Attached Figure Description

[0049] Figure 1 This is a flowchart illustrating the steps of a dehumidification control method for an air conditioner according to some embodiments of the present invention. Detailed Implementation

[0050] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0051] See Figure 1 This embodiment provides a dehumidification control method for an air conditioner, the control method including:

[0052] S100: In dehumidification mode, acquire the outer ring temperature, inner ring temperature and set temperature;

[0053] S200: Controls the indoor unit's fan speed and the on / off state of the electric heater based on the outer ring temperature, inner ring temperature, and set temperature.

[0054] It should be noted that in this embodiment, the dehumidification mode is manually switched in by the user. The user can control the air conditioner to enter the dehumidification mode by sending a signal through the remote control or mobile phone. The control method of the present invention is applied to the cooling mode. In this embodiment, the electric heating is located at the air outlet of the indoor unit of the air conditioner, and heats the air blown out by the indoor unit by turning on the power.

[0055] Furthermore, in S100, when the air conditioner enters dehumidification mode, the air conditioner detects and acquires the outer ring temperature, inner ring temperature, and set temperature; where the outer ring temperature refers to the outdoor ambient temperature, which is detected and acquired by the temperature sensor located on the outdoor unit of the air conditioner; the inner ring temperature is the indoor ambient temperature, which is detected and acquired by the temperature sensor located on the indoor unit of the air conditioner; the set temperature is the target temperature set by the user, and the air conditioner needs to cool to reach the set temperature.

[0056] Furthermore, in S200, the indoor unit fan speed and the on / off state of the electric heater are controlled based on the outer ring temperature, inner ring temperature, and set temperature. Existing heat pump air conditioners typically use a normal cooling mode for dehumidification, without considering user scenarios or comfort levels. When indoor cooling demand is low, activating the dehumidification mode can easily lead to excessively low perceived temperature, reducing user comfort. In this embodiment, the indoor unit fan speed is increased or decreased based on the outer ring temperature, inner ring temperature, and set temperature, while the electric heater is activated or deactivated. When indoor cooling demand is high, the indoor unit fan speed can be increased, and the electric heater can be deactivated to quickly meet the cooling requirement. When indoor cooling demand is low, the indoor unit fan speed can be appropriately decreased, and the electric heater can be activated. In this case, after the indoor air undergoes heat exchange and dehumidification in the indoor unit, it is heated by the electric heater before being blown out, achieving an isothermal dehumidification effect.

[0057] Understandably, the solution in this embodiment effectively improves the user's comfort experience in dehumidification mode without increasing costs; the solution in this embodiment is simple to control and highly reliable.

[0058] Further, in one specific embodiment, S200 includes:

[0059] S210: Subtract the set temperature from the inner ring temperature to determine the target temperature difference;

[0060] S220: Compare the outer ring temperature with the first temperature threshold.

[0061] S230: When the outer ring temperature is less than the first temperature threshold, the indoor unit fan speed is controlled to switch between the first fan speed, the second fan speed and the third fan speed according to the target temperature difference, and the electric heating is controlled to turn on and off.

[0062] S240: When the outer ring temperature is greater than or equal to the first temperature threshold, control the indoor unit fan speed to the third fan speed and control the electric heating to turn off;

[0063] Among them, the first wind speed < the second wind speed < the third wind speed.

[0064] Preferably, the first temperature threshold is 33 degrees Celsius.

[0065] It should be noted that the higher the indoor unit's fan speed, the higher the indoor air heat exchange efficiency and the better the dehumidification effect.

[0066] Furthermore, in S230, when the outer ring temperature is less than the first temperature threshold, it indicates that the air conditioner load is low. At this time, the indoor unit fan speed can be further controlled according to the target temperature difference, that is, the indoor unit fan speed can be controlled according to a more accurate indoor cooling demand. When the target temperature difference is large, it indicates that the indoor cooling demand is large, and when the target temperature difference is small, it indicates that the indoor cooling demand is small. At the same time, when the outer ring temperature is less than the first temperature threshold, it indicates that the air conditioner load is relatively low. Electric heating can be turned on to improve the user's comfort experience. Since the indoor cooling demand is relatively small at this time, turning on electric heating will not affect the air conditioner's cooling.

[0067] Furthermore, in S240, when the outer ring temperature is greater than or equal to the first temperature threshold, it indicates that the air conditioner load is high, that is, the indoor cooling demand is large. At this time, it is necessary to turn off the electric heating and control the indoor unit fan speed to the third fan speed to increase the air conditioner's cooling efficiency and dehumidification efficiency.

[0068] Understandably, the solution in this embodiment performs preliminary control of the electric heating and indoor unit fan speed based on the outer ring temperature, effectively increasing the accuracy and efficiency of the control method of the present invention.

[0069] Further, in one specific embodiment, S230 includes:

[0070] S231: Obtain the number of people indoors and determine the temperature range into which the target temperature difference falls;

[0071] S232: When the target temperature difference falls into the first temperature range A1, the indoor unit fan speed and the on / off state of the electric heater are controlled according to the number of people in the room.

[0072] S233: When the target temperature difference falls into the second temperature range A2, the indoor unit fan speed and the on / off state of the electric heater are controlled according to the number of people in the room;

[0073] S234: When the target temperature difference falls into the third temperature range A3, the inner plate temperature is obtained, and the indoor unit fan speed, compressor frequency, outdoor fan speed and electric heating are controlled according to the number of people in the room and the inner plate temperature, and the electric heating is turned on.

[0074] S235: When the target temperature difference falls into the fourth temperature range A4, control the indoor unit fan speed to the third fan speed and control the electric heating to turn off.

[0075] Among them, the right endpoint value of A1 is less than or equal to the left endpoint value of A2, the right endpoint value of A2 is less than or equal to the left endpoint value of A3, and the right endpoint value of A3 is less than or equal to the left endpoint value of A4.

[0076] Preferably, the right endpoint value of A1 is -1 degrees Celsius, the right endpoint value of A2 is 2 degrees Celsius, and the right endpoint value of A3 is 5 degrees Celsius.

[0077] Furthermore, in S232, when the target temperature difference falls into the first temperature range A1, it indicates that the indoor temperature is low. At this time, the number of people in the room can be obtained, and the indoor unit fan speed and the start / stop of electric heating can be controlled according to the number of people in the room.

[0078] At this time, the indoor unit fan speed is set to the lowest setting. The lower fan speed ensures normal dehumidification, while the electric heating is turned on to ensure the delivery of hot air and improve the user's comfort experience.

[0079] Furthermore, in S233, when the target temperature difference falls into the second temperature range A2, the number of people in the room can be obtained, and the indoor unit fan speed and the start / stop of electric heating can be controlled according to the number of people in the room.

[0080] Furthermore, in S234, when the target temperature difference falls into the third temperature range A3, it indicates that there is a certain indoor cooling demand. At this time, the number of people in the room and the inner panel temperature can be obtained. Based on the number of people in the room and the inner panel temperature, the indoor unit fan speed, compressor frequency and outdoor fan speed are controlled, while the electric heating is turned on to ensure comfortable air supply.

[0081] Furthermore, in S235, when the target temperature difference falls into the fourth temperature range A4, it indicates that the indoor temperature is high and the indoor cooling demand is large. At this time, it is necessary to increase the indoor unit fan speed to the highest third fan speed and turn off the electric heating to prioritize meeting the indoor cooling demand.

[0082] Understandably, the solution in this embodiment implements different control schemes for different target temperature differences, further improving the reliability of the control method of the present invention.

[0083] Furthermore, in one specific embodiment, S234 includes:

[0084] S236: Compare the number of people indoors with the first threshold;

[0085] S237: When the number of people indoors is less than or equal to the first threshold, control the indoor unit's fan speed to the second fan speed and control the electric heating to turn on;

[0086] S238: When the number of people indoors exceeds the first threshold, the indoor unit fan speed, compressor frequency, outdoor fan speed, and electric heating on / off are controlled according to the inner panel temperature.

[0087] Preferably, the first threshold value is 3.

[0088] Furthermore, in S237, when the number of people indoors is less than or equal to the first threshold, it indicates that there are fewer people indoors compared to when there are more people indoors. At this time, the indoor cooling demand is relatively small, and the indoor unit fan speed can be controlled to the second fan speed for dehumidification.

[0089] Furthermore, in S238, when the number of people indoors exceeds the first threshold, it indicates that there are many people indoors at this time. At this time, it is necessary to focus on meeting the indoor cooling demand. At this time, it is necessary to determine whether the cooling efficiency of the air conditioner needs to be increased based on the inner coil temperature, that is, the indoor unit coil temperature.

[0090] Understandably, the solution in this embodiment has different control schemes for different numbers of people indoors, which further improves the efficiency of the control method of the present invention and the user's comfort experience.

[0091] Furthermore, S232 includes:

[0092] Compare the number of people indoors with the first threshold.

[0093] When the number of people indoors is less than or equal to the first threshold, the indoor unit's fan speed is controlled to the first fan speed, and the electric heating is turned on.

[0094] When the number of people indoors exceeds the first threshold, the indoor unit's fan speed is set to the first speed, and the electric heating is turned off.

[0095] Understandably, when the target temperature difference falls within the first temperature range A1, it indicates that the indoor temperature is low. In this case, the indoor unit's fan speed should be set to the first speed for dehumidification. However, excessively high fan speeds would lower the indoor temperature too much, affecting the comfort of the occupants. When the number of occupants is less than or equal to the first threshold, it indicates that there are fewer occupants. Compared to situations with more occupants, the indoor cooling demand is lower. In this case, the electric heater can be turned on to deliver hot air and raise the room temperature, thus improving the comfort of the occupants. When the number of occupants is greater than the first threshold, it indicates that there are more occupants and a greater indoor cooling demand. In this case, it is necessary to prioritize meeting the indoor cooling needs. In this case, the electric heater should be turned off to prevent it from raising the indoor temperature too much and affecting the comfort of the occupants.

[0096] Furthermore, S233 includes:

[0097] Compare the number of people indoors with the first threshold.

[0098] When the number of people indoors is less than or equal to the first threshold, the indoor unit's fan speed is controlled to the first fan speed, and the electric heating is turned on.

[0099] When the number of people indoors exceeds the first threshold, the indoor unit's fan speed is controlled to the second speed, and the electric heating is turned on.

[0100] Understandably, when the target temperature difference falls within the second temperature range A2, it indicates that the indoor temperature is close to the set temperature and is relatively comfortable. When the number of people in the room is less than or equal to the first threshold, it indicates that there are fewer people in the room. Compared to when there are more people in the room, the indoor cooling demand is relatively small. At this time, the indoor unit fan speed is controlled at the first speed, and the electric heating is turned on to deliver hot air to raise the room temperature and improve the comfort of the people in the room. When the number of people in the room is greater than the first threshold, it indicates that there are more people in the room and the indoor cooling demand is greater. At this time, it is necessary to focus on meeting the indoor cooling demand. At this time, the indoor unit fan speed is controlled at the second speed, and the electric heating is turned on. By increasing the indoor unit fan speed, the increased indoor cooling demand caused by the increase in the number of people in the room can be met. The medium fan speed and the electric heating working together can basically achieve a similar effect to isothermal dehumidification.

[0101] Further, in one specific embodiment, S238 includes:

[0102] When the temperature of the inner plate exceeds the second temperature threshold, the compressor frequency and the speed of the outdoor fan are increased, the indoor unit fan speed is controlled to the second fan speed, and the electric heating is turned off.

[0103] When the temperature of the inner plate is less than or equal to the second temperature threshold, the indoor unit fan speed is controlled to the second fan speed, and the electric heating is turned on.

[0104] Preferably, the second temperature threshold is 18 degrees Celsius.

[0105] In this embodiment, when the inner panel temperature is greater than the second temperature threshold, it indicates that the overall temperature of the heat exchanger of the indoor unit of the air conditioner is high and the cooling efficiency of the indoor unit is low. At this time, the compressor frequency and the outdoor fan speed can be increased to improve the heat exchange efficiency of the air conditioner. At the same time, the indoor unit fan speed is controlled to the second fan speed, and the electric heating is turned off to avoid the electric heating affecting the cooling efficiency of the air conditioner. When the inner panel temperature is less than or equal to the second temperature threshold, it indicates that the overall temperature of the heat exchanger of the indoor unit is low and the cooling efficiency of the indoor unit is high. At this time, only the indoor unit fan speed is controlled to the second fan speed and the electric heating is turned on to improve the comfort experience of the indoor users.

[0106] Understandably, the solution in this embodiment provides a more refined and accurate control method for different inner panel temperatures when there are many people indoors, effectively improving the accuracy and reliability of the control method of the present invention, and further enhancing the user's comfort experience.

[0107] Furthermore, in one specific embodiment, prior to S100, the control method further includes:

[0108] When the air conditioner first enters the dehumidification mode, the indoor unit fan speed is controlled to the first fan speed and maintained for the first time threshold before the S100 step is executed.

[0109] Preferably, the first time threshold is 5 minutes.

[0110] Understandably, when the air conditioner is turned on and enters dehumidification mode for the first time, controlling the indoor unit's fan speed to a low speed and maintaining it for the first time threshold before executing step S100 can ensure the accuracy of detecting and obtaining the outer and inner ring temperatures.

[0111] Furthermore, in one specific embodiment, after S200, the control method further includes:

[0112] S300: Exit dehumidification mode after executing the second time threshold of S200.

[0113] Preferably, the second time threshold is 5 minutes.

[0114] In this embodiment, the device operates in dehumidification mode, and judges conditions such as outer ring temperature, inner ring temperature, set temperature, number of people in the room, and inner panel temperature in real time. Based on the real-time data, it controls the indoor unit fan speed and the on / off of electric heating. After the second time threshold of the dehumidification mode is reached, the dehumidification mode is exited.

[0115] Understandably, the solution in this embodiment can control the air conditioner to automatically exit the dehumidification mode, reducing the tediousness of manual operation for users and further improving the user's comfort experience.

[0116] Furthermore, this embodiment provides a control device for an air conditioner, the control device including:

[0117] The detection module is used to acquire the outer ring temperature, inner ring temperature and set temperature in dehumidification mode.

[0118] The control module is used to control the indoor unit's fan speed and the activation of the electric heater based on the outer ring temperature, inner ring temperature, and set temperature.
