Producing cold at various temperatures, the ERS serves to save electric energy and reduce greenhouse gas emissions. The theoretical analysis of the ejector cycles carried out for various ERS has proved its capability to generate the cold at +12 °С to –40 °С, reaching the COP values at to respectively. bined cycles of water conversion, heat and cold production appear to be especially effective. Part 3 Introduction Gradual decrease of fossil fuels use for space heating and hot water supply became possible nowadays. the COP of solar thermal cooling system is less than 1. The COP of the latest solar collectors reaches 0,9 and the COP of the cold generators is still on a level of -. In order to keep the paces of civilization development and avoid its negative consequences, the global conception of the effective energy consumption should be significantly reviewed with a focus on renewable energy. The analysis of the renewables availability and particularities of transformation of the energy flows proved its optimal areas of application. PV panels are to be mainly applied for the
