Abstract: R404A refrigerant is one of the most widely used hydrofluorocarbons in the commercial refrigeration industry for low and medium temperatures. However, this refrigerant contributes negatively to the environment due to its ...

Abstract: In this study, the development of a physical model for a miniature refrigeration system is presented. The model is based on physical foundations and the incorporation of information provided in the manufacturers’ catalogs. ...

Abstract: A solar radiation model is applied to a low temperature water-in-glass evacuated tubes solar collector to predict its performance via computational fluid dynamics (CFD) numerical simulations. This approach allows obtaining ...

Abstract: A transient study of the cooling process inside a cabinet is presented in this work. Computational fluid dynamics (CFD) is used to obtain the transient temperature of the air inside a small cabinet. Three cooling levels, ...
