Abstract
A drink station is provided with an alkaline filter cartridge in fluid communication with an ambient temperature water line provide alkaline water, and with a chilled water mixed with the alkaline water at a spigot to provide chilled alkaline water. A hot water heating element is located below the spigot so hot water flows upward for dispensing from the spigot, with a vent line between the heating element and spigot helping hot water to flow from the spigot to the heating element. A refrigeration system and a carbonation system is also provided. The refrigeration system uses the ice-bank technology. A submersible agitator pump improves heat exchanged between ice-bank and water by forced convection. The agitator pump operating based on the temperature of the drinking water. A figure eight evaporator coil can provide two cylindrical ice banks and two chilled water coils to increase the chilled water capacity.
