METHOD AND INSTALLATION FOR ACCUMULATING, STORING AND RETURNING OF MECHANICAL ENERGY

摘要

Inventions relates to power engineering and energy converters, are intended for accumulating, for instance, during generating excessive electrical energy, storing and returning during increased consuming of the electrical energy or returning of the mechanical energy for using in technological processes. Technical results of inventions: decreasing of dimensions and the cost of the energy accumulator, as well as decreasing of the cost of the energy accumulating, storing and returning method, simplifying and decreasing of the cost of the heat accumulators, being the part of the energy accumulator, maintaining the energy accumulator readiness for continuous cycling using. In methods of accumulating, storing and returning of the mechanical energy and in installations for their realizing three types of loops are used: the gaseous working medium loop, in which in the energy accumulating process it is realized the thermodynamic cycle of the heat pump with the gaseous working medium, but in the energy returning process it is realized the thermodynamic cycle of the heat machine with the gaseous working medium, another loop type - the loop of conventionally cold heat transfer fluid agent, being cooled in the energy accumulating process and being heated in the energy returning process, and the third loop type - the loop of conventionally hot heat transfer fluid agent, being heated in the energy accumulating process and being cooled in the energy returning process.
