| Abstract: | The paper defines a conception of virtual thermal system, and constructs the power-efficiency distributing matrix equation, which based on conventional thermodynamic methods, q-γ-τ matrix and equivalent entbalpy drop. The power-efficiency distributing matrix equation roundly reflects the effect of thermal economy on main system and assistant system, and each matrix has a explicit physical sense and strong regular form, which makes it simply, clear, objectively and convenient for programming in thermal system's calculation and local analysis. |
