Geothermal Heat Pump Systems of Heat Supply (GHPS): Operational Experience, Technical and Ecological Aspects in Russia

Abstract

This paper is devoted to the geothermal heat pump system of heat supply (GHPS) using the low grade thermal energy stored in the first 100 metres or so of the Earth. Data on the efficiency of long-term operation in the ground and climatic conditions of the Russian Federation of real buildings fitted with GHPS, installed by JSC " INSOLAR-INVEST " are submitted.
The second part of the paper is devoted to the technical and ecological aspects of the rational integration of GHPS into the power balance of Russia. Results of analytical research and numerical experiments are submitted based on the efficiency of various network decisions regarding the integration of GHPS into the structure of the centralized system of power supply prevailing in the country. Results of research and a method for defining the environmental component in tariffs for traditional power resources, that takes into account the costs to municipal budgets of environmental contamination from fossil fuel combustion are presented.
