Abstract: This disclosure relates to a centrifugal compressor. In a first example, the compressor includes a first impeller provided in a main refrigerant flow path, a second impeller provided in the main refrigerant flow path downstream of the first impeller, and a recirculation flow path. In the first example, the recirculation flow path is provided between a first location and a second location along the main refrigerant flow path. The first location is downstream of the second location, and the second location is downstream of the first impeller. In a second example, the compressor includes an impeller provided in a main refrigerant flow path, and a recirculation flow path provided between a first location and a second location along the main refrigerant flow path. In the second example, the recirculation flow path includes a recirculation volute. Further disclosed is a method for operating a centrifugal compressor.

Abstract: An example refrigerant system according to an exemplary aspect of this disclosure includes, among other things, a refrigerant loop having at least a condenser, an evaporator, and a compressor. The compressor includes a motor in communication with a variable speed drive. The system further includes a cooling circuit including a pressure regulator downstream of a heat exchanger, the heat exchanger absorbing heat from the variable speed drive.
