Heat Exchanger Effectiveness (NTU method)

WebAug 9, 2024 · Counter flow heat exchangers are inherently more efficient than parallel flow heat exchangers because they create a more uniform temperature difference between the fluids, over the entire length of the fluid path. Counter flow heat exchangers can allow the "cold" fluid to exit with a higher temperature than the exiting "hot" fluid. WebA Counter-Flow Heat Exchanger is preferably used in exchanging energy from the geofluid to water in the geothermal system applications. In practice, there is no perfect heat exchange due to heat loss occurred during transfer. The actual heat transfer in the Heat Exchanger can be computed with Eq. 2.19.
