The second law of thermodynamics demands that if we want to make a clock more precise – thereby reducing the disorder, or ...

Instead, [extremerockets] is building a miniature refrigeration unit, complete with a real refrigeration cycle.

Roughly three-quarters of our food passes through some kind of refrigeration on its journey from harvest to supermarket. Yet our understanding of that journey, the "cold chain" process, is a ...

This work presents the experimental evaluation of the energy performance of transcritical CO2 refrigeration and heat pump systems. The optimal gas cooler pressures and the optimal COP have been ...

Jin, Q., Xia, S. and Chen, L. (2023) A Modified Recompression S-CO2 Brayton Cycle and Its Thermodynamic Optimization. Energy, 263, Article ID 126015.

To meet the requirements of refrigeration, heating and cooling for residential, industrial, commercial and public applications, massive fossil fuels have been consumed and emit excess greenhouse gases ...

The present study introduces a methodology for mapping the thermodynamic losses of vapor compression refrigeration systems which consists of a theoretical model that splits the coefficient of ...

The present work is an investigation of refrigerating cycles and the compressors work for R134a and CO2/R744 refrigerants. Relative demonstration conferred has been peculiarly created design for small ...
