Autonomous heat-cooling and power supply system based on renewable energy devices (trigeneration system)

The article presents the results of research on the possibilities of providing heat-cooling and electricity supply systems to autonomous consumers located far from centralized energy supply in the southern regions of Uzbekistan (Bukhara and Kashkadarya) based on renewable energy sources. In these regions, the average daily relative solar energy is 4.5 kWh/m2/day, the average wind speed is 5.5...8.5 m/s, the relative energy is 300...580 W/m2, and the underground low-potential temperature at a depth of 3...5 m, on average, is +10...+12oC. Analyzes of scientific research conducted on the development and reliability of trigeneration systems in the world are presented, and the possibilities of using these systems in our region are based. A combined solar-wind power plant, which is adapted to the climatic conditions of the southern regions of Uzbekistan, works efficiently in weak wind currents and high temperature regimes, and a complex energy system consisting of geothermal heat pumps that produce continuous heat and cold energy in different temperature regimes is offered. The proposed complex power plant allows for continuous and reliable energy supply to autonomous consumers located far from the centralized energy supply
