Hybrid model of absorption refrigeration system components

Absorption refrigeration system is a nonlinear process with strong interactions among each working device. It is of practically significance to develop a accurate and reliable model for real-time optimization and performance monitoring of overall system. The hybrid modeling approach take advantages of both physical and empirical modeling approaches. The model is robust and gives a better match to real performance over the entire operating range. The hybrid model of absorption refrigeration system components (evaporator, condenser, heat exchanger etc.) are analyzed in the paper. The L-M method is used to identify the unknown parameters in the model, and lay the foundation for further optimization performance of system.
