Optimization and experimental study on a transcritical CO2 heat pump system.

Author(s) : YANG J. L., MA Y. T., LI M. X., et al.

Summary

The major object function is brought forward to analyse the structure sensitivity for the CO2 heat exchangers. The major computation results based on the system show that the small diameter tube and long tube length should be selected in the CO2 transcritical cycle. And the simulation results of the new major system indicate that the COP and the cooling capacity increased on average 15 and 18%, respectively. Based on the optimization results and some existing problems in the primary system, the new heat exchangers and some related components are designed and manufactured in order to achieve rational structure and high efficiency operation, and then the new CO2 transcritical water-to-water heat pump system is set up. The experimental results show that the COP and the cooling capacity of the new system increased on average 30% or so, and the optimization object was achieved.
