Abstract

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.
