Résumé

This paper presents effects of subcooling in condenser on efficiency of residential A/C systems in steady-state. To explore these effects, a system model with detailed component models was developed. The model was validated using experiments conducted on a typical 3 Ton (10.5 kW) system that used R410A. After validation, the model was used to evaluate the effects of subcooling in a range of operating conditions and several condenser sizes. The model results indicate that subcooling control can improve the system efficiency up to 8% for a given operating condition. Also, the improvements in efficiency are affected by condenser size. Smaller size of condenser results in greater potential for improvements. In addition, this paper presents a control strategy for achieving COP or cooling capacity Q maximizing subcooling as conditions vary.
