They are arranged in a line vertically so that they are higher than 41b. By arranging each of the service valves 41a and 41b in a line in the vertical direction, compared to the one arranged in a line in the horizontal direction (conventional),
The size of the parent unit 1 in the width direction can be reduced. The service valve (thick pipe) 41b of the gas pipe is arranged in the lower position in order to facilitate the connection of the gas pipe drawn out from the four-way valve 27. Since the connecting portion of the gas pipe of the four-way valve 27 is downward (not shown), it is difficult to draw the gas pipe drawn from the connecting portion of the four-way valve 27 in the parent unit 1 to the upper position, and thus the lower pipe. This is because if it is routed to, the connection will be easy.

In the air conditioner described above, the P / C compressor 19 is most preferentially operated for a long time as compared with the other compressors 15 and 17 in terms of operation control. Therefore, when compared with the other compressors 15 and 17, the P / C compressor 19 is usually used.
Is generally maintained frequently.

きる。Further, in the main body 10 of the parent unit 1, as shown in FIG. 2, the flow divider 45 connected to the heat exchangers 29 and 31 is arranged on the rear surface side of the main body. By arranging the flow divider 45 on the back surface side of the main body in this way, the opening space S on the front surface side of the main body can be made wider than in the case where the flow divider 45 is arranged on the front surface side of the main body. According to this embodiment, when the service panel 39 is opened, the degree of exposure of the compressor and the like is high, and therefore maintainability can be improved.

If the two heat exchangers are accommodated in the main body 10 of the parent unit 1 with the opening sides of 9, 31 facing each other, the remaining equipment such as the compressor that constitutes the refrigerant circuit is composed of two heat exchangers. Since it can be housed in the enclosed space, the parent unit 1 can be designed compactly. Further, since the service panel 39 is provided in the central portion of the main body 10, by opening the service panel 39, it is possible to perform maintenance of the devices that form the refrigerant circuit, and thus maintainability can be improved.
