HOW DOES A NANOFLUID LIKE HYDROMX IMPROVE HEAT TRANSFER? June 30, 2022 By All HVAC systems consist of multiple heat exchangers. It has been academically proven that, during heat transfer, nanofluids increase the “active surface area” of the heat transfer fluid. As a result, the efficiency of the overall system improves as if the heat exchangers have become theoretically larger. Nanofluids increase the active surface area of the medium by evenly suspending nanoparticles. See this white paper for a more detailed discussion of the science of nanofluids.
