Experimental investigation on the Reynolds dependence of the performance of branched heat exchangers working with organic fluids
The aim of this work is to continue the experimental evaluation of three different compact branched heat exchangers. To complete the previous study, additional experimental tests were carried out, using a commercial automotive refrigerant (Glycol) at different concentrations (50%, 100%). Finally, in order to have a deeper knowledge of this phenomenon and to identify the parameters regulating the heat transfer, an organic fluid has also been used and tested. The use of such a fluid has required a re-elaboration and design of the test bench.
