Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
An anti-condensation control method of an inverter air conditioner according to an embodiment of the present invention will be described with reference to fig. 1 to 2.
The anti-condensation control method of the inverter air conditioner according to the embodiment of the first aspect of the invention comprises the following steps:
and S1, cooling and starting.
S2, judging whether the compressor continuously operates for a first time; and if not, entering a normal refrigeration control mode.
S3, if yes, judging whether the indoor environment temperature T1 and the outdoor environment temperature T4 meet the conditions that the indoor environment temperature T1 is more than or equal to 24 ℃ and less than or equal to 30 ℃ and the outdoor environment temperature T4 is more than or equal to 24 ℃ and less than or equal to 30 ℃; and if not, entering a normal refrigeration control mode.
S4, if yes, judging whether the rotating speed of the indoor fan is less than k times of the rated rotating speed, wherein k is taken from 50% -60%; that is, the indoor fan is in a middle or low range operation.
And S5, if so, entering an anti-condensation control mode, and under the anti-condensation control mode, comparing the temperature difference range of the dew point temperature and the temperature of the indoor evaporator to adjust the running frequency of the compressor.
The condensation of the indoor unit of the air conditioner means that when the temperature of the parts of the air conditioner is lower than the dew point temperature of the external environment, the ambient hot air generates condensation water on the surface of the parts. The applicant finds that, through intensive research, under the condition that the ambient temperature is 24-30 ℃, the relative humidity in the air is relatively high, particularly in the area in the south of the Yangtze river, condensation is easily generated in the existing air conditioner (including a variable frequency air conditioner), mainly reflected in the phenomena of panel dripping, wall wetting, air outlet dripping and the like, and brings a poor experience effect to user experience.
Therefore, whether the indoor environment temperature and the outdoor environment temperature are within the preset temperature range or not is judged, whether the anti-condensation control mode is entered or not is determined by combining the rotating speed of the fan, and when the anti-condensation control mode is entered, the operating frequency of the compressor is adjusted by comparing the temperature difference range of the dew point temperature and the temperature of the indoor evaporator, so that the temperature of the indoor evaporator is higher than the dew point temperature, and the occurrence of condensation is reduced.
In some embodiments, the anti-condensation control mode includes:
and S51, calculating the relative humidity phi according to the indoor environment temperature T1, wherein phi is 115-2.5T 1.
And finding out the corresponding dew point temperature T according to the indoor environment temperature T1 and the relative humidity phi, and finding out the corresponding dew point temperature T according to the indoor environment temperature T1 and the relative humidity phi. Referring to table 1, the abscissa is the indoor ambient temperature T1, the ordinate is the relative humidity Φ, and each value of T1 and Φ is the corresponding dew point temperature T.
TABLE 1
And calculating a corrected value t 'of the dew point temperature, wherein the t' is t-X, and X is the corrected value of the dew point temperature. X is a fixed value and can be selected empirically, for example, X is 3 ℃, and the controller calculates the corrected value t "of the dew point temperature.
The indoor evaporator temperature T2 is collected, and specifically, the indoor evaporator temperature T2 may be detected by means of a sensor provided on the indoor unit evaporator coil.
And S52, judging the range of the difference value between the T2 and the T 'and correspondingly controlling the frequency of the compressor according to the range of the difference value between the T2 and the T'.
If T2-T is less than or equal to-1, the current frequency of the compressor is kept running.
If T2-T "< -1, the frequency of the current compressor is raised.
If T2-T "> 1, the frequency of the current compressor is reduced.
Thus, the air conditioner is adjusted to an operating state closer to dehumidification by adjusting the frequency of the compressor so that T2 and T ″ are changed correspondingly.
In some embodiments, further comprising: s53, if-1 is not less than T2-T is not less than 1, the comfortable refrigeration control mode is exited after the frequency of the current compressor is kept running for the fourth preset time, and the step S51 is returned. Therefore, when the temperature T2-T is more than or equal to-1 and less than or equal to 1, the air conditioner can perform dehumidification, the current frequency operation of the compressor is kept, the indoor environment temperature T1 and the indoor evaporation temperature T2 are detected again every third preset time, and the range of the difference value of the T2 and the T' is judged again; if the detection result is consistent with the initial result within the fourth preset time, the comfort cooling control mode is exited, and the step S2 is returned to for recalculation.
In some embodiments, further comprising: s54, if T2-T "< -1, increasing the frequency of the current compressor by one gear, and returning to the step S51 every third preset time. It should be noted that "first gear" refers to a frequency increase amount or a frequency decrease amount preset in the system. Thus, when the indoor evaporation temperature is much lower than the dew point temperature, the frequency of the compressor can be increased appropriately so that the difference T2-T' is more in the range of (-1, 1).
In some embodiments, further comprising: and S55, if the current compressor frequency is at the highest set operation frequency, keeping the current frequency to operate for a fourth preset time, and returning to the step S3. Therefore, when the frequency of the compressor is increased to the maximum, no matter what range the difference value of T2-T' is, the compressor runs for the fourth preset time according to the current maximum set frequency, then the compressor exits from the comfort refrigeration control mode, and the compressor returns to the step S2 to acquire the temperature again and recalculate the judgment.
In some embodiments, further comprising: s56, if T2-T "> 1, reducing the frequency of the current compressor by one gear, and returning to the step S51 every third preset time. Thus, when the indoor evaporation temperature is higher than the dew point temperature by a large amount, the frequency of the compressor can be appropriately reduced so that the difference T2-T' gradually approaches the range of (-1, 1).
In some embodiments, further comprising: and S57, if the current compressor frequency is at the lowest set operation frequency, keeping the current frequency to operate for a fourth preset time, and returning to the step S3. Therefore, when the frequency of the compressor is reduced to the lowest, no matter what range the difference value of T2-T' is, the compressor operates for the fourth preset time according to the current highest set frequency, then the comfort cooling control mode exits, and the step S2 is returned to collect the temperature again and calculate and judge again.
In some embodiments, the anti-condensation control mode is exited when any of the following conditions are met:
the first condition is that T1 is more than 30 ℃ or T1 is less than 24 ℃;
the second condition is that T4 is more than 30 ℃ or T4 is less than 24 ℃;
and under the third condition, the rotating speed of the indoor fan reaches k times or more than k times of the rated rotating speed, wherein k can be 0.6.
Therefore, when one of the indoor environment temperature and the outdoor environment temperature is out of the preset temperature range or the rotating speed of the indoor fan is detected to be increased to be higher than the preset rotating speed, the anti-condensation control mode is exited.

As shown in fig. 2, the four-way valve 20 has first to fourth ports, and an inlet and an outlet of the compressor 10 are respectively connected to the first port and the third port of the four-way valve 20; one end of the indoor unit heat exchanger 30 is connected with a second interface of the four-way valve 20; one end of the outdoor heat exchanger 40 is connected to the fourth port of the four-way valve 20; the throttling device 50 is connected between one end of the indoor heat exchanger 30 and the other end of the outdoor heat exchanger 40; the first temperature sensor 60 is connected with the indoor unit heat exchanger 30, and is used for collecting indoor environment temperature T1; the second temperature sensor 70 is connected to the indoor unit heat exchanger 30 to collect the indoor evaporating temperature T2.
