in the upstream side space through the opening. The blowout port is located on an outer side in a radial direction of the impeller in the downstream side space.
