PURPOSE:To improve operability of mounting a heat exchanger on a body and to delete the number of components by forming an engaging groove for engaging a U-shaped pipe disposed on a side face of the exchanger on a casing. CONSTITUTION:A tongue 20 partitions suction and discharge sides of a first fan casing 18 and has an engaging groove 24 which is integrally formed and in which a U-shaped pipe 22 at one end of a cooler 21 of an indoor heat exchanger is inserted and positioned. A U-shaped pipe 26 at the other end of the cooler 21 is screwed down at a boss 15 integrally formed at the casing 18. Thus, since the cooler 21 is inserted at the pipe 22 of the one side to be engaged with the groove 24 formed on the tongue 20 of the casing 18 and screwed down at the pipe 26 of the other side the boss 25 of the casing 18, a screw-down operation can be reduced to a minimum limit. |
