Abstract:
1. An ice-making machine for use with a water supply and a beverage source, the ice-making machine comprising: an evaporator unit comprising an evaporator and a beverage dispenser, said evaporator being operably connected to said water supply, said beverage dispenser being in fluid communication with said beverage source; a compressor unit comprising a compressor; a condenser unit comprising a condenser; an interconnection structure comprising a plurality of conduits that connect said evaporator, said compressor, and said condenser in a circuit for circulation of refrigerant and forming of ice at said evaporator unit from said water supply; and a receiver connected in said circuit with said evaporator, said compressor and said condenser, wherein during a harvest cycle said interconnection structure selectively causes said refrigerant to flow to said receiver or causes said refrigerant to bypass said receiver, wherein said interconnection structure further comprises a head pressure valve and a bypass valve connected in said circuit with said compressor, said condenser, said evaporator and said receiver such that during said harvest cycle said receiver is either operable wherein said head pressure valve causes refrigerant to bypass said condenser so as to direct said refrigerant in vapor phase from said compressor to said receiver or said receiver is inoperable wherein said bypass valve causes said refrigerant to bypass said condenser and said receiver so as to direct said refrigerant from said compressor to said evaporator.
