The use of certain types of depressants is one of the primary contributors to global warming and ozone depletion, the demand for effective and sustainable cooling systems has increased the use of ice slurry as a promising substitute in a variety of applications. But there is still much work to be done to produce ice slurry effectively. To improve the formation of ice crystals, the process, and overall system effectiveness, this study report presents an experimental examination of a mechanical scraper ice slurry generator using ethylene glycol, and propylene glycol as depressants at three different percentages, namely 10%, 18%, and 25%. The study comprises the measurement of several parameters at various state points, such as mass flow rate, pressure, temperature, and enthalpy, as well as the computation of performance parameters, the link between slurry temperature and time, and a comparison of the system's coefficient of performance (COP) at various concentrations. In this study, a –14.8°C temperature was attained for a 25% volume-by-volume aqueous solution of ethylene glycol, representing the lowest temperature recorded on our system.
