CLOSED ENERGY CYCLE AND HEAT ENGINE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC F01K23/02 

FIELD: thermal energy into mechanical energy converting.

SUBSTANCE: invention relates to the field of converting thermal energy into mechanical energy using substances that are in equilibrium in the liquid and gas phases as working bodies. The technical task of the group of inventions is to ensure the stability of the energy characteristics of a closed energy cycle. In a closed energy cycle, the first working fluid is used - an inert gas and the second working fluid - a liquid that is in the liquid phase at the beginning of the cycle, the first and second working fluids are fed to the compression phase, in which the liquid evaporates due to the compression of the inert gas during heat exchange between them through the walls of the heat exchanger, then the first working fluid is compressed, the first and second working fluids are sent to perform work, the second working fluid is cooled to the initial temperature, the first and second working fluids are returned to the beginning of the cycle. The temperatures of the first and second working fluids are measured at the end of the compression phase and, depending on the measured temperatures, the ratio of inert gas and liquid is adjusted when they are supplied to the compression phase. Argon is used as an inert gas, fluoroketone or freon is used as a liquid. The heat engine contains a first working fluid circuit formed by an air pump, an interloop heat exchanger, a heater, a first expander, and a second working fluid circuit formed by a pump, an interloop heat exchanger, a second expander, a refrigerator. Argon is used as the first working fluid, and fluoroketone is used as the second working fluid. Valves are installed at the inlet and outlet of the heater. Part of the air pump is the wall of the interloop heat exchanger (used as the wall of the interloop heat exchanger), for example, the air pump can be made in the form of a piston pump and includes a cylinder and a piston, the wall of the interloop heat exchanger is a cylinder.

EFFECT: increasing the thermal efficiency of a closed energy cycle and a heat engine.
