Abstract

The application provides a marine anti-rolling refrigeration system and a control method. The system comprises a compressor, a shell-and-tube condenser, a throttling device and a liquid accumulator connected in sequence. The shell-and-tube condenser has a first outlet, and the throttling device is located downstream of the shell-and-tube condenser. The liquid accumulator comprises a containing cavity and a pressing plate. A first working medium inlet and a first working medium outlet are formed in the bottom wall or the side wall of the containing cavity. The first working medium inlet is in communication with the first outlet. The first working medium outlet is in communication with the inlet of the throttling device. The pressing plate is horizontally arranged in the containing cavity and is movably arranged on the pressing plate. The first working medium inlet and the first working medium outlet are both located below the pressing plate. When the ship body experiences relatively severe rolling, the pressing plate is pressed down to ensure that only liquid working medium can enter the first working medium outlet and then enter the throttling device, thereby avoiding the problem that gaseous refrigerant enters the throttling device due to the rolling of the ship body and avoiding the influence of the rolling of the ship body on the refrigeration capacity of the air conditioner.

Description

Technical Field

[0001] This invention relates to the field of marine air conditioning technology, and in particular to a marine anti-turbulence refrigeration system and control method. Background Technology

[0002] Marine air conditioning systems are used for overall ship temperature regulation and equipment cooling. The shell-and-tube condenser is one of the core components of a marine air conditioning system and is the most critical device for releasing the unit's heat load. The operating status of the shell-and-tube condenser directly affects the normal operation of the air conditioning system. When ships are exposed to strong winds or large waves, the marine air conditioning system is constantly in a rolling environment. Due to the long shell-and-tube condenser, when the ship rolls, the liquid refrigerant inside the condenser will slosh around. When the sloshing amplitude is large or due to inertia, the refrigerant outlet, which was originally in contact with the liquid refrigerant, will come into contact with the gaseous refrigerant due to the fluctuation of the liquid level. This causes the gaseous refrigerant to enter the throttling device downstream of the shell-and-tube condenser, reducing the cooling capacity of the refrigeration cycle and affecting the air conditioning's cooling capacity. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide a marine anti-turbulence refrigeration system and control method that overcomes or at least partially solves the above problems. It can solve the problem that gaseous refrigerant enters the throttling device due to hull turbulence, so that even if the hull is turbulent, gaseous refrigerant cannot enter the throttling device, thus avoiding the impact of hull turbulence on the cooling capacity of the air conditioner.

[0004] Specifically, the present invention provides a marine anti-turbulence refrigeration system, comprising a compressor, a shell-and-tube condenser, and a throttling device connected in sequence, wherein the shell-and-tube condenser has a first outlet; and further comprising a liquid receiver; the liquid receiver comprising:

[0005] The cavity has a first working fluid inlet and a first working fluid outlet; the first working fluid inlet is connected to the first working fluid outlet; the first working fluid outlet is connected to the inlet of the throttling device.

[0006] A pressure plate is horizontally disposed within the receiving cavity to divide the receiving cavity into an upper receiving cavity and a lower receiving cavity. The pressure plate is movably disposed vertically. The first working medium inlet and the first working medium outlet are both located below the pressure plate.

[0007] Optionally, the pressure plate is provided with micropores, the lower cavity is a liquid working fluid storage cavity, and the upper cavity is a gaseous working fluid storage cavity;

[0008] The gaseous working fluid storage chamber has a second working fluid outlet on its peripheral wall, and the second working fluid outlet is connected to the inlet of the shell and tube condenser or the inlet of the compressor.

[0009] Optionally, the shell-and-tube condenser further has a second outlet, which is located above the first outlet;

[0010] A second working fluid inlet is also provided on the peripheral wall of the gaseous working fluid storage cavity, and the second outlet is connected to the second working fluid inlet;

[0011] The marine anti-turbulence refrigeration system also includes an opening and closing device; the opening and closing device is configured to control one of the first outlet and the second outlet to operate selectively.

[0012] Optionally, the lower part of the peripheral wall of the receiving cavity is provided with a plurality of annular grooves.

[0013] Optionally, the opening and closing device includes a first switching valve and a second switching valve;

[0014] The first switching valve is configured to control the opening and closing of the first outlet;

[0015] The second switching valve is configured to control the opening and closing of the second outlet.

[0016] Optionally, the reservoir further includes:

[0017] A drive device, wherein the drive device is disposed on the liquid reservoir;

[0018] The transmission device, through which the drive device drives the pressure plate to move up and down;

[0019] Optionally, the driving device is a motor;

[0020] The transmission device includes meshing gears and racks.

[0021] This invention provides a control method for a marine anti-turbulence refrigeration system, wherein the marine anti-turbulence refrigeration system is any one of the marine anti-turbulence refrigeration systems described above.

[0022] The control method includes:

[0023] The tilt angle of the reservoir, the rotational speed of the compressor, and the pressure in the upper receiving chamber are obtained.

[0024] The motion state of the pressure plate is determined based on the tilt angle of the liquid reservoir and / or the rotational speed of the compressor and / or the pressure of the upper receiving chamber.

[0025] Optionally, determining the motion state of the pressure plate based on the tilt angle of the liquid reservoir and / or the rotational speed of the compressor and / or the pressure of the upper receiving chamber includes:

[0026] When the tilt angle of the liquid reservoir is greater than the first preset angle value and / or the rotation speed of the compressor is greater than the preset rotation speed, the pressure plate moves downward from the initial position at the first speed;

[0027] During the downward movement of the pressure plate, when the pressure in the upper receiving cavity reaches a preset pressure value, the pressure plate stops moving;

[0028] After a preset time period, the tilt angle of the liquid reservoir and the rotational speed of the compressor are obtained again.

[0029] When the tilt angle of the liquid reservoir is less than or equal to the first preset angle value and / or the rotation speed of the compressor is less than or equal to the preset rotation speed, the pressure plate moves upward to the initial position at a second speed;

[0030] The second speed is less than the first speed.

[0031] Optionally, the control method for the marine anti-turbulence refrigeration system further includes:

[0032] When the tilt angle of the reservoir is greater than the second preset angle value, the first outlet is closed;

[0033] When the tilt angle of the reservoir is less than or equal to the second preset angle value, the first outlet is opened.

[0034] In the marine anti-turbulence refrigeration system and control method of the present invention, a liquid receiver is disposed between a shell-and-tube condenser and a throttling device. The liquid working fluid flows out through the first outlet of the shell-and-tube condenser, then enters the receiving cavity through the first working fluid inlet, and finally flows out through the first working fluid outlet into the inlet of the throttling device. When the ship experiences severe turbulence, the shell-and-tube condenser will sway significantly from side to side, especially vertical shell-and-tube condensers, causing significant lateral fluctuations in the liquid level of the liquid working fluid within the condenser. This may cause the first outlet, originally connected to the liquid working fluid, to connect with the gaseous working fluid, resulting in some gaseous working fluid flowing out through the first outlet. By providing a liquid receiver, when the possibility of some gaseous working fluid flowing out through the first outlet increases during severe turbulence, the pressure plate can move up and down. Since the first working fluid inlet is located below the pressure plate, the downward movement of the pressure plate has a downward pressing effect, which can limit the lateral fluctuations of the liquid working fluid within the liquid receiver. When the receiver contains some gaseous refrigerant, it sits above the liquid refrigerant. The downward movement of the pressure plate compresses the gaseous refrigerant, which then exerts force on the liquid refrigerant, ensuring smooth surface fluctuations and preventing gaseous refrigerant from entering the first refrigerant outlet. When the receiver contains only liquid refrigerant, the downward movement of the pressure plate directly applies force to the liquid refrigerant, again ensuring smooth surface fluctuations and preventing gaseous refrigerant from entering the first refrigerant outlet. In short, by installing the receiver, when the ship experiences severe rocking, the pressure plate depresses, ensuring that only liquid refrigerant can enter the first refrigerant outlet and then the throttling device. This prevents gaseous refrigerant from entering the throttling device due to ship rocking, thus preventing the refrigerant from affecting the air conditioning's cooling capacity.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] Figure 1 This is a schematic diagram according to an embodiment of the present invention. Figure 1 As shown, and with reference Figure 2 This invention provides a marine anti-turbulence refrigeration system, comprising a compressor, a shell-and-tube condenser, a throttling device, and a liquid receiver 30 connected in sequence. The shell-and-tube condenser has a first outlet, and the throttling device is located downstream of the shell-and-tube condenser. The liquid receiver 30 includes a receiving cavity and a pressure plate 33. A first working fluid inlet 36 and a first working fluid outlet 39 are provided on the bottom or side wall of the receiving cavity. The first working fluid inlet 36 communicates with the first outlet. The first working fluid outlet 39 communicates with the inlet of the throttling device. The pressure plate 33 is horizontally disposed within the receiving cavity to divide the receiving cavity into an upper receiving cavity and a lower receiving cavity. The pressure plate 33 is movably disposed vertically. Both the first working fluid inlet 36 and the first working fluid outlet 39 are located below the pressure plate 33.

[0045] In these embodiments, the marine anti-turbulence refrigeration system includes a compressor 10, a shell-and-tube condenser 20, a liquid receiver 30, a throttling device 40, and an evaporator 50 arranged sequentially. The liquid receiver 30 is located between the shell-and-tube condenser 20 and the throttling device 40. The liquid working fluid flows out through the first outlet of the shell-and-tube condenser 20, then enters the receiving cavity through the first working fluid inlet 36, and finally flows out through the first working fluid outlet 39 into the inlet of the throttling device 40. When the ship experiences severe turbulence, the shell-and-tube condenser 20 will sway significantly from side to side, especially the vertical shell-and-tube condenser 20, causing significant lateral fluctuations in the liquid level of the liquid working fluid within the shell-and-tube condenser 20. This may cause the first outlet, which is originally connected to the liquid working fluid, to connect with the gaseous working fluid, resulting in some of the gaseous working fluid flowing out through the first outlet. By configuring the reservoir 30, when the ship experiences severe rocking, increasing the likelihood of some gaseous working fluid flowing out through the first outlet, the pressure plate 33 can move vertically. Since the first working fluid inlet 36 is located below the pressure plate 33, the downward movement of the pressure plate 33 has a downward pressure effect, which can limit the lateral fluctuation of the liquid working fluid within the reservoir 30. When there is some gaseous working fluid in the reservoir 30, the gaseous working fluid is above the liquid working fluid. The downward movement of the pressure plate 33 first compresses the gaseous working fluid, and the gaseous working fluid exerts force on the liquid working fluid, ensuring that the liquid surface fluctuation is smooth and preventing gaseous working fluid from entering the first working fluid outlet 39. When there is only liquid working fluid in the reservoir 30, the downward movement of the pressure plate 33 directly exerts force on the liquid working fluid, ensuring that the liquid surface fluctuation is smooth and preventing gaseous working fluid from entering the first working fluid outlet 39. In summary, by setting up the liquid receiver 30, when the ship experiences severe turbulence, the pressure plate 33 is pressed down to ensure that only liquid working fluid can enter the first working fluid outlet 39 and then enter the throttling device 40. This avoids the problem of gaseous refrigerant entering the throttling device 40 due to turbulence, thus preventing gaseous refrigerant from entering the throttling device 40 even when the ship is turbulent, and avoiding the impact of turbulence on the air conditioning's cooling capacity.

[0046] In some embodiments of the present invention, such as Figure 1 As shown, the pressure plate 33 is provided with micropores 331, the lower cavity is a liquid working fluid storage cavity, and the upper cavity is a gaseous working fluid storage cavity. A second working fluid outlet 38 is provided on the peripheral wall of the gaseous working fluid storage cavity 31, and the second working fluid outlet 38 is connected to the inlet of the compressor.

[0047] In these embodiments, the micropores 331 connect the lower liquid working fluid storage chamber 32 and the upper gaseous working fluid storage chamber 31. When some gaseous working fluid enters the first working fluid outlet 39, the gaseous working fluid passes through the micropores 331 into the gaseous working fluid storage chamber 31, while the liquid working fluid remains in the liquid working fluid storage chamber 32. The gaseous working fluid then enters the condenser through the second working fluid outlet 38.

[0048] In other embodiments of the present invention, the second working fluid outlet 38 is connected to the inlet of the compressor 10. The gaseous working fluid enters the compressor through the second working fluid outlet 38, serving as a gas replenishment function.

[0049] In some embodiments of the present invention, such as Figure 2 As shown, the shell-and-tube condenser 20 also has a second outlet, which is located above the first outlet. A second working fluid inlet 37 is also provided on the peripheral wall of the gaseous working fluid storage chamber 31, and the second outlet communicates with the second working fluid inlet 37. The marine anti-turbulence refrigeration system also includes an opening and closing device. The opening and closing device is configured to control the selective operation of either the first outlet or the second outlet.

[0050] In these embodiments, one of the first outlet and the second outlet operates. When the ship experiences moderate turbulence, the lateral fluctuation of the liquid working fluid is small, and the first outlet on the lower side opens, allowing the working fluid to flow out through the first outlet and enter the liquid working fluid storage chamber. When the ship experiences significant turbulence, the lateral fluctuation of the liquid working fluid is larger, and the second outlet on the upper side opens, allowing the working fluid to flow out through the second outlet and enter the gaseous working fluid storage chamber on the upper side. Then, the liquid working fluid flows downward through the micropores 331 into the liquid working fluid storage chamber. The liquid working fluid flowing in from top to bottom can suppress the fluctuation of the liquid working fluid surface in the liquid working fluid storage chamber.

[0051] In some embodiments of the present invention, a plurality of annular grooves are provided on the lower part of the peripheral wall of the receiving cavity. In some embodiments, the plurality of annular grooves are provided on the peripheral wall of the liquid working medium storage cavity, and the plurality of annular grooves are parallel to each other and spaced apart. The plurality of annular grooves can eliminate or reduce the fluctuation of the liquid working medium surface in the liquid working medium storage cavity, and also ensure that only the liquid working medium flows out of the first working medium outlet 39.

[0052] In some embodiments of the present invention, the liquid reservoir 30 further includes a drive device and a transmission device. The drive device is disposed on the liquid reservoir 30. The drive device drives the pressure plate 33 to move up and down via the transmission device.

[0053] Furthermore, in some embodiments of the present invention, the driving device is an electric motor. The transmission device includes a gear 34 and a rack 35 that mesh with each other. The motor is mounted on the reservoir 30, the rack 35 is connected to the pressure plate 33, and the gear 34 is connected to the output shaft of the motor. The gear 34 rotates as the output shaft of the motor rotates, and the rotation of the gear 34 drives the pressure plate 33 to move up and down with the rack 35. Of course, the motor and the gear 34 can also be mounted on the pressure plate 33, and the rack 35 can be mounted on the reservoir 30.

[0054] This invention also provides a control method for a marine anti-turbulence refrigeration system, wherein the marine anti-turbulence refrigeration system is any of the marine anti-turbulence refrigeration systems described above.

[0055] In some embodiments of the present invention, such as Figure 3 As shown, the control methods include:

[0056] S10: Obtain the tilt angle of the reservoir 30, the speed of the compressor, and the pressure of the lower receiving chamber;

[0057] S20: Determine the motion state of the pressure plate 33 based on the tilt angle of the liquid reservoir 30.

[0058] In these embodiments, the lower receiving cavity is a liquid working fluid storage cavity 32. When the tilt angle of the liquid receiver 30 reaches a certain angle, the pressure plate 33 moves to suppress fluctuations of the liquid working fluid in the liquid working fluid storage cavity 32. This avoids the problem of gaseous refrigerant entering the throttling device 40 due to ship turbulence, ensuring that even if the ship turbulence occurs, gaseous refrigerant cannot enter the throttling device 40, thus preventing the ship turbulence from affecting the cooling capacity of the air conditioner. Of course, when the tilt angle of the liquid receiver 30 decreases, the pressure plate 33 can also change from moving downwards to moving upwards.

[0059] In other embodiments of the present invention, the rotational speed of the compressor is obtained, and the motion state of the pressure plate 33 is determined based on the rotational speed of the compressor.

[0060] The higher the compressor speed and the faster it rotates, the stronger the compressor's ability to transport the working fluid. The faster the liquid working fluid in the receiver 30 is drawn away, the faster it is drawn away. The movement of the pressure plate 33 can also adjust the pressure of the liquid working fluid storage chamber 32 and the gaseous working fluid storage chamber 31 located on the upper side. This prevents the pressure in the liquid working fluid storage chamber 32 from being too low due to the rapid drawing away of the liquid working fluid, which would cause the gaseous working fluid in the gaseous working fluid storage chamber 31 to be sucked into the liquid working fluid storage chamber 32.

[0061] In other embodiments of the present invention, the pressure of the lower receiving cavity is obtained, and the motion state of the pressure plate 33 is determined based on the pressure of the liquid working fluid storage cavity 32.

[0062] When the pressure plate 33 moves downward to a certain position, the pressure in the liquid working medium storage chamber 32 will increase due to the decrease in volume. When the pressure in the liquid working medium storage chamber 32 reaches a certain pressure, the pressure plate 33 stops moving.

[0063] Of course, in other embodiments of the present invention, by obtaining the tilt angle of the liquid reservoir 30, the rotational speed of the compressor, and the pressure of the lower receiving chamber, the motion state of the pressure plate 33 can be determined based on the tilt angle of the liquid reservoir 30, the rotational speed of the compressor, and the pressure of the liquid working fluid storage chamber 32.

[0064] Of course, in other embodiments of the present invention, the tilt angle of the liquid reservoir 30, the rotational speed of the compressor, and the pressure of the lower receiving chamber can be obtained, and the motion state of the pressure plate 33 can be determined based on the tilt angle of the liquid reservoir 30 or the rotational speed of the compressor and the pressure of the liquid working fluid storage chamber 32.

[0065] In some embodiments of the present invention, the motion state of the pressure plate 33 is determined based on the tilt angle of the reservoir 30 and / or the rotational speed of the compressor and / or the pressure in the lower receiving chamber, including:

[0066] When the tilt angle of the liquid reservoir 30 is greater than the first preset angle value or the speed of the compressor is greater than the preset speed, the pressure plate 33 moves downward at the first speed.

[0067] During the downward movement of the pressure plate 33, when the pressure in the lower receiving cavity reaches the preset pressure value, the pressure plate 33 stops moving;

[0068] After a preset time period, the tilt angle of the reservoir 30 and the speed of the compressor are obtained again.

[0069] When the tilt angle of the liquid reservoir 30 is less than or equal to the first preset angle value and / or the speed of the compressor is less than or equal to the preset speed, the pressure plate 33 moves upward at the second speed.

[0070] The second speed is less than the first speed.

[0071] When the tilt angle of the liquid receiver 30 is greater than the first preset angle value or the compressor speed is greater than the preset speed, the pressure plate 33 moves downward rapidly. This rapid movement helps to quickly suppress fluctuations in the liquid level within the receiver and also helps to reduce the pressure in the gaseous working fluid storage chamber 31, facilitating the separation of the gaseous and liquid working fluids and reducing the amount of gaseous working fluid entering the throttling device 40, thus benefiting the refrigeration system. The pressure plate 33 can be in its initial position or any other moving position. When the pressure in the liquid working fluid storage chamber 32 reaches the preset pressure value, the pressure plate 33 stops moving. After a preset time period, the tilt angle of the liquid receiver 30 or the compressor speed is measured again. If the tilt angle of the liquid receiver 30 is less than or equal to the first preset angle value and / or the compressor speed is less than or equal to the preset speed, the likelihood of the gaseous working fluid flowing into the throttling device 40 from the second working fluid outlet 38 is reduced, and the pressure plate 33 can slowly move upward back to its initial position at a lower speed.

[0072] In some embodiments of the present invention, the control method of the marine anti-turbulence refrigeration system further includes: when the tilt angle of the liquid reservoir 30 is greater than a second preset angle value, opening the second outlet and closing the first outlet; when the tilt angle of the liquid reservoir 30 is less than or equal to the second preset angle value, closing the second outlet and opening the first outlet.

[0073] In other words, when the tilt angle of the reservoir 30 is large, the second outlet on the upper side opens, and the working fluid flows out through the second outlet and enters the gaseous working fluid storage chamber on the upper side. Then, the liquid working fluid flows downward through the micropores 331 into the liquid working fluid storage chamber. The liquid working fluid flowing down from top to bottom can suppress the fluctuations of the liquid working fluid surface in the liquid working fluid storage chamber. When the tilt angle of the reservoir 30 is not large, the first outlet on the lower side opens, and the working fluid flows out through the first outlet and enters the liquid working fluid storage chamber. The second preset angle value here can be equal to or different from the first preset angle value.

[0074] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
