Background Technology

[0002] With the continuous rise and development of outdoor camping, more and more people are enthusiastic about participating in outdoor activities such as camping, fishing, and picnicking. However, the ever-changing outdoor environment constantly tests people, especially in summer. Harsh conditions such as scorching sun, high temperatures, and high humidity not only limit people's outdoor activities but can even threaten their health and lives. The advent of portable outdoor camping air conditioners has largely solved the cooling needs of people participating in outdoor activities. With its advantages of being compact, lightweight, and providing ample cooling capacity, outdoor camping air conditioners remain an essential piece of equipment for outdoor camping enthusiasts.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] While there are many types of portable outdoor air conditioners, most have simple control methods. Their operation in cooling or heating modes includes: fixed operating frequency mode, where the air conditioner operates at a predetermined frequency based on the user-selected mode (e.g., powerful mode, cooling mode, heating mode), without involving other frequency adjustments; and supply air temperature difference control mode, which calculates the temperature difference between the actual supply air temperature and the target supply air temperature based on the user-set target temperature and then performs frequency adjustment control. Both of these control methods only consider whether the air conditioner's operating parameters reach the set target values, neglecting user comfort. There is no closed-loop control between the user and the air conditioner, resulting in limited functionality and a simplistic control method.

[0031] Therefore, this invention provides an air conditioner control method that combines multiple parameters such as geographical location information, time information, and user body temperature to control the air conditioner's operating mode, compressor frequency, internal fan speed, and air guide plate position. This improves the air delivery comfort of the portable air conditioner in both cooling and heating modes, making the air conditioner control strategy more aligned with the user's actual needs.

[0032] According to an embodiment of the present invention, a control method for an air conditioner is provided. The air conditioner includes an evaporator side, a condenser side, and a compressor. The evaporator side is provided with an internal fan and an air guide plate. The air conditioner's operating mode includes a comfort mode, which can adjust the air outlet temperature of the air conditioner to make the user's perceived temperature within a comfortable range. When the user activates the comfort mode, the control method of the present invention is executed. Figure 1 The diagram shows a flowchart of an embodiment of the method of the present invention. The air conditioner control method may include steps S110 and S120.

[0033] In step S110, after the air conditioner is turned on and the comfort mode is activated, the geographical location information of the air conditioner, the current time information, the dry bulb temperature of the supply air, the relative humidity of the supply air, the airflow speed of the internal fan, and the user's body temperature are obtained.

[0034] like Figure 4The air conditioner control system structure of the present invention is shown, comprising: a Bluetooth module, a central control module, a sensor module, an actuator module, and a comfort mode control module. The comfort mode control module includes an optimal comfort temperature calculation module and a body temperature calculation module; used to implement the air conditioner's comfort mode. Specifically, as shown... Figure 5 The schematic diagram of the control logic shown illustrates the specific functions of each module:

[0035] The timing module is used to time the control commands when the air conditioner is in comfort mode.

[0036] The Bluetooth module is used to connect to the user's mobile phone when the air conditioner is in comfort mode, and obtain the relevant calculation parameters required for control through the network.

[0037] The sensor module includes a temperature sensor, a humidity sensor, and an infrared human body temperature monitor. Specifically, the temperature sensor is located at the air outlet of the air conditioner evaporator to detect the dry-bulb temperature of the air supplied by the air conditioner and feeds the obtained dry-bulb temperature information back to the central control module; the humidity sensor is located at the air outlet of the air conditioner evaporator to detect the relative humidity of the air supplied by the air conditioner and feeds the obtained relative humidity information back to the central control module; the infrared human body temperature monitor is located in the air conditioner to detect the human body surface temperature and feeds the obtained human body surface temperature information back to the central control module.

[0038] The actuator module includes a compressor module, an indoor fan module, and an air guide plate module. Specifically, the compressor module is the core power component that provides cooling or heating in the air conditioner; the indoor fan module is the power component that delivers airflow to the user and is located at the evaporator end of the air conditioner; the air guide plate module is an air guiding component that adjusts the airflow angle of the air outlet at the evaporator end of the air conditioner and is located at the air outlet at the evaporator end of the air conditioner. The operation of the air guide plate can realize the left and right swinging airflow action.

[0039] The comfort mode control module includes an optimal comfort temperature calculation module and a perceived temperature calculation module. Specifically, the optimal comfort temperature calculation module stores an algorithm model for calculating the optimal comfort temperature. Its operation requires the central control module to activate a Bluetooth module to connect to the user's mobile phone and obtain the necessary calculation parameters via the internet. The perceived temperature calculation module stores an algorithm model for calculating the perceived temperature. Its operation first requires the optimal comfort temperature module to calculate the optimal comfort temperature and then transmit the calculated value to the perceived temperature calculation module. Then, the central control module activates a sensor module to obtain the current air conditioner's supply air dry-bulb temperature and relative humidity. Finally, this information is aggregated into the perceived temperature calculation module's algorithm model to complete the perceived temperature calculation.

[0040] The central control module is the core control unit of the air conditioner. It is used to: activate the Bluetooth module to connect to the user's mobile phone and obtain the calculation parameters needed to calculate the optimal comfort temperature; activate the sensor module to obtain parameters including the dry-bulb temperature of the supply air, the relative humidity of the supply air, and human body temperature; activate the comfort mode control module, where the optimal comfort temperature module calculates the optimal comfort temperature, and the perceived temperature calculation module calculates the perceived temperature; and activate the actuator module, through the coordinated work of the compressor module, the indoor fan module, and the air guide plate module, to jointly execute the air conditioner's comfort mode.

[0041] In some embodiments, before acquiring the geographical location information of the air conditioner, the current time information, the dry-bulb temperature of the supply air, the relative humidity of the supply air, and the user's body temperature after the air conditioner is turned on and the comfort mode is activated, the method further includes:

[0042] The system controls the compressor to stop running, the indoor fan to run at maximum speed, and the air guide plate to be positioned at the optimal windward position. This optimal windward position is where the air resistance from the air guide plate to the indoor fan is minimized, and the airflow from the indoor fan is maximized when the air guide plate is in this position. For example, for a left-right swinging air guide plate, when it is in the center of its swing, the resistance to the airflow from the indoor unit is minimized, allowing for thorough mixing of the air from the air conditioning unit with air from other locations. This results in more accurate measurements of the supply air dry-bulb temperature and relative humidity, facilitating subsequent control.

[0043] The air conditioner is controlled to establish a connection with the user's mobile terminal, so that the air conditioner can connect to the network through the mobile terminal to obtain the geographical location information of the air conditioner's location and the current time information.

[0044] Specifically, after the user activates the comfort mode, the central control module, upon receiving the activation command, first issues a self-test command for the comfort mode. This includes: activating the timing module to begin a self-test timing period of ΔT1 (range 1–3 minutes, preferably 90 seconds); sending a command to the compressor module, which, if running, immediately stops the compressor and remains in a stopped state; sending a command to the air guide module, which resets the air guide and ultimately controls it to the most favorable airflow position, i.e., centered left and right; sending a command to the internal fan module, which, if running at other speeds, immediately switches the internal fan to its maximum speed and runs it continuously for ΔT2 (range 1–3 minutes, preferably 80 seconds); and sending a command to the Bluetooth module, which, upon receiving the command, sends a connection command to the user's mobile phone and obtains network access through the user's phone.

[0045] After completing the self-test mode, the central control module sends commands to the Bluetooth module, sensor module, and timing module to obtain the parameter information required by the central control module. Since the air conditioner may be operating in other modes before activating the comfort mode, and the temperature of the heat exchanger may differ significantly from the ambient temperature, executing the self-test mode helps avoid large discrepancies between the environmental parameters collected by the sensors and the actual ambient temperature, thus facilitating subsequent control decisions.

[0046] When acquiring parameter information, the Bluetooth module receives the instruction from the central control module and uses the user's mobile phone's network function to obtain information including the latitude of the air conditioner's location, the current month, and the altitude of the air conditioner's location, and then feeds this information back to the central control module.

[0047] After receiving instructions from the central control module, the temperature sensor, with the assistance of the timing module, controls the temperature sensor to continuously collect 5 sets of supply air dry-bulb temperature data at time intervals of ΔT3 (range 1-20s, preferred value 5s). Then, the data acquisition module calculates the average value of the 5 sets of supply air dry-bulb temperature data and feeds back the average supply air dry-bulb temperature value as the current supply air dry-bulb temperature value of the room where the air conditioner is located to the central control module.

[0048] After receiving instructions from the central control module, the humidity sensor, with the cooperation of the timing module, controls the humidity sensor to continuously collect 5 sets of relative humidity data of the supply air at time intervals of △T3. Then, the data acquisition module calculates the average value of the 5 sets of relative humidity data of the supply air and feeds back the average value of the supply air relative humidity of the room where the air conditioner is located to the central control module.

[0049] After receiving instructions from the central control module, the infrared human body temperature monitor, with the cooperation of the timing module, uses the sensor module to control the infrared human body temperature monitor to continuously collect 5 sets of human body temperature parameters within the monitoring range of the infrared monitor at time intervals of △T3. Then, the data acquisition module calculates the average value of the 5 sets of human body temperature data and feeds back the average human body temperature value as the current user's body temperature value to the central control module.

[0050] When the infrared human body temperature monitor fails to detect body temperature for five consecutive sets of parameters within its monitoring range, it sends feedback to the sensor module, which in turn relays this information to the central control module. The central control module then determines that the area within the air conditioner's airflow range is unoccupied. At this point, the central control module sends a command to the Bluetooth module, which in turn sends a notification to the user's mobile phone or displays a notification on the air conditioner's display panel, informing the user that "the area around the air conditioner is currently unoccupied or people are far away; do you wish to continue with the comfort mode?" If the user selects to continue with the comfort mode via their mobile phone, the air conditioner continues to operate. If the user selects not to run the comfort mode via their mobile phone, the air conditioner enters standby mode.

[0051] Specifically, after sending the prompt message, the system retains a duration of △T4 (ranging from 1 to 20 minutes, with a preferred value of 10 minutes) for user confirmation. Within △T4, if the user confirms the air conditioner is running via their mobile phone or the air conditioner's panel, the air conditioner will execute the corresponding operating instructions according to the user's commands. If the user does not confirm the air conditioner is running via their mobile phone or the air conditioner's panel within △T4, the central control module will instruct the air conditioner to stop. If the user selects to confirm the air conditioner continues to run in the comfort mode, and the system still cannot detect the user's body temperature, the central control module will set the user's body temperature data to the default 37.5℃.

[0052] In step S120, based on the geographical location information of the air conditioner, the current time information, the dry bulb temperature of the supply air, the relative humidity of the supply air, the air speed of the internal fan, and the body temperature of the user, the operating mode of the air conditioner, the frequency of the compressor, the rotation speed of the internal fan, and the position of the air guide plate are controlled.

[0053] In some implementations, the geographical location information of the air conditioner includes the latitude and altitude information of the location of the air conditioner; the current time information includes the current month information.

[0054] In some implementations, step S120 involves controlling the air conditioner's operating mode, compressor frequency, internal fan speed, and the position of the air guide plate based on the geographical location information of the air conditioner's location, the current time information, the dry-bulb temperature of the supply air, the relative humidity of the supply air, the airflow speed of the internal fan, and the user's body temperature. For example... Figure 2 As shown, it includes steps S210 to S230.

[0055] Step S210: Determine the optimal comfort temperature based on the latitude and altitude information of the air conditioner's location, as well as the current month information. The formula for calculating the optimal comfort temperature is:

[0056] T s =22.7×[1+0.3×sin(φ-23.5)]-|0.3×cos[15°×(M-1)]|-2×tan(H / 100)

[0057] In the formula, This section provides the latitude information of the air conditioner's location, M represents the current month (e.g., January corresponds to a value of 1, February to a value of 2, and so on), H represents the altitude information of the air conditioner's location (e.g., 10m altitude corresponds to a value of 10, 100m altitude to a value of 100, and so on), and T represents the latitude information of the air conditioner's location. s For optimal comfort temperature.

[0058] Specifically, the central control module will send the relevant parameters obtained in the self-test mode to the comfort mode control module, and the optimal comfort temperature will be calculated in the optimal comfort temperature calculation module of the comfort mode control module.

[0059] Once the optimal comfort temperature calculation module completes the first set of optimal comfort temperature calculations, it stores these values. When the central control module receives confirmation from the user to continue running the comfort mode, the timing module begins executing timing commands. The timing module times the duration according to ΔT5 (ranging from 1 to 10 minutes, with a preferred value of 5 minutes). Each time the timing module completes a ΔT5 duration, it sends a signal back to the central control module. Upon receiving this signal, the central control module sends a command to the optimal comfort temperature calculation module to recall the optimal comfort temperature. Upon receiving this signal from the central control module, the optimal comfort temperature calculation module sends the first set of optimal comfort temperature values ​​previously stored therein to the comfort temperature calculation module for real-time updates of the calculated comfort temperature and subsequent adjustments to the control strategy.

[0060] Step S220: Determine the perceived temperature based on the optimal comfort temperature, the dry-bulb temperature of the supply air, the relative humidity of the supply air, and the airflow speed of the internal fan.

[0061] Specifically, before calculating the perceived temperature, the relationship between the dry-bulb temperature of the supply air and the optimal comfort temperature is determined. If the dry-bulb temperature of the supply air is greater than or equal to the optimal comfort temperature, then the formula for calculating the perceived temperature is:

[0062] T g =T a +14×[exp(0.05×(T a -T s )×(RH-RH S ))]-0.03×(T a -T s )×v

[0063] If the dry-bulb temperature of the supplied air is lower than the optimal comfort temperature, then the formula for calculating the perceived temperature is:

[0064] T g =T a -14×[exp(0.05×(T s -T a )×(RH-RH S ))]-0.01×(T s -T a )×v

[0065] In the formula, T g The perceived temperature is the temperature felt by the body. It reflects the human body's perception of the external thermal environment and is a comprehensive response to the degree of hotness or coldness of the external environment, focusing on comfort from the human perspective. (T) a RH represents the dry-bulb temperature of the supply air, and RH represents the relative humidity of the supply air. s The optimal air humidity can be set to 55%; v represents the airflow speed of the internal fan, calculated from the internal fan speed. An internal fan speed-wind speed correspondence table is pre-stored in the central control module. During actual operation, the central control module retrieves the internal fan speed information, identifies the corresponding wind speed value in the internal fan speed-wind speed correspondence table, and then sends this value to the perceived temperature calculation module for calculation.

[0066] Specifically, after the perceived temperature calculation module receives the optimal comfort temperature value from the optimal comfort temperature calculation module, it will send a set of signals to the central control module. Upon receiving these signals, the central control module will activate the sensor module to complete a data acquisition. Specifically, the sensor module will activate the temperature sensor, humidity sensor, and infrared human body temperature monitor to collect data on the dry-bulb temperature and relative humidity of the air conditioner's supply air, as well as human body temperature parameters within the air conditioner's supply area. If no human body temperature parameters are collected, they will be set to the default value of 37.5℃. Once the perceived temperature module receives the optimal comfort temperature value from the optimal comfort temperature calculation module and the air conditioner's supply air dry-bulb temperature and relative humidity values ​​from the central control module, it will begin calculating the perceived temperature.

[0067] Step S230: Based on the dry-bulb temperature of the supplied air, the optimal comfort temperature, the perceived temperature, and the user's body temperature, control the operating mode of the air conditioner, the frequency of the compressor, the speed of the internal fan, and the position of the air guide plate.

[0068] This solution calculates the optimal comfort temperature and perceived temperature, and controls the air conditioner's operating mode and the operating status of the compressor, internal fan, and air guide plate accordingly. This makes the portable air conditioner more comfortable to deliver air, improves its adaptability, and makes the control strategy more tailored to the user's actual needs.

[0069] In some embodiments, step S230, which involves controlling the operating mode of the air conditioner, the frequency of the compressor, the speed of the internal fan, and the position of the air guide plate based on the dry-bulb temperature of the supplied air, the optimal comfort temperature, the perceived temperature, and the user's body temperature, includes steps S310 to S360.

[0070] Step S310: Determine the range of the difference between the user's body temperature and the standard body temperature.

[0071] Step S320: If the difference is within the first range, control the air conditioner to operate in cooling mode; increase the frequency of the compressor to the first set frequency, and then control the compressor to increase the frequency at the first set rate; control the speed of the internal fan to the highest speed and the position of the air guide plate to the most favorable position.

[0072] Step S330: If the difference is within the second range, control the air conditioner to operate in cooling mode; control the compressor to increase its frequency to the second set frequency, and then control the compressor to increase its frequency at the second set rate; control the speed of the internal fan to the medium speed and the position of the air guide plate to the most favorable position.

[0073] Step S340: If the difference is within the third range, control the compressor to increase its frequency to the third set frequency, the internal fan to operate at a low speed, and the air guide to swing; and control the frequency of the compressor according to the dry bulb temperature of the supplied air, the optimal comfort temperature, and the perceived temperature.

[0074] In some embodiments, step S340, the specific process of controlling the frequency of the compressor based on the dry-bulb temperature of the supply air, the optimal comfort temperature, and the perceived temperature, includes steps S410 to S430.

[0075] Step S410: Determine the relationship between the dry-bulb temperature of the supplied air and the optimal comfort temperature, and determine the relationship between the perceived temperature and the set temperature. The set temperature is the ambient comfort temperature, set to 25℃.

[0076] Step S420: If the dry bulb temperature of the supplied air is lower than the optimal comfort temperature and the perceived temperature is lower than the set temperature, then control the compressor to increase its frequency according to the third set rate.

[0077] Step S430: If the dry bulb temperature of the supplied air is less than the optimal comfort temperature and the perceived temperature is less than the set temperature, then control the compressor to reduce its frequency at a third set rate, and the frequency of the compressor is not lower than the third set frequency.

[0078] Step S350: If the difference is within the fourth range, control the air conditioner to operate in heating mode; control the compressor to increase its frequency to the fourth set frequency, and then control the compressor to increase its frequency at the fourth set rate; control the speed of the indoor fan to the medium speed and the position of the air guide plate to the most favorable position.

[0079] Step S360: If the difference is within the fifth range, control the air conditioner to operate in heating mode; increase the compressor frequency to the fifth set frequency, and then control the compressor to increase the frequency at the fifth set rate; control the speed of the internal fan to the highest speed and the position of the air guide plate to the most favorable position.

[0080] Specifically, after obtaining three sets of parameters, including the human body temperature Tp, the optimal comfort temperature Ts, and the perceived temperature Tg within the air supply range of the air conditioner, the central control module first executes the judgment strategy to determine the range of the difference between the human body temperature Tp and the standard body temperature "37.5℃", and then determines whether the human body surface temperature is in an overheated or overcooled state, and then determines the corresponding control strategy based on the range. When Tp-37.5℃ ≥ 0.5℃, i.e. the difference is in the first range, comfort control strategy 1 is implemented; when 0.5℃ > Tp-37.5℃ > 0.3℃, i.e. the difference is in the second range, comfort control strategy 2 is implemented; when 0.3℃ ≥ Tp-37.5℃ ≥ -0.3℃, i.e. the difference is in the third range, comfort control strategy 3 is implemented; when -0.3℃ > Tp-37.5℃ ≥ -0.5℃, i.e. the difference is in the fourth range, comfort control strategy 4 is implemented; when -0.5℃ > Tp-37.5℃, i.e. the difference is in the fifth range, comfort control strategy 5 is implemented.

[0081] Comfort control strategy 1 is as follows: The system believes that the human body is in an overheated state under the current conditions. The system selects to execute the cooling command and starts the cooling mode. At this time, the compressor module first executes the frequency increase to the target frequency of 65Hz, and then executes the frequency increase control strategy of 10Hz / min. The indoor fan module executes the high fan speed, and the air guide plate module executes the most favorable air outlet position (i.e., the left and right center position) until the air conditioner outlet temperature reaches the temperature value of "optimal comfort temperature Ts minus 5℃". After that, the dry bulb temperature, relative humidity, and human body temperature are re-acquired to adjust the comfort control strategy until the human body temperature is within the range of comfort.

[0082] Comfort control strategy 2 is as follows: The system assumes that the human body is in a slightly warm state at the current state. The system selects to execute the cooling command and turns on the cooling mode. At this time, the compressor module first executes the frequency increase to the target frequency of 50Hz, and then executes the frequency increase control strategy of 6Hz / min. The indoor fan module executes the medium fan speed, and the air guide plate module executes the most favorable air outlet position, until the air outlet temperature of the air conditioner reaches the temperature value of "optimal comfort temperature Ts minus 2℃". After that, the dry bulb temperature, relative humidity, and human body temperature are re-acquired to adjust the comfort control strategy until the human body temperature is within the range of comfort.

[0083] Comfort control strategy 3 is as follows: the system assumes that the human body is in a neutral state under the current conditions. The compressor module increases the frequency to the target frequency of 30Hz, the internal fan module operates at a low fan speed, the air guide plate module swings left and right, and the compressor frequency is controlled according to the dry bulb temperature of the supplied air, the optimal comfort temperature, and the perceived temperature.

[0084] Specifically, it is determined whether the dry-bulb temperature Ta of the supply air meets the target value of the calculated optimal comfort temperature Ts ± 1℃, and whether the perceived temperature Tg meets the target value of 25 ± 1℃. When the air conditioner selects to implement comfort control strategy 3, the air conditioner is considered to be in the optimal comfort air supply condition if either of the above two judgment conditions is met during operation. If the dry-bulb temperature Ta of the air conditioner supply air is < optimal comfort temperature Ts ± 1℃ and the perceived temperature Tg is < 25 ± 1℃, the compressor will operate at a frequency increase control strategy of 3Hz / min until either of the above two judgment conditions is met; if the dry-bulb temperature Ta of the supply air is > optimal comfort temperature Ts ± 1℃ and the perceived temperature Tg is > 25 ± 1℃, the compressor will operate at a frequency decrease control strategy of 3Hz / min, and the compressor's operating frequency will not be lower than 30Hz. If this continues for a duration of △T6 (within the range of 5 to 30 minutes, preferably 20 minutes), the compressor will be shut down.

[0085] Comfort control strategy 4 is as follows: The system assumes that the human body is in a slightly cold state at the current state, so the system selects to execute the heating command and start the heating mode. At this time, the compressor module first executes the frequency increase to the target frequency of 50Hz, and then executes the frequency increase control strategy of 6Hz / min. The indoor fan module executes the medium fan speed, and the air guide plate module executes the most favorable air outlet position, until the air outlet temperature of the air conditioner reaches the temperature value of "optimal comfort temperature Ts plus 2℃". After that, the dry bulb temperature, relative humidity, and human body temperature are re-acquired to adjust the comfort control strategy until the human body temperature is within the range of comfort.

[0086] Comfort control strategy 5 is as follows: If the system determines that the human body is in an overly cold state, the system will execute the heating command and start the heating mode. At this time, the compressor module will first increase the frequency to the target frequency of 65Hz, and then follow the frequency increase control strategy of 10Hz / min. The indoor fan module will run at a high fan speed, and the air guide module will run at the most favorable air outlet position until the air outlet temperature of the air conditioner reaches the temperature value of "optimal comfort temperature Ts plus 5℃". After that, the dry bulb temperature, relative humidity, and human body temperature will be reacquired to adjust the comfort control strategy until the human body temperature is within the range of comfort.

[0087] Figure 6 This is a flowchart illustrating an embodiment of the comfort mode of the air conditioner of the present invention, as shown below. Figure 6 As shown, the method for implementing a comfortable body sensation mode in this invention includes:

[0088] Step 1: According to control measure 1, execute the self-test mode. Through the joint operation of the compressor module, air guide plate module and internal fan module, obtain the current ambient air dry bulb temperature, relative humidity and human body temperature of the room where the air conditioner is located, so as to facilitate the selection of subsequent control decisions.

[0089] Step 2: Calculate the optimal comfort temperature Ts according to control measure 2. Calculate and obtain the optimal comfort temperature Ts of the current environment of the air conditioner. Use this temperature to determine the formula for calculating the perceived temperature in control measure 3, so as to update the calculated value of the perceived temperature Tg in real time and adjust the subsequent control strategy.

[0090] Step 3: Calculate the perceived temperature Tg according to control measure 3. Calculate the perceived temperature Tg of the current environment of the air conditioner according to the optimal comfort temperature Ts calculated in control measure 2.

[0091] Step 4: Implement the comfort control strategy according to control measure 4. Select a specific comfort control strategy based on the three sets of parameters calculated within the air supply range of the air conditioner: human body temperature Tp, optimal comfort temperature Ts, and perceived temperature Tg.

[0092] By employing the technical solution of this embodiment, when a user activates the comfort mode, different control strategies can be selected based on the geographical location of the air conditioner, current time, dry-bulb temperature of the supply air, relative humidity of the supply air, airflow speed of the internal fan, and the user's body temperature. These strategies control the air conditioner's operating mode, compressor frequency, internal fan speed, and air guide vane position. By determining the air conditioner control strategy based on the actual usage environment, the user's perceived temperature is kept within a comfortable range, improving the air conditioner's adaptability and meeting the needs of various outdoor scenarios.

[0093] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. The air conditioner includes an evaporator side, a condenser side, and a compressor. The evaporator side is provided with an internal fan and an air guide plate. The air conditioner's operating mode includes a comfort mode, which adjusts the air outlet temperature of the air conditioner to ensure the user's perceived temperature is within a comfortable range. When the user activates the comfort mode, the control method of the present invention is executed. See also... Figure 3 The diagram shows a structural schematic of an embodiment of the device of the present invention. The control device for the air conditioner may include: an acquisition unit 102 and a control unit 104.

[0094] The acquisition unit 102 is configured to acquire, after the air conditioner is turned on and the comfort mode is activated, the geographical location information of the air conditioner, the current time information, the dry-bulb temperature of the supply air, the relative humidity of the supply air, the airflow speed of the internal fan, and the user's body temperature. For the specific functions and processing of this acquisition unit 102, please refer to step S110.

[0095] like Figure 4 The air conditioner control system structure of the present invention is shown, comprising: a Bluetooth module, a central control module, a sensor module, an actuator module, and a comfort mode control module. The comfort mode control module includes an optimal comfort temperature calculation module and a body temperature calculation module; used to implement the air conditioner's comfort mode. Specifically, as shown... Figure 5 The schematic diagram of the control logic shown illustrates the specific functions of each module:

[0096] The timing module is used to time the control commands when the air conditioner is in comfort mode.

[0097] The Bluetooth module is used to connect to the user's mobile phone when the air conditioner is in comfort mode, and obtain the relevant calculation parameters required for control through the network.

[0098] The sensor module includes a temperature sensor, a humidity sensor, and an infrared human body temperature monitor. Specifically, the temperature sensor is located at the air outlet of the air conditioner evaporator to detect the dry-bulb temperature of the air supplied by the air conditioner and feeds the obtained dry-bulb temperature information back to the central control module; the humidity sensor is located at the air outlet of the air conditioner evaporator to detect the relative humidity of the air supplied by the air conditioner and feeds the obtained relative humidity information back to the central control module; the infrared human body temperature monitor is located in the air conditioner to detect the human body surface temperature and feeds the obtained human body surface temperature information back to the central control module.

[0099] The actuator module includes a compressor module, an indoor fan module, and an air guide plate module. Specifically, the compressor module is the core power component that provides cooling or heating in the air conditioner; the indoor fan module is the power component that delivers airflow to the user and is located at the evaporator end of the air conditioner; the air guide plate module is an air guiding component that adjusts the airflow angle of the air outlet at the evaporator end of the air conditioner and is located at the air outlet at the evaporator end of the air conditioner. The operation of the air guide plate can realize the left and right swinging airflow action.

[0100] The comfort mode control module includes an optimal comfort temperature calculation module and a perceived temperature calculation module. Specifically, the optimal comfort temperature calculation module stores an algorithm model for calculating the optimal comfort temperature. Its operation requires the central control module to activate a Bluetooth module to connect to the user's mobile phone and obtain the necessary calculation parameters via the internet. The perceived temperature calculation module stores an algorithm model for calculating the perceived temperature. Its operation first requires the optimal comfort temperature module to calculate the optimal comfort temperature and then transmit the calculated value to the perceived temperature calculation module. Then, the central control module activates a sensor module to obtain the current air conditioner's supply air dry-bulb temperature and relative humidity. Finally, this information is aggregated into the perceived temperature calculation module's algorithm model to complete the perceived temperature calculation.

[0101] The central control module is the core control unit of the air conditioner. It is used to: activate the Bluetooth module to connect to the user's mobile phone and obtain the calculation parameters needed to calculate the optimal comfort temperature; activate the sensor module to obtain parameters including the dry-bulb temperature of the supply air, the relative humidity of the supply air, and human body temperature; activate the comfort mode control module, where the optimal comfort temperature module calculates the optimal comfort temperature, and the perceived temperature calculation module calculates the perceived temperature; and activate the actuator module, through the coordinated work of the compressor module, the indoor fan module, and the air guide plate module, to jointly execute the air conditioner's comfort mode.

[0102] In some embodiments, before acquiring the geographical location information of the air conditioner, the current time information, the dry-bulb temperature of the supply air, the relative humidity of the supply air, and the user's body temperature after the air conditioner is turned on and the comfort mode is activated, the control unit 104 further includes:

[0103] The control unit 104 is further configured to control the compressor to stop running, the indoor fan to run at its maximum speed, and the air guide plate to be in the most favorable wind position. The most favorable wind position is the position where the air guide plate exerts the least resistance to the airflow from the indoor fan, and the indoor fan's airflow is maximized when the air guide plate is in this position. For example, for a left-right swinging air guide plate, when the air guide plate is in the center of its swing, the resistance to the airflow from the indoor unit is minimized, allowing for thorough mixing of the air from the air conditioner with air from other locations. This results in more accurate measurements of the supply air dry-bulb temperature and relative humidity, facilitating subsequent control.

[0104] The control unit 104 is further configured to control the air conditioner to establish a connection with the user's mobile terminal, so that the air conditioner can connect to the network through the mobile terminal to obtain the geographical location information of the air conditioner and the current time information.

[0105] Specifically, after the user activates the comfort mode, the central control module, upon receiving the activation command, first issues a self-test command for the comfort mode. This includes: activating the timing module to begin a self-test timing period of ΔT1 (range 1–3 minutes, preferably 90 seconds); sending a command to the compressor module, which, if running, immediately stops the compressor and remains in a stopped state; sending a command to the air guide module, which resets the air guide and ultimately controls it to the most favorable airflow position, i.e., centered left and right; sending a command to the internal fan module, which, if running at other speeds, immediately switches the internal fan to its maximum speed and runs it continuously for ΔT2 (range 1–3 minutes, preferably 80 seconds); and sending a command to the Bluetooth module, which, upon receiving the command, sends a connection command to the user's mobile phone and obtains network access through the user's phone.

[0106] After completing the self-test mode, the central control module sends commands to the Bluetooth module, sensor module, and timing module to obtain the parameter information required by the central control module. Since the air conditioner may be operating in other modes before activating the comfort mode, and the temperature of the heat exchanger may differ significantly from the ambient temperature, executing the self-test mode helps avoid large discrepancies between the environmental parameters collected by the sensors and the actual ambient temperature, thus facilitating subsequent control decisions.

[0107] When acquiring parameter information, the Bluetooth module receives the instruction from the central control module and uses the user's mobile phone's network function to obtain information including the latitude of the air conditioner's location, the current month, and the altitude of the air conditioner's location, and then feeds this information back to the central control module.

[0108] After receiving instructions from the central control module, the temperature sensor, with the assistance of the timing module, controls the temperature sensor to continuously collect 5 sets of supply air dry-bulb temperature data at time intervals of ΔT3 (range 1-20s, preferred value 5s). Then, the data acquisition module calculates the average value of the 5 sets of supply air dry-bulb temperature data and feeds back the average supply air dry-bulb temperature value as the current supply air dry-bulb temperature value of the room where the air conditioner is located to the central control module.

[0109] After receiving instructions from the central control module, the humidity sensor, with the cooperation of the timing module, controls the humidity sensor to continuously collect 5 sets of relative humidity data of the supply air at time intervals of △T3. Then, the data acquisition module calculates the average value of the 5 sets of relative humidity data of the supply air and feeds back the average value of the supply air relative humidity of the room where the air conditioner is located to the central control module.

[0110] After receiving instructions from the central control module, the infrared human body temperature monitor, with the cooperation of the timing module, uses the sensor module to control the infrared human body temperature monitor to continuously collect 5 sets of human body temperature parameters within the monitoring range of the infrared monitor at time intervals of △T3. Then, the data acquisition module calculates the average value of the 5 sets of human body temperature data and feeds back the average human body temperature value as the current user's body temperature value to the central control module.

[0111] When the infrared human body temperature monitor fails to detect body temperature for five consecutive sets of parameters within its monitoring range, it sends feedback to the sensor module, which in turn relays this information to the central control module. The central control module then determines that the area within the air conditioner's airflow range is unoccupied. At this point, the central control module sends a command to the Bluetooth module, which in turn sends a notification to the user's mobile phone or displays a notification on the air conditioner's display panel, informing the user that "the area around the air conditioner is currently unoccupied or people are far away; do you wish to continue with the comfort mode?" If the user selects to continue with the comfort mode via their mobile phone, the air conditioner continues to operate. If the user selects not to run the comfort mode via their mobile phone, the air conditioner enters standby mode.

[0112] Specifically, after sending the prompt message, the system retains a duration of △T4 (ranging from 1 to 20 minutes, with a preferred value of 10 minutes) for user confirmation. Within △T4, if the user confirms the air conditioner is running via their mobile phone or the air conditioner's panel, the air conditioner will execute the corresponding operating instructions according to the user's commands. If the user does not confirm the air conditioner is running via their mobile phone or the air conditioner's panel within △T4, the central control module will instruct the air conditioner to stop. If the user selects to confirm the air conditioner continues to run in the comfort mode, and the system still cannot detect the user's body temperature, the central control module will set the user's body temperature data to the default 37.5℃.

[0113] Control unit 104 is configured to control the operating mode of the air conditioner, the frequency of the compressor, the rotational speed of the indoor fan, and the position of the air guide plate based on the geographical location information of the air conditioner's location, the current time information, the dry-bulb temperature of the supply air, the relative humidity of the supply air, the airflow speed of the indoor fan, and the user's body temperature. The specific functions and processing of this control unit 104 are described in step S120.

[0114] In some implementations, the geographical location information of the air conditioner includes the latitude and altitude information of the location of the air conditioner; the current time information includes the current month information.

[0115] In some embodiments, the control unit 104 controls the operating mode of the air conditioner, the frequency of the compressor, the rotational speed of the indoor fan, and the position of the air guide plate based on the geographical location information of the air conditioner's location, the current time information, the dry-bulb temperature of the supply air, the relative humidity of the supply air, the airflow speed of the indoor fan, and the user's body temperature, including:

[0116] The control unit 104 is further configured to determine the optimal comfort temperature based on the latitude and altitude information of the air conditioner's location, as well as the current month information. The specific functions and processing of this control unit 104 are described in step S210. The formula for calculating the optimal comfort temperature is:

[0117] T s =22.7×[1+0.3×sin(φ-23.5)]-|0.3×cos[15°×(M-1)]|-2×tan(H / 100)

[0118] In the formula, This section provides the latitude information of the air conditioner's location, M represents the current month (e.g., January corresponds to a value of 1, February to a value of 2, and so on), H represents the altitude information of the air conditioner's location (e.g., 10m altitude corresponds to a value of 10, 100m altitude to a value of 100, and so on), and T represents the latitude information of the air conditioner's location. s For optimal comfort temperature.

[0119] Specifically, the central control module will send the relevant parameters obtained in the self-test mode to the comfort mode control module, and the optimal comfort temperature will be calculated in the optimal comfort temperature calculation module of the comfort mode control module.

[0120] Once the optimal comfort temperature calculation module completes the first set of optimal comfort temperature calculations, it stores these values. When the central control module receives confirmation from the user to continue running the comfort mode, the timing module begins executing timing commands. The timing module times the duration according to ΔT5 (ranging from 1 to 10 minutes, with a preferred value of 5 minutes). Each time the timing module completes a ΔT5 duration, it sends a signal back to the central control module. Upon receiving this signal, the central control module sends a command to the optimal comfort temperature calculation module to recall the optimal comfort temperature. Upon receiving this signal from the central control module, the optimal comfort temperature calculation module sends the first set of optimal comfort temperature values ​​previously stored therein to the comfort temperature calculation module for real-time updates of the calculated comfort temperature and subsequent adjustments to the control strategy.

[0121] The control unit 104 is further configured to determine the perceived temperature based on the optimal comfort temperature, the dry-bulb temperature of the supply air, the relative humidity of the supply air, and the airflow speed of the internal fan. The specific functions and processing of this control unit 104 are described in step S220.

[0122] Specifically, before calculating the perceived temperature, the relationship between the dry-bulb temperature of the supply air and the optimal comfort temperature is determined. If the dry-bulb temperature of the supply air is greater than or equal to the optimal comfort temperature, then the formula for calculating the perceived temperature is:

[0123] T g =T a +14×[exp(0.05×( T aT s )×(RH-RH S ))]-0.03×(T a -T s )×v

[0124] If the dry-bulb temperature of the supplied air is lower than the optimal comfort temperature, then the formula for calculating the perceived temperature is:

[0125] T g =T a -14×[exp(0.05×(T s -T a )×(RH-RH S ))]-0.01×(T s -T a )×v

[0126] In the formula, T gThe perceived temperature is the temperature felt by the body. It reflects the human body's perception of the external thermal environment and is a comprehensive response to the degree of hotness or coldness of the external environment, focusing on comfort from the human perspective. (T) a RH represents the dry-bulb temperature of the supply air, and RH represents the relative humidity of the supply air. s The optimal air humidity can be set to 55%; v represents the airflow speed of the internal fan, calculated from the internal fan speed. An internal fan speed-wind speed correspondence table is pre-stored in the central control module. During actual operation, the central control module retrieves the internal fan speed information, identifies the corresponding wind speed value in the internal fan speed-wind speed correspondence table, and then sends this value to the perceived temperature calculation module for calculation.

[0127] Specifically, after the perceived temperature calculation module receives the optimal comfort temperature value from the optimal comfort temperature calculation module, it will send a set of signals to the central control module. Upon receiving these signals, the central control module will activate the sensor module to complete a data acquisition. Specifically, the sensor module will activate the temperature sensor, humidity sensor, and infrared human body temperature monitor to collect data on the dry-bulb temperature and relative humidity of the air conditioner's supply air, as well as human body temperature parameters within the air conditioner's supply area. If no human body temperature parameters are collected, they will be set to the default value of 37.5℃. Once the perceived temperature module receives the optimal comfort temperature value from the optimal comfort temperature calculation module and the air conditioner's supply air dry-bulb temperature and relative humidity values ​​from the central control module, it will begin calculating the perceived temperature.

[0128] The control unit 104 is further configured to control the operating mode of the air conditioner, the frequency of the compressor, the speed of the indoor fan, and the position of the air guide plate based on the dry-bulb temperature of the supplied air, the optimal comfort temperature, the perceived temperature, and the user's body temperature. The specific functions and processing of this control unit 104 are described in step S230.

[0129] This solution calculates the optimal comfort temperature and perceived temperature, and controls the air conditioner's operating mode and the operating status of the compressor, internal fan, and air guide plate accordingly. This makes the portable air conditioner more comfortable to deliver air, improves its adaptability, and makes the control strategy more tailored to the user's actual needs.

[0130] In some embodiments, the control unit 104 controls the operating mode of the air conditioner, the frequency of the compressor, the speed of the indoor fan, and the position of the air guide plate based on the dry-bulb temperature of the supply air, the optimal comfort temperature, the perceived temperature, and the user's body temperature, including:

For the specific functions and processing of this control unit 104, please refer to step S330.

[0134] The control unit 104 is further configured to, if the difference is within a third range, control the compressor to increase its frequency to a third set frequency, set the internal fan speed to a low speed, and oscillate the air guide plate; and control the compressor frequency based on the dry-bulb temperature of the supplied air, the optimal comfort temperature, and the perceived temperature. The specific functions and processing of this control unit 104 are described in step S340.

[0135] In some embodiments, the control unit 104 controls the frequency of the compressor based on the dry-bulb temperature of the supply air, the optimal comfort temperature, and the perceived temperature, including:

[0136] The control unit 104 is further configured to determine the relationship between the dry-bulb temperature of the supplied air and the optimal comfort temperature, and to determine the relationship between the perceived temperature and the set temperature. The set temperature is the ambient comfort temperature, set to 25°C. For the specific functions and processing of this control unit 104, please refer to step S410.

[0137] The control unit 104 is further configured to control the compressor to increase its frequency at a third set rate if the dry-bulb temperature of the supplied air is lower than the optimal comfort temperature and the perceived temperature is lower than the set temperature. The specific functions and processing of this control unit 104 are described in step S420.

[0138] The control unit 104 is further configured to, if the dry-bulb temperature of the supplied air is lower than the optimal comfort temperature and the perceived temperature is lower than the set temperature, control the compressor to reduce its frequency at a third set rate, and the compressor frequency shall not be lower than the third set frequency.

[0140] The control unit 104 is further configured to, if the difference is within a fifth range, control the air conditioner to operate in heating mode; increase the compressor frequency to a fifth set frequency, and then control the compressor to increase the frequency at a fifth set rate; control the internal fan speed to the highest speed and the air guide vane position to the most favorable airflow position. For the specific functions and processing of this control unit 104, please refer to step S360.

[0141] Specifically, after obtaining three sets of parameters, including the human body temperature Tp, the optimal comfort temperature Ts, and the perceived temperature Tg within the air supply range of the air conditioner, the central control module first executes the judgment strategy to determine the range of the difference between the human body temperature Tp and the standard body temperature "37.5℃", and then determines whether the human body surface temperature is in an overheated or overcooled state, and then determines the corresponding control strategy based on the range. When Tp-37.5℃ ≥ 0.5℃, i.e. the difference is in the first range, comfort control strategy 1 is implemented; when 0.5℃ > Tp-37.5℃ > 0.3℃, i.e. the difference is in the second range, comfort control strategy 2 is implemented; when 0.3℃ ≥ Tp-37.5℃ ≥ -0.3℃, i.e. the difference is in the third range, comfort control strategy 3 is implemented; when -0.3℃ > Tp-37.5℃ ≥ -0.5℃, i.e. the difference is in the fourth range, comfort control strategy 4 is implemented; when -0.5℃ > Tp-37.5℃, i.e. the difference is in the fifth range, comfort control strategy 5 is implemented.

[0142] Comfort control strategy 1 is as follows: The system believes that the human body is in an overheated state under the current conditions. The system selects to execute the cooling command and starts the cooling mode. At this time, the compressor module first executes the frequency increase to the target frequency of 65Hz, and then executes the frequency increase control strategy of 10Hz / min. The indoor fan module executes the high fan speed, and the air guide plate module executes the most favorable air outlet position (i.e., the left and right center position) until the air conditioner outlet temperature reaches the temperature value of "optimal comfort temperature Ts minus 5℃". After that, the dry bulb temperature, relative humidity, and human body temperature are re-acquired to adjust the comfort control strategy until the human body temperature is within the range of comfort.

[0143] Comfort control strategy 2 is as follows: The system assumes that the human body is in a slightly warm state at the current state. The system selects to execute the cooling command and turns on the cooling mode. At this time, the compressor module first executes the frequency increase to the target frequency of 50Hz, and then executes the frequency increase control strategy of 6Hz / min. The indoor fan module executes the medium fan speed, and the air guide plate module executes the most favorable air outlet position, until the air outlet temperature of the air conditioner reaches the temperature value of "optimal comfort temperature Ts minus 2℃". After that, the dry bulb temperature, relative humidity, and human body temperature are re-acquired to adjust the comfort control strategy until the human body temperature is within the range of comfort.

[0144] Comfort control strategy 3 is as follows: the system assumes that the human body is in a neutral state under the current conditions. The compressor module increases the frequency to the target frequency of 30Hz, the internal fan module operates at a low fan speed, the air guide plate module swings left and right, and the compressor frequency is controlled according to the dry bulb temperature of the supplied air, the optimal comfort temperature, and the perceived temperature.

[0145] Specifically, it is determined whether the dry-bulb temperature Ta of the supply air meets the target value of the calculated optimal comfort temperature Ts±1℃, and whether the perceived temperature Tg meets the target value of 25±1℃. When the air conditioner selects to implement comfort control strategy 3, the air conditioner is considered to be in the optimal comfort air supply condition if either of the above two judgment conditions is met during operation. If the dry-bulb temperature Ta of the air conditioner supply air is less than the optimal comfort temperature Ts±1℃ and the perceived temperature Tg is less than 25±1℃, the compressor will operate at a frequency increase control strategy of 3Hz / min until either of the above two judgment conditions is met; if the dry-bulb temperature Ta of the supply air is greater than the optimal comfort temperature Ts±1℃ and the perceived temperature Tg is greater than 25±1℃, the compressor will operate at a frequency decrease control strategy of 3Hz / min, and the compressor's operating frequency will not be lower than 30Hz. If this continues for a duration of △T6 (within the range of 5 to 30 minutes, preferably 20 minutes), the compressor will be shut down.

[0146] Comfort control strategy 4 is as follows: The system assumes that the human body is in a slightly cold state at the current state, so the system selects to execute the heating command and start the heating mode. At this time, the compressor module first executes the frequency increase to the target frequency of 50Hz, and then executes the frequency increase control strategy of 6Hz / min. The indoor fan module executes the medium fan speed, and the air guide plate module executes the most favorable air outlet position, until the air outlet temperature of the air conditioner reaches the temperature value of "optimal comfort temperature Ts plus 2℃". After that, the dry bulb temperature, relative humidity, and human body temperature are re-acquired to adjust the comfort control strategy until the human body temperature is within the range of comfort.

[0147] Comfort control strategy 5 is as follows: If the system determines that the human body is in an overly cold state, the system will execute the heating command and start the heating mode. At this time, the compressor module will first increase the frequency to the target frequency of 65Hz, and then follow the frequency increase control strategy of 10Hz / min. The indoor fan module will run at a high fan speed, and the air guide module will run at the most favorable air outlet position until the air outlet temperature of the air conditioner reaches the temperature value of "optimal comfort temperature Ts plus 5℃". After that, the dry bulb temperature, relative humidity, and human body temperature will be reacquired to adjust the comfort control strategy until the human body temperature is within the range of comfort.

[0149] Step 1: According to control measure 1, execute the self-test mode. Through the joint operation of the compressor module, air guide plate module and internal fan module, obtain the current ambient air dry bulb temperature, relative humidity and human body temperature of the room where the air conditioner is located, so as to facilitate the selection of subsequent control decisions.

[0150] Step 2: Calculate the optimal comfort temperature Ts according to control measure 2. Calculate and obtain the optimal comfort temperature Ts of the current environment of the air conditioner. Use this temperature to determine the formula for calculating the perceived temperature in control measure 3, so as to update the calculated value of the perceived temperature Tg in real time and adjust the subsequent control strategy.

[0151] Step 3: Calculate the perceived temperature Tg according to control measure 3. Calculate the perceived temperature Tg of the current environment of the air conditioner according to the optimal comfort temperature Ts calculated in control measure 2.

[0152] Step 4: Implement the comfort control strategy according to control measure 4. Select a specific comfort control strategy based on the three sets of parameters calculated within the air supply range of the air conditioner: human body temperature Tp, optimal comfort temperature Ts, and perceived temperature Tg.
