Referring to fig. 1, an embodiment of the present disclosure provides a method for controlling condensation prevention of an air conditioner, including:
s101, obtaining a first temperature change rate of a coil of an air conditioner indoor unit.
In the embodiment, after the air conditioner stably runs in a refrigeration or dehumidification mode, the temperature of a coil pipe of an indoor unit of the air conditioner is detected, and a first temperature change rate is obtained according to the temperature change conditions at adjacent moments; for example, if the air conditioner indoor unit coil T 0 Time of dayTemperature Tp 0 ，T 1 Time temperature Tp 1 Then the first temperature change rate R 1 ＝︱(Tp 0 -Tp 1 )/(T 1 -T 0 )︳。
In the prior art, in order to improve the accuracy of condensation judgment, whether condensation can be generated or not is judged by combining the air volume of a fan of the internal machine or the air pressure difference and other parameters at two sides of a filter screen on the basis of the temperature of the coil pipe of the internal machine; thus, the judgment efficiency is reduced. The condensation production is judged to the rate of temperature change by this embodiment, like this, helps raising the efficiency, and simultaneously, the rate of temperature change can reflect the temperature trend, compares with the temperature value, and its accuracy is higher.
In addition, the temperature of the coil pipe of the internal machine can be obtained by arranging a temperature sensor, and the sensor can be arranged at the coil pipe of the internal machine or at the air outlet; the temperature acquisition frequency can set the acquisition period or be acquired in an irregular time.
S102, determining the operation parameters of the indoor unit fan and controlling the indoor unit fan to operate under the operation parameters under the condition that the first temperature change rate of the coil pipe of the indoor unit of the air conditioner is greater than or equal to a first threshold value and is smaller than a second threshold value.
In this embodiment, the first threshold is a critical value for determining whether an internal unit of the air conditioner generates condensation, that is, when a first temperature change rate of a coil of the internal unit is smaller than the first threshold, the air conditioner does not have a risk of generating condensation, and at this time, the air conditioner keeps a current operation state to operate; when the first temperature change rate of the internal machine coil is larger than or equal to the first threshold value, the air conditioner has the risk of generating condensation, and the air conditioner performs condensation prevention control. Judging the relation between the first temperature change rate of the coil pipe of the indoor unit of the air conditioner and a second threshold value, and controlling the fan of the indoor unit of the air conditioner to operate under the operation parameters if the first temperature change rate of the coil pipe of the indoor unit of the air conditioner is smaller than the second threshold value; the determination of the operation parameters of the internal fan can be to increase the air output of the fan, or to increase the rotating speed of the fan; by increasing the evaporation temperature, the generation of condensation is avoided.
S103, acquiring the running frequency of the compressor under the condition that the first temperature change rate of the coil of the indoor unit of the air conditioner is greater than or equal to a second threshold value; and determining an operation strategy of the compressor or the internal fan according to the operation frequency of the compressor, and controlling the compressor or the internal fan to operate under the operation strategy.
In this embodiment, if the first temperature change rate of the coil of the indoor unit of the air conditioner is greater than or equal to the second threshold, the control strategy for preventing condensation of the air conditioner is determined according to the operating frequency of the compressor, that is, the compressor of the air conditioner or the indoor unit of the air conditioner is determined to operate under the corresponding operating strategy according to the operating frequency of the compressor. For example, when the operating frequency of the compressor is greater than or equal to a preset value, the operation of the fan inner unit is controlled, and the operation strategy can be to increase the rotating speed of the fan or increase the air output; or, when the operation frequency of the compressor is smaller than the preset value, the compressor is controlled to operate, the operation strategy can be to reduce the frequency of the compressor so as to increase the outlet air temperature, or the operation strategy can be to control the return oil of the compressor to increase the frequency so as to eliminate the oil accumulation in the copper pipe and improve the heat exchange coefficient, and the like.
By adopting the method for controlling the air conditioner to prevent condensation, whether the air conditioner has the risk of generating condensation can be judged quickly and accurately, and different control strategies are adopted according to different judgment results, so that the method is beneficial to preventing the air conditioner from generating condensation and improving the use feeling of a user.
Optionally, determining an operation strategy of the compressor or the internal fan according to the frequency of the compressor includes:
under the condition that the operating frequency of the compressor is smaller than the first frequency and larger than the second frequency, oil return of the compressor is controlled, and the operating frequency of the compressor is controlled to be increased to the first frequency; after the compressor operates for the first time, controlling the operating frequency of the compressor to recover to the frequency before the compressor is lifted; and under the condition that the frequency of the compressor is greater than or equal to the first frequency, controlling the rotating speed of the inner fan to increase the set rotating speed.
In the embodiment, if the frequency of the compressor is greater than a preset first frequency, the rotating speed of the inner fan is controlled to be increased to operate; under the condition, the running frequency of the compressor is higher, the flow rate of the refrigerant is improved, the oil return effect of the compressor is better, and the possibility of oil accumulation in the copper pipe is lower; if the compressor is controlled to act, no obvious effect is achieved on improving the heat exchange coefficient; therefore, the evaporation temperature is increased by controlling the lifting rotating speed of the inner fan, and the condensation prevention control is realized.
If the running frequency of the compressor is smaller than the first frequency and larger than the second frequency, oil return of the compressor is controlled, and the running frequency is increased to the first frequency; in this example, under the condition that the operating frequency of the compressor is relatively low, the temperature change rate of the coil pipe of the internal machine is relatively high, and the reason for the situation may be that oil is accumulated inside the copper pipe, the heat exchange coefficient is influenced, and the heat conduction effect is reduced; therefore, the oil accumulation problem of the copper pipe is solved by controlling the oil return of the press and improving the operation frequency, and the heat conduction effect is further improved.
In addition, after the running frequency of the compressor is increased and runs for a first time, the running frequency of the compressor is restored to the running frequency before the operation; so, can avoid the long-time high frequency operation of compressor, cause air conditioner air-out temperature to reduce too fast to produce the risk of condensation.
Optionally, in the case that the operating frequency of the compressor is less than the second frequency, controlling oil return of the compressor, and controlling the operating frequency of the compressor to be increased to the second frequency; after the compressor runs for the second time, controlling the running frequency of the compressor to recover to the frequency before the compressor is lifted; wherein the first length of time is longer than the second length of time.
In this embodiment, at the in-process that control compressor operating frequency promoted, in order to avoid compressor frequency to promote too high, influence compressor performance or cause air conditioner air-out temperature to hang down and produce the condensation, set for the second frequency, when compressor operating frequency is less than the second frequency, promote compressor operating frequency to the second frequency, realize the steady promotion of compressor frequency, make the inside long-pending oil of copper pipe obtain the mediation simultaneously.
Optionally, after the operating frequency of the compressor is controlled to be restored to the frequency before the lifting, a second temperature change rate of a coil pipe of an air conditioner indoor unit is obtained; and under the condition that the second temperature change rate of the coil pipe of the indoor unit of the air conditioner is greater than or equal to a second threshold value, controlling the rotating speed of the fan of the indoor unit to be increased to a set rotating speed.
In this embodiment, after the compressor is controlled to operate under the operation strategy, the temperature change rate of the coil pipe of the indoor unit of the air conditioner, i.e. the second temperature change rate, is obtained again, whether the second temperature change rate is smaller than the preset second threshold value or not is judged, and if the second temperature change rate is still larger than or equal to the preset second threshold value, it is indicated that oil is not accumulated inside the copper pipe.
With reference to fig. 2, another method for controlling condensation prevention of an air conditioner according to an embodiment of the present disclosure includes:
s201, obtaining a first temperature change rate of a coil pipe of an air conditioner internal unit.
Optionally, before obtaining the temperature change rate of the coil pipe of the indoor unit of the air conditioner, the method further includes: acquiring the frequency of a compressor, the rotating speed of an inner fan and the rotating speed of an outer fan; and acquiring the temperature of the coil pipe of the indoor unit of the air conditioner when the frequency of the compressor and the rotating speeds of the indoor unit fan and the outdoor unit fan are in an unchanged state.
Condensation occurs during normal operation of the air conditioner, and usually occurs after the air conditioner stably operates for a period of time, so in the embodiment, the condensation prevention control is to obtain the temperature change rate of a coil pipe of an air conditioner internal unit after the air conditioner stably operates, and judge whether condensation is likely to occur; generally, when the frequency of a compressor and the rotating speed of fans of an internal and external machine of an air conditioner are in a relatively unchanged state, the air conditioner enters a stable operation stage, namely the frequency of the compressor fluctuates and the rotating speed of the fans of the internal and external machine of the air conditioner fluctuates within an allowable fluctuation range, and the air conditioner enters the stable operation stage; after the air conditioner stably operates, condensation prevention control is performed, and resource saving is facilitated.
S202, under the condition that the first temperature change rate of the coil pipe of the indoor unit of the air conditioner is larger than or equal to a first threshold value and smaller than a second threshold value, the rotating speed of the fan of the indoor unit is controlled to be increased for a set rotating speed operation set time length.
In this embodiment, if the first temperature change rate of the coil pipe of the air conditioner internal unit is greater than or equal to the first threshold value and less than the second threshold value, the rotating speed of the internal unit fan is increased, the air quantity is increased by increasing the rotating speed of the internal unit fan, the evaporation temperature is increased, and condensation is avoided. The set time length can be determined according to requirements, for example, the rotating speed of the fan is increased, and the use feeling of a user can be influenced, so that the set time length is generally short; however, in order to better avoid the generation of dew, it is generally desirable to set the time period to be long. In addition, the set rotation speed can be 30rpm, 50rpm, 600rpm and the like for each lifting, and can be set in combination with actual requirements.
S203, acquiring a third temperature change rate of a coil pipe of an air conditioner indoor unit; and if the third temperature change rate of the coil pipe of the indoor unit of the air conditioner is greater than or equal to the first threshold value and less than the second threshold value, controlling the fan of the indoor unit to increase the set rotating speed again.
In this embodiment, after the air conditioner internal unit has been lifted the rotational speed operation and has been set for a long time, can acquire the temperature change rate of air conditioner internal unit coil pipe once more, third temperature change rate promptly, judge whether third temperature change rate satisfies the settlement threshold value, when not satisfying, can promote the internal unit rotational speed once more. As an example, after the rotating speed is increased, the temperature change rate of a coil pipe of an air conditioner indoor unit can be obtained regularly or irregularly, and if the temperature change rate does not meet a threshold value, the rotating speed can be increased continuously until the temperature change rate meets the set threshold value.
Optionally, if the rotation speed of the internal machine fan exceeds the maximum rotation speed of the internal machine fan after the set rotation speed is increased again, the internal machine fan is controlled to operate at the maximum rotation speed.
In this embodiment, the air conditioner internal unit fan may exceed the maximum rotational speed of the air conditioner internal unit after the rotational speed is raised several times, and in this case, considering factors such as air conditioner performance and service life, the air conditioner internal unit can operate at the maximum rotational speed, and the overload operation is not needed.
S204, acquiring the running frequency of the compressor under the condition that the first temperature change rate of the coil pipe of the indoor unit of the air conditioner is greater than or equal to a second threshold value; and determining an operation strategy of the compressor or the internal fan according to the operation frequency of the compressor, and controlling the compressor or the internal fan to operate under the operation strategy.
In this embodiment, through the mode that control compressor and fan internal unit combine, realize the air conditioner and prevent the condensation, avoid producing the condensation and cause the liquid that returns, influence air conditioner stability.

A temperature sensor module 21 configured to obtain a rate of change of a temperature of a coil of an air conditioner internal unit; the first control module 22 is configured to determine an operation parameter of the indoor unit fan and control the indoor unit fan to operate under the operation parameter when the temperature change rate of the coil of the indoor unit of the air conditioner is greater than or equal to a first threshold and smaller than a second threshold; the second control module 23 is configured to obtain the operating frequency of the compressor when the temperature change rate of the coil of the air conditioner indoor unit is greater than or equal to a second threshold value; and determining an operation strategy of the compressor or the internal fan according to the operation frequency of the compressor, and controlling the compressor or the internal fan to operate under the operation strategy.
The device for controlling the air conditioner to prevent condensation is beneficial to quickly and accurately reflecting whether the air conditioner possibly has the problem of condensation according to the temperature change rate of the coil pipe of the indoor unit of the air conditioner, and the condensation is prevented by controlling the mode of combining the oil return frequency of the compressor and the rotating speed of the fan of the indoor unit.
