A reverse-flow indirect evaporative cooling chiller unit based on the Internet of Things

Abstract

This invention discloses a reverse-flow indirect evaporative cooling chiller unit based on the Internet of Things (IoT), relating to the field of evaporative cooling technology. It includes a mounting base with a mounting housing fixedly connected to its upper side. A descaling mechanism is fixedly installed inside the mounting housing. This invention uses a temperature sensor at the cooling air terminal connected to a control panel. When the temperature difference between the actual sensor reading and the adjusted temperature is abnormal, an ultrasonic generator produces ultrasonic waves, and a motor drives a rolling wheel to rotate synchronously. Because the locking wheel, coupling shaft, and ring sleeve form a rotating component, derailment of the rotating descaling assembly is prevented. The four rotating components are engaged with the inner and outer walls of the annular track. Driven by the rolling wheel, the rotating descaling assembly rolls around the annular track, thereby driving the ultrasonic generator to produce ultrasonic waves over a wider range. This also avoids fixed ultrasonic wave positions and the existence of descaling dead zones, thus preventing a reduction in the heat exchange efficiency of the heat transfer tubes and ensuring stable unit operation.

Description

Technical Field

[0001] This invention relates to the field of evaporative cooling technology, specifically to a reverse-flow indirect evaporative cooling chiller unit based on the Internet of Things. Background Technology

[0002] Indirect evaporative cooling cools by absorbing heat through the evaporation of water. It can only achieve good cooling effects when the air used has a large difference between the dry and wet bulb temperatures. Evaporative cooling technology is mainly used in evaporative cooling air conditioning units that produce cold air and evaporative cooling water chillers that produce cold water.

[0003] In existing technologies, such as the "Reverse Flow Indirect Evaporative Cooling Chiller Unit" with Chinese Patent No. CN106403112A, a water distribution system and exhaust fan are installed at the top of the indirect evaporative cooler, and a water tank is installed at the bottom. Inside the unit's casing, air first enters the dry channel of the indirect evaporative cooler from the air inlet side, flows downwards from the bottom surface, then turns 180° and flows back into the wet channel of the indirect evaporative cooler from the bottom surface, flowing upwards from the water spray surface and then being discharged outdoors by the exhaust fan. Circulating water is sprayed from the water distribution system to the water spray surface, enters the wet channel of the indirect evaporative cooler, flows out from the bottom surface, flows into the water tank, and is supplied to the user end. In the wet channel, the circulating water flows downwards in the opposite direction to the humid air, and the temperature of the humid air it comes into contact with gradually decreases, so the temperature of the circulating water also gradually decreases until it exits the wet channel, where its temperature can approach the dew point temperature of the outdoor air. Furthermore, this unit only requires one fan system, has low energy consumption, and a simple structure.

[0004] However, in existing technologies, indirect evaporative cooling chillers are devices that produce high-temperature chilled water to provide cooling energy to indoor air conditioning terminals. They are energy-efficient and do not produce condensate at the indoor air conditioning terminals, resulting in better indoor hygiene, hence their widespread use. However, some problems have arisen during their application. Currently, most indirect evaporative cooling chiller systems are open systems. When the circulating water comes into contact with air, it carries away dust from the air. This dust accumulates on the air conditioning terminal components, causing blockages. Furthermore, the combination of water and dust can come into contact with the condenser or evaporator, adhering to the heat transfer tubes. The high oxygen content in the water can corrode the heat transfer tubes, and some impurities in the dust are complex, easily forming scale on the surface of the heat transfer tubes. Scale reduces the thermal conductivity of the heat transfer tubes, significantly reducing the cooling effect. To achieve the desired cooling effect, the unit's operating time and efficiency must be increased, leading to increased energy consumption. Summary of the Invention

[0005] The purpose of this invention is to provide an IoT-based reverse-flow indirect evaporative cooling chiller unit to address the aforementioned issues. Indirect evaporative cooling chillers are devices that produce high-temperature chilled water to provide cooling energy to indoor air conditioning terminals. They are energy-efficient and produce no condensate at the indoor air conditioning terminals, resulting in better indoor hygiene and thus widespread application. However, some problems have arisen during their application. Currently, most indirect evaporative cooling chiller units have open water systems. When circulating water comes into contact with air, it carries away dust from the air. This dust accumulates on the air conditioning terminal components, causing blockages. Furthermore, the combination of water and dust can come into contact with the condenser or evaporator, adhering to the heat transfer tubes. The high oxygen content in the water can corrode the heat transfer tubes, and the complex impurities in the dust can easily form scale on the surface of the heat transfer tubes. Scale reduces the thermal conductivity of the heat transfer tubes, significantly diminishing the cooling effect. To achieve the desired cooling effect, the unit's operating time and efficiency must be increased, leading to increased energy consumption.

[0006] This invention achieves pre-cooling of indoor hot air, improving cooling efficiency, shortening time, reducing energy consumption, and performing ultrasonic descaling on the heat transfer tubes in the condenser, improving the heat conduction efficiency of the heat transfer tubes and maintaining a high-efficiency cooling effect. At the same time, it avoids the dead zones in descaling caused by fixed ultrasonic positions, thereby preventing a reduction in the heat exchange effect of the heat transfer tubes and ensuring stable operation of the unit. In addition, it can perform spray cooling on the condenser, cool the flowing gas, and increase the humidity of the air, thereby increasing the continuous working time of the condenser and ensuring the stable operation of all parts of the unit.

[0017] Compared with existing technologies, the advantages of this system are:

[0018] 1. In this invention, by setting up a descaling mechanism, ultrasonic descaling of the heat transfer tubes in the condenser is achieved, improving the heat conduction efficiency of the heat transfer tubes and maintaining a high-efficiency cooling effect. By setting a temperature sensor at the end of the cold air and connecting it to the control panel, when the temperature difference between the actual temperature sensor and the adjusted temperature is abnormal, the ultrasonic generator works to generate ultrasonic waves. Then the motor starts, driving the drive gear to rotate, and the meshing driven gear gets power, thereby driving the rolling wheel to rotate synchronously. Since the locking wheel, connecting shaft and ring sleeve are combined to form a rotating component, the double-layer drop of the annular track makes the rotating components form a locking relationship, which restricts the descaling component from derailing. The four rotating components are locked on the inner and outer walls of the annular track. Driven by the rolling wheel, the rotating descaling component rolls around the annular track, thereby driving the ultrasonic generator to generate ultrasonic waves over a wider range. At the same time, it also avoids the ultrasonic wave position being fixed and there being dead corners in descaling, thereby avoiding the heat exchange effect of the heat transfer tubes being reduced and ensuring the stable operation of the unit.

[0019] 2. In this invention, by setting a pre-cooling mechanism, the indoor hot air is pre-cooled, improving cooling efficiency, shortening time, and reducing energy consumption. By starting the servo motor, the turbine rotates, and the turbine generates suction in its center, causing the indoor hot air to pass through the arc-shaped air inlet and the turbine to reach the upper part of the mounting box. Driven by the overall airflow, the indoor hot air is divided into several parts by the inner flow channel. The outside low-temperature fresh air passes through the outer flow channel under the directional blowing of the cooling fan mechanism. The outside low-temperature fresh air is also divided into several parts. The heat-conducting particles absorb the heat in the indoor hot air and transfer it to the heat dissipation film. The heat dissipation film evenly disperses the heat. The outside low-temperature fresh air carries the heat in the heat-conducting particles and is released from the cooling fan mechanism. Thus, the indoor hot air is pre-cooled, the hot air temperature is reduced, and the efficiency of subsequent cooling is improved.

[0020] 3. In this invention, by setting up a water cooling mechanism, spray cooling of the condenser is achieved, while cooling of the flowing gas and increasing air humidity are also achieved. By connecting the water storage tank to an external water source and starting a small pressurizing pump, the water in the water storage tank is pressurized and transported from the connecting water pipe to the dispersion pipe. The water is then released from several atomizing nozzles on each branch of the dispersion pipe, and the resulting water mist falls on the condenser, providing cooling protection for the condenser. The air carries the remaining water mist, absorbing heat from the air and increasing air humidity, thereby increasing the continuous working time of the condenser and ensuring the stable operation of all parts of the unit.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Reference Figure 1-8As shown: A reverse-flow indirect evaporative cooling chiller unit based on the Internet of Things includes a mounting base 1, a mounting housing 4 fixedly connected to the upper side of the mounting base 1, a descaling mechanism 9 fixedly installed inside the mounting housing 4, the descaling mechanism 9 including a rotary descaling component 91, the rotary descaling component 91 including an ultrasonic generator 9110, a fixing cover 919 fixedly connected to one side of the ultrasonic generator 9110, a sector block 914 fixedly connected to the other side of the fixing cover 919, a motor 917 fixedly installed inside the fixing cover 919, a drive gear 918 fixedly installed at the upper end of the motor 917, and the drive gear 918... The outer side of 18 overlaps with the inner side of the fixed cover 919. A driven gear 916 overlaps inside the sector block 914. A rolling wheel 915 is fixedly installed in the middle of the driven gear 916. The outer surface of the rolling wheel 915 is rotatably connected to the inner side of the sector block 914. The outer side of the driven gear 916 meshes with the outer side of the driving gear 918. A connecting shaft 912 is fixedly connected to the other side of the sector block 914. A locking wheel 911 is rotatably connected to the left end of the outer surface of the connecting shaft 912. A ring sleeve 913 is rotatably connected to the middle of the outer surface of the connecting shaft 912. The left side of the ring sleeve 913 overlaps with the right side of the locking wheel 911. The right side of the ring 911 overlaps with the left side of the sector block 914. A ring track 92 is slidably engaged with the outer side of the locking wheel 911. The outer surface of the ring sleeve 913 slidably engages with the outer surface of the ring track 92. A support frame 93 is fixedly connected to the left side of the ring track 92, and a fixing angle plate 94 is fixedly connected to the lower side of the support frame 93. By installing a temperature sensor at the end of the cold air unit and connecting it to the control panel, when the temperature difference between the actual temperature sensor and the adjusted temperature is abnormal, the ultrasonic generator 9110 generates ultrasonic waves. Then, the motor 917 starts, driving the drive gear 918 to rotate, and the meshing driven gear 916 receives power. The force drives the rolling wheel 915 to rotate synchronously. Since the locking wheel 911, the connecting shaft 912 and the ring sleeve 913 are combined to form a rotating component, the double-layer drop of the annular track 92 makes the rotating components form a locking relationship, which restricts the descaling component 91 from derailing. The four rotating components are locked on the inner and outer walls of the annular track 92. Driven by the rolling wheel 915, the rotating descaling component 91 rolls around the annular track 92, thereby driving the ultrasonic generator 9110 to generate ultrasonic waves over a wider range. At the same time, it also avoids the ultrasonic waves from being fixed in position and creating descaling dead zones, thereby avoiding a reduction in the heat exchange effect of the heat transfer tube and ensuring the stable operation of the unit.

[0047] according to Figure 1 As shown, a cooling fan mechanism 3 is fixedly installed on the upper left side of the mounting box 4, and an air exchange hole 2 is fixedly installed on the lower left side of the mounting box 4. An indoor air outlet mechanism 5 is fixedly connected to the upper middle part of the mounting box 4. When the cooling fan mechanism 3 is activated, it drives the air flow in the leftmost part of the mounting box 4. Here, the low-temperature fresh air from the outside exchanges heat with the hot air from the indoor air outlet mechanism 5 to achieve pre-heating.

[0048] according to Figure 2 As shown, a preheating mechanism 6 is fixedly connected to the middle left end of the mounting box 4. A gathering plate 7 is fixedly installed on the lower middle part of the mounting box 4 and on the right side near the preheating mechanism 6. A compressor 8 is fixedly installed above the gathering plate 7. A descaling mechanism 9 is fixed parallel to the right side near the gathering plate 7. A condenser 10 is provided on the right side of the descaling mechanism 9 and fixed inside the mounting box 4. After the indoor hot air exchanges heat and dissipates heat through the preheating mechanism 6, it passes through the gathering plate 7, the descaling mechanism 9 and the condenser 10 and is cooled at the evaporator 13.

[0049] according to Figure 2 As shown, a water cooling mechanism 11 is fixedly connected to the lower side of the condenser 10. An evaporator 13 is provided to the right of the water cooling mechanism 11 and is fixed inside the mounting box 4. An indoor air inlet 14 is fixedly installed at the right end of the inside of the mounting box 4. A connecting pipe 12 is fixedly connected to the outer wall of the compressor 8. The compressor 8, condenser 10 and evaporator 13 are connected to each other in sequence through the connecting pipe 12. Air passes through the condenser 10, and the water cooling mechanism 11 cools the air while cooling the condenser 10. During the whole process, the compressor 8 circulates the refrigerant to ensure that the condenser 10 and the water cooling mechanism 11 work normally. Finally, the cooled air is discharged back into the room from the indoor air inlet 14.

[0050] according to Figure 3 As shown, the indoor air outlet mechanism 5 includes a turbine 53. An arc-shaped air inlet 52 is fixedly installed on the upper side of the turbine 53. An upper connecting plate 51 is fixedly connected to the lower side of the arc-shaped air inlet 52. Connecting columns 54 are fixedly connected to the four corners of the lower side of the upper connecting plate 51. A cross-shaped lower connecting plate 55 is fixedly connected to the lower side of the connecting column 54. A servo motor 56 is fixedly connected to the lower side of the cross-shaped lower connecting plate 55. The rotating shaft end of the servo motor 56 is fixedly connected to the middle of the turbine 53. When the servo motor 56 is started, it drives the turbine 53 to rotate. The rotation of the turbine 53 generates suction in its middle, causing the indoor hot air to pass through the arc-shaped air inlet 52 and the turbine 53 and reach the upper part of the mounting box 4.

[0051] according to Figure 4 As shown, the cooling fan mechanism 3 includes a fan blade assembly 33. A drive motor 35 is fixedly installed in the middle of the fan blade assembly 33. A fixed plate frame 34 is fixedly connected to the lower side of the drive motor 35. An annular shell 32 is fixedly connected to the left outer periphery of the fixed plate frame 34. A protective fence 31 is fixedly connected to the left side of the annular shell 32. When the drive motor 35 is started, the fan blade assembly 33 rotates mechanically to generate wind force. In conjunction with the annular shell 32, it accelerates the directional flow of air. The fixed plate frame 34 plays a supporting role.

[0052] according to Figure 5As shown, the preheating mechanism 6 includes an inner flow channel 61, a heat exchange plate assembly 62 is fixedly connected to the front side of the inner flow channel 61, and an outer flow channel 63 is fixedly connected to the front side of the heat exchange plate assembly 62. Driven by the overall airflow, the indoor hot air is divided into several parts by the inner flow channel 61, and the outside low-temperature fresh air passes through the outer flow channel 63 under the directional blowing of the cooling fan mechanism 3. The outside low-temperature fresh air is also divided into several parts, and heat exchange occurs in this process.

[0053] according to Figure 6 As shown, the heat exchanger assembly 62 includes a heat dissipation film 622, with heat-conducting particles 623 uniformly fixedly connected to the middle of the heat dissipation film 622. Insulation plates a621 and b624 are fixedly connected to both sides of the heat dissipation film 622, respectively. The two ends of the heat-conducting particles 623 are embedded in the interior of the insulation plates a621 and b624, respectively. The heat-conducting particles 623 absorb heat from the indoor hot air and transfer it to the heat dissipation film 622. The heat dissipation film 622 evenly disperses the heat. The low-temperature fresh air from the outside carries the heat from the heat-conducting particles 623 and releases it from the cooling fan mechanism 3, thereby pre-cooling the indoor hot air, reducing the hot air temperature, and improving the efficiency of subsequent cooling.

[0054] according to Figure 7 As shown, the condenser 10 includes a heat transfer tube 103. Heat exchange plates 102 are uniformly fixedly connected to the outer surface of the heat transfer tube 103. A fixed outer frame 101 is fixedly connected to both ends of the heat exchange plates 102. An input end 104 is fixedly connected to the left side of the heat transfer tube 103, and an output end 105 is fixedly connected to the right side of the same side of the heat transfer tube 103. The refrigerant changes from a gaseous state to a liquid state in the heat transfer tube 103. The released heat is transferred to the external heat exchange plates 102 through the heat transfer tube 103. Several heat exchange plates 102 disperse the heat, and the liquefied refrigerant is transported to the evaporator 13.

[0055] according to Figure 8 As shown, the water cooling mechanism 11 includes a receiving box 115. A water storage tank 113 is fixedly connected to the inner wall of the receiving box 115. A small pressure pump 114 is fixedly installed on the bottom surface of the inner cavity of the water storage tank 113. A dispersion pipe 111 is fixedly connected to the upper side of the water storage tank 113. A connecting water pipe 112 is fixedly connected to the middle of the top of the dispersion pipe 111. The lower end of the connecting water pipe 112 is fixedly connected to the outside of the small pressure pump 114. By connecting the water storage tank 113 to an external water source and starting the small pressure pump 114, the water in the water storage tank 113 is pressurized and transported from the connecting water pipe 112 to the dispersion pipe 111. The water is released from several atomizing nozzles 116 on each branch of the dispersion pipe 111. The water mist formed falls on the condenser 10, providing a cooling protection for the condenser 10. The air carries the remaining water mist to circulate, absorbing heat from the air and increasing the humidity of the air, thereby increasing the continuous working time of the condenser 10 and ensuring the stable operation of all parts of the unit.

[0056] The usage and working principle of this device are as follows: First, the servo motor 56 is started, driving the turbine 53 to rotate. The rotation of the turbine 53 generates suction in its center, causing the indoor hot air to pass through the arc-shaped air inlet 52 and the turbine 53 to reach the upper part of the mounting box 4. Driven by the overall airflow, the indoor hot air is divided into several parts by the inner flow channel 61. The outside low-temperature fresh air, under the directional blowing of the cooling fan mechanism 3, passes through the outer flow channel 63. The outside low-temperature fresh air is also divided into several parts. The heat-conducting particles 623 absorb the heat from the indoor hot air and transfer it to the heat dissipation film 622. The heat dissipation film 622 evenly disperses the heat. The outside low-temperature fresh air, carrying the heat from the heat-conducting particles 623, is released from the cooling fan mechanism 3.

[0057] After the indoor hot air exchanges heat through the preheating mechanism 6, it passes through the gathering plate 7, the descaling mechanism 9, and the condenser 10, and then reaches the water cooling mechanism 11. The water storage tank 113 is connected to an external water source. The small pressurizing pump 114 is started to pressurize the water in the water storage tank 113 and deliver it to the dispersing pipe 111 through the connecting water pipe 112. The water is released from several atomizing nozzles 116 on each branch of the dispersing pipe 111, and the water mist formed falls on the condenser 10 to provide cooling protection for the condenser 10. The air carries the remaining water mist to circulate, absorbing heat from the air and increasing the humidity of the air. Cooling is completed at the evaporator 13, and the cooled air is discharged back into the room through the indoor air inlet 14.

[0058] A temperature sensor is installed at the cold air terminal and connected to the control panel. When the temperature difference between the actual temperature sensor and the adjusted temperature is abnormal, the ultrasonic generator 9110 works to generate ultrasonic waves. Then, the motor 917 starts, driving the drive gear 918 to rotate. The meshing driven gear 916 gets power, thereby driving the rolling wheel 915 to rotate synchronously. Since the locking wheel 911, the connecting shaft 912 and the ring sleeve 913 are combined to form a rotating component, the double-layer drop of the annular track 92 makes the rotating components form a locking relationship, which restricts the descaling component 91 from derailing. The four rotating components are locked in the inner and outer walls of the annular track 92. Driven by the rolling wheel 915, the rotating descaling component 91 rolls around the annular track 92, thereby driving the ultrasonic generator 9110 to generate ultrasonic waves over a wider range, while also avoiding the ultrasonic waves from being fixed in position and creating descaling dead zones.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
