In this second international permeability benchmark, the in-plane permeability values of a carbon fabric were studied by twelve research groups worldwide. One participant also investigated the deformation of the tested ...
[EN] This article presents an analysis of the feasibility of R454C and R455A, two new low global warming potential (GWP of 148) refrigerants, in vapor compression refrigeration systems as alternatives to R404A for warm ...
[EN] This paper presents a detailed experimental analysis of the energetic effects of using a subcooler system in a two-stage refrigeration facility driven by a compound compressor. The analysis is carried out by comparing ...
[EN] The enthalpies of formation of the large pore pure silica beta polymorph C (BEC) and the extra-large pore
germanosilicate ITQ-33 zeolite are investigated by high temperature oxide melt solution calorimetry. The
enthalpies ...

[EN] Mobility management has become a great challenge due to the exponential growth in the
number of devices that can connect to home or visited networks, and the need for
providing seamless mobility in future generation ...
We present the experimental evaluation of an internal heat exchanger or suction-line/liquid-line heat
exchanger in a CO2 subcritical refrigeration plant with gas-cooler. The plant, driven by a 1.5 kW CO2 semi
hermetic ...
The Regulation CE-1005/2009 has banned the use of virgin HCFC-22 in Europe from the 31st December 2009, because it contains chlorine, although its use is allowed up to the 31st December 2014 if it is recycled. Now, ...
[EN] In this work an experimental evaluation of the working fluid HCFO-1233zd-E as HFC-245fa replacement in ORC systems for low temperature heat sources has been conducted. A fully monitored ORC module has been used to ...
