| Abstract： | Multistage vertical-type absorption heat transformer with LiBr-H2O solution as the working pair applied to the urban heat exchanger network stations was used as research object. By establishing a three-stage steady-state model through lumped parameter method, the changes in the liquid level and stability across the pressure of the large temperature difference multistage vertical-type absorption heat transformer in actual running conditions were simulated and studied. The results of the simulation provided advices and guides for pressure design in crew compartment and solution filling volume. |
