Abstract:
1. An appliance comprising: a cabinet having an internal volume and comprising a first compartment having an internal volume spaced within the cabinet and operating at a first compartment evaporating pressure and a second compartment having an internal volume spaced within the cabinet and operating at a second compartment evaporating pressure where the first compartment and the second compartment within the cabinet are separated by a vertical mullion to form the first compartment and the second compartment within the cabinet and wherein each compartment has at least one access door that only accesses that compartment and the overall cabinet has a steady state total heat gain and the first compartment has a first compartment steady state heat gain and wherein the first compartment evaporating pressure is higher than the second compartment evaporating pressure; a coolant system comprising: a single compressor operably connected to at least one evaporator where the single compressor is the only compressor associated with the appliance for regulating the evaporating pressure and a temperature of the first compartment and the evaporating pressure and a temperature of the second compartment; a shared coolant fluid connection system that interconnects at least the single compressor and at least one evaporator; a coolant fluid spaced within the shared coolant fluid connection system used to regulate both the temperature of the first compartment and the second compartment; and wherein the compressor provides the shared coolant at at least two different pressures to at least one evaporator using the shared coolant fluid connection circuit; wherein the ratio of the steady state heat gain for the first compartment to the steady state total heat gain for the overall cabinet is about 0.50:1 or greater.
