We demonstrate experimentally the energy and economic improvement of a domestic refrigerator, after only replace the original refrigerant R-12 (CFC) on the other ecological refrigerant R-134b (HFC). Commonly a refrigerator using CFC is replaced with new green refrigerator. However, in developing countries the residential sector has mostly refrigerators operating with R-12 and life exceeding 10 years use, despite the existence of international agreements that prohibit their use.  As a result we obtain that the refrigerator in evaluating operating with ecological refrigerant, compared with R-12 refrigerant source, stable thermodynamic conditions operation and lower power consumption compressor, for all load conditions and extended periods of operation is achieved. Therefore, one of the most convenient solutions from a socioeconomic view point, it is only replacing CFC refrigerant used...

Se demuestra de forma experimental la mejora energética y económica de una refrigeradora tipo doméstica, a partir de solamente sustituir su refrigerante original R-12 (CFC de característica contaminante y degradante de la Capa de Ozono), por otro refrigerante del tipo ecológico (HFC) como el R-134a. Comúnmente se practica el reemplazo de una refrigeradora que usa CFC, por otra unidad nueva que utiliza refrigerante ecológico de origen. Sin embargo, en países en vías de desarrollo el sector residencial mayormente cuenta con refrigeradoras que operan con R-12 y con vida de uso superior a los 10 años, no obstante la existencia de acuerdos internacionales que prohíben su utilización. El experimento consistió en: 1) preparación del equipo de refrigeración (dotación de reguladores de carga en el condensador y evaporador, dosificadores de refrigerante y aceite de lubricación-flu...
