Abstract
Compared with traditional thought in thermal economic analysis, the inverse thought (i.e., "merged first, and analyzed later") is proposed. Based on which, combined with the equivalent heat drop method and q-γ-τ matrix form, the paper constructs the power-efficiency distributed matrix equation (PEDME) and does the preliminary studies of the thermodynamic system analysis based on this matrix equation. Its matrix structure is well correlated with the thermodynamic system, and there is element represented the thermal economy in the matrix equation, which overcomes effectively the problem of other thermal economic matrix equation requiring simultaneous equations on calculating the final thermal economic index. It is versatile and suitable for computerization. Numerical examples show this method is efficient. Figs 3,table 2 and refs 3.
