  • Alternate path for refrigerant flow on a split system icemaker
    Publication number: 20020095944
    Abstract: An ice-making machine and method that uses an accumulator to accumulate liquefied refrigerant when warm gasified refrigerant is supplied to the evaporator after a freeze cycle. During a harvest cycle, a set of valves operates to bypass the condenser and direct the discharged gasified refrigerant from the compressor through the accumulator and then to the evaporator. The warm gasified refrigerant converts the liquefied refrigerant to gaseous refrigerant. This enhances the suction pressure to the compressor during the next ensuing freeze cycle, thereby increasing the efficiency of the accumulator.
