The corresponding relation between the preset temperature and the target temperature and humidity can be preserved in advance, namely, for each preset temperature, a plurality of human bodies can be tested, the most comfortable temperature and humidity of the corresponding human body can be obtained, the th temperature and humidity of a plurality of human body collected samples corresponding to the set somatosensory comfort level can be obtained in the set area of the preset temperature, the target temperature and humidity range corresponding to the preset temperature can be determined according to the th temperature and humidity, and the corresponding relation can be preserved, for example, the preset temperature is 25 degrees, at the moment, the th temperature is 23.5-27 degrees, the th humidity is 40-60% of the relative humidity, most users can feel most comfortable, therefore, the th temperature and humidity are all contained in the temperature range of 23.5-27 degrees, the relative humidity is 40-60%, the temperature of 23.5-27 degrees and the humidity of 40-60% can be determined, the target temperature and the corresponding relation between the preset temperature of 25 degrees and the target temperature of 23.5-27 degrees and the humidity of 40-60% can be preserved.
Thus, the corresponding relationship between the stored preset temperature and the target temperature and humidity range can be as shown in table 1:
| preset temperature | Target temperature and humidity range |
| 30° | The temperature is 28-30.5 percent, and the humidity is 30-50 percent |
| 28° | The temperature is 26-29 percent, and the humidity is 30-60 percent |
| 26° | The temperature is 25-28.5 percent, and the humidity is 30-60 percent |

TABLE 1
Here, the current target temperature and humidity range corresponding to the current preset temperature of the air conditioner may be determined according to the correspondence between the stored preset temperature and the target temperature and humidity range. As shown in table 1, if the current preset temperature is 26 °, the obtained current target temperature and humidity range is 25-28.5 ° and the humidity is 30% -60%.
After the current target temperature and humidity range corresponding to the current preset temperature of the air conditioner is determined, the air conditioner can be controlled, and the temperature and the humidity of an air conditioning action area are adjusted to be matched with the current target temperature and humidity range.
Fig. 1 is a flowchart illustrating air conditioning control methods according to an exemplary embodiment of , where, as shown in fig. 1, the air conditioning control process includes:
step 101: the method comprises the steps of obtaining a current temperature value in a current temperature and humidity value of an air conditioner action area, a temperature value of an inner machine coil pipe of the air conditioner and an operation frequency value of a compressor, and determining the current humidity value in the current temperature and humidity value.
In the embodiment of the invention, the air conditioner can adjust the temperature and the humidity of the air conditioning action area, the current temperature and humidity values comprise a current temperature value and a current humidity value, is the current temperature value and the current humidity value of the air conditioning action area can be obtained through a corresponding temperature sensor in the air conditioning system, and the current humidity value in the current temperature and humidity value can be obtained in various modes.
Therefore, not only the current temperature value in the current temperature and humidity value of the air conditioning action area, but also the internal machine coil temperature value and the compressor operation frequency value of the air conditioner are required to be obtained, and then the current humidity value in the current temperature and humidity value is determined according to the obtained value, which can include: obtaining a current humidity value in the current temperature and humidity values through a formula (1) according to the temperature value of an inner machine coil of the air conditioner and the running frequency value of a compressor; or, obtaining the opening value of an expansion valve in the air conditioner, and obtaining the current humidity value in the current temperature and humidity value through a formula (2) according to the temperature value of the coil pipe of the internal machine, the running frequency value of the compressor and the opening value.

Rh＝A2*T1+B2*T2+C2Hz + Df + F-formula (2)
Wherein Rh is the current humidity value, T1 is the current temperature value, T2 is the temperature value of the coil of the internal machine, hz is the running frequency value of the compressor, f is the opening value, A1、B1、C1、A2、B2、C2D, E, F are constants determined according to the type of air conditioner.
For example, for type air conditioners, a is preferably counted through multiple debugs1A constant of 8 or more and 12 or less, B1Is a constant of-12 or more and-8 or less, C1Is a constant between-2 and-1, and E is a constant between-10 and 20, so that the current humidity value can be obtained from the formula (1).
When T1 is 25, T2 is 14, hz is 50, its corresponding a1＝10，B1＝-10，C1The correction value E is 10, and the current humidity value Rh is 70% by formula (1).
Of course, for other types of air conditioners, a can be determined through multiple debugging statistics1、B1、C1Preferred value range of E, or determining A2、B2、C2Preferred values for D, F are not specifically illustrated at .
Therefore, a humidity sensor is not required to be added, the current humidity value can be obtained only according to the temperature value of the coil pipe of the internal machine of the air conditioner, the running frequency value of the compressor and the like, the hardware requirement is reduced, the space of the air conditioner is saved, and the resource is further saved in steps.
Step 102: is it determined whether the current temperature value of the current temperature-humidity value is within the temperature range of the current target temperature-humidity range? If yes, go to step 104, otherwise go to step 103.
The current temperature and humidity value comprises a current temperature value and a current humidity value, and the corresponding current target temperature and humidity range also comprises: a humidity range and a humidity range. When the current temperature and humidity value is not matched with the current target temperature and humidity range, the operation mode of the air conditioner can be adjusted. In the implementation of the invention, the temperature can be compared, the current temperature value is adjusted to the temperature range of the current target temperature and humidity range, and then the operation mode of the air conditioner is adjusted according to the current humidity value, thereby realizing the temperature control and the humidity control. Therefore, if the current temperature value in the current temperature and humidity value is not within the temperature range of the current target temperature and humidity range, step 103 is executed; if the current temperature value is within the temperature range, step 104 is executed.
Step 103: and adjusting the operation mode of the air conditioner according to the current temperature value until the current temperature value is in the temperature range.
And adjusting the operation mode of the air conditioner according to the current temperature value until the current temperature value is in the temperature range.
The method specifically comprises the steps of adjusting the air conditioner to a dehumidification mode to operate when the current temperature value is larger than an upper temperature limit value of a temperature range, wherein the dehumidification mode comprises a refrigeration operation mode and an th frequency operation mode of the compressor, the th frequency is larger than a set frequency, or the dehumidification mode comprises the refrigeration operation mode, the th frequency operation mode of the compressor and a flow rate of an expansion valve smaller than a set flow rate, and adjusting the air conditioner to a th heating mode to operate when the current temperature value is smaller than a lower temperature limit value of the temperature range, wherein the th heating mode comprises a heating operation mode and a th frequency operation mode of the compressor, or an electric heating mode.
Under the air conditioner refrigeration mode of operation, the compressor high frequency operation, that is, the compressor frequency operation mode , frequency is greater than the frequency of setting for, and at this moment, the indoor set coil temperature of air conditioner will be lower, and generally will be lower than air dew point temperature, like this, the temperature of the regional effect of relatively fast reduction air conditioner.
Therefore, the acquired current temperature value can be compared with the upper temperature limit value of the temperature range in the current target temperature and humidity range, if the current temperature value is greater than the upper temperature limit value of the temperature range, the air conditioner is adjusted to a dehumidification mode to operate, at the moment, the air conditioner is in a refrigeration working mode, the compressor is in an th frequency operation mode, the flow of an expansion valve in the air conditioning system can be reduced, and therefore the cooling speed is accelerated .
In the air-conditioning heating operation mode, if the compressor operates in the th frequency operation mode, the temperature of the air-conditioning operation area can be rapidly increased, and the mode can be determined as the th temperature increasing mode.
Therefore, the acquired current temperature value can be compared with the lower temperature limit value of the temperature range in the current target temperature and humidity range, if the current temperature value is smaller than the lower temperature limit value of the temperature range, the air conditioner is adjusted to th heating mode to operate, at the moment, the air conditioner is in a heating working mode, and the compressor is in the th frequency operation mode, so that the heating speed is increased by .
At present, many air conditioners may have an electric heating function, and the temperature of the air conditioning active area may be raised by heat generated by heating through the heating wire, so that the th heating mode may include not only a heating operation mode and a th frequency operation mode of the compressor, but also an electric heating mode, so that if the current temperature value is less than the lower limit value of the temperature range, the air conditioner may be adjusted to the electric heating mode to operate in the th heating mode, and the temperature of the air conditioning active area may be raised as fast as possible.
Step 104: and adjusting the operation mode of the air conditioner according to the current humidity value in the current temperature and humidity values.
Because the current temperature is in the temperature range of the current target temperature and humidity range, the operation mode of the air conditioner can be adjusted according to the current humidity value in the current temperature and humidity value.
If the current humidity value is larger than the upper limit value of the humidity in the humidity range in the current target temperature and humidity range, the air conditioner is adjusted to a dehumidification mode to operate, wherein the dehumidification mode comprises a refrigeration operation mode and an th frequency operation mode of the compressor, the th frequency is larger than a set frequency, or the dehumidification mode comprises a refrigeration operation mode, a th frequency operation mode of the compressor and a flow rate of an expansion valve smaller than a set flow rate, and if the current humidity value is smaller than the lower limit value of the humidity in the humidity range in the current target temperature and humidity range, the air conditioner is adjusted to a second heating mode to operate, wherein the second heating mode comprises a heating operation mode and a second frequency operation mode of the compressor, and the second frequency is smaller than the set frequency or an electric heating mode.
Under the refrigeration working mode of the air conditioner, the compressor runs at high frequency, namely the th frequency running mode of the compressor, at the moment, the temperature of an inner machine coil of the air conditioner is lower, is lower than the dew point temperature of air generally, therefore, water vapor in the air can be condensed, and the humidity of an air conditioning action area can be reduced.
Therefore, if the current humidity value is greater than the limit value on the humidity, the air conditioner can be adjusted to the dehumidification mode to operate, at the moment, the air conditioner is in the refrigeration mode, the compressor operates at high frequency, the temperature of an inner machine coil pipe of the air conditioner is lower than the dew point temperature of the air, therefore, the water vapor in the air can be condensed, and the humidity of an air conditioning action area can be reduced. When the air conditioning control process is completed, the process may return to step 101 to start the next air conditioning control process.
In the air-conditioning heating working mode, if the compressor is in the second frequency running mode, the second frequency is lower, is smaller than the set frequency, and the temperature of an indoor unit coil of the air conditioner is higher than the dew point temperature of air, so that water vapor in the air cannot be condensed, and at the moment, the humidity of an air-conditioning acting area can be adjusted.
Therefore, when the current humidity value is smaller than the lower humidity limit value, the air conditioner can be operated in the second heating mode, namely the air conditioner is in the heating operation mode, and the compressor is operated in the second frequency operation mode, so that the humidity of the action area of the air conditioner can be adjusted.
