Geothermal Hot Water and Space Heating System in Egypt

Abstract

Direct utilization of geothermal energy

refers to the immediate use of the heat energy rather

than to its conversion to electrical energy. The

primary forms of direct use include heating and

cooling. Geothermal energy could be used to supply

hot water or could be used with a special equipment

(radiators) to make buildings warmer during winter

seasons. In general, the geothermal fluid temperatures

required for direct heat use are lower than those for

economic electric power generation. Most direct use

applications use geothermal fluids in the low-to

moderate temperature range between 50o and 150oC.

Although Egypt is not characterized by abundant

igneous activity, its location in the northeastern

corner of the African plate suggests that it possess

geothermal resources, especially along its eastern

margin. The data indicate that the temperature of 150

oC may be found in the reservoir in the gulf of Suez

and red coastal zone. This work designs a geothermal

hot water and space heating system to operate in

three buildings in a remote area in the Eastern Desert

(i.e. school, home & emergency hospital ) and

applies to the Umm Huweitat well(sample no. 69 on

the Red Sea approximately 20 km north of the city of

Safaga.) as a case study
