Abstract
An autocascade heat transfer fluid circuit includes one or more concentration sensors. The concentration sensors allow the determination of a current composition of a blended working fluid containing multiple components that separate during operation of the autocascade heat transfer fluid circuit. The current composition allows determination of a dew point for the current composition, and a superheat can be calculated based on the determined dew point and pressure and temperature readings. The determined superheat can in turn be used to control operations of the autocascade heat transfer fluid circuit by control of an expander thereof.
