Description

Technical Field

[0001] This invention relates to the field of chiller technology, and in particular to a chiller with automatic dehumidification and temperature regulation functions. Background Technology

[0002] In existing commercial and industrial liquid-cooled energy storage cabinets or other equipment, the coolant provided by the chiller can only cool the battery pack. When the humidity inside the cabinet is high and the temperature drops, condensation easily forms, damaging the electrical equipment. The conventional solution is to install a dehumidifying air conditioner inside the cabinet. When the temperature is low, in order to maintain the ambient temperature inside the container, it is usually necessary to use a heating air conditioner or electric heating to heat the container or energy storage cabinet.

[0003] For example, application CN220065788U discloses a 30-foot energy storage container, including a container body. A battery pack module is installed on the left side of the inner wall of the container body. A temperature and humidity sensor is installed on the upper rear side of the container body. An installation assembly is provided on the upper left side of the container body. An air conditioner is installed on the upper left side of the container body through the installation assembly. An air outlet is installed on the upper left side of the container body. This utility model, using the above structure, allows for multi-faceted regulation of the temperature and humidity inside the container during use. When the temperature and humidity sensor detects a high temperature inside the container, the control module controls the ventilation mechanism, air conditioner, and dehumidifier based on the internal temperature and humidity values. This not only effectively ensures that the temperature and humidity inside the container remain within a controllable range but also effectively reduces the power consumption of the temperature and humidity control equipment.

[0004] However, the above solution requires the installation of air conditioners and dehumidifiers inside the cabinet. In this solution, the air conditioners and dehumidifiers occupy the space of the energy storage cabinet, reducing the space utilization rate inside the energy storage cabinet and increasing the cost.

[0028] Example 1:

[0029] This invention provides a chiller with automatic dehumidification and temperature control functions, such as... Figures 1-4As shown, it includes: a plate heat exchanger 1, a compressor 2, a first condenser 3, and a dehumidification module 4. The plate heat exchanger 1, compressor 2, and first condenser 3 are connected in sequence to form a first circulation loop. The first circulation loop is used for cooling or heating. The dehumidification module 4 is used for dehumidification. The dehumidification module 4 includes a second condenser 5, an exhaust fan 6, and a gas heating device 7. The second condenser 5, compressor 2, and first condenser 3 are connected in sequence to form a second circulation loop. The exhaust fan 6 is located between the second condenser 5 and the gas heating device 7, and the output end of the exhaust fan 6 faces the gas heating device 7.

[0030] Plate heat exchanger 1 is connected to return pipe 8 and supply pipe 9 respectively. Circulation pump 10 is installed on return pipe 8. Plate heat exchanger 1 is connected to the input end of first condenser 3 through first connecting pipe 11. Compressor 2 is installed on first connecting pipe 11. Output end of first condenser 3 is connected to plate heat exchanger 1 through second connecting pipe 12. First electronic expansion valve 13 and first electric valve 14 are installed on first connecting pipe 11. Fan 15 is installed on the side of first condenser 3 away from plate heat exchanger 1. Output end of fan 15 faces first condenser 3.

[0031] The input end of the second condenser 5 is connected to the second connecting pipe 12 through the third connecting pipe 16. The third connecting pipe 16 is equipped with a second electronic expansion valve 17 and a second electric valve 18. The output end of the second condenser 5 is connected to the first connecting pipe 11 through the fourth connecting pipe 19.

[0032] The working principle and beneficial effects of the above technical solution are as follows: This chiller is suitable for use in cabinets of energy storage liquid chillers, data centers, charging piles, and other equipment. The return pipe 8 connects to the equipment output end, and the supply pipe 9 connects to the equipment input end. Under the action of the circulating pump 10, the liquid flows through the return pipe 8 into the plate heat exchanger 1, then through the first connecting pipe 11, through the compressor 2, into the first condenser 3, and through the second connecting pipe 12 back into the plate heat exchanger 1. Finally, it is supplied to the equipment from the supply pipe 9. The plate heat exchanger 1, compressor 2, and first condenser 3 are sequentially connected to form the first circulation loop, and its liquid... The cooling function can lower the temperature of the high-temperature coolant at the equipment end to the required low-temperature coolant, thereby achieving the cooling function; its liquid-cooled heating function can rapidly heat the low-temperature coolant of the external equipment, raising its temperature, thereby achieving the heating function; the dehumidification module 4 includes a second condenser 5, an exhaust fan 6, and a gas heating device 7, wherein the gas heating device 7 can be a PTC electric heater. The liquid flowing out of the first condenser 3 flows into the third connecting pipe 16 through the second connecting pipe 12, and then into the second condenser 5 through the third connecting pipe 16, and then through the second condenser 5. The fourth connecting pipe 19 at the output end returns to the first connecting pipe 11. When dehumidification is required inside the energy storage cabinet, the PTC electric heater is turned off. Under the action of the exhaust fan 6, the high-temperature and humid air inside the energy storage cabinet passes through the second condenser 5. The air comes into contact with the outside of the second condenser 5, thereby lowering the dew point temperature and removing the moisture from the air passing through the second condenser 5, thus achieving the dehumidification function. During the dehumidification process, the internal ambient temperature of the energy storage cabinet is lowered. When heating is required inside the energy storage cabinet, the PTC electric heater and the exhaust fan 6 are started. The air flows towards the PTC electric heater under the action of the exhaust fan 6. The TC electric heater and PTC electric heater can heat the passing air and make the hot air flow rapidly inside the energy storage cabinet, thus realizing the function of heating the air inside the energy storage cabinet. In this invention, the chiller can realize the cooling or heating function through the first circulation loop, and can dehumidify the air inside the energy storage cabinet through the dehumidification module 4 and the second circulation loop. There is no need to install traditional dehumidifiers and air conditioners, which not only reduces costs, but also saves a lot of space inside the energy storage cabinet. It also helps the air to flow rapidly inside the energy storage cabinet, thereby improving the dehumidification efficiency and the air heating efficiency.

[0033] Example 2

[0034] Based on the above embodiment 1, as follows Figure 1 As shown, a liquid receiving tray 20 is provided below the second condenser 5, and a condensate drain pipe 21 is provided at the output end of the liquid receiving tray 20.

[0035] The working principle and beneficial effects of the above technical solution are as follows: when hot and humid air passes through the second condenser 5, the moisture in the air comes into contact with the second condenser 5 and forms condensate. The condensate then flows down the outer wall of the second condenser 5 and flows to the liquid receiving tray 20. The liquid receiving tray 20 can collect the condensate. The collected condensate is discharged to the outside of the equipment through the condensate drain pipe 21, thereby achieving the purpose of dehumidification.

[0036] Example 3

[0037] Based on Example 1 or 2, such as Figure 2 As shown, the second condenser 5 includes a condenser shell 22. An air outlet is provided on the left side of the condenser shell 22, and an air inlet is provided on the right side of the condenser shell 22. A dustproof net 23 is provided at the air inlet. A condenser tube assembly 24 is provided inside the condenser shell 22. The condenser tube assembly 24 includes several condenser tubes. The condenser tubes are S-shaped and arranged at equal intervals. Adjacent condenser tubes are interconnected. One end of the condenser tube assembly 24 is connected to the third connecting pipe 16, and the other end of the condenser tube is connected to the fourth connecting pipe 19.

[0038] The working principle and beneficial effects of the above technical solution are as follows: the air inside the energy storage cabinet can enter the condenser shell 22 through the air inlet, and then flow out from the air outlet after passing through the dustproof net 23 and the condenser tube assembly 24 in sequence, thereby completing the dehumidification of the air. By setting the dustproof net 23, dust in the air can be blocked, avoiding the problem of dust adhering to the outer wall of the condenser tube assembly 24 and affecting the working efficiency of the condenser tube assembly 24, thus improving the dehumidification effect of the second condenser 5 and extending the service life of the condenser tube assembly 24.

[0039] Example 4

[0040] Based on Example 3, such as Figure 2 , Figure 3 As shown, a flow guide block 25 is provided inside the condenser shell 22. The flow guide block 25 is located below the condenser tube assembly 24. The longitudinal cross section of the flow guide block 25 is an isosceles triangle. The height of the left and right ends of the flow guide block 25 is less than the height of the middle position of the flow guide block 25. Several flow channels 26 are provided on the upper surface of the flow guide block 25 along the length direction of the flow guide block 25. The several flow channels 26 are equally spaced. The flow channels 26 are elongated. The left and right ends of the flow channels 26 pass through the left and right sides of the flow guide block 25, respectively.

[0041] The working principle and beneficial effects of the above technical solution are as follows: After the moisture in the air is condensed by the condenser tube assembly 24, condensate is formed on the outer wall of the condenser tube. Then the condensate flows downward along the condenser tube. In order to avoid the condensate remaining at the bottom of the condenser shell 22, a guide block 25 is set on the bottom wall of the condenser shell 22. The guide block 25 has a protrusion in the middle. When the condensate falls on the guide block 25, it can be guided to flow to both sides. Under the action of the drainage groove 26, the condensate can be collected and flow and pass through the bottom of the dustproof net 23, which increases the flow speed of the condensate. This allows the condensate to be quickly discharged to the outside of the condenser shell 22, avoiding the residue of condensate and improving the dehumidification effect.

[0042] Example 5

[0043] Based on Example 4, such as Figures 2-5 As shown, automatic adjustment devices are symmetrically arranged on the left and right sides of the condenser housing 22. Each automatic adjustment device includes an electric push rod 27, which is located at the bottom of the condenser housing 22. An output shaft is located at the upper end of the electric push rod 27, extending through the bottom wall of the condenser housing 22 and into the interior of the condenser housing 22. The output shaft is slidably and sealed to the condenser housing 22 at the penetration point. The upper end of the output shaft is hinged to one end of a first connecting rod 28, and the other end of the first connecting rod 28 is hinged to a drive rod 29 near its lower end. The drive rod 29 is hinged to the first connecting rod 28 near its upper end. One end of the second connecting rod 30 is hinged, and the other end of the second connecting rod 30 is connected to the output end of the buffer assembly. Several sealing plates 31 are provided on the side of the drive rod 29 away from the condenser tube assembly 24. The sealing plates 31 are arranged at equal intervals from top to bottom. The upper end of the sealing plate 31 is rotatably connected to the inner walls of the front and rear sides of the condenser shell 22 through a rotating shaft. The sealing plate 31 is connected to the drive rod 29 through a third connecting rod 32. One end of the third connecting rod 32 is hinged to the side wall of the drive rod 29, and the other end of the third connecting rod 32 is hinged to the sealing plate 31 near the middle position.

[0044] The working principle and beneficial effects of the above technical solution are as follows: When the second condenser 5 does not need to participate in air dehumidification or air heating, if the air inlet and outlet of the condenser housing 22 are in an open state, dust inside the energy storage cabinet is easily adsorbed onto the condenser tube assembly 24 inside the condenser housing 22. Dust accumulation can easily reduce the working efficiency of the condenser tube assembly 24 and shorten its service life. To prevent dust from entering the condenser housing 22, automatic adjustment devices are symmetrically set on the left and right sides of the condenser housing 22. The automatic adjustment devices can block the air inlet and outlet when the second condenser 5 is not in operation, reducing dust inside the condenser housing 22. Specifically, when the second condenser 5 is not in dehumidification or air heating, the electric push rod 27 is in a retracted state. At this time, the sealing plate 31 is in a nearly vertical state, and the two adjacent sealing plates 31 contact each other, thereby blocking the air inlet or outlet and reducing dust entering the condenser housing 22. When the second condenser 5 participates in air heating, the electric push rod 27 is pushed upward. The output shaft drives the drive rod 29 to move via the first connecting rod 28. The drive rod 29 moves smoothly under the action of the buffer assembly. The movement of the drive rod 29 drives several third connecting rods 32 to move synchronously. The third connecting rods 32 rotate around the rotating shaft, causing the sealing plate 31 to open to a horizontal state. At this time, outside air can quickly enter the condenser shell 22. The sealing plate 31 of the air inlet remains horizontal and does not affect the air intake volume. The sealing plate 31 of the air outlet remains horizontal and does not affect the air output volume, thus improving the air heating efficiency. When the second condenser 5 participates in dehumidification... During operation, the sealing plate 31 of the air inlet remains horizontal to ensure the air intake volume, while the angle of the sealing plate 31 of the air outlet can be adjusted according to the air humidity. When the air humidity is high, in order to achieve full condensation and dehumidification, the angle between the sealing plate 31 of the air outlet and the drive rod 29 is small, reducing the air volume and allowing the air to fully contact the condenser tube assembly 24 in the condenser shell 22, thereby improving the dehumidification effect. When the air humidity is low, the angle between the sealing plate 31 of the air outlet and the drive rod 29 is large, increasing the air volume and thus improving the dehumidification efficiency.

[0045] Example 6

[0046] Based on embodiment 5, a control component is provided on the condenser housing 22. The control component includes a controller, a humidity sensor, and an angle sensor. The controller is located outside the condenser housing 22, and the humidity sensor is located at the air inlet of the condenser housing 22. The humidity sensor is used to detect the actual humidity of the air entering the condenser housing 22. The angle sensor is located on the rotating shaft and is used to detect the angle between the sealing plate 31 and the drive rod 29. The controller is electrically connected to the humidity sensor, the angle sensor, and the electric push rod 27. The controller controls the electric push rod 27 to work based on the detection values ​​of the humidity sensor and the angle sensor.

[0047] The working principle and beneficial effects of the above technical solution are as follows: The control component can automatically adjust the angle of the sealing plate 31. When the second condenser 5 is not involved in dehumidification or air heating, the detection value of the angle sensor is close to 0°, and the angle between the sealing plate 31 and the drive rod 29 is determined by the thickness of the sealing plate 31. At this time, the upper and lower adjacent sealing plates 31 are in contact with each other, the sealing plate 31 is close to a vertical state, and both the air inlet and the air outlet are in a sealed state. When the second condenser 5 is involved in air heating, the controller controls the electric push rod 27 to extend. When the angle sensor detects 90°, the controller controls the electric push rod 27 to stop moving. At this time, the sealing plate 31 is in a horizontal state, and the sealing plate 31 and the drive rod 29 are in a sealed state. The included angle of 9 is 90°, and the air intake and exhaust volumes are kept at the maximum level. When the second condenser 5 participates in dehumidification, the sealing plate 31 at the air inlet is in a horizontal state. The included angle between the sealing plate 31 at the air outlet and the drive rod 29 is determined by the detection value of the humidity sensor. The higher the humidity, the smaller the included angle between the sealing plate 31 at the air outlet and the drive rod 29, thereby slowing down the air outflow and allowing the air to fully contact the condenser tube assembly 24. The lower the humidity, the larger the included angle between the sealing plate 31 at the air outlet and the drive rod 29, thereby improving the dehumidification efficiency. The included angle between the sealing plate 31 and the drive rod 29 is greater than the preset minimum angle and less than or equal to 90°. The preset minimum angle is the angle of the sealing plate 31 when the air outlet is in a sealed state.

[0048] More preferably, the controller calculates the target angle between the air vent sealing plate 31 and the drive rod 29 based on the following formula:

[0049] α X =α1+(γ1-γ2)·θ

[0050] Where, α X α is the target angle between the air outlet sealing plate 31 and the drive rod 29. X The maximum angle is no more than 90°. α1 is the preset angle of the sealing plate 31, which is 45°. δ1 is the preset average humidity of the air inside the condenser shell 22, which is calculated from multiple test results. δ2 is the actual humidity of the air inside the condenser shell 22 detected by the humidity sensor. θ is the angle change, which can be set according to actual needs. θ is preferably 15°.

[0051] After the calculation is completed, the controller can control the electric push rod 27 to move according to the target angle between the air outlet sealing plate 31 and the drive rod 29. When the detection value of the angle sensor is equal to the target angle between the air outlet sealing plate 31 and the drive rod 29, the controller controls the electric push rod 27 to stop moving. At this time, the sealing plate 31 is held at the target angle position, which can achieve sufficient dehumidification of the air, improve the dehumidification effect of the second condenser 5, ensure dehumidification efficiency, and realize the automatic adjustment of the angle of the sealing plate 31, thus improving the degree of automation.

[0054] The working principle and beneficial effects of the above technical solution are as follows: When the drive rod 29 moves upward, the drive rod 29 can drive the sliding column 39 to move upward through the second connecting rod 30. The upward movement of the sliding column 39 drives the squeezing block 34 to slide upward through the limiting plate 40. The buffer spring 35 is compressed. The elastic force of the buffer spring 35 can make the movement of the drive rod 29 more stable and improve the reliability of the drive rod 29. At the same time, external air can enter the cleaning tank 33 through the air inlet pipe 37 and be stored below the squeezing block 34. When the drive rod 29 moves downward, under the action of the buffer spring 35, the squeezing block 34 slides downward, so that the air below the squeezing block 34 is discharged from the exhaust pipe 38. The discharged air can blow towards the outside of the dustproof net 23, thereby achieving the effect of dust removal from the dustproof net 23 and avoiding the dustproof net 23 from being blocked and affecting the air intake efficiency. At the same time, the blown air can also blow towards the bottom of the condenser shell 22, accelerating the outflow of condensate.

[0055] Example 8

[0056] Based on Example 7, such as Figure 5 As shown, a diversion pipe 41 is provided at the lower end of the exhaust pipe 38. The diversion pipe 41 is connected to the exhaust pipe 38 and is perpendicular to the exhaust pipe 38. The diversion pipe 41 is located between the dustproof net 23 and the drive rod 29. Several air outlets are provided on the bottom wall of the diversion pipe 41. A spray head 42 is provided at the air outlet. The output end of the spray head 42 faces the outer wall of the dustproof net 23.

[0057] The working principle and beneficial effects of the above technical solution are as follows: The diversion pipe 41 is long and narrow. The diversion pipe 41 can divert the air flowing out of the exhaust pipe 38 and discharge it from multiple spray heads 42, making the sprayed air more dispersed, expanding the blowing area of ​​the dust screen 23, improving the cleaning effect of the dust screen 23, and further increasing the outflow speed of condensate water, achieving rapid dehumidification and enhancing the dehumidification effect of the second condenser 5.
