Experimental comparison of R134a and transcritical CO2 mobile heat pump and air-conditioning systems and the feasibility of a transcritical CO2 heat pump for a sport utility vehicle.

Author(s) : GIANNAVOLA M. S., MURPHY R., YIN J. M., et al.

Summary

The paper presents the results of the experiments conducted on a prototype R744 (CO2) system operating in a heat pump mode. The prototype system was sized for a compact car, to provide baseline for scale-up to sport utility vehicle size. This is the first experiment with transcritical CO2 heat pump reported in the open literature. Test facilities for such experiments and systems are described. The prospect of extending the operating range of a mobile AC system to a mobile heat pump operation appears promising.
