GEOCITY; geothermal district heating economics. [CDC CYBER74; CDC6600,7600; FORTRAN IV]

Technical Report ·
OSTI ID:6396160

GEOCITY is a large-scale simulation model which combines both engineering and economic submodels to systematically calculate the cost of geothermal district heating systems for space heating, hot-water heating, and process heating based upon hydrothermal geothermal resources. The GEOCITY program simulates the entire production, distribution, and waste disposal process for geothermal district heating systems, but does not include the cost of radiators, convectors, or other in-house heating systems. GEOCITY calculates the cost of district heating based on the climate, population, and heat demand of the district; characteristics of the geothermal resource and distance from the distribution center; well-drilling costs; design of the distribution system; tax rates; and financial conditions.CDC CYBER74;CDC6600,7600; FORTRAN IV; SCOPE 3.4.2 (CYBER74); At least 54K (decimal) words of memory are required. 104,000 (octal) words of program storage were used for execution of the sample problem on a CDC7600 and 137,000 (octal) words were used on a CDC6600.
