Energy and environmental comparison of two-stage solutions for commercial refrigeration at low temperature: Fluids and systems

Llopis, Rodrigo; Sánchez, Daniel; Sanz-Kock, Carlos; … - In: Applied Energy 138 (2015) C, pp. 133-142

International agreements will restrict in the near future the use of high-GWP refrigerants in Europe. These restrictions will favour the implantation of refrigeration systems with low-GWP fluids, especially in applications with high leakage rate. To clarify possible solutions that accomplish the...
