Description

Technical Field

[0001] One or more embodiments of the present specification relate to the technical field of air-conditioning equipment, and in particular to a composite cold source chiller refrigeration equipment. Background Art

[0002] Air conditioning systems are essential for regulating spatial temperature, providing significant benefits for specialized processing, medical treatment, and daily life. As the core refrigeration equipment in central air conditioning systems, the performance of chillers directly impacts the overall system's operating efficiency. Hybrid chillers significantly improve system energy efficiency by integrating multiple cooling methods and intelligently switching cooling sources under varying operating conditions.

[0003] The Chinese invention patent with publication number CN119309265A provides a shell assembly and a chiller for a chiller. Through the improvement of the shell, in the chiller, the shell itself, as a cold water container, can only provide a basic cold water storage function. After the shell is partitioned by partitions, it can provide a cooling and heat exchange space. In conjunction with the dispersion of clean water by the water distribution pipe and the entry of external cooling medium, during the circulation of clean water in the shell, the structural improvement can be used to efficiently cool the clean water.

[0004] However, the applicant has found that the prior art has at least the following problems:

[0005] Since the wind force provided by the axial flow fan is not uniform across its action surface, the wind force in multiple air cavities varies greatly. This, on the one hand, leads to uneven cooling of the cold water. On the other hand, it causes large differences in the workload of each water distribution component, a high rate of component damage, and ultimately a deterioration in the cooling effect of the air-conditioning system. Summary of the Invention

DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the present disclosure is further described in detail below with reference to specific embodiments.

When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0030] One or more embodiments of this specification provide a composite cold source chiller refrigeration device, such as Figures 1 to 7 As shown, it includes a shell, a water storage chamber 101, an air cooling chamber 102 and a transfer chamber 103 are provided inside the shell, the transfer chamber 103 is provided above the water storage chamber 101, and air cooling chambers 102 are provided on both sides of the transfer chamber 103, a connecting pipe 202 is connected between the transfer chamber 103 and the water storage chamber 101, for introducing cold water in the water storage chamber 101 into the transfer chamber 103, an air inlet 104 is provided at the top of the air cooling chamber 102, and an axial flow fan 105 is provided on the air inlet 104; a partition 106 is provided between the air cooling chamber 102 and the water storage chamber 101, and multiple groups of air cooling components 301 are installed on the partition 106, each group of air cooling components 301 is arranged in a circular ring and nested in sequence from the inside to the outside, and the axis of the circular ring is on the axis of the rotating shaft of the axial flow fan 105;

[0031] The air cooling assembly 301 includes a plurality of telescopic air cylinders 302, which are arranged in a circular array around the axis of the rotation axis of the axial flow fan 105. A spiral water pipe 309 is installed inside the telescopic air cylinder 302 for returning water in the transfer chamber 103 to the water storage chamber 101. A spiral air pipe 310 is also installed inside the telescopic air cylinder 302. The spiral air pipe 310 draws air from the bottom of the telescopic air cylinder 302 upward and eventually discharges it to the outside of the housing.

[0032] A height sensor is provided at the bottom of the telescopic air cylinder 302, which is used to monitor the bottom height of multiple telescopic air cylinders 302 in the same air-cooled component 301. When the ratio of the number of telescopic air cylinders 302 with the same bottom height in the same air-cooled component 301 to the total number of telescopic air cylinders 302 is less than the proportional threshold, an alarm signal is sent, otherwise no alarm signal is sent.

[0033] During operation, the water in the water storage chamber 101 is introduced into the transfer chamber 103, and the transfer chamber 103 diverts the water to each spiral water pipe 309. By setting the air-cooling component 301 to multiple telescopic air cylinders 302, and the multiple telescopic air cylinders 302 are distributed in a circular array with the axis of the rotating shaft of the axial flow fan 105 as the axis, the air intake volume of the multiple telescopic air cylinders 302 on each air-cooling component 301 remains highly similar, and the spiral water pipes 309 in the same air-cooling component 301 are more evenly affected by the wind, thereby greatly improving the uniformity of the cooling water. The spiral water pipes 309 discharge the cooled water into the water storage chamber 101 from the bottom. Due to the multiple telescopic air cylinders in the same air-cooling component 301 The air intake volume of the cylinder 302 remains highly similar, so the extension amount of the telescopic air cylinder 302 affected by the wind also remains highly similar. By monitoring the bottom heights of multiple telescopic air cylinders 302 in the same air-cooled component 301, when the ratio of the number of telescopic air cylinders 302 with the same height to the total number of telescopic air cylinders 302 is less than the proportional threshold, the telescopic air cylinders 302 with different heights indicate that there is a component failure in the telescopic air cylinder 302, which may be caused by external dust blockage or mechanical damage. When the proportion of the number of intact telescopic air cylinders 302 is lower than a certain proportional threshold, it will affect the overall cooling efficiency, and timely alarms and maintenance are required to ensure the overall cooling efficiency of the air-conditioning system.

[0034] In some optional specific embodiments, such as Figures 4 to 7 As shown, the telescopic air cylinder 302 includes a guide cylinder 3013 embedded in the partition 106, and an inner sleeve 3012 is integrally formed below the guide cylinder 3013. An outer sleeve 3011 is adapted to be provided on the inner sleeve 3012. A movable groove 3015 is provided inside the outer sleeve 3011, and the movable groove 3015 is adapted to the inner sleeve 3012. The outer diameter of the outer sleeve 3011 is the same as the outer diameter of the guide cylinder 3013. The outer sleeve 3011 and the inner sleeve 3012 together constitute an air passage chamber 3016. The bottom of the spiral water pipe 309 extends from the bottom of the air passage chamber 3016 to introduce cold water into the water storage chamber 101. The air inlet of the spiral air pipe 310 is located near the bottom of the air passage chamber 3016 and is used to lead the gas in the air passage chamber 3016 upward. During use, the outer sleeve 3011 and the inner sleeve 3012 together form an air passage cavity 3016. When the airflow in the air passage cavity 3016 is too large, the outer sleeve 3011 and the inner sleeve 3012 move relative to each other, thereby lengthening the spiral water pipe 309, thereby increasing the length of the cold water in the spiral water pipe 309 that is cooled by the air.

[0035] In some optional implementations, such as Figure 5 As shown, a coil spring 3014 is connected between the guide sleeve 3013 and the outer sleeve 3011 . The coil spring 3014 is sleeved on the outer circumference of the outer sleeve 3011 and the inner sleeve 3012 to provide elastic force for the telescopic movement of the outer sleeve 3011 and the inner sleeve 3012 .

[0036] In some optional specific embodiments, such as Figures 5 to 7 As shown, the guide cylinder 3013 is provided with a lifting cylinder 3017, which can move up and down along the guide cylinder 3013, and the lifting cylinder 3017 is connected to a connecting rod 3022, and the top of the connecting rod 3022 is connected to a limiting ring 3023, the inner diameter of the limiting ring 3023 is larger than the inner diameter of the guide cylinder 3013, and at least three groups of support frames 3024 are installed on the top of the guide cylinder 3013, and the support frames 3024 and the top of the guide cylinder 3013 are connected with a torsion spring 3026, and the torsion spring 3026 makes the support frames 3024 always have a tendency to deflect outward, and a flexible sleeve 3025 is connected between the three groups of support frames 3024 and the guide cylinder 3013, and the flexible sleeve 3025 is used to form a guide air outlet for the air cavity 3016, and the limiting ring 3023 is used to limit the deflection angle of the three groups of support frames 3024, thereby controlling the size of the guide air outlet. During use, the height of the lifting cylinder 3017 is controlled to adjust the height of the limit ring 3023, change the interference position between the limit ring 3023 and the support frame 3024, change the deflection angle of the support frame 3024, and finally change the opening size of the guide air outlet formed by the flexible sleeve 3025.

[0037] In some optional specific embodiments, such as Figures 3 to 7As shown, an adjustment track 303 is provided on the circumference of the air cooling component 301, and an adjustment unit 304 is installed on the adjustment track 303. The adjustment unit 304 is signal-connected to a control module. The control module is used to capture the reading of the height sensor, record it as an elongation parameter, compare multiple elongation parameters in the same air cooling component 301, and establish multiple data sets. Elongation parameters with the same elongation parameter are classified into the same data set. After the classification is completed, the data set with the most subsets in the data set is used as the standard data set, and the elongation parameters in the standard data set are used as the standard parameters. The remaining data sets are used as the data sets to be corrected, and the elongation parameters in the data sets to be corrected are used as the parameters to be corrected. The standard parameters are compared with the parameters to be corrected. If the parameters to be corrected are greater than the standard parameters, the control module sends an instruction to control the adjustment unit 304 to drive the lifting cylinder 3017 to move upward, reducing the diameter of the guide air outlet until the parameters to be corrected are equal to the standard parameters. If the parameters to be corrected are less than the standard parameters, the control module sends an instruction to control the adjustment unit 304 to drive the lifting cylinder 3017 to move downward, increasing the diameter of the guide air outlet until the parameters to be corrected are equal to the standard parameters. During use, the chiller may be damaged due to long-term operation, or external dust may enter the interior of the machine and cause an impact, which may cause the affected faulty telescopic air cylinder 302 to have an elongation different from that of the normally working telescopic air cylinder 302 when subjected to the same working wind force. Since the cause of the fault and the degree of impact of the faulty telescopic air cylinder 302 are difficult to be the same, the elongation of the faulty telescopic air cylinder 302 under the same working wind force is not only different from that of the normally working telescopic air cylinder 302, but also has a very small probability of being the same as that of other faulty telescopic air cylinders 302. Therefore, the telescopic parameter with the largest number of identical elongations of the telescopic air cylinder 302 is used as the standard parameter to judge the faulty telescopic air cylinder 302, and to correct and compensate for the air intake.

[0038] In some optional embodiments, the control module is configured to capture the height sensor reading, record it as an elongation parameter, and compare multiple elongation parameters within the same air-cooled assembly 301 to establish multiple data sets. Grouping elongation parameters with identical elongation parameters into the same data set involves defining a fixed threshold a, sorting all elongation parameters, and, starting with the first elongation parameter, grouping subsequent data with a difference less than a into the same data set until a difference exceeds a is encountered, at which point a new group is created. Because in actual operating conditions, even intact telescopic cylinders 302 rarely achieve identical elongation values, a fixed error threshold a is defined. The fixed threshold a can be determined by those skilled in the art based on the specific parameters of the equipment components.

[0039] In some optional embodiments, the control module further includes a distribution unit configured to adjust the diameter of the air guide vents based on the innermost air cooling assembly 301, so that the telescopic air cylinders 302 of all air cooling assemblies 301 extend to the same extent during operation. By controlling the air intake of the telescopic air cylinders 302 in different air cooling assemblies 301, the air intake of the telescopic air cylinders 302 in different wind operating conditions is maintained consistent, thereby improving cooling uniformity.

[0040] In some optional specific embodiments, such as Figures 4 to 7 As shown, a threaded sleeve 3018 is provided on the lifting cylinder 3017, and fixed platforms 3019 are respectively installed on both sides of the threaded sleeve 3018. The fixed platforms 3019 are installed on the partition 106 for supporting the rotation of the threaded sleeve 3018. The outer periphery of the threaded sleeve 3018 is provided with friction lines. The adjusting unit 304 includes a vehicle body 3041 adapted to be installed on the adjusting rail 303. The vehicle body 3041 can move along the adjusting rail 303. An electric telescopic rod 3042 is installed on the vehicle body 3041. The electric telescopic rod 3042 is connected to a drive motor 3043. A drive wheel 3044 is installed on the drive motor 3043. The drive wheel 3044 is adapted to the threaded sleeve 3018. The electric telescopic rod 3042 pushes the drive motor 3043 toward the direction of the threaded sleeve 3018, so that the drive wheel 3044 contacts the threaded sleeve 3018. The driving wheel 3044 contacts the threaded sleeve 3018 and drives the threaded sleeve 3018 to rotate, thereby causing the lifting cylinder 3017 to move up and down along the guide cylinder 3013.

[0041] In some optional embodiments, a guide bar is installed on the inner wall of the lifting cylinder 3017, and the guide bar is arranged along the axial direction of the lifting cylinder 3017. A guide groove adapted to the guide bar is opened on the outer circumference of the guide cylinder 3013 to support the up and down movement of the lifting cylinder 3017.

[0042] In some optional specific embodiments, such as Figures 4 to 7 As shown, a plurality of limiting grooves 3020 are provided at the bottom edge of the threaded sleeve 3018, and a limiting column 3021 is installed on the partition 106. The limiting column 3021 cooperates with the limiting groove 3020 to limit the movement of the threaded sleeve 3018. A pushing rod 3045 is installed on the driving motor 3043, and the pushing rod 3045 is adapted to the limiting column 3021. When the driving wheel 3044 approaches the threaded sleeve 3018, the pushing rod 3045 pushes the limiting column 3021 out of the limiting groove 3020. When the driving wheel 3044 completes driving the threaded sleeve 3018, the pushing rod 3045 retreats, and the limiting column 3021 moves to the limiting groove 3020 at the current position under the action of the reset spring.

[0043] In some optional specific embodiments, such as Figures 1 to 7 As shown, the tops of the multiple spiral water pipes 309 are connected to diversion water pipes 305, and the diversion water pipes 305 are connected to water injection pipes 307. The water injection pipes 307 are used to inject water in the transfer chamber 103 into the multiple spiral water pipes 309. The bottoms of the spiral water pipes 309 are connected to the water storage chamber 101. A spiral air pipe 310 is also installed inside the telescopic air cylinder 302. The top of the spiral air pipe 310 is connected to a ring-shaped converging air pipe 306. The converging air pipes 306 of the multiple air-cooling components 301 are connected to the outlet pipe 308, and the outlet pipe 308 is externally connected to the main exhaust pipe 401.

[0044] In some optional specific embodiments, such as Figure 1 As shown, the transfer chamber 103 is connected to the transfer water pipe 201, the water storage chamber 101 is connected to the water storage pipe 203, a connecting pipe 202 is connected between the water storage pipe 203 and the transfer water pipe 201, and the connecting pipe 202 is connected to the main water pipe 204. The main water pipe 204 is used to lead out the cooled water and introduce the water to be cooled.

[0045] The working principle of the present invention is as follows: during operation, the water in the water storage chamber 101 is introduced into the transfer chamber 103, and the transfer chamber 103 diverts the water to each spiral water pipe 309. By configuring the air-cooling component 301 to include multiple telescopic air cylinders 302, and the multiple telescopic air cylinders 302 are distributed in a circular array with the axis of the rotating shaft of the axial flow fan 105 as the axis, the air intake volume of the multiple telescopic air cylinders 302 on each air-cooling component 301 remains highly similar, and the spiral water pipes 309 in the same air-cooling component 301 are more evenly affected by the wind, thereby greatly improving the uniformity of the cooling water. The spiral water pipes 309 discharge the cooled water into the water storage chamber 101 from the bottom. Due to the multiple The air intake volume of each telescopic air cylinder 302 remains highly similar. Therefore, the extension amount of the telescopic air cylinder 302 affected by the wind also remains highly similar. By monitoring the bottom heights of multiple telescopic air cylinders 302 in the same air-cooled component 301, when the ratio of the number of telescopic air cylinders 302 with the same height to the total number of telescopic air cylinders 302 is less than the proportional threshold, the telescopic air cylinders 302 with different heights indicate that there is a component failure in the telescopic air cylinder 302, which may be caused by external dust blockage or mechanical damage. When the proportion of the number of intact telescopic air cylinders 302 is lower than a certain proportional threshold, it will affect the overall cooling efficiency, and timely alarms and maintenance are required to ensure the overall cooling efficiency of the air-conditioning system.

[0046] Long-term operation of the chiller causes mechanical damage, or external dust enters the interior of the machine and causes an impact, which will cause the affected faulty telescopic air cylinder 302 to have an elongation different from that of the normally working telescopic air cylinder 302 when subjected to the same working wind force. Since the cause of the fault and the degree of impact of the faulty telescopic air cylinder 302 are difficult to be the same, under the same working wind force, its elongation is not only different from that of the normally working telescopic air cylinder 302, but also has a very small probability of being the same as the elongation of other faulty telescopic air cylinders 302. Therefore, the telescopic parameter with the largest number of identical elongations of the telescopic air cylinder 302 is used as the standard parameter to judge the faulty telescopic air cylinder 302, and to correct and compensate for the air intake.

[0047] It should be noted that the methods of one or more embodiments of this specification can be performed by a single device, such as a computer or server. The methods of this embodiment can also be applied in a distributed scenario, where multiple devices cooperate to perform the method. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the methods of one or more embodiments of this specification, and the multiple devices will interact with each other to complete the method.

For example, other memory architectures (e.g., dynamic RAM (DRAM)) may utilize the discussed embodiments.

[0049] The one or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included within the scope of protection of this disclosure.
