DEVELOPMENT OF A DYNAMIC SIMULATOR FOR DOUBLE-EFFECT COMMERCIAL STEAM ABSORPTION CHILLER

In spite of the great e!Torts that have been made to improve the efficiency of air
conditioning systems, the energy consumption for air conditioning has kept on
increasing. The demand for energy conservation has increased significantly. In order
to address these, there are increasing needs for research and development on
absorption chillers including reliability enhancement, energy saving control, and the
performance degradation identification. To find out the performance of absorption
chiller at the early development stage, experimental tests of prototypes of the chiller
were the only available method. Since absorption chiller of large capacity requires
huge power, the development of coefficient of performance (COP) and control
performance requires expensive test facilities, considerable time and cost. Therefore,
it is necessary to reduce the inefficiencies by applying a mathematical simulation
model using computational techniques.
