Energy converting device using vertical shock wave and method and cooling and heating system using same {Energy Converting Apparatus Using Vertical Impulse Wave, Method Eating and Air-conditioning System}

Conventional heating systems, such as boilers, use natural gas, diesel, kerosene, heat generated by using bituminous coal or anthracite as fuel, or heat energy generated by applying electrical energy to a heating coil.

In the combustion method, the cost of fuel increases with the depletion of natural fuel resources, and there is a problem that the exhaust gas generated after combustion causes pollution. Therefore, the heating cost is greatly affected by the increase in fuel cost, and the facility cost for purifying exhaust gas is added to increase the cost of the boiler apparatus.

In addition, since the electric boiler is a non-combustion method, there is an advantage that the device is simpler and does not generate exhaust gas than the combustion boiler, while the heating cost is relatively higher than that of the combustion boiler.

Moreover, although the combustion boiler and the electric boiler are different from each other, the energy conversion efficiency is generally about 70-80%, so a large increase in the conversion efficiency is not expected unless there is a change in the fundamental energy conversion method.

On the other hand, the method of using nuclear power, tidal power, or solar heat is difficult to extinguish on an individual or small scale because of the initial facility investment cost, and the method of using other waste oil or waste is also less practical because of the high cost of exhaust gas purification facilities. have.

Therefore, there is a need for the development of a new concept of energy conversion method and a new heating system using the same, which has a non-combustion type and excellent energy conversion efficiency like the electric boiler.

Moreover, in the related art, since heating and cooling methods are remarkably different from each other, it is impossible to use a cooling and heating system that can use this as a single device, and even if manufactured by diarrhea, the cost is very high and the conversion efficiency is low, thus maintaining maintenance cost Because of the high, there was a problem that it is difficult to spread in the home.

As described above, the reason why the energy conversion efficiency is high in the present invention is that the heat energy is hard to be converted to work energy (low efficiency), but the work energy can be converted to heat energy entirely (high efficiency) based on the thermodynamic law.

That is, the present invention converts the kinetic energy of the fluid into thermal energy by generating a vertical shock wave after passing the compressed fluid (gas) through the throat of the reduction / enlargement nozzle in a normal flow, etc. entropy flow method. As it passes through the throat of the nozzle and expands rapidly under the condition that does not occur, it lowers the temperature and pressure of the fluid and uses it for heat exchange with low temperature fluid to generate cold air or freeze the cooling water. A highly efficient heating and cooling system of the type 3N can be obtained, and furthermore, the system of the present invention can be implemented in an extremely simple, inexpensive and compact structure.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a schematic schematic diagram illustrating an energy conversion device according to the present invention, and FIG. 2 is a schematic cross-sectional view showing the shape of the nozzle shown in FIG. 1.

First, referring to FIG. 1, an energy converter according to the present invention includes a motor (M) 10 electrically operated, a compressor (COMP) 20 for compressing gas by a rotational force of the motor, and a compressor ( 20) When the compressed fluid (gas) passes through the throat in the normal flow isentropic flow method, a vertical shock wave is generated so that the kinetic energy of the fluid is converted into thermal energy, or a condition in which the vertical shock wave does not occur. A fluid consisting of a converging-diverging nozzle, so-called Laval nozzle 30 and a temperature change discharged from the nozzle 30, which lowers the temperature and pressure of the fluid when rapidly expanding through the nozzle. It consists of a heat exchanger 40 in which heat exchange is made suitable for each use.

The energy conversion medium, i.e., a gas which can be used as a fluid, is a non-explosive and stable gas that can be used even if compressed at high temperature / high pressure, such as air, nitrogen (N2), freon gas or inert gas, and is an inexpensive gas, for example For example, air is most preferred.

The compressor (COMP) 20 usable for the compression of the fluid can use any compressor, such as, for example, reciprocating, screw, turbo, scroll.

In general, the reciprocating compressor has a high compression pressure and may generate high heat in a short time, but has a disadvantage in that air discharge amount is small, discharge amount and pressure change is large, and noise and vibration are large. On the other hand, screw-type compressors have a constant discharge amount and compression amount, and are relatively larger than the reciprocating type, and have a low noise and vibration, and are particularly suitable for home appliances.

The reduction / enlargement nozzle 30 extends from the first diameter portion 31, the first diameter portion 31, which is the same as the outlet diameter of the compressor, as shown in FIG. 2, and the second diameter of which the diameter is gradually reduced. The part 32, the throat 33 formed at the end of the second diameter portion 32, the third diameter portion 34 whose diameter extends from the throat, and the fourth diameter portion having the same diameter as the first diameter portion. It consists of 35.

The installation of the nozzle 30 allows the maximum mass flow rate to flow ideally in the throat 33 of the nozzle so that the installation at the point sufficiently out of the required length of the discharge side of the compressor 20 is possible.

The volume or pressure value up to the inlet of the nozzle 30 is stagnant by the nozzle throat and the length is set so that the throat 33 has the maximum mass flow rate. )do. Therefore, the flow rate at the throat becomes Mach 1.

Preferably, the reduction / enlargement nozzle 30 may have a re-expansion tube 36 at its rear end for reducing the velocity of the fluid and raising the temperature / pressure.

The above-mentioned reduction / expansion nozzle 30 does not generate a vertical shock wave when the flow velocity of the fluid is accelerated to Mach 1-1.5 after passing through the throat 33, and the nozzle is accelerated to Mach 1.5 or more. A vertical shock wave is generated at the exit of.

Therefore, when the heat exchanger 40 is for cooling as shown in FIG. 3, the nozzle 30 passes through the throat 33 of the nozzle 30, and the flow rate of the fluid is between Mach 1-1.5. The diameter ratio of the same diameter part 31 and the throat 33 is set so that it may be set. When the heat exchanger 40 is for heating, the flow rate of the fluid after passing through the throat 33 of the nozzle 30 is Mach. (Mach) The diameter ratio of the same diameter part 31 and the throat 33 is decided so that it may become 1.5 or more.

That is, the nozzle 30 is used as the cooling nozzle 30a when the flow rate of the fluid from the throat 33 is set to Mach 1-1.5, and the heating nozzle when the flow rate of the fluid is set to Mach 1.5 or more. It is used as 30b.

Meanwhile, as shown in FIG. 3, the cooling heat exchanger 41 connected to the cooling nozzle 30a includes a heat exchange coil 41a through which a low temperature fluid discharged from the nozzle 30a passes and a heat exchange coil 41a to generate cold air. It may be composed of a blower fan 51 for discharging the air cooled by the outside.

In addition, the warm air heat exchanger 42 connected to the heating nozzle 30b is heated by the heat exchange coil 42a through which the hot fluid discharged from the nozzle 30b passes and the heat exchange coil 42a to generate heating air. It may be composed of a blower fan 52 for discharging the compressed air to the outside.

Moreover, the hot water heat exchanger 43 connected to the heating nozzle 30b is heated by the heat exchange coil 43a through which the high temperature fluid discharged from the nozzle 30b passes and the heat exchange coil 43a to generate hot water. It may be configured as a pump 53 for discharging the hot water to the outside. In this case, the pump 53 may be installed as necessary or may be omitted.

In addition, the heating heat exchanger 44 connected to the heating nozzle 30b is heated by the heat exchange coil 44a and the heat exchange coil 44a through which the high temperature fluid discharged from the nozzle 30b passes to generate hot water. It may be composed of a circulation pump 54 for circulating the hot water to the heating pipe (55).

For example, the hot water or heating heat exchanger 43 and 44 may use, for example, a plate heat exchanger or a bottom heat exchanger, and the plate heat exchanger may reduce the size of the system since the heat exchange is small and instantaneous. And quickly use the required heating or hot water.

In addition, since the cooling or heating fluid (air) discharged after the heat exchange discharged from the heat exchange coils 41a to 44a is not completely heat exchanged, the cooling or heating fluid (air) may be supplied to a required place through a filter or circulated to the compressor 56. .

The compressed fluid discharged from the compressor 20 may be selectively supplied to either the cooling nozzle 30a or the heating nozzle 30b depending on which heat exchanger 41-44 the user selects. 61, 62 can be controlled so that one or more of the heat exchangers 41-44 can be selected and operated.

4 shows, for example, a boiler system with a heat exchanger for heating and hot water in a 30-flat house.

In FIG. 4, the same parts are assigned to the same parts as those shown in FIG. To sum it up, part number 10 is a motor, 20 is a screw compressor, 22 is an air filter, 24 is an oil separator, 30 is a reduction / enlargement nozzle, 43 is a hot water heat exchanger, 44 is a heat exchanger, 54 Denotes a circulation pump, 55 denotes a heating pipe, 70 denotes an expansion tank, and 72 denotes a triangular valve.

The operation of the boiler system is substantially the same as the boiler portion of FIG. 3. The oil separator 24 is used to separate the compressed air from the oil because the compressor 20 is an oil type compressor, and the expansion tank 70 may expand the circulating water of the heating pipe 55 due to overheating. The three-sided 72 serves to absorb cold water at room temperature, that is, tap water, into any one of the expansion tank 70 and the hot water heat exchanger 43.

Therefore, hot water heated from the hot water heat exchanger 43 may be used, and the heating pipe 55 is heated by the operation of the heating heat exchanger 44 to heat the heating.

In the indirect heating system of the present invention shown in FIG. 4, a high heat conversion efficiency of 3.44 times as compared with the direct heating method of heating a direct heater with electricity can be obtained.

The present invention can be applied to various heat exchangers in addition to the above embodiments. For example, it can be used in any application such as a vehicle air conditioning system, a cold storage refrigeration system, a medical rapid cooling system.

In the above embodiment, an example in which the reduction / enlargement nozzle is used in one step is used, but the present invention is not limited thereto. For example, it may be configured as a two-stage reduction / enlargement nozzle connected in series. What is important here is that any nozzle can be used as long as it is a nozzle for heating that satisfies the conditions that can generate a vertical shock wave after passing through the throat of the nozzle.

Further, the ratio between the large diameter of the nozzle and the diameter of the throat must be determined according to the load connected to the heat exchanger and therefore cannot be limited to a specific value.

In the present invention, the cooling nozzles 30a and the heating nozzles 30b can be configured as required in the combination type as shown in FIG. 3 or the single type as shown in FIG. 4, and are connected to the respective nozzles 30a and 30b. Cooling or heating loads may also use air or water as the heat transfer medium.

Therefore, as shown in FIG. 4, the two heat exchangers 43 and 44 may be used for both heating and hot water, and a hot air heat exchanger 42 for discharging hot air may be used as needed.

Therefore, in the present invention, since it is not a combustion heating method, a simple heating and cooling system can be implemented and can be selectively operated according to a user's selection.

As described above, the present invention converts high kinetic energy of the fluid into thermal energy by generating a vertical shock wave using a compressed fluid (gas), or rapidly expands the nozzle by passing the nozzle under a condition in which the vertical shock wave does not occur. As a result of lowering the temperature of the fluid to be used for heat exchange with a low temperature fluid, a highly efficient cooling and heating system of no combustion, no fuel, and no pollution (3N) can be implemented in an extremely simple, inexpensive, and compact structure.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
