How does a cooling curve work
WebThe water-cooled chiller operates by circulating water or other fluids through the evaporator. The evaporator cools the fluid by transferring heat to the refrigerant. The … WebDetermination of Freezing Points Using Cooling Curves A cooling curve for a liquid shows graphically how the temperature varies with time as the liquid is cooled in a constant-temperature bath. The liquid is contained in a test tube and is stirred continuously to maintain thermal homogeneity. The rate of cooling is determined mainly by two factors.
