    Abstract: A refrigeration defrost system including at least one frosted evaporator having an evaporator refrigerant vapor line and an evaporator refrigerant liquid line, comprises a first compressor having a suction inlet line and a discharge outlet line each connected to a discharge manifold, the discharge outlet being connected to said evaporator refrigerant vapor line. A first pressure regulator valve disposed in a refrigerant bypass passageway between the discharge manifold and the suction inlet line, feeds refrigerant vapor, when a defrost cycle is required, from the discharge manifold into the suction inlet line. The refrigerant vapor is fed from the first compressor into the discharge outlet line and into the frosted evaporator through the evaporator refrigerant vapor line, thereby defrosting said frosted evaporator. Also disclosed is a method of defrosting a frosted evaporator using a single, dedicated defrost compressor.

    Abstract: First, a system for providing liquid refrigerant subcooling, subsequent to that subcooling accomplished by the primary condenser of an ice machine, by means of utilizing cold harvest and/or melt water discharge from said ice machine. Subcooling heat exchange to be accomplished by directing and controlling the flow of said harvest and/or melt water through some type of refrigerant to fluid heat exchanger, or by a passive heat sink method whereby the liquid refrigerant subcooler sits in a non-pumped open reservoir that overflows at each harvest cycle. This would provide greater refrigeration capacity to the ice machine system. Secondly, a system for providing hot gas discharge refrigerant precooling before said hot gas passes into the primary condenser of an ice machine, by means of utilizing the cold harvest and/or melt water discharge from said ice machine. Precooling heat exchange to be accomplished by directing and controlling the flow of said harvest and/or melt water through some type of refrigerant to fluid heat exchanger, or by a passive heat sink method whereby the hot gas discharge refrigerant precooler sits in a non-pumped open reservoir that overflows at each harvest cycle. This would provide lower power consumption, increased pumping efficiency of the compressor, decreased heat rejection to the ambient air surrounding the ice machine as well as improving the primary condensers performance. Next, a system that combines the first two systems described, that utilizes the cold harvest and/or melt water first in the subcooler, then reuses it in the precooler, for providing both the benefits of subcooling and precooling with the same harvest and/or melt water supply being used twice. Then, a system for providing inlet water precooling by utilizing excess refrigeration capacity provided by the subcooling to precool the inlet water supply to the ice machine. This would provide for increasing the ice machine's daily ice production capacity. Also, a system for providing ice storage bin chilling by utilizing excess refrigeration capacity provided by the subcooling to chill the ice storage chamber of the ice machine. This would provide for decreased ice loss to melting and would provide for retained ice quality. Finally, a system that would allow means to downsize the compressor size for an ice machine by taking into account the extra refrigeration capacity provided by the extra subcooling of the liquid refrigerant to the ice machine. This would provide for an ice capacity matched to the existing ice making plate as well as for reduction in power consumption per unit weight of ice produced.
