Use of low potencial wastewater heat

Abstract

The article points out that exhaustion of fossil stocks of fuel and negative impacts of fuel burning on environment determined a significant interest in technologies of heat utilization of low-potential sources in many developed countries of the world. Therefore the solution of the problem of using heat utilization technologies of low-potential sources will be of great importance for preserving people's habitats. In Russia, the most promising area of using unconventional energy sources is heat supply systems of houses and buildings. The conducted analysis shows that one of the effective directions of energy saving is heat pump systems of heat supply, using the most available low potential heat source of flooded massif of soil. It is noted that a huge energy potential of water pumped from closed mines is practically unused because of considerable distance of heat consumers from water purification complexes.
