A new method for designing thermodynamic pipeline and its thermal insulation

On the basis of the fundamental principle of thermodynamic economics an analysis was performed of the working media transport process in a thermodynamic pipeline. As a result, obtained was an equation for calculating the annual total expenses allotted to the thermodynamic pipeline. Through an analysis of the effect on the above-cited annual total expenses of such factors as the thermodynamic pipe diameter and thermal insulation layer thickness the authors have come up with a new design method for the thermodynamic pipeline and its thermal insulation layer, the so-called synchronization design method. In addition, to lower the annual cost of transporting the working media in the pipeline, a formula has been proposed to calculate the optimal dimensions of the pipe diameter and thermal insulation thickness. The foregoing can serve as helpful reference data for relevant engineering design purposes.
