GEOTHERMAL USAGE FOR HOT WATER SUPPLY - A CASE STUDY IN VIETNAM AND RECOMMENDATIONS FOR GOVERNMENT MANAGEMENT
Main Article Content
Abstract
Geothermal is a stable, resilient, environment-friendly energy. This energy comes from the earth and can be harnessed for several aims, such as heating, hot water supply, agricultural drying, and electrical production. Because of arising from the earth, the hot water is stable and does not depend on the outside weather. Vietnam has a lot of places where geothermal energy can be exploited to save energy. However, this kind of sustainable energy isn not fully known and used. Moreover, Vietnam has no feasible policy to manage and exploit this energy. In this study, the hot water supply system for the resort in Binh Chau (in the South of Vietnam) was designed and the benefit of this was also concerned. Because the hot mineral water can not be directly supplied, the geothermal-hot water heat exchanger is used, and the code of which was written using the Engineering Equation Solver program. The results show that geo-thermal energy is one of the good manners to reduce the electrical demand, so Carbon Di-oxide emission is also reduced. In addition, policies for geothermal control in other countries are concerned and compared with the current situation in Vietnam. Then recommendations are provided to facilitate further the effective utilization of this sustainable energy in Vietnam.
