PROBLEM TO BE SOLVED: To reduce the number of components by increasing or decreasing the number of heat exchangers of the same structures to meet a magnitude of a load at each exchanger type, thereby commonly using a control box. SOLUTION: In small type outdoor units 1, heat exchanging fans 4 are respectively mounted on front surface walls of heat exchanging units 3. Only one fan 4 is mounted on the front wall of the each one unit 3. One operating range of the units 1 is 5 HP, and the other range is 7.5 HP. In intermediate type outdoor units 5, their operating ranges are each 8 to 13 HP, an engine unit 6 is disposed at a lower side, a heat exchanging unit 7 is disposed at an upper side, and they are stacked to constitute a package. In these intermediate type units 5, two types of heat exchanging fans 8 are mounted on top surfaces of the respective units 7. In large type outdoor units 9, their operating ranges are each 16 to 20 HP, three heat exchanging fans 8 installed on top surfaces of the respective units 7 are aligned and installed in a lateral direction. |
