The efficiency of a gas heat exchanger is governed by various factors, including temperature difference, flow arrangement (counterflow, parallel flow, or crossflow), and the material properties of the heat exchanger itself. For instance, counterflow arrangements, where the two fluids move in opposite directions, typically yield higher efficiency compared to parallel flow arrangements. This is due to the greater temperature gradient maintained across the heat exchanger, which facilitates more effective heat transfer.
