Description

Technical Field

[0001] The invention relates to the technical field of water tank liner detection, and in particular to a water tank liner detection system and method for a chiller. Background Art

[0002] A chiller is a device commonly used in refrigeration and air conditioning systems. It is mainly used to provide cold water to help regulate the temperature of buildings or industrial facilities. It removes heat from the air or water through an evaporative refrigeration cycle to produce cold water, which is then supplied to the heat exchange equipment in the system for temperature control. The basic working principle of a chiller is that the compressor compresses the low-pressure and low-temperature refrigerant into a high-pressure and high-temperature gas that enters the condenser. The condenser removes the heat from the refrigerant through cooling water or air, causing the refrigerant to change from gas to liquid. After the liquid refrigerant enters the expansion valve, the pressure drops sharply, and the refrigerant begins to absorb heat and evaporate into gas in the evaporator. The evaporator absorbs heat from the air or water, lowering the temperature of the cold water, and the refrigerant evaporates into gas in the process. The evaporated refrigerant gas returns to the compressor and re-enters the cycle.

[0003] In a water-cooled chiller, the condenser dissipates heat through cooling water. The cooling water usually comes from an external pool or tank and is circulated to the condenser by a pump. In this case, the main function of the tank is to store and provide cooling water to ensure that the condenser can effectively dissipate heat. Long-term contact between the inner tank liner and water, air, and oxygen and chloride ions dissolved in the water may cause corrosion on the inner tank surface, especially for metal tanks. Corrosion will cause the inner tank to become thinner and produce holes, which will eventually affect the sealing and water quality of the tank. Summary of the invention

[0004] In view of the above problems existing in the prior art, the object of the present invention is to provide a chiller water tank liner detection system and method, so as to detect the chiller water tank liner.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water tank liner detection system for a chiller, comprising: a parameter acquisition module, which is used to obtain the number of holes in the water tank liner in real time, and record the number of holes as a basis for subsequent judgment; a threshold setting module, which is used to reasonably set the hole number threshold, and the hole number threshold is the judgment standard whether the water tank liner is still within the safe use range. The number of holes under this hole number threshold is within an acceptable range; a comparison response module, which is used to compare the hole number with the hole number threshold. If the hole number is less than the hole number threshold, it means that the water tank liner can be used normally. In this case, normal operation is maintained; if the hole number is greater than or equal to the hole number threshold, it means that the corrosion of the water tank liner is serious. In this case, an early warning is issued to remind the operator to replace or repair the water tank liner.

[0006] In some embodiments, when the number of holes is greater than or equal to a hole number threshold, further analysis is performed to determine whether there are holes that are about to be perforated to determine whether the water tank liner can continue to be used.

[0007] In some embodiments, the method for determining whether the water tank liner can be barely used is: obtain the depth of all holes, find the hole with the largest depth, record it as the maximum hole depth, and at the same time, set a hole depth threshold, compare the maximum hole depth with the hole depth threshold, and obtain different responses based on the comparison results.

[0008] In some embodiments, if the maximum hole depth is greater than or equal to the hole depth threshold, it means that there is a hole that is about to be punctured in the water tank liner. In this case, the water tank liner cannot be used any more and needs to be repaired or replaced. If the maximum hole depth is less than the hole depth threshold, it means that there is no hole that is about to be punctured in the water tank liner. In this case, the water tank liner can continue to be used any more.

[0009] In some embodiments, when the water tank liner needs to be repaired or replaced, it is further determined whether it is repaired or replaced. The specific method is: after obtaining the depths of all holes, the hole depth of each hole is compared with the hole depth threshold, and the number of holes whose hole depth is greater than or equal to the hole depth threshold is obtained, which is recorded as the number of perforated holes. At the same time, a perforated hole number threshold is set, and the number of perforated holes is compared with the perforated hole number threshold, and different responses are obtained according to the comparison results.

[0010] In some embodiments, if the number of perforated holes is less than the perforated hole number threshold, it means that the number of perforated holes is small and maintenance is not difficult. In this case, the water tank liner is repaired; if the number of perforated holes is greater than or equal to the perforated hole number threshold, it means that the number of perforated holes is large and maintenance is difficult. In this case, the water tank liner is replaced.

[0011] In some embodiments, when the number of perforated holes is greater than or equal to a threshold number of perforated holes, the distribution positions of the perforated holes are obtained, the number of inner wall surfaces of the water tank liner occupied by all the perforated holes is determined, and different responses are taken according to different occupied numbers.

[0012] In some embodiments, if the number of inner wall surfaces of the water tank liner occupied by all the perforated holes is less than or equal to half of the number of inner wall surfaces of the water tank liner, it means that the perforated holes occupy a small area on the water tank liner. In this case, it is determined that maintenance is not difficult and the water tank liner is repaired; if the number of inner wall surfaces of the water tank liner occupied by all the perforated holes is greater than half of the number of inner wall surfaces of the water tank liner, it means that the perforated holes occupy a large area on the water tank liner. In this case, it is determined that maintenance is difficult and the water tank liner is replaced.

[0013] The chiller water tank liner detection system effectively ensures the safety and reliability of the water tank liner through sensor monitoring, reasonable threshold setting and detailed comparative analysis. First, the system helps to determine the degree of corrosion of the water tank liner by real-time monitoring of the number and depth of holes to avoid excessive maintenance or replacement. By reasonably setting the number of holes and hole depth thresholds, the system can make timely and flexible responses when corrosion occurs in the water tank liner, prevent waste of resources due to excessive maintenance, and avoid unnecessary downtime. At the same time, the system can also determine whether to repair or replace the liner based on the number and distribution of perforated holes. If the perforated holes are concentrated and maintenance is relatively easy, the system recommends maintenance instead of direct replacement, saving resources and extending the service life of the water tank. In short, this system ensures the stable operation of the chiller to the greatest extent through accurate judgment and flexible response, reduces unnecessary costs, and optimizes the efficiency of maintenance and replacement decisions.

[0014] The present invention also provides the following technical solutions: The present invention further provides a method for detecting the inner liner of a water tank of a chiller, comprising the following steps: step one, obtaining the number of holes in the inner liner of the water tank, and recording the number of holes as a basis for subsequent judgment; step two, setting a hole number threshold, the hole number threshold being a judgment standard for whether the inner liner of the water tank is still within the safe use range, and the number of holes under this hole number threshold is within an acceptable range; step three, comparing the number of holes with the hole number threshold, if the number of holes is less than the hole number threshold, it means that the inner liner of the water tank can be used normally, in which case, normal operation is maintained; if the number of holes is greater than or equal to the hole number threshold, it means that the inner liner of the water tank is severely corroded, in which case, an early warning is issued to remind the operator to replace or repair the inner liner of the water tank.

[0015] The present invention further provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implement the above-mentioned chiller water tank liner detection system.

[0016] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: First, in the present invention, the number of holes is used as a reference condition for judging whether the water tank liner can continue to be used. If the number of holes is less than the hole number threshold, it indicates that the damage of the water tank liner is acceptable and does not affect the use; if the number of holes is greater than or equal to the hole number threshold, it indicates that the degree of damage to the water tank liner is high and needs to be repaired or replaced.

[0017] Secondly, in the present invention, when the damage degree of the water tank liner is high, the maximum depth of the hole is used as a reference condition to determine whether the water tank liner can continue to be used. If the maximum depth of the hole is greater than or equal to the hole depth threshold, it indicates that the hole in the water tank liner is about to be perforated and cannot be used; if the maximum depth of the hole is less than the hole depth threshold, it indicates that the hole in the water tank liner is not about to be perforated, and the water tank liner can continue to be used and repaired or replaced in idle time. In this way, on the one hand, it can avoid the impact of immediate repair or replacement on the work process; on the other hand, it can also avoid the problem of redundant repair.

[0018] Thirdly, in the present invention, the number of perforated holes is used as a reference condition for judging whether the water tank liner can continue to be used after repair or can only be replaced. If the number of perforated holes is less than the threshold number of perforated holes, it indicates that the number of perforated holes is small, the repair is simple, and the water tank liner can be used again after repair; if the number of perforated holes is greater than or equal to the threshold number of perforated holes, it indicates that the number of perforated holes is large, the repair is difficult, and replacement is required.

[0019] Fourthly, in the present invention, the distribution of perforated holes in the water tank liner is used to further determine whether the water tank liner needs to be repaired or replaced. If the perforated holes occupy a small area on the inner wall of the water tank liner, it indicates that the repair area is small and it can be repaired and then used again; if the perforated holes occupy a large area on the inner wall of the water tank liner, it indicates that the repair area is large and the repair is difficult, so it needs to be replaced. In this way, the water tank liner can be fully utilized to avoid wasting resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic diagram of the module structure of the present invention; Figure 2 It is a logical thinking diagram of the present invention. DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] The water tank liner detection system of the chiller provided by the present invention is as follows: Figure 1 and Figure 2 As shown, including: Parameter acquisition module: In this module, its main function is to monitor and record the corrosion of the water tank liner in real time through sensors, especially the changes in the number of holes. During long-term use, the water tank liner will often corrode due to the influence of factors such as water quality, temperature changes, chemical composition and oxidation. One of the most direct manifestations of corrosion is the appearance of holes on the surface of the liner. These holes not only affect the structural strength of the water tank, but may also cause the water tank to leak. In severe cases, it may even endanger the normal operation of the entire chiller. Therefore, in this module, the number of holes in the water tank liner is obtained in real time through sensors, and the number of holes is recorded as a basis for subsequent judgment.

[0024] Threshold setting module: In this module, it is responsible for providing a judgment standard for the system. By setting the threshold of the number of holes, the system can determine whether the water tank liner is still within the safe use range. This module sets a reasonable threshold of the number of holes based on the historical use of the chiller, empirical data and technical standards. The threshold of the number of holes is determined based on the corrosion resistance of the liner material, the characteristics of the working environment and the design standards of the water tank. Each water tank liner material has different resistance to corrosion. For example, stainless steel materials usually have good corrosion resistance, while carbon steel materials are relatively susceptible to corrosion, so their thresholds of the number of holes will also be different. By analyzing the historical operation data of the chiller, the threshold setting module can use historical maintenance records and fault data to identify the damage mode of the liner under specific use conditions. For example, if in the past use, a certain type of water tank liner has leaked or been severely damaged when 5 holes appeared, the system sets 5 holes as the threshold of the number of holes based on this experience. When the number of holes approaches or exceeds this hole number threshold, the system will predict that the probability of failure of the water tank liner has increased sharply, and issue a warning in time to remind the operator to conduct further inspection, repair or replacement.

[0025] Comparative response module: In this module, the number of holes is compared with the hole number threshold, and different responses are obtained based on the comparison results. If the number of holes is less than the hole number threshold, it means that the number of holes in the water tank liner is still within an acceptable range, the structural integrity of the water tank liner is not significantly affected, and the water tank liner can still be used normally. In this case, the system remains in normal operation and does not require intervention. Only regular follow-up inspections are required to ensure that the condition of the water tank liner does not deteriorate. If the number of holes is greater than or equal to the hole number threshold, it means that the number of holes in the water tank liner has exceeded the acceptable range, the corrosion of the water tank liner has reached a dangerous critical point, and the probability of leakage and damage to the water tank liner has increased significantly. In this case, the system triggers the alarm mechanism to remind the operator that the water tank liner needs to be repaired or replaced.

[0026] In general, the chiller water tank liner detection system ensures the safety and reliability of the water tank liner through three main modules. First, the parameter acquisition module detects the number of holes in the water tank liner in real time through sensors. These holes are a direct manifestation of corrosion, which directly affects the structural strength of the water tank and may even cause leakage, thereby endangering the normal operation of the chiller. Next, the threshold setting module sets a reasonable threshold for the number of holes based on the historical use of the chiller, empirical data and technical standards to determine whether the water tank liner is still within the safe use range. This threshold for the number of holes takes into account the corrosion resistance, working environment and design standards of the liner material, helping the system predict the failure probability of the water tank liner. Finally, the comparison response module compares the number of holes obtained in real time with the set threshold and makes corresponding processing based on the results. If the number of holes is less than the threshold, the water tank liner can still be used normally; if the number of holes exceeds the threshold, it means that the corrosion has reached a dangerous critical point, and the system will trigger an alarm to remind the operator to repair or replace it. Through the collaboration of these three modules, the system can efficiently monitor the health of the water tank liner, issue timely warnings and take corresponding measures to ensure the stable operation of the chiller.

[0027] In addition, when the number of holes in the water tank liner is greater than or equal to the set hole number threshold, although it indicates that the corrosion of the water tank liner has exceeded the acceptable range, it does not mean that all situations must be repaired or replaced immediately. In fact, only when the corrosion holes cause the water tank liner to be perforated or close to perforation will the water tank leak and affect the normal operation of the chiller. If the holes are only partially corroded and have not penetrated the water tank liner, or even if there are a large number of holes, but the degree of corrosion is relatively light, the structural integrity of the liner can still be barely maintained. At this time, the water tank liner can still be barely used, although its condition is not ideal. In addition, the chiller has high requirements for continuity and stability during operation. Sudden shutdown for maintenance or replacement of the water tank liner will affect the operation process of the entire chiller, and may even cause production interruption or unnecessary economic losses. Therefore, when it is detected that the corrosion of the water tank liner has not reached the level of perforation or is about to be perforated, a more flexible response strategy can be adopted. Specifically, after evaluating the degree of corrosion, it can be decided whether to suspend operation based on the actual operation of the unit. If the water tank liner can still barely maintain normal function at this time, you can choose to continue to use it and wait for free time to repair or replace it, so as to reduce interference with the operation of the unit. On the one hand, this approach can ensure that the chiller does not waste resources due to excessive maintenance and avoid meaningless shutdown maintenance; on the other hand, it can also effectively avoid waste of resources and redundant maintenance caused by corrosion problems. The specific method for judging whether the water tank liner of the chiller can continue to be barely used is: when the number of holes is greater than or equal to the hole number threshold, the depth of all holes is obtained by the sensor, and the depth of all holes is arranged in order from large to small. The hole with the largest depth is found and recorded as the maximum depth of the hole, and the maximum depth of the hole is recorded as the basis for subsequent judgment. In addition, the hole depth threshold is set according to the parameter information of the water tank liner. This hole depth threshold is the maximum hole depth that the water tank liner can barely use. When the hole depth of the water tank liner reaches this hole depth threshold, it indicates that the hole is about to be perforated. Based on the above conditions, the maximum hole depth is compared with the hole depth threshold, and different responses are obtained according to the comparison results. If the maximum hole depth is greater than or equal to the hole depth threshold, it means that among all the corroded holes in the water tank liner, some holes are about to be punched. In this case, the water tank liner cannot be used any more, and the system needs to be shut down immediately to repair or replace the water tank liner. If the maximum hole depth is less than the hole depth threshold, it means that among all the corroded holes in the water tank liner, no holes are about to be punched, and all the corroded holes are still within an acceptable range. In this case, the water tank liner can continue to be used, and after the work is completed, the water tank liner can be repaired or replaced in spare time. In summary, when the number of holes in the water tank liner reaches or exceeds the set hole number threshold, it does not mean that it must be repaired or replaced immediately.Only when the corrosion holes cause the inner tank to be perforated or close to perforation, will the normal use of the water tank be affected, leading to leakage. If the holes have not penetrated the inner tank of the water tank, even if there are a large number of holes, the inner tank structure can still barely maintain normal use. During the operation of the chiller, sudden shutdown for maintenance may affect the production progress and even cause unnecessary economic losses. Therefore, when corrosion has not yet caused perforation, it can be flexibly responded to according to the operating conditions of the unit. The specific method is to monitor the hole depth through the sensor, sort the hole depth by size, find the hole with the maximum depth, and record it as the maximum hole depth. At the same time, set a hole depth threshold, which indicates the maximum hole depth that the water tank liner can barely use. If the maximum hole depth reaches or exceeds this threshold, it indicates that there are holes close to perforation, and the water tank liner needs to be shut down for maintenance or replaced immediately; if the maximum depth is less than the threshold, it means that the corrosion is still within an acceptable range, and the water tank liner can continue to be used and repaired when it is idle. Through this method, the system can avoid excessive maintenance and waste of resources, while ensuring that the water tank liner continues to operate stably within a safe range.

[0028] After judging whether the water tank liner needs to be repaired or replaced according to the size of the hole depth, it is necessary to further judge whether the water tank liner can continue to be used after repair or needs to be replaced. For this aspect, the most direct way to judge is to judge according to the number of perforated holes. If the number of perforated holes is large and it is not easy to repair, it needs to be replaced. If the number of perforated holes is small and it can continue to be used after simple repair, it only needs to be repaired. Specifically, after obtaining the depth of all holes through the sensor, the hole depth of each hole is compared with the hole depth threshold, and the number of holes with a hole depth greater than or equal to the hole depth threshold is obtained. Here, the holes that are about to be perforated are regarded as perforated holes. In addition, according to the actual difficulty of maintenance, a perforated hole number threshold is set, and the number of perforated holes is compared with the perforated hole number threshold, and different responses are obtained according to the comparison results. If the number of perforated holes is less than the perforated hole number threshold, it means that the number of perforated holes is small and maintenance is not difficult. In this case, the water tank liner is repaired. If the number of perforated holes is greater than or equal to the threshold number of perforated holes, it means that there are a large number of perforated holes and repair is difficult. In this case, the water tank liner should be replaced.

[0029] In the above situation, when the number of perforated holes is greater than or equal to the threshold of the number of perforated holes, it is determined that the number of perforated holes is large and difficult to repair. The choice of treatment for the water tank liner is to replace it. However, if these perforated holes are concentrated in a certain area of ​​the water tank liner, and there are no perforated holes in most other areas, it also means that the repair is not difficult. Because the inner wall of the water tank liner generally has four faces, if only one or two faces have perforated holes, and the other faces have no perforated holes, in this case, if it is directly replaced, it is equivalent to wasting other faces without perforated holes. Therefore, a re-judgment is made here. The process of re-judgment is: obtain the distribution position of all perforated holes through the sensor, determine the number of inner wall surfaces of the water tank liner occupied by all perforated holes, and make different responses according to the different occupied numbers. If the number of inner wall surfaces of the water tank liner occupied by all perforated holes is less than or equal to half of the number of inner wall surfaces of the water tank liner, it means that the perforated holes occupy a small area on the water tank liner. In this case, it is determined that it is not difficult to repair and the water tank liner is repaired. If the number of inner wall surfaces of the water tank liner occupied by all the perforated holes is greater than half of the inner wall surfaces of the water tank liner, it means that the perforated holes occupy a large area on the water tank liner. In this case, it is considered difficult to repair and the water tank liner needs to be replaced.

[0030] In general, the detection system of the water tank liner of the chiller not only pays attention to the changes in the number of corrosion holes, but also determines whether it needs to be repaired or replaced through detailed analysis. First, the system monitors the hole depth of the water tank liner through sensors, obtains the maximum hole depth, and determines whether the hole is close to perforation based on the set hole depth threshold. Next, the system will determine whether it can continue to be used through repair based on the number of perforated holes. If the number of perforated holes is small and the repair is simple, it can be repaired; if the number of perforated holes is large and the repair is difficult, it is necessary to consider replacing the liner. However, the judgment of whether to replace is not only based on the number of perforated holes, but also on the distribution of perforated holes. If the perforated holes are concentrated in a certain area of ​​the water tank liner, and there are no perforated holes in other areas, it means that the repair difficulty is low, and it is completely possible to choose to repair without replacing the entire liner. For further judgment, the system will calculate the proportion of the inner wall surface of the water tank liner occupied by the perforated holes based on the distribution position of the perforated holes. If the number of holes in the inner wall of the water tank is less than or equal to half, it means that the perforated area is relatively small and maintenance work can be carried out; if the number of holes in the inner wall exceeds half, it means that the damage is serious and the maintenance is difficult. At this time, the water tank needs to be replaced. Through this detailed judgment method, the system can optimize resource utilization and avoid unnecessary replacement or maintenance, thereby ensuring the normal operation and economic benefits of the chiller.

The chiller water tank liner detection method according to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: Obtain the number of holes in the inner tank of the water tank and record the number of holes as a basis for subsequent judgment; Step 2: Setting a hole number threshold, which is a criterion for judging whether the water tank liner is still within the safe use range. The number of holes under this hole number threshold indicates that it is within an acceptable range. Step three, compare the number of holes with the hole number threshold. If the number of holes is less than the hole number threshold, it means that the water tank liner can be used normally. In this case, maintain normal operation; if the number of holes is greater than or equal to the hole number threshold, it means that the water tank liner is severely corroded. In this case, an early warning is issued to remind the operator to replace or repair the water tank liner.

10. A computer-readable storage medium, characterized in that: The computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implement a chiller water tank liner detection system as described in any one of claims 1 to 8.
