[0002] Air conditioning system is an important technology for regulating space temperature, which provides great convenience for special processing, medical treatment and daily life. As the core refrigeration equipment of central air conditioning system, the performance of water chiller directly affects the operation efficiency of the whole system. The compound water chiller integrates multiple refrigeration methods and intelligently switches the cold source under different working conditions, which significantly improves the energy efficiency of the system.

[0003] The Chinese invention patent with publication number CN119309265A provides a shell assembly for a chiller and 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, a cooling and heat exchange space can be provided. In conjunction with the dispersion of clean water by a water distribution pipe and the entry of external cooling media, the clean water can be efficiently cooled and cooled by utilizing the structural improvement during the circulation of clean water in the shell.

[0004] However, the applicant has found that the prior art has at least the following problems: Since the wind force provided by the axial flow fan is not uniform on its action surface, the wind force in multiple air cavities will vary greatly.

[0022] One or more embodiments of the present 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 arranged inside the shell, the transfer chamber 103 is arranged above the water storage chamber 101, and the air cooling chambers 102 are arranged 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, and is used to introduce the cold water in the water storage chamber 101 into the transfer chamber 103, and an air inlet 104 is arranged on the top of the air cooling chamber 102, and an axial flow fan 105 is arranged on the air inlet 104; a partition 106 is arranged 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 are 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; The air cooling assembly 301 includes a plurality of telescopic air cylinders 302, which are arranged in a circular array with the axis of the rotating shaft of the axial flow fan 105 as the axis. A spiral water pipe 309 is installed inside the telescopic air cylinder 302 for returning the 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, and the spiral air pipe 310 draws the air inside the telescopic air cylinder 302 upward from the bottom and finally discharges it to the outside of the shell; A height sensor is provided at the bottom of the telescopic air cylinder 302 for 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 bottom height in the same air-cooled component 301 to the total number of telescopic air cylinders 302 is less than a ratio threshold, an alarm signal is sent, otherwise no alarm signal is sent.

[0023] During operation, water in the water storage chamber 101 is introduced into the transfer chamber 103, and the transfer chamber 103 divides the water into each spiral water pipe 309. By configuring the air-cooling component 301 to include a plurality of telescopic air cylinders 302, and the plurality of 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 plurality of telescopic air cylinders 302 on each air-cooling component 301 is kept highly similar, and the spiral water pipes 309 in the same air-cooling component 301 are more evenly exposed to wind, thereby greatly improving the uniformity of cooling water. The spiral water pipes 309 discharge the air-cooled water into the water storage chamber 101 from the bottom. The air intake volume of the 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 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.

[0024] 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, 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, 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 chamber 3016, the bottom of the spiral water pipe 309 extends out from the bottom of the air chamber 3016 to introduce cold water into the water storage chamber 101, and the air inlet of the spiral air pipe 310 is located near the bottom of the air chamber 3016 to lead the gas in the air chamber 3016 upward. When in use, the outer sleeve 3011 and the inner sleeve 3012 together form an air chamber 3016. When the airflow in the air chamber 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.

[0025] In some optional specific 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 .

[0026] In some optional specific embodiments, such as Figures 5 to 7 As shown, a lifting cylinder 3017 is sleeved on the guide cylinder 3013, and the lifting cylinder 3017 can move up and down along the guide cylinder 3013, and the lifting cylinder 3017 is connected to a connecting rod 3022, and a limiting ring 3023 is connected to the top of the connecting rod 3022, and 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 torsion springs 3026, and the torsion springs 3026 make the support frames 3024 always have a tendency to deflect outward, and flexible sleeves 3025 are connected between the three groups of support frames 3024 and the guide cylinder 3013, and the flexible sleeves 3025 are used to form a guide air outlet for the air cavity 3016, and the limiting rings 3023 are used to limit the deflection angles 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.

[0027] In some optional specific embodiments, such as Figures 3 to 7As shown, an adjustment track 303 is provided on the peripheral side 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, and compare multiple elongation parameters in the same air-cooling component 301, and establish multiple data sets. The elongation parameters with the same elongation parameters 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, the elongation parameters in the standard data set are the standard parameters, and the remaining data sets are the data sets to be corrected, and the elongation parameters in the data sets to be corrected are 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, reduce 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, increase 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. This may cause the affected telescopic air cylinder 302 to have an elongation that is different from that of the telescopic air cylinder 302 that is working normally when subjected to the same wind force. The faulty telescopic air cylinder 302 has an elongation that is different from that of the telescopic air cylinder 302 that is working normally because its cause of failure and degree of impact are difficult to be the same. Therefore, under the same wind force, the elongation of the telescopic air cylinder 302 is not only different from that of the telescopic air cylinder 302 that is working normally, 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 determine the faulty telescopic air cylinder 302, and to correct and compensate for the air intake.

[0028] In some optional specific embodiments, the control module is used to capture the reading of the height sensor, record it as an elongation parameter, and compare multiple elongation parameters in the same air-cooled component 301, and establish multiple data sets. The elongation parameters with the same elongation parameters are classified into the same data set, including defining a fixed threshold a, sorting all elongation parameters, starting from the first elongation parameter, and classifying subsequent data with a difference less than a from it into the same data set until data with a difference exceeding a is encountered, and a new group is opened. Because in actual working conditions, even the elongation of a complete telescopic cylinder 302 is difficult to achieve exactly the same amount, a fixed error threshold a is given, and the fixed threshold a can be determined by a person skilled in the art according to the specific parameters of the equipment parts.

[0029] In some optional specific embodiments, the control module further includes a distribution unit, which is used to adjust the diameter of the air guide port based on the innermost air cooling component 301, so that the telescopic air cylinders 302 of all air cooling components 301 have the same extension during operation. By controlling the air intake of the telescopic air cylinders 302 in different air cooling components 301, the air intake of the telescopic air cylinders 302 in different wind working conditions is changed so that the air intake of the telescopic air cylinders 302 is kept consistent, thereby improving the uniformity of cooling.

[0030] 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 to support the rotation of the threaded sleeve 3018. The outer periphery of the threaded sleeve 3018 is provided with friction lines. The adjustment unit 304 includes a vehicle body 3041 adapted to be installed on the adjustment track 303, and the vehicle body 3041 can move along the adjustment track 303. An electric telescopic rod 3042 is installed on the vehicle body 3041, and the electric telescopic rod 3042 is connected to a driving motor 3043. A driving wheel 3044 is installed on the driving motor 3043, and the driving wheel 3044 is adapted to the threaded sleeve 3018. The electric telescopic rod 3042 pushes the driving motor 3043 toward the direction of the threaded sleeve 3018, so that the driving wheel 3044 contacts the threaded sleeve 3018. The driving wheel 3044 contacts the threaded sleeve 3018 and drives the threaded sleeve 3018 to rotate, so that the lifting cylinder 3017 moves up and down along the guide cylinder 3013.

[0031] In some optional specific 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.

[0032] In some optional specific embodiments, such as Figures 4 to 7 As shown, a plurality of limit grooves 3020 are provided at the bottom edge of the threaded sleeve 3018, and a limit column 3021 is installed on the partition 106, and the limit column 3021 cooperates with the limit groove 3020 to limit the movement of the threaded sleeve 3018, and a pushing rod 3045 is installed on the driving motor 3043, and the pushing rod 3045 is adapted to the limit column 3021. When the driving wheel 3044 approaches the threaded sleeve 3018, the pushing rod 3045 pushes the limit column 3021 out of the limit groove 3020. When the driving wheel 3044 completes driving the threaded sleeve 3018, the pushing rod 3045 retreats, and the limit column 3021 moves to the limit groove 3020 at the current position under the action of the reset spring.

[0033] 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, 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, and 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 an annular 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.

[0034] 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, the connecting pipe 202 is connected to the main water pipe 204, and the main water pipe 204 is used to lead out the cooled water and introduce the water to be cooled.

[0035] Working principle of the present invention: During operation, water in the water storage chamber 101 is introduced into the transfer chamber 103, and the transfer chamber 103 distributes the water to each spiral water pipe 309. By configuring the air cooling component 301 to include a plurality of telescopic air cylinders 302, and the plurality of 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 plurality of telescopic air cylinders 302 on each air cooling component 301 is kept highly similar, and the spiral water pipes 309 in the same air cooling component 301 are more evenly exposed to wind, thereby greatly improving the uniformity of cooling water. The spiral water pipes 309 discharge the air-cooled water into the water storage chamber 101 from the bottom. The air intake volume of each telescopic air cylinder 302 remains highly similar, so the elongation 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 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.

[0036] 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 that is different from the elongation of the normally working telescopic air cylinder 302 when subjected to the same wind force. The faulty telescopic air cylinder 302, because its failure cause and impact degree are difficult to be the same, has an elongation that is not only different from the elongation of the normally working telescopic air cylinder 302 under the same wind force, 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.
