Alternatively, as shown in Fig. 10, the rear part of the partition plate (end) may be extended in the left-right direction to form a machine room long in the left-right direction, and the compression equipment may be placed in this machine room with the compression equipment facing left-right good. In this case, the depth of the main body can be made smaller than the width, which is especially advantageous when installed under eaves with a small depth.

Furthermore, in the embodiments shown in FIGS. 7 to 1a, the heat exchanger (3
od), (3oe) transmission m (50a) was made to face the side and top surfaces of the outdoor unit main body (a), but if it is configured so that it faces the side and bottom surfaces, the top surface can be brought into close contact with the eaves, Even more space can be saved.

〔Effect of the invention〕

As explained above, according to the present invention, the partition plate has the compressor installed approximately in the middle of the outdoor unit main body and closes the space between the blowers, so that the center of gravity of the outdoor unit main body is balanced. This improvement has the effect of making it easier to install, reducing the occurrence of vibrations, and preventing interference between blowers.

In addition, a partition plate is installed inside the compressor surrounded by a heat exchanger and a blower arranged on three or more walls of the main body, and the space between the blowers is closed, so the wall surface is not blocked by the compressor and the heat exchanger can be It has the effect of being able to be widely disposed and preventing interference between the blowers.

In addition, a heat exchanger is disposed on at least one of both sides and the upper and lower surfaces of the main body, and a partition plate is installed inside the compressor approximately in the middle of the main body, and the air blower is closed off. I decided to let them do it.

Since no heat exchanger is disposed on the back of the outdoor unit main body, the back surface can be installed closely to the wall surface, which has the effect of improving installation ease and preventing interference between blowers.
