PURPOSE:To minimize the total pressure loss of a cross-flow fan in a condition that a heat exchanger is arranged at the suction side of the fan. CONSTITUTION:A heat exchanger 2 is arranged so that respective parts of respective surfaces 21, 22 at the inflow side and the outflow side of air in a heat exchanger 2 describe curved surfaces intersecting orthgonally to the flow directions of airstreams F generated in respective parts of the suction side by the rotation of a cross-flow fan 1. |
