Description
Technical Field
[0001] This utility model relates to the field of chiller technology, and in particular to an energy-saving chiller that can quickly switch cooling modes. Background Technology
[0002] A chiller unit (also known as a refrigeration unit, chiller, ice water unit, or cooling equipment) is a refrigeration device. In the refrigeration industry, it is divided into two types: air-cooled chiller units and water-cooled chiller units. Based on the compressor, it is further divided into screw chiller units, scroll chiller units, and centrifugal chiller units. In terms of temperature control, it is divided into low-temperature industrial chillers and normal-temperature chillers. The temperature of normal-temperature units is generally controlled within the range of 0℃ to 35℃, while the temperature of low-temperature units is generally controlled within the range of 0℃ to -100℃.
[0003] In existing technologies, as chiller units operate, scale tends to accumulate inside the pipes over time, increasing energy consumption. Currently, two common cleaning methods are chemical cleaning with descaling agents and physical cleaning with flexible shaft brushes. However, these methods have the following drawbacks in actual use: chemical cleaning, which involves circulation and immersion, is time-consuming; and physical cleaning, which requires inserting and cleaning with flexible shaft brushes, is difficult and inconvenient if the pipes are disassembled, increasing the user's workload. Utility Model Content
[0004] Therefore, it is necessary to provide an energy-saving chiller unit that can quickly switch cooling modes to address the problems of long time consumption and inconvenient operation when cleaning chiller unit pipes.
[0005] An energy-saving chiller unit capable of quickly switching cooling modes includes a chiller unit body and several conduits for conveying media; it also includes a cleaning mechanism, which is a set and is located inside the conduits; wherein, the cleaning mechanism includes two horizontal bars, each horizontal bar having a protrusion that contacts the inner wall of the conduit, and the horizontal bar having a collection chamber for collecting impurities inside.
[0006] In one embodiment, the cleaning mechanism further includes a spiral blade assembly, the spiral blade assembly having a T-shaped shaft inside, and the crossbar being installed at the end of the T-shaped shaft. The impact force generated when the medium flows is used in conjunction with the spiral blade assembly to drive the cleaning mechanism.
[0007] In one embodiment, the interior of the horizontal bar is provided with a guide groove, the cross-section of which is L-shaped and communicates with the collection bin.
[0008] In one embodiment, a set of equally spaced guide strips are provided on the outer side of the protrusion to guide the medium and ensure the collection effect of impurities.
[0009] In one embodiment, one end of the crossbar has an opening that communicates with the impurity collection bin, and a filter plate is installed in the opening to form a media flow channel and to intercept impurities.
[0010] In one embodiment, the conduit includes a straight tube and a bend, with the end of the straight tube and the bend being detachably connected to facilitate subsequent disassembly and maintenance of the crossbar.
[0011] In one embodiment, the catheter is provided with a support rod inside, and one end of the T-shaped shaft passes through and is rotatably connected to the outside of the support rod to support the T-shaped shaft.
[0012] In one embodiment, the protrusion is made of rubber, and reinforcing ribs are embedded inside the protrusion to ensure the structural strength of the protrusion and reduce deformation.
[0013] Beneficial effects
[0014] 1. By setting up convex strips and a collection bin, the inner wall of the duct can be repeatedly scraped during the operation of the chiller unit. Combined with the collection bin, impurities are collected, thereby reducing the occurrence of dirt accumulation at the source.
[0015] 2. By setting up a spiral blade assembly and a T-shaped shaft, the flow of the medium inside the conduit causes the spiral blade assembly to drive the T-shaped shaft to move, automatically completing the dirt cleaning operation, reducing the user's cleaning time and workload.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] The following is combined Figures 1-5 This invention describes an energy-saving chiller unit with a rapidly switchable cooling mode.
[0026] In one embodiment, an energy-saving chiller unit capable of quickly switching cooling modes includes a chiller unit body 100 and several conduits 200 for conveying media; it also includes a cleaning mechanism 300, the number of which is a set, and the cleaning mechanism 300 is disposed inside the conduit 200; wherein, the cleaning mechanism 300 includes two horizontal bars 310, the horizontal bars 310 are provided with protrusions 311 that contact the inner wall of the conduit 200, and the horizontal bars 310 are provided with a collection bin 312 inside.
[0027] like Figure 2 As shown, the cleaning mechanism 300 also includes a spiral blade assembly 320, and a T-shaped shaft 321 is provided inside the spiral blade assembly 320, with a crossbar 310 installed at the end of the T-shaped shaft 321.
[0028] In this embodiment, during the flow of the medium, the impact force generated will drive the spiral blade assembly 320 and the T-shaped shaft 321 to move. Subsequently, the crossbar 310 and the convex bar 311 are driven. The convex bar 311 contacts the inner wall of the conduit 200. During the movement, the medium and impurities in contact with the convex bar 311 are guided into the impurity collection bin 312 to complete the collection of impurities, reduce the occurrence of dirt accumulation and formation, thereby reducing equipment energy consumption and making it more energy-efficient.
[0029] It should be noted that the location and number of cleaning mechanisms 300 can be determined according to actual usage requirements. The lengths of the horizontal bars 310 and the convex bars 311 can be selected according to the medium driving capacity of the chiller unit body 100 during operation and the rotation of the spiral blade assembly 320, ensuring that the spiral blade assembly 320 can drive the horizontal bars 310 to move normally during the medium flow process.
[0030] The protrusion 311 makes contact with the inner wall of the conduit 200, which solves the problem of impurity pushing and reduces the formation of dirt accumulation. The rotation speed of the T-shaped shaft 321 is only related to the cleaning frequency of the protrusion 311. Therefore, the centrifugal force generated during the movement of the horizontal bar 310 is slight.
[0031] The spiral blade assembly 320 includes a main shaft and a set of fan blades. The main shaft is tapered at the end near the medium source to reduce resistance.
[0032] This cleaning method can be used alone, where users can periodically clean the impurities in the collection bin 312. It can also be used in conjunction with chemical cleaning methods. Since there is no accumulation of dirt, the difficulty of impurity removal is reduced, which greatly reduces the amount of chemical cleaning agent to be used and the number of cycles, thereby reducing the cleaning time. Furthermore, the impurities in the collection bin 312 can be decomposed by chemical agents, realizing automated impurity removal. Apart from the addition of chemical agents, no manual intervention is required, making it more convenient. The above two methods can be selected according to actual usage needs.
[0033] like Figure 3 As shown, a guide groove 316 is provided inside the horizontal bar 310. The cross-section of the guide groove 316 is L-shaped and it is connected to the collection bin 312.
[0034] An L-shaped guide channel 316 is used to guide impurities, which, together with the impurity collection bin 312, forms a maze-like path to reduce the occurrence of impurity backflow and ensure the impurity removal effect.
[0035] It should be noted that the corners formed by the horizontal bar 310 and the guide groove 316 are all chamfered to improve the guiding effect of impurities and media.
[0036] like Figure 3 As shown, a set of guide strips 313 arranged at equal intervals are provided on the outer side of the protrusion 311.
[0037] By using the guide bar 313, the medium located between the crossbar 310 and the inner wall of the conduit 200 can be guided into the guide groove 316 to treat the impurities attached to the medium.
[0038] like Figure 5 As shown, one end of the horizontal bar 310 has an opening that communicates with the collection bin 312, and a filter plate 314 is installed inside the opening.
[0039] Impurities are collected in a concentrated manner using the collection bin 312 and then filtered by the filter plate 314 without affecting the normal flow of the medium.
[0040] It should be noted that when the convex strip 311 moves, the medium flows against it, and most of the medium will move along the direction of the guide groove 316. The guide groove 316 and the impurity collection bin 312 are both located in the middle of the horizontal strip 310. The end face of the horizontal strip 310 is solid, so when the medium and impurities enter the guide groove 316, the end face of the horizontal strip 310 will contact the outer medium, which is not easy to cause an impact and guide effect on the impurities in the guide groove 316. Moreover, due to the setting of the opening, a medium flow channel is formed between the guide groove 316 and the opening. The medium and impurities entering the guide groove 316 will move along the medium flow channel to complete the normal guide and collection of impurities.
[0041] like Figure 1 As shown, the conduit 200 includes a straight tube and a bend, and the end of the straight tube and the bend are detachably connected.
[0042] Users can periodically disassemble the straight pipe and the bend head to remove the horizontal bar 310 inside the straight pipe and clean the impurities in the collection bin 312.
[0043] like Figure 2 As shown, a support rod is provided inside the conduit 200, and one end of the T-shaped shaft 321 passes through and is rotatably connected to the outside of the support rod.
[0044] With the T-shaped shaft 321, after the spiral blade assembly 320 rotates, the crossbar 310 can be driven to move through the T-shaped shaft 321 to complete the subsequent impurity scraping operation.
[0045] like Figure 3 As shown, the material of the protrusion 311 is rubber, and the interior of the protrusion 311 is embedded with reinforcing ribs 315.
[0046] The rubber material is designed to minimize damage to the inner wall of the conduit 200 when in contact with it. The reinforcing ribs 315 ensure the structural strength of the protrusions 311 and reduce excessive deformation, thereby enhancing the scraping effect on the inner wall of the conduit 200.
[0047] Working principle: Based on the impurity production situation and the length of the conduit 200, the user selects the corresponding points and the corresponding number of cleaning mechanisms 300 for installation. When the chiller unit 100 is running, the medium will flow in the conduit 200. Subsequently, the spiral blade assembly 320 drives the crossbar 310 to move, causing the convex strip 311 to scrape off the impurities on the inner wall of the conduit 200, reducing the occurrence of dirt formation. With the help of the guide strip 313, the medium and impurities are introduced into the impurity collection chamber 312. With the help of the filter plate 314, the impurities are intercepted, and the impurity collection chamber 312 collects the impurities. The user can stop the machine for maintenance periodically, disassemble the conduit 200 and the filter plate 314 in sequence, and then empty the impurities in the impurity collection chamber 312.
[0048] It should be noted that the specific model of the chiller unit 100 mentioned above is McQuay WGZ480B, which can switch between water-cooled chilled water and hot water source through valve switching, thus completing the rapid switching of cooling mode.
[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
