Analysis of volume concentration of glycol and ethanol in refrigerants used in automobiles

Abstract

In the Ambato canton located in the highlands of Ecuador at 2,577 meters above sea level, different types of coolants are offered for engine cooling systems, for which the user looks at cost, quantity and quality. In addition, it analyzes the properties of the fluid, to keep the engine temperature regulated. There are a large number of refrigerants currently used in commercial and industrial applications. Each refrigerant has properties that differ from others, such as: boiling points, specific heat, latent heat, density, and other factors that affect the refrigerant's ability to maintain optimum operating temperature. Learning techniques and analysis of physical and chemical properties of various types of refrigerants used in the city were established. The freezing point of ethylene glycol-based automobile antifreeze in seven types of refrigerants was analyzed by refractometry method. According to the experimental design of multiple comparison tests, it was determined that the optimal coolant for a car is ACDelco, which will contribute in the future, minimize inconveniences or inconveniences in the car's cooling system, avoiding overheating and giving rise to unscheduled corrective maintenance.
