A heat transfer circuit that includes a main flow path for a working fluid that extends through a compressor, a condenser, an expander, and an evaporator. The working fluid includes CFI. The heat transfer circuit also includes an additive stream configured to supply additive for the CFI to the working fluid in the main flow path based on a discharge temperature of the compressor. A method for operating a heat transfer circuit that includes directing a working fluid including CFI through a main flow path of the heat transfer circuit. The method also includes changing a concentration of additive for the CFI based on a discharge temperature of the working fluid from the compressor.
