PURPOSE:To markedly improve an air flow velocity distribution for a heat exchanger and contrive enhancement of the cooling capability of a main body by a construction wherein a first evaporator and a first condenser which have smaller widths are disposed on the side nearer to cross flow fans. CONSTITUTION:Each of an evaporator 6 and a condenser 13 is constituted of a finned tube type heat exchanger with a small fin width S, and is split into two in a row direction. First heat exchangers 6a, 13a on the downstream side are made to have widths greater than the widths of second heat exchangers 6b, 13b on the upstream side, and the downstream-side heat exchangers 6a, 13a are disposed on the side nearer to cross flow fans 5, 12 so that large spacings can be provided between curved parts 4a, 4g of a fan casing 4 and the upstream-side heat exchangers 6b, 13b. |
