PROBLEM TO BE SOLVED: To realize low noises and a high wind volume while restraining increase in an outer shape dimension of a unit as low as possible. SOLUTION: A central evaporator 51 and both side evaporators 52, 53 positioned on both sides thereof are arranged in a U shape in a top view at a vertical upright posture. Each evaporator comprises pairs of upper and lower head tanks 51A, 51B, 52A, 52B, 53A, 53B extending in parallel, and a large number of heat exchanging tubes 51C, 52C, 53C communicated and connected with a head tank on upper and lower ends. Adjacent ends of the upper head tank are communicated and connected with each other at upper connecting parts 56A, 57A. Adjacent ends of the lower head tank are communicated and connected with each other at lower connecting parts 56B, 57. A coolant supply pipe 92 is connected with one of the upper connecting parts 56A, 57A and the lower connecting parts 56B, 57B, and a coolant exhaust pipe 91 is connected with the other, so as to simplify a piping structure.
