Definitions
- the invention relates to a standby generator operating with compressed air.
- Most of the current generator sets include an alternator responsible for producing electricity during their operation, driven by a diesel or other gas petrol engine. These engines are particularly noisy and polluting and consume an expensive energy which should be replenished frequently.
- the author has filed numerous published patent applications, WO
- the generator set according to the invention proposes to solve the problems linked to the fuel supply of the generator sets by using compressed air for its operation, it comprises a reversible compressed air engine which can operate either as an engine or as a compressor - compressed air motor-compressor driven by, or driving an electric motor also reversible and capable of operating as an alternator -motor-alternator-.
- the motor-alternator in electric motor mode, which receives its energy from an electric network for example that of the city, turns by driving the air-compressor motor-compressor then in compressor mode which fills, and maintains full, one or more high pressure compressed air tanks, for example 200 bars.
- the motor-compressor is automatically switched to motor mode and, supplied with energy by the compressed air contained in the storage tank (s), it drives the motor alternator which is also automatically switched to alternator mode to supply electricity.
- the transition from one operating mode to another is devolved to an electromechanical, electronic or other device.
- the emergency generator set according to the invention comprises an ambient thermal energy recovery system as described by the author in his patent application Nr FR 9700851, where the compressed air contained in the storage tank under very high pressure, for example 200 bars, and at room temperature, for example 20 degrees C, prior to its final use in the motor-compressor, at a lower pressure, for example 30 bars, is relaxed to a pressure close to that necessary for its end use, in a variable volume system, for example a piston in a cylinder, producing work which can be recovered and used by any known means, mechanical, electrical, hydraulic or other.
- This expansion with work has the consequence of cooling at very low temperature, for example minus 100 ° C., the compressed compressed air to a pressure close to that of use.
- This compressed air expanded to its operating pressure, and at a very low temperature is then sent to an exchanger with the ambient air, will heat up to a temperature close to ambient temperature, and will thus increase its pressure and / or its volume, by recovering thermal energy borrowed from the atmosphere.
- the engine operating method according to the invention comprises a thermal heating system as described by the author in his patent application FR 9800877, where he proposes a solution which makes it possible to increase the amount of usable energy and available characterized in that the compressed air, before its introduction into the combustion and / or expansion chamber of the engine, coming from the storage tank, either directly or after it has passed through the air and air heat exchanger and before its introduction into the combustion chamber is channeled into a thermal heater where it will further increase in pressure and / or volume before its introduction into the combustion and / or expansion chamber, thus considerably increasing the performance.
- the thermal heater can advantageously be supplied by said town gas.
- the emergency generator set according to the invention can be installed in a fixed position in buildings or other private accommodation. It can also equip a mobile group which will be supplied with electricity and will have its tanks filled before being used on external sites.
- the single figure shows a block diagram of the generator set according to the invention where the electric motor-alternator 1 supplied by the electric network by an electric cable 2 or supplying the electric network by an electric cable 3 driving, or being driven through a transmission 4, (by) the motor-compressor 5 which, in compressor function, fills a high-pressure storage tank 6 by a duct 7 and which in compressed air motor mode receives from the storage tank 6 compressed air which has been previously expanded, with work, in a variable volume device making it possible to considerably lower the temperature of the expanded air to a pressure substantially equivalent to the working pressure of the motor-compressor the trigger with work of the high pressure compressed air stored in the tank 6 is produced in a connecting rod 53 and working piston 54 assembly, directly coupled to a crankshaft 18C connected to the engine crankshaft 18 by a 21 A transmission.
- This piston 54 slides in a blind cylinder 55 and determines a working chamber 35 into which opens out on the one hand a high pressure air intake duct 37 whose opening and closing are controlled by a solenoid valve 38, and on the other hand an exhaust duct 39 connected to an air air heat exchanger or radiator 41 itself even connected by a conduit 42 to a buffer capacity at an almost constant final pressure of use 43.
- the solenoid valve 38 is opened and then closed in order to admit a load very high pressure compressed air which will relax by pushing the piston 54 to its bottom dead center, providing work, and driving the crankshaft 18C through the connecting rod 53 and through the has transmission 21 A the crankshaft of the motor-compressor 18.
- the exhaust solenoid valve 40 is then open and the compressed air substantially relaxed at operating pressure, and at very low temperature contained in the working chamber is discharged (in the direction of the arrow F) in the air air exchanger or radiator 41.
- This air will thus heat up to a temperature close to ambient and increase in volume by joining the buffer capacity 43 having recovered a significant amount of energy in the atmosphere.
- a thermal heater 56 consisting of burners 57 which will considerably increase the temperature and therefore the pressure and / or the volume of the compressed air in provenance (in the direction of the arrows F) of the air-air exchanger 41 during its passage through the exchange coil 58.
- the switching modes, the types of motor-alternator and motor-compressor, the design of the storage tanks and their volume can of course use known or unknown methods without changing the principle of the invention which has just been described.
