Technical Field
[0001] This utility model relates to the field of dehumidification equipment technology, specifically a low-temperature heat pump regenerative rotary dehumidification system. Background Technology
[0002] Low-temperature regenerative rotary dehumidifier systems are a technology specifically designed to effectively remove moisture from the air at low temperatures. Traditional low-temperature regenerative rotary dehumidifier systems typically include an evaporator to process the air and a condenser for regeneration heating. However, this approach is prone to thermal imbalance, where excessive condensation heat is used for regeneration heating, making it difficult to balance the overall system temperature and making regeneration temperature difficult to regulate.
[0003] Furthermore, when the dehumidification rotor is working, it is usually driven by the rotation of the timing belt and timing pulley. However, if the timing pulley and timing belt age after the dehumidification rotor has been working for a long time, it is very easy for the dehumidification rotor to fail to rotate properly and perform the dehumidification step. Therefore, we propose a low-temperature heat pump regenerative rotor dehumidification system. Utility Model Content

[0007] Furthermore, the regenerative air module includes a regenerative fan, an auxiliary regenerative electric heater, and a condenser.

The air outlet end of the regenerative air intake evaporator is delivered to the dehumidification rotor for processing through the condenser and the auxiliary regenerative electric heater. The air outlet end of the dehumidification rotor is output through the regenerative fan. The auxiliary regenerative electric heater is used to additionally heat the air inside the processing air module, and the condenser heats the air.
[0008] Furthermore, it also includes a gas-liquid separator, a refrigeration compressor, an oil separator, a dryer filter, a first electronic expansion valve, and a second electronic expansion valve.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4 This utility model provides a technical solution: a low-temperature heat pump regenerative dehumidification system, including a dehumidification rotor 1, a processing air module 2, a regeneration air module 3, and a mounting frame 5. The processing air module 2 is used to cooperate with the dehumidification rotor 1 to deliver dry air. The regeneration air module 3 is used to deliver heated regeneration air to the dehumidification rotor 1 for discharge. The regeneration air module 3 includes a regeneration air inlet evaporator 4, which is used to regulate the regeneration temperature. The dehumidification rotor 1 is fixedly installed on the mounting frame 5, and the mounting frame 5 is provided with an anti-slip mechanism 6 to prevent the dehumidification rotor 1 from sliding.
[0020] The system includes a processing air module 2 that works in conjunction with the dehumidifying impeller 1 to deliver dry air, and a regeneration air module 3 that delivers heated regeneration air to the dehumidifying impeller 1 for discharge. The regeneration air module 3 also includes a regeneration air inlet evaporator 4, which first cools the air before it is heated by the regeneration air module 3. This configuration helps to regulate the regeneration temperature, balance excess condensation heat, and achieve thermal balance in the heat pump system. Furthermore, the anti-slip mechanism 6 prevents slippage caused by component aging and deformation due to prolonged operation of the dehumidifying impeller 1.
[0021] Please see Figure 1 The processing air module 2 includes a processing air evaporator 7 and a blower 8. The processing air evaporator 7 is used to cool and dehumidify the processing air, and the blower 8 is used to deliver dry air. One end of the processing air evaporator 7 is connected to one end of the dehumidification wheel 1, and one end of the dehumidification wheel 1 is connected to the blower 8.
[0022] The processing air evaporator 7 can cool and dehumidify the air that needs to be processed, and then the dehumidification wheel 1 can process it before the dry air is sent out by the blower 8.
[0023] Please see Figure 1 The regenerated air module 3 includes a regenerated fan 9, an auxiliary regenerated electric heater 10, and a condenser 11. The regenerated air intake is connected to the intake end of the regenerated air intake evaporator 4. The exhaust end of the regenerated air intake evaporator 4 is delivered to the dehumidification impeller 1 for processing via the condenser 11 and the auxiliary regenerated electric heater 10. The exhaust end of the dehumidification impeller 1 is output via the regenerated fan 9. The auxiliary regenerated electric heater 10 is used to additionally heat the air inside the processing air module 2. The condenser 11 heats the air. The module also includes a gas-liquid separator 22, a refrigeration compressor 23, an oil separator 24, a dryer filter 25, a first electronic expansion valve 26, and a second electric... The gas-liquid separator 22 is connected to the processing air evaporator 7 at one end and to the input of the refrigeration compressor 23 at the other end. The output of the refrigeration compressor 23 is connected to the oil separator 24 and to the condenser 11 at the output. A dryer filter 25 is provided between the condenser 11 and the first electronic expansion valve 26. The other end of the first electronic expansion valve 26 is connected to the input of the processing air evaporator 7. The second electronic expansion valve 27 is connected to the condenser 11 at one end and to the inlet of the regeneration air evaporator 4 at the other end.
[0024] The regenerated air is first guided to the regenerated air evaporator 4 for cooling, and then heated by the condenser 11. If the regeneration temperature still does not meet the requirements, the auxiliary regeneration electric heater 10 will be activated to further heat the air. Finally, the heated regenerated air passes through the dehumidifying impeller 1 to help restore its moisture absorption capacity and is discharged by the regeneration fan 9. During unit operation, the amount of refrigerant entering the regenerated air evaporator 4 can be controlled by adjusting the opening of the second electronic expansion valve 26, thereby adjusting the regeneration temperature. This ensures the thermal balance of the entire system even under different operating conditions, making full use of the condensing heat generated by the refrigeration compressor 23. The gas-liquid separator 22 separates the gas-liquid mixture of refrigerant flowing out of the processing air evaporator 7, ensuring that only the gaseous refrigerant returns to the refrigeration compressor 23, preventing liquid from being trapped. The refrigerant entering the refrigeration compressor 23 can cause damage. The refrigeration compressor 23 compresses the refrigerant, turning it into a high-temperature, high-pressure gas that provides the driving force for the entire refrigeration cycle. The oil separator 24 separates lubricating oil from the high-temperature, high-pressure refrigerant gas, preventing the lubricating oil from entering subsequent components with the refrigerant, thus affecting system efficiency or causing malfunctions. The dryer filter 25 removes moisture and impurities from the refrigerant, preventing blockage and corrosion. The first electronic expansion valve 27 reduces the pressure of the high-pressure liquid refrigerant by throttling, adjusting the amount of refrigerant flowing into the processing air evaporator 7 to control the temperature and humidity during the air handling process. The second electronic expansion valve 26 opens when the regeneration temperature needs to be adjusted, allowing a portion of the refrigerant to pass through and enter the regeneration air inlet evaporator 4, achieving pre-cooling of the regeneration air inlet, and the regeneration temperature can be precisely controlled by adjusting its opening degree.
[0025] Please see Figures 1-4 A drive motor 14 is fixedly mounted on one end of the mounting bracket 5. A second synchronous pulley 15 is fixedly connected to the output end of the drive motor 14. A dehumidifying wheel 1 is rotatably connected to the mounting bracket 5. A first synchronous pulley 12 is fixedly mounted on the outside of the dehumidifying wheel 1. A synchronous belt 16 is provided on the outside of the first synchronous pulley 12 and the second synchronous pulley 15.
[0026] When the dehumidifying wheel 1 needs to rotate, the drive motor 14 works, and the drive motor 14 drives the second synchronous pulley 15 to rotate. The rotating second synchronous pulley 15 can then use the synchronous belt 16 and the first synchronous pulley 12 to drive the dehumidifying wheel 1 to rotate along the mounting frame 5.
[0027] Please see Figures 1-4The anti-slip mechanism 6 includes a fixing block 13, a rotating shaft 17, a tensioning plate 18, a third synchronous pulley 19, a connecting seat 20, and a tension spring 21. The fixing block 13 is fixedly installed on the mounting frame 5. One side of the fixing block 13 is rotatably connected to the tensioning plate 18 through the rotating shaft 17. One end of the tensioning plate 18 is rotatably connected to the third synchronous pulley 19, which is in contact with the outside of the synchronous belt 16. The connecting seat 20 is fixedly installed on the mounting frame 5. The tensioning plate 18 and the connecting seat 20 are connected by the tension spring 21.
[0028] The third synchronous pulley 19 is in external contact with the synchronous belt 16, and the tension plate 18 used to install the third synchronous pulley 19 is rotatably connected to the fixing block 13 and the rotating shaft 17. Subsequently, the tension spring 21 ensures that the third synchronous pulley 19 can always be in close contact with the synchronous belt 16 for support, preventing the synchronous belt 16 from aging and loosening after long-term use, and ensuring that the dehumidifying wheel 1 can rotate normally without slippage.
[0029] In operation, the processing air module 2 works in conjunction with the dehumidifying impeller 1 to deliver dry air. The regeneration air module 3 delivers heated regeneration air to the dehumidifying impeller 1 for discharge. The regeneration air module 3 also includes a regeneration inlet evaporator 4, which first cools the air before heating it through the regeneration air module 3. This configuration regulates the regeneration temperature, balancing excess condensation heat and ensuring thermal equilibrium in the heat pump system. The anti-slip mechanism 6 prevents slippage caused by component aging and deformation during prolonged operation of the dehumidifying impeller 1. The processing air evaporator 7 cools and dehumidifies the air to be processed. After processing by the dehumidifying impeller 1, the air is delivered dry by the blower 8. The regeneration air is first guided to the regeneration inlet evaporator 4 for cooling, then heated by the condenser 11. If the regeneration temperature still does not meet the requirements, the auxiliary regeneration electric heater 10 is activated to further heat the air. Finally, the heated regenerated air passes through the dehumidifying impeller 1 to help restore its moisture absorption capacity and is discharged by the regeneration fan 9. During unit operation, the amount of refrigerant entering the regeneration air inlet evaporator 4 can be controlled by adjusting the opening of the second electronic expansion valve 26, thereby adjusting the regeneration temperature. In this way, the thermal balance of the entire system can be ensured even under different working conditions. When the dehumidifying impeller 1 needs to rotate, the drive motor 14 works, driving the second synchronous pulley 15 to rotate. The rotating second synchronous pulley 15 can then use the synchronous belt 16 and the first synchronous pulley 12 to drive the dehumidifying impeller 1 to rotate along the mounting bracket 5. The third synchronous pulley 19 is in contact with the outside of the synchronous belt 16. The middle position of the tension plate 18 used to install the third synchronous pulley 19 is rotatably connected to the fixing block 13 and the rotating shaft 17. Subsequently, the tension spring 21 ensures that the third synchronous pulley 19 can always be in close contact with the synchronous belt 16 for support, preventing the synchronous belt 16 from aging and loosening after long-term use, ensuring that the dehumidifying impeller 1 can rotate normally without slippage.
