Based on the corrosiveness,determined that geothermal heating with hot reservoirs of1000~1300m,1300~1600m,ought to adopt separately direct and indirect heating forms.
Applied value method of time and fund,the heating schemes of crest un-modulation and crest modulation when geothermal heating with hot reservoirs of1000~1300m,1300~1600m have been evaluated,and correlation with current heating scheme of boiler,thereby the geothermal heating scheme of crest modulation has been optimized.
The design tool for a geothermal heating system and it's application. A computer aided design tool for optimization of a geothermal heating system was developed.
In the thesis, the schemes of system, technical performance and economic performance were researched and analyzed through the Demonstration Project of the Geothermal Space Heating of Beijing University of Technology.
This article generally discusses conditions of geothermal resource and present situation of geothermal space heating in Beijing Plain, and analyzes the characteristics and advantages of the technology of geothermal space heating, and the“ bottle-neck”of restricting development and popularization currently. Sug- gestions are given in according with sustainable development of the geothermal resource in Beijing Plain.
This paper discussed the design criteria of material selection,the area of single unit,flow path,flow rate of a plate heat exchanger (PHE)in a geothermal heating system.
The design tool for a geothermal heating system and it's application. A computer aided design tool for optimization of a geothermal heating system was developed.
From the significance of adopting geothermal energy for heating,the application features of LonWorks technology are introduced. The structure of control system,the hardware and software design of field controller and the using of configuration software in host computer are expatiated. The control requirements are completed well.
The hydrogeothermal wealth of Bulgaria provides as important basis for the development of balneological and multi-seasonal tourism, bottling industries, geothermal heating of buildings and greenhouses, aquaculture and other related activities.
The results show that the effect of geothermal heating has about 70% of the magnitude of the vertical thermal diffusion and both terms cancel the advection term of the cold JBBW from the Japan Basin.
Above the eastern and western flanks, inversion of potential density was indicated in the bottom layers with an increase of potential temperature and a decrease of salinity, suggesting geothermal heating and outflow of ground water.
The (angle-integrated) geoneutrino flux has been shown to provide a unique probe of geothermal heating due to decays, and an integral constraint on the distribution of radionuclides in the earth.
Engineering studies show that geothermal space heating using even the lowest temperature geothermal aquifers (T ? 40 °C) in North Dakota and South Dakota is cost effective at present economic conditions.
