Description: Adding salt, glycol, or alcohol (antifreezes) to water reduces the freezing point. Thefeasibility of combining in onedevice, thechar acteristics ofboth icebuilder andsecondary refrigerant chiller forthe supply of coolant at a temperature below 0?C is discussed. The relative performance ofthree antifreeze solutions was tested using a small icebuilder andtheresults arepresented. Propylene glycol gave thebestperformance, achieving a finalsolution temperature between -3.2 and -3.6?C with rates of freezing comparable to those obtained with water. Calculated heat transfer rates and ice accumulation times are compared with the experimental data. Good agreement was obtained by adjustment of the convective heat transfer coefficient and the thermal conductivity of the ice.
