Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
According to the air conditioning unit control method, natural environment information such as altitude information and weather information (such as solar radiation information, rainfall information and wind speed information) of the air conditioner and operation load (such as condensing pressure (or called high pressure), evaporating pressure (or called low pressure) and pressure ratio) of the air conditioning unit are detected, the altitude information, the weather information and the operation load are comprehensively considered, and the air conditioning unit (such as a fan, a compressor and an electronic expansion valve) is controlled. Various control schemes are described in detail below.
Fig. 1 is a flowchart illustrating a method for controlling an air conditioner based on altitude information according to some embodiments of the present disclosure.
As shown in fig. 1, the method of this embodiment includes:
in step 110, altitude information of the air conditioner is acquired.
The altitude information can be detected by a Global Positioning System (GPS). The GPS can be installed in an outdoor unit of an air conditioner, for example.
In step 120, the fan frequency of the air conditioner is adjusted according to the altitude information of the air conditioner and the condensing pressure information of the air conditioner.
Wherein, the condensing pressure or high pressure represents the compressor discharge pressure. The condensing pressure information can be represented by a pressure value and can also be represented by a gaseous saturation temperature of the corresponding refrigerant at the current pressure.
In some embodiments, adjusting the fan frequency of the air conditioner includes:
in step 121, the fan change frequency is determined according to the difference information between the current condensing pressure information of the air conditioner and the preset condensing pressure information.
For example, the fan change frequency is equal to (current condensing pressure information of the air conditioner — preset condensing pressure information) × change frequency corresponding to unit condensing pressure information, where the change frequency corresponding to the unit condensing pressure information is, for example, 3 Hz.
In step 122, a first fan frequency is determined according to the current fan frequency and the fan variation frequency.
For example, the first fan frequency is the current fan frequency + the fan change frequency.
And then, steps 123 and 124 are executed, so that the fan frequency can be adjusted according to the altitude information of the air conditioner, the current condensing pressure information of the air conditioner and the first fan frequency.
In step 123, a first weighting factor is determined according to the altitude information of the air conditioner and the current condensing pressure information of the air conditioner.
In some embodiments, the value of the first weighting factor increases as the altitude at which the air conditioner is located increases, and increases as the current condensing pressure of the air conditioner increases.
Optionally, when the altitude of the air conditioner is greater than the preset height, the value of the first weighting coefficient increases with the increase of the altitude of the air conditioner, and increases with the increase of the current condensing pressure of the air conditioner; when the altitude of the air conditioner is not greater than the preset altitude, the value of the first weighting coefficient may remain unchanged. For example, the value of the first weighting factor remains 1, which is equivalent to not performing a weighting calculation on the first fan frequency.
In step 124, the first fan frequency is weighted by the first weighting factor, and the result is used as the adjusted fan frequency.
An application example is listed below. It should be noted that the numerical values in the application examples are only exemplary and are not used to limit the present disclosure.
A high altitude validation flag is set, which is 1 (indicating validation) when the altitude is greater than, for example, 1000m, and 0 (indicating non-validation) otherwise.
The following calculations were performed:
the fan change frequency is (current condensing pressure information of the air conditioner-preset condensing pressure information) x 3Hz,
the first fan frequency is equal to the current fan frequency plus the fan change frequency.
When the high altitude validation flag is 0, in the cooling mode, the actual frequency of the fan (i.e., the outer fan) is controlled according to the first fan frequency.
When the high altitude validation flag is 1, in the cooling mode, the actual frequency of the fan (i.e., the outer fan) is controlled according to the frequency obtained by performing weighted calculation on the first fan frequency in table 1:

In some embodiments, the value of the second weighting coefficient corresponding to the solar radiation information increases with the intensity of the solar radiation and increases with the current condensing pressure of the air conditioner.
Optionally, when the solar radiation information is greater than the preset radiation value, a value of a second weighting coefficient corresponding to the solar radiation information increases with the increase of the solar radiation intensity, and increases with the increase of the current condensing pressure of the air conditioner; when the solar radiation information is not greater than the preset radiation value, the value of the second weighting coefficient corresponding to the solar radiation information may be kept unchanged, for example, kept at 1, which is equivalent to not performing weighting calculation on the first fan frequency.
In step 224, a weighted calculation is performed on the first fan frequency by using a second weighting coefficient corresponding to the solar radiation information, and the calculation result is used as the adjusted fan frequency.
An application example is listed below.

Optionally, when the rainfall information is greater than the preset rainfall, the value of the second weighting coefficient corresponding to the rainfall information decreases with the increase of the rainfall, and increases with the increase of the current condensing pressure of the air conditioner; when the rainfall information is not greater than the preset rainfall, the value of the second weighting coefficient corresponding to the rainfall information may be kept unchanged, for example, kept to 1, which is equivalent to not performing weighting calculation on the first fan frequency.

Those skilled in the art will appreciate that parameters may be validatedVarious modifications of the above formula are obtained, but it is obvious that the above formula and its various modifications are within the scope of the present disclosure. Various variations of the above formula include, for example, but are not limited to, F2＝P1×Pa×F1，F2＝P1×Pb×F1，F2＝P1×Pc×F1，F2＝P1×Pa×Pb×F1，F2＝P1×Pa×Pc×F1，F2＝P1×Pa×Pc×F1，F2＝Pa×Pb×F1，F2＝Pa×Pc×F1。

According to the air conditioning unit control method and device, the air conditioning unit (such as the fan frequency) is adjusted according to the operation condition (such as the fan operation frequency and the condensation pressure) of the air conditioning unit, and the air output requirement under a specific service scene can be met. In the process, the operation load (such as evaporation pressure, pressure ratio, condensation pressure and the like) of the air conditioner is detected at the same time, and the air conditioning unit (such as a compressor and an electronic expansion valve) is adjusted, so that the air output is ensured to achieve the refrigeration effect as soon as possible, and the air conditioning load is in a reasonable range.
For example, in the case of air-conditioning refrigeration, when the evaporation pressure information of the air conditioner is less than the first preset pressure information, i.e., "low pressure" is too low, the frequency of the compressor is reduced, and the opening of the electronic expansion valve is increased. When the evaporation pressure information of the air conditioner is larger than the second preset pressure information, namely the low pressure is too high, the frequency of the compressor is improved, and the opening of the electronic expansion valve is reduced.
Therefore, the air output of the air conditioning unit is ensured, and meanwhile, the air conditioning loads such as the condensing pressure, the evaporating pressure and the like are in a reasonable range.
