Résumé

The experimental and numerical study on R410A air conditioning system with two-phase ejector were presented in this paper. An adjustable liquid–gas ejector based on a two-phase flow simulation model was designed and manufactured for experiment in the R410A air conditioning system. Both throat diameter (Dnt) and position (Dnm) of nozzle were studied under the given conditions. The experimental results showed that Dnt of 1 mm and Dnm of 4 mm yielded the best ejector efficiency and system EER. Nozzles with different Dnt and the adjustable ejector were also studied under different conditions. The experimental results showed that the ejector with adjustable nozzle can meet the requirements of different operation conditions. It was very useful for the future application of ejector in the air conditioning system.
