[0003] A control method for an air conditioner in a high-temperature and low-humidity environment is disclosed in the related technology. The air conditioner is equipped with a dry-bulb temperature sensing device at the air inlet. The control method for the air conditioner in a high-temperature and low-humidity environment includes: acquiring the relative humidity of the indoor environment; when the relative humidity is less than or equal to a preset humidity threshold, acquiring the dry-bulb temperature detected by the dry-bulb temperature sensing device; when the dry-bulb temperature is greater than or equal to a first preset temperature, acquiring the coil temperature of the evaporator; and controlling the cooling capacity of the air conditioner based on the dry-bulb temperature and the coil temperature so that the dry-bulb temperature is lower than the first preset temperature.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] While the above methods can regulate humidity in air conditioners, they require reducing the compressor's operating frequency to decrease refrigerant flow, which in turn affects the air conditioner's temperature control capabilities, leading to significant fluctuations in indoor temperature and poor temperature stability.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a control method and control device for an air conditioner, an air conditioner, and a storage medium to improve the stability of the air conditioner's temperature regulation.

[0012] Optionally, the state of the on / off device is controlled according to the target number of operations, including: acquiring human characteristic information of indoor personnel; determining the target heat exchange zone to perform dehumidification operation based on the human characteristic information and the target number of operations; and controlling the opening degree of the on / off device corresponding to the target heat exchange zone.

[0013] Optionally, controlling the opening degree of the on / off device corresponding to the target heat exchange zone includes: determining a target adjustment scheme for the on / off device based on the temperature difference and operating status; and adjusting the opening degree of the on / off device corresponding to the target heat exchange zone according to the target adjustment scheme.

[0014] Optionally, the above control method further includes: determining the target frequency of the compressor based on the temperature difference and operating status; and controlling the compressor to operate at the target frequency.

[0015] Optionally, when a heat exchange zone needs to be shut down, the method further includes: controlling the shut-off device corresponding to the heat exchange zone to be shut down to close; and controlling the outflow end of the heat exchange zone to close when the shut-off device's closing time reaches a time threshold.

[0016] In some embodiments, the control device includes a processor and a memory storing program instructions, the processor being configured to execute the control method for an air conditioner when the program instructions are executed.

[0017] In some embodiments, the air conditioner includes: a product body; an indoor heat exchanger having multiple heat exchange zones, the inflow end of which is connected to the refrigerant circulation loop of the air conditioner via a pipe assembly module; wherein each heat exchange zone is connected to the pipe assembly module via a corresponding on / off device; and a control device for the air conditioner as described above, which is installed on the product body.

[0019] The control method and control device for an air conditioner, the air conditioner, and the storage medium provided in this disclosure can achieve the following technical effects:

[0020] Based on the air conditioner's operating status, it is determined whether different operations are required for each heat exchange zone. If the air conditioner is operating in its preset state, it is assumed that different operations are necessary for each heat exchange zone. In this case, the ambient temperature and the air conditioner's target temperature are obtained. Based on these values, the required refrigerant amount for each heat exchange zone is determined, and the refrigerant distribution to each zone is adjusted accordingly. This effectively avoids large temperature fluctuations caused by the air conditioner simultaneously performing dehumidification and temperature adjustment operations, thus improving the stability of the air conditioner's temperature regulation.

[0035] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0036] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0037] In this embodiment of the disclosure, the terminal device refers to an electronic device with wireless connectivity. The terminal device can communicate with the aforementioned smart home appliances by connecting to the internet, or directly via Bluetooth, WiFi, or other methods. In some embodiments, the terminal device may be, for example, a mobile device, a computer, or an in-vehicle device built into a hovercraft, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, or any combination thereof. Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0038] This disclosure provides an air conditioner including an indoor heat exchanger with multiple heat exchange zones. The inlet end of the indoor heat exchanger is connected to the refrigerant circulation loop of the air conditioner via a pipe assembly module. Each heat exchange zone is connected to the pipe assembly module via a corresponding on / off device. The air conditioner also includes a processor electrically connected to each on / off device for controlling the opening degree of each on / off device and the operating status of components such as the compressor and fan. In the case where the indoor unit of the air conditioner is wall-mounted, such as... Figure 4 As shown, the indoor heat exchanger 10 is mainly divided into three parts. The windward side has a larger airflow, while the leeward side has a smaller airflow. Through a flow-diversion design, the heat exchanger 10 is grouped into several hairpin tubes, forming different heat exchange zones 11. It should be noted that the size of each heat exchange zone 11 can be the same or different depending on its location; the specific dimensions depend on the actual situation and are not specifically limited here. Furthermore, when the indoor unit is a cabinet type, the indoor heat exchanger is either flat or curved. Similar to the zoning setup of wall-mounted indoor units, the indoor heat exchanger is divided into zones through flow diversion. Each heat exchange zone has an individual on / off device such as an electronic expansion valve or solenoid valve to control the refrigerant flow within that zone.

[0039] Combination Figure 1 As shown, this disclosure provides a control method for an air conditioner, including:

[0040] S01, the processor obtains the operating status of the air conditioner.

[0041] S02, under the preset operating state of the air conditioner, the processor obtains the ambient temperature value and the target temperature value of the air conditioner.

[0042] S03, the processor adjusts the refrigerant distribution of each heat exchange zone according to the ambient temperature value and the target temperature value.

[0043] The control method for air conditioners provided in this disclosure can effectively improve the stability of air conditioner temperature regulation. Based on the operating state of the air conditioner, it is determined whether different operations are required for each heat exchange zone. Under the preset operating state of the air conditioner, it is considered that different operations may be required for each heat exchange zone. At this time, the ambient temperature value and the target temperature value of the air conditioner are acquired. Based on the ambient temperature value and the target temperature value, the required amount of refrigerant for each heat exchange zone is determined, and the refrigerant distribution of each heat exchange zone is adjusted. This effectively avoids large temperature fluctuations during temperature regulation caused by the air conditioner simultaneously performing dehumidification and temperature adjustment operations, thereby improving the stability of the air conditioner's temperature regulation.

[0044] Optionally, the preset operating states of the air conditioner include the air conditioner operating in dehumidification mode; or, the air conditioner operating in both cooling and dehumidification modes simultaneously.

[0045] This allows for better and more reasonable adjustment of the refrigerant flow in each heat exchange zone according to the different operating requirements of the air conditioner. This ensures that the air conditioner operates in a manner that meets user needs while avoiding significant fluctuations in indoor temperature. As shown in Table 1, the dehumidification modes include a first dehumidification mode, a second dehumidification mode, and a third dehumidification mode.

[0046] Optionally, the processor adjusts the refrigerant distribution to each heat exchange zone based on the ambient temperature and the target temperature, including: the processor calculating the temperature difference between the target temperature and the ambient temperature; the processor determining the target number of heat exchange zones to perform dehumidification operation corresponding to the operating state based on the temperature difference; and the processor controlling the state of the on / off device based on the target number of operations.

[0047] This allows for a better assessment of the temperature difference between the target temperature and the ambient temperature to determine the desired temperature control effect of the air conditioner, thereby determining the target number of heat exchange zones to operate during dehumidification. Based on the target number, the status of a corresponding number of on / off devices is controlled to input the required amount of refrigerant for dehumidification. This balances the dehumidification and cooling operations of the air conditioner. It should be noted that if humidity adjustment is not required, the target number of heat exchange zones operating during dehumidification can be zero. In this case, the heat exchange zones operating during cooling can be all or only a portion of them; the specific number of heat exchange zones operating during cooling is determined by the actual temperature control requirements.

[0048] Optionally, the processor controls the state of the on / off device based on the target number of operations, including: the processor acquiring the anthropometric information of people in the room; the processor determining the target heat exchange zone to perform dehumidification operation based on the anthropometric information and the target number of operations; and the processor controlling the opening degree of the on / off device corresponding to the target heat exchange zone.

[0049] This allows for better adjustment of the air conditioner's operation based on the actual situation of the people in the room. The air conditioner can determine the identity of the occupants based on their anatomy and then retrieve corresponding parameters to further determine the target heat exchange zone for dehumidification. Alternatively, it can compare the collected anatomy information with big data to determine relevant parameters and further identify the target heat exchange zone for dehumidification. This allows for precise location of the target heat exchange zone for dehumidification, enabling accurate adjustment of the corresponding on / off devices. For example, if the occupant is determined to be elderly, the heat exchange zone that directly blows air onto the user's location can be selected as the target for dehumidification. Or, if the occupant is determined to be a female homeowner, her usual usage habits (showing temperatures close to natural wind) can be used to dynamically select the heat exchange zone at the air outlet as the target for dehumidification. Alternatively, if the occupant is confirmed to be male, his daily habits can be reviewed to show that he exercises in the living room at certain intervals. In this case, the air outlet can be directed towards an open area in the living room, and the heat exchange zone at the location of the air outlet can be selected as the target heat exchange zone for cooling operation. Or, if it is determined that the occupant is sweating profusely, the air outlet can be directed towards the location of the occupant, and the heat exchange zone at the location of the air outlet can be selected as the target heat exchange zone for dehumidification operation, etc.

[0050] Optionally, the processor controls the opening degree of the on / off device corresponding to the target heat exchange zone, including: the processor determining a target adjustment scheme for the on / off device based on the temperature difference and operating status; and the processor adjusting the opening degree of the on / off device corresponding to the target heat exchange zone according to the target adjustment scheme.

[0051] This allows for a better determination of the refrigerant quantity required for each heat exchange zone, based on the desired temperature and dehumidification effects of the air conditioner and the specific location of the target heat exchange zone for cooling operation. This enables the determination of the target opening value for the on / off devices corresponding to each heat exchange zone, and thus the determination of the target adjustment scheme for these devices. Based on the target adjustment scheme, the opening degree of the on / off devices corresponding to the target heat exchange zone is adjusted. The specific opening degree adjustment process is shown in Table 1.

[0052] Combination Figure 2 As shown, this disclosure provides another control method for an air conditioner, including:

[0053] S01, the processor obtains the operating status of the air conditioner.

[0054] S02, under the preset operating state of the air conditioner, the processor obtains the ambient temperature value and the target temperature value of the air conditioner.

[0055] S031, the processor calculates the temperature difference between the target temperature value and the ambient temperature value.

[0056] S032, the processor determines the target frequency of the compressor based on the temperature difference and operating status.

[0057] S033, the processor controls the compressor to run at the target frequency.

[0058] The control method for air conditioners provided in this disclosure can determine the compressor's operating frequency based on the actual temperature and dehumidification requirements of the air conditioner, thereby avoiding unnecessary energy consumption. The total amount of refrigerant required by the air conditioner is determined based on the temperature difference between the target temperature and the ambient temperature, as well as the air conditioner's operating status. The compressor's operating frequency, i.e., the target frequency, is then determined based on the required total refrigerant amount, and the compressor is controlled to operate at the target frequency. The specific adjustment process of the compressor frequency is shown in Table 1.

[0059] Table 1

[0060]

[0061]

[0062] The first dehumidification mode is the conventional dehumidification mode in the current air conditioning industry. The evaporator operates in the corresponding state of conventional dehumidification, the compressor runs at a low frequency, and the fan runs at a low speed, providing some cooling effect, but it is not significant. The second dehumidification mode balances cooling effect with some dehumidification capacity, and is often used in scenarios with high humidity and temperature control requirements. In this mode, the compressor frequency is appropriately increased compared to the first dehumidification mode, and the fan speed is positively correlated with the compressor frequency. The third dehumidification mode balances dehumidification effect with some temperature control capability, and is often used in scenarios with excessive humidity and temperature control requirements. In this mode, the compressor frequency is even higher than in the second dehumidification mode to ensure dehumidification efficiency and meet temperature control needs. Furthermore, the fan speed is also increased accordingly, and is still positively correlated with the compressor frequency. It should be specifically noted that when operating in the second or third dehumidification mode, the fan speed increment corresponding to the heat exchange zone performing the cooling operation should be greater than or equal to the fan speed increment corresponding to the heat exchange zone performing the dehumidification operation, in order to ensure the temperature regulation efficiency of the air conditioner as much as possible. Furthermore, the compressor operating frequencies in the above parameters are in the order N1 < N2 < N3 < N4. The opening degree of the on / off device is in the order K1 < K2 < K3 < K4. The first quantity can be any value within [45, 55]% of the total number of heat exchange zones in the air conditioner, preferably 46%, 50%, or 52%. The second quantity can be any value within [70, 80]% of the total number of heat exchange zones in the air conditioner, preferably 72%, 75%, or 78%.

[0063] Combination Figure 3 As shown, this disclosure provides another control method for an air conditioner, including:

[0064] S01, the processor obtains the operating status of the air conditioner.

[0065] S02, under the preset operating state of the air conditioner, the processor obtains the ambient temperature value and the target temperature value of the air conditioner.

[0066] S03, the processor adjusts the refrigerant distribution of each heat exchange zone according to the ambient temperature value and the target temperature value.

[0067] S041, when a heat exchange zone needs to be shut down, the processor controls the on / off device corresponding to the heat exchange zone to be shut down to close.

[0068] S042, when the closing time of the on / off device reaches the time threshold, the processor controls the outflow end of the heat exchange zone to close.

[0069] The control method for air conditioners provided in this disclosure effectively avoids insufficient refrigerant utilization due to refrigerant residue in the heat exchange zone. Therefore, when a heat exchange zone needs to be closed, its corresponding on / off device is controlled to close. When the closing time of the on / off device reaches a time threshold, it is considered that all refrigerant in the heat exchange zone has flowed out. At this time, the outflow end of the heat exchange zone is closed. This effectively ensures that there is no refrigerant residue in the heat exchange zone. Furthermore, compared to using sensor detection, this solution is less expensive.

[0070] Combination Figure 5 As shown, this disclosure provides a control device for an air conditioner, including a processor 301 and a memory 302. Optionally, the device may further include a communication interface 303 and a bus 304. The processor 301, communication interface 303, and memory 302 can communicate with each other via the bus 304.

The processor 301 executes functional applications and data processing by running the program instructions / modules stored in the memory 302, thereby implementing the control method for the air conditioner in the above embodiments.
