MATHEMATICAL MODEL FOR CALULATING INTERMEDIATE PRESSURE OF TWO-STAGE LIBR REFRIGERATING CYCLE
By analyzing the traditional thermodynamic calculation method and its inadequate, a new method through calculating intermediate pressure of two-stage LiBr refrigerating cycle to determine thermodynamic cycle is put forward. And a calculation model of intermediate pressure is introduced. The influence of heat source temperature, cooling water temperature and refrigerant water temperature on Δp is individually analyzed by computational simulation, the range of Δp could be obtained. The weight numbers of the factors that have effect on Δp are determined through a optimum method and a optimum model for calculating Intermediate pressure in Two-stage LiBr Refrigerating Cycle is proposed. As a result the thermodynamic calculation of two-stage LiBr refrigerating cycle may be simplified and optimized. Then, this cycle could be derived the highest thermodynamic coefficient.
