Independent compartment temperature control of a modified-Lorenz-Meutzner-cycle refrigerator with a hydrocarbon mixture.

Author(s) : HAIDER I., SIMMONS K. E., KIM K., RADERMACHER R.

Summary

A dual-evaporator natural convection refrigerator operating with a modified Lorenz-Meutzner cycle was tested with a control scheme to provide independent temperature control of the freezer and fresh food compartments. A hydrocarbon mixture, 70% propane (R290) and 30% n-butane (R600) by mass, was used as refrigerant in the baseline and all subsequent tests. With the additional control devices, the daily power consumption of this refrigerator increased by 5.6% compared to the dual-evaporator mixture baseline. With its 12.1% net cycle savings compared to the conventional CFC-based Rankine cycle, this cycle refrigerator still showed a net 6.5% CFC-free energy savings potential.
