本实施例根据上述方案,在空调处于制冷模式,且空调器的出风量小于预设出风量时,实时或定时检测空调器所在空间的室内湿度,再根据室内湿度调整压缩机的运行频率,从而使得压缩机能够根据外界的湿度进行运行频率的合理调整,避免空调器风量小时,出现凝露现象导致其制冷效果差的情况,保证了空调器在出风量较低时的制冷效果。
基于上述硬件构架,提出本申请空调器的控制方法的实施例。
参照图2,图2为本申请空调器的控制方法的第一实施例,所述空调器的控制方法包括以下步骤:
步骤S100,在空调器处于制冷模式,且所述空调器的出风量小于预设出风量时,实时或定时检测所述空调器所在空间的室内湿度;
在本申请中,空调器指的是具有变频压缩机的空调器,该空调器具有湿度传感器,空调器可根据湿度传感器检测空调器所在空间的湿度。
空调器在制冷时,其出风温度较低,一般为13℃至15℃,在当空调器的出风风量较低时(比如,空调器处于无风感模式或者柔风感模式,空调器的出风风量较低),因其出风风量小,会使得空调器所在空间的水蒸气与空调器送出的冷气充分接触,使得水蒸气吸收冷量,从而使得空调产生凝露;因凝露的产生吸收冷量放出热量,会使得室内温度下降的速度变慢,甚至会出现较热现象,导致空调器的制冷效果差,从而影响了用户的体验。基于上述情况,空调器会采集其运行参数(运行参数可以为出风量以及出风温度),从而根据其运行参数对空调器的压缩机的运行频率进行控制,以合理控制冷量的输出,避免冷量与室内的水蒸气充分接触。
在本实施例中,当空调器处于制冷模式中,且空调器的出风量小于预设出风量时,空调器实时或者定时检测其所处空间的湿度,也即检测室内湿度。
当然,本申请并不限定于空调器处于制冷模式且其出风量小于预设出风量时,检测室内湿度,也可在空调器的出风温度小于预设出风温度且其出风量小于预设出风量时,检测室内湿度。预设温度的设置依据为:空调器处于制冷模式下且空调器需要快速降低室内温度,也即预设温度可以为该依据下的任意合适的数值,比如13℃-15℃;预设出风量的设置依据为:空调器当前的出风量使得外界水蒸气能够与空调器输出的冷量凝结成水滴,预设出风量为该依据下的任意合数的数值。另外,空调器可以直接根据其当前所处的模式来判断运行参数是否满足预设条件,即空调器处于制冷模式且处于无风感模式,或者空调器处于制冷模式且处于柔风感模式(柔风感模式下的空调器出风量较小)。
步骤S200,根据所述室内湿度调整压缩机的运行频率,其中,所述室内湿度与所述运行频率成正比;
在本实施例中,室内湿度与压缩机的运行频率具有映射关系,空调器可以直接根据检测的湿度以及映射关系确定压缩机的运行频率调整值,使得压缩机按照运行频率运行,从而使得压缩机输出的冷量产生变化,使得冷量不足以外界的水蒸气(水蒸气的含量与湿度有关)凝结成水滴,也即使得空调器不会出现凝露现象,室内湿度与压缩机的运行频率是成正比的映射关系。
在室内湿度比较高时,则说明室内的水蒸气含量较多,空调器容易出现凝露现象;在当室内湿度较低时,则说明室内水蒸气含量较少,空调器不易出现凝露现象。针对上述情况,空调器在检测到室内湿度时,判断室内湿度是否处于预设湿度区间,若室内湿度处于预设湿度区间,则说明室内水蒸汽含量较多,需要控制压缩机的运行频率,也即空调器需要执行步骤S200;当然,若室内湿度不处于预设湿度区间时,则说明室内水蒸气含量较少,空调器不需要对压缩机进行运行频率的控制。
需要说明的是,空调器制冷使得室内湿度产生变化,在当检测的湿度小于预设湿度时,则当前室内水蒸气的含量较少,也即压缩机的运行频率不需要进行调整,也即空调器停止对压缩机进行运行频率的调整;另外,空调器可以计算当前见得湿度与上一次检测的湿度之间的湿度比值,在湿度比值小于预设阈值时,空调器停止对压缩机进行运行频率的调整,预设阈值表征当前室内湿度小于预设湿度。
本实施例提供的技术方案中,在空调处于制冷模式,且空调器的出风量小于预设出风量时,实时或定时检测空调器所在空间的室内湿度,再根据室内湿度调整压缩机的运行频率,从而使得压缩机能够根据外界的湿度进行运行频率的合理调整,避免空调器风量小时,出现凝露现象导致其制冷效果差的情况,保证了空调器在出风量较低时的制冷效果。
参照图3,图3为本申请空调器的控制方法的第二实施例,基于第一实施例,所述步骤S200包括:
步骤S210,根据所述室内湿度确定所述空调器所在空间的状态,其中,所述空调器所在空间的状态包括敞开状态以及封闭状态;
步骤S220,根据所述空间的状态确定所述压缩机的运行频率;
步骤S230,控制所述压缩机按照所述运行频率运行;
在本实施例中,空调器可以根据室内湿度确定空调器所在空间的状态,也即室内的状态。一般而言,室内的状态包括敞开状态以及封闭状态,敞开状态下的室内与室外有水蒸气的流动,使得室内的湿度变化较小,也即压缩机的运行频率调整幅度应该保持稳定;封闭状态下的室内与室外未进行水蒸气的流动,使得室内的湿度逐渐降低(空调器制冷时长越长,室内湿度越小),压缩机的运行频率的调整幅度也应该越来越小。基于此,空调器根据空间的状态设置压缩机运行频率与室内湿度的不同映射关系,然后,空调器可以室内湿度的变化速率来确定空间的当前状态,由此确定压缩机的运行频率,最后控制压缩机以确定的运行频率运行。
在本实施了提供的技术方案中,空调器根据室内湿度确定空调器所在空间的状态,再根据空间的状态确定压缩机的运行频率,由此控制压缩机按照确定的运行频率运行;使得空调器能够根据空间的状态采用对应的措施进行其压缩机运行频率的调整,提高了空调器的控制精度。
参照图4,图4为本申请空调器的控制方法的第三实施例,基于第二实施例,所述步骤210包括:
步骤S211,根据当前检测的室内湿度与上一次检测的室内湿度之间的湿度比值确定所述空间的状态,其中,在所述湿度比值处于第一比值区间时,判定所述空间为敞开状态,在所述湿度比值处于第二比值区间时,判定所述空间为封闭状态,所述第一比值区间大于所述第二比值区间;
在本实施例中,空调器可以根据室内湿度对空调器所在空间的状态进行判定,具体的,空调器计算当前检测的室内湿度以及上一次检测的室内湿度之间的湿度比值,空调器是实时或定时检测室内湿度,也即空调器内含有设定的室内湿度的检测间隔时长,湿度比值能够表征空间内的湿度的下降速率。空调器设置有2个比值区间,为第一比值区间以及第二比值区间,第一比值区间大于第二比值区间,第一比值区间可以为0.9-1,第二比值区间可以为0.65-0.8;在当空调器得到的湿度比值处于第一比值区间时,空调器判定室内湿度的下降速率较小,空调器认定空间的状态为敞开状态;在当空调器得到的湿度比值处于第二比值区间时,空调器判定室内湿度的下降速率较大,空调器认定空间的状态为封闭状态。
在本实施例提供的技术方案中,空调器根据当前检测的室内湿度以及上一次检测的室内湿度之间的湿度比值来确定空间的状态,从而使得空调器能够根据空间的实际情况调节压缩机的运行频率,提高了空调器的控制准确性。
参照图5,图5为本申请空调器的控制方法的第四实施例,基于第二实施例,所述步骤210包括:
步骤S212,获取室外湿度,并计算所述室外湿度与所述室内湿度的湿度差;
步骤S213,根据所述湿度差与预设湿度差确定所述空调器所在空间的状态,其中,在所述湿度差小于或等于预设湿度差时,判定所述空调器所在空间处于敞开状态,在所述湿度差大于预设湿度差时,判定所述空调器所在空间处于封闭状态;
在本实施例中,空调器根据室内湿度与室内湿度来判断空调器所在空间的状态,具体的,空调器可获取当前的室外湿度,室外湿度可由空调器联网获得,也可由空调器的外机的湿度传感器获得,本申请在此不作限定。在获得室外湿度时,空调器计算室内湿度与室外湿度的湿度差,若湿度差较小时(湿度差小于或等于预设湿度差,预设湿度差可以任意合适的数值,比如5%),则说明室外湿度与室内湿度相差不大,也即空间的状态为敞开状态;若湿度差较大时(湿度差大于预设湿度差),室内湿度与室外湿度的相差较大,此时,空调器判定空间的当前状态为封闭状态(处于封闭状态的空间,随着空调器的制冷运行时长增长,室内湿度逐渐较低)。
在本实施例提供的技术方案中,空调器计算室内湿度与室外湿度的湿度差,并根据湿度差来确定空间的状态,从而使得空调器能够根据空间的实际情况调节压缩机的运行频率,提高了空调器的控制准确性。
参照图6,图6为本申请空调器的控制方法的第五实施例,基于第二实施例,所述步骤210包括:
步骤S214,获取所述室内湿度的检测间隔时长,并计算当前检测的室内湿度以及上一次检测的室内湿度的室内湿度差;
步骤S215,根据所述检测间隔时长以及所述室内湿度差计算湿度变化率;
步骤S216,根据所述湿度差变化率确定所述空调器所在空间的状态,其中,在所述湿度变化率小于或等于预设阈值时,判定所述空间处于敞开状态,在所述湿度变化率大于预设阈值时,判定所述空间处于封闭状态;
在本实施例中,空调器根据室内湿度来判断空调器所在空间的状态,具体的,空调器计算当前检测室内湿度与上一次检测室内湿度的室内湿度差,然后获取室内湿度的检测间隔时长,从而根据检测间隔时长以及室内湿度差确定室内湿度变化速率。在当空间为敞开状态时,空间内的水蒸气与空间外的水蒸气进行流动,从而使得室内的湿度保持稳定,也即室内湿度变化速率较小;在当空间为封闭状态时,空间内的水蒸气与空间外的水蒸气不能进行流动,而随着空调器的制冷时长增长,空间内的水蒸气会逐渐减少,因此,空间在封闭状态时,室内湿度变化速率较大。基于此,空调器在获得室内湿度变化速率后,判断室内湿度变化速率是否小于或等于预设阈值,若小于或等于,则判定空间处于敞开状态;若大于,则判定空间处于封闭状态。
在本实施例提供的技术方案中,空调器计算当前检测的室内湿度与上一次检测的室内湿度的室内湿度差,由此获得室内湿度变化速率,再根据室内湿度变化速率来确定空间的状态,从而使得空调器能够根据空间的实际情况调节压缩机的运行频率,提高了空调器的控制准确性。
参照图7,图7为本申请空调器的控制方法的第六实施例,基于第二至第五实施例,所述步骤S220包括:
步骤S221,在所述空调器所在的空间的状态为敞开状态时,获取所述压缩机的运行频率与所述压缩机的运行时长的映射关系;
步骤S222,根据所述映射关系以及所述运行时长确定所述运行频率;
在本实施例中,空调器基于敞开状态的空间采用对应的映射关系来确定压缩机的运行频率,具体的,空调器对压缩机的运行频率与压缩机的运行时长设置映射关系,且映射关系下的运行频率与运行时长成反比,也即压缩机的运行时长越长,运行频率越小,也即室内的水蒸气含量较高,需要一直降低压缩机的运行频率,以避免空调器产生凝露现象。空调器再根据映射关系以及压缩机的运行时长得到运行频率,从而使得压缩机按照该运行频率运行。
本实施例提供的技术方案中,空调器在确定空间的状态为敞开状态时,获取压缩机运行频率与其运行时长的映射关系,由此根据映射关系确定对应的运行频率,使得压缩机根据运行频率运行,从而使得压缩机的运行频率的调整更为合理,保证了空调器的制冷效果。
参照图8,图8为本申请空调器的控制方法的第七实施例,基于第二至第五实施例,所述步骤S220包括:
步骤S223,在所述空调器所在的空间的状态为封闭状态时,确定所述室内湿度对应的凝露临界频率;
步骤S224,计算当前检测的室内湿度与上一次检测的室内湿度之间的比值;
步骤S225,根据当前计算的湿度比值与上一次计算的湿度比值计算湿度比值变化速率;
步骤S226,根据所述凝露临界频率以及所述湿度比值变化速率确定所述运行频率;
在本实施例中,空调器基于敞开状态的空间采用对应的映射关系来确定压缩机的运行频率,具体的,空调器对压缩机的运行频率(运行频率调整值)与预设运行频率设置映射关系,且映射关系下的运行频率与压缩机的凝露临街频率成正比;需要说明的是,凝露临街频率为当前湿度下对应的凝露测试合格的运行频率,也即压缩机处于该凝露临街频率运行时,空调器输出的冷量不会与该湿度对应的水蒸气凝结成滴,湿度对应的凝露临街频率为经验值。
映射关系可以为:
Fr=K*f0,其中,Fr为运行频率调整值,K为系数,f0为当前湿度对应的预设运行频率。
需要说明的是K(K可为1.1-1.5)是变化的,而K的变化取决于湿度比值的下降速率,在湿度比值的下降速率越快K值大,也即在当前获得湿度比值与上一次获得的湿度比值之间的湿度比值速率越大时,K值越大;基于此,空调器在获得当前的室内湿度时,根据室内湿度确定凝露临界频率,然后计算湿度比值与上一次计算的湿度比值计算湿度比值变化速率(空调器每次检测室内湿度时,会根据当前检测室内湿度以及上一次检测室内湿度计算湿度比值,并存储湿度比值,从而使得空调器具有当前计算的湿度比值以及上一次计算的湿度比值),空调器再根据湿度比值变化速率确定K值,最后空调器根据K值以及凝露临界频率确定压缩机的运行频率。
本实施例提供的技术方案中,空调器在确定空间的状态为封闭状态时,根据室内湿度计算湿度比值变化速率,并获取当前室内湿度对应的凝露临界频率,再根据凝露临界频率以及湿度比值变化速率确定压缩机的运行频率,使得压缩机根据确定的运行频率运行,从而使得压缩机的运行频率的调整更为合理,保证了空调器的制冷效果。
