In some embodiments, adjusting the target initial opening of the target electronic expansion valve according to the difference between the air inlet temperature information and the air outlet temperature information includes:
under the condition that the air conditioner is judged to be in a constant-temperature dehumidification mode and the difference value between the air inlet temperature information and the air outlet temperature information is larger than a first threshold value, increasing the opening degree of a target electronic expansion valve on the basis of the target initial opening degree according to a first target speed;
specifically, the first threshold described in the embodiment of the present invention is a preset temperature threshold, and is used for regulating and controlling the opening of the target electronic expansion valve when the air conditioner is in the constant temperature dehumidification mode.
Preferably, in this embodiment, the first threshold may be 0.5 ℃.
The first target rate described in the embodiment of the present invention refers to a preset value of the increase rate of the opening degree of the target electronic expansion valve.
Preferably, in the present embodiment, the first target rate may be set to 1 opening/1 second.
In this embodiment, when the user starts the operation of the air conditioner, and selects the constant temperature dehumidification mode, the air conditioner switches to the constant temperature dehumidification mode, at this time, the compressor of the air conditioner is started to operate, the target electronic expansion valve is also simultaneously opened, and the opening degree of the target electronic expansion valve is adjusted to the target initial opening degree, for example, the target initial opening degree is 240 steps.
In this embodiment, when the air conditioner is determined to be in the constant temperature dehumidification mode, the air inlet temperature information and the air outlet temperature information of the indoor unit are obtained, and meanwhile, when it is determined that a difference between the air inlet temperature information T1 and the air outlet temperature information T2 is greater than a first threshold, that is, T1-T2 is greater than 0.5 ℃, that is, when the target electronic expansion valve is at the target initial opening degree, the air inlet temperature is higher than the air outlet temperature, and temperature compensation provided by a capillary tube of the indoor unit for an air outlet airflow through a high-temperature gaseous refrigerant is insufficient, so that the opening degree of the target electronic expansion valve needs to be further increased to increase the flow rate of the high-temperature gaseous refrigerant in the capillary tube.
Further, in this embodiment, according to a first target rate, for example, 1 opening/1 second, on the basis of the target initial opening, the opening of the target electronic expansion valve is gradually increased, the flow rate of the high-temperature gaseous refrigerant in the capillary tube is increased, and the outlet temperature information of the indoor unit and the inlet temperature information are controlled to be consistent.
In some embodiments, when the air conditioner is judged to be in the constant-temperature dehumidification mode and the difference value between the air inlet temperature information and the air outlet temperature information is smaller than a second threshold value, the opening degree of the target electronic expansion valve is reduced on the basis of the target initial opening degree according to a second target speed;
in this embodiment, the second threshold described in the embodiment of the present invention is also a preset temperature threshold, which is also used for controlling the opening degree of the target electronic expansion valve when the air conditioner is in the constant temperature dehumidification mode.
Preferably, in this embodiment, the second threshold may be set to-0.5 ℃.
The second target rate described in the embodiment of the present invention refers to a reduction rate value of the preset target electronic expansion valve opening degree.
Preferably, in the present embodiment, the second target rate may also be set to 1 opening/1 second.
When the air conditioner is judged to be in the constant temperature dehumidification mode, the air inlet temperature information and the air outlet temperature information of the indoor unit are obtained, and meanwhile, under the condition that the difference value between the air inlet temperature information T1 and the air outlet temperature information T2 is smaller than a second threshold value, namely T1-T2 < -0.5. That is, when the target electronic expansion valve is at the target initial opening degree, the temperature of the air inlet is lower than that of the air outlet, and the temperature compensation provided by the capillary tube of the indoor unit for the air flow of the air outlet through the high-temperature gaseous refrigerant is too large, so that the opening degree of the target electronic expansion valve needs to be further reduced to reduce the flow rate of the high-temperature gaseous refrigerant in the capillary tube.
Further, in this embodiment, according to a second target rate, for example, 1 opening/1 second, on the basis of the target initial opening, the opening of the target electronic expansion valve is gradually decreased, and the flow rate of the high-temperature gaseous refrigerant in the capillary tube of the indoor unit is decreased, so as to control the air outlet temperature information of the indoor unit to be consistent with the air inlet temperature information.
In some embodiments, when the air conditioner is judged to be in the constant temperature dehumidification mode and the difference value between the air inlet temperature information and the air outlet temperature information meets a first target threshold range, the opening degree of the target electronic expansion valve is kept as a target initial opening degree; the first target threshold range is determined based on the first threshold and the second threshold.
Specifically, the first target threshold range described in the embodiment of the present invention is determined based on the first threshold value and the second threshold value, and is a threshold range for determining that the opening degree of the target electronic expansion valve is maintained when the air conditioner is in the constant temperature dehumidification mode.
Preferably, in this embodiment, the first target threshold range may take values of-0.5 ℃ to 0.5 ℃, including-0.5 ℃ and 0.5 ℃. That is, when the air conditioner is determined to be in the constant temperature dehumidification mode, and the difference between the air inlet temperature information T1 and the air outlet temperature information T2 satisfies the first target threshold range, that is, it is determined that the temperature of 0.5 ≧ T1-T2 ≧ -0.5 ℃, that is, when the target electronic expansion valve is at the target initial opening degree, the air inlet temperature and the air outlet temperature are at the same level, and the temperature compensation provided by the capillary tube of the indoor unit to the air outlet airflow through the high-temperature gaseous refrigerant is appropriate, so that the opening degree of the target electronic expansion valve does not need to be regulated and controlled, and therefore, the opening degree of the target electronic expansion valve can be continuously maintained as the target initial opening degree, that is, the opening degree of the target electronic expansion valve can be maintained to be unchanged at 240 steps.
According to the method provided by the embodiment of the invention, under the scene that the air conditioner is in the constant-temperature dehumidification mode, the difference value between the air inlet temperature information and the air outlet temperature information of the indoor unit is obtained, and whether the opening degree of the target electronic expansion valve needs to be regulated and controlled is judged based on the first target threshold range, so that the flow of high-temperature gaseous refrigerants in the capillary tube of the indoor unit can be effectively controlled, the air inlet temperature and the air outlet temperature of the indoor unit are ensured to be always consistent, and the high-quality indoor constant-temperature dehumidification effect is realized.
In some embodiments, opening the target electronic expansion valve, and adjusting the opening degree of the target electronic expansion valve to a target initial opening degree, includes:
under the condition that the air conditioner is judged not to be in the constant-temperature dehumidification mode, the current preset mode is kept to operate, and indoor temperature information and indoor humidity information are obtained;
and under the condition that the indoor temperature information is lower than the target temperature threshold value and the indoor humidity information is higher than the first humidity threshold value, opening the target electronic expansion valve, and adjusting the opening degree of the target electronic expansion valve to be the target initial opening degree.
Specifically, the target temperature threshold described in the embodiment of the present invention refers to a preset temperature threshold, which is used for comparing with the detected indoor temperature to determine whether to open the target electronic expansion valve when the air conditioner is not in the constant temperature dehumidification mode.
Preferably, in the present embodiment, the target temperature threshold may be 26 ℃.
The first humidity threshold described in the embodiment of the present invention refers to a preset humidity threshold, which is used for comparing with the detected indoor humidity to determine whether to open the target electronic expansion valve when the air conditioner is not in the constant temperature dehumidification mode; the humidity range is determined according to the comfortable humidity range of the human body surface, wherein the humidity range of the human body surface comfort is 45-65%.
Preferably, in the present embodiment, the first humidity threshold may be 70%.
The fact that the air conditioner is not in the constant-temperature dehumidification mode described in the embodiment of the invention means that when a user selects a common mode to operate a refrigeration or dehumidification function, the air conditioner is in a preset mode, namely, an operation mode corresponding to the refrigeration or dehumidification function.
Further, in this embodiment, when it is determined that the air conditioner is not in the constant temperature dehumidification mode, the current preset mode is maintained to continue operating, and meanwhile, the indoor temperature information and the indoor humidity information are respectively obtained through a temperature sensor and a humidity sensor in the indoor unit;
and under the condition that the indoor temperature information is lower than a target temperature threshold value, such as 26 ℃, and the indoor humidity information is higher than a first humidity threshold value, such as 70%, opening the target electronic expansion valve, adjusting the opening degree of the target electronic expansion valve to be a target initial opening degree, and performing indoor constant-temperature dehumidification treatment.
According to the method provided by the embodiment of the invention, under the scene that a user selects a common mode to operate a refrigeration or dehumidification function and the air conditioner is not in a constant temperature dehumidification mode, the target electronic expansion valve is started under the condition of meeting the preset temperature and humidity by monitoring the indoor temperature and humidity in real time, so that the air conditioner can perform constant temperature dehumidification, the effects of large-amount dehumidification and small-amount cooling can be realized under the condition that the user selects the common mode, and the comfort and the use experience of the user are improved.
In some embodiments, when it is determined that the air conditioner is not in the constant temperature dehumidification mode, and when the indoor temperature information is lower than the target temperature threshold and the indoor humidity information is higher than the first humidity threshold, the method adjusts and controls the target initial opening of the target electronic expansion valve according to a difference between the air inlet temperature information and the air outlet temperature information, further includes:
under the condition that the difference value between the air inlet temperature information and the air outlet temperature information is larger than a third threshold value, increasing the opening degree of the target electronic expansion valve on the basis of the target initial opening degree according to a first target speed;
specifically, the third threshold described in the embodiment of the present invention is a preset temperature threshold, and is used for regulating and controlling the opening of the target electronic expansion valve when the air conditioner is not in the constant temperature dehumidification mode.
Preferably, in this embodiment, the third threshold may be 10 ℃.
In this embodiment, when it is determined that the indoor temperature information is lower than the target temperature threshold of 26 ℃ and the indoor humidity information is higher than the first humidity threshold of 70%, the target electronic expansion valve is opened, and after the opening degree of the target electronic expansion valve is adjusted to the target initial opening degree, the temperature sensor of the indoor unit is used to obtain the air inlet temperature information T1 and the air outlet temperature information T2, if the difference between T1 and T2 is greater than the third threshold, that is, T1-T2 is greater than 10 ℃, that is, at this time, the target electronic expansion valve is at the target initial opening degree, the air inlet temperature is far higher than the air outlet temperature, temperature compensation provided by the capillary tube of the indoor unit for the air flow of the air outlet through the high-temperature gaseous refrigerant is insufficient, and therefore, the opening degree of the target electronic expansion valve needs to be further increased to increase the flow rate of the high-temperature gaseous refrigerant in the capillary tube.
Further, in this embodiment, according to a first target rate, for example, 1 opening/1 second, on the basis of 240 steps of the target initial opening, the opening of the target electronic expansion valve is gradually increased, the flow rate of the high-temperature gaseous refrigerant in the capillary tube is increased, and the temperature difference between the air outlet temperature information and the air inlet temperature information of the indoor unit is controlled within an acceptable range, so as to avoid discomfort on the body surface of the user due to an excessive temperature difference.
In some embodiments, in the case that the difference between the air inlet temperature information and the air outlet temperature information is smaller than the fourth threshold, the opening degree of the target electronic expansion valve is decreased on the basis of the target initial opening degree at the second target rate;
specifically, the fourth threshold described in the embodiment of the present invention is also a preset temperature threshold, and is also used for regulating and controlling the opening degree of the target electronic expansion valve when the air conditioner is not in the constant temperature dehumidification mode.
Preferably, in this embodiment, the fourth threshold may be 8 ℃.
In the present embodiment, similarly, when it is determined that the air conditioner is not in the constant temperature dehumidification mode of operation, it is determined that the indoor temperature information is lower than the target temperature threshold value by 26 c, and when the indoor humidity information is higher than the first humidity threshold value by 70%, opening the target electronic expansion valve, adjusting the opening degree of the target electronic expansion valve to the target initial opening degree, acquiring air inlet temperature information T1 and air outlet temperature information T2 through a temperature sensor of the indoor unit, if the difference value between T1 and T2 is smaller than a fourth threshold value, i.e., T1-T2 < 8 deg.c, that is, when the target electronic expansion valve is at the target initial opening degree, in the general trend of temperature variation, the temperature of the air outlet is higher than that of the air inlet, the temperature of the air outlet needs to be reduced as much as possible, therefore, the flow rate of the high-temperature gaseous refrigerant in the capillary tube of the indoor unit can be controlled and reduced by further reducing the opening degree of the target electronic expansion valve.
Further, in this embodiment, according to a second target rate, for example, 1 opening/1 second, on the basis of the target initial opening 240 steps, the opening of the target electronic expansion valve is gradually reduced, and the flow rate of the high-temperature gaseous refrigerant in the capillary tube is reduced, so that the temperature difference between the air outlet temperature information and the air inlet temperature information of the indoor unit is controlled within an acceptable range, and discomfort on the body surface of the user due to an excessive temperature difference is avoided.
In some embodiments, in a case that the difference between the air inlet temperature information and the air outlet temperature information satisfies a second target threshold range, the opening degree of the target electronic expansion valve is maintained as a target initial opening degree; the second target threshold range is determined based on the third threshold and the fourth threshold.
Specifically, the second target threshold range described in the embodiment of the present invention is determined based on the third threshold and the fourth threshold, and is a threshold range for determining to maintain the opening degree of the target electronic expansion valve when the air conditioner is not in the constant temperature dehumidification mode.
Preferably, in this embodiment, the first target threshold range may take on a value of 8 ℃ to 10 ℃, including 8 ℃ and 10 ℃. That is, when it is judged that the air conditioner is not in the constant temperature dehumidification mode, it is judged that the indoor temperature information is lower than the target temperature threshold value of 26 c, and when the indoor humidity information is higher than the first humidity threshold value by 70%, opening the target electronic expansion valve, adjusting the opening degree of the target electronic expansion valve to the target initial opening degree, acquiring air inlet temperature information T1 and air outlet temperature information T2 through a temperature sensor of the indoor unit, if the difference between T1 and T2 meets a second target threshold range, namely, the temperature is not less than 10 ℃ and not less than T1-T2 and not less than 8 ℃, namely, when the target electronic expansion valve is at the target initial opening degree, the temperature difference between the air inlet temperature and the air outlet temperature is between 8 ℃ and 10 ℃, the opening degree of a target electronic expansion valve is not required to be regulated, the opening degree of the target electronic expansion valve may be continuously maintained at the target initial opening degree, that is, the opening degree of the target electronic expansion valve may be maintained at 240 steps.
According to the method provided by the embodiment of the invention, under the scene that the air conditioner is not in the constant-temperature dehumidification mode but in the normal mode of refrigeration or dehumidification function operation, the difference value between the air inlet temperature information and the air outlet temperature information of the indoor unit is obtained, and whether the opening degree of the target electronic expansion valve needs to be regulated and controlled is judged based on the second target threshold range, so that the flow of high-temperature gaseous refrigerants in the capillary tube of the indoor unit can be effectively controlled, the air inlet temperature and the air outlet temperature of the indoor unit are prevented from being too large in temperature difference and are within an acceptable range, the effects of large-amount dehumidification and small-amount cooling are realized, and the use experience of a user is favorably improved.

Preferably, in the present embodiment, the second humidity threshold may be 55%.
That is, in this embodiment, after determining that the air conditioner is not in the constant temperature dehumidification mode, the target electronic expansion valve is opened, the target initial opening degree of the target electronic expansion valve is controlled, after performing constant temperature dehumidification on the room, the control device controls the humidity sensor of the indoor unit to continuously detect the indoor humidity information, and after determining that the indoor humidity drops to 55%, the control device automatically closes the target electronic expansion valve, and switches the operation mode of the air conditioner back to the previous preset mode.
