Geothermal heating and cooling is a technology that uses the earth's energy to provide highly efficient heating and cooling for buildings. The systems use the constant temperature of the earth as the heat exchange medium instead of the outside air like an air source heat pump.
In the winter months, the system draws heat from the ground and transfers it inside buildings while in the summer it extracts heat from the buildings and transfers it to the ground.
There are many geothermal system designs, but common to all is a heat transfer fluid that must be measured to determine the system efficiency. Fluid flow rate, temperature and BTU’s are critical to efficient operation and Siemens process instrumentation has the required measurement devices to keep them running optimally.
