Evaluation of an educational prototype of Solar Cooling

Abstract

The main objective of this research is to evaluate the characteristic parameters of the operating process of a solar cooling prototype. It is a quantitative qualitative and descriptive research. The study sample is probabilistic. The instruments used were: the survey and a designed guide to collect data, pressure gauges, and thermocouples for temperature measurement and a solarimeter for radiation monitoring were installed. The results show that the variables of solar refrigerator dependent completely on the solar radiation , this because when this was greater , they manage to reach temperatures between 4 ° C and 6 ° C , required range for the maintenance and preservation of vaccines or other drugs used in health care centers, according to the of the students´ responses who were surveyed in the different courses of the Renewable Energies Engineering, having a solar cooling prototype for didactic purposes, is important because it can increase the knowledge by linking the theory received in classroom with the practice. The use of solar energy for the operation of a solar refrigerator, benefits students because they can do internships focused on these issues.
