Thermal Energy Vs Geothermal Energy

Applications of solar thermal and geothermal energies are integrated with the purpose of utilizing renewable resources in low-carbon, energy saving manners. Geothermal and solar thermal energies are both clean, renewable energies with a huge amount of resources that are viewed as sustainable sources of energy storage [4]. Solar thermal energy is recognized as one of the best long-term options for heating and cooling energy supply. It has benefits such as it always helps to reduce primary energy consumption, it can be used as a hybrid with almost all kinds of back-up heat sources, and could be nearly everywhere with some limitations at very high latitudes. Thermal energy is a plentiful energy resource, which can be harnessed and stored as geothermal …show more content…
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
