Description

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。
空调的制冷量分为显热和潜热两部分,显热主要影响室内温度,潜热主要影响室内湿度,因此显热和潜热均会影响人的舒适度。如何控制室内的温度和湿度从而能够让用户有更好的体验,是目前广泛受到关注的问题。
现有技术公开一种空调用分时温湿分控方法,该方法包括:判断室内湿度是否高于空调的设定湿度;若高于空调的设定湿度,则驱动空调进行除湿;若没高于空调的设定湿度,则驱动空调进行制冷;所述若高于空调的设定湿度,则驱动空调执行除湿,具体为:若高于空调的设定湿度,则判断室内温度是否高于空调的设定温度;若没高于空调的设定温度,则驱动空调单独进行除湿;若高于空调的设定温度,则判断室内温度是否比空调的设定温度高t1度;其中,1.5≤t1≤3;若是,则提高空调的压缩机的频率;若否,则先降低空调的风机转速后提高空调的压缩机的频率。该现有技术虽然披露了可以通过分时温湿分控方法保持室内的温度和湿度,但是该方法仅仅披露了当高于空调的设定温度时,提高空调的压缩机的频率;若否,则先降低空调的风机转速后提高空调的压缩机的频率。本领域技术人员根据该现有技术的披露,无法想到更加具体详细的压缩机频率调整的方案以及风机转速调整的方案。
现有技术公开的另一种用于控制温度和湿度的方法,该方法披露了如下内容:b.计算空调在制冷模式下的运行时间,当运行时间达到预设阈值时,根据以下条件判定当前是否需要对压缩机的工作频率进行限频,是否需要对室内风机转速进行调整:b1.如果当前室内温度与预设温度的差值≥2℃,则对压缩机的工作频率不进行限频,对室内风机的当前转速不作调整;b2.如果1℃≤当前室内温度与预设温度的差值<2℃,则对压缩机的工作频率不进行限频,但是将室内风机转速降低至比当前室内风机转速低一个档位,且最低为低档位运行;b3.如果当前室内温度与预设温度的差值<1℃,
且当前室内相对湿度≥70%,则对压缩机的工作频率不进行限频,但是将室内风机转速降低至比当前室内风机转速最多低两个档位,且最低为低速档位运行;b4.如果当前室内温度与预设温度的差值<1℃,且当前室内相对湿度<70%,则对压缩机的工作频率进行限频,同时将室内风机转速降低至比当前室内风机转速最多低两个档位,且最低为低速档位运行。该现有技术虽然披露了相对具体的压缩机频率调整方案以及风机转速调整方案,即在一定条件下对工作频率进行限频或对风速进行档位调节,但是限频仅是限定压缩机的工作频率为固定值,且风速仅简单分为四档。可以看出,该方案对压缩机的工作频率和风速的调整过程并不精细。

空调的制冷量分为显热和潜热两部分,显热主要影响室内温度,潜热主要影响室内湿度,因此显热和潜热均会影响人的舒适度。当房间温差大的时候,我们希望房间温度尽快降低,此时空调的显热占比越大越好。当房间温度接近或者达到设定温度后,如果湿度大,需要除湿的时候,此时需要空调的潜热占比越大越好。在本实施例中,通过控制室内风机的转速和压缩机的工作频率可以有效的控制潜热/显热比,来达到除湿和降温的效果。并且通过合理的控制潜热/显热比,能够做到温湿双控,将室内湿度和室内温度控制在设定的目标范围。
图1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1所示,包括:

空调一般装设于客厅、卧室和会议室等室内空间中,因此,步骤S101中所获取的即是空调所安装的客厅、卧室或者会议室等室内空间的当前温度值,也即是本次流程中所获取的实时的室内温度t。
空调设置有第一温度传感器,用于检测室内环境的当前温度值。第一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,从而提高本文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。

图2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2所示,包括:
步骤S201,在空调制冷模式下,采集室内温度t和室内湿度RH。
在本实施例中,空调设置有第一温度传感器,用于检测室内环境的当前温度值。第三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,从而提高本文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,从而提高本文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。
步骤S202,根据所述室内温度t和室内湿度RH判断是否满足条件,如果是,则根据所述室内湿度RH控制压缩机的工作频率F,并根据压缩机的工作频率F调整室内风机的转速R,以使室内湿度和室内温度均位于设定的目标范围内。
空调***针对室内温度t和室内湿度RH预设有判断条件,根据步骤S201采集的室内温度t和室内湿度RH判断是否满足条件,如果满足,则根据所述室内湿度RH控制压缩机的工作频率F,并根据压缩机的工作频率F调整室内风机的转速R,以使室内湿度和室内温度均位于设定的目标范围内。基于多个参数对压缩机的工作频率F进行调节,提高了调整的精确度。
在本实施例中,提供了一种精细化的控制空调压缩机的频率和空调的风机转速的方法,在制冷模式下,采集实时的室内温度与室内湿度,判断是否需要对空调的运行状态进行调节,综合室内湿度对压缩机的工作频率进行调节,进而调整室内风机的转速,以使室内湿度和室内温度均位于设定的目标范围内,能够有效的控制潜热/显热比,提高温湿双控的效果,同时提高了用户体验。
在一些实施例中,在步骤S202中,根据所述室内温度t和室内湿度RH判断是否满足条件,如果是,则根据室内盘管的温度Tpn和所述室内湿度RH控制压缩机的工作频率F,并根据压缩机的工作频率F调整室内风机的转速R,以使室内湿度和室内温度均位于设定的目标范围内。
在前述任一实施例中,室内目标温度对应有目标湿度范围(RH1,RH2),这里,可在空调***中预先保存室内目标温度值与目标湿度范围(RH1,RH2)的对应关系,即针对每个室内目标温度,可对多个人体进行测试,获取对应的人体感觉最舒适的湿度,获取在室内目标温度的设定区域内,多个人体采集样本的与设定体感舒适等级对应的湿度值,并根据多个湿度值,确定与室内目标温度对应的目标湿度范围(RH1,RH2),并保存对应关系。例如:室内目标温度是25℃,此时,湿度在相对湿度40%~60%之间,大部分用户会感觉最舒服,因此,可将湿度40%~60%确定与设定温25℃所对应的目标湿度范围,并保存室内目标温度25°与目标湿度范围40%~60%之间的对应关系。
从而,空调***中预先保存的室内目标温度与目标湿度范围的对应关系可如表1所示:
表1
室内目标温度 | 目标湿度范围 |
30℃ | 湿度30%~50% |
28℃ | 湿度30%~60% |
… | … |
25℃ | 湿度40%~60% |
… | … |
根据表1所示对应关系,确定与空调当前室内目标温度对应的当前目标湿度范围(RH1,RH2)。如表1所示,当前设定的温度为28°,则获取的当前目标湿度范围为30%~60%。
室内温度在空调运行过程中会不断变化,为满用户需求需要将室内温度控制在一定范围内。室内温度目标范围取决于用户设定的室内目标温度,根据用户设定的室内目标温度和***预设的温度波动值确定。其中,室内目标温度由用户通过空调遥控器,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设置。例如:***预设的温度波动值为2℃,用户设定的室内目标温度为28℃,则室内温度目标范围为(26℃,30℃)。
在一些实施例中,根据室内盘管的温度Tpn与室内盘管的目标温度Tpm的温差PT,和,室内盘管的温度变化DT计算并调整压缩机的工作频率F。具体的,根据如下公式(1)确定压缩机的工作频率F:
F=T_Ki×DT+T_Kp×PT; (1)
其中,PT=Tpn–Tpm,DT=Tpn–Tpn1;Tpn1为前一次采集的室内盘管温度;T_Kp、T_Ki分别为加权系数。
其中,T_Ki的选取与***配置和外界环境温度相关,T_Kp的选取与***配置和外界环境温度相关。如:外界环境温度越高,T_Ki或T_Kp的取值越高。外界环境温度高,为达到目标温度或湿度对各项参数需要调节的幅度越大,因此加权系数越大。
外界环境温度包括室内环境温度或室外环境温度。在***配置中,T_Ki和T_Kp的选取与节流装置为毛细管或膨胀阀,压缩机的排量性能或冷凝器和蒸发器的大小相关。
其中,T_Ki的取值范围为1~10,T_Kp的取值范围为1~8。优选地,T_Ki=3、4、5、6或7;T_Kp=3、4、5、6或7。例如:当T_Ki=4,T_Kp=5,PT=10,DT=2时,根据公式(1):F=4×2+5×10=58,单位为Hz。
在一些实施例中,根据室内湿度RH与目标湿度RH_Target的湿度差ΔRH,和,室内湿度的变化ΔRH’计算并调整压缩机的工作频率F。具体的,根据如下公式(2)确定压缩机的工作频率F:
F=RH_Ki×ΔRH’+RH_Kp×ΔRH; (2)
其中,ΔRH=RH–RH_Target,ΔRH’=RH-RH1;RH1为前一次采集的室内湿度,RH_Ki、RH_Kp分别为设定的加权系数。
其中,RH_Ki的选取与***配置和外界环境温度相关,RH_Kp的选取与***配置和外界环境温度相关。如:外界环境温度越高,RH_Ki或RH_Kp的取值越大。外界环境温度高,为达到目标温度或湿度对各项参数需要调节的幅度越大,因此加权系数越大。外界环境温度包括室内环境温度或室外环境温度。在***配置中,RH_Ki和RH_Kp的选取与节流装置为毛细管或膨胀阀,压缩机的排量性能或冷凝器和蒸发器的大小相关。
其中,RH_Ki的取值范围为1~10,RH_Kp的取值范围为1~8。优选地,RH_Ki=2、3、4、5、6或7;RH_Kp=2、3、4、5、6或7。优选地,目标湿度RH_Target的优选值为52%。例如:当RH_Ki=2,RH_Kp=4,ΔRH=15,ΔRH’=4时,根据公式(1):F=2×4+4×15=68,单位为Hz。
在一些实施例中,首先,根据室内盘管的温度Tpn由公式(1)计算压缩机的第一候选工作频率;其次,根据室内湿度RH由公式(2)计算压缩机的第二候选工作频率;最后,取所述第一候选工作频率和第二候选工作频率中的值小者作为压缩机的工作频率F。综合不同参数对压缩机的工作频率进行计算,进一步提高了空调调节的精准度。
在一些实施例中,空调***设置有压缩机的工作频率范围。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。以保证空调的运行效率,延长空调压缩机的使用寿命。优选地,压缩机的工作频率范围为(30Hz,70Hz)。如:当预设的压缩机的工作频率范围为(30Hz,70Hz),若根据公式(1)或(2)得出的压缩机的工作频率F为25Hz时,则调整压缩机的工作频率为设定的下限值30Hz;若根据公式(1)或(2)得出的压缩机的工作频率F为75Hz时,则调整压缩机的工作频率为设定的上限值70Hz。
在前述任一实施例中,在确定压缩机的工作频率F之后,根据压缩机的工作频率
F调整室内风机的转速R,包括:压缩机的频率越高,室内风机的转速R越高。
具体的调节方式如下: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2所示:
表2
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(3),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。 (3)
