论文简介： "A new tandem double-capillary tube refrigeration system for refrigerator-freezers is proposed. A
capillary tube was added between the two evaporators in
the fresh and frozen food storage chests to raise the
evaporation temperature of the refrigerating chamber,
and reduce the heat exchange temperature difference and
the available energy loss. Peng-Robinson (P-R) equation
of state was adopted to calculate the thermodynamic
properties of the refrigerants, and the available energy
analysis of the vapor compression refrigeration cycle was
programmed to calculate the thermodynamic performances of the new and the conventional refrigeration
cycle of the refrigerator-freezer. The calculation results
show that the available energy efficiency of the conventional refrigeration cycle of the refrigerator-freezer is
21.20% and 20.57%, respectively when the refrigerant is
R12 and R134a, while that of the double-capillary tube
refrigeration cycle of the refrigerator-freezer is 23.97%
and 23.44%, respectively. By comparison, the available
energy efficiency of the new refrigeration system
increases by 13.07% and 13.95%, respectively."
