)Theoretical Study of Geothermal Energy as Sustainable Heating Solution for ‘Jaref’ Elementary School)

Abstract

This study theoretically examines the geothermal energy resource as sustainable environmentally friendly renewable energy sources and energy source for the heat production using it in domestic practice. This paper illustrates the methods and the principles of operation of a geothermal energy from Jaref’s Well that potentially produces thermal energy for utilizing it in heating system in Jaref elementary school in extremely cold winter time; in addition, an analysis of the methods. These allow implementing the proposed project in the field of domestic heating with sustainable geothermal energy is approved and presents the benefits of utilizing geothermal energy in this application. 

This work is mainly based on real hot well data measured on the wellhead in Jaref area such as temperature (70oC) and volumetric flowrate (2.5 kg s-1) and well’s specifications, which has the potential to allow conducting domestic theoretical study of using geothermal heating systems for the well’s surrounding elementary school. Moreover, the work is based as well on some calculations for heat losses and examine the current fabric contributing in the targeted building in term of the heat isolation efficiency. These calculations’ results show, the school windows and door have the majority of heat loss within the system which 71%. These require further consideration such as replacing the current windows glass with double glazing windows. Thermal resistance of the pipeline per meter was also calculated which is found to be 0.25 watts m-1. However, when the well hot water flows in the pipeline, the heat loss is shows to be 6.825 watts m-1. The amount of heat transferred through radiation for the single classroom and for the whole area is 242 watts. Eventually, this practice will allow the authors of the current study have pinched conclusions about the potential of presenting such technic in the targeted region. At the end of this paper, the focal conclusions based on the finding of the study are clearly provided.
