Absorption heat pumps of the type analyzed here provide process heat from waste heat. A simulation model with optimization capability for an advanced sodium hydroxide-water absorption heat pump has been developed. In this type of heat pump, increasing the area of the heat exchangers increases the dollar value of the process heat output, but it also increases the capital cost. The designer is then faced with the decision of how to allocate the heat exchanger area among the several heat pump components for optimal economic benefits. The optimization feature of the program allows the user to minimize the payback period for recovery of the capital investment in the heat pump. The computer program emloys proprietary software for the optimization. The program is relatively short, about 400 lines of Fortran, and can readily be used with different optimization subroutines if desired.
