Abstract: The refrigeration system disclosed herein provides separate chilling and freezing compartments and operates in alternate phases. In the first phase, an evaporator which controls chilling compartment temperature also absorbs heat from a thermal mass through the change of phase of a liquid to a solid. In the second phase, this evaporator becomes a condenser for the operation of a second evaporator associated with the freezer component. During this second phase, the heat transfer is reversed, the fusion energy of the first phase is recaptured as melting energy in the second. Accordingly, heat is transferred from the second evaporator to the mass over a temperature differential which is less than that existing between the second evaporator and the environment.
