Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
A high-temperature sterilization method for an air conditioner according to an embodiment of the present application is described below with reference to fig. 1 to 3.
As shown in fig. 1, a high-temperature sterilization method for an air conditioner according to the present application includes:
s1: acquiring a temperature value of the indoor heat exchanger;
s2: when the temperature value of the indoor heat exchanger is not equal to the preset indoor heat exchanger threshold value, adjusting the rotating speed of the indoor fan and/or the frequency of the outdoor compressor;
s3: acquiring the outdoor exhaust temperature of a refrigerant at an exhaust port of an outdoor compressor;
s4: and selectively adjusting the frequency of the outdoor compressor according to the outdoor exhaust temperature and a preset exhaust frequency limiting temperature threshold value.
According to the high-temperature sterilization method, an indoor heat exchanger threshold value is preset, and if the temperature value of the indoor heat exchanger is not equal to the indoor heat exchanger threshold value, the rotating speed of an indoor fan and/or the frequency of an outdoor compressor are/is adjusted. For example, the rotation speed of the indoor fan or the frequency of the outdoor compressor may be adjusted individually, or the rotation speed of the indoor fan and the frequency of the outdoor compressor may be adjusted simultaneously.
Since the temperature value of the indoor heat exchanger is affected by the frequency of the outdoor compressor, how to adjust the frequency of the compressor has a small effect on the temperature value of the indoor heat exchanger. The frequency of the outdoor compressor is selectively adjusted by acquiring the outdoor exhaust temperature of the refrigerant at the exhaust port of the outdoor compressor and comparing the outdoor exhaust temperature with the preset exhaust frequency limiting temperature threshold value.
It should be noted that the adjustment of the frequency of the compressor is premised on the temperature of the indoor heat exchanger meeting the requirement, and the rotation speed adjustment of the indoor fan and the frequency adjustment of the outdoor compressor are to achieve the best sterilization effect of the indoor heat exchanger.
According to the high-temperature sterilization method for the air conditioner, the temperature value of the indoor heat exchanger is kept in the optimal sterilization temperature range by adjusting the rotating speed of the indoor fan and the frequency of the outdoor compressor; meanwhile, the frequency of the outdoor compressor can be controlled by the relation between the outdoor exhaust temperature and the exhaust frequency limiting temperature threshold value, so that the frequency of the outdoor compressor is always kept in a proper range, and the outdoor exhaust temperature is not too high.
According to some embodiments of the present application, the S2 includes:
s21: when the temperature value of the indoor heat exchanger does not reach the preset threshold value of the indoor heat exchanger, reducing the rotating speed of an indoor fan and increasing the frequency of an outdoor compressor;
s22: and when the temperature value of the indoor heat exchanger exceeds a preset indoor heat exchanger threshold value, increasing the rotating speed of the indoor fan and reducing the frequency of the outdoor compressor.
When the temperature value of the indoor heat exchanger does not reach the preset threshold value of the indoor heat exchanger, the temperature value of the indoor heat exchanger does not reach the optimal sterilization and disinfection effect, and therefore the temperature value of the indoor heat exchanger can be improved by reducing the rotating speed of an indoor fan and increasing the frequency of an outdoor compressor. Specifically, as the rotating speed of the indoor fan is reduced, the heat exchange efficiency between the indoor heat exchanger and the indoor air is reduced, so that the temperature of the indoor heat exchanger is increased; as the frequency of the compressor is increased, the high-temperature refrigerant can more quickly reach the indoor heat exchanger, so that the temperature of the indoor heat exchanger is directly increased.
When the temperature value of the indoor heat exchanger exceeds a preset indoor heat exchanger threshold value, the temperature value of the indoor heat exchanger is over-high. Therefore, it is required to reduce the temperature value of the indoor heat exchanger. The heat exchange speed of the indoor heat exchanger and air is increased by increasing the rotating speed of the fan, and the speed of the high-temperature refrigerant reaching the indoor heat exchanger is reduced by reducing the frequency of the compressor, so that the temperature value of the indoor heat exchanger is rapidly reduced.
In some embodiments of the present application, the exhaust gas frequency limiting temperature threshold comprises a first exhaust gas frequency limiting temperature threshold, and step S4 comprises:
s41: when the outdoor exhaust temperature does not reach the first exhaust frequency limiting temperature threshold value, reducing the rotating speed of the indoor fan and/or increasing the frequency of the outdoor compressor;
s42: when the outdoor exhaust temperature reaches the first exhaust frequency limiting temperature threshold, the frequency of the outdoor compressor is not regulated to rise;
s43: when the outdoor discharge temperature falls below the first discharge frequency limiting temperature threshold, the indoor fan speed is reduced and/or the frequency of the outdoor compressor is increased.
Since the refrigerant discharged from the discharge port of the compressor reaches the indoor heat exchanger, the outdoor discharge temperature directly affects the temperature value of the indoor heat exchanger.
When the outdoor exhaust temperature does not reach the first exhaust frequency limiting temperature threshold value, the temperature value of the indoor heat exchanger cannot reach the optimal sterilization and disinfection effect, so that the temperature value of the indoor heat exchanger can be increased by reducing the rotating speed of the indoor fan or/and increasing the frequency of the outdoor compressor, and the outdoor exhaust temperature can be increased by increasing the temperature value of the indoor heat exchanger in turn, so that the frequency of the outdoor compressor is influenced.
When the outdoor exhaust temperature reaches the first exhaust frequency limiting temperature threshold, the frequency rise of the outdoor compressor is not regulated any more. That is, the frequency of the outdoor compressor may be maintained so that the temperature value of the indoor heat exchanger is maintained at a suitable temperature.
When the outdoor exhaust temperature is reduced to be lower than the first exhaust frequency limiting temperature threshold value, the adjustment range of the rotating speed of the indoor fan or/and the frequency of the outdoor compressor is over large, the rotating speed of the indoor fan can be reduced and/or the frequency of the outdoor compressor can be increased to increase the temperature value of the indoor heat exchanger, and the increase of the temperature value of the indoor heat exchanger can increase the outdoor exhaust temperature in turn, so that the frequency of the outdoor compressor is influenced.
According to some embodiments of the application, the exhaust gas frequency limiting temperature threshold comprises: a second exhaust gas frequency limiting temperature threshold, and the step S4 includes:
s44: controlling the frequency of the outdoor compressor to decrease when the outdoor exhaust temperature reaches or exceeds a second exhaust frequency limiting temperature threshold;
s45: and when the outdoor exhaust temperature is less than the second exhaust frequency limiting temperature threshold and is greater than or equal to the first exhaust frequency limiting temperature threshold, maintaining the current frequency of the outdoor compressor.
It should be noted that, in the present application, the second exhaust limiting temperature threshold is greater than the first exhaust limiting temperature threshold, and in the above steps S41, S42 and S43, there may be hysteresis in the change of the outdoor exhaust temperature, so that the outdoor exhaust temperature may be greater than the first exhaust limiting temperature threshold.
When the outdoor exhaust temperature reaches or exceeds the second exhaust frequency limiting temperature threshold, the temperature value of the indoor heat exchanger possibly exceeds the optimal sterilization temperature value, so that the frequency of the outdoor compressor can be directly adjusted, the amount of refrigerant reaching the indoor heat exchanger in unit time is reduced, and the temperature value of the indoor heat exchanger is further reduced.
And when the outdoor exhaust temperature is less than the second exhaust frequency limiting temperature threshold and is greater than or equal to the first exhaust frequency limiting temperature threshold, maintaining the current frequency of the outdoor compressor. That is, when the outdoor exhaust temperature is at the first exhaust frequency-limiting temperature threshold and the second exhaust frequency-limiting temperature threshold, it is indicated that the temperature value of the indoor heat exchanger is appropriate and is within a temperature range of better sterilization and disinfection, so that the current frequency of the outdoor compressor can be maintained.
The exhaust limiting temperature threshold comprises: a third exhaust gas frequency limiting temperature threshold, and the step S4 includes: s46: and when the outdoor exhaust temperature exceeds a third exhaust frequency limiting temperature threshold value, stopping the operation of the compressor.
The third exhaust gas frequency limiting temperature threshold is greater than the second exhaust gas frequency limiting temperature threshold. That is, when the outdoor exhaust temperature is greater than the third exhaust frequency limiting temperature threshold, it indicates that the temperature value of the indoor heat exchanger is very high, which may have a negative effect on the service life of the indoor heat exchanger, in order to prevent this. The compressor is directly stopped, so that the temperature value of the indoor heat exchanger is rapidly reduced.
