TI  - ENERGY, EXERGY AND THERMOECONOMIC ANALYSİS OF A NATURAL GAS ASSİSTED GEOTHERMAL CENTRAL HEATING SYSTEM
AB  - In this work, a natural gas assisted geothermal central heating system in northwestern Turkey utilising low enthalpy geothermal fluid and natural gas as the sources for space heating was analyzed.The study comprised energy, exergy and thermoeconomic analyses of the system under hybrid operating conditions (i.e., from 1 January 2020 to 31 March 2020). The data were collected from a basis of the facility which operates the system. The values about the heat pumps were obtained from the department of the sales company in Istanbul, Turkey and the ‘Average Values for Hybrid Case’ were determined. This work covers energetically, exergetically and thermoeconomically assessment of the system in question through its all stages. The results were found with regard to the system performance investigation. The whole system efficiencies of energy and exergy were found as 56.77% and 49.93% respectively. The exergy cost value per hour and the thermoeconomic factor were calculated as 411.242 €/h and 9.8% respectively.
