Description

Technical Field

[0001] This application belongs to the field of HVAC equipment technology, specifically relating to a condenser cleaning method, condenser device, temperature control unit and energy storage system. Background Technology

[0002] Currently, condensers are generally used in the heat exchange systems of temperature-controlled units. As a type of heat exchanger, condensers typically exchange heat with the outside air, converting the gaseous heat exchange medium inside into a liquid state. Therefore, condensers are usually in contact with the external space, and dust or lint from the outside environment can easily accumulate, causing condenser blockage and affecting its heat exchange efficiency.

[0003] In related technologies, the cleaning process of condensers has a low degree of automation and requires manual assistance, which not only results in high cleaning costs but also low cleaning efficiency. Summary of the Invention

[0004] The purpose of this application is to at least solve the problems of low efficiency and high cost associated with manual cleaning of condensers. This purpose is achieved through the following methods: In a first aspect, this application proposes a method for cleaning a condenser, the condenser having an air inlet side and an air outlet side, the air inlet side being provided with a cleaning mechanism, and the air outlet side being provided with a fan, the method for cleaning the condenser comprising: Control the fan to rotate in a first direction and operate at a preset power for a preset duration; Obtain the air pressure difference on both sides of the condenser in the thickness direction; The cleaning mechanism is controlled to perform cleaning actions based on the air pressure difference being greater than or equal to a preset pressure difference. Wherein, the preset pressure difference is a positive number, and when the fan rotates along the first direction, the airflow flows from the air inlet side to the air outlet side.

[0005] According to the condenser cleaning method provided in this application, by controlling the fan to operate in the first direction at a preset power for a preset time, the airflow is made to flow from the air inlet side to the air outlet side of the condenser. At this time, the airflow is in a stable flow state, which reduces the interference of airflow fluctuations on the differential pressure data during the fan start-up and shutdown phases. Moreover, the air differential pressure measured in this process can more accurately reflect the actual degree of dirt blockage in the condenser. After the air differential pressure is formed on both sides of the thickness direction of the condenser, the air differential pressure is read and compared with the preset differential pressure. If the read air differential pressure is greater than or equal to the preset differential pressure, it indicates that there is serious dirt blockage on the surface of the condenser, which leads to a reduction in the heat exchange efficiency of the condenser. At this time, the cleaning mechanism is controlled to perform a cleaning action to clean the surface of the condenser and improve the dirt blockage on the surface of the condenser, thereby helping to improve the heat exchange efficiency of the condenser.

[0006] In addition, the condenser cleaning method according to this application may also have the following additional technical features: In some embodiments of this application, the condenser is used in a temperature-controlled unit, which includes a compressor and an evaporator.

[0031] Please see Figure 1 This application proposes a method for cleaning a condenser, which has an air inlet side and an air outlet side. A cleaning mechanism is provided on the air inlet side, and a fan is provided on the air outlet side. The method for cleaning the condenser includes: Step S10: Control the fan to rotate in the first direction and operate at a preset power for a preset time.

[0032] Step S12: Obtain the air pressure difference on both sides of the condenser in the thickness direction.

[0033] Step S14: Control the cleaning mechanism to perform cleaning actions based on the air pressure difference being greater than or equal to the preset pressure difference.

[0034] Wherein, the preset pressure difference is a positive number, and when the fan rotates in the first direction, the airflow flows from the air inlet side to the air outlet side.

[0035] In this embodiment, a first pressure detection point can be arranged on the side of the condenser with the fan, and a first air pressure sensor can be installed at the first pressure detection point to detect the air pressure on the condenser outlet side. A second pressure detection point can be arranged on the side of the condenser with the cleaning mechanism, and a second air pressure sensor can be installed at the second pressure detection point to detect the air pressure on the condenser inlet side. The air pressure difference between the two sides of the condenser can be determined by calculating the difference between the two air pressures.

[0036] In some embodiments, there can be multiple first pressure detection points, which evenly cover the air outlet side of the condenser. Each first pressure detection point is equipped with a first air pressure sensor. The air pressure detected by the multiple first air pressure sensors is acquired, and the average value is taken as the air pressure on the air outlet side of the condenser. Similarly, there can be multiple second pressure detection points, which evenly cover the air inlet side of the condenser. Each second pressure detection point is equipped with a second air pressure sensor. The air pressure detected by the multiple second air pressure sensors is acquired, and the average value is taken as the air pressure on the air inlet side of the condenser. As an example, the preset pressure difference can be set in the range of 200Pa-300Pa, for example, 240Pa, 250Pa, etc.

[0037] As an example, the preset power of the fan can be set to operate at 100% power.

[0038] As an example, the preset duration can be set in the range of 2 minutes to 10 minutes, for example, 3 minutes, 5 minutes, etc.

[0039] According to the condenser cleaning method provided in this application, by controlling the fan to operate in the first direction for a preset duration at a preset power, the airflow is driven to flow from the air inlet side to the air outlet side of the condenser. At this time, the airflow is in a stable flow state, reducing the interference of airflow fluctuations on the differential pressure data during the fan start-up and shutdown phases. Moreover, the air differential pressure measured in this process can more accurately reflect the actual degree of dirt and blockage in the condenser. After an air differential pressure is formed on both sides of the condenser in the thickness direction, the air differential pressure is read and compared with the preset differential pressure. If the read air differential pressure is greater than or equal to the preset differential pressure, it indicates that there is serious dirt and blockage on the surface of the condenser, which leads to a reduction in the heat exchange efficiency of the condenser. At this time, the cleaning mechanism is controlled to perform a cleaning action to clean the surface of the condenser and improve the dirt and blockage on the surface of the condenser, thereby helping to improve the heat exchange efficiency of the condenser.

[0040] According to some embodiments of this application, a condenser is used in a temperature-controlled unit, which includes a compressor and an evaporator. The compressor, condenser, and evaporator are connected in sequence via refrigerant piping. The cleaning method for the condenser further includes: Obtain the operating status of the compressor; The cleaning mechanism is controlled to perform cleaning actions when the compressor is stopped and the air pressure difference is greater than the preset pressure difference.

[0041] Before controlling the cleaning mechanism to perform cleaning actions, it is necessary to obtain the compressor's operating status to determine whether the temperature control unit is in a state of temperature regulation of the target area. Understandably, if the compressor is running, it means the temperature control unit is regulating the temperature of the target area, and in this case, the compressor needs to continue running without performing cleaning actions. Once the temperature of the target area reaches the preset temperature threshold, the compressor stops running, and this can be recorded as the compressor being in a stopped state before the cleaning mechanism is controlled to perform cleaning actions.

[0042] In some embodiments, the condenser cleaning method further includes: obtaining the condensing pressure at the inlet end of the condenser, and controlling the cleaning mechanism to perform a cleaning action based on the condensing pressure being greater than or equal to a preset condensing pressure threshold and the air pressure being greater than or equal to a preset air pressure difference.

[0043] As an example, the preset condensation pressure can be set in the range of 3.5MPa-4.05MPa. For example, 3.6 MPa, 3.8 MPa, etc. can be selected.

[0044] Understandably, the condensing pressure at the inlet of the condenser is equivalent to the discharge pressure at the outlet of the compressor. When the condensing pressure at the inlet of the condenser is greater than the preset condensing pressure threshold, it indicates that the heat exchange efficiency may be reduced due to dirt blockage on the surface of the condenser. At this time, combined with the fact that the air pressure difference on both sides of the condenser in the thickness direction reaches the preset air pressure difference, it is further determined that there is a need for cleaning, and then the cleaning mechanism is controlled to perform the cleaning action.

[0045] According to some embodiments of this application, after the step of controlling the cleaning mechanism to perform the cleaning action, the condenser cleaning method further includes: Control the fan to operate in a second direction, which is opposite to the first direction.

[0046] After the cleaning mechanism performs the cleaning action, it controls the fan to rotate in a second direction opposite to the first direction, so that the airflow can flow from the side of the condenser with the cleaning mechanism to the side where the fan is located, thereby blowing away the dust or lint and other impurities that fall off when the cleaning mechanism cleans the condenser, thus improving the cleaning efficiency of the condenser.

[0047] According to some embodiments of this application, the condenser cleaning method further includes: controlling the cleaning mechanism and fan to stop operating when the air pressure difference is less than a preset pressure difference.

[0048] When the air pressure difference between the two sides of the condenser in the thickness direction is less than the preset pressure difference, it indicates that the dirt blockage on the condenser surface has been improved. At this time, the cleaning mechanism can be controlled to stop cleaning and the fan can be controlled to stop running.

[0049] According to some embodiments of this application, the condenser cleaning method further includes: Read the number of times the cleaning agency performed the cleaning action; If the number of cleaning actions exceeds the preset number and the air pressure difference is greater than or equal to the preset pressure difference, the cleaning mechanism will stop operating and an alarm command will be issued.

[0050] Specifically, one cleaning action is performed when the cleaning component moves back and forth once in the first direction.

[0051] Each time a cleaning action is performed, the air pressure difference between the current air inlet and outlet sides of the condenser is compared with the preset pressure difference to determine whether the cleaning is in place. If the air pressure difference is greater than or equal to the preset pressure difference, the cleaning action continues until the number of cleaning actions exceeds the preset number and the air pressure difference is still greater than or equal to the preset pressure difference. If this condition is not met, the cleaning component is deemed to be faulty and unable to clean properly. An alarm command is then issued to check or replace the cleaning component.

[0052] According to some embodiments of this application, the condenser cleaning method further includes: If the number of cleaning actions is less than or equal to the preset number, and the air pressure difference is less than the preset pressure difference, the cleaning mechanism will stop operating and the number of cleaning actions will be reset to zero.

[0053] If the number of cleaning actions is within the preset number and the air pressure difference between the air inlet and outlet sides of the condenser is less than the preset pressure difference, then the cleaning is considered complete. At this time, the cleaning mechanism is controlled to stop running and the number of cleaning actions is reset to zero.

[0054] Please see Figure 2 According to some embodiments of this application, a condenser device 100 is proposed, including: a first mounting plate 10, a condenser 20, and a cleaning mechanism. The condenser 20 is disposed on one side of the first mounting plate 10 along its thickness direction; the cleaning mechanism is disposed on the first mounting plate 10 and located on one side of the condenser 20 along its thickness direction. The cleaning mechanism includes a bracket, a cleaning component 40, and a drive assembly 50. The cleaning component 40 is disposed on the bracket and is used to clean the condenser 20. The drive assembly 50 is connected to the bracket and is used to drive the bracket and the cleaning component 40 to reciprocate along a first direction, which intersects the thickness direction.

[0055] As an example, the condenser 20 includes a frame, a distribution pipe, multiple fins and multiple condenser tubes. The multiple fins are spaced apart along the frame and fixed to the outer surface of the condenser tubes in the form of sleeves. The distribution pipe is connected to the multiple condenser tubes and is used to distribute liquid into the multiple condenser tubes.

[0056] According to the condenser device 100 proposed in this application, the condenser 20 is installed on one side of the thickness direction of the first mounting plate 10. By adding a cleaning mechanism to the first mounting plate 10, the cleaning mechanism is located on one side of the thickness direction of the condenser 20. The cleaning mechanism includes a bracket and a cleaning component 40 disposed on the bracket, as well as a drive assembly 50 connected to the bracket. The drive assembly 50 can drive the bracket and the cleaning component 40 to reciprocate relative to the first mounting plate 10 in a first direction to clean the surface of the condenser 20, thereby improving the dirt and blockage on the surface of the condenser 20 and helping to improve the heat exchange efficiency of the condenser 20. Moreover, for the condenser 20 installed in a small space, manual cleaning is very inconvenient. The technical solution of this application can clean the condenser 20 without the need for manual assistance, thereby reducing labor costs and helping to improve the cleaning efficiency of the condenser 20.

[0057] Please see Figure 2 According to some embodiments of this application, the bracket includes a first bracket 31 and a second bracket 32. The second bracket 32 ​​and the first bracket 31 are spaced apart along a first direction and both extend along the height direction of the condenser 20. One end of the first bracket 31 is fixedly connected to the first mounting plate 10, and one end of the second bracket 32 ​​is movably connected to the first mounting plate 10. A cleaning component 40 is disposed on the second bracket 32. A driving component 50 is disposed between the second bracket 32 ​​and the first bracket 31 and is connected to the first bracket 31 and the second bracket 32 ​​respectively. The driving component 50 is configured to drive the second bracket 32 ​​to reciprocate along the first direction.

[0058] In this embodiment, the travel of the second support 32 covers the dimension of the condenser 20 along the first direction.

[0059] The bracket includes a first bracket 31 fixedly connected to the first mounting plate 10, and a second bracket 32 ​​capable of reciprocating relative to the first mounting plate 10 along a first direction. By placing the cleaning component 40 on the second bracket 32 ​​and connecting the drive assembly 50 to the first bracket 31 and the second bracket 32 ​​respectively, the drive assembly 50 drives the second bracket 32 ​​to reciprocate along the first direction. The cleaning component 40 moves synchronously with the second bracket 32 ​​and can clean the condenser 20 during the reciprocating motion along the first direction.

[0060] Please see Figure 2 According to some embodiments of this application, the drive assembly 50 includes at least one telescopic link assembly 51, which is hinged to the first bracket 31 and the second bracket 32 ​​on both sides along a first direction, and each telescopic link assembly 51 includes a first link and a second link, with the middle portion of the first link and the middle portion of the second link of each telescopic link assembly 51 pivotally connected.

[0061] According to some embodiments of this application, there are multiple telescopic link assemblies 51, which are arranged along a first direction. One end of the first link of one of two adjacent telescopic link assemblies 51 is hinged to one end of the second link of the other, and one end of the second link of one of two adjacent telescopic link assemblies 51 is hinged to one end of the first link of the other.

[0062] When the drive assembly 50 performs the drive action, the first link and the second link pivot around the center to drive the telescopic link assembly 51 to extend or shorten as a whole, and pull the second bracket 32 ​​to move along the first direction. The telescopic link assembly 51 can make the reciprocating movement of the cleaning component 40 smoother and reduce the possibility of jamming. At the same time, the telescopic link assembly 51 can provide stable support for the second bracket 32, reduce the swaying amplitude of the cleaning component 40 during the movement, and improve the stability of the cleaning process of the cleaning component 40.

[0063] Please see Figure 2 According to some embodiments of this application, the first bracket 31 has a first mounting groove 311 on the side facing the second bracket 32, and the second bracket 32 ​​has a second mounting groove 321 on the side facing the first bracket 31. A plurality of telescopic linkage assemblies 51 include a first telescopic linkage assembly 51 and a second telescopic linkage assembly 51. The first telescopic linkage assembly 51 and the second telescopic linkage assembly 51 are respectively located on both sides of the plurality of telescopic linkage assemblies 51 along a first direction. One end of the first link in the first telescopic linkage assembly 51 is embedded in the first mounting groove and configured as a movable end. One end of the second link in the first telescopic linkage assembly 51 is embedded in the first mounting groove 311 and hinged to the first bracket 31. One end of both the first link and the second link in the second telescopic linkage assembly 51 are embedded in the second mounting groove 321 and hinged to the second bracket 32. The movable end is configured to reciprocate along the first mounting groove 311 to drive the drive assembly 50 to extend or retract.

[0064] Specifically, the first mounting groove 311 and the second mounting groove 321 both extend along the height direction of the first bracket 31 and the second bracket 32.

[0065] Understandably, when one of the multiple telescopic linkage assemblies 51 moves, it will drive the adjacent telescopic linkage assemblies 51 to move synchronously through the hinge point. This not only extends the overall telescopic stroke of the telescopic linkage assembly 51 to adapt to the cleaning needs of condensers 20 of different sizes and specifications, but also distributes the force to multiple telescopic linkage assemblies 51, reducing the stress on a single telescopic linkage assembly 51 and helping to extend the service life of the drive assembly 50.

[0066] When the movable end moves back and forth along the first mounting groove 311, it will drive the first connecting rod and the second connecting rod to pivot around the pivot connection position, so that the telescopic connecting rod assembly 51 can be extended or shortened. The first mounting groove 311 and the second mounting groove 321 play a guiding role, which helps to reduce the positional deviation of the telescopic connecting rod assembly 51. At the same time, the movement trajectory of the movable end can accurately control the movement range of the cleaning part 40, so that the cleaning area is more in line with the dirt distribution area of ​​the condenser 20.

[0067] Please see Figure 2 According to some embodiments of this application, the drive assembly 50 further includes a drive member 52, which is disposed at one end of the first bracket 31 away from the first mounting plate 10. The power output end of the drive member 52 is connected to the movable end and is used to drive the movable end to reciprocate along the first mounting groove.

[0068] As an example, the drive unit 52 can be a linear motor or a stepper motor.

[0069] When the drive unit 52 is activated, the power output end of the drive unit 52 will push the movable end to move back and forth along the first mounting groove, thereby causing the telescopic linkage assembly 51 to extend or shorten. In the process of power transmission, the drive unit 52 can precisely control the moving speed and stroke of the movable end, so that the moving rhythm of the cleaning component 40 can be adapted to the degree of dirt and blockage of the condenser 20, and can also reduce the interference of movement to other components.

[0070] In some embodiments, a sliding block is provided in the first mounting groove. The sliding block is connected to the power output end of the drive member 52, and the movable end is hinged to the slider. The drive member 52 is used to drive the slider to reciprocate along the first mounting groove.

[0071] Please see Figure 2 According to some embodiments of this application, a guide connection portion 11 is provided on one side of the first mounting plate 10. The guide connection portion 11 extends along a first direction. The first bracket 31 is fixedly connected to the guide connection portion 11, and the second bracket 32 ​​is movably connected to the guide connection portion 11 and is adapted to reciprocate relative to the first mounting plate 10 along the first direction.

[0072] As an example, the guide connection 11 is a guide groove.

[0073] When the drive assembly 50 moves the second bracket 32, the second bracket 32 ​​will reciprocate relative to the first mounting plate 10 along the extension direction of the guide connection 11. The guide connection 11 can provide an installation reference for the first bracket 31 and the second bracket 32, which improves the stability of the second bracket 32 ​​when it moves relative to the first mounting plate 10. At the same time, the guide connection 11 can constrain the movement trajectory of the second bracket 32, further reducing the risk of shaking when the cleaning component 40 is cleaning.

[0074] Please see Figure 3 and Figure 4 According to some embodiments of this application, the cleaning component 40 includes a cleaning bracket 41 and a cleaning brush 42 disposed on the cleaning bracket 41. The cleaning bracket 41 is disposed on the second bracket 32, and the cleaning brush 42 is disposed toward the condenser 20.

[0075] As an example, the cleaning bracket 41 and the second bracket 32 ​​are detachably connected, which facilitates the subsequent disassembly and replacement of the cleaning component 40.

[0076] When the second bracket 32 ​​reciprocates along the first direction with the drive assembly 50, the cleaning brush 42 moves synchronously with the second bracket 32 ​​and contacts the surface of the condenser 20 to clean the dirt on the fins and outer surface of the condenser tubes of the condenser 20, so as to help keep the heat exchange channel of the condenser 20 unobstructed.

[0077] Please see Figure 3 and Figure 4 According to some embodiments of this application, the cleaning brush 42 includes a straight brush head or a roller brush head.

[0078] If the cleaning brush 42 uses a straight brush head, when the cleaning component 40 moves with the second bracket 32, the bristles of the straight brush head will embed into the gaps between the fins of the condenser 20, cleaning the dirt in the gaps as the bracket reciprocates. If the cleaning brush 42 uses a roller brush head, the roller brush head will roll with the contact surface when the bracket moves, increasing the contact area with the surface of the condenser 20. It can be adapted to scenarios of fine cleaning of the fin gaps and efficient cleaning of large areas of dirt, and can be matched to different types of condenser 20 clogging. For example, in environments with a lot of dust, a straight brush head can be used. In environments with a lot of lint, a roller brush head can be used.

[0079] Please see Figure 2 According to some embodiments of this application, the condenser device 100 further includes a fan assembly 60, which is disposed on the first mounting plate 10 and located on the air outlet side of the condenser 20; wherein the fan assembly 60 includes a fan 62, which is configured to drive airflow from the air outlet side to the air inlet side during the movement of the cleaning component 40.

[0080] Specifically, the fan assembly 60 includes a fan bracket 61 and a fan 62 mounted on the fan bracket.

[0081] When the cleaning mechanism is working, the fan 62 operates synchronously and blows air, causing the airflow to flow from the air outlet side to the air inlet side of the condenser 20. The airflow passes through the gaps between the fins of the condenser 20, which can carry away the dirt cleaned by the cleaning brush. When the condenser 20 is exchanging heat normally, the fan 62 continues to operate and draw air, and the airflow flows from the air inlet side to the air outlet side of the condenser 20. The circulation of airflow on the surface of the condenser 20 can not only help improve the cleaning effect of the cleaning mechanism, but also help the condenser 20 maintain a stable heat exchange airflow environment.

[0082] According to some embodiments of this application, this application also proposes a temperature control unit, including: a compressor, an evaporator, and a condenser device 100 as described in any of the above embodiments, wherein the compressor, condenser 20, and evaporator are connected in sequence via refrigerant pipelines.

[0083] This application proposes an energy storage system, which can be an energy storage container, energy storage cabinet, energy storage power station, etc. The energy storage system can store electrical energy during off-peak hours and provide power to relevant users or electrical equipment during peak hours. The energy storage system includes a battery compartment and a temperature control unit as described in the above embodiment. The battery compartment contains battery devices, and the temperature control unit is used to regulate the temperature inside the battery compartment.

[0084] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
