This air conditioner has a plurality of indoor units requiring different amounts of time for a freezing step. In order to execute a cleaning operation for cleaning the surface of each indoor heat exchanger, a control device has a function of controlling a freezing cycle through a compressor, an outdoor heat exchanger, an expansion valve, and the indoor heat exchanger in sequence. The control device executes, as the cleaning operation, freezing of the indoor heat exchanger, defrosting of the indoor heat exchanger, and drying of the indoor heat exchanger in this order. During the freezing of indoor heat exchangers, the freezing step is executed on the indoor units in descending order of the amount of time required therefor. For an indoor unit which requires the shortest amount of time for the freezing step, start of the freezing step is delayed such that the freezing step ends simultaneously with the freezing step for an indoor unit which requires a longer amount of time.

Provided is a novel rotary compressor having increased strength of an upper end plate and thus achieving increased mechanical reliability. An upper end plate 22A has an outer shape formed by: a first arc forming a plurality of fixed regions 32A to 32C welded to a tubular body 14, the first arc being concentric with the center C of the tubular body 14 and having a radius substantially the same as the radius of an inner wall of the tubular body 14; and a sectoral second arc forming connecting sides 33A to 33C connecting fixed region end portions 35A to 35C of adjacent fixed regions 34A to 34C, the second arc being formed by connecting to the center C of the tubular body 14. The radius of the second arc is greater than the radius of the first arc, and the second arc is an arc protruding toward the inner wall of the tubular body 14 and forming a passing hole 37A with respect to the inner wall of the tubular body 14. Because the connecting sides forming the outer peripheral edge of a compression mechanism holding unit are arc-shaped, formation of a shape-varying portion having a stress concentration is prevented. Accordingly, the strength of the upper end plate is increased and higher mechanical reliability is achieved. Further, because the connecting sides forming the outer peripheral edge of the compression mechanism holding unit are arc-shaped, it is possible to enlarge the compression mechanism portion without changing the inner diameter of a sealing container, and to increase the ejected flow volume.
