Title:
DUAL-MODE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2023/246204
Kind Code:
A1
Abstract:
Provided is a dual-mode compressor. The dual-mode compressor comprises a first scroll (31), a second scroll (32), and an impeller (33). The first scroll (31) and the second scroll (32) define a scroll compression working cavity (3a), and the impeller (33) defines a centrifugal compression flow channel (33d). The impeller (33) and the second scroll (32) are fixed relative to each other and are arranged coaxially, and the inlet of the centrifugal compression flow channel (33d) is communicated with the outlet of the scroll compression working cavity (3a). Under a large flow and high compression ratio working condition, the dual-mode compressor can work in a scroll-centrifugal compression mode, so that a working medium leaving the scroll compression working cavity (3a) can enter the centrifugal compression flow channel (33d) and then flow out of the dual-mode compressor, thereby solving the problems that a scroll compressor has low efficiency under a high compression ratio working condition, and a centrifugal compressor cannot compress a gas-liquid mixed working medium. Alternatively, in a small flow working condition, the dual-mode compressor can work in a scroll compression mode, so that a working medium leaving the scroll compression working cavity (3a) can directly flow out of the dual-mode compressor, thereby solving the problems of low efficiency and instability of a centrifugal compressor under a small flow working condition.
