Byline: E. Torrella, R. Llopis, R. Cabello, D. Sanchez, J.A. Larumbe This paper describes a Second Law Analysis based on experimental data of a two-stage vapour compression facility driven by a compound compressor for medium and low-capacity refrigeration applications, which operates with the most usual inter-stage configurations (direct liquid injection and subcooler). The experimental analysis is performed for an evaporating temperature range between -36[degrees]C and -20[degrees]C and for a condensing temperature range between 30[degrees]C and 47[degrees]C using the refrigerant R-404A. The final results are compared with energy analysis from previous works. Additionally, a new criterion of equivalence between the simple vapour compression cycle and the two-stage compression cycle is given.
