AWWA ACE58298

The conventional geothermal system is used for heating and cooling. Groundtemperatures are between 50 and 60%. These are closed loop or pump and dumparrangements. This paper discusses using potable water fromwater mains as a source of heat and cooling. This system uses the heat exchanger, theheat pump, and the air delivery system. Heat exchangers use 3 degrees oftemperature to achieve cooling or heating. The location of the heat exchanger can beeither on the main or in the building. The system on the main, a wrapped flat coppercoil around a stainless steel spool about 132 inches long, can be controlled by thewater utility. The heat exchanger in the building returns potable water after a heatexchange into the water mains. The potable water can be protected to preventcontamination from a heat exchanger.
