[0001] This utility model relates to the field of air handling unit technology, specifically to a direct expansion type air handling unit with independent temperature and humidity control. Background Technology

[0002] In the field of modern building environmental control, direct expansion air handling units play a crucial role. Through the coordinated operation of the direct expansion refrigeration system and the humidity control system, they achieve precise regulation of indoor air temperature and humidity. However, traditional direct expansion air handling units often have the problem of excessive integrity in their structural design. Once a functional component fails, due to the close connection and interrelation between the components, maintenance personnel usually need to disassemble the entire unit and send it back to the manufacturer or a professional repair station for repair. This process is not only time-consuming and labor-intensive, but also requires a lot of human and material resources. Utility Model Content

[0003] In view of the problems existing in the current direct expansion air handling units, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a direct expansion type air handling unit with independent temperature and humidity control, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A direct-expansion type air handling unit with independent temperature and humidity control includes a base plate, a temperature control module, a humidity control module, and a ventilation module. The temperature control module, humidity control module, and ventilation module are arranged sequentially from left to right on the top of the base plate. Temperature sensors and humidity sensors are respectively installed on the top of the temperature control module and humidity control module. An air inlet is fixedly provided on one side of the temperature control module, and an air outlet is fixedly provided on one side of the ventilation module. Wedge-shaped blocks are fixedly provided on the lower sides of the temperature control module, humidity control module, and ventilation module. Wedge-shaped grooves are formed on the upper surface of the base plate at positions corresponding to the wedge-shaped blocks, and each wedge-shaped block corresponds to a wedge-shaped groove. The temperature control module and ventilation module are connected by a plug. Sealing rings are fixedly installed on the side closest to the humidity control module and on both sides of the humidity control module. Two adjacent sealing rings abut against each other. Rotating rods are rotatably installed at the four corners of the upper surface of the base plate. A rotating plate is fixedly sleeved on the upper end of the rotating rod. A U-shaped plate is fixedly installed at the end of the rotating plate away from the rotating rod. The U-shaped plate abuts against the outside of the two corresponding sealing rings. A fixed shell is fixedly installed on the lower surface of the base plate. A bidirectional lead screw is rotatably installed inside the fixed shell. Transmission mechanisms that drive multiple rotating rods to rotate are provided at both ends of the bidirectional lead screw. A drive mechanism that drives the bidirectional lead screw to rotate is provided at the bottom of the fixed shell.

[0007] Preferably, the transmission mechanism includes gears and racks, and sliding plates are slidably arranged on both sides of the interior of the fixed housing. One end of each of the two sliding plates is threadedly connected to one end of a corresponding bidirectional lead screw. Multiple gears are fixedly sleeved on the lower end of the corresponding rotating rod, and multiple racks are meshed on one side of the corresponding gears. One end of each of the multiple racks extends into the interior of the fixed housing and is fixedly connected to the corresponding sliding plate.

[0008] Preferably, the driving mechanism includes a transmission rod and a motor. The transmission rod is rotatably disposed in the lower middle part of the fixed housing and located below the bidirectional lead screw. A first bevel gear is fixedly sleeved at the middle end of the bidirectional lead screw, and a second bevel gear is fixedly sleeved at the upper end of the transmission rod. The first bevel gear and the second bevel gear are meshed and connected. The motor is fixedly disposed at the bottom of the fixed housing, and the output end of the motor is fixedly connected to one end of the transmission rod.

[0009] Preferably, each of the sealing rings has a rubber pad on its end face.

[0010] Preferably, a sliding rod is fixedly provided on the upper inner wall of the fixed shell, and one end of each of the two sliding plates is movably sleeved with the rod wall of the sliding rod.

[0011] Preferably, the motor is fixedly connected to the fixed housing via a support frame.

[0012] Preferably, dustproof nets are fixedly installed inside both the air inlet and the air outlet.

[0013] Preferably, the inner wall of the wedge groove and the outer wall of the wedge block are both coated with a wear-resistant coating.

[0014] Preferably, the temperature control module is equipped with a heater, the humidity control module is equipped with a humidifier, and the ventilation module is equipped with a fan.

[0015] Preferably, the inner wall of the U-shaped plate is provided with a rubber pad.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] This invention utilizes a motor to drive a transmission rod, which in turn drives a second bevel gear. This causes a bidirectional lead screw to move two sliding plates, which in turn move corresponding racks. The racks then drive the gears, causing multiple rotating rods to rotate. These rotating rods, in turn, drive corresponding rotating plates to rotate. This allows multiple U-shaped plates to rotate and separate from their corresponding sealing rings, thus releasing the limits between the temperature control module, humidity control module, and ventilation module. In the event of a malfunction in a module, only the faulty module needs to be disassembled and sent for repair, eliminating the need to send the entire device for maintenance. This significantly saves time and labor costs, and improves the convenience and efficiency of equipment maintenance. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a direct expansion type air handling unit with independent temperature and humidity control.

[0028] Example 1

[0029] Reference Figure 1-5A direct-expansion type air handling unit with independent temperature and humidity control includes a base plate 1, a temperature control module 2, a humidity control module 3, and a ventilation module 4. The temperature control module 2, humidity control module 3, and ventilation module 4 are arranged sequentially from left to right on top of the base plate 1. The temperature control module 2 contains a heater, the humidity control module 3 contains a humidifier, and the ventilation module 4 contains a fan, enabling effective temperature, humidity, and ventilation control. Temperature sensors 5 and humidity sensors 6 are respectively installed on the top of the temperature control module 2 and humidity control module 3. An air inlet is fixedly installed on one side of the temperature control module 2, and an air outlet is fixedly installed on one side of the ventilation module 4. Dust filters are fixedly installed inside both the air inlet and outlet to improve the dustproof performance of the unit. Wedge-shaped blocks 11 are fixedly installed on the lower sides of the temperature control module 2, humidity control module 3, and ventilation module 4. Multiple wedge-shaped blocks 11 are provided on the upper surface of the base plate 1 at positions corresponding to the upper surface of the base plate 1. The wedge-shaped groove and multiple wedge blocks 11 are inserted into the corresponding wedge-shaped groove. The inner wall of the wedge-shaped groove and the outer wall of the wedge block 11 are coated with a wear-resistant coating to improve the wear resistance of the wedge-shaped groove and the wedge block 11. The temperature control module 2 and the ventilation module 4 are fixedly provided with sealing rings 7 on the side close to the humidity control module 3 on both sides. The two adjacent sealing rings 7 abut against each other. The end face of the multiple sealing rings 7 is provided with rubber pads to improve the sealing between the two adjacent sealing rings 7. Rotating rods 8 are rotatably provided at the four corners of the upper surface of the base plate 1. Rotating plates 9 are fixedly sleeved on the upper end of the rotating rods 8. U-shaped plates 10 are fixedly provided at the end of the rotating plates 9 away from the rotating rods 8. The U-shaped plates 10 are close to the outer side of the two corresponding sealing rings 7. The inner wall of the U-shaped plates 10 is provided with rubber pads so that the U-shaped plates 10 can be stably sleeved on the outer side of the two corresponding sealing rings 7. A fixed shell 14 is fixedly provided on the lower surface of the base plate 1. A bidirectional screw 16 is rotatably provided inside the fixed shell 14.

[0030] Example 2

[0031] Reference Figure 1-5 The two ends of the bidirectional lead screw 16 are provided with a transmission mechanism that drives multiple rotating rods 8 to rotate. The transmission mechanism includes gears 12 and racks 13. Slide plates 15 are slidably arranged on both sides of the interior of the fixed shell 14. One end of each slide plate 15 is threadedly connected to one end of the corresponding bidirectional lead screw 16. Multiple gears 12 are fixedly sleeved on the lower end of the corresponding rotating rods 8. Multiple racks 13 are meshed on one side of the corresponding gears 12. One end of each rack 13 extends into the interior of the fixed shell 14 and is fixedly connected to the corresponding slide plate 15. A sliding rod 17 is fixedly arranged on the upper inner wall of the fixed shell 14. One end of each slide plate 15 is movably sleeved with the rod wall of the sliding rod 17, so that the slide plate 15 cannot rotate, that is, it can slide stably.

[0032] Example 3

[0033] Reference Figure 1-5The bottom of the fixed housing 14 is provided with a drive mechanism that drives the bidirectional lead screw 16 to rotate. The drive mechanism includes a transmission rod 19 and a motor 21. The transmission rod 19 is rotatably disposed in the lower middle part of the fixed housing 14 and located below the bidirectional lead screw 16. A first bevel gear 18 is fixedly sleeved at the middle end of the bidirectional lead screw 16, and a second bevel gear 20 is fixedly sleeved at the upper end of the transmission rod 19. The first bevel gear 18 and the second bevel gear 20 are meshed and connected. The motor 21 is fixedly disposed at the bottom of the fixed housing 14. The output end of the motor 21 is fixedly connected to one end of the transmission rod 19. The motor 21 is fixedly connected to the fixed housing 14 through a support frame, so that the connection between the motor 21 and the fixed housing 14 is more stable.

[0034] In this invention, during use, the motor 21 drives the transmission rod 19 to rotate, which in turn drives the second bevel gear 20 to rotate. This causes the bidirectional lead screw 16 to move the two sliding plates 15, which in turn move the corresponding racks 13. The racks 13 then drive the gears 12 to rotate, thereby causing multiple rotating rods 8 to rotate. The rotating rods 8 then drive the corresponding rotating plates 9 to rotate, thus enabling the multiple U-shaped plates 9 to rotate and separate from the corresponding sealing rings 7. (Because the inner wall of the U-shaped plate 9 is provided with a rubber pad, the U-shaped plate 9 can easily engage with the outer side of the sealing ring 7.) Remove the sealing ring 7 from the outside, thus releasing the limit between the temperature control module 2, humidity control module 3 and ventilation module 4. Then pull the corresponding wedge block 11 forward, so that the wedge block 11 can be pulled out from the corresponding wedge groove. This allows the temperature control module 2, humidity control module 3 and ventilation module 4 to be disassembled individually. In other words, when a module of the equipment fails, only the faulty module needs to be disassembled and sent for repair, instead of sending the entire device for repair. This greatly saves time and labor costs and improves the convenience and efficiency of equipment maintenance.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
