Abstract
The results of numerical studies of thermodynamic effectiveness of the cascade thermal scheme of the heat pump plant are presented. The cycles` optimum parameters are defined for working substances –R407C and R134A refrigerants in the temperature range 20°- 105°С (68° - 221°F). The possibility of using heat pump plants in heating systems of traditional buildings in the temperature regime of 90°/70 °С (194°/158°F) in the presence of geothermal heat supply is shown.
