CLI Postprocessing Welcome to the 2D Heat Transfer Solver, a powerful tool for finite element analysis of steady-state 2D heat transfer problems. This model contains a test harness that uses a Heat Exchanger (G-TL) block to model an air-water heat exchanger. In this example we estimate the transfer function for a heat exchanger. This value is the volume of fluid that is inside the heat exchanger at any point in time. The ground source heat pump uses R410a, a two-phase fluid refrigerant, as the working fluid. Third file is a test script that shows an example of using this function. This is attributed to the importance of determining energy costs and improving the energy recovery in chemical processes.
