The embodiment of the present application discloses an anti-surge system for a refrigeration station and a compressor unit, the anti-surge system comprising: a centrifugal compressor comprising a gas outlet; a first gas path for receiving a section of gas, the section of gas being compressed by the centrifugal compressor to form first compressed gas; a second gas path for receiving first supplementary gas, the first supplementary gas being mixed with the first compressed gas and compressed by the centrifugal compressor to form second compressed gas; a third gas path for receiving second supplementary gas, the second supplementary gas being mixed with the second compressed gas and compressed by the centrifugal compressor to form third compressed gas; an exhaust gas path connected to the gas outlet, the exhaust gas path being used for discharging the third compressed gas from the anti-surge system; and an anti-surge gas path selectively connected to the first gas path, the second gas path and the third gas path, the anti-surge gas path being used for feeding the first compressed gas into the first gas path, or feeding the second compressed gas into the second gas path, or feeding the third compressed gas into the third gas path.
