WebJan 1, 2016 · Description of Pinch point The occurrence of a pinch point may present a significant issue in the calculation of efficient heat exchanger designs in systems with identical working media and mass flow but different pressure levels on both the hot and the cold side, for a large range of temperatures. WebThe most accurate method to locate the pinch point is to apply the discretization method, which means dividing each heat exchanger into finite sections (50 segments, in this study) and conducting the energy balance in each section. Hence, the pinch point is located, and violation from the maximum temperature difference will be checked.
