Independent compartment temperature control of Lorenz-Meutzner and modified Lorenz-Meutzner cycle refrigerators.

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

Summary

Two dual-evaporator natural convection refrigerators, one refrigerating with a Lorenz-Meutzner cycle, were tested with a control scheme to provide independent temperature control of the freezer and fresh food compartments. A solenoid valve is used to switch the refrigerant flow either to a path that passes through both the freezer and food evaporators or to a path passing through only one of the evaporators. It was found that the solenoid valve, together with the temperature glide of the zeotropic hydrocarbon mixture and the additional refrigerant path, provided the desired level of temperature control in the compartments of the refrigerators. Energy savings are to be expected in comparison with CFC Rankine cycle.
