Reconversión del R22 por R290 en acondicionador de aire tipo ventana para evaluar su razón de eficiencia energética en la ciudad de Guayaquil.

Abstract

In the work, an important review of updated scientific bibliography is carried out, which allows to summarize the most important aspects in terms of terms, concepts and procedures used for the conversion of air conditioning equipment. The fundamental properties of refrigerants are described, particularly R22 and R290, as they are the fluids used in this research. A window-type air conditioner with R22 is selected and instrumented and converted to R290, describing the procedure applied. It is evaluated under real operating conditions in the city of Guayaquil, the operating parameters are recorded and the main performance indicators are calculated, such as the demanded electrical power, cooling capacity and energy efficiency ratio to compare them before and after the reconversion. As a result, a slight decrease in refrigeration capacity of 1.6% was obtained, a decrease of 5.75% in the demanded electrical power and an increase in the energy efficiency ratio of 4.4%. Demonstrating the feasibility of the advantages of reconversion from the energy and environmental point of view.
