Development and Indicators of Multifunctional Autonomous Plants Using Renewable Energy Sources

The autonomous plants using the solar and geothermal energy were developed and designed in ENIN. The plants are intended for solving the concrete regional problems and allow to lift the water from the sources or wells of different depth (up to 20 m and more), including the pure water and the water with particles or the brine, and supply also the steam and heated water to consumers in the places, which are remote from water supply and district heating system. The other purposes were: a removal of heat and chemical environmental impact, decreasing mineralization or desalination of mineralized water etc. The common feature of plants under consideration was the application of jet pumps (condensing injectors), which have the different constructions but combine simultaneously the vacuum and delivery pump as well as the condenser and heat exchanger. It was shown that in the conditions under consideration the use of such plants is economically profitable.
