For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Reference below Figure 1-Figure 6 An air conditioner 100 according to an embodiment of the present invention is described.

[0041] The air conditioner 100 according to the embodiment of the present invention comprises: a rotary dehumidification device 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, 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 processing area 111 and a regeneration area 112 which are isolated from each other. The airflow flows in the processing area 111. The rotor 12 is rotatably disposed in the housing 11. The rotor 12 is divided into a generating part 121 and a regenerating part 122. The rotary dehumidifier 1 is located upstream of the heat exchanger 2 along the airflow direction.

[0043] It is understandable that the rotor 12 has good hygroscopic properties and is used to absorb moisture in the airflow to ensure a dehumidification effect. The portion of the rotor 12 located in the treatment area 111 will come into contact with the airflow, and the rotor 12 will absorb moisture in the airflow to form a generating portion 121. The portion of the rotor 12 located in the regeneration area 112 will not come into contact with the airflow, and the rotor 12 will separate water by heating and other means to form a regeneration portion 122. The heat exchanger 2 is used to exchange heat with the airflow, and the temperature of the airflow can be adjusted by adjusting the surface temperature of the heat exchanger 2. When the airflow enters the air conditioner 100, as shown in FIG. Figure 6 In the AD process shown, the airflow first passes through the rotating wheel 12 in the treatment area 111 to adjust the humidity of the airflow, and then Figure 6 The DE process shown adjusts the temperature of the air flow through the heat exchanger 2, thereby forming independent regulation of the humidity and temperature of the air flow, and can more accurately control the temperature and humidity of the air supplied by the air conditioner 100 to meet the user's air supply requirements, thereby improving the comfort of the air conditioner 100.

[0044] In the prior art, when the air conditioner is in the cooling and dehumidification mode, Figure 6 The AC process shown in the figure will reduce the surface temperature of the heat exchanger to below the dew point temperature of the airflow, so that the water in the airflow is separated out to achieve the purpose of dehumidification, and then heat the airflow, such as Figure 6 The CB process shown in the figure makes the airflow rise to a comfortable temperature. This will cause condensed water to adhere to the surface of the heat exchanger for a long time, resulting in mold and odor, affecting the air supply quality of the air conditioner. When the air conditioner is used in a vehicle, the generation of condensed water is also likely to cause safety risks, thus affecting the driving safety of the vehicle. In addition, the air conditioner's mode of deep cooling and dehumidifying the airflow before heating will also greatly increase the energy consumption of the air conditioner.

[0045] In the present application, the moisture in the airflow is adsorbed by the rotary dehumidifier 1, and then cooled by the heat exchanger 2. At the same time, the control method of the air conditioner 100 can effectively avoid the generation of condensed water on the surface of the heat exchanger 2, so that mold on the surface of the heat exchanger 2 and odor in the airflow can be avoided, 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 dripping, thereby improving the driving safety of the vehicle. In addition, while meeting the requirements of comfortable air supply, the air conditioner 100 also breaks the mode of the traditional air conditioner 100 that first deeply cools and dehumidifies the airflow and then heats it, which can effectively reduce the energy consumption of the air conditioner 100 and has an energy-saving effect.

[0046] According to the air conditioner 100 of the embodiment of the present invention, by arranging a rotary dehumidifier 1 and a heat exchanger 2 located downstream in the air conditioner 100, the space in the housing 11 of the rotary dehumidifier 1 is divided into a processing area 111 and a regeneration area 112 which are isolated from each other, and the rotary wheel 12 is rotatably arranged in the housing 11 and is divided into a generating part 121 and a regenerating part 122, which can ensure the dehumidification effect and realize the independent adjustment of the humidity and temperature of the air flow to meet the air supply requirements of the user, thereby improving the comfort of the air conditioner 100. It can also avoid the air flow flowing to the heat exchanger 2 from 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 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.

[0047] In some embodiments of the present invention, the rotary dehumidification device 1 further includes a heater, which is arranged in the regeneration zone 112 and is used to heat the rotary wheel 12 to release moisture. The heater heats the generating part 121 transferred to the regeneration zone 112 so that moisture can be precipitated, thereby being converted into the regeneration part 122 to be transferred to the treatment zone 111 for dehumidification again. In this way, the conversion between the generating part 121 and the regeneration part 122 can be realized, thereby realizing the repeated recycling of the rotary wheel 12.

[0048] In some embodiments of the present invention, the rotor 12 is a solid CaCl2 member. The solid CaCl2 member has stable performance and strong moisture absorption capacity. The rotor 12 can be recycled by absorbing and releasing water, which can ensure the dehumidification stability of the rotor dehumidification device 1. In addition, compared with the liquid absorption dehumidification device, the solid CaCl2 dehumidification rotor 12 has no droplet liquid loss, does not need to supplement the moisture absorbent, and does not corrode other metal parts, which can greatly reduce the maintenance cost.

[0049] In some embodiments of the present invention, Figure 2 As shown, the air conditioner 100 further includes: a housing 3, a first sensor 4 and a second sensor 5. The rotary dehumidifier 1 and the heat exchanger 2 are arranged in the housing 3. The housing 3 is provided with an air inlet 31, which is connected to the processing area 111. The first sensor 4 is arranged at the air inlet 31, which is used to detect the temperature and humidity of the airflow entering the rotary dehumidifier 1. The housing 11 is provided with a vent. The second sensor 5 is arranged at the vent, which is used to detect the temperature and humidity of the airflow flowing to the heat exchanger 2. By respectively arranging the first sensor 4 and the second sensor 5 at the air inlet 31 and the vent, the temperature and humidity of the airflow entering the rotary dehumidifier 1 and the temperature and humidity of the airflow flowing to the heat exchanger 2 can be detected in real time, so that the temperature and humidity signals can be transmitted to the processor, so that the processor can send a control signal to the controller through judgment, and finally achieve the adjustment of the air supply temperature and humidity, which can improve the temperature and humidity adjustment accuracy of the air conditioner 100 corresponding to different working conditions, thereby improving the comfort and experience of the user.

[0050] In some embodiments of the present invention, Figure 2 As shown, the air conditioner 100 further includes a blower 6, which is disposed in the housing 3. Along the air flow direction, the blower 6 is disposed downstream of the heat exchanger 2. The housing 3 is provided with an air outlet 32, and the blower 6 is used to drive the air flow from the air inlet 31 to the air outlet 32. By providing the blower 6, power can be provided for the air flow to flow into and out of the air conditioner 100, thereby ensuring the circulation of the air flow in the air conditioner 100, so as to achieve the purpose of adjusting the temperature and humidity of the air flow in the air conditioner 100.

[0051] The following describes a control method of the air conditioner 100 according to an embodiment of the present invention.

[0052] like Figure 1 As shown, the control method of the air conditioner 100 according to the embodiment of the present invention includes:

[0053] Determine that the air conditioner 100 turns on the cooling and dehumidification mode;

[0054] Controlling at least a portion of the regeneration portion 122 to be located in the processing area 111;

[0055] Obtaining the surface temperature T0 of the heat exchanger 2 and the dew point temperature T1 of the airflow flowing to the heat exchanger 2;

[0056] The angle α of the regeneration section 122 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 toward the heat exchanger 2 .

[0057] In the present application, the air conditioner 100 may be provided with a processor and a remote control, the processor being communicatively connected to the remote control, and the user may select different operating modes through buttons on the remote control. For example, when the user selects the cooling mode button and the dehumidification mode button on the remote control, the processor will receive a signal from the remote control, thereby determining to start the cooling and dehumidification mode.

[0058] Preferably, the air conditioner 100 may also be provided with a voice sensor for receiving voice commands from the user. The processor is communicatively connected to the voice sensor. For example, the user may directly convey the need for a 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] Furthermore, the air conditioner 100 is provided with a controller, and the controller is communicatively connected to the processor. The processor can obtain the operating mode of the air conditioner 100 required by the user through a remote control or a voice sensor, and transmit the signal to the controller. The controller thereby sends a control signal to control the wheel 12 and the heat exchanger 2 respectively, thereby adjusting the air supply temperature and humidity of the air conditioner 100.

[0060] When the user selects the cooling and dehumidification mode through the remote control or voice, after the processor receives the instruction of the air conditioner 100 to turn on the cooling and dehumidification mode, it will send the parsed signal to the controller. The controller will control the rotation of the wheel 12 according to the received signal, so that the regeneration part 122 turns into the processing area 111 to absorb the moisture of the air flow, and at the same time adjust the surface temperature of the heat exchanger 2 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 provided 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. 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 for communication. The temperature sensor and the second sensor 5 transmit the measured temperature signal to the processor. The processor obtains the dew point temperature T1 of the airflow flowing to the heat exchanger 2 according to the obtained temperature and humidity of the airflow flowing to the heat exchanger 2, and then compares T1 with T0. Then the processor sends a control signal to the controller according to the comparison result, so that the controller controls the rotation of the rotary wheel 12 and adjusts the angle α of the regeneration part 122 in the processing area 111, so that the dehumidification amount of the rotary 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, so as to avoid the airflow flowing to the heat exchanger 2 from generating condensed water on the surface of the heat exchanger 2.

[0062] In the prior art, when the air conditioner is in the cooling and dehumidification mode, Figure 6 The AC process shown in the figure will reduce the surface temperature of the heat exchanger to below the dew point temperature of the airflow, so that the water in the airflow is separated out to achieve the purpose of dehumidification, and then heat the airflow, such as Figure 6 The CB process shown in the figure makes the airflow rise to a comfortable temperature. This will cause condensed water to adhere to the surface of the heat exchanger for a long time, resulting in mold and odor, affecting the air supply quality of the air conditioner. When the air conditioner is used in a vehicle, the generation of condensed water is also likely to cause safety risks, thus affecting the driving safety of the vehicle. In addition, the air conditioner's mode of deep cooling and dehumidifying the airflow before heating will also greatly increase the energy consumption of the air conditioner.

[0063] In the present application, the moisture in the airflow is adsorbed by the rotary dehumidifier 1, and then cooled by the heat exchanger 2. At the same time, the control method of the air conditioner 100 can effectively avoid the generation of condensed water on the surface of the heat exchanger 2, so that mold on the surface of the heat exchanger 2 and odor in the airflow can be avoided, 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 dripping, thereby improving the driving safety of the vehicle. In addition, while meeting the requirements of comfortable air supply, the air conditioner 100 also breaks the mode of the traditional air conditioner 100 that first deeply cools and dehumidifies the airflow and then heats it, which can effectively reduce the energy consumption of the air conditioner 100 and has an energy-saving effect.

[0064] According to the control method of the air conditioner 100 of the embodiment of the present invention, by setting the rotary dehumidification device 1 and the heat exchanger 2 in the air conditioner 100, the humidity and temperature of the air flow can be independently adjusted to meet the air supply requirements of the user. When the air conditioner 100 turns on the cooling and dehumidification mode, at least part of the regeneration part 122 is controlled to be 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 obtained 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 that the air flow flowing to the heat exchanger 2 can avoid condensation water on the surface of the heat exchanger 2, improve the air supply 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.

[0065] In some embodiments of the present invention, Figure 1-Figure 4 As shown, 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 airflow flowing to the heat exchanger 2 includes:

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

[0067] The angle α at which the regeneration portion 122 is located in the processing area 111 is controlled to increase.

[0068] It can be understood that the processor obtains 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, and then compares T1 with T0. When the processor determines that T0<T1, there is a risk of condensation in the heat exchanger 2, and the processor sends a control signal to the controller. The controller controls the rotation of the rotor 12 to increase the angle α of the regeneration part 122 in the processing area 111, that is, a larger area of ​​the regeneration part 122 contacts the airflow in the processing area 111, thereby increasing the dehumidification capacity of the rotary dehumidifier 1, that is, from Figure 6 The ADE process shown is changed into an A-D′-E′ process, so that the dew point temperature T1 of the air flow to the heat exchanger 2 can be increased.

[0069] 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 preventing the airflow flowing to the heat exchanger 2 from generating condensed water on the surface of the heat exchanger 2. In turn, 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 effects. 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 invention, Figure 1-Figure 4As shown, the control method of the air conditioner 100 further includes:

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

[0072] The surface temperature T0 of the heat exchanger 2 is controlled to increase.

[0073] It is understandable that when the regeneration section 122 is completely located in the processing area 111, the rotary dehumidifier 1 has reached the maximum dehumidification capacity. 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 airflow flowing to the heat exchanger 2, the processor sends a control signal to the controller, so that the controller controls the surface temperature T0 of the heat exchanger 2 to increase, so as to ensure that the dew point temperature T1 of the airflow flowing to the heat exchanger 2 is less than or equal to the surface temperature T0 of the heat exchanger 2, thereby avoiding the airflow flowing to the heat exchanger 2 from generating condensed water on the surface of the heat exchanger 2. In addition, 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 invention, Figure 1 and Figure 2 As shown, 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 airflow flowing to the heat exchanger 2 also includes:

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

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

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

[0078] It is understandable that the processor obtains the dew point temperature T1 of the airflow flowing to the heat exchanger 2 based on the temperature and humidity of the airflow flowing to the heat exchanger 2, and then compares T1 with T0. When the processor determines that T0 ≥ T1, there is no condensation risk in the heat exchanger 2. Then, the processor sends a control signal to the controller based on the obtained user-set outlet humidity h1 and the humidity h2 of the airflow entering the rotary dehumidification device 1, so that the controller controls the rotation of the rotary wheel 12 to adjust the angle α of the regeneration part 122 in the processing area 111, so that the airflow drops to the target humidity. Then, the processor sends a control signal to the controller based on the obtained user-set outlet temperature T2 and the obtained 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, so that the airflow drops to the target temperature.

[0079] In this way, the humidity and temperature of the air flow can be independently adjusted, thereby more accurately controlling the temperature and humidity of the air supplied by the air conditioner 100 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, which is used to detect the temperature and humidity of the airflow entering the rotary dehumidification device 1. The first sensor 4 is communicatively connected to the processor, and the first sensor 4 transmits the measured temperature and humidity signals to the processor, which makes a judgment and transmits the control signal to the controller.

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

[0082] According to the difference a between the outlet humidity h1 set by the air conditioner 100 and the humidity h2 of the air flow entering the rotary dehumidifier 1, the angle α of the regeneration section 122 in the treatment area 111 is adjusted. The larger the difference a is, the larger the angle α of the regeneration section 122 in the treatment area 111 is, and the smaller the difference a is, the smaller the angle α of the regeneration section 122 in the treatment area 111 is.

[0083] The larger the humidity difference a is, the larger the dehumidification capacity of the rotary dehumidifier 1 is required. At this time, the processor sends a control signal to the controller, so that the controller controls the angle α of the regeneration part 122 in the processing area 111 to increase, that is, a larger area of ​​the regeneration part 122 is in contact with the airflow in the processing area 111, thereby achieving an increase in the dehumidification capacity. Conversely, the smaller the humidity difference a is, the smaller the dehumidification capacity of the rotary dehumidifier 1 is required. At this time, the processor sends a control signal to the controller, so that the controller controls the angle α of the regeneration part 122 in the processing area 111 to decrease, that is, a smaller area of ​​the regeneration part 122 is in contact with the airflow in the processing area 111, thereby achieving a decrease in the dehumidification capacity. In this way, the dehumidification capacity of the rotary dehumidifier 1 can be adjusted by controlling the rotation angle of the rotary wheel 12, thereby accurately controlling the air supply humidity of the air conditioner 100 to meet the air supply requirements of the user.

[0084] It should be noted that the angle of the generating portion 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 wheel 12, i.e., the dehumidification amount, and the angle φ of the generating part 121 in the treatment area 111. The wet load of the wheel 12 is inversely proportional to the angle φ of the generating part 121 in the treatment area 111, and directly proportional to the angle α of the regeneration part 122 in the treatment area 111.

[0085] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the control method of the air conditioner 100 further includes:

[0086] Determine that the air conditioner 100 is turned on the dehumidification but not cooling mode;

[0087] Obtain the air outlet humidity h1 set by the air conditioner 100 and the humidity h2 of the air flow entering the rotary dehumidification device 1;

[0088] The angle α of the regeneration section 122 in the processing area 111 is adjusted according to the outlet humidity h1 set by the air conditioner 100 and the humidity h2 of the air flow entering the rotary dehumidifier 1, and the heat exchanger 2 does not work.

[0089] The air conditioner 100 turns on the dehumidification without cooling mode. At this time, there is no need to change the temperature of the airflow, so the heat exchanger 2 does not work. The processor sends a control signal to the controller based on the air outlet humidity h1 set by the user and the humidity h2 of the airflow entering the rotary dehumidifier 1, so that the controller controls the rotation of the rotary wheel 12 to adjust the angle α of the regeneration part 122 in the processing area 111, so that the airflow drops to the target humidity. The air supply humidity of the air conditioner 100 can be accurately controlled to meet the air supply requirements of the user, thereby improving the comfort of the air conditioner 100.

[0090] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the control method of the air conditioner 100 further includes:

[0091] Determine that the air conditioner 100 is turned on in a cooling but not dehumidifying mode;

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

[0093] The angle α of the regeneration portion 122 in the processing area 111 is controlled to be 0°, and the surface temperature of the heat exchanger 2 is adjusted according to the air outlet temperature T2 set by the air conditioner 100 and the temperature T3 of the air flow flowing to the heat exchanger 2 .

[0094] The air conditioner 100 is turned on in the cooling but not dehumidifying mode. At this time, there is no need to change the humidity of the airflow. Therefore, the angle α of the regeneration unit 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 unit 121. The processor sends a control signal to the controller based on the obtained user-set air outlet temperature T2 and the obtained 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 air supply temperature of the air conditioner 100 can be accurately controlled to meet the user's air supply requirements, thereby improving the comfort of the air conditioner 100.

[0095] A vehicle according to an embodiment of the present invention includes: the air conditioner 100 described above.

[0096] According to the vehicle of the embodiment of the present invention, by arranging a rotary dehumidifier 1 and a heat exchanger 2 located downstream in the air conditioner 100, the space in the housing 11 of the rotary dehumidifier 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 housing 11 and is divided into a generating part 121 and a regenerating part 122, which can ensure the dehumidification effect and realize the independent adjustment of the humidity and temperature of the air flow to meet the air supply requirements of the user, thereby improving the comfort of the air conditioner 100. It can also avoid the air flow flowing to the heat exchanger 2 from 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 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.
