Numerical studies of refrigerating liquid overfeed systems working with ammonia and R134a.

Author(s) : GARCÍA-VALLADARES O., PÉREZ-SEGARRA C. D., OLIET C., et al.

Summary

The global algorithm is based on the sequential resolution of the different elements of the system (compressor, evaporator, condenser, etc.). For each element, a simplified mathematical model based on global balances of mass, momentum and energy is used. For the evaporator and condenser, specially tailored lumped parameter models have been developed. In this way, global heat transfer coefficient and the flow configuration factor have been obtained. Two refrigerant working fluids, ammonia and R134a, were compared.
