METHOD OF COMPLEX USE OF GEOTHERMAL HEAT BY MEANS OF STEAM EJECTOR HEAT PUMP

摘要

FIELD: power engineering.;SUBSTANCE: invention relates to power engineering and may be used in systems of heat and cold supply with usage of geothermal heat with the help of a steam ejector heat pump. Substance: cooled coolant is supplied into a well, and heated one transmits heat to a consumer with the help of a steam ejector heat pump, besides, heat of the well in the warm period is used to generate cold for cold supply needs. In case of low or no loads of cold and heat supply they generate electric energy with the help of a turbogenerator, operating on the pair of coolant - low-boiling coolant, which is produced in the generator of the steam ejector heat pump, at the same time coolant vapours are sent to a steam turbine for generation of electric energy, and spent steam is sucked into a condenser of the steam ejector heat pump with a steam-jet ejector.;EFFECT: method makes it possible to reduce prime cost of heat and cold supply due to flexible mode of complex generation of thermal energy, cold and electric energy.;1 dwg
