  According to this configuration, the inclination angles of the first drain pan 20 and the second drain pan 30 can be adjusted according to, for example, the amount of drain water at the installation location or the inclination angle of the installation surface 80. For example, drainage of drain water from the first drain pan 20 and the second drain pan 30 can be promoted by making the tilt angle of the second drain pan 30 larger than the tilt angle of the first drain pan 20. Therefore, it is not necessary to arrange a large drain pan in the outdoor unit 1. Therefore, according to the present invention, it is possible to provide the outdoor unit 1 of the refrigeration cycle apparatus capable of saving space even when the outdoor unit 1 is installed in a humid area. Moreover, since the space-saving of the outdoor unit 1 can be achieved, the carrying work at the time of installation of the outdoor unit 1 becomes easy.

  Further, in the outdoor unit 1 of the refrigeration cycle apparatus of the first embodiment, a heater for preventing freezing can be disposed on either the first bottom plate 22 or the second bottom plate 32. According to this configuration, for example, the drain water can be prevented from freezing by installing the heater only on the drain pan with a small inclination without installing the heater on the drain pan with a large inclination angle. Therefore, according to this structure, the installation cost of a heater can be held down. Moreover, since the electric usage-amount in the outdoor unit 1 can be reduced, a running cost can be reduced and energy consumption can be reduced.
