Modelling of an ejector air-conditioning system: sizing and rating tools.

Author(s) : HEMIDI A., SEYNHAEVE J. M., BARTOSIEWICZ Y.

Summary

The PROFESSI project aims at optimizing an ejector air-conditioning system (EACS). This paper presents a detailed rating modelling of this system. This model can predict the EACS performances when this system is submitted to climatic conditions changes. The effect of a subcooler integration is studied as well. It was concluded that the subcooler must be bypassed when the external temperature goes beyond a critical temperature. Before this threshold, the subcooler improves the COP and cooling capacity. Moreover, a solution is proposed in order to keep the operation of the system even under off-design conditions through the use of a regulator heat exchanger.
