As shown in connection with fig. 2, the present disclosure provides a method for controlling an air conditioner, comprising:
s201, the processor obtains the temperature regulation rate in the space where each indoor unit is located.
The indoor unit is an indoor unit in a start-up state, and the control valves in the indoor units in the start-up state are all opened to a certain opening degree, and the opening degree at this time is referred to as an initial opening degree.
S202, the processor obtains a target rate range.
And S203, when the temperature regulation rate in the space where the indoor unit is located is not in the target rate range, the processor regulates the opening degree of the regulating valve in the indoor unit so that the temperature regulation rate approaches the target rate range.
By adopting the method for controlling the air conditioner provided by the embodiment of the disclosure, the temperature regulation rate in the space where each indoor unit in the air conditioner is located is obtained, if the temperature regulation rate is not in the target rate range, the refrigerant quantity is excessive or too little, and at the moment, the opening degree of the regulating valve in the indoor unit is regulated, so that the temperature regulation rate approaches to the target rate range. Therefore, the temperature regulation capacity of the indoor unit can be determined according to the actual temperature regulation rate, so that the refrigerant quantity flowing through the indoor unit can be accurately judged, the opening of the regulating valve is regulated based on the refrigerant quantity, and the accuracy of the distribution of the refrigerant in each indoor unit is improved.
Optionally, the determining method of the initial opening degree includes: the processor obtains the air pipe temperature and the liquid pipe temperature of each indoor unit to determine the initial opening of each indoor unit. More specifically, the processor detects the air pipe temperature and the liquid pipe temperature corresponding to each indoor unit, calculates a difference between the air pipe temperature and the liquid pipe temperature, compares the difference with a preset target superheat degree, and sets the initial opening as the first opening if the difference is larger than the target superheat degree. And if the difference is equal to the target superheat degree, setting the initial opening degree as a second opening degree. And if the difference is smaller than the target superheat degree, setting the opening degree as a third opening degree. Wherein the first opening is larger than the second opening, and the second opening is larger than the third opening. In this way, the initial opening degree which is more in line with the actual running situation is set, and the number of subsequent adjustment times or the adjustment amplitude can be reduced over a certain length, so that unnecessary energy and device loss are avoided.
Optionally, the air conditioner further comprises: and the temperature sensor is arranged on the indoor unit and is configured to detect the return air temperature of the indoor unit. At least one temperature sensor is provided corresponding to each indoor unit.
Optionally, the processor obtains a temperature adjustment rate in a space in which each indoor unit is located: the processor obtains the return air temperature of the indoor unit before and after unit time, and determines the temperature regulation rate in the space where the indoor unit is located according to the difference value between the return air temperatures. Therefore, the return air temperature is monitored in real time, and the temperature regulation rate of each indoor unit in the space can be accurately determined, so that the temperature regulation capacity of the indoor units is accurately determined.
Optionally, the method for controlling an air conditioner further includes: the processor obtains the ambient temperature in the space in which the indoor unit is located. And under the condition that the ambient temperature reaches the set temperature, the processor controls the regulating valve in the indoor unit to be closed. Therefore, the automatic control of the regulating valve can be realized according to the actual situation, and the regulation of the regulating valve according to the temperature regulation rate is continuously carried out under the condition that the indoor environment temperature meets the actual requirement. Considering that the ambient temperature in the room fluctuates within a normal range, the ambient temperature reaching the set temperature may be a target temperature range reaching around the set temperature. And after the processor controls the regulating valve in the indoor unit to be closed, continuously monitoring the environmental temperature, and if the environmental temperature exceeds a target temperature range near the set temperature, controlling the regulating valve in the indoor unit to be opened by the processor, and continuously monitoring the temperature regulating rate.
As shown in connection with fig. 3, an embodiment of the present disclosure provides another method for controlling an air conditioner, including:
s301, the processor obtains the temperature regulation rate of the space where each indoor unit is located.
S302, the processor calculates the average temperature regulation rate according to the temperature regulation rate in the space where each indoor unit is located.
S303, the processor determines a target rate range according to the average temperature adjustment rate.
S304, when the temperature regulation rate in the space where the indoor unit is located is not in the target rate range, the processor regulates the opening of the regulating valve in the indoor unit so that the temperature regulation rate approaches the target rate range.
Therefore, the average temperature regulation rate is determined according to the temperature regulation rate in the space where each indoor unit is located, the target rate range can be ensured to be suitable for the current air conditioner, and the accuracy of the target rate range is improved, so that whether the refrigerant quantity in each indoor unit is more or less is judged more accurately.
Optionally, the processor determines the target rate range based on the average temperature adjustment rate, including: the processor determines the sum of the average temperature adjustment rate and the correction value as the upper limit value of the target rate range, and determines the difference between the average temperature adjustment rate and the correction value as the lower limit value of the target rate range. The target speed range is defined, and the indoor units with too much or too little refrigerant can be accurately screened out.
Optionally, the correction value is in the range of [0,3 ℃/min ]. For example 0.5 deg.C/min, 1 deg.C/min, 2 deg.C/min, or 3 deg.C/min. Preferably 0.5 deg.c/min.
The indoor units related in the calculation process of the embodiment of the disclosure are all indoor units in a starting operation state, and the indoor units in a standby or shutdown state are not related. And under the condition that the number of the indoor units in the running state is changed, calculating the average temperature regulation rate again, and determining the target rate range again according to the updated average temperature regulation rate so as to ensure the accuracy of the target rate range. If the number of the indoor units is changed due to the new increase of the indoor units, controlling the regulating valve in the new increase of the indoor units to operate at the initial opening, and updating and calculating the target rate range in the operation process.
Optionally, after the processor determines the target rate range according to the average temperature adjustment rate, the method for controlling the air conditioner further includes: the processor adjusts the target rate range of each indoor unit according to the room information in the space where the indoor unit is located. Wherein the room information comprises room area and/or room interior volume. Different practical conditions in the room correspond to different temperature regulation requirements, and more or less refrigerants are distributed in part of the indoor units, so that the temperature regulation requirements in the space where the indoor units are located can be met. Therefore, the target speed range is adjusted according to the room information, so that the refrigerant distribution effect is improved, and the temperature regulation result is optimized.
Optionally, the processor adjusts the target rate range of the indoor unit according to the room area, including: the processor increases the target rate range for the indoor unit if the room area is greater than the first area threshold. The processor decreases the target rate range for the indoor unit if the room area is less than the second area threshold. Wherein the first area threshold is greater than or equal to the second area threshold.
Optionally, the processor adjusts the target rate range of the indoor unit according to the room internal volume, including: the processor increases the target rate range for the indoor unit if the room interior volume is greater than the first volume threshold. The processor decreases the target rate range for the indoor unit if the room interior volume is less than the first volume threshold. Wherein the first volume threshold is greater than or equal to the second volume threshold.
The above-mentioned target rate increase range is an overall rate increase range, that is, the upper threshold and the lower threshold of the rate increase range are increased to the same extent at the same time. The above-described reduction target rate range is an overall reduction rate range, that is, the upper limit threshold and the lower limit threshold of the rate range are reduced to the same extent at the same time. While the difference between the upper and lower thresholds of the target frequency range remains unchanged.
As shown in connection with fig. 4, an embodiment of the present disclosure provides another method for controlling an air conditioner, including:
s401, the processor obtains the temperature regulation rate in the space where each indoor unit is located.
S402, the processor obtains a target rate range.
S403, the processor determines whether the temperature adjustment rate is within the target rate range.
If yes, the processor continues to execute step S401; if not, the processor executes step S404.
S404, the processor judges whether the temperature regulation rate in the space where the indoor unit is located is lower than the lower threshold value of the target rate range.
If yes, the processor executes step S405; if not, the processor executes step S406.
S405, the processor increases the opening of the regulating valve in the indoor unit.
S406, the processor reduces the opening of the regulating valve in the indoor unit.
Optionally, the processor increases the opening of the regulating valve in the indoor unit, including: the processor controls the opening of the regulating valve to increase at a first rate such that the temperature regulation rate is within the target rate range. Specifically, the opening degree of the regulating valve may be increased at the first rate until the temperature regulation rate is greater than or equal to the lower limit threshold value of the target rate range, or until the temperature regulation rate reaches the set rate within the target rate range.
Optionally, the first rate has a value in the range of 0 to 10 steps per minute. May be 0,3 steps per minute, 5 steps per minute, 8 steps per minute or 10 steps per minute. Preferably 3 steps per minute, i.e. the opening of the regulating valve is increased by 3 steps per minute. Therefore, the situation that the first speed is too high to cause too high adjustment speed and the opening degree is excessively adjusted is avoided. And when the value of the first rate obtained by calculation exceeds the value range, determining the value of the first rate as a threshold value of the value obtained by calculation in the value range.
Optionally, the determining of the first rate includes: the processor obtains a difference between the rate of temperature adjustment of the indoor unit and a target rate range and determines a first rate based on the difference.
Optionally, the processor determines the first rate from the difference, comprising: the processor determines that the first rate is positively correlated with the absolute value of the difference. Thus, the larger the difference between the actual temperature regulation rate and the target rate range is, the faster the opening of the regulating valve increases, the faster the opening of the regulating valve can be regulated, and the temperature regulation rate can be prevented from being regulated to the target rate range only after a long time is consumed.
Further, after the processor determines the first rate, the method further includes: in the process of adjusting the opening of the regulating valve, the processor obtains a real-time temperature regulating rate and corrects the first rate according to the difference between the real-time temperature regulating rate and the target rate range. Specifically, the smaller the difference between the real-time temperature adjustment rate and the target rate range, the processor subtracts the correction value on the basis of the first rate. Therefore, as the temperature regulation rate gradually approaches the target rate range, the regulation rate of the regulating valve is correspondingly slowed down, the accuracy of the regulation process is improved, and the situation of excessive opening regulation caused by control hysteresis is avoided.
Optionally, the processor controls the opening of the regulating valve to decrease at the second rate such that the temperature regulation rate is within the target rate range. Specifically, the processor controls the opening degree of the regulating valve to decrease at the second rate. Until the rate of temperature adjustment decreases below the upper threshold of the target rate range, or until the rate of temperature adjustment decreases to a preset value within the target rate range.
Optionally, the determining manner of the second rate includes: the processor obtains a difference between the rate of temperature adjustment of the indoor unit and the target rate range and determines a second rate based on the difference.
Optionally, the processor determines the second rate from the difference, comprising: the processor determines that the second rate is positively correlated with the difference. The larger the difference between the temperature regulation rate of the indoor unit and the target rate range is, the larger the reduction rate of the opening of the regulating valve is, so that the regulation rate can be regulated according to actual regulation requirements, and the too fast or too slow regulation is avoided.
Optionally, the second rate has a value in the range of 0 to 10 steps per minute. May be 0,3 steps per minute, 5 steps per minute, 8 steps per minute or 10 steps per minute. Preferably 3 steps per minute, i.e. the opening of the regulating valve is reduced by 3 steps per minute. Therefore, the excessive value of the second speed is avoided, the adjusting speed is too high, and the opening degree is excessively adjusted. And when the value of the first rate obtained by calculation exceeds the value range, determining the value of the first rate as a threshold value of the value obtained by calculation in the value range.
Further, after the processor determines the second rate, the method further includes: in the process of adjusting the opening of the regulating valve, the processor obtains a real-time temperature regulating rate and corrects the second rate according to the difference between the real-time temperature regulating rate and the target rate range. Specifically, the smaller the difference between the real-time temperature adjustment rate and the target rate range, the processor subtracts the correction value on the basis of the second rate. Therefore, as the temperature regulation rate gradually approaches the target rate range, the regulation rate of the regulating valve is correspondingly slowed down, the accuracy of the regulation process is improved, and the situation of excessive opening regulation caused by control hysteresis is avoided.
