[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example

[0022] See Figure 1 As shown, this utility model provides an embodiment of a combined air conditioning unit with a two-stage rotary dehumidifier.

[0023] Two-stage rotary dehumidification combined air conditioning units include:

[0024] The first impeller system includes a first impeller 101, a first fan assembly, and a first temperature control assembly. The processing air passage of the first impeller 101 is used to circulate air and dehumidify the air. The regeneration air passage of the first impeller 101 is used to circulate air and dry and regenerate the first impeller 101. The first fan assembly drives air through the processing air passage and the regeneration air passage of the first impeller 101. The first temperature control assembly controls the temperature of the air entering the processing air passage and the regeneration air passage of the first impeller 101.

[0025] The second impeller system includes a second impeller 201, a second fan assembly, and a second temperature control assembly. The processing air duct of the second impeller 201 is used to circulate air and dehumidify the air. The regeneration air duct of the second impeller 201 is used to circulate air and dry and regenerate the second impeller 201. The processing air inlet pipe and the regeneration air inlet pipe of the second impeller 201 are both connected to the processing air outlet pipe of the first impeller 101. The regeneration air outlet pipe of the second impeller 201 is connected to the regeneration air inlet pipe of the first impeller 101. The second fan assembly drives air through the processing air duct and the regeneration air duct of the second impeller 201. The second temperature control assembly regulates the temperature of the air entering the processing air duct and the regeneration air duct of the second impeller 201.

[0026] The first rotor 101 and the second rotor 201 mentioned above are rotors with identical structures. Each rotor has a processing air channel and a regeneration air channel, which are not interconnected. Moist air enters the processing air channel and comes into contact with the rotor. The rotor is made of a special material that adsorbs moisture from the air. The adsorbed dry air is then sent out of the processing air channel. After adsorbing moisture, the rotor rotates to the regeneration air channel. Heated air is then blown in the opposite direction into the regeneration air channel, coming into contact with the rotor, causing the moisture to desorb and be discharged outdoors. The rotor then regains its moisture absorption capacity.

[0027] The first impeller 101 is used for pre-dehumidification and preheating / pre-cooling of fresh air. The first impeller 101 is made of a material with high moisture absorption properties. The first impeller 101 is primarily responsible for removing most of the moisture from the fresh air and, as needed, preheating or pre-cooling it to create better working conditions for the second impeller 201. The second impeller 201 is used for fine dehumidification of the air treated by the first impeller 101. The second impeller 201 is made of a material with even higher moisture absorption properties and works in conjunction with the first impeller 101 to further reduce air humidity, achieving dry air with a dew point temperature < -50℃DP, allowing for more precise humidity control as needed.

[0028] When the ambient humidity is relatively high and the humidity requirement is not particularly strict, dehumidification can be performed using only the first rotor system. In this case, humid air enters the processing air passage of the first rotor 101 through the processing air inlet pipe, is dehumidified, and is then directly discharged through the processing air outlet pipe of the first rotor 101; dry air enters the regeneration air passage of the first rotor 101 through the regeneration air inlet pipe, is regenerated by the first rotor 101, and is then discharged through the regeneration air outlet pipe of the first rotor 101.

[0029] When the ambient humidity is very low and the humidity requirements are very strict, the dual-rotor operation mode can be activated. In this mode, humid air enters the processing air passage of the first rotor 101 through the processing air inlet pipe, removing most of the moisture. Then, it enters the processing air passage of the second rotor 201 through the processing air inlet pipe for further dehumidification, and then exits the processing air passage of the second rotor 201 through the processing air outlet pipe. Simultaneously, air exiting from the processing air outlet pipe of the first rotor 101 enters the regeneration air passage of the second rotor 201 through the regeneration air inlet pipe, regenerating the second rotor 201. After regenerating the second rotor 201, it exits the regeneration air passage of the second rotor 201 through the regeneration air outlet pipe, then enters the regeneration air passage of the first rotor 101 through the regeneration air inlet pipe, regenerating the first rotor 101 before exiting through the regeneration air outlet pipe.

[0030] Air circulates between the first rotor 101 and the second rotor 201 to achieve energy recovery and utilization.

[0031] In this embodiment, the first temperature control component includes a first surface cooler 102, which is connected to the processing air inlet pipe of the first rotor.

[0032] The first surface cooler 102 regulates the temperature of the air entering the first rotor 101, and can regulate the air to normal temperature and humidity (11.0℃, 95%).

[0033] In this embodiment, the first temperature control component further includes a processing air evaporator 103 and a low-temperature water surface cooler 104, which are connected to the processing air inlet pipe of the first rotor 101.

[0034] The processing air evaporator 103 and the low-temperature water surface cooler 104 regulate the temperature of the air entering the first rotor 101. Through the interaction of the first surface cooler 102, the processing air evaporator 103, and the low-temperature water surface cooler 104, the air can be processed to a lower temperature and humidity (5°C, 95%).

[0035] In this embodiment, the first temperature control component further includes a first electric heater 105, which is connected to the regeneration air inlet pipe of the first rotor.

[0036] The first electric heater 105 raises the air temperature, removes the humidity from the first rotor 101, and regenerates the first rotor 101.

[0037] In this embodiment, the first temperature control component further includes a first regenerated air condenser 106 and a first regenerated air evaporator 107. The first regenerated air condenser 106 is connected to the regenerated air inlet pipe of the first rotor, and the first regenerated air evaporator 107 is connected to the regenerated air outlet pipe of the first rotor.

[0038] The first regenerated air evaporator 107 and the first regenerated air condenser 106 are a heat pump system. The first regenerated air condenser 106 dissipates heat to heat the air, and the first regenerated air evaporator 107 absorbs heat to cool the air.

[0039] The interaction between the first electric heater 105 and the first regenerated air evaporator 107 raises the air temperature, removes the humidity from the first rotor 101, and regenerates the first rotor 101. The first regenerated air evaporator 107 is activated (using the heat from the heat pump cycle) to cool the regenerated air, thereby achieving energy reuse and reducing energy consumption.

[0040] In this embodiment, the first fan assembly includes a first processing air fan 108 and a first regeneration air fan 109, which are respectively connected to the processing air inlet pipe of the first impeller 101 and the regeneration air outlet pipe of the first impeller 101.

[0041] In this embodiment, the second temperature control component further includes a second surface cooler 202, which is connected to the processing air inlet pipe of the second rotor 201.

[0042] The second surface cooler 202 regulates the temperature of the air before it enters the second rotor 201, which can reduce the air temperature to about 12°C and 12% humidity, so that the air can be better dehumidified when it passes through the second rotor 201, and can be treated to about 15°C and 0.2% humidity.

[0043] In this embodiment, the second temperature control component further includes a second electric heater 203, which is connected to the regeneration air inlet pipe of the second rotor.

[0044] The second electric heater 203 raises the air temperature, removes the humidity inside the second rotor 201, and regenerates the second rotor 201.

[0045] In this embodiment, the second temperature control component further includes a second regenerative air condenser 204 and a second regenerative air evaporator 205. The second regenerative air condenser 204 is connected to the regenerative air inlet pipe of the second rotor, and the second regenerative air evaporator 205 is connected to the regenerative air outlet pipe of the second rotor.

[0046] The second regenerated air evaporator 205 and the second regenerated air condenser 204 are a heat pump system. The second regenerated air condenser 204 dissipates heat to heat the air, and the second regenerated air evaporator 205 absorbs heat to cool the air.

[0047] The second electric heater 203 and the second regenerated air evaporator 205 interact to raise the air temperature and remove the humidity in the second rotor 201, thereby regenerating the second rotor 201. The second regenerated air evaporator 205 is started, and the heat from the heat pump cycle is used to cool the regenerated air, thereby achieving energy reuse and reducing energy consumption.

[0048] In this embodiment, the second fan assembly includes a second processing air fan 206 and a second regeneration air fan 207, which are respectively connected to the processing air inlet pipe and the regeneration air outlet pipe of the second rotor 201.

[0049] In this embodiment, the second impeller system further includes a filter 208, which is connected to the processing air inlet duct of the second impeller 201. By providing the filter 208, particulate matter in the processing air can be filtered, thereby protecting the second impeller 201. The filter 208 is an F8 filter. An F8 filter is a medium-efficiency filter, mainly used to filter particulate matter in the air, primarily capturing dust particles of 1-5 micrometers.

[0050] In this embodiment, the casing is made of high-strength metal material to ensure the structural stability and durability of the unit. The outer surface of the casing is covered with 50mm thick rock wool insulation material, which has good insulation performance and corrosion resistance, preventing cold bridging and the intrusion of external heat. The entire casing adopts a sealed design to ensure low air leakage, reduce energy loss, and improve efficiency. The casing material and internal structure design take into account the characteristics of high temperature and high humidity resistance to ensure normal operation in harsh environments. An intelligent control system is equipped to control the first and second rotor systems to achieve precise control of temperature and humidity. This control system can be adjusted according to actual needs to achieve optimal operating efficiency.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
