85 : // PURPOSE OF THIS MODULE:
86 : // This module simulates the performance of the BLAST absorbers.
87 :
88 : // METHODOLOGY EMPLOYED:
89 : // Once the PlantLoopManager determines that the BLAST absorber
90 : // is available to meet a loop cooling demand, it calls SimBLAST
91 : // absorber which in turn calls the appropriate Absorption Chiller model.
92 : // All Absorption Chiller models are based on a polynomial fit of Absorber
93 : // performance data.
94 :
95 : // REFERENCES:
96 : // 1. BLAST Users Manual
97 :
98 : // OTHER NOTES:
99 : // The Absorber program from the BLAST family of software can be used
100 : // to generate the coefficients for the model.
