Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a condenser, a refrigerant purification system, and a refrigerant purification method, device, computer equipment, storage medium, and computer program product. Background Art

[0002] The chiller is the cooling source of the refrigeration equipment. When the chillers on the market are working, because the working pressure is lower than the atmospheric pressure, a low-pressure area with a lower air pressure than the atmospheric pressure will be formed inside the chiller, causing non-condensable gases such as air to enter the chiller through the low-pressure area. For example, the gaseous refrigerant layer at the top of the condenser in the chiller causes the non-condensable gas to mix with the gaseous refrigerant at the top of the condenser, forming a mixed gas in the gaseous refrigerant layer at the top of the condenser (the refrigerant inside the condenser can be divided into three layers from top to bottom: gaseous refrigerant layer, gas-liquid mixed refrigerant layer, and liquid refrigerant layer). As more and more non-condensable gases enter the condenser, the condensing capacity of the condenser will decrease, affecting the cooling effect of the refrigeration equipment.

[0003] In traditional technology, it is usually necessary to spend a lot of money to use special equipment and go through multiple process steps to separate the mixed gas in the condenser. Therefore, there is an urgent need for a device that can separate the mixed gas in the condenser at low cost and high efficiency and purify the refrigerant in the gaseous refrigerant layer of the condenser.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0083] In order to separate the mixed gas in the condenser at low cost and high efficiency and purify the refrigerant in the gaseous refrigerant layer of the condenser, the embodiment of the present application provides a condenser tank, a condenser tank structure and a condenser tank application environment, which can be specifically shown in FIG1 , wherein:

[0084] The condenser 1 comprises a condenser gas collecting port 10, a condenser pipe 11, a refrigerant return port 12 and a condenser exhaust port 13;

[0085] The gas collecting port 10 of the condenser tank is connected to the gas inlet 20 of the condenser 2, the first pipe port 111 of the condenser tube 11 is connected to the liquid inlet 21 of the condenser 2, the liquid inlet 21 is arranged at the liquid refrigerant layer of the condenser 2, the second pipe port 112 of the condenser tube 11 and the refrigerant reflux port 12 are respectively connected to the liquid refrigerant recovery unit 3, and the exhaust port 13 of the condenser tank is connected to the non-condensable gas exhaust unit 4;

[0086] The condenser gas collecting port 10 is used to collect the mixed gas in the condenser 2, and the mixed gas includes a gaseous refrigerant and a non-condensable gas;

[0087] The condenser 11 is used to condense the gaseous refrigerant in the condenser tank 1 into liquid refrigerant, so as to separate the gaseous refrigerant and the non-condensable gas in the condenser tank 1;

[0088] The refrigerant return port 12 is used to guide the liquid refrigerant deposited at the bottom of the condensation tank 1 after condensation to the liquid refrigerant recovery unit 3;

[0089] The condenser exhaust port 13 is used to discharge the separated non-condensable gas to the non-condensable gas exhaust unit 4.

[0090] Among them, the condenser 1 includes but is not limited to the shape shown in Figure 1, and can be a cuboid, a cube, a cylinder, etc. The specific shape can be designed based on factors such as installation space and maintenance convenience, so that the condenser 1 has a certain volume, and the condenser 11 can be installed through the shell of the condenser 1. The condenser gas collecting port 10, the refrigerant reflux port 12, the condenser exhaust port 13, and the first pipeline 111 and the second pipeline 112 of the condenser 11 all have good sealing properties, and can be externally piped to transmit fluids. The first pipeline 111 and the second pipeline 112 of the condenser 11 both penetrate the outer shell of the condenser 1 (without destroying the sealing property of the condenser 1) so that the condenser 11 can transmit liquid refrigerant to the outside world.

[0091] Among them, the condenser 2 is an important component in the chiller, which can be refrigerated by a refrigerant. The refrigerant is also a refrigerant, which is a substance that can be continuously circulated in the refrigeration equipment and realize refrigeration through its own state change. The refrigerant can be divided into three layers in the condenser 2, the top layer is a gaseous refrigerant layer, the middle layer is a gas-liquid mixed refrigerant layer, and the bottom layer is a liquid refrigerant layer. After the non-condensable gas enters the condenser 2, the non-condensable gas will gather in the gaseous refrigerant layer, mix with the gaseous refrigerant in the gaseous refrigerant layer, form a mixed gas, and affect the operation effect of the condenser 2. The liquid refrigerant recovery unit 3 can recover the liquid refrigerant deposited at the bottom of the condensing tank 1 through the refrigerant reflux port 12, and can also recover the liquid refrigerant in the condensing tube 11 through the second nozzle 112 of the condensing tube 11, thereby improving the utilization rate of the refrigerant. The non-condensable gas discharge unit 4 can guide the non-condensable gas separated in the condensing tank 1 through the condensing tank exhaust port 13, and discharge the non-condensable gas.

[0092] Specifically, in this embodiment, an air inlet 20 is provided at the top of the condenser 2, so that the condenser tank gas collection port 10 is connected to the gaseous refrigerant layer at the top of the condenser 2 through the air inlet 20, so that the mixed gas gathered in the gaseous refrigerant layer can flow into the condenser tank 1, so that the condenser tube 11 in the condenser tank 1 condenses and liquefies the gaseous refrigerant in the mixed gas. A liquid inlet 21 is provided on the side wall of the liquid refrigerant layer of the condenser 2, and the first tube port 111 of the condenser tube 11 is connected to the liquid inlet 21 of the condenser 2, so that the liquid refrigerant in the condenser 2 can be conveniently introduced into the condenser tube 11 as the refrigerant of the condenser tube 11, without the need to spend extra costs to introduce the refrigerant into the condenser tube 11 in the condenser tank 1. This structure for introducing the refrigerant into the condenser tube 11 is simple and effective. Furthermore, in this embodiment, the refrigerant return port 12 of the condenser tank 1 and the second pipe port 112 of the condenser tube 11 are both connected to the liquid refrigerant recovery unit 3, and the refrigerant can be recycled through the liquid refrigerant recovery unit 3, for example, the recycled refrigerant can be re-injected into the condenser 2 or used for other purposes. In this embodiment, the non-condensable gas that has not been liquefied and separated in the condenser tank 1 can also be discharged to the non-condensable gas discharge unit 4 through the condenser tank exhaust port 13 to achieve the removal of the non-condensable gas.

[0093] The condenser 1 includes a condenser gas collecting port 10, a condenser pipe 11, a refrigerant return port 12 and a condenser exhaust port 13. The condenser gas collecting port 10 is connected to the gas inlet 20 of the condenser 2, so that the condenser 1 can collect the mixed gas (including gaseous refrigerant and non-condensable gas) in the condenser 2 through the condenser gas collecting port 10. Furthermore, the first pipe port 111 of the condenser pipe 11 is connected to the liquid inlet 21 of the condenser 2, and the liquid inlet 21 is arranged at the liquid refrigerant layer of the condenser 2, so that the condenser pipe 11 can introduce the liquid refrigerant in the condenser 2 as a refrigerant, thereby condensing the gaseous refrigerant in the condenser 1 into liquid refrigerant, and separating the gaseous refrigerant and non-condensable gas in the condenser 1. The second pipe opening 111 and the refrigerant return port 12 are respectively connected to the liquid refrigerant recovery unit 3, so that the liquid refrigerant recovery unit 3 can recover the liquid refrigerant in the condenser tube 11 through the second pipe opening 112, and recover the liquid refrigerant deposited at the bottom of the condenser tank 1 after condensation through the refrigerant return port 12. Furthermore, the condenser tank exhaust port 13 is connected to the non-condensable gas discharge unit 4, so that the non-condensable gas discharge unit 4 can guide the non-condensable gas separated in the condenser tank 1 through the condenser tank exhaust port 13, and then discharge the non-condensable gas. With the above-mentioned condenser tank 1, there is no need to spend extra cost to introduce refrigerant into the condenser tube 11, and there is no need to go through multiple process steps. The mixed gas collected from the condenser 2 can be separated conveniently and efficiently through the condenser tube 11, and the liquid refrigerant in the condenser tube 11 and the condensation and liquefaction separation can also be recovered, and the separated non-condensable gas can be discharged, which can achieve low-cost and efficient separation of the mixed gas in the condenser 2 and purify the refrigerant in the gaseous refrigerant layer of the condenser 2.

[0094] In one embodiment, based on the application environment shown in FIG. 1 , as shown in FIG. 2 , the gas collecting port 10 of the condenser tank is connected to the gas inlet 20 of the condenser 2 through the first solenoid valve 5 to connect to the gaseous refrigerant layer at the top of the condenser 2 , in which a mixed gas is gathered.

[0095] Among them, the solenoid valve is an automation component that can control the on and off of the pipeline through electromagnetic force.

[0096] Exemplarily, when the first solenoid valve 5 is turned on, the mixed gas in the gaseous refrigerant layer at the top of the condenser 2 can flow out from the gas inlet 20 along the pipeline, pass through the first solenoid valve 5, flow to the condenser gas collecting port 10 of the condenser 1, and then flow into the condenser 1.

[0097] It should be noted that, in the scenario where the gas pressure in the gaseous refrigerant layer of the condenser 2 is too high, the first solenoid valve 5 can be opened to conveniently and quickly release the gas (which can be a mixed gas or only a gaseous refrigerant) in the gaseous refrigerant layer to the condenser tank 1 to achieve unloading of the condenser 2 and avoid excessive gas pressure in the gaseous refrigerant layer of the condenser 2. That is, the condenser tank 1 can have the dual functions of purifying the refrigerant in the condenser 2 and unloading the condenser 2, and both the purification function and the unloading function can be achieved by controlling the conduction of the first solenoid valve 5.

[0098] In this embodiment, the conduction of the first solenoid valve 5 can be controlled to achieve purification or unloading of the refrigerant in the gaseous refrigerant layer of the condenser 2, which is beneficial to improving the refrigeration effect of the refrigeration equipment and ensuring the operating performance and safety of the refrigeration equipment.

[0099] In a possible implementation, based on the application environment of the condenser shown in Figure 2, as shown in Figure 3, the first pipe mouth 111 of the condenser 11 can be connected to the second solenoid valve 7 through the expansion valve 6, and the second solenoid valve 7 is connected to the liquid intake port 21 of the condenser 2, or, as shown in Figure 4, the first pipe mouth 111 of the condenser 11 is connected to the expansion valve 6 through the second solenoid valve 7, and the expansion valve 6 is connected to the liquid intake port 21 of the condenser 2.

[0100] The expansion valve 6 has the functions of throttling, reducing pressure and adjusting flow rate, and can control the flow rate of liquid refrigerant (refrigerant) by changing the cross-sectional area of ​​the channel.

[0101] For example, when the second solenoid valve 7 is in the on state, the liquid refrigerant in the condenser 2 can flow out from the liquid inlet 21 of the condenser 2, through the expansion valve 6 and the second solenoid valve 7, and flow into the first pipe port 111 of the condenser 11, without the need to introduce other refrigerants into the condenser 11. When the second solenoid valve 7 is in the closed state, the liquid refrigerant in the condenser 2 will not be able to flow into the condenser 11.

[0102] In this embodiment, the expansion valve 6 and the second solenoid valve 7 can be used to control whether liquid refrigerant is injected into the condenser 11, so that the refrigerant in the condenser 2 can be reused secondary, thereby separating the mixed gas by using the condenser 11 injected with liquid refrigerant at low cost and high efficiency.

[0103] In some embodiments, as shown in FIG5 , based on the condensation tank 1 shown in FIG1 , a schematic diagram of the structure of a condensation tank including a partition is provided, wherein the condensation tank 1 further includes:

[0104] The shell 14 has a refrigerant return port 12 at the bottom thereof;

[0105] The partition 15 divides the shell 14 into a first space and a second space which are connected at the bottom, the condensing tank gas collecting port 10 is arranged at the top of the first space, and the condensing tank exhaust port 13 is arranged at the top of the second space;

[0106] The condenser 11 passes through the partition 15 and penetrates the first space and the second space; the gaseous refrigerant collected by the condenser gas collecting port 10 is condensed by the condenser 11 and deposited at the bottom of the shell 14; the non-condensable gas collected by the condenser gas collecting port 10 passes through the first space and the second space and is discharged from the condenser exhaust port 13.

[0107] The liquid refrigerant deposited on the bottom of the shell 14 may form a liquid collecting area 16 as shown in FIG. 5 .

[0108] For example, the condenser 1 shown in FIG. 5 is applied to the condenser application environment shown in FIG. 4. When the refrigerant purification instruction is received, the first solenoid valve 5 and the second solenoid valve 7 are both turned on, and the mixed gas at the top of the condenser 2 can flow through the pipeline, through the first solenoid valve 5, into the condenser gas collection port 10 of the condenser 1, and enter the area where the condenser tube 11 is located in the first space. In the process of passing through the first space, under the action of the condenser tube 11, at least a part of the gaseous refrigerant in the mixed gas is liquefied by cooling, converted into liquid refrigerant, and deposited in the liquid collection area 16 at the bottom of the condenser 1, while the non-condensable gas will not be liquefied by cooling (the state of the non-condensable gas itself is not easily affected by temperature), and the non-condensable gas and a small amount of unliquefied gaseous refrigerant can pass through the first space and the space above the liquid collection area to enter the area where the condenser tube 11 is located in the second space. Furthermore, in the process of passing through the second space, under the action of the condenser 11, the remaining small amount of gaseous refrigerant is liquefied by the cold, converted into liquid refrigerant, and deposited in the liquid collecting area 16 at the bottom of the condenser tank 1, while the non-condensable gas can continue to pass through the second space and flow to the condenser exhaust port 13 set at the top of the second space, so that the non-condensable gas discharge unit 4 can export the non-condensable gas separated in the condenser tank 1 through the condenser exhaust port 13, and then discharge the non-condensable gas, thereby realizing the purification of the refrigerant in the mixed gas (the purified refrigerant is liquid and deposited in the liquid collecting area 16 at the bottom of the condenser tank 1).

[0109] In this embodiment, the partition 15 can be used to separate the condensation tank 1 into two areas connected at the bottom, thereby increasing the flow time of the mixed gas in the condensation tank 1, increasing the condensation time of the gaseous refrigerant in the mixed gas by the condenser 11, improving the condensation effect, ensuring that the gaseous refrigerant and non-condensable gas in the mixed gas can be effectively separated, and further ensuring the effective purification of the gaseous refrigerant in the mixed gas.

[0110] In one embodiment, based on the condensation tank 1 shown in FIG. 5 , as shown in FIG. 6 , a schematic diagram of the structure of a condensation tank including a gas-liquid separation plate is provided, wherein the condensation tank 1 further includes:

[0111] The gas-liquid separation plate 17 is disposed at the top of the second space and below the exhaust port 13 of the condenser, and is used to separate the non-condensable gas from the liquid refrigerant carried in the non-condensable gas.

[0112] Among them, the gas-liquid separation plate 17 can separate the gas and liquid based on the difference in physical properties of the fluid, such as gravity, inertia, etc. The gas-liquid separation plate 17 has the following common separation principles: (1) Gravity separation principle: By setting a guide plate, the gas is subject to less resistance when flowing through the guide plate, while the liquid will be intercepted by the guide plate and accumulated on the plate wall, thereby achieving the separation of gas and liquid. (2) Inertial separation principle: The inertia difference between gas and liquid when changing flow direction is used for separation. The gas can change its flow direction while passing through the gas-liquid separation plate 17, while the liquid carried in the gas is not easy to change its flow direction due to its large inertia, and is thus separated from the gas under the action of inertia.

[0113] In this embodiment, the non-condensable gas that passes through the second space and flows to the exhaust port 13 of the condenser can be filtered through the gas-liquid separation plate 17, and the liquid refrigerant carried in the non-condensable gas can be isolated. The isolated liquid refrigerant can drip along the gas-liquid separation plate 17 and be deposited in the liquid collecting area 16 at the bottom of the condenser 1, thereby improving the purification effect of the refrigerant in the mixed gas and increasing the refrigerant purification output.

[0114] In a possible implementation, based on the condensation tank 1 shown in FIG. 6 , as shown in FIG. 7 , a schematic diagram of the structure of a condensation tank including fins is provided, wherein the condensation tank 1 further includes:

[0115] Fin 18: At least one fin 18 is disposed in each of the first space and the second space.

[0116] Among them, the fins 18 can increase the heat transfer area, exchange heat with the gas in the condensation tank 1, improve the condensation effect of the condensation tube 11, and ensure that the condensation tube 11 effectively condenses and liquefies the gaseous refrigerant flowing through the condensation tank 1.

[0117] Exemplarily, a plurality of fins 18 may be arranged in parallel in the first space and the second space respectively, and the arrangement direction of the fins 18 may be parallel to the direction of gravity, and the fins 18 may be interspersed in the condenser tube 11 to fully contact the gaseous refrigerant flowing through the first space and the second space, thereby improving the condensation and liquefaction effect of the condenser tube 11.

[0118] In this embodiment, the fins 18 provided in the first space and the second space can improve the condensation and liquefaction effect of the refrigerant in the mixed gas and increase the refrigerant purification output.

[0119] The embodiment of the present application also provides a refrigerant purification system, as shown in FIG8 , comprising the condensation tank 1 shown in FIG7 , and the condenser 2 and the liquid refrigerant recovery unit 3 in the condensation tank application environment shown in FIG4 ;

[0120] A return air port 22 is provided at the top of the condenser 2, and the return air port 22 is connected to the liquid refrigerant recovery unit 3. The liquid refrigerant recovery unit 3 is used to recover the liquid refrigerant discharged from the refrigerant return port 12 of the condensation tank 1 and the liquid refrigerant in the condensation tube 11 in the condensation tank 1, and convert the recovered liquid refrigerant into a gaseous refrigerant, so that the converted gaseous refrigerant flows back to the return air port 22 and enters the gaseous refrigerant layer of the condenser 2.

[0121] Exemplarily, the liquid refrigerant recovery unit 3 can specifically be a unit with heating and evaporation functions, which can heat and evaporate the liquid refrigerant flowing out of the second pipe port 112 of the condenser 11 and the liquid refrigerant flowing out of the refrigerant return port 12, so as to convert the recovered liquid refrigerant into gaseous refrigerant, and the gaseous refrigerant can flow back to the return air port 22 of the condenser 2 along the pipeline.

[0122] It should be noted that, as shown in Figure 8, a pipeline can also be set between the liquid refrigerant recovery unit 3 and the liquid refrigerant layer in the condenser 2. Regardless of whether the refrigerant purification is required, the liquid refrigerant recovery unit 3 can evaporate and vaporize the liquid refrigerant flowing into the liquid refrigerant layer, and inject the vaporized gaseous refrigerant into the return air port 22 of the condenser 2, thereby driving the circulation of the refrigerant in the condenser 2.

[0123] The above-mentioned refrigerant purification system includes a condenser 1, a condenser 2, and a liquid refrigerant recovery unit 3. The top of the condenser 2 is provided with a return air port 22, and the return air port 22 is connected to the liquid refrigerant recovery unit 3. The liquid refrigerant recovery unit 3 is used to recover the liquid refrigerant derived from the refrigerant return port 12 of the condenser 1 and the liquid refrigerant in the condenser tube 11 in the condenser 1, and convert the recovered liquid refrigerant into a gaseous refrigerant, so that the converted gaseous refrigerant flows back to the return air port 22 and enters the gaseous refrigerant layer of the condenser 2. By adopting the above-mentioned refrigerant purification system, there is no need to spend extra cost to introduce refrigerant into the condenser tube 11 in the condenser 1, and there is no need to go through multiple process steps. The mixed gas collected from the condenser 2 can be separated conveniently and efficiently through the condenser tube 11, and the liquid refrigerant in the condenser tube 11 and the liquid refrigerant obtained by condensation and liquefaction separation can also be recovered, which can achieve low-cost and efficient separation of the mixed gas in the condenser 2 to purify the refrigerant in the gaseous refrigerant layer of the condenser 2.

[0124] In one of the embodiments, based on the refrigerant purification system shown in FIG8 , as shown in FIG9 , the liquid refrigerant recovery unit 3 includes an evaporator 31 ;

[0125] The evaporator 31 is provided with a first liquid supply port 311 , a second liquid supply port 312 and an evaporation port 313 . The first liquid supply port 311 is connected to the refrigerant return port 12 , the second liquid supply port 312 is connected to the second tube port 112 of the condenser 11 , and the evaporation port 313 is connected to the return air port 22 .

[0126] The evaporator 31 is a device that can convert liquid substances into gaseous substances.

[0127] For example, in this embodiment, the evaporator 31 may include a heating chamber (not shown in FIG. 9 ) and an evaporation chamber (not shown in FIG. 9 ). The heating chamber may provide the heat required for evaporation to the liquid refrigerant flowing into the evaporator 31 , so as to cause the liquid refrigerant to boil and vaporize, while the evaporation chamber may completely separate the gas and liquid phases. That is, the liquid refrigerant may enter the heating chamber in the evaporator 31 through the first liquid supply port 311 , the second liquid supply port 312 , and the pipeline between the liquid refrigerant layer and the evaporation chamber, and the heating chamber is connected to the evaporation chamber, and the vaporized gaseous refrigerant may enter the evaporation chamber, flow into the pipeline from the evaporation port 313 connected to the evaporation chamber, flow to the return air port 22 , and then be injected into the gaseous refrigerant layer of the condenser 2 , so as to realize the recycling of the refrigerant.

[0128] In this embodiment, the refrigerant in the condenser 2 can be recycled through the evaporator 31 in the liquid refrigerant recovery unit 3, thereby purifying the refrigerant in the condenser 2 at a low cost.

[0129] In some embodiments, based on the refrigerant purification system shown in FIG. 9 , as shown in FIG. 10 , the liquid refrigerant recovery unit 3 may further include a compressor 32 , and the compressor 32 is disposed between the evaporation port 313 and the return air port 22 .

[0130] The compressor 32 is a device that can boost low-pressure gas to high-pressure gas. The piston in the compressor 32 can be driven by a motor to compress the gas entering the compressor 32 and then discharge the high-pressure gas.

[0131] Exemplarily, as shown in FIG10 , the evaporation port 313 can be connected to the compressor air inlet 321 of the compressor 32, and the compressor exhaust pipe 322 of the compressor 32 can be connected to the return air port 22. That is, the compressor 32 can compress the gaseous refrigerant that evaporates and flows out from the evaporation port 313 and flows into the compressor air inlet 321, and discharge the high-pressure gaseous refrigerant through the compressor exhaust pipe 322, providing power for the recycling of the refrigerant, so that the gaseous refrigerant obtained by the recovery and conversion can be smoothly injected into the return air port 22 of the condenser 2 from the compressor exhaust pipe 322 under the action of the pressure difference.

[0132] In this embodiment, the compressor 32 can provide power for the refrigerant circulation process to ensure the smooth progress of the refrigerant purification and recycling process.

[0133] In an exemplary embodiment, based on the refrigerant purification system shown in Figure 10, as shown in Figure 11, the refrigerant purification system also includes a non-condensable gas discharge unit 4, and the non-condensable gas discharge unit 4 is used to discharge the non-condensable gas discharged from the condenser exhaust port 13 of the condenser 1.

[0134] Exemplarily, the non-condensable gas discharge unit 4 can extract the gas and discharge the extracted gas to the outside, and can also have the function of temporarily storing a portion of the gas. In this embodiment, the non-condensable gas discharge unit 4 can discharge the non-condensable gas gathered at the condenser exhaust port 13 through the condenser exhaust port 13, and can also temporarily store a portion of the extracted non-condensable gas. When the discharge condition is met, the stored non-condensable gas can be discharged to the outside.

[0135] In this embodiment, the non-condensable gas separated from the mixed gas can be discharged through the non-condensable gas discharge unit 4 to avoid interference of the non-condensable gas with the operation process of the condenser 2.

[0136] In one embodiment, based on the refrigerant purification system shown in FIG. 11 , as shown in FIG. 12 , the non-condensable gas discharge unit 4 includes a gas tank 41 and an evacuation pump 42, wherein:

[0137] The gas tank 41 includes a gas tank gas collecting port 411 and a gas tank exhaust port 412 . The gas tank gas collecting port 411 is connected to the condenser exhaust port 13 of the condenser 1 through a third solenoid valve 43 , and the gas tank exhaust port 412 is connected to the evacuation pump 42 through a fourth solenoid valve 44 .

[0138] The gas tank 41 has a certain volume and can be used to store the non-condensable gas discharged from the condenser exhaust port 13. The vacuum pump 42 can evacuate the evacuated container (ie, the gas tank 41) and discharge the gas extracted from the gas tank 41 to the outside.

[0139] Exemplarily, as shown in FIG11 , the fourth solenoid valve 44 can be connected to the evacuation pump 42 through the evacuation pump air inlet 421 of the evacuation pump 42, while the evacuation pump exhaust port 422 of the evacuation pump 42 is connected to the outside. When the third solenoid valve 43 is in the conducting state, the non-condensable gas gathered at the exhaust port 13 of the condensation tank can enter the gas tank 41; when the third solenoid valve 43 is closed (not conducting), the non-condensable gas gathered at the exhaust port 13 of the condensation tank will not be able to enter the gas tank 41. If the fourth solenoid valve 44 is conducting and the evacuation pump 42 is in the working state, the evacuation pump 42 can extract the non-condensable gas stored in the gas tank 41 and discharge it to the outside; if the fourth solenoid valve 44 is closed (not conducting), the evacuation pump 42 cannot extract the non-condensable gas stored in the gas tank 41.

[0140] In this embodiment, the non-condensable gas can be discharged through the gas tank 41 and the vacuum pump 42 in the non-condensable gas discharge unit 4 to achieve the discharge of the non-condensable gas.

[0141] In one embodiment, based on the refrigerant purification system shown in FIG. 12 , as shown in FIG. 13 , the gas tank 41 further includes a pressure sensor 413 , and the pressure sensor 413 is used to detect the gas pressure in the gas tank 41 ;

[0142] When the air pressure in the air tank 41 rises to the first air pressure threshold, the third solenoid valve 43 is closed, the fourth solenoid valve 44 is turned on, and the evacuation pump 42 starts to operate;

[0143] When the air pressure in the air tank 41 drops to the second air pressure threshold, the third solenoid valve 43 is turned on, the fourth solenoid valve 44 is turned off, and the evacuation pump 42 stops running.

[0144] Among them, the first air pressure threshold is greater than the second air pressure threshold, and the first air pressure threshold and the second air pressure threshold can be flexibly configured based on the actual application scenario. The pressure sensor 413 can detect the pressure signal (such as the air pressure in the gas tank 41), and can convert the pressure signal into a usable output electrical signal according to a certain rule, so that the controller of the refrigerant purification system can control the conduction state of the third solenoid valve 43 and the fourth solenoid valve 44, and control the working state of the evacuation pump 42 based on the electrical signal fed back by the pressure sensor.

[0145] It should be noted that the gas volume of the condensation tank 1 can ensure that while waiting for the evacuation pump 42 to restart operation, the gas pressure in the condensation tank 1 will not affect the operation of the various components in the condensation tank 1. That is, in this embodiment, when designing the size of the condensation tank 1, it will be ensured that the gas volume of the condensation tank 1 is greater than the amount of gas entering the condensation tank 1 when the evacuation pump 42 stops operating.

[0146] In this embodiment, the process of discharging the non-condensable gas can be fully automatically controlled by the pressure sensor 413 , so that the non-condensable gas in the condenser 2 can be discharged efficiently and conveniently.

[0147] The embodiment of the present application also provides a refrigerant purification method, which can be applied to a refrigerant purification system as shown in FIG13. The refrigerant purification system includes a condensing tank 1, a condenser 2, a liquid refrigerant recovery unit 3, and a non-condensable gas discharge unit 4. The refrigerant purification system may also include a controller (not shown in FIG13). The controller may specifically be a main control chip (MCU) of the refrigerant purification system, which may automatically control the operation of each component in the refrigerant purification system according to the received instructions. There are multiple types of instructions received by the controller, which may be remotely triggered by a user using a terminal device, may be triggered by a user by pressing a touch screen / button, or may be triggered by a pressure sensor in the refrigerant purification system.

[0148] Specifically, when the controller receives the refrigerant purification instruction, the controller can control the mixed gas in the condenser 2 to flow from the air inlet 20 of the condenser 2 into the condenser gas collecting port 10 of the condenser 1, and control the liquid refrigerant in the condenser 2 to be injected from the liquid inlet 21 of the condenser 2 into the first pipe port 111 of the condenser tube 11 in the condenser 1, so that the condenser tube 11 condenses the gaseous refrigerant in the mixed gas in the condenser 1 into liquid refrigerant to separate the non-condensable gas in the mixed gas. At the same time, the controller can also control the liquid refrigerant recovery unit 3 to convert the liquid refrigerant recovered from the refrigerant return port 12 of the condenser 1 and the second pipe port 112 of the condenser tube 11 into gaseous refrigerant, and inject the converted gaseous refrigerant into the return air port 22 of the condenser 2, and control the non-condensable gas discharge unit 4 to discharge the non-condensable gas derived from the condenser exhaust port 13 of the condenser 1.

[0149] In one embodiment, as shown in FIG14 , a refrigerant purification method is provided, and the method is applied to the refrigerant purification system in FIG13 as an example for description, including the following steps:

[0150] Step 1402, when receiving the refrigerant purification instruction, control the mixed gas in the condenser to flow from the gas inlet of the condenser into the condenser gas collecting port of the condenser tank, and control the liquid refrigerant in the condenser to be injected from the liquid inlet of the condenser into the first pipe port of the condenser tube in the condenser tank, so that the condenser tube condenses the gaseous refrigerant in the mixed gas in the condenser tank into liquid refrigerant to separate the non-condensable gas in the mixed gas.

[0151] Optionally, when the controller receives a refrigerant purification instruction, the controller can control the first solenoid valve 5 between the air inlet 20 of the condenser 2 and the condenser gas collecting port 10 of the condenser 1 to be turned on, so that the mixed gas in the condenser 2 flows from the air inlet 20 of the condenser 2 into the condenser gas collecting port 10 of the condenser 1. At the same time, the controller can also control the second solenoid valve 7 between the liquid inlet 21 of the condenser 2 and the first pipe port 111 of the condenser tube 11 to be turned on, so that the liquid refrigerant in the condenser 2 can flow out from the liquid inlet 21, pass through the expansion valve 6 and the second solenoid valve 7, and be injected into the first pipe port 111 of the condenser tube 11 in the condenser 1. Based on this, the refrigerant is injected into the condenser tube 11, so that the condenser tube 11 can refrigerate, condense the gaseous refrigerant in the mixed gas collected in the condenser tank 1 into liquid refrigerant, and separate the non-condensable gas in the mixed gas.

[0152] Step 1404, controlling the liquid refrigerant recovery unit, converting the liquid refrigerant recovered from the refrigerant return port of the condenser tank and the second pipe port of the condenser tube into gaseous refrigerant, and injecting the converted gaseous refrigerant into the return air port of the condenser.

[0153] Optionally, when the controller receives a refrigerant purification instruction, the controller can synchronously control the liquid refrigerant recovery unit 3 to convert the liquid refrigerant recovered from the refrigerant return port 12 of the condenser tank 1 and the second pipe port 112 of the condenser tube 11 into a gaseous refrigerant, and inject the converted gaseous refrigerant into the return air port 22 of the condenser 2. It should be noted that for the liquid refrigerant flowing into the liquid refrigerant recovery unit 3 from the pipeline between the liquid refrigerant layer and the liquid refrigerant recovery unit 3, the liquid refrigerant recovery unit 3 can also be evaporated and injected into the return air port 22 of the condenser 2 when it is running.

[0154] Step 1406, controlling the non-condensable gas exhaust unit to exhaust the non-condensable gas guided out from the condenser exhaust port of the condenser.

[0155] Optionally, when the controller receives a refrigerant purification instruction, the controller can control the non-condensable gas exhaust unit 4 to start running, so as to discharge the non-condensable gas discharged from the condenser exhaust port 13 of the condenser 1 through the non-condensable gas exhaust unit 4.

[0156] The above-mentioned refrigerant purification method can control the mixed gas in the condenser 2 to flow from the gas inlet 22 of the condenser 2 into the condenser gas collecting port 10 of the condenser 1 when the controller receives the refrigerant purification instruction, and control the liquid refrigerant in the condenser 2 to be injected from the liquid inlet 21 of the condenser 2 into the first pipe port 111 of the condenser 1 in the condenser 1 without incurring additional costs to introduce refrigerant into the condenser 11, so that the condenser 11 can condense the gaseous refrigerant in the mixed gas in the condenser 1 into liquid refrigerant to separate the non-condensable gas in the mixed gas. Furthermore, the liquid refrigerant recovery unit 3 can be controlled to convert the liquid refrigerant recovered from the refrigerant return port 12 of the condenser 1 and the second pipe port 112 of the condenser tube 11 into a gaseous refrigerant, and the converted gaseous refrigerant is injected into the return port 22 of the condenser 2 to realize the recycling of the condensed liquid refrigerant and the liquid refrigerant in the condenser tube 11. The non-condensable gas discharge unit 3 can also be controlled to discharge the non-condensable gas derived from the condenser exhaust port 13 of the condenser 1. By adopting the above-mentioned refrigerant purification method, there is no need to introduce refrigerant into the condenser tube 11 at an additional cost, and there is no need to go through multiple process steps. The mixed gas collected from the condenser 2 can be separated conveniently and efficiently through the condenser tube 11. The liquid refrigerant in the condenser tube 11 and the liquid refrigerant obtained by condensation and liquefaction separation can also be recovered, and the separated non-condensable gas can be discharged, which can realize low-cost and efficient separation of the mixed gas in the condenser 2 to purify the refrigerant in the gaseous refrigerant layer of the condenser 2.

[0157] In one embodiment, taking the application of the refrigerant purification method to the refrigerant purification system shown in FIG. 13 as an example, the liquid refrigerant recovery unit 3 includes an evaporator 31 and a compressor 32 .

[0158] When the controller receives the refrigerant purification control instruction, the controller can control the evaporator 31 and the compressor 32 in the liquid refrigerant recovery unit 3 to start running, so that the evaporator 31 can convert the liquid refrigerant recovered from the refrigerant return port 12 and the second pipe port 112 of the condensation tank 1, and the liquid refrigerant flowing into the pipeline between the liquid refrigerant layer and the evaporator 31 into gaseous refrigerant, and the compressor 32 can compress the converted gaseous refrigerant and inject the compressed gaseous refrigerant into the return air port 22 of the condenser 2.

[0159] In this embodiment, the refrigerant in the condenser 2 can be recycled by controlling the operation of the liquid refrigerant recovery unit 3 .

[0160] In one of the embodiments, taking the application of the refrigerant purification method to the refrigerant purification system shown in FIG. 13 as an example, the non-condensable gas discharge unit 4 includes a gas tank 41 and an evacuation pump 42 .

[0161] When the controller receives the refrigerant purification control instruction, the controller can monitor the pressure in the gas tank 41 based on the pressure sensor 413 provided in the gas tank 41. If the gas pressure in the gas tank 41 does not reach the first gas pressure threshold, the controller can control the third solenoid valve 43 to be turned on, and the fourth solenoid valve 44 to be turned off, and the evacuation pump 42 to not operate, so that the non-condensable gas separated from the condensation tank 1 is guided out from the condensation tank exhaust port 13 of the condensation tank 1 to the gas tank 41. If the air pressure in the gas tank 41 reaches the first air pressure threshold, the controller can control the third solenoid valve 43 to close, and the fourth solenoid valve 44 to turn on, and the evacuation pump 42 to run, so as to stop the non-condensable gas from being discharged to the gas tank 41, and control the evacuation pump 42 to discharge the non-condensable gas in the gas tank 41 until the air pressure in the gas tank 41 drops to the second air pressure threshold, and then control the third solenoid valve 43 to turn on, and the fourth solenoid valve 44 to close, and the evacuation pump 42 does not run, so as to stop the non-condensable gas in the gas tank 41 from being discharged, and control the non-condensable gas separated from the condensation tank 1 to be discharged from the condensation tank exhaust port 13 to the gas tank 41.

[0162] In this embodiment, the process of removing the non-condensable gas can be automatically and flexibly controlled according to the pressure in the gas tank 41, which can simply and effectively improve the operation effect of the condenser 2.

[0163] In a specific embodiment, as shown in FIG15 , a schematic flow chart of a refrigerant purification method using the refrigerant purification system shown in FIG13 is provided, which mainly includes the following steps:

[0164] Step 1502, receiving a refrigerant purification instruction;

[0165] Step 1504, controlling the first solenoid valve and the second solenoid valve to be turned on, controlling the evaporator and the compressor to start running, and monitoring the gas pressure in the gas tank through the pressure sensor;

[0166] If the air pressure in the gas tank does not reach the first air pressure threshold, execute step 1506, control the third solenoid valve to be turned on, control the fourth solenoid valve to be turned off, and control the evacuation pump not to operate, so that the air pressure in the gas tank increases; during the execution of step 1506, monitor in real time whether the air pressure in the gas tank rises to the first air pressure threshold;

[0167] If the air pressure in the gas tank does not reach the first air pressure threshold, execute step 1508, control the third solenoid valve to close, control the fourth solenoid valve to open, and control the vacuum pump to start running to reduce the air pressure in the gas tank; in the process of executing step 1508, monitor in real time whether the air pressure in the gas tank drops to the second air pressure threshold; if the air pressure in the gas tank drops to the second air pressure threshold, return to step 1506 to increase the air pressure in the gas tank; if the air pressure in the gas tank does not drop to the second air pressure threshold, continue to execute step 1508.

[0168] In this embodiment, the refrigerant purification system shown in FIG13 can work in a cycle according to the control process shown in FIG15, so as to effectively discharge the non-condensable gas continuously from the refrigeration equipment, ensure the heat exchange efficiency of the refrigeration equipment, and improve the operating performance of the refrigeration equipment. It should be noted that the refrigerant purification process is generally set within a working time period. After receiving the refrigerant purification instruction, the controller can control the refrigerant purification process and the non-condensable gas discharge process to be cyclically carried out within this working time period. When not in the working time period of refrigerant purification, the controller can control the first solenoid valve 5, the second solenoid valve 7, the third solenoid valve 43, and the fourth solenoid valve 44 to be closed, and control the evacuation pump 422 to stop running, and can only control the evaporator 31 and the compressor 32 to operate, so as to realize the recycling of the refrigerant, that is, control the evaporator 31 to heat and evaporate the liquid refrigerant flowing into the evaporator 31 from the liquid refrigerant layer, and then inject the vaporized high-pressure gaseous refrigerant into the gaseous refrigerant layer of the condenser 2 through the compressor 32, so as to realize the recycling of the refrigerant in the condenser 2.

[0169] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
