Example one
An embodiment of the present application provides a control method of an air conditioner compressor, as shown in fig. 1, the control method includes:
in the embodiment of the present invention, the "in the dehumidification mode of the air conditioner" may indicate a state where the air conditioner is operated in the dehumidification mode, or may indicate a state from when the air conditioner receives a dehumidification command to when the air conditioner exits the dehumidification mode. The dew point temperature of return air refers to the temperature at which the air is cooled to saturation under the condition that the water vapor content in the air is unchanged and the air pressure is kept constant. The low-pressure saturation temperature refers to a temperature at which the liquid and the vapor are in a dynamic equilibrium state, i.e., a saturation state, in a low-pressure environment.
In step 11, the real-time return air dew point temperature during the operation of the air conditioner can be obtained as follows: and respectively detecting the real-time return air dry bulb temperature and the real-time return air wet bulb temperature of the inner fan, and calculating the real-time return air dew point temperature when the air conditioner operates according to the return air dry bulb temperature and the return air wet bulb temperature. Or, the return air temperature and humidity sensor can be triggered to acquire the return air dew point temperature in real time. Meanwhile, the real-time low-pressure saturation temperature is calculated by data measured by a low-pressure gauge arranged in the air conditioning system, and can also be obtained by looking up a table by the measured data. The real-time return air dew point temperature and the real-time low-pressure saturation temperature can be obtained by the return air temperature and humidity sensor and the temperature detection device in a wired or wireless mode, and the return air dew point temperature and the low-pressure saturation temperature are obtained by detection, and are not limited here.
wherein the control logic is associated with the real-time return air dew point temperature and the real-time low pressure saturation temperature. In the embodiment of the application, the return air dew point temperature and the low-pressure saturation temperature are used as control parameters in advance, and corresponding control actions are set to form the control logic.
In an application scenario, the controlling the output of the air conditioner compressor according to the real-time return air dew point temperature, the real-time low-pressure saturation temperature and a preset control logic includes:
and when the real-time low-pressure saturation temperature is not less than the real-time return air dew point temperature, controlling the air conditioner to increase the output quantity of the air conditioner compressor until the real-time low-pressure saturation temperature is less than the real-time return air dew point temperature.
Specifically, the controlling the air conditioner to increase the output of the air conditioner compressor until the real-time low-pressure saturation temperature is lower than the real-time return air dew point temperature may include:
controlling the air conditioner to gradually increase the output of the air conditioner compressor by a first step value until the real-time low-pressure saturation temperature is lower than the real-time return air dew point temperature, wherein the first step value is N percent of a preset output, where N is a preset value, and a value of N may be set according to an actual requirement (for example, may be set to 5, 10, etc.), which is not limited herein. Specifically, the preset value N may be dynamically valued according to a difference between the return air dew point and the real-time low-pressure saturation temperature. Specifically, when the difference between the return air dew point and the real-time low-pressure saturation temperature is large, the preset value N may be set to a large value for rapid adjustment, and when the difference between the return air dew point and the real-time low-pressure saturation temperature is small, the preset value N may be set to a small value for relatively slow adjustment. Further, when the preset value N is dynamically adjusted, the value N can be dynamically adjusted by adjusting the value N and the time for maintaining the value N. Specifically, the dynamic adjustment of the N value can be performed by setting a "small step fast walking" mode and a "large step slow running" mode. The small-step fast-walking mode means that when the difference value between the return air dew point and the real-time low-pressure saturation temperature is small, a small adjustment step length can be set, the time for maintaining each adjustment is short, the small-step fast-walking adjustment is carried out, and whether the control is stopped or not is judged in time so as to avoid excessive adjustment; the "jogging" mode means that when the difference between the return air dew point and the real-time low-pressure saturation temperature is large, a large adjustment step length can be set, the adjustment of the "jogging" can be performed for a long time each time the adjustment is maintained, and the adjustment frequency can be reduced. The dynamic adjustment of the value of N can also be set to be adjusted in a manner of "small step and multiple step" or "large step and few step". Specifically, the "small step and multiple step" manner means that, when the total required humidity adjustment amount is constant, the N value takes a relatively small value, and the N value is adjusted multiple times within a certain time, so as to complete the total required humidity adjustment amount. The "large step and small step" manner means that the N value takes a relatively large value under the condition that the total required humidity adjustment amount is constant, and the N value is adjusted by a small amount within a certain time, thereby completing the total required humidity adjustment amount. The preset output is an output set value of the air conditioner compressor in the dehumidification mode of the air conditioner, and the output set value may be set before the air conditioner is shipped.
Further, the controlling the air conditioner to gradually increase the output of the air conditioner compressor by a first step value until the real-time low-pressure saturation temperature is less than the real-time return air dew point temperature may further include:
when the real-time low-pressure saturation temperature is lower than the real-time return air dew point temperature, gradually reducing the output quantity of the air conditioner compressor by a second step value until the real-time low-pressure saturation temperature is not lower than the real-time return air dew point temperature;
controlling the output quantity of the air conditioner compressor to increase the second step value;
wherein the first step value is greater than the second step value.
In another application scenario, the control method further includes:
under the dehumidification mode of the air conditioner, acquiring a real-time environment humidity value when the air conditioner operates;
and when the real-time environment humidity value is lower than a preset humidity value, ending the dehumidification mode of the air conditioner.
Specifically, the above-mentioned real-time ambient humidity value when obtaining the air conditioner operation can be obtained by setting a humidity sensor. The humidity sensor may be a lithium chloride humidity sensor, an alumina humidity sensor, a ceramic humidity sensor, or the like, which can achieve the real-time environment humidity value obtaining function, and is not limited herein.
It should be noted that the above application scenarios are only exemplary, and besides the above application scenarios, other control logics related to the return air dew point temperature and the low pressure saturation temperature may also be set in the embodiments of the present application, which is not limited herein.
Specifically, the above controlling the output of the air-conditioning compressor specifically comprises: and controlling the air conditioner to increase or decrease the rotating speed of the air conditioner compressor so as to control the output quantity of the air conditioner compressor. Alternatively, the above-mentioned controlling the output quantity of the air-conditioner compressor may be: and controlling the air conditioner to increase or decrease the frequency of the air conditioner compressor so as to control the output quantity of the air conditioner compressor.
Therefore, the control method in the embodiment of the application obtains the real-time return air dew point temperature and the real-time low-pressure saturation temperature when the air conditioner operates; and controlling the output quantity of the air conditioner compressor according to the real-time return air dew point temperature, the real-time low-pressure saturation temperature and a preset control logic. Because return air dew point temperature and low pressure saturation temperature can reflect the humiture of air conditioner place environment to a certain extent, consequently, control method in this application embodiment makes the air conditioner can carry out nimble control to the air conditioner compressor according to the actual conditions of environment at the dehumidification in-process, is favorable to making the more reasonable operation of air conditioner under the dehumidification mode.

specifically, step 22 may refer to the description of step 11 in the embodiment shown in fig. 1, and is not described herein again.
in this embodiment of the present application, when it is determined that the real-time low-pressure saturation temperature obtained in step 22 is not less than the real-time return air dew point temperature, the air conditioner may be controlled to gradually increase the output of the air conditioner compressor by a preset first step value by increasing the rotation speed, frequency, or other manners of the air conditioner. For example, let the output of the air conditioner compressor be YaThe set value of the output quantity of the air conditioner compressor is YbThe first step value is Yb10 percent (i.e., 10% Y)b) Then in step 24, the output of the air conditioner compressor is increased to Ya+10％*YbAnd then returns to step 22.

Meanwhile, the real-time low-pressure saturation temperature is calculated by data measured by a low-pressure gauge arranged in the air conditioning system, and can also be obtained by looking up a table by the measured data. The real-time return air dew point temperature and the real-time low-pressure saturation temperature can be obtained by the return air temperature and humidity sensor in a wired or wireless mode, and the return air dew point temperature detected by the return air temperature and humidity sensor is not limited herein.
The control module 42 is used for controlling the output of the air-conditioning compressor according to the real-time return air dew-point temperature, the real-time low-pressure saturation temperature and a preset control logic;
wherein, the control module 42 further includes: a first processing unit (not shown), which may be configured to: and when the real-time low-pressure saturation temperature is not less than the real-time return air dew point temperature, controlling the air conditioner to increase the output quantity of the air conditioner compressor until the real-time low-pressure saturation temperature is less than the real-time return air dew point temperature.
Wherein, the controlling the air conditioner to increase the output of the air conditioner compressor until the real-time low-pressure saturation temperature is less than the real-time return air dew point temperature comprises:

Specifically, the preset value N may be dynamically valued according to a difference between the return air dew point and the real-time low-pressure saturation temperature. Specifically, when the difference between the return air dew point and the real-time low-pressure saturation temperature is large, the preset value N may be set to a large value for rapid adjustment, and when the difference between the return air dew point and the real-time low-pressure saturation temperature is small, the preset value N may be set to a small value for relatively slow adjustment. Further, when the preset value N is dynamically adjusted, the value N can be dynamically adjusted by adjusting the value N and the time for maintaining the value N. Specifically, the dynamic adjustment of the N value can be performed by setting a "small step fast walking" mode and a "large step slow running" mode. The small-step fast-walking mode means that when the difference value between the return air dew point and the real-time low-pressure saturation temperature is small, a small adjustment step length can be set, the time for maintaining each adjustment is short, the small-step fast-walking adjustment is carried out, and whether the control is stopped or not is judged in time so as to avoid excessive adjustment; the 'jogging with big step' mode means that when the difference value between the return air dew point and the real-time low-pressure saturation temperature is large, a large adjusting step length can be set, the adjusting time of the 'jogging with big step' is long each time of adjustment, and the adjusting frequency can be effectively reduced. The dynamic adjustment of the value of N can also be set to be adjusted in a manner of "small step and multiple step" or "large step and few step". Specifically, the "small step and multiple step" manner means that, when the total required humidity adjustment amount is constant, the N value takes a relatively small value, and the N value is adjusted multiple times within a certain time, so as to complete the total required humidity adjustment amount. The "large step and small step" manner means that the N value takes a relatively large value under the condition that the total required humidity adjustment amount is constant, and the N value is adjusted by a small amount within a certain time, thereby completing the total required humidity adjustment amount. The preset output is an output set value of the air conditioner compressor in the dehumidification mode of the air conditioner, and the output set value may be set before the air conditioner is shipped.
Further, the control module 42 may further include: a second processing unit (not shown in the figures) operable to:
when the real-time low-pressure saturation temperature is lower than the real-time return air dew point temperature, gradually reducing the output quantity of the air conditioner compressor by a second step value until the real-time low-pressure saturation temperature is not lower than the real-time return air dew point temperature;

the control module further comprises: a third processing unit (not shown in the figures) that can be used to: and when the real-time environment humidity value is lower than a preset humidity value, ending the dehumidification mode of the air conditioner.
Specifically, the above-mentioned real-time ambient humidity value when obtaining the air conditioner operation can be obtained by setting a humidity sensor. The humidity sensor may be a lithium chloride humidity sensor, an alumina humidity sensor, a ceramic humidity sensor, or the like, which can achieve the real-time environment humidity value obtaining function, and is not limited herein.
Specifically, the above controlling the output of the air-conditioning compressor specifically comprises: and controlling the air conditioner to increase or decrease the rotating speed of the air conditioner compressor so as to control the output quantity of the air conditioner compressor. Alternatively, the above-mentioned controlling the output quantity of the air-conditioner compressor may be: and controlling the air conditioner to increase or decrease the frequency of the air conditioner compressor so as to control the output quantity of the air conditioner compressor.
