A set of experimental tests are presented on the effect of polymeric additives in water from the point of view of friction losses and heat transfer performance variations, in single passage, counter current, straight pipe heat exchangers. The tests performed on smooth, finned, and grooved pipes of different diameters show that the use of polymers in augmented surface heat exchangers is generally not advisable, but confirm also that thermal bus systems can take advantage from the use of drag reducing polymer solutions, provided accurate trade-off analyses are performed to get the best compromise between pressure losses and global heat transfer performances of the thermal loop.
