  In order to reduce the weight of the outdoor unit 300, an aluminum heat exchanger (for example, a so-called microchannel heat exchanger) may be employed. This type of heat exchanger does not include a tube plate 311 that supports the end of the heat exchanger.

In the case of such an outdoor unit including a heat exchanger not provided with the tube plate 311, the following problems occur when the outdoor units are stacked.
When the outdoor units are stacked, the load of the outdoor unit placed on the outdoor unit is applied to the lower outdoor unit. When the load is applied to the entire top panel, the casing of the outdoor unit is hardly deformed, but when the load is applied to one of the top panels, the casing may be deformed. For example, when a load is applied to a structurally weak portion, the casing is likely to be deformed. In particular, the rear edge portion 405a of the rear plate 405 on the machine room MR side is structurally weak. Therefore, in the outdoor unit 300 having a conventional structure, the tube plate 311 is disposed in the vicinity of the rear edge portion 405a of the rear plate 405, and the top plate is supported by the tube plate 311. This prevents an excessive load from being applied to the rear edge 405a of the rear plate 405. However, an outdoor unit that employs a heat exchanger without the tube sheet 311 cannot adopt such a structure due to the absence of the tube sheet 311. For this reason, the possibility of the casing being deformed is higher than that of the outdoor unit 300 having a conventional structure (the outdoor unit 300 having a structure in which the top plate is supported by the tube plate).

  This invention is made | formed in view of such a situation, The objective is to provide the packaging member for air conditioners which can suppress a deformation | transformation of a casing.

The invention according to claim 1 includes a casing that encloses a fan chamber in which a heat exchanger and a blower device are arranged, and a machine room in which a compressor is arranged, and the heat exchanger has side surfaces facing each other.

FIG. 9A shows a state in which an excessive load is applied to the machine room MR side portion of the top plate 211 in the outdoor unit 100 packed with the upper packing member 500 having a conventional structure.
The upper packing member 500 having a conventional structure contacts the top plate 211 over the entire portion corresponding to the rear plate 261. For this reason, when a load is applied to the upper packing member 500, the second cushioning material 510 is deformed, whereby the top plate 211 is bent downward as indicated by an arrow B. As a result, an excessive load is applied to the rear edge portion 267 of the rear surface plate 261, and the rear edge portion 267 of the rear surface plate 261 cannot withstand the load and deforms.

Therefore, as shown in FIG. 9B, a non-contact portion 27 b is formed in the upper packing member 10 so that a load is not applied to the rear edge portion 267 of the rear plate 261.
In the case of such a configuration, even if the second cushioning material 22 is deformed due to an excessive load applied to the machine room MR side portion of the top plate 211, the second cushioning material 22 is located at the rear center portion NE. Since no contact is made, no load is applied to the rear center portion NE of the top surface, and consequently no load is applied to the rear edge portion 267 of the rear plate 261. Thereby, the deformation of the third outer plate 260 is suppressed.
