Definitions
- NTM Low-temperature motor
- TTM low-temperature motor
- KM refrigeration engine
- the solution is a low-temperature heat engine, a low-temperature engine (NTM) or low-temperature engine (TTM), which can also be referred to as a cold engine (KKM), as described in the claims, which not only increases the thermal energy to the usual high, but also to can implement a low temperature level so that usable mechanical energy is obtained.
- a liquid gas is pumped to a higher pressure level in a closed circuit with a pump 1, then evaporated in an evaporator 4, relaxed in a relaxation machine 8 that delivers useful power, thereby cooled, liquefied in the relaxation machine 8 or in a subsequent expansion device 24 and kept ready in a liquid collector 10 for recirculation.
- a high-pressure circuit with the bypass line 45 and the bypass valve 44 is operated with liquid gas, which according to (FIG. 5) is supplied by a separate delivery rate from the pump.
- the pump only has to deliver the small volume of liquid while
- SPARE BLADE the expansion machine, for example a turbine that processes large gaseous volumes, but the volume ratio is still reduced in accordance with the set back pressure.
- the gas (boiling or condensation temperature and pressure) as well as the pressure and the pressure drop on the relaxation machine 8 and the temperature level are interrelated and must be matched to the vapor pressure curve.
- the pump 1 is driven by the expansion machine 8 via a separate motor 14 or from a power take-off.
- liquid gas In the liquid collector 10 on the low-pressure side, liquid gas must be at a pressure and a temperature at which the gas is liquid in accordance with its vapor pressure curve, so that this becomes
- the pump 1 with pressure valves 3 pumps a liquid gas from the suction or low pressure line 11 on the LP side into the kHD line 2 on the HP side and into the heat exchanger or evaporator 4.
- the pressure valves 3 ensure that no gas flows back from the kHD line 2 or the bypass line 45 if the pump design cannot prevent this. So much heat energy 5 is supplied to the evaporator 4 that the gas evaporates even under this increased pressure.
- the heat of evaporation required for this is absorbed by the evaporator 4 from the environment, from the air, water or other gases, liquids or solids or from a work machine. According to (Fig. 5), the thermal energy for evaporation can at least partly come from the gas itself by converting the rotational energy of the molecules and atoms into thermal motion.
- the performance of the air heat exchanger can be reduced to a minimum with insulated outer sides and closed and also insulated flaps or blinds.
- the devices for limiting the temperature of the evaporator 4 are controlled by a heat sensor directly or via a central control.
- the vaporized gas flows through the WHD line 6 through the throttle element 7 into the expansion machine 8. With the throttle element 7, the gas stream can be heated
- SPARE BL ⁇ 17 (RULE 26) HD line 6 can be reduced and also shut off.
- the pressure energy in the gas is reduced to the necessary counter pressure and mechanical work is carried out on the shaft 16.
- the gas gets colder.
- the complete expansion down to the low back pressure in the liquid collector 10 and the liquefaction should take place only after the further expansion stage in the expansion element 24 in order to avoid damage, for example due to cavitation in the expansion machine. Liquefaction can be facilitated by the back pressure.
- liquid gas is additionally expanded via the bypass line 45 and the bypass valve 44.
- the bypass valve 26 can also open automatically if the pressure in the wHD line 6 is too high, and it also serves as a high-pressure safety valve. If required, a preset portion of the pump output can also be discharged via the bypass line 45 and the bypass valve 44.
- the bypass valve 44 also serves as an overflow or maximum pressure safety valve if, for example, the pressure in the kHD line 2 or wHD line 6 increases due to the closing of the throttle element 7 as in the bypass line 45 and gas flows through the backflow preventer 43 into the bypass line 45.
- bypass lines 25 and 45 are also possible when the expansion machine is at a standstill in order to keep the machine cold and ready for operation.
- the pump 1 is switched on by a pressure or temperature monitor or also by a central control unit when the machine is at a standstill or the output of the pump 1 is increased when the machine is running in order to regulate the self-cooling .
- the pressure and temperature drop an opposite reaction is triggered.
- the liquid gas can be heated close to or completely up to the boiling point in the case of severe subcooling in an additional HP heat exchanger 29 after the pump 1, in order to thereby achieve cooling capacity e.g. to use for cooling purposes.
- An environmentally friendly generator that supplies one or more houses can enforce the decentralized power supply.
- the heating can also be done electrically instead of gas or oil. Electric heating instead of hot water makes house installation easier and cheaper.
- SPARE BLADE (RULE 26) The energy dependency on a particular country or region is eliminated. The nuclear hazard and harmful and disruptive high-voltage energy routes as well.
- NTM NTM

- ERSATZBLAH Low-temperature motor (NTM), low-temperature motor (TTM) or refrigeration machine (KKM)
- Heat exchanger or evaporator 4 is pumped, the power of which can be regulated and evaporated therein or in a plurality of heat exchangers, heat being absorbed by a heat source 5, for example heat from the ambient air or by a working machine 30, then through a wHD line 6 into a nozzle or a throttle element 7, which can be regulated and flows into a relaxation machine 8, is relaxed there and does work, and after the relaxation machine 8, directly or through an additional relaxation stage in a relaxation element 24 in the LP line 9 in a liquid collector 10 flows, and characterized in that by means of a bypass line 25 (FIG. 4) in a parallel circuit past the expansion machine 8, the expansion of vaporized gas in a expansion element, the bypass valve 26 (FIG.
