The effect of air conditioning.

There are mainly two existing air conditioning condensation control schemes. One is to use heat-insulating pads or hollow structure designs to reduce heat conduction, but this method cannot solve the effect of turbulent flow at the air outlet (during the flow of fluid, the faster the tassel The lower the pressure), the cooled air is blown out from the air outlet, which will "attract" the air on both sides to mix and flow in, forming turbulent flow on both sides of the air outlet, and the heat exchange will still cause condensation. The other is to limit the operation of the compressor at a lower fixed frequency under the condition of the speed of the indoor fan during the cooling mode or dehumidification mode of the air conditioner. However, in the case of the same temperature and different humidity, this method is likely to cause poor anti-condensation effect at high humidity at a fixed temperature, and affect the cooling of the air conditioner at low humidity, and in the case of high wind and unlimited frequency settings, this The method cannot completely avoid the occurrence of the phenomenon.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The present invention provides an air conditioner anti-condensation control method, as shown in Figure 1, the air-conditioner anti-condensation control method includes the following steps:

Step S101: Obtain the temperature of key condensation parts and the dew point temperature in the current environment.

Step S102: Comparing the temperature of the key condensation part with the dew point temperature.

Step S103: If it is judged that the temperature at the key condensation point is less than or equal to the dew point temperature, reduce the target frequency, and adjust the frequency reduction rate of the target frequency according to the difference between the temperature at the key condensation point and the dew point temperature.

When the air conditioner is running, the temperature T _x of the key condensation point and the dew point temperature T _d in the current environment are obtained. Compare the temperature of the key condensation parts with the dew point temperature, and calculate the temperature difference between the temperature of the key condensation parts and the dew point temperature, △T=T _x -T _d .

If it is judged that the temperature T _x of the key condensation part is greater than the dew point temperature T _d , that is, △T=T _x -T _d > 0°C, it is determined that the key condensation part has no risk of condensation, and it will operate according to the preset target frequency f ₀ .

If it is judged that the temperature T _x of the key condensation point is less than or equal to the dew point temperature T _d , that is, △T=T _x -T _d ≤ 0°C, then reduce the target frequency f ₀ to f ₁ , and based on the learned temperature T _x of the key condensation point The difference from the dew point temperature _Td adjusts the frequency-down rate of the target frequency _f0 .

Determine the temperature difference range of the difference between the temperature _Tx of the key condensation part and the dew point temperature _Td , and adjust the frequency reduction rate of the target frequency according to the temperature difference range of the difference ΔT.

When the temperature difference is within the first preset temperature difference range, the frequency reduction rate of the target frequency is adjusted to the first frequency reduction rate. And when the temperature difference is within the second preset temperature difference range, the frequency reduction rate of the target frequency is adjusted to the second frequency reduction rate. The absolute value of the temperature difference corresponding to the first preset temperature difference range is less than or equal to the absolute value of the temperature difference corresponding to the second temperature difference range, and the first frequency reduction rate is smaller than the second frequency reduction rate.

For example, when -5°C<T _x -T _d ≤0°C, the target frequencies f ₀ to f ₁ are adjusted at a frequency reduction rate of 2 Hz every 5 seconds. When T _x -T _d ≤ -5°C, adjust the target frequencies f ₀ to f ₁ at a rate of 2 Hz every 1 second.

Thus, when the temperature difference between the temperature T _x of the key condensation point and the dew point temperature T _d is large, the target frequency can be quickly reduced. When the temperature difference between the temperature Tx of the key condensation part and the dew point temperature _Td is small, it can be adjusted slowly according to the temperature difference, so as to achieve a cooling effect that does not cause condensation and ensures _the best cooling effect.

It should be noted that the range of temperature difference can be further increased according to needs, and different frequency reduction rates can be set to ensure the best cooling effect under different temperature adjustments.

The air conditioning anti-condensation control method provided by the embodiment of the present invention obtains the temperature of the key condensation part and the dew point temperature in the current environment, and compares the temperature of the key condensation part with the dew point temperature. When it is equal to the dew point temperature, reduce the target frequency, and adjust the frequency reduction rate of the target frequency according to the difference between the temperature of the key condensation part and the dew point temperature, so that when the condensation of the air conditioner and the cooling effect are constrained, the situation of no condensation can be guaranteed to ensure the best cooling effect.

As shown in Figure 2, the steps to obtain the temperature of key condensation parts and the dew point temperature in the current environment include:

Step S1011: Acquiring the temperatures of multiple condensation-prone parts of the air conditioner, comparing the temperatures of the condensation-prone parts; determining the lowest temperature among the temperatures of the condensation-prone parts as the temperature of the key condensation parts.

Step S1012: Obtain the ambient temperature, ambient air pressure and relative humidity, and obtain the dew point temperature in the current environment according to the dew point temperature table.

First obtain the temperature of the condensation-prone parts of the air conditioner, such as the temperature of the chilled water, the temperature of the air supply, the temperature of the condensate pipe, etc., and obtain the temperatures of these parts, T ₁ , T ₂ ... T _n .

By simulating and comparing the temperatures of the condensation-prone parts, the lowest temperature among the temperatures of the condensation-prone parts is determined as the temperature of the key condensation parts, that is, the temperature of the key condensation parts T _x = min(T ₀ , T ₁ , T ₃ ...T _n ).

After obtaining the temperature _Tx of the key condensation part, start to obtain the dew point temperature, first obtain the ambient temperature, ambient air pressure and relative humidity, and obtain the dew point temperature in the current environment according to the dew point temperature table.

In order to ensure the best cooling effect in the case of no condensation, after a frequency adjustment, the temperature of the key condensation parts and the dew point temperature in the current environment can be obtained again. Compare the retrieved key condensation site temperature with the dew point temperature. If it is judged that the reacquired key condensation temperature is less than or equal to the reacquired dew point temperature, then reduce the target frequency again, and adjust the frequency reduction of the target frequency according to the difference between the reacquired key condensation temperature and the reacquired dew point temperature rate. If it is judged that the reacquired key condensation site temperature is greater than the reacquired dew point temperature, the target frequency is restored.

Among them, in the process of restoring the target frequency, the current operating frequency is obtained, and the operating frequency is compared with the target frequency. If the operating frequency is lower than the target frequency, the current operating frequency is adjusted to the target frequency at a preset frequency increase rate, for example, every 5 seconds Increase the frequency increase rate by 1Hz to adjust the operating frequency to the target frequency.

Furthermore, the temperature of key condensation points and the dew point temperature in the current environment can also be periodically obtained. For example, the temperature of key condensation parts and the dew point temperature in the current environment are obtained every 5 seconds, and subsequent comparisons and adjustments are made. In this way, the accuracy of frequency modulation can be guaranteed, and the best cooling effect can be achieved without condensation.

Specifically, as shown in FIG. 3 , when the air conditioner is running, the temperature T _x of the key condensation point and the dew point temperature T _d under the current environment are acquired. Compare the temperature of the key condensation parts with the dew point temperature, and calculate the temperature difference between the temperature of the key condensation parts and the dew point temperature, △T=T _x -T _d . If it is judged that the temperature T _x of the key condensation part is greater than the dew point temperature T _d , that is, △T=T _x -T _d > 0°C, it is judged that the key condensation part has no condensation risk, and it operates according to the preset target frequency f ₀ . If it is judged that the temperature T _x of the key condensation point is less than or equal to the dew point temperature T _d , that is, △T=T _x -T _d ≤ 0°C, then reduce the target frequency f ₀ to f ₁ , and based on the known temperature T _x of the key condensation point and The difference in dew point temperature T _d adjusts the frequency reduction rate of the target frequency f ₀ .

After a period of down-frequency operation, the temperature T _x of the key condensation point and the dew point temperature T _d under the current environment are reacquired at intervals of one cycle. Comparing the re-obtained temperature of key condensation parts with the re-acquired dew point temperature, and recalculating the temperature difference between the temperature of key condensation parts and the dew point temperature, △T=T _x -T _d . Similarly, if it is judged that the reacquired temperature T _x of key condensation points is greater than the newly obtained dew point temperature T _d , that is, △T=T _x -T _d >0°C, it is determined that there is no risk of condensation at the key condensation parts, and the target is restored. Frequency, run according to the preset target frequency f ₀ . If it is judged that the temperature T _x of the key condensation point is less than or equal to the dew point temperature T _d , that is, △T=T _x -T _d ≤ 0°C, then reduce the target frequency f ₀ to f ₁ , and based on the known temperature T _x of the key condensation point and The difference in dew point temperature T _d adjusts the frequency reduction rate of the target frequency f ₀ .

The present invention also provides an air conditioner anti-condensation control system. As shown in FIG.

Wherein, the first obtaining module 401 is used to obtain the temperature of the key condensation site. The second obtaining module 402 is used to obtain the dew point temperature in the current environment. The judging module 403 is used to compare the obtained temperature of the key condensation point with the dew point temperature. The processing module 404 is used to reduce the target frequency when the judging module 403 judges that the temperature of the key condensation point is less than or equal to the dew point temperature, and adjust the frequency reduction rate of the target frequency according to the difference between the temperature of the key condensation point and the dew point temperature.

When the air conditioner is running, the first acquisition module 401 acquires the temperature T _x of the key condensation site. The second obtaining module 402 obtains the dew point temperature T _d under the current environment. The judging module 403 compares the temperature of the key condensation point with the dew point temperature, and calculates the temperature difference between the temperature of the key condensation point and the dew point temperature, ΔT=T _x −T _d .

If the judging module 403 judges that the temperature T _x of the key condensation part is greater than the dew point temperature T _d , that is, ΔT=T _x -T _d >0°C, then the judging module 403 judges that there is no risk of condensation at the key condensation part, and the processing module 404 The air conditioner is controlled to operate according to the preset target frequency f ₀ .

If the judging module 403 judges that the temperature T _x of the key condensation point is less than or equal to the dew point temperature T _d , that is, △T=T _x -T _d ≤ 0°C, then the processing module 404 reduces the target frequency f ₀ to f ₁ , and according to the learned key The difference between the temperature T _x of the condensation part and the temperature T _d of the dew point adjusts the frequency reduction rate of the target frequency f ₀ .

The processing module 404 judges the temperature difference range of the difference between the temperature _Tx of the key condensation part and the dew point temperature _Td , and adjusts the frequency reduction rate of the target frequency according to the temperature difference range of the difference ΔT.

The processing module 404 adjusts the frequency reduction rate of the target frequency to a first frequency reduction rate when the temperature difference is within the first preset temperature difference range. When the temperature difference is within the second preset temperature difference range, the processing module 404 adjusts the frequency reduction rate of the target frequency to the second frequency reduction rate. The absolute value of the temperature difference corresponding to the first preset temperature difference range is less than or equal to the absolute value of the temperature difference corresponding to the second temperature difference range, and the first frequency reduction rate is smaller than the second frequency reduction rate.

For example, when -5°C<T _x −T _d ≤0°C, the processing module 404 adjusts the target frequencies f ₀ to f ₁ at a frequency reduction rate of 2 Hz every 5 seconds. When T _x −T _d ≤ -5° C., the processing module 404 adjusts the target frequencies f ₀ to f ₁ at a frequency reduction rate of 2 Hz every 1 second.

Therefore, when the temperature T _x of the key condensation point and the dew point temperature T _d have a large temperature difference, the processing module 404 can quickly reduce the target frequency. When the temperature difference between the temperature _Tx of the key condensation point and the dew point temperature _Td is small, the processing module 404 can slowly adjust according to the temperature difference, so as to achieve a cooling effect that does not cause condensation and ensures the best cooling effect.

The air conditioner anti-condensation control system provided by the embodiment of the present invention obtains the temperature of the key condensation part and the dew point temperature in the current environment, and compares the temperature of the key condensation part with the dew point temperature. When it is equal to the dew point temperature, reduce the target frequency, and adjust the frequency reduction rate of the target frequency according to the difference between the temperature of the key condensation part and the dew point temperature, so that when the condensation of the air conditioner and the cooling effect are constrained, the situation of no condensation can be guaranteed to ensure the best cooling effect.
