摘要
A turbo chiller that can accurately determine the existence of surging occurring in a centrifugal compressor is provided. In a centrifugal compressor of a turbo chiller, which includes an impeller for compressing refrigerant, a resistance temperature sensor for detecting the refrigerant temperature is provided at the upstream side of the impeller. Accordingly, a temperature rise caused by surging can be detected and the existence of surging can be accurately determined.
