Metodología para el uso del R290 en sustitución del R22 en acondicionadores de aire tipo ventana ubicados en la Facultad de Educación Técnica para el Desarrollo de la UCSG para mejorar su eficiencia energética.

Abstract

In this titration work, as a general objective, it focuses on carrying out a methodological guide to replace the R-22 refrigerant with the R-290 in 24,000 btu window type air conditioners. For this, the behavior of both refrigerants was studied and analyzed. The methodology used was documentary, descriptive and explanatory. To analyze this behavior, we rely on the data and characteristics of each refrigerant as well as the Mollier diagrams, pressure / temperature tables, compatible oils, physical, chemical and thermodynamic characteristics. The properties of both refrigerants are reflected and the work of the compressor with both refrigerants is analyzed based on theoretical data. The steps to follow in the methodology for the conversion are considered, as well as the steps to follow when a device is not ready for the replacement of the refrigerant and presents damages such as leakage of refrigerant gas and broken compressor. It is expected that this work will contribute to the reuse of equipment that was designed to operate with R-22, improve energy efficiency and reduce the environmental impact generated by the use of refrigerants.
