Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The following is for reference. Figures 1-6 An air conditioner 100 according to an embodiment of the present invention is described.

[0041] An air conditioner 100 according to an embodiment of the present invention includes: a rotary dehumidifier 1 and a heat exchanger 2, wherein the air conditioner 100 operates according to the control method of the air conditioner 100 described above.

[0042] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the rotary dehumidifier 1 includes a housing 11 and a rotor 12. The space inside the housing 11 is divided into a mutually isolated processing zone 111 and a regeneration zone 112. Airflow flows through the processing zone 111. The rotor 12 is rotatably disposed inside the housing 11 and is divided into a generating section 121 and a regeneration section 122. Along the airflow direction, the rotary dehumidifier 1 is located upstream of the heat exchanger 2.

[0043] Understandably, the impeller 12 has good moisture absorption properties, used to absorb moisture from the airflow, ensuring dehumidification. The portion of the impeller 12 located in the processing zone 111 comes into contact with the airflow, forming the generating section 121 after absorbing moisture from the airflow. The portion of the impeller 12 located in the regeneration zone 112 does not come into contact with the airflow; the impeller 12 forms the regeneration section 122 after removing water through heating or other methods. The heat exchanger 2 is used for heat exchange with the airflow, and the temperature of the airflow can be adjusted by regulating the surface temperature of the heat exchanger 2. When the airflow enters the air conditioner 100, such as... Figure 6 The AD process shown first involves passing the airflow through the rotor 12 in the processing zone 111 to adjust the humidity, and then... Figure 6 The DE process shown in the diagram involves adjusting the airflow temperature via heat exchanger 2, thereby enabling independent regulation of airflow humidity and temperature. This allows for more precise control of the temperature and humidity of the air supplied by the air conditioner 100 to meet the user's air supply requirements and improve the comfort of the air conditioner 100.

[0044] In existing technology, when an air conditioner is in cooling and dehumidification mode, such as Figure 6 The AC process shown lowers the surface temperature of the heat exchanger below the dew point temperature of the airflow, causing water to precipitate out and thus achieving dehumidification. The airflow is then reheated.Figure 6 The C-B process shown makes the air flow rise to a comfortable temperature. This will cause the condensed water to adhere to the surface of the heat exchanger for a long time to produce mold and odor, affecting the air conditioner air supply quality, and when the air conditioner is applied to a vehicle, the generation of condensed water is also easy to cause safety risks, thereby affecting the driving safety of the vehicle. In addition, the mode of the air conditioner first deeply cooling and dehumidifying the air flow and then heating will greatly increase the energy consumption of the air conditioner.

[0045] In the present application, the moisture in the air flow is adsorbed by the rotary dehumidification device 1, and then cooled by the heat exchanger 2, and at the same time, the control method of the air conditioner 100 described above can effectively avoid the generation of condensed water on the surface of the heat exchanger 2, so that mold can be avoided on the surface of the heat exchanger 2 and odor can be avoided in the air flow, thereby improving the air supply quality of the air conditioner 100. When the air conditioner 100 is applied to a vehicle, the air conditioner 100 on the vehicle will not produce water dripping phenomenon, thereby improving the driving safety of the vehicle. In addition, the air conditioner 100 meets the comfort air supply requirement, and breaks the mode of the traditional air conditioner 100 first deeply cooling and dehumidifying the air flow and then heating, which can effectively reduce the energy consumption of the air conditioner 100, and has the effect of energy saving.

[0046] According to the air conditioner 100 of the embodiment of the present application, the rotary dehumidification device 1 and the heat exchanger 2 located downstream are arranged in the air conditioner 100, the space in the shell 11 of the rotary dehumidification device 1 is divided into a treatment area 111 and a regeneration area 112 which are isolated from each other, and the rotary wheel 12 is rotatably arranged in the shell 11 and is divided into an occurrence part 121 and a regeneration part 122, which can ensure the dehumidification effect and realize independent adjustment of the humidity and temperature of the air flow to meet the air supply requirement of the user, thereby improving the comfort of the air conditioner 100. The air flow flowing to the heat exchanger 2 can also avoid generating condensed water on the surface of the heat exchanger 2, which can improve the air supply quality of the air conditioner 100, and at the same time, can reduce the energy consumption of the air conditioner 100 to achieve the effect of energy saving. When the air conditioner 100 is applied to a vehicle, the driving safety of the vehicle can be improved.

[0047] In some embodiments of the present application, the rotary dehumidification device 1 further comprises a heater arranged in the regeneration area 112 for heating the rotary wheel 12 to release moisture. The occurrence part 121 rotating into the regeneration area 112 can release moisture through the heating of the heater, so as to be converted into the regeneration part 122 to be rotated into the treatment area 111 again to realize dehumidification. In this way, the conversion between the occurrence part 121 and the regeneration part 122 can be realized, thereby realizing the repeated circulation of the rotary wheel 12.

[0048] In some embodiments of the present application, the rotating wheel 12 is a solid CaCl2 piece. The solid CaCl2 piece has stable performance and strong moisture absorption capacity. The rotating wheel 12 only needs to absorb and release moisture to realize recycling, which can ensure the stability of the dehumidification of the rotating wheel dehumidification device 1. In addition, compared with the liquid absorption dehumidification device, the solid CaCl2 dehumidification rotating wheel 12 has no loss of liquid carrying by flying liquid, does not need to supplement the moisture absorbent, and will not corrode other metal parts, which can greatly reduce the maintenance cost.

[0049] In some embodiments of the present application, as shown in Figure 2 The air conditioner 100 further comprises a cabinet 3, a first sensor 4 and a second sensor 5. The rotating wheel dehumidification device 1 and the heat exchanger 2 are arranged in the cabinet 3. The cabinet 3 is provided with an air inlet 31, and the air inlet 31 is communicated with the processing area 111. The first sensor 4 is arranged at the air inlet 31 and used for detecting the temperature and humidity of the airflow entering the rotating wheel dehumidification device 1. The shell 11 is provided with an air vent, and the second sensor 5 is arranged at the air vent and used for detecting the temperature and humidity of the airflow flowing to the heat exchanger 2. By arranging the first sensor 4 and the second sensor 5 at the air inlet 31 and the air vent respectively, the temperature and humidity of the airflow entering the rotating wheel dehumidification device 1 and the temperature and humidity of the airflow flowing to the heat exchanger 2 can be detected in real time. Thus, the temperature and humidity signals can be transmitted to the processor, so that the processor can judge and send a control signal to the controller, and finally the supply air temperature and humidity can be adjusted. The temperature and humidity adjustment accuracy of the air conditioner 100 corresponding to different working conditions can be improved, thereby improving the comfort and experience of the user.

[0050] In some embodiments of the present application, as shown in Figure 2 The air conditioner 100 further comprises a blower 6. The blower 6 is arranged in the cabinet 3 and is arranged downstream of the heat exchanger 2 in the airflow flow direction. The cabinet 3 is provided with an air outlet 32, and the blower 6 is used for driving the airflow to flow from the air inlet 31 to the air outlet 32. By arranging the blower 6, power can be provided for the airflow flowing into and out of the air conditioner 100, so as to ensure the circulation of the airflow in the air conditioner 100, thereby achieving the purpose of adjusting the temperature and humidity of the airflow in the air conditioner 100.

[0051] The control method of the air conditioner 100 according to the embodiments of the present application is described below.

[0052] As shown in Figure 1 The control method of the air conditioner 100 according to the embodiments of the present application comprises:

[0053] It is determined that the air conditioner 100 is started in the cooling and dehumidification mode;

[0054] At least part of the regeneration part 122 is controlled to be located in the processing area 111;

[0055] The surface temperature T0 of the heat exchanger 2 and the dew point temperature T1 of the air flow flowing to the heat exchanger 2 are obtained.

[0056] The angle a of the regeneration part 122 located in the processing area 111 is adjusted according to the surface temperature T0 of the heat exchanger 2 and the dew point temperature T1 of the air flow flowing to the heat exchanger 2.

[0057] In the present application, the air conditioner 100 can be provided with a processor and a remote controller, the processor is in communication connection with the remote controller, and the user can select different operation modes through the buttons on the remote controller, for example, when the user selects the cooling mode button and the dehumidification mode button on the remote controller, the processor will receive the signal from the remote controller, thereby determining to start the cooling and dehumidification mode.

[0058] Preferably, the air conditioner 100 can also be provided with a voice sensor for receiving the voice instruction of the user, and the processor is in communication connection with the voice sensor, for example, the user can directly convey the need for cooling and dehumidification mode through voice, and the voice sensor will send a signal to the processor, thereby determining to start the cooling and dehumidification mode.

[0059] Further, the air conditioner 100 is provided with a controller, the controller is in communication connection with the processor, and the processor can obtain the operation mode of the air conditioner 100 required by the user through the remote controller or the voice sensor, and transmit a signal to the controller, and the controller sends a control signal to control the runner 12 and the heat exchanger 2 respectively, thereby adjusting the supply air temperature and humidity of the air conditioner 100.

[0060] When the user selects the cooling and dehumidification mode through the remote controller or voice, the processor will send the parsed signal to the controller after receiving the instruction of the air conditioner 100 starting the cooling and dehumidification mode, and the controller will control the runner 12 to rotate according to the received signal, so that the regeneration part 122 rotates into the processing area 111 to adsorb the moisture of the air flow, and at the same time, the surface temperature of the heat exchanger 2 is adjusted, so that the heat exchanger 2 absorbs the heat of the air flow when the air flow flows through, thereby achieving the purpose of cooling and dehumidification.

[0061] The air conditioner 100 may be equipped with a temperature sensor and a second sensor 5. The temperature sensor is used to detect the surface temperature T0 of the heat exchanger 2, and the second sensor 5 is used to detect the temperature and humidity of the airflow flowing to the heat exchanger 2. The temperature sensor and the second sensor 5 are respectively connected to the processor. The temperature sensor and the second sensor 5 transmit the measured temperature signals to the processor. The processor calculates the dew point temperature T1 of the airflow flowing to the heat exchanger 2 based on the obtained temperature and humidity of the airflow flowing to the heat exchanger 2. Then, it compares T1 and T0, and then sends a control signal to the controller based on the comparison result, so that the controller controls the rotor 12 to rotate and adjusts the angle α of the regeneration section 122 located in the processing zone 111. Thus, the dehumidification capacity of the rotor dehumidification device 1 can be adjusted according to the specific situation. In this way, the dew point temperature T1 of the airflow flowing to the heat exchanger 2 can be actively controlled to be less than or equal to the surface temperature T0 of the heat exchanger 2, thereby avoiding the formation of condensation on the surface of the heat exchanger 2.

[0062] In existing technology, when an air conditioner is in cooling and dehumidification mode, such as Figure 6 The AC process shown lowers the surface temperature of the heat exchanger below the dew point temperature of the airflow, causing water to precipitate out and thus achieving dehumidification. The airflow is then reheated. Figure 6 The CB process shown causes the airflow to rise to a comfortable temperature. This can lead to condensation adhering to the heat exchanger surface for extended periods, resulting in mold and odors, affecting the air conditioner's airflow quality. When used in vehicles, this condensation can also pose safety risks, impacting driving safety. Furthermore, the air conditioner's method of first deeply cooling and dehumidifying the airflow before reheating significantly increases its energy consumption.

[0063] In this application, the dehumidifier 1 absorbs moisture from the airflow, which is then cooled by the heat exchanger 2. Simultaneously, the control method of the air conditioner 100 described above effectively prevents condensation on the surface of the heat exchanger 2, thus avoiding mold growth and unpleasant odors. This improves the airflow quality of the air conditioner 100. When the air conditioner 100 is used in a vehicle, it will not drip water, thereby enhancing driving safety. Furthermore, while meeting the requirements for comfortable airflow, the air conditioner 100 breaks away from the traditional method of deep cooling and dehumidifying the airflow before heating, effectively reducing energy consumption and achieving energy-saving effects.

[0064] According to the control method of the air conditioner 100, the air flow humidity and temperature can be independently adjusted by arranging the rotary dehumidification device 1 and the heat exchanger 2 in the air conditioner 100, so as to meet the air supply requirements of the user. When the air conditioner 100 is started in the cooling and dehumidification mode, at least part of the regeneration part 122 is located in the processing area 111, and the angle α of the regeneration part 122 located in the processing area 111 is adjusted according to the surface temperature T0 of the heat exchanger 2 and the dew point temperature T1 of the air flow flowing to the heat exchanger 2. Thus, the dehumidification amount of the rotary dehumidification device 1 can be adjusted according to the specific conditions of the air flow and the heat exchanger 2, so as to avoid the condensate water generated on the surface of the heat exchanger 2 by the air flow flowing to the heat exchanger 2, improve the air supply quality of the air conditioner 100, reduce the energy consumption of the air conditioner 100, and achieve the energy saving effect. When the air conditioner 100 is applied to a vehicle, the driving safety of the vehicle can be improved.

[0065] In some embodiments of the present application, as shown in Figures 1-4 adjusting the angle α of the regeneration part 122 located in the processing area 111 according to the surface temperature T0 of the heat exchanger 2 and the dew point temperature T1 of the air flow flowing to the heat exchanger 2 includes:

[0066] determining that the surface temperature T0 of the heat exchanger 2 is less than the dew point temperature T1 of the air flow flowing to the heat exchanger 2;

[0067] controlling the angle α of the regeneration part 122 located in the processing area 111 to increase.

[0068] It can be understood that the processor obtains the dew point temperature T1 of the air flow flowing to the heat exchanger 2 according to the temperature and humidity of the air flow flowing to the heat exchanger 2, and then compares T1 and T0. When the processor determines that T0 < T1, the heat exchanger 2 has the risk of condensation at this time, the processor sends a control signal to the controller, and the controller controls the rotation of the rotary wheel 12, so that the angle α of the regeneration part 122 located in the processing area 111 increases, that is, a larger area of the regeneration part 122 is in contact with the air flow in the processing area 111, so as to increase the dehumidification amount of the rotary dehumidification device 1, that is, the A-D-E process shown in Figure 6 is changed into an A-D'-E' process, so as to increase the dew point temperature T1 of the air flow flowing to the heat exchanger 2.

[0069] In this way, the dew point temperature T1 of the air flow flowing to the heat exchanger 2 can be actively controlled to be less than or equal to the surface temperature T0 of the heat exchanger 2, so as to avoid the condensate water generated on the surface of the heat exchanger 2 by the air flow flowing to the heat exchanger 2. Further, the air supply quality of the air conditioner 100 can be improved, the energy consumption of the air conditioner 100 can be reduced, and the energy saving effect can be achieved. When the air conditioner 100 is applied to a vehicle, the driving safety of the vehicle can be improved.

[0070] In some embodiments of the present application, as shown in Figures 1-4As shown, the control method of the air conditioner 100 further comprises:

[0071] determining that the surface temperature T0 of the heat exchanger 2 is less than the dew point temperature T1 of the air flow flowing to the heat exchanger 2 and that the regeneration part 122 is entirely located in the processing area 111;

[0072] controlling the surface temperature T0 of the heat exchanger 2 to rise.

[0073] It can be understood that when the regeneration part 122 is entirely located in the processing area 111, at this time the rotary dehumidification device 1 has reached the maximum dehumidification amount, if the processor determines that the surface temperature T0 of the heat exchanger 2 is still less than the dew point temperature T1 of the air flow flowing to the heat exchanger 2 at this time, the processor sends a control signal to the controller, so that the controller controls the surface temperature T0 of the heat exchanger 2 to rise, so that the dew point temperature T1 of the air flow flowing to the heat exchanger 2 is less than or equal to the surface temperature T0 of the heat exchanger 2, so that the air flow flowing to the heat exchanger 2 can be prevented from producing condensate water on the surface of the heat exchanger 2. Further, the air supply quality of the air conditioner 100 can be improved, and the energy consumption of the air conditioner 100 can be reduced to achieve energy saving effect. When the air conditioner 100 is applied to a vehicle, the driving safety of the vehicle can be improved.

[0074] In some embodiments of the present application, as shown in Figure 1 and Figure 2 adjusting the angle α of the regeneration part 122 located in the processing area 111 according to the surface temperature T0 of the heat exchanger 2 and the dew point temperature T1 of the air flow flowing to the heat exchanger 2 further comprises:

[0075] determining that the surface temperature T0 of the heat exchanger 2 is greater than or equal to the dew point temperature T1 of the air flow flowing to the heat exchanger 2;

[0076] obtaining the set air outlet temperature T2 and air outlet humidity h1 of the air conditioner 100, the temperature T3 of the air flow flowing to the heat exchanger 2, and the humidity h2 of the air flow entering the rotary dehumidification device 1;

[0077] adjusting the angle α of the regeneration part 122 located in the processing area 111 according to the set air outlet humidity h1 of the air conditioner 100 and the humidity h2 of the air flow entering the rotary dehumidification device 1, and controlling the surface temperature T0 of the heat exchanger 2 according to the set air outlet temperature T2 of the air conditioner 100 and the temperature T3 of the air flow flowing to the heat exchanger 2.

[0078] It can be understood that the processor obtains the dew point temperature T1 of the air flow flowing to the heat exchanger 2 according to the temperature and humidity of the air flow flowing to the heat exchanger 2, and then compares T1 and T0. When the processor determines that T0≥T1, the heat exchanger 2 has no risk of condensation at this time. Then the processor sends a control signal to the controller according to the user-set air outlet humidity h1 and the humidity h2 of the air flow entering the rotary dehumidifying device 1, so that the controller controls the rotation of the rotary wheel 12 to adjust the angle α of the regeneration part 122 located in the processing area 111, so that the air flow is reduced to the target humidity. Then the processor sends a control signal to the controller according to the user-set air outlet temperature T2 and the temperature T3 of the air flow flowing to the heat exchanger 2, so that the controller controls the heat exchanger 2 to adjust the surface temperature T0, so that the air flow is reduced to the target temperature.

[0079] In this way, the humidity and temperature of the air flow can be independently adjusted, so that the temperature and humidity of the air supply of the air conditioner 100 are more accurately controlled to meet the air supply requirements of the user and improve the comfort of the air conditioner 100.

[0080] It should be noted that the air conditioner 100 can be provided with a first sensor 4 for detecting the temperature and humidity of the air flow entering the rotary dehumidifying device 1. The first sensor 4 is in communication connection with the processor, and the first sensor 4 transmits the measured temperature and humidity signal to the processor, and the processor makes a judgment to transmit a control signal to the controller.

[0081] In some embodiments of the present application, as shown in Figure 1 and Figure 2 、 Figure 4 and Figure 5 adjusting the angle α of the regeneration part 122 located in the processing area 111 according to the air outlet humidity h1 set by the air conditioner 100 and the humidity h2 of the air flow entering the rotary dehumidifying device 1 includes:

[0082] According to the difference a between the air outlet humidity h1 set by the air conditioner 100 and the humidity h2 of the air flow entering the rotary dehumidifying device 1, the angle α of the regeneration part 122 located in the processing area 111 is adjusted. The greater the difference a, the greater the angle α of the regeneration part 122 located in the processing area 111. The smaller the difference a, the smaller the angle α of the regeneration part 122 located in the processing area 111.

[0083] The greater the humidity difference a is, the greater the dehumidification amount of the rotary dehumidifying device 1 is required, and at this time, the processor sends a control signal to the controller, so that the controller controls the angle a of the regenerating part 122 located in the processing area 111 to increase, that is, a larger area of the regenerating part 122 is in contact with the airflow in the processing area 111, so that the dehumidification amount can be increased. Conversely, the smaller the humidity difference a is, the smaller the dehumidification amount of the rotary dehumidifying device 1 is required, and at this time, the processor sends a control signal to the controller, so that the controller controls the angle a of the regenerating part 122 located in the processing area 111 to decrease, that is, a smaller area of the regenerating part 122 is in contact with the airflow in the processing area 111, so that the dehumidification amount can be decreased. In this way, the dehumidification amount of the rotary dehumidifying device 1 can be adjusted by controlling the rotation angle of the rotary wheel 12, so that the supply air humidity of the air conditioner 100 can be accurately controlled to meet the user's supply air requirements.

[0084] It should be noted that the angle of the generating part 121 located in the processing area 111 is φ, Figure 5 The linear graph shown is the linear relationship between the wet load of the rotary wheel 12, that is, the dehumidification amount, and the angle φ of the generating part 121 located in the processing area 111. The wet load of the rotary wheel 12 is inversely proportional to the angle φ of the generating part 121 located in the processing area 111, and is proportional to the angle a of the regenerating part 122 located in the processing area 111.

[0085] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The control method of the air conditioner 100 further comprises:

[0086] Determining that the air conditioner 100 is in a dehumidification without temperature reduction mode;

[0087] Obtaining the set supply air humidity h1 of the air conditioner 100 and the humidity h2 of the airflow entering the rotary dehumidifying device 1;

[0088] Adjusting the angle a of the regenerating part 122 located in the processing area 111 according to the set supply air humidity h1 of the air conditioner 100 and the humidity h2 of the airflow entering the rotary dehumidifying device 1, and the heat exchanger 2 is not working.

[0089] The air conditioner 100 is in a dehumidification without temperature reduction mode, so the temperature of the airflow does not need to be changed, and therefore the heat exchanger 2 is not working. The processor sends a control signal to the controller according to the obtained set supply air humidity h1 of the air conditioner 100 and the humidity h2 of the airflow entering the rotary dehumidifying device 1, so that the controller controls the rotary wheel 12 to rotate to adjust the angle a of the regenerating part 122 located in the processing area 111, so that the airflow is reduced to the target humidity. The supply air humidity of the air conditioner 100 can be accurately controlled to meet the user's supply air requirements, thereby improving the comfort of the air conditioner 100.

[0090] In some embodiments of the present application, as shown in Figure 1 andFigure 2 As shown, the control method of the air conditioner 100 further comprises:

[0091] determining that the air conditioner 100 starts the cooling and non-dehumidification mode;

[0092] obtaining the outlet air temperature T2 set by the air conditioner 100 and the temperature T3 of the airflow flowing to the heat exchanger 2;

[0093] controlling the angle α of the regenerative part 122 located in the processing area 111 to be 0°, and adjusting the surface temperature of the heat exchanger 2 according to the outlet air temperature T2 set by the air conditioner 100 and the temperature T3 of the airflow flowing to the heat exchanger 2.

[0094] When the air conditioner 100 starts the cooling and non-dehumidification mode, the humidity of the airflow does not need to be changed, so the angle α of the regenerative part 122 located in the processing area 111 is controlled to be 0°, and the airflow flowing through the processing area 111 only contacts the generating part 121. The processor sends a control signal to the controller according to the outlet air temperature T2 set by the user and the temperature T3 of the airflow flowing to the heat exchanger 2, so that the controller controls the heat exchanger 2 to adjust the surface temperature T0, thereby reducing the airflow to the target temperature. In this way, the supply air temperature of the air conditioner 100 can be accurately controlled to meet the user's supply air requirements, thereby improving the comfort of the air conditioner 100.

[0095] The vehicle according to the embodiment of the present application comprises the air conditioner 100 described above.

[0096] The vehicle according to the embodiment of the present application, by arranging the rotary dehumidification device 1 and the heat exchanger 2 located downstream in the air conditioner 100, the space in the shell 11 of the rotary dehumidification device 1 is divided into the processing area 111 and the regeneration area 112 which are isolated from each other, and the rotary wheel 12 is rotatably arranged in the shell 11 and is divided into the generating part 121 and the regenerative part 122, which can ensure the dehumidification effect and realize independent adjustment of the humidity and temperature of the airflow, thereby improving the comfort of the air conditioner 100. It can also avoid the condensate water generated on the surface of the heat exchanger 2 by the airflow flowing to the heat exchanger 2, improve the supply air quality of the air conditioner 100, and reduce the energy consumption of the air conditioner 100 to achieve energy saving effect. When the air conditioner 100 is applied to a vehicle, the driving safety of the vehicle can be improved.
