Patent ID: 6898947

Claim:
A heat exchange refrigerant subcool system that utilizes stored discharge water from an ice machine that is then pumped through a heat exchanger for subcooling a refrigerant that has already passed through the condenser of said ice machine, comprising in combination: a subcooler connected in fluid communication with the output of the condenser, enabling the refrigerant to flow in a first direction through said subcooler after first flowing through the condenser; and said subcooler connected in fluid communication with the output of a pump that pumps stored ice machine discharge water to directly flow through said subcooler from a bottom portion to a top portion in a second direction opposite to said first direction and then to discharge, said pump controllably pumps said discharge water through said subcooler for maximum subcooling effect; whereby said subcooler utilizes the pumped and flowing cold discharge water from an ice machine for providing maximum available subcooling to the liquid refrigerant of said ice machine.
