技术领域

背景技术
多联机空调俗称“一拖多”,多联机空调是一台室外机连接多台室内机,每台室内机可以自由地运转/停止、或群组、或集中等控制。在冷热交替季节,多联机空调中,室内机的运行模式容易出现混合模式,例如:一个室内机制冷模式运行,而另外两个室内机制热模式运行,由于室内机都与室外机连接,因此,产生了冲突,室外机只能按照一种模式进行运行。
目前,可采用先入优先的方式,控制室外机运行,即按照室内机的开机顺序锁定室外机的运行模式,例如:最小开启的室内机是制冷模式运行,不管后面开启的室内机是制热模式还是制冷模式,室外机都按照制冷模式进行运行。或者,预先设定优先级,根据设定的优先级来控制室外机的运行。这些方式控制方式比较简单,但是没有考虑多数用户的控制需求,不能自动适应实际使用场景,可能一台室内机的运行模式限制了其它所有用户的控制需求,因此,多联机空调的智能性和自适应性还有待提高。

本公开实施例中,多联机空调中室内机运行模式不完全相同时,可根据制冷模式运行室内机对应的室内温湿度,确定对应的制冷负荷,并得到总制冷负荷,以及根据制热模式运行室内机对应的室内外温度,以及受室外温度影响的湿度因素,确定对应的制热负荷,并得到总制热负荷,然后,可根据总制冷负荷和总制热负荷,得到冷热负荷率,并根据冷 热负荷率,控制空调的室外机运行,这样,综合制冷负荷和制热负荷,确定空调室外机的运行模式,自动适用实际应用场景,提高了多联机空调的智能性和自适应性。并且,确定不同的负荷时,对应不同的室内湿度或室外湿度的影响,充分考虑用户体感,空调特性,能够更加准确确定出负荷,进而进行准确控制,进一步提高了空调的性能以及智能性。
图1是本公开实施例提供的一种多联机空调的结构示意图。如图1所示,多联机空调包括:外机和多个内机,即室外机和多个室内机。每个室内机都与室外机连接,这样,在一些场景中,例如冷热交替季节,有的室内机可能是制冷模式运行,有的室内机是制热模式运行。例如:图1中的内机1制热模式运行,而内机2和内机3都是制冷模式运行,由于内机都与外机连接,为减少运行冲突,本公开实施例中,可根据室内机对应的总制冷负荷和总制热负荷,确定室外机对应的运行模式,并控制运行。
图2是本公开实施例提供的一种用于多联机空调控制方法的流程示意图。如图2所示,多联机空调的控制过程包括:
步骤201:根据处于制冷运行状态的每个第一室内机对应的当前室内温湿度,确定每个第一室内机对应的制冷负荷,并得到总制冷负荷。
步骤202:根据处于制热运行状态的每个第二室内机对应的当前室内温度,以及室外湿度修正值,确定每个第二室内机对应的制热负荷,并得到总制热负荷。
步骤203:根据总制冷负荷和总制热负荷,得到冷热负荷率,并根据冷热负荷率,控制空调的室外机运行。
多联机空调包括:室外机和多个室内机,每个室内机都与室外机连接。本公开实施例的应用场景中,有的室内机处于制冷运行状态,有的室内机处于制热状态,而室外机的当前运行模式可能是制冷模式或制热模式。因此,可获取处于制冷运行状态的每个第一室内机对应的制冷负荷,并得到总制冷负荷,并获取处于制热运行的每个第二室内机对应的制热负荷,并得到总制热负荷,从而,可根据总制冷负荷和总制热负荷,智能识别出室外机的最佳运转模式。
其中,空调确定每个第一室内机对应的制冷负荷的方式可以有多种,例如:将任意一个第一室内机确定为第一当前室内机,可获取第一当前室内机对应的当前室内温度Tai和当前功率IUHP,从而,可将(Tai-Tset)*IUHP,确定为对应的制冷负荷CoolLoad。其中,Tset为设定目标温度。
但是,空调室内机制冷状态运行时,用户对室内的湿度比较敏感。如夏天相同的温度,但湿度越大,用户越不舒适,因此,在一些实施例中,确定每个第一室内机对应的制冷负荷包括:获取第一当前室内机对应的当前室内温度Tai,当前室内湿度Hum,以及当前功 率IUHP,然后,根据当前室内温度Tai、当前室内湿度Hum,当前功率IUHP,确定第一当前室内机的当前制冷负荷。其中,当前制冷负荷CoolLoad=((Tai-Tset)*x+(Hum-HumSet)*y)*IUHP。x为温度对应的第一权重,y为湿度对应的第二权重,且x+y=1。
可见,可根据室内温度和湿度,来确定制冷运行状态室内机的制冷负荷,提高了确定制冷负荷的准确性。并且,在空调室内机制冷运行状态时,室外温度也会影响室内机对应的制冷负荷,其中,室外温度越高,相同设定目标温度下,同一个室内机的制冷负荷就会越大,因此,在确定制冷负荷时,还可考虑室外温度对制冷负荷的影响,即制冷负荷修正值。在一些实施例中,确定每个第一室内机对应的制冷负荷包括:获取第一当前室内机对应的当前室内温度Tai,当前室内湿度Hum,以及当前功率IUHP,并确定与当前室外温度Tao对应的当前制冷负荷修正值CoolOutRate;根据当前室内温度Tai、当前室内湿度Hum,当前功率IUHP,以及当前制冷负荷修正值CoolOutRate,通过公式(1),确定第一当前室内机的当前制冷负荷。
CoolLoad=[((Tai-Tset)*x+(Hum-HumSet)*y)*IUHP]*CoolOutRate    (1)
其中,CoolLoad为制冷负荷,Tset为设定目标温度,x为温度对应的第一权重,y为湿度对应的第二权重,且x+y=1,CoolOutRate的取值范围为[0,1]。
由于当前制冷负荷修正值CoolOutRate与当前室外温度Tao对应,在一些实施例中,确定与当前室外温度Tao对应的当前制冷负荷修正值CoolOutRate包括:根据保存的室外温度范围与制冷负荷修正值之间的对应关系,确定与当前室外温度Tao对应的当前制冷负荷修正值CoolOutRate。或者,在一些实施例中,确定与当前室外温度Tao对应的当前制冷负荷修正值CoolOutRate包括:根据设定最低室外温度,设定最高室外温度,以及分别对应的制冷取值范围端点值,生成制冷负荷斜率,并根据制冷负荷斜率,以及当前室外温度Tao,得到当前制冷负荷修正值CoolOutRate。
得到每个第一室内机对应的制冷负荷之后,可将每个制冷负荷相加得到对应的总制冷负荷。即总制冷负荷CoolLoad总=∑CoolLoad。
在运行过程中,多联机空调不仅需要获取总制冷负荷,还需要获取处于制热状态运行的第二室内机对应的总制热负荷。同样,空调确定每个第二室内机对应的制热负荷的方式也可以有多种。其中,在一些实施例中,可获取第二当前室内机对应的当前室内温度Tai和当前功率IUHP,从而,可(Tai-Tset)*IUHP,确定为对应的制热负荷HeadLoad。其中,Tset为设定目标温度。
空调室内机处于制热运行状态时,可不考虑室内湿度,但要考虑室外湿度,即空调室 外机对室外湿度比较敏感,容易出现结霜,因此,在确定制热负荷,需要考虑室外湿度,而室外湿度是根据室外温度确定的。并且,室外温度也会影响室内机对应的制热负荷,其中,室外温度越低,相同设定目标温度下,同一个室内机的制热负荷就会越大,因此,在一些实施例中,确定每个第二室内机对应的制热负荷包括:获取第二当前室内机对应的当前室内温度Tai以及当前功率IUHP,并确定与当前室外温度Tao对应的当前室外湿度修正值OutHumRate和当前制热负荷修正值HeatOutRate;根据当前室内温度Tai,当前功率IUHP,当前制热负荷修正值HeatOutRate以及当前室外湿度修正值OutHumRate,通过公式(2),确定当前制热负荷。
HeadLoad=[(Tset-Tai)*IUHP]*HeatOutRate*OutHumRate     (2)
其中,HeadLoad为制热负荷,Tset为设定目标温度,HeatOutRate的取值范围为[0,1]。
并且,在一些实施例中,确定与当前室外温度Tao对应的当前室外湿度修正值OutHumRate和当前制热负荷修正值HeatOutRate包括:根据保存的室外温度范围与制热负荷修正值、室外湿度修正值之间的对应关系,分别确定与当前室外温度Tao对应的当前室外湿度修正值OutHumRate和当前制热负荷修正值HeatOutRate。
或者,在一些实施例中,确定与当前室外温度Tao对应的当前制热负荷修正值HeatOutRate包括:根据设定最低室外温度,设定最高室外温度,以及分别对应的制热取值范围端点值,生成制热负荷斜率,并根据制热负荷斜率,以及当前室外温度Tao,得到当前制热负荷修正值HeatOutRate。
表1是本实施例提供的一种室外温度与负荷修正值之间的对应关系。
表1
例如:若当前室外温度为18℃,根据表1,可确定当前制冷负荷修正值CoolOutRate可为0.4,而当前制热负荷修正值HeatOutRate可为0.6。而根据表2,可确定当前室外湿度修正值OutHumRate可为1。
当然,得到每个第二室内机对应的制热负荷之后,可将每个制热负荷相加得到对应的总制热负荷。即总制热负荷HeadLoad总=∑HeadLoad。
表2是本实施例提供的一种室外温度与室外湿度修正值之间的对应关系。
表2
而得到总制冷负荷和总制热负荷后,可确定室外机对应的运行模式并进行对应的控制, 即根据总制冷负荷和总制热负荷,得到冷热负荷率,并根据冷热负荷率,控制空调的室外机运行。其中,在一些实施例中,得到冷热负荷率包括:将总制冷负荷与总制热负荷相加,得到总负荷;将总制冷负荷与总负荷之间的比例值,确定为第一负荷率,或,将总制热负荷与总负荷之间的比例值,确定为第二负荷率。
例如:第一负荷率coolRate=CoolLoad总/(CoolLoad总+HeadLoad总)。或者,第二负荷率HeadRate=HeadLoad总/(CoolLoad总+HeadLoad总)。
这样,根据第一负荷率控制空调的室外机运行包括:在第一负荷率小于第一设定阈值的情况下,控制空调的室外机进行制热模式运行;在第一负荷大于第二设定阈值的情况下,控制空调的室外机进行制冷模式运行;在第一负荷大于或等于第一设定阈值,且小于或等于第二设定阈值的情况下,控制空调的室外机维持当前模式运行。
其中,第一设定阈值可为35%、40%、或45%;而第二设定阈值可为55%、60%、或65%等等,可根据多联机空调的性能,使用场景等等来确定。
例如:coolRate<35%时,则可控制室外机进行制热模式运行,而coolRate>65%时,则可控制室外机进行制冷模式运行。35%≤coolRate≤65%时,则可控制室外机的运行模式不变,即控制空调的室外机维持当前模式运行。
当然,在一些实施例中,可根据第二负荷率控制空调的室外机运行包括:在第二负荷率小于第三设定阈值的情况下,控制空调的室外机进行制冷模式运行;在第二负荷大于第四设定阈值的情况下,控制空调的室外机进行制热模式运行;在第二负荷大于或等于第三设定阈值,且小于或等于第四设定阈值的情况下,控制空调的室外机维持当前模式运行。同样,第三设定阈值和第四设定阈值可根据多联机空调的性能,使用场景等等来确定,具体不详细阐述了。
可见,本实施例中,多联机空调得到制冷模式运行的室内机总制冷负荷和制热模式运行的室内机的总制热负荷,然后,可根据总制冷负荷和总制热负荷,得到冷热负荷率,并根据冷热负荷率,控制空调的室外机运行,这样,综合制冷负荷和制热负荷,确定空调室外机的运行模式,自动适用实际应用场景,提高了多联机空调的智能性和自适应性。并且,确定不同的负荷时,对应不同的室内湿度或室外湿度的影响,充分考虑用户体感,空调特性,能够更加准确确定出负荷,从而进行准确控制,进一步提高了空调的性能以及智能性。
下面将操作流程集合到具体实施例中,举例说明本发明实施例提供的用于多联机空调控制过程。
本公开一实施例中,多联机空调包括:一个室外机和多个室内机。每个室内机都与室外机连接。并且,空调中保存了如同表1和表2所示的对应关系。并且,第一设定阈值为 40%,第二设定阈值为60%。

步骤303:空调根据当前室内温度Tai、当前室内湿度Hum,当前功率IUHP,以及当前制冷负荷修正值CoolOutRate,通过公式(1),确定第一当前室内机的当前制冷负荷CoolLoad。
CoolLoad=[((Tai-Tset)*x+(Hum-HumSet)*y)*IUHP]*CoolOutRate    (1)
其中,CoolLoad为制冷负荷,Tset为设定目标温度,x为温度对应的第一权重,y为湿度对应的第二权重,且x+y=1,这里,x=0.7,y=0.3。

其中,CoolLoad为制冷负荷,Tset为设定目标温度,x为温度对应的第一权重,y为湿度对应的第二权重,且x+y=1,CoolOutRate的取值范围为[0,1]。
在一些实施例中,第一获取确定单元,具体被配置为根据保存的室外温度范围与制冷负荷修正值之间的对应关系,确定与当前室外温度Tao对应的当前制冷负荷修正值CoolOutRate;或,根据设定最低室外温度,设定最高室外温度,以及分别对应的制冷取值范围端点值,生成制冷负荷斜率,并根据制冷负荷斜率,以及当前室外温度Tao,得到当前制冷负荷修正值CoolOutRate。
在一些实施例中,制热负荷确定模块420包括:
第二获取确定单元,被配置为获取第二当前室内机对应的当前室内温度Tai以及当前功率IUHP,并确定与当前室外温度Tao对应的当前室外湿度修正值OutHumRate和当前制热负荷修正值HeatOutRate。
第二负荷确定单元,被配置为根据当前室内温度Tai,当前功率IUHP,当前制热负荷修正值以及当前室外湿度修正值OutHumRate,通过公式(2),确定当前制热负荷。
HeadLoad=[(Tset-Tai)*IUHP]*HeatOutRate*OutHumRate     (2)
其中,HeadLoad为制热负荷,Tset为设定目标温度,HeatOutRate的取值范围为[0,1]。
在一些实施例中,第二获取确定单元,具体被配置为根据保存的室外温度范围与制热负荷修正值、室外湿度修正值之间的对应关系,分别确定与当前室外温度Tao对应的当前室外湿度修正值OutHumRate和当前制热负荷修正值HeatOutRate;或,根据设定最低室外温度,设定最高室外温度,以及分别对应的制热取值范围端点值,生成制热负荷斜率,并根据制热负荷斜率,以及当前室外温度Tao,得到当前制热负荷修正值HeatOutRate。
在一些实施例中,控制模块430包括:
负荷率确定单元,被配置为将总制冷负荷与总制热负荷相加,得到总负荷;
将总制冷负荷与总负荷之间的比例值,确定为第一负荷率,或,将总制热负荷与总负荷之间的比例值,确定为第二负荷率。
在一些实施例中,控制模块430包括:
控制单元,被配置为在第一负荷率小于第一设定阈值的情况下,控制空调的室外机进行制热模式运行;在第一负荷大于第二设定阈值的情况下,控制空调的室外机进行制冷模式运行;在第一负荷大于或等于第一设定阈值,且小于或等于第二设定阈值的情况下,控制空调的室外机维持当前模式运行。
下面结合实施例进一步描述用于多联机空调控制装置的多联机空调控制过程。
本实施例中,多联机空调包括:一个室外机和多个室内机,并保存了如同表1和表2所示的对应关系。并且,第一设定阈值为40%,第二设定阈值为60%。
图5是本公开实施例提供的一种用于多联机空调控制装置的结构示意图。如图5所示,用于多联机空调控制装置400包括:制冷负荷确定模块410、制热负荷确定模块420和控制模块430,其中,制冷负荷确定模块410包括:第一获取确定单元411和第一负荷确定单元412。制热负荷确定模块420包括:第二获取确定单元421和第二负荷确定单元422。控制模块430包括:负荷率确定单元431和控制单元的432。
本实施例中,多联机空调运行过程中,获取了当前室外温度Tao,这样,将一个制冷运行状态的第一室内机确定为第一当前室内机之后,制冷负荷确定模块410中的第一获取确定单元411可获取第一当前室内机作用区域内的当前室内温度Tai,当前室内湿度Hum,以及当前功率IUHP,并根据表1,确定与当前室外温度Tao对应的当前制冷负荷修正值CoolOutRate;从而,第一负荷确定单元412可根据当前室内温度Tai、当前室内湿度Hum,当前功率IUHP,以及当前制冷负荷修正值CoolOutRate,通过公式(1),确定第一当前室内机的当前制冷负荷CoolLoad。
CoolLoad=[((Tai-Tset)*x+(Hum-HumSet)*y)*IUHP]*CoolOutRate    (1)
其中,CoolLoad为制冷负荷,Tset为设定目标温度,x为温度对应的第一权重,y为湿度对应的第二权重,且x+y=1,这里,x=0.7,y=0.3。
这样,所有的第一室内机都确定过第一当前室内机,即所有第一室内机已轮询,制冷负荷确定模块410将每个制冷负荷相加得到对应的总制冷负荷。总制冷负荷CoolLoad总=∑CoolLoad。
并且,可将处于制热运行状态的一个第二室内机确定为第二当前室内机,从而,制热负荷确定模块420中的第二获取确定单元421可获取第二当前室内机作用区域内的当前室内温度Tai,以及当前功率IUHP,并根据表1,确定与当前室外温度Tao对应的当前制热负荷修正值HeadOutRate,以及根据表2,确定与当前室外温度Tao对应的当前室外湿度修正值OutHumRate。并且,第二负荷确定单元422根据当前室内温度Tai,当前功率IUHP,当前制热负荷修正值HeatOutRate以及当前室外湿度修正值OutHumRate,通过公式(2),确定当前制热负荷。
HeadLoad=[(Tset-Tai)*IUHP]*HeatOutRate*OutHumRate     (2)
其中,HeadLoad为制热负荷,Tset为设定目标温度
这样,所有的第二室内机已轮询之后,制热负荷确定模块420可将每个制热负荷相加 得到对应的总制热负荷。总制热负荷HeadLoad总=∑HeadLoad。
从而,控制模块430中的负荷率确定单元431可将总制冷负荷与总制热负荷相加,得到总负荷,并将总制冷负荷与总负荷之间的比例值,确定为第一负荷率。第一负荷率coolRate=CoolLoad总/(CoolLoad总+HeadLoad总)。
若coolRate<40%时,控制单元432可控制室外机以制热模式进行运行;coolRate>60%时,控制单元432可控制室外机以制冷模式进行运行;而若40%≤coolRate≤60%时,控制单元432可控制室外机保持当前模式进行运行。
可见,本实施例中,多联机空调中运行时,综合考虑影响室内外环境温度、湿度的影响,从而,用于多联机空调控制的装置可得到制冷模式运行的室内机总制冷负荷和制热模式运行的室内机的总制热负荷,然后,可根据总制冷负荷和总制热负荷,得到冷热负荷率,并根据冷热负荷率,控制空调的室外机运行,这样,综合制冷负荷和制热负荷,确定空调室外机的运行模式,自动适用实际应用场景,提高了多联机空调的智能性和自适应性。并且,确定不同的负荷时,对应不同的室内湿度或室外湿度的影响,充分考虑用户体感,空调特性,能够更加准确确定出负荷,从而进行准确控制,进一步提高了空调的性能以及智能性。
