Abstract
Provided is a dual-mode compressor. The dual-mode compressor includes a first scroll plate (), a second scroll plate (), and an impeller (). The first scroll plate () and the second scroll plate () define a scroll compression working cavity (), and the impeller () defines a centrifugal compression flow channel (). The impeller () and the second scroll plate () are fixed relative to each other and are arranged coaxially, and the inlet of the centrifugal compression flow channels () is communicated with the outlet of the scroll compression working cavity (). When the dual-mode compressor works in different models, working medium leaving the scroll compression working cavity () can enter the centrifugal compression flow channel () and then flow out of the dual-mode compressor or directly flow out of the dual-mode compressor.
