Study of the reconversion of a split with refrigerant R-22 to R-290

The paper presents an analysis linked to sustainable energy alternatives in terms of the use of refrigerants in air conditioning equipment, with the aim of achieving compliance with the energy agreements that will allow avoiding and reducing the risk of pollutant emissions into the atmosphere, saving energy, and contributing to more efficient methods in this equipment. A bibliographical analysis was carried out to contextualize the research, in addition to the experimental method through systematic observation in the reconversion processes, in this context, measurements of the experimentation carried out were taken, in addition to carrying out different tests to obtain the desired results. The conversion processes were evaluated as an alternative to the substitution of R-22, through the use of R-290, which resulted in a decrease in condensation pressure between 4 and 6%, a decrease in pressure drops between 13 to 19% in the condenser, and between 24 and 43% in the evaporator, contributing to a 6 to 10% decrease in the demanded power, directly affecting the energy consumption of the equipment, resulting in a decrease of the cooling capacity between 5 and 8%, this being insignificant for premises with commercial and domestic use.
