SOLAR COGENERATION SYSTEMS OF POWER-, HEAT-, AND COLD SUPPLY

Principal circuit decisions of solar cogeneration systems for the simultaneous production of electricity, heat (hot water), cold (evaporative chillers of gases and liquids), air drying, air conditioning (hydrothermal treatment of air streams) were developed. The inclusion of PV modules into the developed systems provides power to the fans and liquid pumps, significantly increasing the autonomy of the solar systems. Usage of available cold waste streams (in water coolers and evaporative air coolers) for PV modules cooling provides the growth of PV modules COP without additional expenses of energy on their cooling, that greatly increases the efficiency of not only the converters but also of the solar system as a whole.
