Peculiarities of the Use of Software System Thermal Scheme to Compute Heat Balance Diagrams

Drawbacks of the most known software systems used for the calculated analysis of heat balance diagrams were analyzed. A short description of the software program Thermal Scheme including the main peculiarities of it has been given. This software system allows us to carry out the calculated analysis of heat balance diagrams using the real properties of actuating media. A list of the elements the most frequently used for the calculated analysis of heat balance diagrams has been given. The equation systems that are used for the calculation of the elements of heat balance diagrams using the Thermal Scheme software system were also given. To demonstrate the opportunities of the suggested software system we carried out as an example the calculated analysis of the heat balance diagram used for a low-temperature separation of the natural gas using the turboexpander unit. The calculated analysis data on the estimation of material and power balances and thermodymanic indices of diagram elements were given for the diagram in question As a result using no manual selection we obtained the heat exchanger output temperature for the direct flow and the turbine output pressure when executing the power balance between the turbine and the compressor of turboexpander unit. It allowed us to curtail the time required for the calculated analysis. The given information demonstrates the advantages of the Thermal Scheme software system.
