I'm doing a project in which i must make a model of a geothermal heat pump, and since they obtain heat from water....i was just wondering.....................................ps it has to be save things, nothing like antifreeze or nuclear energy, and something i can easily obtain would be nice too
I think there is, I doubt you'd be able to get your hands on it though, Because it is very rare. Not many metal pieces can conduct heat from water.
Any substance having a temperature lower than the temperature of the water will transfer some of the water's heat to the particular material. A geothermal heat pump simply transfers the heat from the source to the place where it will be used. If your water is hot enough, all you'll be doing is heating a second medium and then using that second medium to carry the heat energy to the work area. Water at a lower temperature than the water at the geothermal source will work fine. After the transfer medium transfers its heat to your process, it will then be recycled at a high flow rate back to the geothermal heat exchanger to pick up additional heat energy and be returned to the work area's heat exchanger. All you need is a pump, enough piping to connect the pump to the heat exchanger inlet at the geothermal source, piping from the geothermal heat source heat exchanger outlet to the work area heat exchanger inlet, and then piping from the work area heat exchanger outlet back to the pump.
