摘要： The present invention discloses a scroll compressor. At least two shrink belts (23′, 23″, 26, 26′, 28, 28′) are provided around the outer periphery of said fixed scroll between the outer periphery of said fixed scroll (2) and the inner wall surface of the upper cap (1) of the scroll compressor. The at least two shrink belts are annular, and are in interference fit between the outer periphery of said fixed scroll and the inner wall surface of the upper cap. The at least two shrink belts include a main shrink belt (23′, 23″, 28) and an assistant shrink belt (26, 26′, 28′). The main shrink belt and the assistant shrink belt are arranged side by side in the axial direction, that is, in the vertical direction of the fixed scroll, and the main shrink belt and the assistant shrink belt are spaced apart from each other by a distance. In this way, it is allowed to add other special structure (e.g., an additional fluid passage) to the fixed scroll, reduce the deformation of the fixed scroll, and improve the performance and the reliability of the scroll compressor.

摘要： Embodiments of the present invention provide a method for controlling compressor braking, a frequency converter and a variable speed compressor. The method includes steps of: determining to brake a compressor, wherein a brake circuit includes three switching units and the three switching units are respectively electrically connected to three phases of windings of a motor of the compressor; actuating two of the three switching units to short-circuit two phases of windings of the motor. The two phases of windings of the motor are short-circuited by controlling the three switching units to generate braking torque, such that the compressor is braked without introducing a DC voltage, and thus the braking energy consumption is reduced. Besides, by turning on only two switches at a time, the switching abrasion is reduced, and the overall service life of the three switching units is effectively improved.
