Résumé

The use of small diameter copper tube is an effective way to reduce refrigerant charge for R290 air conditioner, but may reduce system performance. To improve the performance of R290air conditioner with small diameter copper tube, this paper presents an investigation of application of a suction line heat exchanger. A theoretical analysis is proposed to investigate the effect of the suction line heat exchanger on capacity and coefficient of performance, and a simulation based analysis is processed to investigate the effect of suction line heat exchanger on refrigerant charge of condenser. To verify the results of analysis, experiments on a prototypeR290 air conditioner are carried out, and the results show that the suction line heat exchanger improves the cooling capacity by 5.3% and system efficiency by4.5%, and reduces the refrigerant charge by 6%, which agree well with that of the theoretical and simulation based on analysis.
