Abstract
A refrigeration appliance includes a cabinet having a trim breaker defining a mullion region and a refrigerant system. The cabinet defines a first compartment and a second compartment. The refrigerant system includes a refrigerant defining a flow path through a compressor, a heat loop coupled to the compressor, a condenser coupled to the heat loop, and an evaporator assembly coupled to the compressor and the condenser. The heat loop is routed around a perimeter of the cabinet and through the mullion region. The evaporator assembly includes at least one first evaporator disposed in the first compartment and a second evaporator disposed in the second compartment. The at least one first evaporator may include a first roll bond evaporator coupled to a second roll bond evaporator in series with the first, or a wire-on-tube evaporator.
