Abstract: A refrigeration device is provided having an air pressurizing device and a shroud enclosing the air pressurizing device and defining a first air flow path for an air flow generated by the air pressurizing device. The air pressurizing device and the shroud are positioned in a front side of the room air conditioner. A back side of the air conditioner includes air outlets communicating with an exterior of the air conditioner. A second air flow path extends between the first air flow path and the air outlets. A slider member is positioned in the second air flow path such that in a first position the second air flow path is closed to prevent communication between the first air flow path and the air outlets and in a second position of the slider member, the second air flow path is open to allow communication between the first air flow path and the air outlets.
