Abstract

The invention of the power saving refrigeration device using gas motor is a gas motor series connection device that reduces the waste and loss of fluid energy by improving the installation configuration to improve the efficiency of using the air motor energy, which is a kind of fluid equipment, and energy due to heat transfer. High pressure gas with very low evaporation temperature and easy change of state instead of using non-condensable air in the fluid medium used to drive the air motor so that the transfer can be utilized by changing the state of the refrigerant material. By using the refrigerant to change the state characteristics of the high-pressure gas refrigerant represented by the heat transfer by the rotational power of the fluid device to configure the power saving refrigeration device using a gas motor to obtain a power saving effect as the power energy recovered.

First, the gas motor series connection device improves the energy utilization rate by changing the installation method from the parallel configuration of a single device to the serial configuration of a plurality of devices when using the air motor to improve the energy utilization efficiency of the air motor driven by compressed air. It is increased from 70% to more than 70%.

In a single device parallel configuration, which is a conventional method of using air motors, each air motor is driven while releasing compressed air into the atmosphere. At this time, the compressed air released into the atmosphere wastes a lot of fluid containing kinetic energy. The energy utilization efficiency actually obtained is very low, within 10% because it is forgiven for loss. In order to improve such low efficiency, when the installation method is changed to a series configuration and the plurality of air motors (the device of the present invention comprises 11 units) are connected and driven, the same operation as when driving one unit to the air motor outlet side of the last stage When a lot of compressed air is discharged, a plurality of air motors connected in series have the same flow volume and fluid velocity, so they are driven by the same rated rotational force to convert more power energy while consuming the same amount of compressed air. Will be. In order to reduce the energy loss generated in the part emitted to the atmosphere and the part sucked in, the circulation degree is cycled by connecting the outlet side of the air motor of the last stage and the suction side of the compressor, thereby minimizing energy waste and loss, and thus the energy utilization efficiency. It is a gas motor series connection device that can increase the efficiency of fluid equipment.

Second, the evaporation temperature is evaporated when the fluid medium used to drive the pneumatic motor in the gas motor is vaporized from liquid to gas instead of using air, a non-condensable gas filled only by the power of the compressor. It is low and absorbs the queue even at ambient temperature, so it has a high pressure and high pressure, and the air motor is driven by using a high-pressure gas refrigerant that can drive the air motor more strongly than compressed air.

It is possible to use heat transfer energy by driving air motor as high pressure gas refrigerant, which is connected to mechanical energy of circulating compressor power used to operate as heat pump, heat absorption of evaporator and heat release of condenser. By combining the effects of energy transfer to the system to help refrigerant circulation, it is possible to construct a complex device utilizing the principles of the Rankine cycle and the reverse Rankine cycle in a single device. While being utilized as a heat pump with a function of a heating device, the non-kinetic energy of the circulating fluid refrigerant can be recovered and used as power.

In order to efficiently use the non-kinetic energy of the fluid refrigerant circulated in the system of the high-pressure gas refrigeration system configured as a heat pump, a gas motor series connection device is installed to increase the energy utilization rate of the fluid equipment. By constructing a device that can recover the power energy and improve the energy utilization efficiency, it functions as a heat pump and at the same time obtains the rotational power of the fluid equipment, and the energy transfer effect of the heat transfer is the heat pump and power It is a power saving refrigeration device using a gas motor that can be applied to the existing high pressure gas refrigeration device and can be retrofitted and installed.

Description

Power saving refrigeration unit using gas motor

An object of the present invention is to provide a device that can efficiently obtain and utilize the power of the fluid device driven by the flow of the high-pressure gas refrigerant fluid, in particular to improve the installation method when driving the fluid device fluid of the same characteristics and the same structure It provides a method of improving energy use efficiency while using the device, and absorbs or releases heat by using a high-pressure gas refrigerant instead of using non-condensable air in the fluid medium that drives the air motor which is currently used. By changing the state as gas and liquid, the energy transfer according to the movement of the work is used as the rotational kinetic energy of the fluid equipment, and it is circulated inside the device that is used only as a cooling and heating device by applying it to the existing high pressure gas refrigeration system. A device that can be used as a power by driving a fluid device as a fluid refrigerant It is to provide a power-saving effect by the power energy recovered by the configuration, that is, to provide a power-saving refrigeration apparatus using a gas motor, which is a complex device that can perform the function of the heat pump and at the same time drive the fluid equipment. .

In general, wind power, water wheels, steam turbines, gas turbines, air motors, and the like are used as devices that obtain power by using gas or liquid, that is, fluid flow.

Among these various fluids, windmills made by natural conditions and tidal waves made by water or aberrations or tidal waters using tidal waters are simple in principle and have a long history of use. It requires excessive cost to equip and operate various facilities, and requires a large space, and because the power that can be obtained after the operation is relatively small, it is not practically used much and it is used in the artificially created space. In order to increase the fluid flow rate and to drive the fluid device by using the power as a power it is a lot of practical use.

The air motor of the present invention is generally used as a portable air tool in various industrial sites, but even the users are indifferent to use without thinking about the characteristics of the operation principle.

Compared to electric motors, air motors are smaller and lighter than electric motors, making them easy to carry and practical. Also, because they use compressed air, they are excellent in safety and can be damaged even if motor rotation stops due to overload. Although there are no flammable materials and there is no spark such as electric spark, there are many advantages that can be usefully used without risk of fire, while energy utilization efficiency is higher than that of the compressor that makes high pressure air. It is extremely low, less than 10%, and it is not widely used as a general power unit, power units on the deck of oil tankers where there is a fire risk due to the start of a special engine of a ship system or the generation of flammable gas, and portable pneumatic tools. It has been used only for special purposes.

In view of the various advantages of air motor, it is inevitable to expand the range of use by increasing the energy use efficiency of the device. Therefore, until now, air motor manufacturers have made much efforts to increase the utilization of a single device as a precision processing technology. However, the efficiency is only about 10% for developed countries such as Germany, Bosch and Japan.

Therefore, in the present invention, by improving the installation method of the existing fluid equipment in order to increase the energy utilization efficiency of the fluid equipment, it is possible to increase the energy utilization efficiency of only 10% to 70-80%.

In order to improve the energy efficiency of the fluid equipment, it is only possible to improve the method by comparing the principle of operation of the fluid equipment with each type and observing the phenomena occurring during the operation.

Compared with the steam turbine and the air motor, which are representative devices of the fluid equipment driven in gaseous state, among the steam equipment, the steam turbine and the air motor are both high pressure gas and the turbo rotor or the rotary rotor The principle in which a fluid is driven by pushing can be thought of as the same, but the process and energy source of making a high-pressure gas are different.

In other words, the energy source of the steam turbine or steam motor (which is a rotary machine of almost the same structure as the air motor) is heat transfer, and when water is heated to a temperature above 100 ° C from atmospheric pressure, the water boils and is heated at high pressure. The steam turbine rotor is driven by a strong pressure to drive the steam turbine. Even after the primary turbine is driven, the steam is at a high temperature and high pressure. Therefore, the steam turbine is continuously used as long as the temperature and pressure of the secondary turbine and the third turbine are maintained. It is driven by the method of increasing energy use efficiency.

However, since the ambient temperature, which is the atmospheric temperature, is very low compared to the steam temperature of high temperature and high pressure, the steam of the high temperature and high pressure that has been cooled rapidly to drive the turbine can be continuously driven because the temperature and volume decrease rapidly and the pressure is lowered. There will be no.

On the contrary, the air motor mechanically compresses the air in the atmosphere whose energy source is the non-condensable gas as the power energy, and stores a lot in a certain container to make the high pressure air in a state where the pressure is high.

The high-pressure compressed air made in this way passes the air motor through the pipe and releases it into the low-compressed atmosphere while driving the air motor. This type of air motor is used in the compressed air discharged to the atmosphere at high pressure and speed. It is a waste of much of the energy involved.

In the present invention, the first method of improving the energy utilization efficiency allows the use of the energy of the fluid flow using the series connection device rather than the gas in order to reduce the loss of fluid energy released into the atmosphere.

In order to understand in detail how to improve the utilization efficiency of fluid equipment energy as a gas motor series connection device, air in the air using an air compressor to drive the air motor in a single device parallel configuration, which is a conventional method of using air motors To the compressed tank and make compressed air more than 5㎏ / ㎠, and when the air is passed through the air motor and released into the atmosphere, the high-pressure air going straight forward pushes the rotor. In this case, the rotational force of the air motor is determined by the specific kinetic energy of the fluid flowing through the inside of the air motor (the mass of the fluid × the square of the fluid velocity × 1/2), but the conventional method of driving the air motor The torque that can be obtained from the air motor is within 10% of the specific kinetic energy of the high pressure air fluid. It is only a small amount. At this time, the high-pressure air released into the atmosphere is wasted as a loss because it is thrown into the atmosphere at a high speed with a lot of fluid kinetic energy (90% or more).

In order to actually calculate the energy utilization efficiency of the air motor driven as compressed air in the industrial field, the power required to fill a certain amount of compressed air and the actual consumption of the compressed air consumed while the air motor is driven at the rated output are calculated. It should be compared.

While the discharge direction of the compressed air of the air compressor is almost constant according to the rated power consumption, the consumption of the compressed air required to drive the air motor varies considerably according to the manufacturer's technical level and structure. This proves to be very different.

The following comparison table is a comparison of each manufacturer's products.

As shown in the above data, it can be seen that the average air consumption of compressed air consumed by the same output air motor is about 10-20 times higher than that of compressed air of the air compressor.

Pneumatic devices that use pneumatic motors are smaller, lighter than electric machines, and have many advantages in convenience, safety, and durability, but are not widely used because the energy use efficiency is too low, within 10%. Except in the case of the use is due to many restrictions.

The followings are the results of experiment to confirm the rotational force characteristics of the air motor according to the compressed air consumption of the air motor, and the method and the actual phenomena to reduce the energy loss and increase the energy utilization efficiency. It is constructed in stages and compared.

1 to 3 illustrate the comparative analysis of energy use efficiency by actual experiments.

The air motor used in this experiment is an air motor used in a grinder rotating at 10,000 RPM at a compressed air pressure of 5 kg / cm 2.

1 shows the use of the air motor according to the conventional method, in which air having a power of 10 times or more in order to continuously operate the air motor which is installed as a single device and discharged into the atmosphere and is driven at a rated speed of 10,000 RPM Compressed air must be continuously filled as a compressor to fill and fill the compressed air consumed by the air motor.

If the rated pressure is not formed due to the low output of compressed air, stop the air motor and wait without using compressed air.If the rated pressure is formed, open the compressed air supply valve to operate the air motor, and close the valve when the pressure is low. The stopping action must be repeated. In other words, the air motor cannot be used continuously.

At this time, when the air motor operates normally at the rated pressure of 5㎏ / ㎠, the air motor rotates at the rated speed of 10,000 RPM, and the gas flow rate (S) and the gas consumption per second (q) in the air motor are The air motor will operate normally while the tank pressure is maintained while maintaining a constant state.

In FIG. 2, the gas motor series connection device is changed to improve the energy use efficiency in order to compensate for the drawback of operating the air motor of a single device at 1 degree while using only 10% of the energy possessed by the fluid. It is an improvement.

At this time, there should be no leakage of air between the series connection devices than air, and when the air motor outlet connected to the terminal consumes the same amount of air as in the first degree, the gas of the air passing through the 10 connected air motors in series Since the flow velocity S is the same, the ten air motor torques are the same.

In this experiment, since the air resistance increased compared to 1 degree, in order to obtain the same rotational force, when the air pressure of the compression tank was increased by 10% from 5㎏ / ㎠ to 5.5㎏ / ㎠, it was rotated at the rated output.

It was found that the characteristics of the fluid pressure increase with increasing fluid resistance and the supply of pressure voltage with increasing electrical device resistance were different.

The energy use efficiency increased significantly, but energy loss appeared on the intake and discharge sides of the air.

In FIG. 3, in order to reduce the energy loss shown in FIG. 2, the fluid is directly circulated by connecting the suction shaft of the air compressor and the discharge side of the air motor to completely reduce the loss of energy generated by inhalation and release in the atmosphere. Will be.

The energy input to the air compressor will be available almost close to 100%.

All energy can be recovered except for mechanical losses.

By comparing the rotational force according to the gas consumption of the air motor, which is a basic device for the configuration of the present invention, the characteristics of the fluid rotating device can be summarized as follows.

[Experiment Result 1]

The gas motor rotational force of the same structure is determined by the moving speed of the gas flowing inside the gas motor, and the flow velocity of the internal gas depends on the pressure difference between the inlet side and the football side.

[Experiment 2]

If a gas motor of the same structure is connected and driven in series without gas leakage to the outside, the amount of gas flowing in the gas motor connected in series is the same, so the rotational force of all the gas motors connected in series is the same.

[Experiment Result 3]

Even if several gas motors of the same structure are connected in series, if the same amount of gas is sent to the exit side as driving one, all the series-connected gas motors rotate at about the same output as driving one. .

[Experiment Result 4]

When the gas motors of the same structure are connected in series, the resistance to the flow by the gas motor increases in multiples, but the resistance of the gas motor in the entire gas passage is relatively small. The same can be done, and all the gas motors can be driven at the rated rotational power.

[Experiment 5]

Gas motors are driven by using high-pressure gas refrigerant filled with the same pressure as non-condensable gas, and the rotational force is compared. It was able to drive a long time. (Because the high pressure gas refrigerant expands while absorbing ambient heat)

From the above experiments and results, it can be seen that a large rotational power energy can be obtained as it is possible to operate several air motors connected in series at rated rotational power while consuming the same amount of gas by adjusting the pressure difference between high and low pressures. It became.

The gas motor series connection device uses a conventional air motor, but can be used in a parallel configuration of a single device, so that the efficiency of energy utilization can be increased by reducing the energy loss emitted to the atmosphere without effectively utilizing the nonkinetic energy of the fluid. In this way, the installation configuration is changed and updated to achieve the circulation cycle of the fluid by installing and connecting the same air motors in series.

4 shows the installation system of pipes and valves as an opening diagram configured to utilize the gas motor series connection device in an industrial field.

This is a practical configuration diagram of a gas motor series connection device that operates or stops the air motor by passing the fluid passage through the air motor or by bypassing the 3-way valve.

As can be seen from the above experiments and results, by changing and improving the installation configuration of the existing air motor, the use of a gas motor series connection device consumes a small amount of compressed air, It is possible to obtain an incredible sum of torque output and fluid energy loss), and it is possible to increase the energy utilization efficiency of less than 10% to 70-80% more than 7 times when using the single device parallel configuration of the conventional method. This is a gas motor series connection device that can be used effectively and practically.

In the second step of the present invention, in order to construct a power saving refrigeration apparatus using a gas motor, in order to accurately understand the phenomenon of the physical state change of the energy use method according to the heat movement, the initial energy source inputted to obtain the power energy is dynamic. In preparation for the operating characteristics and structure of the air motor using compressed air, which is made by filling the air which is non-condensable gas by applying only the power energy, the initial energy source heats water as thermal energy to generate power by changing the state with high pressure gas. Compared with steam turbines, we need to find out how to find out the practicality of the differences and characteristics of the energy sources and find ways to put them into practical use. It is the same, but its structural and usage are the same as air motor. It should be understood with respect to the operating characteristics of the motor and the team structure.

Air motors (particularly referred to herein as gas motors or gas motors), which play a particularly important function in the present invention, are fluid devices made of a structure similar to steam motors, and have a structure and use characteristics with a gas turbine as an internal combustion engine or a steam turbine as an external combustion engine. This is a different device and is manufactured and sold with AIR MOTOR.

In order to construct a power saving refrigeration device using a gas motor, a gas motor series connection device made by supplementing an air motor is installed in a place where a fluid is circulated in a conventional high-pressure gas refrigeration cycle. In order to recover and use the non-kinetic energy with the rotating power of the gas motor, the gas motor series connection device should be installed and used so that the fluid inside the system does not leak.

Such a device for transferring heat energy and mechanical energy is applied in a conventional high-pressure gas refrigerating device or an air conditioner to absorb heat in a certain space, causing a change in the state of the fluid, and releasing heat to the outside while resetting the state of the fluid. It has been used only as a heat pump composed of a circulating cycle causing a change, but at this time, the high-pressure gas refrigerant was rapidly circulating and the non-kinetic energy of the fluid flowing inside the opening was not utilized.

The cooling device or the heat dissipation using simply absorbing heat was used only as a heating device and did not utilize the energy circulating in the fluid.

In the high-pressure gas refrigeration cycle, in the fluid cycle, the circulation system of the fluid refrigerant circulates the refrigerant by dynamic power by the refrigerant compressor, but at this time, the heat absorption and heat dissipation help the refrigerant circulation as heat transfer energy, thereby reducing the amount of heat in the compressor. It can be found that the results are shown.

Accordingly, it is possible to obtain the non-kinetic energy of the refrigerant fluid flow larger than the dynamic power energy input by the refrigerant compressor.

In the power saving refrigeration unit using gas motors, the refrigeration unit, which applies the principle of reverse-rankin cycle, which changes the state of the fluid refrigerant and causes the movement of heat energy by applying mechanical energy, is applied to the transfer of heat energy. This is the same principle as the steam turbine system in which the Rankine cycle principle, which causes the fluid movement to be made larger, thereby obtaining the rotational motion of the dynamic energy device, is applied in parallel with the reverse Rankine and Rankine cycles within the system of a single device. Will be utilized.

In the steam turbine used as a Rankine cycle, when heat is applied to the burner of a boiler, the high-pressure, high-pressure steam produced by evaporation of water from the evaporator drives the turbine. The energy transfer process in which the liquid refrigerant evaporates into the gas refrigerant and the fluid kinetic energy becomes larger while absorbing the ambient heat or the queue in the evaporator of the gas refrigerating device is a transfer system of the same heat energy.

In order to actually check the phenomenon that the energy transferred by heat transfer is added to the initially input power energy, the air conditioner manufactured by the manufacturer was compared and analyzed.

When the rated power consumption is 3.2 [KW] (when converted into calories, 3.2X860 = 2.752 [Kcal]), the cooling capacity can be absorbed and cooled by the heat quantity of 7.80 [Kcal]. Becomes larger.

It can be seen from the above comparison that the input energy is 2.752 [Kcal], and the energy input by heat transfer is more than 7.800 [Kcal], so the output of non-kinetic energy of the fluid refrigerant is more than 7.800 [Kcal]. It is a condition that can be recovered and utilized as energy.

In practice, however, 80% of the energy is used in consideration of losses, so that about 6.000 [Kcal] of energy can be recovered and recycled.

If this is misunderstood, the output energy is larger than the input energy of 2.752 [Kcal], which seems to deviate from the law of energy conservation. However, the result is that the energy transferred by the heat transfer is the state of the high-pressure gas refrigerant. This also results in the heat of the compressor, which means that the faster and more heat transfer of the evaporator and condenser, the more heat energy can be transferred and the more effectively the rotational power energy of the fluid unit can be obtained. .

Therefore, this phenomenon does not deviate from the law of energy conservation at all and is a physical phenomenon in which thermal energy is transferred by heat transfer.

In the power saving refrigeration apparatus using the gas motor of the present invention, while using as a refrigeration apparatus using a heat pump function, by using the heat energy which is a phenomenon appearing on the other side in a single system, the nonkinetic energy of the fluid refrigerant is increased to increase the dynamic energy power. The gas motor series connection device is installed in the system so that the energy saving refrigeration device using the gas motor is configured to improve the utilization efficiency and energy utilization efficiency of the device by combining the obtained devices.

In the conventional high-pressure gas refrigeration system, when the non-condensable gas is introduced into the circulation system of the fluid refrigerant, the refrigerant circulation compressor is overloaded due to a large amount of heat, so that excessive heat is generated in the motor, making it impossible to operate the refrigerator. It is often experienced in the midst.

As described above, the high pressure gas refrigerant has a low evaporation temperature and a high pressure gas refrigerant having a characteristic of easily changing state at room temperature transfers thermal energy quickly as a medium of a heat pump causing heat movement while circulating inside the system. By inputting energy, the refrigerant fluid can be circulated quickly so that the specific kinetic energy of the refrigerant fluid is increased.

The device of the present invention can be used as a cooling or heating device in a single system, and at the same time, it is a device that simultaneously performs a multi-purpose function to obtain and utilize the rotational power of the gas motor by using the flow of the fluid refrigerant which is inevitably made. It is a power-saving refrigeration unit using a gas motor to increase the utilization rate.

In FIG. 5, the gas motor series connection device, which is a part of the present invention device, can be installed in the high pressure gas refrigerant compressor so that the gas motor series connection device can actually operate in the existing high pressure gas refrigeration device. Piping and valves for the gas motor series connection are shown to check the refrigerant and to determine the operating conditions.

It consists of three valves and three connecting pipes on the discharge side and the suction side of the refrigerant compressor, so that the gas motor series connection device can be easily installed in the refrigerating device operating normally by adjusting the connecting pipe and the valve. One set of each device was installed to facilitate ease of installation and operation of the high pressure gas refrigerator.

6 is a system diagram for practical use of the gas motor series connection device as a power saving refrigeration device using a gas motor. The gas motor series connection device is installed in a conventional high pressure gas refrigeration device to prevent the non-kinetic energy of the fluid refrigerant. The apparatus which obtains and drives the compressor further installed by the rotational force power is shown.

The high-pressure gas refrigerant circulates the piping in the circulation cycle while absorbing or discharging thermal energy, causing a state change to a gaseous state or a liquid state.

Starting Compressor (CT) A compressor driven by an SMS electric motor (EM) that forms a high and low pressure differential at initial start-up to quickly circulate the refrigerant to drive the gas motors (G1-G11). When the gas motor (G1-G11) is driven at the rated rotational power by driving the self-compressor (G1-G11) mechanically connected to each gas motor (G1-G11), respectively, connected in parallel with the starting compressor (CT) Compressors (G1-G11) by compressing the refrigerant to help the heat of the compression of the starting compressor (CT) driven by the electric motor (EM) to reduce the time to drive the electric motor (EM) while the same amount of compressed heat to the refrigerant Since it is possible to form a cycle of circulation, it is possible to configure a power-saving refrigeration unit that saves electricity by reducing the time when using the electric motor (EM) while producing the same refrigeration efficiency.

The attached FIG. 7 is based on FIG. 6 to exchange the remaining work with each other in order to transfer heat energy more effectively to transfer the heat of the condenser that can be used as a heating device and the cooling state of the evaporator that can be used as a cooling device more effectively. The overall system diagram of a power saving refrigeration system using a gas motor further improves the condensation effect and further enhances the evaporator's vaporization effect, further improving energy use efficiency.

Another structure makes the heat transfer energy effect even more by exchanging the remaining heat energy as a heat exchanger by crossing the outlet pipe of the condenser and the outlet of the evaporator, and the gas motor (G1-G11) driven by the fluid refrigerant and its own compressor ( Shown is a coupling coupling K1-K11 for transmission of power connection which mechanically connects G1-G11) to transfer power energy.

6 and 7 show systems installed differently on the discharge side and the suction side of the starting compressor CT when the gas motor series connection device is installed. This is the gas motor (G1-G11) of the gas motor series connection device. When the non-kinetic energy of the fluid is obtained by the rotational power by the circulation of the high pressure gas refrigerant, it is applied to the existing high pressure gas refrigeration system. As a result of checking the structural characteristics and the state of refrigerant flow, it was confirmed that the installation on the discharge side of the compressor is suitable for obtaining energy efficiency.

However, since the high temperature is generated on the discharge side of the compressor, it is difficult to use the gas motor series connection device composed of the air motor used at room temperature, which is difficult to use for a long time, and it is difficult to completely seal the device.

In order to utilize the present invention in general, even if the design of the high-pressure gas refrigeration apparatus is changed and connected to the suction side of the refrigerant compressor, the gas motor generates the specific kinetic energy of the fluid of the high-pressure gas refrigerant according to the same operation principle. It indicates that it can be recovered by rotating power.

For example, it can be seen that the gas generator (air motor) in a prototype device configured similarly to a conventional air conditioner is driven by a strong rotational force even when a gas motor (air motor) with low energy use efficiency is installed. The gas refrigerant is easy to condense only when it loses heat and kinetic energy, so the gas refrigerant passed while driving the gas motor is lost in energy and flows into the condenser, which increases condensation efficiency and further improves the freezing cycle's refrigeration efficiency. .

Therefore, as described above, the present invention is utilized in the conventional high pressure gas refrigeration apparatus, while utilizing the function of the heat pump used for cooling and heating and the function of the apparatus which recovers the non-kinetic energy of the fluid with power, In order to maintain the proper temperature in the room and increase the use efficiency of the high-pressure gas refrigeration system, which increases the range of use for a pleasant life, the power saving refrigeration system using the gas motor can be configured to raise the principle of national economy and industry. It is a device that can be widely used in the phase.
