The target exhaust temperature of an air-conditioning compressor is an important parameter that affects the operating state of the air conditioner.

The calculation logic of the target exhaust temperature is preset, but When the ambient temperature is low and the air conditioner is heating, the surface of the outdoor heat exchanger is prone to frost, and the actual exhaust temperature will decrease as the thickness of the frost layer increases. In order to meet the target exhaust temperature, the valve opening will become smaller, and then Frosting will be more serious and enter a vicious circle, which will eventually lead to large fluctuations in indoor temperature and poor heating effect of air conditioners.

在空气调节领域,一般目标排气温度是根据实验数据和常用环境温度范围事先设置好的,从而不能根据实际环境状况做出适应性改变,减弱了空调运行效果。比如在环境温度低,空调制热的情况下,如果不对目标排气温度进行调节,会使空调频繁化霜,造成室内温度波动。为了使空调机组***运行稳定,需要对目标排气温度进行自适应调节。In the field of air conditioning, the general target exhaust temperature is set in advance according to the experimental data and the common ambient temperature range, so that adaptive changes cannot be made according to the actual environmental conditions, which weakens the operation effect of the air conditioner. For example, when the ambient temperature is low and the air conditioner is heating, if the target exhaust temperature is not adjusted, the air conditioner will defrost frequently, causing the indoor temperature to fluctuate. In order to make the air conditioning unit system operate stably, it is necessary to adjust the target exhaust temperature adaptively.
需要说明的是,下述的公开实施例均是基于空调处于低温环境制热的条件而成立的。It should be noted that the following disclosed embodiments are all established based on the condition that the air conditioner is in a low temperature environment for heating.
基于此,如图1所示,本公开实施例提供一种用于空调的控制方法,该方法包括:Based on this, as shown in FIG. 1 , an embodiment of the present disclosure provides a control method for an air conditioner, the method comprising:
步骤S01,确定压缩机的排气温度达到目标排气温度后,继续采集压缩机的新的排气温度。Step S01, after it is determined that the exhaust gas temperature of the compressor reaches the target exhaust gas temperature, continue to collect the new exhaust gas temperature of the compressor.
这里,排气温度指的是压缩机的实际排气温度;新的排气温度指的是变化后的实际排气温度。对于如何采集实际排气温度可参考相关技术,在此不做赘述。Here, the discharge temperature refers to the actual discharge temperature of the compressor; the new discharge temperature refers to the changed actual discharge temperature. For how to collect the actual exhaust gas temperature, reference may be made to related technologies, which will not be repeated here.
采集压缩机的排气温度,可以是按照预设采样周期采集实际排气温度,也可以是实时采集实际排气温度,此处不做限制。The collection of the exhaust gas temperature of the compressor may be to collect the actual exhaust gas temperature according to a preset sampling period, or to collect the actual exhaust gas temperature in real time, which is not limited here.
步骤S02,根据预设控制周期,确定在当前控制周期内采集的新的排气温度对应的当前排气温度变化率。Step S02, according to the preset control period, determine the current exhaust gas temperature change rate corresponding to the new exhaust gas temperature collected in the current control period.
这里,预设控制周期是预先设置的,用于表述每经过一个预设控制周期计算一次排气温度变化率;当前控制周期指的是根据预设控制周期的时间长度,采集新的排气温度时的时刻所落入的周期。Here, the preset control period is preset, which is used to express that the rate of change of the exhaust gas temperature is calculated every time a preset control period passes; the current control period refers to collecting a new exhaust gas temperature according to the time length of the preset control period The cycle in which the moment of time falls.
步骤S03,根据排气温度变化率与目标排气温度修正值之间的对应关系,确定当前排气温度变化率对应的当前修正值。Step S03 , according to the corresponding relationship between the exhaust gas temperature change rate and the target exhaust gas temperature correction value, determine the current correction value corresponding to the current exhaust gas temperature change rate.
这里,当前修正值用于表述当前目标排气温度的调节量。Here, the current correction value is used to express the adjustment amount of the current target exhaust gas temperature.
可选地,根据排气温度变化率与目标排气温度修正值之间的对应关系,确定当前排气温度变化率对应的当前修正值,包括:如果a≤K<b,则T=-10*b;如果b≤K<c,则T=-10*c;如果c≤K<d,则T=-10*d;如果d≤K<e,则T=-10*e;其中,K是排气温度变化率,T是目标排气温度修正值,a的范围为0至0.1,b的范围为0.1至0.5,c的范围为0.6至1,d的范围为1至1.5,e的范围为1.5至2。Optionally, according to the corresponding relationship between the exhaust gas temperature change rate and the target exhaust gas temperature correction value, determine the current correction value corresponding to the current exhaust gas temperature change rate, including: if a≤K<b, then T=-10 *b; if b≤K<c, then T=-10*c; if c≤K<d, then T=-10*d; if d≤K<e, then T=-10*e; where, K is the exhaust gas temperature change rate, T is the target exhaust gas temperature correction value, a is in the range of 0 to 0.1, b is in the range of 0.1 to 0.5, c is in the range of 0.6 to 1, d is in the range of 1 to 1.5, e The range is 1.5 to 2.
如此,排气温度变化率越大,目标排气温度修正值越大。排气温度变化率大说明实际排气温度与目标排气温度的差距大,需要减小目标排气温度,此时目标排气温度修正值大,能够减小修正后的目标排气温度与当前的最新排气温度之间的差值。In this way, the larger the exhaust gas temperature change rate, the larger the target exhaust gas temperature correction value. A large change rate of exhaust gas temperature indicates that the gap between the actual exhaust gas temperature and the target exhaust gas temperature is large, and the target exhaust gas temperature needs to be reduced. At this time, the correction value of the target exhaust gas temperature is large, which can reduce the difference between the corrected target exhaust gas temperature and the current The difference between the most recent exhaust temperatures.
这里,a、b、c、d、e为在各自区间范围内取值的随机数。Here, a, b, c, d, and e are random numbers that take values within their respective intervals.
在一些实施例中,a=0.04,b=0.2,c=0.7,d=1.2,e=1.8,在当前排气温度变化率K为0.6时,其大于b且小于c,则其对应的修正值T=-10*0.7=-7,即目标排气温度减小7摄氏度。In some embodiments, a=0.04, b=0.2, c=0.7, d=1.2, e=1.8, when the current exhaust gas temperature change rate K is 0.6, which is greater than b and less than c, the corresponding correction The value T=-10*0.7=-7, ie the target exhaust gas temperature is reduced by 7 degrees Celsius.
在又一些实施例中,a=0.06,b=0.3,c=0.8,d=1.4,e=1.7,在当前排气温度变化率K为0.2时,其大于a且小于b,则其对应的修正值T=-10*0.3=-3,即目标排气温度减小3摄氏度。In still other embodiments, a=0.06, b=0.3, c=0.8, d=1.4, e=1.7, when the current exhaust gas temperature change rate K is 0.2, which is greater than a and less than b, then the corresponding The correction value T=-10*0.3=-3, that is, the target exhaust gas temperature is reduced by 3 degrees Celsius.
可选地,控制方法还包括:Optionally, the control method further includes:
在当前排气温度变化率大于或等于预设变化率的情况下,获取排气温度变化率与目标排气温度修正值之间的对应关系。When the current exhaust gas temperature change rate is greater than or equal to the preset change rate, the corresponding relationship between the exhaust gas temperature change rate and the target exhaust gas temperature correction value is acquired.
这里,预设变化率用于表述一个控制周期内排气温度的数值变化的情况。当排气温度变化率小于该预设变化率时,说明排气温度变化率较小,则实际排气温度与目标排 气温度相差不大;当排气温度变化率大于或等于该预设变化率时,说明排气温度变化率相对较大,则实际排气温度与目标排气温度有较大差距。在本公开实施例中,预设变化率的数值可以为本公开实施例中a的数值,此处a的范围为0至0.1。Here, the preset change rate is used to express the numerical change of the exhaust gas temperature in one control period. When the change rate of the exhaust gas temperature is less than the preset change rate, it means that the change rate of the exhaust gas temperature is small, and the actual exhaust gas temperature is not much different from the target exhaust gas temperature; when the change rate of the exhaust gas temperature is greater than or equal to the preset change rate When the rate of change of exhaust gas temperature is relatively large, it means that the change rate of exhaust gas temperature is relatively large, and there is a large gap between the actual exhaust gas temperature and the target exhaust gas temperature. In the embodiment of the present disclosure, the value of the preset rate of change may be the value of a in the embodiment of the present disclosure, where a ranges from 0 to 0.1.
如此,在实际排气温度与目标排气温度相差不大的时候,不会出现空调频繁化霜导致室内温度波动大的问题,因此不需要修正目标排气温度,可以简化排气温度调节过程,降低功耗。In this way, when the actual exhaust gas temperature is not much different from the target exhaust gas temperature, the problem of frequent defrosting of the air conditioner will not cause large fluctuations in the indoor temperature, so there is no need to correct the target exhaust gas temperature, which can simplify the exhaust temperature adjustment process. Reduce power consumption.
步骤S04,根据当前修正值对目标排气温度进行修正,以减小修正后的目标排气温度与当前控制周期内采集的最新排气温度之间的差值。Step S04, correcting the target exhaust gas temperature according to the current correction value to reduce the difference between the corrected target exhaust gas temperature and the latest exhaust gas temperature collected in the current control period.
可选地,控制方法还包括:在满足换热器化霜条件或节流元件的阀开度调节到最大开度的情况下,停止修正目标排气温度。Optionally, the control method further includes: when the defrosting condition of the heat exchanger is satisfied or the valve opening degree of the throttling element is adjusted to the maximum opening degree, stopping the correction of the target exhaust gas temperature.
这里,节流元件指的是可以调节阀开度的元件,在本公开实施例中节流元件可以是电子膨胀阀。Here, the throttling element refers to an element that can adjust the valve opening degree, and in the embodiment of the present disclosure, the throttling element may be an electronic expansion valve.
如此,在满足换热器化霜条件的情况下,空调已经开始化霜,此时修正目标排气温度不再有意义;在节流元件的阀开度调节到最大开度的情况下,目标排气温度无法继续减小,因此停止修正目标排气温度。In this way, when the defrosting conditions of the heat exchanger are met, the air conditioner has already started to defrost, and it is no longer meaningful to correct the target exhaust gas temperature at this time; when the valve opening of the throttle element is adjusted to the maximum opening, the target The exhaust gas temperature cannot continue to decrease, so the correction of the target exhaust gas temperature is stopped.
可选地,如果按照预设采样周期采集压缩机的新的排气温度,且预设采样周期小于预设控制周期,预设控制周期为预设采样周期的整数倍,则在节流元件的阀开度调节到最大开度的情况下,停止修正目标排气温度,包括:根据当前采样周期下采集的最新排气温度,确定与最新排气温度对应的当前阀开度;如果当前阀开度为节流元件的最大开度,则停止修正目标排气温度。Optionally, if the new exhaust gas temperature of the compressor is collected according to the preset sampling period, and the preset sampling period is smaller than the preset control period, and the preset control period is an integer multiple of the preset sampling period, then in the throttling element When the valve opening is adjusted to the maximum opening, stop correcting the target exhaust temperature, including: determining the current valve opening corresponding to the latest exhaust temperature according to the latest exhaust temperature collected in the current sampling period; If the degree is the maximum opening degree of the throttle element, the correction of the target exhaust gas temperature is stopped.
如此,排气温度的检测频率高,可以根据检测的实时排气温度了解阀开度是否达到最大开度,以及时停止修正目标排气温度,降低功耗。In this way, the detection frequency of the exhaust gas temperature is high, and it is possible to know whether the valve opening degree has reached the maximum opening degree according to the detected real-time exhaust gas temperature, and stop correcting the target exhaust gas temperature in time to reduce power consumption.
可选地,在满足换热器化霜条件的情况下,停止修正目标排气温度,包括:确定当前环境温度下对应的化霜条件;在室外机盘管温度满足化霜条件的情况下,停止修正目标排气温度。Optionally, when the defrosting conditions of the heat exchanger are met, stopping the correction of the target exhaust gas temperature includes: determining the defrosting conditions corresponding to the current ambient temperature; when the temperature of the outdoor unit coil satisfies the defrosting conditions, Stop correcting the target exhaust temperature.
如此,在换热器化霜时,空调停止制热,此时无需修正目标排气温度。In this way, when the heat exchanger is defrosted, the air conditioner stops heating, and it is not necessary to correct the target exhaust gas temperature at this time.
采用本公开实施例提供的用于空调的控制方法,通过获取排气温度和排气温度变化率,可以得知实际排气温度与目标排气温度的差距;根据排气温度变化率所在的数值区间,确定目标排气温度修正值,从而减小实际排气温度与目标排气温度的差距;根据目标排气温度修正值,调节空调的目标排气温度。通过本方案,能够对目标排气温度进 行修正,从而避免了空调频繁化霜造成室内温度波动,使空调机组***运行稳定,空调制热效果好,用户的使用体验好。Using the control method for air conditioning provided by the embodiment of the present disclosure, by obtaining the exhaust gas temperature and the rate of change of the exhaust gas temperature, the difference between the actual exhaust gas temperature and the target exhaust gas temperature can be known; according to the value of the rate of change of the exhaust gas temperature In the interval, the target exhaust temperature correction value is determined, thereby reducing the gap between the actual exhaust temperature and the target exhaust temperature; according to the target exhaust temperature correction value, the target exhaust temperature of the air conditioner is adjusted. Through this solution, the target exhaust temperature can be corrected, thereby avoiding the fluctuation of indoor temperature caused by frequent defrosting of the air conditioner, so that the system of the air conditioner unit operates stably, the heating effect of the air conditioner is good, and the user experience is good.

步骤S11,在压缩机的排气温度达到目标排气温度的情况下,采集设定时长后的压缩机排气温度作为压缩机新的排气温度。In step S11, when the exhaust temperature of the compressor reaches the target exhaust temperature, the exhaust temperature of the compressor after the set time period is collected as the new exhaust temperature of the compressor.
这里,设定时长是预先设置的时间长度,用于表述排气温度变化率较小的状态持续的时间。在未达到设定时长时,排气温度变化率比较小,不修正目标排气温度;在经过设定时长后,排气温度变化率相对较大,需要根据采集的排气温度得到排气温度变化率的数值,从而对目标排气温度进行修正。Here, the set time length is a preset time length, and is used to express the time during which the state in which the rate of change of the exhaust gas temperature is small continues. When the set time is not reached, the change rate of the exhaust temperature is relatively small, and the target exhaust temperature is not corrected; after the set time elapses, the change rate of the exhaust temperature is relatively large, and the exhaust temperature needs to be obtained according to the collected exhaust temperature. The value of the rate of change to correct the target exhaust gas temperature.
在本公开实施例中,设定时长的设置可参考研发阶段典型工况下的实验数据。In the embodiment of the present disclosure, the setting of the set duration may refer to experimental data under typical working conditions in the research and development stage.
步骤S12,根据预设控制周期,确定在当前控制周期内采集的新的排气温度对应的当前排气温度变化率。Step S12, according to the preset control period, determine the current exhaust gas temperature change rate corresponding to the new exhaust gas temperature collected in the current control period.
步骤S13,根据排气温度变化率与目标排气温度修正值之间的对应关系,确定当前排气温度变化率对应的当前修正值。Step S13: Determine a current correction value corresponding to the current exhaust gas temperature change rate according to the corresponding relationship between the exhaust gas temperature change rate and the target exhaust gas temperature correction value.
步骤S14,根据当前修正值对目标排气温度进行修正,以减小修正后的目标排气温度与当前控制周期内采集的最新排气温度之间的差值。Step S14, correcting the target exhaust gas temperature according to the current correction value, so as to reduce the difference between the corrected target exhaust gas temperature and the latest exhaust gas temperature collected in the current control period.
