Description

High gravity gas cycle refrigeration system and method

technical field

The invention relates to the technical field of refrigeration, in particular to a high-gravity gas cycle refrigeration system and method.

Background technique

The traditional gas refrigeration cycle is divided into two types: the gas refrigeration cycle without phase change and the gas refrigeration cycle with partial phase change. The former represents the air cycle refrigeration system with air as the refrigerant, and the latter represents the carbon dioxide transcritical cycle refrigeration system. A typical air refrigeration cycle consists of two isobaric processes, an isentropic expansion and an isentropic compression process. The biggest feature of air cycle refrigeration is that the refrigerant does not pollute the environment, even if there is leakage, there will be no impact, and the refrigerated air can be sent directly to the air-conditioned room, saving the indoor heat exchanger and reducing the heat exchange temperature difference. At the same time, in order to further improve the system efficiency, a heat recovery cycle can also be used in the system. Usually, an air cycle refrigeration system requires an air compressor and an expander, both of which are coaxially arranged, and the expander transmits the work output during the air expansion process to the air compressor through the shaft to realize the recovery and utilization of the expansion work.

The disadvantage of the traditional air cycle refrigeration system is that the system efficiency is low, so high-efficiency turbomachinery should be used as much as possible, but this will reduce the technical and economic value of the system. The reason is that there are two conversion processes of shaft work-pressure energy and pressure energy-shaft work in the system. Since the work required by each process is much larger than the actual work required by the system cycle, each conversion The irreversible loss of the process will greatly reduce the system efficiency.

The fundamental way to improve the efficiency of the air cycle refrigeration system is to make the compression and expansion process have high efficiency, but it is difficult to achieve it with the usual shaft work-pressure energy conversion device.

A typical transcritical carbon dioxide refrigeration cycle includes an isentropic compression process, an isobaric heat removal process, a throttling process and an isobaric heat absorption process. Although carbon dioxide is also a good natural refrigerant, the carbon dioxide transcritical cycle usually has large overheating, low COP, and poor operating economy.

The patent with the application number 201510348645.9 proposes a supergravity refrigeration device, which uses supergravity rotation to realize the increase and decrease of pressure energy, that is, the mutual conversion between pressure energy and inertial potential energy is naturally realized when the refrigeration medium flows in the pipeline. Avoiding the traditional shaft work-pressure energy conversion process, the refrigerant medium only has flow loss, no disc loss, volume loss and dynamic and static conversion loss, and can also avoid or reduce throttling loss, so it can greatly improve the efficiency of the pressure boost/depressurization process Energy utilization efficiency, but the system is driven by an ultra-high pressure liquid pump, which is difficult to achieve in applications. The patent application number US5168726 (A) also proposes a similar system, which is also characterized by high-gravity rotation. For phase-change refrigerants, it assumes that the shaft work required for system operation is input from the rotating shaft, but according to the momentum moment According to the law of conservation, the shaft work input from the rotating shaft cannot be transferred to the working medium in the tube in this case, so the system actually has a principle error and cannot really operate.

For this reason, it is necessary to combine the characteristics of hypergravity technology with gas cycle refrigeration technology, so that it can avoid the use of expensive coaxial compression-expansion turbomachinery in air cycle refrigeration systems, improve energy recovery efficiency and system refrigeration efficiency, It can also be applied to a carbon dioxide transcritical cycle refrigeration system to reduce its superheat loss and throttling loss, thereby enhancing the feasibility of the gas cycle refrigeration system as a whole.

1.11 Drive the rotating spiral heat exchanger, dual-channel rotating tube 1 and dual-channel rotating tube 2 to maintain a certain rotational speed, thereby producing a supergravity effect in the refrigerant channel and cooling medium channel of the rotating spiral heat exchanger;

1.12 The air at normal pressure and room temperature enters the compressor inlet from the room through the refrigerant inlet pipeline. After being adiabatically compressed by the compressor, the pressure rises and the temperature increases. The channel inlet enters the refrigerant channel of the dual-channel fixed tube 1, and then passes through the dual-channel fixed tube-refrigerant channel outlet, passes through the rotary joint 1 and the dual-channel rotary tube-refrigerant channel inlet enters the refrigerant channel of the dual-channel rotary tube 1 Then, from the outlet of the dual-channel rotating tube to the refrigerant channel, through the inlet of the refrigerant channel, it enters the refrigerant channel of the rotating spiral tube heat exchanger. Under the joint action of pressure difference force and inertial force, the air is The refrigerant channel of the tube heat exchanger flows spirally outwards, is gradually compressed by the centrifugal force, and the air pressure rises. At the beginning, the air temperature is lower than the temperature of the cooling medium in the cooling medium channel of the adjacent rotating spiral tube heat exchanger. , the air will absorb the heat from the cooling medium in the cooling medium channel of the adjacent spiral tube heat exchanger, and the air temperature will gradually increase to the temperature of the adjacent cooling medium under the action of compression and heat absorption. After that, When the air flows in the refrigerant channel of the rotating spiral tube heat exchanger, it will continue to be compressed, but it will release heat to the cooling medium in the cooling medium channel of the rotating spiral tube heat exchanger, so that the temperature of the refrigerant during the compression process is always It will not overheat a lot. When the air reaches the outlet of the refrigerant channel, the pressure reaches the maximum, and the temperature is slightly higher than the temperature of the cooling medium at the inlet of the cooling medium channel;

1.13 The air flows out from the outlet of the refrigerant channel, and flows adiabatically through the pipeline to the inlet of the second refrigerant channel of the dual-channel rotating tube. The pressure continues to decrease, the inertial potential energy increases, and the temperature continues to drop. When it is imported, the air pressure is reduced to normal pressure, and the temperature is lowered to be lower than the air in the room, becoming low-temperature air at normal pressure. Then enter the refrigerant channel of the dual-channel fixed tube 2 through the inlet of the refrigerant channel of the dual-channel rotating tube 2, the rotary joint 2 and the inlet of the refrigerant channel of the dual-channel fixed tube 2, and finally enter the refrigerant channel of the dual-channel fixed tube 2 The refrigerant channel outlet enters the refrigerant outlet pipeline and flows into the room;

2.15 The cooling medium enters the cooling medium channel of the dual-channel fixed tube 2 through the external cooling medium inlet pipeline through the dual-channel fixed tube 2 cooling medium channel inlet, and then passes through the dual-channel fixed tube 2 cooling medium channel outlet, the rotary joint 2 and the dual channel in sequence The inlet of the cooling medium channel of the rotating tube 2 enters the cooling medium channel of the dual-channel rotating tube 2, flows out from the outlet of the cooling medium channel of the dual-channel rotating tube 2, and flows adiabatically through the pipe to the cooling medium channel inlet located at the edge of the rotating spiral heat exchanger , the pressure of the cooling medium increases, the temperature remains basically unchanged, and the inertial potential energy decreases;

2.16 After the cooling medium enters the cooling medium channel of the rotary spiral heat exchanger from the inlet of the cooling medium channel, under the joint action of pressure difference force and inertial force, the cooling medium flows spirally inward in the cooling medium channel of the rotary spiral heat exchanger, The pressure gradually decreases, and at the same time the cooling medium absorbs the heat of carbon dioxide in the adjacent refrigerant channel in the rotating spiral tube heat exchanger, the temperature of the cooling medium increases, and the inertial potential energy increases. When the temperature of the cooling medium increases above the temperature of the adjacent carbon dioxide, it will Discharge heat to the adjacent carbon dioxide, lower the temperature, and then the cooling medium enters the cooling medium channel of the dual-channel rotating tube one through the cooling medium channel outlet and the dual-channel rotating tube-cooling medium channel inlet; then passes through the dual-channel rotating tube-cooling medium channel in turn The outlet, the rotary joint 1 and the inlet of the dual-channel fixed pipe-cooling medium channel enter the cooling medium channel of the dual-channel fixed pipe 1, and finally flow back to the external cooling source from the outlet of the dual-channel fixed pipe-cooling medium channel through the external cooling medium outlet pipeline;

2.17 The temperature of the cooling medium flowing back to the external cooling source decreases after the external cooling source releases heat, and then re-enters the second cooling medium channel inlet of the dual-channel fixed pipe through the external cooling medium inlet pipeline, and circulates like this.

As an improvement to the hypergravity gas cycle refrigeration method of the present invention:

2.12 Low-pressure and low-temperature carbon dioxide gas enters the compressor inlet through the refrigerant inlet pipeline. After being adiabatically compressed by the compressor, the pressure rises and the temperature increases, and then flows out from the compressor outlet and enters the heat release channel of the cooler. The carbon dioxide gas is cooling The heat release channel of the cooler releases heat to the cooling medium in the heat release channel of the cooler, the pressure remains basically unchanged, and the temperature drops, and then the cooled carbon dioxide gas enters the dual channel fixed pipe through the inlet of the refrigerant channel of the double channel. The refrigerant channel of tube 1 enters the refrigerant channel of dual-channel rotary tube 1 through the outlet of the dual-channel fixed tube-refrigerant channel, the rotary joint 1 and the inlet of the dual-channel rotary tube-refrigerant channel in sequence, and then from The outlet of the dual-channel rotating tube—the outlet of the refrigerant channel enters the inlet of the refrigerant channel. Under the joint action of pressure difference force and inertial force, carbon dioxide gas flows spirally outward in the refrigerant channel of the rotating spiral tube heat exchanger, and is absorbed The centrifugal force gradually compresses, the pressure rises, and at the same time releases heat to the cooling medium in the cooling medium channel of the rotating spiral tube heat exchanger, so that the temperature of the carbon dioxide during the compression process will not be overheated much. When the carbon dioxide reaches the refrigerant at the edge When the channel exits, the pressure reaches high pressure, becoming high-temperature and high-pressure carbon dioxide, and the temperature is slightly higher than the temperature of the cooling medium at the inlet of the cooling medium channel.

As a further improvement to the hypergravity gas cycle refrigeration method of the present invention:

2.13 High-temperature and high-pressure carbon dioxide flows out from the outlet of the refrigerant channel of the rotating spiral heat exchanger, and flows adiabatically through the pipeline to the inlet of the second refrigerant channel of the dual-channel rotating tube. The pressure continues to decrease, the inertial potential energy increases, and the temperature continues to drop. When the refrigerant channel of the rotating tube 2 enters the inlet, the pressure drops to the low-pressure subcritical region, and the temperature drops to become a low-temperature and low-pressure carbon dioxide liquid; the low-temperature and low-pressure carbon dioxide liquid enters the refrigerant channel of the dual-channel rotating tube 2, and then passes through the dual-channel rotating The refrigerant channel inlet of pipe 2, the rotary joint 2, and the refrigerant channel inlet of dual-channel fixed tube 2 enter the refrigerant channel of dual-channel fixed tube 2, and then flow out from the outlet of the dual-channel fixed tube 2 refrigerant channel into the section Throttle valve, the temperature and pressure of the low-temperature and low-pressure carbon dioxide liquid passing through the throttle valve are further reduced, and become a carbon dioxide mixed liquid with a certain dryness at a lower pressure, and then the carbon dioxide mixed liquid enters the heat-absorbing channel of the heat exchanger;

2.14 After the carbon dioxide mixed liquid absorbs the heat released by the medium in the heat release channel connected to the external low-temperature heat source in the heat-absorbing channel of the heat exchanger, the dryness increases and becomes low-temperature and low-pressure carbon dioxide gas, and then enters the compressor inlet, and so on. .

As a further improvement to the hypergravity gas cycle refrigeration method of the present invention:

When the temperature of the air or carbon dioxide at the outlet of the second refrigerant channel of the dual-channel fixed tube changes, it can be adapted by adjusting the speed of the rotating spiral heat exchanger and the work of the compressor, that is, when the required temperature is lower, increase the speed and compression The machine does work, otherwise, the speed is reduced and the compressor does work;

The rotary spiral heat exchanger rotates in the vacuum protective shell. When the vacuum degree in the vacuum protective shell is not enough, start the vacuum pump, and pump out the air in the vacuum protective shell through the gas outlet of the vacuum protective shell to reach the required vacuum degree;

When the rotating spiral heat exchanger needs to increase the speed, the clutch is closed, and the accumulator outputs torque to the CVT through the internal transmission shaft, and the CVT outputs torque to the external energy storage device shaft, and the external energy storage device outputs torque to the intermediate shaft , the intermediate shaft outputs torque to the driving gear through the intermediate shaft gear, and the driving gear outputs torque to the dual-channel rotating tube 1, so that the rotating spiral heat exchanger speeds up. When the rotating speed reaches the set value, the clutch is opened, and the intermediate shaft is no longer Accept the torque of the shaft of the external energy storage device; when the rotating spiral heat exchanger needs to be decelerated, the clutch is closed, and the dual-channel rotating tube outputs torque to the driving gear, and the driving gear outputs torque to the intermediate shaft through the intermediate shaft gear, and the intermediate shaft stores energy externally The device shaft outputs torque, the external energy storage device outputs torque to the CVT, the CVT outputs torque through the internal drive shaft, and the internal drive shaft outputs torque to the accumulator, thereby storing the deceleration energy of the rotating spiral heat exchanger in the storage In the energy device, when the speed decreases to the set value, the clutch is opened, and the intermediate shaft no longer outputs torque to the external energy storage device shaft.

Compared with the traditional gas cycle refrigeration system, the high gravity gas cycle refrigeration system of the present invention has the following technical advantages:

1. The refrigerant is compressed when flowing in the centrifugal direction in the rotating spiral heat exchanger, and expands when flowing in the centripetal direction in the rotating spiral heat exchanger. There is no usual compressor and expander in the process of compression and expansion The disk loss, volume loss and dynamic-static conversion loss in the system have high compression efficiency, expansion efficiency and energy recovery efficiency.

2. The compression process of the refrigerant in the present invention is mainly completed by the centrifugal effect, and the net compression work actually required by the system cycle is greatly reduced, so the compression ratio of the required compressor is greatly reduced, and there is no need to use a reduction Regeneration measure of compression ratio.

3. When the refrigerant is centrifugally flowing in the heat exchange channel of the rotating spiral heat exchanger, it is compressed while expelling heat, so it can approximate isothermal compression and effectively reduce superheat loss.

4. The dynamic and static seals of the present invention are located in the low pressure zone (rotary joint), and there is no dynamic and static seal in the high pressure zone, so the requirements for dynamic and static seals are relatively low.

The open-type hypergravity gas cycle refrigeration method comprises the following steps (taking air as the refrigeration working medium as an example):

1.11 Use belt drive or coupling drive to make the rotary spiral heat exchanger 5, the first dual-channel rotary tube 4 and the second dual-channel rotary tube 6 maintain a certain speed of rotation, so that the refrigerant channel and the refrigerant channel of the rotary spiral heat exchanger 5 The cooling medium channel produces a supergravity effect;

1.12 The air at normal pressure and room temperature enters the compressor inlet 11 from the room through the refrigerant inlet pipeline. After being adiabatically compressed by the compressor 1, the pressure rises and the temperature increases, and then the air flows out from the compressor outlet 12 and passes through the double-channel fixed tube The refrigerant channel inlet 211 enters the refrigerant channel of the dual-channel fixed tube-2, and then enters through the dual-channel fixed tube-refrigerant channel outlet 212 through the rotary joint-3 and the dual-channel rotary tube-refrigerant channel inlet 411 The refrigerant channel of the dual-channel rotating tube-4, then enters the refrigerant channel of the rotating spiral tube heat exchanger 5 from the outlet 412 of the dual-channel rotating tube-refrigerating medium channel through the inlet 511 of the refrigerant channel, and the pressure difference Under the joint action of inertial force, the air flows spirally outward in the refrigerant channel of the rotating spiral tube heat exchanger 5, and is gradually compressed by the centrifugal force, and the air pressure rises. At the beginning, the air temperature is lower than that of the adjacent rotating spiral tube. When the temperature of the cooling medium in the cooling medium channel of the tube heat exchanger 5 is lowered, the air will absorb the heat from the cooling medium in the cooling medium channel of the adjacent spiral tube heat exchanger 5, and the air temperature will gradually increase under the action of compression and heat absorption. Increased above the temperature of the cooling medium adjacent to it, after that, the air continues to be compressed when flowing in the refrigerant channel of the rotating helical tube heat exchanger 5, but will flow to the cooling medium channel of the rotating helical tube heat exchanger 5 The cooling medium in the cooling medium releases heat, so that the air temperature during the compression process will not be overheated much. When the air reaches the outlet 512 of the refrigerant channel located at the edge of the rotating spiral tube heat exchanger 5, the pressure reaches the maximum and the temperature is slightly higher than The temperature of the cooling medium at the inlet 521 of the cooling medium channel approximately realizes isothermal compression.

1.13 The air flows out from the outlet 512 of the refrigerant channel, and flows adiabatically through the pipe to the inlet 611 of the second refrigerant channel of the dual-channel rotating tube. The pressure keeps decreasing, the inertial potential energy increases, and the temperature keeps dropping. It is an adiabatic expansion process. At the same time, the air expands During the process, when its temperature is lower than its dew point temperature, a small amount of water vapor contained in the air will be condensed, and the moisture content of the air will be slightly reduced, and the condensed water will be transported to the condensed water discharge valve 53 under the action of centrifugal force. And discharge through the condensed water discharge valve 53. When the air reaches the inlet 611 of the dual-channel rotating tube 2 refrigerant channel, the air pressure drops to normal pressure, and the temperature drops to be lower than the air in the room, becoming low-temperature air at normal pressure; the normal-pressure low-temperature air passes through the dual-channel rotating tube 2 for refrigeration. The refrigerant channel inlet 611 enters the refrigerant channel of the dual-channel rotary tube No. 2 6, and then enters through the dual-channel rotary tube No. The refrigerant channel of the dual-channel fixed tube 2 8 finally enters the refrigerant outlet pipeline from the outlet 812 of the dual-channel fixed tube 2 refrigerant channel and flows into the room.

1.14 After the normal-pressure low-temperature air sent into the room absorbs the heat of the room, the temperature increases to become normal-pressure room-temperature air, and then enters the compressor inlet 11 through the refrigerant inlet pipeline again, and so on.

1.15 The cooling medium with lower temperature under normal pressure (the cooling medium should have less compressibility and compression heat effect during the working process, such as water) enters the dual-channel fixed pipe through the second cooling medium channel inlet 821 through the external cooling medium inlet pipeline. The cooling medium channel of the channel fixed pipe 2 8, and then enters the cooling medium channel of the dual-channel rotating tube 2 6 through the outlet 822 of the dual-channel fixed pipe 2 cooling medium channel, the rotary joint 2 7 and the inlet 621 of the cooling medium channel of the dual-channel rotating tube 2 , and then flow out from the outlet 622 of the second cooling medium channel of the dual-channel rotating tube, and flow adiabatically through the pipeline to the cooling medium channel inlet 521 located at the edge of the rotating spiral heat exchanger 5, the pressure of the cooling medium increases, the temperature remains basically unchanged, and the inertial potential energy decreases .

1.16 After the cooling medium enters the cooling medium channel of the rotary spiral heat exchanger 5 from the cooling medium channel inlet 521, under the joint action of the pressure difference force and the inertial force, the cooling medium spirals in the cooling medium channel of the rotary spiral heat exchanger 5 internal flow, the pressure gradually decreases, and at the same time the cooling medium absorbs the heat of the refrigerant in the adjacent refrigerant channel in the rotating spiral tube heat exchanger 5, the temperature of the cooling medium increases, and the inertial potential energy increases. When the temperature of the working medium is higher than that, it will discharge heat to the adjacent refrigerant, and the temperature will drop. When the cooling medium flows to the cooling medium channel outlet 522 located at the axial center of the rotating spiral heat exchanger 5, the pressure of the cooling medium will return to Atmospheric pressure becomes a cooling medium with a higher temperature under normal pressure, and then the cooling medium enters the cooling medium channel of the dual-channel rotating tube-4 through the cooling medium channel outlet 522 and the dual-channel rotating tube-cooling medium channel inlet 421; The channel rotating tube-cooling medium channel outlet 422, the rotary joint-3 and the dual-channel fixed tube-cooling medium channel inlet 221 enter the cooling medium channel of the dual-channel fixed tube-4, and finally pass through the dual-channel fixed tube-cooling medium channel outlet 222 The external cooling medium outlet line flows back to the external cooling source.

1.17 The temperature of the cooling medium flowing back to the external cooling source decreases after the external cooling source releases heat, and then re-enters the second cooling medium channel inlet 821 of the dual-channel fixed pipe through the external cooling medium inlet pipeline, and circulates like this.

1.18 When the air temperature at the outlet 812 of the second refrigerant channel of the dual-channel fixed tube changes, it can be adapted by adjusting the rotation speed of the rotating spiral heat exchanger 5 and the work done by the compressor 1, that is, when the required temperature is lower, increase the rotation speed Work with compressor 1, otherwise, reduce the speed and work with compressor 1. The adjustment control index is divided into the refrigerant outlet temperature index and the refrigerant outlet pressure index. The criterion for the completion of the adjustment is: the air temperature at the outlet 812 of the second refrigerant channel of the dual-channel fixed tube is equal to the set temperature, then the refrigerant outlet The temperature index reaches the standard; the air pressure at the outlet 812 of the second refrigerant channel of the dual-channel fixed pipe is slightly greater than the refrigerant pressure at the compressor inlet 11, and the refrigerant outlet pressure index reaches the standard; The adjustment will be completed after the quality export pressure indicators are all up to standard. (the air of this step refers to refrigerant, also can refer to carbon dioxide in following embodiment)

1.19 The rotating spiral heat exchanger 5 rotates in the vacuum protection shell 9 to ensure low air friction resistance during rotation. When the vacuum degree in the vacuum protection shell 9 is not enough, start the vacuum pump 10 to draw out the vacuum through the gas outlet 91 of the vacuum protection shell The air in the protective shell 9 can reach the required vacuum degree.

1.20 When the rotational speed of the spiral heat exchanger 5 needs to be increased, the clutch 19 is closed, the accumulator 24 outputs torque to the continuously variable transmission 22 through the internal transmission shaft 23, and the continuously variable transmission 22 outputs torque to the external energy storage device shaft 20, and the external energy storage device The energy device shaft 20 outputs torque to the intermediate shaft 18, and the intermediate shaft 18 outputs torque to the driving gear 16 through the intermediate shaft gear 17, and the driving gear 16 outputs torque to the dual-channel rotating tube-4, so that the rotational speed of the rotating spiral heat exchanger 5 is accelerated. When the rotational speed increases to the set value (the set value refers to the set value of the air temperature and pressure at the outlet of the second refrigerant channel of the dual-channel fixed tube), the clutch 19 is opened, and the intermediate shaft 18 no longer accepts the external energy storage device The torque of the shaft 20 , which in the process energizes the accumulator 24 . When the rotating spiral heat exchanger 5 needs to be decelerated, the clutch 19 is closed, and the dual-channel rotating tube 14 outputs torque to the driving gear 16, and the driving gear 16 outputs torque to the intermediate shaft 18 through the intermediate shaft gear 17, and the intermediate shaft 18 stores energy to the outside The device shaft 20 outputs torque, the external energy storage device shaft 20 outputs torque to the continuously variable transmission 22, the continuously variable transmission 22 outputs torque through the internal transmission shaft 23, and the internal transmission shaft 23 outputs torque to the accumulator 24, thereby exchanging heat from the rotating spiral The deceleration energy of the device 5 is stored in the accumulator 24. When the speed decreases to the set value, the clutch 19 is opened, and the intermediate shaft 18 no longer outputs torque to the external energy storage device shaft 20. This process stores energy for the accumulator 24 .

The isobaric heat exchanger in the table is the heat exchanger used for cooling the outlet gas of the compressor in a common carbon dioxide transcritical system as a comparison. 56.737Mpa), the calculated result shows that the system COP is 5.33, instead of using the usual carbon dioxide transcritical circulation system of the rotating spiral heat exchanger 5, under the same conditions, the COP is only 0.92, and a large amount of power consumption of the compressor 1 becomes a superheat loss, A small part of the power consumption is due to throttling loss, and the temperature at the outlet 12 of the compressor is as high as 221.27°C, while the temperature at the outlet 12 of the compressor in Example 2 is only 74.25°C. The main reason is that the rotating spiral heat exchanger 5 discharges heat while compressing. The characteristics of the gas effectively control the overheating of the gas, and at the same time, the expansion process does not require the throttle valve 15, thereby reducing the throttling loss.

The thermodynamic calculation result of table 2 embodiment 2,3 and 4 (for 1kg carbon dioxide)

Embodiment 3 See Table 2 for the calculation parameters of the second closed hypergravity gas cycle refrigeration system (for the transcritical cycle of 1kg carbon dioxide), and use the cooler 14 to cool before the refrigerant medium enters the rotating spiral heat exchanger 5 , on the basis of the first type of closed hypergravity gas cycle, the superheat can be further reduced, so that the power consumption of the compressor 1 is reduced from 39.14kJ/kg to 33.13kJ/kg, and the temperature of the compressor outlet 12 is also reduced from 74.25°C is reduced to 64.29°C, and the COP of the system is increased from 5.33 to 6.3. At the same time, the exhaust heat of the rotary spiral heat exchanger 5 is also reduced from 244.3kJ/kg to 156.89kJ/kg. It can be seen that the cooler is used in Example 3 After 14, the COP of the system is effectively improved, and at the same time, the heat exchange area required by the rotating spiral heat exchanger 5 is smaller, which has an obvious improvement effect.

The calculated parameters for the third closed hypergravity gas cycle refrigeration system in Embodiment 4 are shown in Table 3 (for the transcritical cycle of 1 kg of carbon dioxide). After the throttle valve 15 is adopted, the maximum pressure of the carbon dioxide transcritical circulation system can be greatly reduced at the same evaporation temperature, such as the maximum pressure of the embodiment 4 is reduced from 56.737Mpa to 12Mpa compared with the embodiment 3, and the rotating spiral The exhaust heat of heat exchanger 5 is reduced from 244.3kJ/kg to 108.82kJ/kg, the rotating speed is reduced from 3849 rpm to 1941 rpm, and the COP of the system is reduced from 6.3 to 6.3 to 4.43, but the advantage of the loss of system efficiency is that the pressure is greatly reduced, the feasibility and safety are greatly enhanced, and the speed and heat exchange area are greatly reduced, which is conducive to the small size of the rotating spiral heat exchanger 5 change.

It can be seen that, compared with the traditional gas cycle refrigeration system, the present invention can greatly improve the refrigeration efficiency of the gas cycle system, has higher energy recovery efficiency and the characteristics of approximately isothermal compression, and avoids the use of expensive coaxial compression-expansion The machine device reduces the required power of the compressor 1, and can greatly reduce the gas temperature at the compressor outlet 12, improves the system efficiency and feasibility, and effectively achieves the purpose of the present invention.
