图1是根据一示例性实施例示出的一种用于控制立式空调风机转速的方法的流程图。如图1所示,包括:
步骤S101,根据所述净化装置的位置计算风机转速补偿值。
在本实施例中,提供了一种控制方法,通过提高风机转速的方式来补偿因净化装置部分或全部覆盖空调进风口时造成的空调进风口处的进风量降低。其中,净化装置设置在立式空调的进风口位置,净化装置在电机驱动下发生位置变化。
首先,根据净化装置的位置来计算风机转速的补偿值。风机转速的补偿值计算有多种方式。第一种可选地实施方式,以初始风机转速为基准值,则当净化装置处于关闭位置时,风机转速的补偿值为正值;当净化装置处于打开位置时,风机转速的补偿值为零。需要说明的是,初始风机转速由用户设置的空调风速决定,如:用户设定空调风速为高速时,风机转速为1500r/min(转/分钟);用户设定空调风速低速时,风机转速为500r/min(转/分钟)。
第二种可选地实施方式,以在净化装置的位置发生变化前的风机转速为基准值,则当净化装置由打开位置变化到关闭位置时,风机转速的补偿值为正值;则当净化装置由关闭位置变化到打开位置时,风机转速的补偿值为负值。
步骤S102,根据所述风机转速补偿值调整所述立式空调风机转速。
本实施例提供的空调制方法,在净化装置位置发生变化时,首先根据净化装置的位置计算风机转速补偿值,进而根据风机转速补偿值来调节风机的转速以保持制冷或制热效率。
在本实施例中,根据净化装置的位置计算风机转速补偿值,并根据计算得出的风机转速补偿值调整立式空调风机转速,从而能够补偿因净化装置部分或全部覆盖空调进风口所造成的空调进风口处的进风量降低。
现有技术中公开了多种过滤结构。在一些实施例中,净化装置包括位于上部的子净化装置和位于下部的子净化装置,驱动装置驱动两个子净化装置在竖直方向上沿相反方向运动以在打开位置和关闭位置之间切换。
在另一些实施例中,在净化装置由关闭位置切换至打开位置的过程中,净化装置沿着立式空调壳体周向转动。
在另一些实施例中,净化装置包括两个子净化装置。在净化装置由关闭位置切换至打开位置的过程中,两个子净化装置向相互远离的方向沿立式空调周向转动。
前述任一实施例所述的过滤结构中,净化装置在关闭位置时会完全覆盖进风口,根据空气质量不同,净化装置可以不同程度的覆盖进风口,例如:当空气质量稍好一些时,净化装置只覆盖进风口截面面积的二分之一;当空气质量稍差一些时,净化装置覆盖进风口截面面积的四分之三。
此时,确定风机转速补偿值时根据净化装置的位置确定净化装置对进风口的覆盖面积,并根据净化装置对进风口的覆盖面积确定风机转速补偿值或者根据净化装置与进风口之间的相对位置确定风机转速补偿值。具体的,通过公式(1)确定风机转速补偿值:
f’=k×S f/S         (1)
其中,f’为风机转速补偿值,S f为净化装置对进风口的当前覆盖面积,S为进风口的面积,k为补偿系数。
当风机转速的补偿值计算以净化装置处于打开位置时的风机转速为基准值时,通过公式(2)确定风机的目标转速:
f=f 0+f’        (2)
其中,f为风机的目标转速,f 0为初始风机转速,目标转速即净化装置位置改变后部分或全部覆盖进风口时风机所要达到的转速。
在计算f’时,根据步进电机在净化装置由打开位置开始进行位置变化到达当前位置的运行步数、步进电机的步距和进风口的高度确定净化装置对进风口的覆盖面积S f
在一些实施例中,净化装置对进风口的覆盖面积会由大变小或者由小变大。当风机转速的补偿值计算以在净化装置的位置发生变化时的风机转速为基准值时,若净化 装置对进风口的覆盖面积由小变大,进风口处的进风量变小,为补偿进风量,需要增大风机转速,此时风机转速的补偿值为正值;若净化装置对进风口的覆盖面积由大变小,则进风口处的进风量变大,此时可减小风机转速以节省功耗,此时风机转速的补偿值为负值。具体的,通过公式(3)确定风机转速补偿值:
f’=k×△S/S          (3)
其中,f’为风机转速补偿值,△S为净化装置对进风口的覆盖面积的变化值,其中,△S=S f-S f,S f为净化装置对进风口的当前覆盖面积,S f’为净化装置在位置变化前对进风口的覆盖面积。当覆盖面积由小变大时,△S为正值,当覆盖面积由大变小时,△S为负值,S为进风口的面积,k为补偿系数。
此时,根据步进电机的步进方向、运行步数、步进电机的步距和进风口的高度确定净化装置对进风口的覆盖面积。如:以步进电机带动净化装置由打开位置到关闭位置时的步进方向为正向,最终得出的f’为正值;以步进电机带动净化装置由关闭位置到打开位置时的步进方向为负向,最终得出的f’为负值。
通过公式(4)确定风机的目标转速:
f=f 1+f’         (4)
其中,f为风机的目标转速,f 1为在净化装置的位置发生变化前的风机转速,目标转速即净化装置位置改变后风机所要达到的转速。
在本实施中,根据空气质量的不同,净化装置对进风口的覆盖面积不同,净化装置部分或全部覆盖空调进风口时增大进风口处风阻,造成空调进风口处的进风量降低,根据净化装置对进风口的覆盖面积确定风机转速补偿值,或根据净化装置与进风口之间的相对位置确定风机转速补偿值,进而根据风机转速补偿值对风机转速进行调节,通过提高风机转速的方式来补偿进风口处的进风量,在净化装置对进风口的覆盖面积减小,空调进风口处的进风量增大时,降低风机转速以节省能耗。
现有技术中公开的多种过滤结构,在一些实施例中,在净化装置由关闭位置切换至打开位置的过程中,净化装置沿着立式空调壳体的径向向外平移。
显然,当净化装置由关闭位置发生位置改变时,则净化装置并不会对进风口造成覆盖,但其仍阻挡了与进风口方向垂直方向的风,导致进风口的风量减小。随着净化装置的平移,净化装置与进风口之间的距离越大,进风口出的风量越大。
此时,根据净化装置与进风口之间的距离确定风机转速补偿值。当净化装置与进风口之间的距离越大,风机转速补偿值越小;当净化装置与进风口之间的距离越小,风机转速补偿值越大。
在另一些实施例中,净化装置包括两个并排设置的子净化装置,两个子净化装置的一侧相对立式空调可枢转地设置。在净化装置由关闭位置切换至打开位置的过程中,驱动装置驱动每个子净化装置绕该每个子净化装置的一侧向远离立式空调的方向转动。
更优选地,两个子净化装置的相邻的一侧分别设置有一个转轴,驱动装置可通过转轴驱动子净化装置转动,从而使这两个子净化装置发生转动,处于打开位置时,子净化装置与进风口之间有一个夹角。当所述夹角越大,进风口的风量越大。
此时,根据净化装置与进风口之间的距离确定风机转速补偿值。当净化装置与进风口之间的夹角越大,所述风机转速的补偿值越小;当净化装置与进风口之间的夹角越小,所述风机转速的补偿值越小。
在本实施中,净化装置与进风口的距离或夹角不同,进风口的风量大小不同,根据净化装置与进风口之间的距离确定风机转速补偿值,或根据净化装置与进风口之间的夹角确定风机转速补偿值,进而根据风机转速补偿值对风机转速进行调节,通过提高风机转速的方式来补偿进风口处的进风量。
