A Study on Energy Conservation of Residential District Heating Using Geothermal Energy

Abstract

Based on the case studies of the residential district geothermal heating systems in Tianjin, this paper describes how to apply the theory and method of energy conservation in construction to various links of the heating source, the heating network and the heating consumer in geothermal heating system. Technical and economic comparison is made between direct supply and indirect supply in the geothermal heating system. This paper stresses the adoptable method of quantitative regulation and qualitative regulation. It also explains the way of comprehensive use of the geothermal water in many respects. In addition it discusses the design theory and technical method of heat metering. Finally, it summarizes the experiences of introducing advanced techniques and devices from foreign countries, and realizing the intellectual-control system.
