具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容,下面结合附图对本公开实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本公开实施例。在以下的技术描述中,为方便解释起见,通过多个细节以提供对所披露实施例的充分理解。然而,在没有这些细节的情况下,一个或多个实施例仍然可以实施。在其它情况下,为简化附图,熟知的结构和装置可以简化展示。
本公开实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本公开实施例的实施例。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含。
除非另有说明,术语“多个”表示两个或两个以上。
本公开实施例中,字符“/”表示前后对象是一种“或”的关系。例如,A/B表示:A或B。
术语“和/或”是一种描述对象的关联关系,表示可以存在三种关系。例如,A和/或B,表示:A或B,或,A和B这三种关系。
目标排气温度,是决定节流元件开度的参数之一,按照目标排气温度调节节流元件开度,能够使制冷剂流量处于更优状态。
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,与实际目标排气温度值存在偏差,减弱了空调运行效果。为了进一步提高空调性能,需要对目标排气温度进行自适应调节,使目标排气温度与实际的最佳目标排气温度更接近,空调以更好状态运行。
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,以实现对上述空调的控制,该方法包括:
步骤S01,获取与第一目标排气温度相对应的第一性能系数。
这里,可以通过空调运行参数和室外环境参数确定第一目标排气温度,通过空调性能参数确定第一性能系数。
可选地,第一目标排气温度的确定,包括:获取第一排气温度时刻空调的压缩机运行频率;获取第一排气温度时刻室外环境温度补偿值;根据空调的压缩机运行频率与室外环境温度补偿值确定第一目标排气温度。如此,确定第一目标排气温度为修正对象,以得到更佳的目标排气温度。
这里,压缩机运行频率是指在第一排气温度时刻下,压缩机的实际运行频率。对于具体如何获取压缩机的实际运行频率可参见相关技术,在此不做赘述。
室外环境温度补偿值,是指室外环境温度所在的温度区间对应的补偿值。在本公开的实施例中,室外环境温度补偿值为预设值,该预设值可调整。
需要说明的是,在空调不同的工作模式下,不同的室外环境温度对应不同的补偿值。例如,在空调工作模式为制冷模式时,在室外环境温度大于或等于20摄氏度且小 于30摄氏度的情况下,室外环境温度补偿值可以为-5。
具体地,根据空调的压缩机运行频率与室外环境温度补偿值确定第一目标排气温度,可以是依据拟合公式,计算压缩机的目标排气温度。其中,拟合公式是根据设定工况下测试获得的目标排气温度与室外环境温度补偿值、压缩机实际运行频率之间的对应关系确定的。
在一些可选的实施例中,拟合公式为DisT=a*f+b+c;其中,DisT为目标排气温度,f为压缩机运行频率,c为室外环境温度补偿值,a为小数,范围为0.01至2,b为整数,范围为-50至200。
在一具体的实施例中,空调工作模式为制冷模式,压缩机的实际运行频率为60Hz时,室外环境温度为35℃,通过测试得到压缩机的目标排气温度为80℃,当压缩机的实际运行频率变化为70Hz时,该工况下的目标排气温度DisT=a*70+b+c,室外环境温度为35℃时所对应的室外环境温度补偿值c为0,若a=1.5,b=10,则在此工况下的目标排气温度为115℃。
此外,第一排气温度时刻,是指排气温度为第一排气温度时所对应的时刻;第一排气温度,用于表述压缩机的一个实际排气温度。
可选地,第一排气温度的确定,包括:在空调压缩机的排气温度初次达到或超过目标排气温度的情况下,获取设定时长内的一个实际排气温度作为第一排气温度。
这里,设定时长用于表述预先设定的一段时间。
如此,在排气温度稳定后选择一个实际排气温度作为第一排气温度,以第一排气温度为基础值进行调节,使目标排气温度的调节更准确,得到的调节后的目标排气温度更有实际意义。
可选地,获取与第一目标排气温度相对应的第一性能系数,包括:获取第一排气温度时刻空调的能力比功率;根据能力比功率确定第一性能系数。
如此,将能力与功率的比值作为性能系数,性能系数反映了能源效率,性能系数越大,说明空调的能源效率越高。
这里,性能系数用于表述空调的能源效率;第一性能系数是空调的能力与功率之比。对于具体如何获取第空调的能力与功率可参见相关技术,在此不做赘述。
步骤S02,获取第一目标排气温度的多个修正值,并获取与多个修正值对应的修正性能系数。
这里,修正值用于表述通过对第一目标排气温度加或减至少一个修正量得到的目 标排气温度。这里,修正量可以是固定修正量或可变修正量。作为一种示例,修正量是固定修正量,例如,修正量可以是0.5℃。
可选地,获取第一目标排气温度的多个修正值,并获取与修正值对应的修正性能系数,包括:
负向修正第一目标排气温度,获取第一负向修正值,并控制空调根据第一负向修正值运行,以获取第一负向修正性能系数。如此,得到小于第一目标排气温度且与第一目标排气温度数值接近的目标排气温度所对应的性能系数。
正向修正第一目标排气温度,获取第一正向修正值,并控制空调根据第一正向修正值运行,以获取第一正向修正性能系数。如此,得到大于第一目标排气温度且与第一目标排气温度数值接近的目标排气温度所对应的性能系数。
这里,负向修正是指对第一目标排气温度减一个修正量;正向修正是指对第一目标排气温度加一个修正量。
可选地,对第一目标排气温度的负向修正还包括:在第一负向修正性能系数大于第一性能系数的情况下,负向修正第一负向修正值,获取第二负向修正值,并控制空调根据第二负向修正值运行,以获取第二负向修正性能系数。
如此,在第一负向修正性能系数大于第一性能系数的情况下,对第一目标排气温度减两个修正量,以获取更多的比第一性能系数大的性能系数。
可选地,对第一目标排气温度的正向修正还包括:在第一正向修正性能系数大于第一性能系数的情况下,正向修正第一正向修正值,获取第二正向修正值,并控制空调根据第二正向修正值运行,以获取第二正向修正性能系数。
如此,在第一正向修正性能系数大于第一性能系数的情况下,对第一目标排气温度加两个修正量,以获取更多的比第一性能系数大的性能系数。
需要说明的是,说明书只列举了修正过程的两次条件判断及相应的执行动作,以明确修正过程。只要满足判断条件,修正过程就可以继续进行。例如,在第二正向修正性能系数大于第二性能系数的情况下,正向修正第二正向修正值,获取第三正向修正值,并控制空调根据第三正向修正值运行,以获取第三正向修正性能系数。或者,可以根据实际使用需求,设置修正过程的执行次数,并在达到执行次数的情况下,停止修正过程。
步骤S03,确定与多个修正性能系数中的最大值对应的修正值为第二目标排气温度。
具体地,首先确定多个修正性能系数中的最大值,继而确定最大值对应的修正值 为第二目标排气温度。
步骤S04,根据第二目标排气温度控制空调的运行参数。
这里,运行参数包括节流元件的开度。对于具体如何控制空调的运行参数可参见相关技术,在此不做赘述。
