技术领域
本文涉及空调技术领域,特别涉及一种用于空调自清洁的控制方法及装置、空调。
背景技术
目前,现有家用空调在制冷运行过程中会有大量冷凝水产生,在合适的湿度和温度条件下,会滋生大量的细菌;并且细菌会随着送风输送到房间中去,这样会严重影响用户的舒适性和健康。据相关研究证明,在高湿度或者高温条件下细菌最易滋生。
另外,家用空调器在实际运行过程中,当设定温度和房间温度偏差较大时,压缩机高频运行,此时内机盘管温度一般较低(低于空气露点温度)空气中的水蒸气不断被冷凝下来,当房间温度达到设定温度时,湿度可能已经很低,而一般空调器没有加湿功能,此时用户会感觉干燥不舒服;当房间温度和设定温度差值很小时,空调器大多低频运行,此时内机盘管温度一般较高(高于空气露点温度),空气中的水蒸气不会被冷凝下来,这样当房间温度达到设定温度时候,空气湿度可能偏大,用户同样感觉不舒服。因此,现有的空调控制方法往往不能兼顾对室内温度和湿度调节,导致室内温、湿度不能满足用户的舒适度和健康性的要求。

空调已是日常生活中常见的电器了,可以调节室内的温度,即可升温或降温,使得室内温度与用户预设温度匹配。但是,在温度调节的过程中,往往会导致室内环境湿度的变化,如通过增大冷媒量来降低室内环境温度时,由于室内换热器的表面温度降低,则可能导致流经室内换热器的空气中被冷凝的水汽量增加,这样,会导致室内环境湿度下降,用户往往会产生干燥不适的感觉。同理,在通过空调调节室内的湿度时,也可能会导致室内环境温度的变化,如通过增大冷媒量来降低室内换热器的表面温度,进而对室内环境进去除湿的过程中,由于室内换热器的表面温度降低,则会导致经营室内机吹出的空气的温度下降,这样,会使得室内环境温度降低,用户往往会产生寒冷的感觉。因此,现有的只调节温度或湿度等单一参数的空调控制方法不能满足用户舒适度的要求。
空调导风板的位置包括:最大出风位置和最小出风位置,其中,最大出风位置即导风板处于中间位置,此时导风板对出风口出风的阻力最小。最小出风位置即导风板摆动到对出风口出风的阻力最大的位置,包括导风板所能摆动的最大角度处,此时出风口在导风板的作用下向下吹风,或在完全覆盖出风口之前,此时出风口在导风板的作用下向上吹风。
在本实施例中,最小出风位置即出风口在导风板的作用下向上吹风。保证在调节过程中空调吹出的风不直接吹向人体,同时加快上层空气与下层空气的混合速度,加快调节过程让用户接触到的空气温度适宜。
在一实施例中,一种用于控制空调的方法,包括:在空调制冷模式下,采集室内温度t和室内湿度RH;
当所述室内温度t大于第一预设温度t1时,根据第一控制策略对压缩机的工作 频率和/或室内风机的转速进行控制;
当所述室内温度t小于或等于所述第一预设温度t1时,根据所述室内湿度RH选择相应的控制策略对压缩机的工作频率和/或室内风机的转速进行控制;或者,根据第二控制策略对压缩机的工作频率和导风板的位置进行控制。
在制冷模式下,采集实时的室内温度与室内湿度,综合室内温度与预设温度的大小关系以及室内湿度的大小确定不同的控制策略,兼顾对室内温度和湿度调节,进而对压缩机的工作频率,室内风机的转速或导风板的位置中的一项或多项进行调整,使室内温度和湿度均可以满足用户舒适度的要求,避免因调节单一室内环境参数而导致其它环境参数波动的影响。

空调设置有温度传感器,用于检测室内环境的当前温度值。温度传感器的感应端可以设置于空调的进风口或者机壳外壁上,以使其检测的当前温度值可与室内环境的实际温度相同或相近,从而提高本实施例依据当前室内温度温度值对空调的压缩机工作频率和室内风机的转速调整的精准度。
空调设置有湿度传感器,用于检测室内环境的当前湿度值,也即是本次流程中所获取的实时的室内湿度RH。湿度传感器的感应端可以设置于空调的进风口或者机壳外壁上,以使其检测的当前湿值可与室内环境的实际湿度相同或相近,从而提高本实施例依据当前室内湿度值对空调的压缩机工作频率和室内风机的转速调整的精准度。

在一些实施例中,当用户设定的室内温度T大于K时,所述第一预设温度t1=K+N;当用户设定的室内温度T小于或等于K时,所述第一预设温度t1=K+M;其中,K、N和M为预设的温度值。其中,N大于或等于M。
优选地,K=24℃、25℃或26℃。优选地,N=2.5℃、3℃或3.5℃。优选地,M=1.5℃、2℃或2.5℃。

在一些实施例中,在步骤S203和步骤S204之后还包括:根据压缩机的工作频率或室内风机的转速调整导风板的位置。
图3是根据一示例性实施例示出的一种用于控制空调的方法的流程图。在本实施例中仅针对与前述实施例不同的步骤进行说明。如图3所示,包括:
步骤S301,在空调制冷模式下,采集室内温度t和室内湿度RH。

例如:当K=25℃,N=2.5℃,M=1.5℃,Q=1℃;用户设定的室内温度T为26℃时,第一预设温度t1=26℃+2.5℃=28.5℃,第二预设温度t2=26℃+2.5℃-1℃=27.5℃;用户设定的室内温度T为25℃时,t1=25℃+1.5℃=26.5℃,t2=25℃+1.5℃-1℃=25.5℃。
图4是根据一示例性实施例示出的一种用于控制空调的方法的流程图。如图4所示,包括:

在步骤S402中,室内温度t大于第一预设温度t1,温度偏差较大,需要进行降温,根据第一控制策略对压缩机的工作频率和/或室内风机的转速进行控制,以实现降温。
在步骤S403中,室内温度t小于或等于第一预设温度t1,且大于第二预设温度t2,此时室内温度接近用户设定温度,根据第二控制策略对压缩机的工作频率和导风板的位置进行控制,以降低空调能耗,节约能源。

在前述任一实施例中,优选的,第一预设湿度Rh为52%,经过以大数据的方式进行统计得出黄金湿度值为52%,在该湿度值下,人体舒适度最佳,同时在该湿度下,还可以抑制环境中细菌和霉菌的滋生。
图5是根据一示例性实施例示出的一种用于控制空调的方法的流程图。
在一些实施例中,如图5所示,当所述室内温度t小于或等于所述第二预设温度t2,且所述室内湿度RH大于或等于所述第一预设湿度Rh时,执行步骤S406,根据第四控制策略对压缩机的工作频率和/或室内风机的转速进行控制,当室内温度t大于第三预设温度t3,即t3<t≤t2时,若室内风机的转速R小于或等于设定转速值R’,调整导风板处于最小出风位置位置,若室内风机的转速R大于设定转速值R’,调整导风板处于最大出风位置;当室内温度t小于或等于第三预设温度t3,即t≤t3时,调整室内风机以最大转速运行,调整导风板处于最小出风位置,此时室内温度过低,上层空气温度高,底层空气即人体所接触的空气温度低,调整室内风机以最大转速运行,导风板处于最小出风位置,加快上层空气与下层空气的混合速度,从而让用户接触到的空气温度适宜。
在前述任一实施例中,在根据室内温度t和室内湿度RH对压缩机的工作频率,室内风机的转速或导风板的位置进行控制之前,还包括:接收模式切换指令,并从当前运行模式切换进入第一模式运行。
其中,模式切换指令由空调遥控器,空调室内机上的控制面板或者对空调具有遥控功能的移动终端发出,第一模式为PMV模式。PMV模式是人体舒适智能控制模式,用户在空调遥控器,空调室内机上的控制面板或者对空调具有遥控功能的移动终端上按下PMV模式按键后,空调收到PMV模式指令后将切换进入PMV模式,采集室内温度、室内湿度、风速、热辐射、着衣量、活动量等参数。其中,PMV为人体的热舒适指标值,可以表征为室内空气温度Ta、平均辐射温度Tr、室内空气流速Va、室内空气湿度φa、人体代谢率M、服装热阻CLO六个参数的函数,即PMV=f(Ta,Tr,Va,φa,M,CLO)。当PMV=0时意味着室内热环境为最佳的热舒适状态。
在前述任一实施例中,利用双温差PID方式控制压缩机的工作频率和/或室内风机的转速具体包括如下步骤:确定当前温度值与设定温度值的温度差值与上一次所确定的第一温度差值的温度偏差值;根据所述温度偏差值,确定压缩机的工作频率F并相应地调整压缩机的工作频率;根据压缩机的工作频率F确定室内风机的转速R并相应地调整室内风机的转速。
具体的,根据所述温度偏差值,确定压缩机的工作频率F,按照如下公式(1)计算得到:
F=(T’_Ki×Dtn+T’_Kp×Ptn)×C;(1)
其中,Dtn=|Ptn–Ptn-1|,Ptn=|Tn–Tm|,T’_Ki为温度偏差系数,T’_Kp为温差系数,C为工作频率值系数,Dtn为所述温差偏差值,Ptn为所述温度差值,Tn为所述当前温度值,Tm为所述设定温度值。
在一些实施例中,压缩机的工作频率F设有上限和下限,以保证空调的运行效率,压缩机的使用寿命。当计算的工作频率F大于设定的上限值时,将压缩机的工作频率F设置为所述上限值;当计算的工作频率F小于设定的下限值时,将压缩机的工作频率F设置为所述下限值。
优选的,压缩机的工作频率F的范围为(36Hz,65Hz)。其中,上限值和下限值由不同的空调机型及压缩机机型在调试阶段进行大量实验统计确定。如:Dtn=2,Ptn=10,T’_Ki=4,T’_Kp=6,C=10,根据公式(1)得出F=(4×2+6×10)×10=68Hz。 计算的工作频率F大于上限值65Hz,将压缩机的工作频率F设置为所述上限值65Hz。
其中,根据压缩机的工作频率F确定室内风机的转速R,包括:压缩机的频率越高,室内风机的转速R越高。
一种可选的方式是,通过预设的压缩机的工作频率F与室内风机的转速R的对应关系,查表获得风机的转速,具体对应关系如表1所示:
表1
Figure PCTCN2017109298-appb-000001
当室内风机高速运行时,盘管温度高,显热比例高,除湿量少,当室内风机高速低速运行时候盘管温度低,潜热比例高,除湿量大。
压缩机不同的工作频率段对应的室内风机的转速不同,低频率段对应的室内风机的转速低,高频率段对应的室内风机的转速高,因为虽然在一定的频率下风速越低,除湿量越大,但是在高频率段风速过低会引起室内机盘管冻结的风险。
另一种可选的方式是,通过计算的方式,具体的,根据如下公式(2),由压缩机的工作频率F计算得出室内风机的转速R:
R=15×F+50。(2)
在一些实施例中,根据室内风机的转速R调整导风板的位置,包括:当室内风机的转速R大于设定转速值R’时,调整导风板处于最大出风位置;当室内风机的转速R小于或等于所述设定转速值R’时,调整导风板处于最小出风位置。室内风机的转速R大于设定转速值R’为高速,此时调整导风板处于最大出风位置,当室内风机的转速R小于或等于所述设定转速值R’为低速,调整导风板处于最小出风位置。如:R’为800r/min,当风速为850r/min时,调整导风板处于最大出风位置;当风速为750r/min时,调整导风板处于最小出风位置。
