Experimental Study on the Performance of NH_3/CO_2 Cascade Heat Exchanger[J]. Journal of refrigeration, 2011, 32(4). DOI: 10.3969/j.issn.0253-4339.2011.04.072.
As the promotion and the application of NH3/CO2 cascade refrigeration system
the development of efficient cascade heat exchanger becomes more and more important to improve the performance of the system.Based on the experimental study of a NH3/ CO2 cascade refrigeration system
and the analysis of the effect caused by operating condition and the number of heat exchanger tubes on the temperature difference of heat transfer
