(57) Abstract:

The invention relates to the field of energy and is designed to produce mechanical or electrical energy, as well as the production of cold. Liquefied natural gas from the tank through the control valve on the supply line of the fuel fed into the gasifier, where through the throttle valve in the refrigerating chamber, cools the internal environment of the refrigerating chamber, in this heat with increasing pressure. Then in the vortex tube, the gas is divided into two streams, cold and warm, while the backbone of the cold stream is sent again into the cooling chamber, and highway warm flow through the heater into the turbine, where the expansion of the gas allows you to get extra power for the consumer. Exhaust gases from the engine Stirling highway exhaust gases pass through the heater. The purpose of cooling the Stirling engine is provided by the cooling system with coolant, in which the heat transfer with the environment (e.g., atmospheric air), and the pump, and the cooling system passes through the gasifier. The invention improves the efficiency. inverter direct cycle energoholding installation and poltinnik machines, operating on the Stirling cycle, is designed to produce mechanical or electrical energy and cold energy devices, stationary and transport Autonomous objects.

Known technical solutions for using liquefied natural gas as fuel in motor vehicles with internal combustion engines (ice), which includes the engine and the heat-insulated container with cryogenic liquid fuel. However, the transition to natural gas in internal combustion engines results in a drop in efficiency and the deterioration of the starting properties engines (Kershenbaum C. J., Falk C. E. Horizons transport equipment. M, Transport, 1988, page 109).

The well-known scheme of the refrigeration unit with vortex tube comprising a source of gas with higher pressure (compressor), a vortex tube, mainline warm flow with throttle valve, a line of cold flow (Theoretical fundamentals of heat and hladotehnika. H. 1. Engineering thermodynamics. Uch. the manual is edited by Professor E. I., great hotel. L. 1974, page 265).

Known power unit with Stirling engine and low fuel, comprising a container of liquefied gas.

Known energoholding installation, the supply line fuel heater, associated with the expansion turbine with the consumer power on the same shaft, and directed in a Stirling engine having a cooling system with a pump associated with the gasifier (EN 96116770 A1, F 02 C 1/04, 20.11.1998). However, in this device, the heater of the Stirling engine is placed in the combustion chamber, which reduces the durability of this node when operating on hydrogen fuel.

The technical result, which can be obtained by carrying out the invention is to improve the efficiency of the Converter direct cycle energoholding installation and additional useful energy.

To achieve this technical result highly effective energoholding installation, which includes the inverter direct cycle, thermally insulated tank with cryogenic fuel, such as liquefied natural gas), the supply line fuel shutoff and solenoid valves, throttle valve and the cooler (evaporator), supplied as a Converter direct cycle Stirling engine, cooling system, engine cooling associated with the environment, and the pump and line fuel supply, comprising regulating CL is on the highway cold and heat flows, the backbone of the cold stream is directed into the cooling chamber, and highway warm stream, consisting of a heater, an expansion turbine with the consumer power on the same shaft and the expansion tank is directed into the engine, while the exhaust gases from the engine flow through the heater and the cooling system of the engine through the gasifier.

The introduction of the highly effective energoholding installation of the Stirling engine, cooling system which is associated with the gasifier liquefied gas vortex tube with mains cold and warm streams, the first of which is directed into the cooling chamber, and the second - in is further provided with a heater and turbine with consumer power allows you to get a new property, consisting in the use of low-temperature fuel, first for partial cooling of the engine, and then to cool the refrigerating chamber, and after heat exchange with exhaust gases of the engine, as the working fluid to the expansion turbine, with additional energy.

The drawing shows a highly energoholding installation.

Energoholding installation consists of a tank with until 5, the refrigerating chamber 6, a vortex tube 7, the highway cold stream 8, line warm stream 9 with heater 10, the expansion turbine 11, which is located on the same shaft with the consumer power 12 and the surge tank 13, the Stirling engine 14, line of exhaust gases 15 passing through the heater 10. The Stirling engine 14 includes a refrigerator 16, the combustion chamber 17 and the cooling system 18 consisting of a cooler 19, associated with the environment, and pump 20.

Highly energoholding installation operates as follows.

Liquid cooling system 18 of the engine 14 is fed to the gasifier 4 line, fuel 2, in which, through the control valve 3 is supplied liquefied gas insulated from the tank 1. Transferring latent heat of vaporization of the coolant of the cooling system 18 in the gasifier 4, liquefied gas evaporates, expanding, throttled in valve 5 and is fed into the cooling chamber 6, where it cools the internal environment of the chamber 6 to the desired temperature, the heated pressure increase. From the cooling chamber 6, the gas enters the vortex tube 7, which is divided into two streams: cold and warm. Cold pogrebets to high temperature with increasing pressure due to heat exchange with exhaust gases of the Stirling engine 14. After the heater 10, the gas flows into the turbine 11, which, extending, doing more useful work to be passed to the consumer power of 12, and then through the expansion tank 13 is fed into the combustion chamber 17 of the engine 14. The exhaust gases through line 15 passes through the heater 10 and are removed from the environment. The purpose of cooling the Stirling engine 14 is provided, the cooling system 18. In this system, heated from the working fluid of the engine 14, the coolant from the cooler 16 by a pump 20 is supplied to the cooler 19, where the heat exchange with the environment (e.g., atmospheric air), while the coolant is cooled to ambient temperature. The liquid is then fed into the gasifier 4, where it is cooled to a temperature below the ambient temperature due to heat exchange with liquefied gas and is fed again into the refrigerator 16. Due to the heat exchange of the coolant with a low temperature and the working fluid of the engine 14 is reduced lower temperature cycle Stirling engine 14, which leads to increased efficiency.
