Abstract
The problem of correct selection of technological parameters for geothermal circulating systems is considered to ensure their effective functioning. The existence of the critical temperature of heat-carrier injected is shown, depending on well’s flow rate and diameter, ensuring reliable operating the geothermal circulating system. Optimization calculations for Thernair deposit of thermal water are carried out. In the calculations were taken account the temperature dependence of important characteristics, such as density and heat capacity of the coolant.
Keywords: geothermal circulation system; injected heat-carrier temperature; energy consumption; net power; viscosity; optimization.
