Patent ID: 7658082

Claim:
A heat transfer system comprising: a water line for carrying water having a first predetermined flow direction, said water line being in fluid communication with at least one water supply; a refrigerant line for carrying a refrigerant, said refrigerant line having a second predetermined flow direction opposite the first predetermined flow direction; a refrigerant evaporator in fluid communication with said refrigerant line; a vapor compressor in fluid communication with said refrigerant line; a refrigerant de-superheater in fluid communication with said refrigerant line and said water line; a refrigerant condenser in fluid communication with said water line and said refrigerant line; a refrigerant sub-cooler in fluid communication with said water line and said refrigerant line; an expansion device in fluid communication with said refrigerant line; wherein the refrigerant enters said refrigerant evaporator as a liquid and is warmed within said refrigerant evaporator to a cooled gas, and wherein the refrigerant enters said vapor compressor as a cool gas and is heated to a superheated gas, and wherein the refrigerant enters said refrigerant de-superheater as a superheated gas and is cooled to a hot gas, and wherein the refrigerant enters said refrigerant condenser as a hot gas and is cooled to a warmed liquid, and wherein the refrigerant enters said refrigerant sub-cooler as a warmed liquid and is cooled to a cooled liquid, and wherein the refrigerant enters said expansion device as a cooled liquid and is cooled to a bi-phase liquid, and wherein the refrigerant exits said expansion device and is passed to said refrigerant evaporator; and wherein the water enters said refrigerant sub-cooler and is warmed to a first predetermined water temperature, and wherein the water enters said refrigerant condenser at a second predetermined water temperature and is warmed to a third predetermined water temperature, and wherein the water enters said refrigerant de-superheater at the third predetermined water temperature and is warmed to a fourth predetermined water temperature, and wherein the water exits said refrigerant de-superheater and is passed to the at least one water supply at the fourth predetermined water temperature.
