Due to its global accessibility, renewable nature, low impact on the environment, and independence from meteorological conditions, geothermal energy is rising in popularity. Other forms of renewable energy, such as solar, wind, and tidal energy, are at a disadvantage given that they are dependent on meteorological conditions [4]. The energy harnessed from geothermal resources can be utilized in various manners including providing power generation, heating and cooling through indirect applications, and heating and cooling supplied by direct-use applications. Fluid stored at warm temperatures can be utilized when needed by running the fluid through a ground source heat pump in an indirect application which amplifies the heat to provide hot water. Alternatively, and additional indirect method would be to use stored cool fluid and feed it to a heat pump to run air conditioning [4]. …show more content…
Data was collected once per minute with an Ennovatis Smartbox. Temperature sensors were used for the measurement of the ambient temperature and the boiler-room temperature, and a solar irradiation sensor was also installed on the roof in the solar collector plane. Heat meters were used for monitoring the heat flow in the heating loop, the two buffer store charging loops, the domestic how water loop (DHW) and DHW circulation. Heat meters based on turbine type volume flow meters and Pt 500 temperature sensors for flow and return temperatures were used to measure the heat flow in the brine loops. Electricity meters for heat pump, electric heating element as backup, control, primary circulation pump, store charging pump, heating loop, fresh water station and DHW circulation pump were
