Description

Technical Field

[0001] This invention relates to the field of air conditioning, and in particular to a control method for an air conditioner, a machine-readable storage medium, and an air conditioner. Background Technology

[0002] In modern air conditioning systems, indoor ambient temperature sensors play a crucial role. They are responsible for monitoring the indoor temperature in real time and feeding this information back to the air conditioning system's control center. Based on the data provided by the sensor, the control center adjusts the air conditioner's output power to meet the user's cooling / heating needs.

[0003] However, when the indoor ambient temperature sensor malfunctions, the air conditioning system cannot accurately obtain indoor temperature information, and therefore cannot precisely control the air conditioning compressor. To protect the system from further damage, the air conditioning system usually chooses to stop the operation of the air conditioning compressor. While this measure avoids potential risks, it also means that users cannot use the air conditioner when they need cooling or heating.

[0004] Furthermore, while current air conditioning systems can detect sensor malfunctions and issue alarms, they often lack a rapid and effective troubleshooting mechanism. Users need to wait for repair personnel to arrive and inspect the system, which not only consumes a significant amount of time and effort but may also result in prolonged periods of unusable air conditioning due to lengthy repair times. Summary of the Invention

[0005] One objective of this invention is to maintain the normal operation of the air conditioner when the indoor ambient temperature sensor malfunctions, thereby avoiding inconvenience to users due to shutdown.

[0006] A further objective of this invention is to avoid energy waste caused by excessive cooling and to ensure the stability and comfort of indoor ambient temperature.

[0007] Specifically, according to a first aspect of the present invention, the present invention provides a control method for an air conditioner, comprising:

[0008] The cooling / heating mode of the air conditioner is determined by combining the outdoor ambient temperature and the user's set temperature.

[0009] In cooling mode, the target temperature of the indoor coil is set to the preset first temperature value;

[0010] The compressor is controlled based on the first temperature value to achieve rapid cooling of the indoor environment;

[0011] Update the target temperature of the indoor coil to the desired second temperature value;

[0012] The compressor is controlled based on the second temperature value to maintain the real-time temperature of the indoor coil at the second temperature value, thereby ensuring that the indoor ambient temperature is close to the user's set temperature.

[0013] Optionally, after the step of controlling the compressor operation based on the first temperature value, the method further includes:

[0014] A first operating time is set according to the outdoor ambient temperature, and the first operating time is proportional to the outdoor ambient temperature;

[0015] After the first running time, the step of updating the target temperature of the indoor coil to the desired second temperature value is executed.

[0016] Optionally, the step of updating the target temperature of the indoor coil to a desired second temperature value includes:

[0017] The desired second temperature value is obtained by subtracting the corresponding coil temperature compensation constant from the user's set temperature.

[0018] The target temperature of the indoor coil is changed from the first temperature value to the second temperature value.

[0019] Optionally, the first temperature value ranges from 11℃ to 17℃; and

[0020] The value range of the coil temperature compensation constant is 0℃~10℃.

[0021] Optionally, after determining the cooling / heating mode of the air conditioner by combining the outdoor ambient temperature and the user's set temperature, the method further includes:

[0022] In heating mode, the target temperature of the indoor coil is set to the preset third temperature value;

[0023] The compressor is controlled based on the third temperature value to achieve rapid heating of the indoor environment;

[0024] Update the target temperature of the indoor coil to the desired fourth temperature value;

[0025] The compressor is controlled based on the fourth temperature value to maintain the real-time temperature of the indoor coil at the fourth temperature value, thereby ensuring that the indoor ambient temperature is close to the user's set temperature.

[0026] Optionally, after the step of controlling the compressor operation based on the third temperature value, the method further includes:

[0027] A second operating time is set based on the outdoor ambient temperature, and the second operating time is inversely proportional to the outdoor ambient temperature;

[0028] After the second running time, the step of updating the target temperature of the indoor coil to the desired third temperature value is executed.

[0029] Optionally, the step of updating the target temperature of the indoor coil to the desired fourth temperature value includes:

[0030] The desired fourth temperature value is obtained by adding the corresponding coil temperature compensation constant to the user's set temperature.

[0031] The target temperature of the indoor coil is changed from the third temperature value to the fourth temperature value.

[0032] Optionally, the third temperature value ranges from 45℃ to 60℃; and

[0033] The value range of the coil temperature compensation constant is 0℃~10℃.

[0034] According to a second aspect of the present invention, a machine-readable storage medium is provided thereon storing a machine-executable program that, when executed by a processor, implements the control method described in any one of the preceding descriptions.

[0035] According to a third aspect of the present invention, an air conditioner is provided, comprising:

[0036] The indoor unit is equipped with an indoor ambient temperature sensor and an indoor coil temperature sensor.

[0037] The outdoor unit, which is communicatively connected to the indoor unit, is equipped with an outdoor ambient temperature sensor; and

[0038] A controller includes a memory, a processor, and a machine-executable program stored in the memory and running on the processor, wherein when the processor executes the machine-executable program, it implements the control method described in any one of the preceding descriptions.

[0039] The air conditioner control method of this invention intelligently selects the cooling / heating mode of the air conditioner based on the outdoor ambient temperature and the user's set temperature. For example, in cooling mode, the target temperature of the indoor coil is first set to a preset first temperature value. Then, the compressor is controlled to operate based on the first temperature value to achieve rapid cooling of the indoor environment, bringing an immediate cool feeling to the user. Next, the target temperature of the indoor coil is updated to a desired second temperature value, and the compressor is controlled to operate again based on the second temperature value, maintaining the real-time temperature of the indoor coil at the second temperature value. This ensures that the indoor ambient temperature is close to the user's set temperature, creating a comfortable and stable indoor environment for the user. Thus, when the indoor ambient temperature sensor malfunctions, the air conditioner can continue to operate normally by relying on the temperature control logic described above, using a method of rapid cooling followed by slow cooling, instead of relying on the data provided by the faulty sensor. This not only avoids air conditioner shutdown due to indoor ambient temperature sensor malfunction but also ensures the continuity and stability of indoor temperature control, providing users with an uninterrupted comfortable experience.

[0040] Furthermore, the air conditioner control method of the present invention, after controlling the compressor operation based on a first temperature value, also sets a first operating time according to the outdoor ambient temperature. This first operating time is proportional to the outdoor ambient temperature, meaning that in hotter weather conditions, the air conditioner is given a longer rapid cooling phase, allowing the indoor ambient temperature to drop quickly. After the first operating time, the target temperature of the indoor coil is updated to the desired second temperature value. This transition marks the shift from a rapid cooling phase to a refined cooling phase, where the air conditioner begins to maintain the indoor ambient temperature in a more energy-efficient and stable manner. This not only effectively avoids energy waste caused by over-cooling but also ensures the stability and comfort of the indoor environment.

Therefore, the invention is intended to cover such modifications and variations within the scope of the appended claims and their equivalents.

When a feature "includes or contains" one or more of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may be further included.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0052] The present invention provides a control method for an air conditioner 10, which is a split-type air conditioner 10, including an indoor unit 110 and an outdoor unit 120. The indoor unit 110 and the outdoor unit 120 work together to provide a comfortable indoor environment for the user.

[0053] This invention provides a control method for an air conditioner 10. Figure 1 This is a schematic flowchart of a control method for an air conditioner 10 according to an embodiment of the present invention, as shown below. Figure 1 As shown, the control method includes at least the following steps S102 to S110.

[0054] Step S102: Determine the cooling / heating mode of the air conditioner 10 by combining the outdoor ambient temperature and the user's set temperature.

[0055] In this step, the air conditioner 10 reads the outdoor ambient temperature data and the user's set temperature data. Based on this data, the air conditioner 10 intelligently determines whether to execute the cooling mode or the heating mode. For example, when the outdoor ambient temperature is high and the user's set temperature is low, the air conditioner 10 will execute the cooling mode; conversely, when the outdoor ambient temperature is low and the user's set temperature is high, the air conditioner 10 will execute the heating mode.

[0056] Step S104: In cooling mode, set the target temperature of the indoor coil to a preset first temperature value.

[0057] In this step, once the cooling mode is determined, the air conditioner 10 will use a preset first temperature value as the target temperature for the indoor coil. The first temperature value is relatively low, usually lower than the user's final desired indoor ambient temperature, and also lower than the actual temperature of the indoor coil when the indoor ambient temperature reaches the user's set temperature. The purpose is to control the air conditioner 10 to operate with a larger cooling capacity in the initial stage of cooling, thereby causing the indoor temperature to drop rapidly.

[0058] Step S106: Based on the first temperature value, control the compressor 122 to operate, so as to achieve rapid cooling of the indoor environment.

[0059] In this step, the air conditioner 10 adjusts the operating status of the compressor 122 based on the difference between the actual temperature of the indoor coil and the first temperature value. If the actual temperature is higher than the first temperature value, the compressor 122 will operate at a higher power / frequency to quickly reduce the coil temperature and achieve rapid cooling of the indoor environment.

[0060] Step S108: Update the target temperature of the indoor coil to the desired second temperature value.

[0061] In this step, the second temperature value refers to the indoor ambient temperature being relatively close to the user's set temperature when the actual temperature of the indoor coil is maintained at this value during the operation of the compressor 122. The second temperature value can be predicted based on the cooling capacity of the air conditioner 10, the heat load of the indoor environment, and the user's set temperature.

[0062] Step S110: Based on the second temperature value, control the compressor 122 to operate, so that the real-time temperature of the indoor coil is maintained at the second temperature value, so as to ensure that the indoor ambient temperature is close to the user's set temperature.

[0063] In this step, the air conditioner 10 further adjusts the operating status of the compressor 122 based on the difference between the actual temperature of the indoor coil and the second temperature value. If the actual temperature is lower than the second temperature value, the compressor 122 will appropriately reduce its power / frequency; if the actual temperature is higher than the second temperature value, the compressor 122 will appropriately increase its power / frequency. This process continues until the temperature of the indoor coil stabilizes near the second temperature value, thereby ensuring that the indoor ambient temperature is close to the user's set temperature.

[0064] Using the control method of the air conditioner 10 in this embodiment, when the indoor ambient temperature sensor 111 malfunctions, the air conditioner 10 can no longer rely on the data provided by the malfunctioning sensor, but instead rely on the temperature control logic described above. In cooling mode, the air conditioner 10 continues to operate normally by first rapidly cooling and then slowly cooling. This not only avoids air conditioner shutdown due to the malfunction of the indoor ambient temperature sensor 111, but also ensures the continuity and stability of indoor temperature control, providing users with an uninterrupted comfortable experience.

[0065] It is understandable that outdoor ambient temperature is one of the important factors affecting the cooling effect of air conditioner 10. If the outdoor ambient temperature is high, air conditioner 10 will need more time to lower the indoor ambient temperature because the outdoor heat load is greater. Conversely, if the outdoor ambient temperature is low, air conditioner 10 can bring the indoor ambient temperature to the user's set temperature more quickly.

[0066] Therefore, after controlling the compressor 122 to operate based on the first temperature value, a first operating time can be set according to the outdoor ambient temperature, and the first operating time is proportional to the outdoor ambient temperature. After the first operating time, the target temperature of the indoor coil is updated to the desired second temperature value.

[0067] The initial operating time is directly proportional to the outdoor ambient temperature. This means that when the outdoor ambient temperature is high, the initial operating time will be extended accordingly to ensure that the air conditioner 10 has enough time to quickly cool the indoor environment. Conversely, when the outdoor ambient temperature is low, the initial operating time will be shortened accordingly to save energy and improve cooling efficiency.

[0068] It's worth noting that after the first run, regardless of whether the actual temperature of the indoor coil has reached the first temperature value, the air conditioner 10 will update the target temperature of the indoor coil to the second temperature value. This transition marks the shift from rapid cooling to refined cooling, with the air conditioner 10 beginning to maintain the indoor ambient temperature in a more energy-efficient and stable manner. This not only effectively avoids energy waste caused by over-cooling but also ensures the stability and comfort of the indoor environment.

[0069] By incorporating the outdoor ambient temperature to rationally set the first operating time, the control strategy of the air conditioner 10 can be made more intelligent, meeting user needs while minimizing energy waste and unnecessary operating costs.

[0070] In an optional embodiment, the step of updating the target temperature of the indoor coil to the desired second temperature value may be: first, subtracting the corresponding coil temperature compensation constant from the user's set temperature to obtain the desired second temperature value, and then changing the target temperature of the indoor coil from the first temperature value to the second temperature value.

[0071] Specifically, the coil temperature compensation constant can be pre-stored in the relevant storage medium of the air conditioner 10. Different set temperatures correspond to different coil temperature compensation constants because the heat load and cooling capacity of the air conditioner 10 will change as the set temperature changes. Therefore, in order to maintain the stability and accuracy of the indoor ambient temperature, the coil temperature compensation constant needs to be adjusted to adapt to these changes.

[0072] After the user sets the temperature via remote control or other means, the air conditioner 10 will look up the corresponding coil temperature compensation constant based on this set temperature. This process can be achieved through table lookup or interpolation algorithms to ensure that the coil temperature compensation constant matching the set temperature is found quickly and accurately.

[0073] In cooling mode, in order to effectively absorb heat from the indoor air, the temperature of the indoor coil must be lower than the indoor ambient temperature. Therefore, the air conditioner 10 subtracts the corresponding coil temperature compensation constant from the user's set temperature to obtain a lower temperature value, namely the desired second temperature value.

[0074] Once the second temperature value is determined, the air conditioner 10 will change the target temperature of the indoor coil from the current first temperature value to this new second temperature value, and control the compressor 122 accordingly to keep the indoor ambient temperature stable near the user's set temperature.

[0075] In this embodiment, the range of the first temperature value can be 11℃ to 17℃, such as 11℃, 12℃, 13℃, 14℃, 15℃, 16℃, 17℃, etc. Preferably, the first temperature value can be 14℃. 14℃ serves as an intermediate value, satisfying the need for rapid cooling without causing the air conditioner to operate under high load for an extended period.

[0076] The value range of the coil temperature compensation constant can be 0℃ to 10℃, such as 0℃, 1℃, 2℃, 3℃, 4℃, 5℃, 6℃, 7℃, 8℃, 9℃, 10℃, etc. Generally speaking, the lower the user's set temperature, the lower the value of the coil temperature compensation constant. For example, when the set temperature is 26℃, the indoor coil temperature compensation constant can be 10℃, and when the set temperature is 24℃, the indoor coil temperature compensation constant can be 7℃. Specifically, the correspondence between the user's set temperature and the coil temperature compensation constant can be set specifically based on the overall performance of the air conditioner 10 and user preferences.

[0077] Figure 2 This is a schematic flowchart of a control method for an air conditioner 10 according to another embodiment of the present invention, such as... Figure 2 As shown, the control method includes at least the following steps S202 to S210.

[0078] Step S202: Determine the cooling / heating mode of the air conditioner 10 by combining the outdoor ambient temperature and the user's set temperature.

[0079] In this step, the air conditioner 10 reads the outdoor ambient temperature data and the user's set temperature data. Based on this data, the air conditioner 10 intelligently determines whether to execute the cooling mode or the heating mode. For example, when the outdoor ambient temperature is high and the user's set temperature is low, the air conditioner 10 will execute the cooling mode; conversely, when the outdoor ambient temperature is low and the user's set temperature is high, the air conditioner 10 will execute the heating mode.

[0080] Step S204: In heating mode, set the target temperature of the indoor coil to the preset third temperature value.

[0081] In this step, once the heating mode is determined, the air conditioner 10 will use a preset third temperature value as the target temperature for the indoor coil. The third temperature value is relatively high, usually higher than the user's final desired indoor ambient temperature, and also higher than the actual temperature of the indoor coil when the indoor ambient temperature reaches the user's set temperature. The purpose is to control the air conditioner 10 to operate with a larger heating capacity in the early stage of heating, so that the indoor temperature rises rapidly.

[0082] In step S206, the compressor 122 is controlled to operate based on the third temperature value in order to achieve rapid heating of the indoor environment.

[0083] In this step, the air conditioner 10 adjusts the operating status of the compressor 122 based on the difference between the actual temperature of the indoor coil and the third temperature value. If the actual temperature is lower than the third temperature value, the compressor 122 will operate at a higher power / frequency to quickly increase the coil temperature and achieve rapid heating of the indoor environment.

[0084] Step S208: Update the target temperature of the indoor coil to the desired fourth temperature value.

[0085] In this step, the fourth temperature value refers to the indoor ambient temperature being relatively close to the user's set temperature when the actual temperature of the indoor coil is maintained at this value during the operation of the compressor 122. The fourth temperature value can be predicted based on the cooling capacity of the air conditioner 10, the cooling load of the indoor environment, and the user's set temperature.

[0086] Step S210: Based on the fourth temperature value, control the compressor 122 to operate, so that the real-time temperature of the indoor coil is maintained at the fourth temperature value, so as to ensure that the indoor ambient temperature is close to the user's set temperature.

[0087] In this step, the air conditioner 10 further adjusts the operating status of the compressor 122 based on the difference between the actual temperature of the indoor coil and the fourth temperature value. If the actual temperature is lower than the fourth temperature value, the compressor 122 will appropriately increase its power / frequency; if the actual temperature is higher than the second temperature value, the compressor 122 will appropriately decrease its power / frequency. This process continues until the temperature of the indoor coil stabilizes near the second temperature value, thereby ensuring that the indoor ambient temperature is close to the user's set temperature.

[0088] Using the control method of the air conditioner 10 in this embodiment, when the indoor ambient temperature sensor 111 malfunctions, the air conditioner 10 can no longer rely on the data provided by the malfunctioning sensor, but instead rely on the temperature control logic described above. In heating mode, the air conditioner 10 continues to operate normally by first rapidly heating and then slowly heating. This not only avoids air conditioner shutdown due to the malfunction of the indoor ambient temperature sensor 111, but also ensures the continuity and stability of indoor temperature control, providing users with an uninterrupted comfortable experience.

[0089] It is understandable that outdoor ambient temperature is one of the important factors affecting the heating performance of air conditioner 10. If the outdoor ambient temperature is low, air conditioner 10 will need more time to raise the indoor ambient temperature because the outdoor cooling load is greater. Conversely, if the outdoor ambient temperature is high, air conditioner 10 can bring the indoor ambient temperature to the user's set temperature more quickly.

[0090] Therefore, after controlling the compressor 122 to operate based on the third temperature value, a second operating time can be set according to the outdoor ambient temperature. The second operating time is inversely proportional to the outdoor ambient temperature. After the second operating time, the target temperature of the indoor coil is updated to the desired third temperature value.

[0091] The second operating time is inversely proportional to the outdoor ambient temperature. This means that when the outdoor ambient temperature is low, the second operating time will be extended accordingly to ensure that the air conditioner 10 has enough time to quickly heat up the indoor environment. Conversely, when the outdoor ambient temperature is high, the second operating time will be shortened accordingly to save energy and improve heating efficiency.

[0092] It's worth noting that after the second running period ends, regardless of whether the actual temperature of the indoor coil has reached the third temperature value, the air conditioner 10 will update the target temperature of the indoor coil to the fourth temperature value. This transition marks the shift from rapid heating to refined heating, with the air conditioner 10 beginning to maintain the indoor ambient temperature in a more energy-efficient and stable manner. This not only effectively avoids energy waste caused by excessive heating but also ensures the stability and comfort of the indoor environment.

[0093] By incorporating the outdoor ambient temperature to rationally set the second operating time, the control strategy of the air conditioner 10 can be made more intelligent, meeting user needs while minimizing energy waste and unnecessary operating costs.

[0094] In an optional embodiment, the step of updating the target temperature of the indoor coil to the desired fourth temperature value may be: first, adding the corresponding coil temperature compensation constant to the user's set temperature as the desired fourth temperature value, and then changing the target temperature of the indoor coil from the third temperature value to the fourth temperature value.

[0095] Specifically, the coil temperature compensation constant can be pre-stored in the relevant storage medium of the air conditioner 10. Different set temperatures correspond to different coil temperature compensation constants because the heat load and cooling capacity of the air conditioner 10 will change as the set temperature changes. Therefore, in order to maintain the stability and accuracy of the indoor ambient temperature, the coil temperature compensation constant needs to be adjusted to adapt to these changes.

[0096] After the user sets the temperature via remote control or other means, the air conditioner 10 will look up the corresponding coil temperature compensation constant based on this set temperature. This process can be achieved through table lookup or interpolation algorithms to ensure that the coil temperature compensation constant matching the set temperature is found quickly and accurately.

[0097] In heating mode, in order to effectively absorb cooling energy from the indoor air, the temperature of the indoor coil must be higher than the indoor ambient temperature. Therefore, the air conditioner 10 adds a corresponding coil temperature compensation constant to the user's set temperature to obtain a higher temperature value, namely the desired fourth temperature value.

[0098] Once the fourth temperature value is determined, the air conditioner 10 will change the target temperature of the indoor coil from the current third temperature value to this new fourth temperature value, and control the compressor 122 accordingly to keep the indoor ambient temperature stable near the user's set temperature.

[0099] In this embodiment, the range of the third temperature value can be 45℃ to 60℃, such as 45℃, 48℃, 50℃, 52℃, 55℃, 60℃, etc. Preferably, the third temperature value can be 50℃. 50℃ serves as an intermediate value, satisfying the need for rapid heating without causing the air conditioner to operate under high load for an extended period.

[0100] Similarly, the value range of the coil temperature compensation constant can be 0℃ to 10℃, such as 0℃, 1℃, 2℃, 3℃, 4℃, 5℃, 6℃, 7℃, 8℃, 9℃, 10℃, etc. Generally speaking, the higher the user's set temperature, the higher the value of the coil temperature compensation constant. For example, when the set temperature is 35℃, the indoor coil temperature compensation constant can be 10℃, and when the set temperature is 30℃, the indoor coil temperature compensation constant can be 8℃. Specifically, the correspondence between the user's set temperature and the coil temperature compensation constant can be set specifically based on the overall performance of the air conditioner 10 and the user's preferences.

[0101] The control method of this invention not only ensures the stable operation and efficient cooling / heating effect of the air conditioner 10, but also provides users with a more comfortable and energy-saving indoor environment experience through intelligent control strategies. When the indoor ambient temperature sensor 111 malfunctions, the air conditioner 10 can continue to operate based on the temperature control logic of this invention, avoiding shutdown of the air conditioner 10 due to sensor failure and ensuring the continuity and stability of indoor ambient temperature regulation.

Figure 4 As shown, this embodiment of the invention also provides an air conditioner 10. The air conditioner 10 includes at least an indoor unit 110, an outdoor unit 120, and a controller 130.

[0106] The indoor unit 110 is equipped with an indoor ambient temperature sensor 111 and an indoor coil temperature sensor 112. The outdoor unit 120 is communicatively connected to the indoor unit 110 and is equipped with an outdoor ambient temperature sensor 121. The controller 130 includes a memory 131 and a processor 132.
