具体实施方式
应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
本发明提供一种空调器制冷控制方法。
参照图1,图1为本发明空调器制冷控制方法第一实施例的流程示意图。
本实施例提出一种空调器制冷控制方法,该空调器制冷控制方法包括:
步骤S10,在空调器进入制冷模式后,定时获取室内环境温度与设定温度之间的温度差;
本实施例所述的空调器进入制冷模式,可指空调器开机后直接以制冷模式运行,也可为空调器由其它模式切换至制冷模式,例如空调器由除湿模式进入制冷模式。室内环境温度可通过检测空调器室内机的回风温度得到,例如在空调器室内机的回风口处设置温度传感器检测;或者,该室内环境温度也可由其它装置上设置的温度传感器检测得到,例如用户佩戴的可穿戴设备(例如手环)上的温度传感器检测得到,该可穿戴设备检测得到的温度为用户周围温度,更加准确。定时获取室内环境温度以及设定温度的周期可由开发人员根据需要进行设定。
步骤S20,在所述温度差大于第一预设温度差,且所述空调器制冷运行的持续时长大于预设时长时,提高所述空调器的运行频率;
该第一预设温度差以及预设时长可由开发人员根据需要进行设定,例如该第一预设温度差可为5℃,预设时长可为3min。提高空调器的运行频率可通过多种方式,例如可直接将空调器的运行频率提高至预设频率,该预设频率可为目标运行频率,也可为将运行频率分为多个级别将运行频率直接提高至最高级别的运行频率;或者,也可在当前运行频率的基础上增加预设频率增量,以提高运行频率;或者直接提高目标频率,可通过多种方式实现,在此不再赘述。
步骤S30,控制所述空调器按照提高后的所述运行频率运行,以使所述空调器快速制冷模式。
空调器进入快速制冷模式之后,压缩机运行频率较大,为避免压缩机异常或者空调器的温度降至设定温度之下,则需要在快速制冷模式下检测是否需要退出快速制冷模式,退出快速制冷模式的条件可由开发人员根据需要进行设定。
本实施例提出的空调器制冷控制方法,在空调器进入制冷模式后,定时获取室内环境温度与设定温度之间的温度差,并在所述温度差大于第一预设温度差,且所述空调器制冷运行的持续时长大于预设时长时,提高所述空调器的运行频率,控制所述空调器按照提高后的所述运行频率运行,以减少空调器达到设定温度的时长。
进一步地,参照图2,基于第一实施例提出本发明空调器制冷控制方法第二实施例,在本实施例中,所述步骤S20包括:
步骤S21,在所述温度差大于第一预设温度差,且所述空调器制冷运行的持续时长大于预设时长时,对所述空调器本次运行的目标频率值增加预设频率增量;
步骤S22,将增加预设频率增量的目标频率值作为所述空调器的运行频率。
本实施例公开的技术方案中,提高空调器的运行频率时可直接对所述空调器本次运行的目标频率值增加预设频率增量,将增加预设频率增量的目标频率值作为所述空调器的运行频率,使得空调器的运行频率调整的较高的频率,且不会出现温度跳变过快引起用户不适。其它提高空调器运行频率的方式已经在第一实施例中举例说明,在此不再赘述。
可以理解的是,该预设频率增量可为一个固定值,即在目标频率的基础上直接增加该固定值,或者该预设频率增量可由其它参数确定,以下通过具体方案对预设频率增量的确定进行说明:
1)对所述空调器本次运行的目标频率值增加预设频率增量的步骤包括:
确定当前室外温度所在区间对应的预设频率增量;
对所述空调器本次运行的目标频率值增加当前室外温度所在区间对应的所述预设频率增量。
由于室外环境温度越高,在制冷时越难达到设定温度,则需要根据室外温度确定对应的预设频率增量,室外环境温度越高则对应的预设频率增量越大。
2)对所述空调器本次运行的目标频率值增加预设频率增量的步骤包括:
确定室内环境温度与设定温度之间的温度差所在区间对应的预设频率增量;
对所述空调器本次运行的目标频率值增加当前室外温度所在区间对应的所述预设频率增量。
室内环境温度与设定温度之间的温度差越大,则空调器在制冷时达到设定温度所需要的时间越长,则温度差越大对应的预设频率增量越大。
3)对所述空调器本次运行的目标频率值增加预设频率增量的步骤包括:
确定室内环境温度所在区间对应的预设频率增量;
对所述空调器本次运行的目标频率值增加当前室外温度所在区间对应的所述预设频率增量。
室内环境温度越高则需要更多的冷量来降温,则室内环境温度越高对应的预设频率增量越大。
以上三种实施例仅仅为确定预设频率增量的具体实施方式的举例说明,并不限定于上述几种方式,其它确定预设频率增量的的方式均在本发明的保护范围内。
进一步地,参照图3,基于第一或第二实施例提出本发明空调器制冷控制方法第三实施例,在本实施例中,所述步骤S30之后,本发明空调器制冷控制方法还包括步骤:
步骤S40,定时获取室内环境温度与设定温度之间的温度差;
步骤S50,在当前获取到的温度差小于上一周期获取到的温度差,且当前获取到的温度差与上一周期获取到的温度差之间的差值大于预设阈值时,降低所述空调器的当前运行频率。
在室内环境温度的温差变化过大时,可能此时的运行频率过大,会导致用户不适,则可在当前获取到的温度差与上一周期获取到的温度差之间的差值大于预设阈值时,降低所述空调器的当前运行频率,以避免运行频率过大,实现运行频率的灵活调节。
可以理解的是,降低所述空调器的当前运行频率,可通过预设的运行频率降低量来实现,该运行频率降低量可通过当前获取到的温度差与上一周期获取到的温度差之间的差值来确定,差值越大运行频率降低量越大。
进一步地,基于上述任一实施例提出本发明空调器制冷控制方法第四实施例,在本实施例中,执行步骤S20的同时执行步骤:
提高所述空调器的室内风机转速;
执行步骤S30的同时,执行步骤:

本实施例中,在所述温度差大于第一预设温度差,且所述空调器制冷运行的持续时长大于预设时长时,提高所述空调器的运行频率的同时提高空调器的室内风机转速,使得空调器的制冷效率进一步提高,以使室内温度快速达到设定温度,进一步降低空调器进入制冷模式时达到设定温度的时长。
可以理解的是,该预设风速增量可为一个固定值,即在目标频率的基础上直接增加该固定值,或者该预设风速增量可由其它参数确定,以下通过具体方案对预设风速增量的确定进行说明:
1)所述提高所述空调器的室内风机转速的步骤包括:
确定当前室外温度所在区间对应的预设风速增量;
对所述空调器当前室内风机转速增加当前室外温度所在区间对应的所述预设风速增量。
由于室外环境温度越高,在制冷时越难达到设定温度,则需要根据室外温度确定对应的预设风速增量,室外环境温度越高则对应的预设风速增量越大。
2)所述提高所述空调器的室内风机转速的步骤包括:
确定室内环境温度与设定温度之间的温度差所在区间对应的预设风速增量;
对所述空调器当前室内风机转速增加当前室外温度所在区间对应的所述预设风速增量。

3)所述提高所述空调器的室内风机转速的步骤包括:
确定室内环境温度所在区间对应的预设风速增量;
对所述空调器当前室内风机转速增加当前室外温度所在区间对应的所述预设风速增量。
室内环境温度越高则需要更多的冷量来降温,则室内环境温度越高对应的预设风速增量越大。
以上三种实施例仅仅为确定预设风速增量的具体实施方式的举例说明,并不限定于上述几种方式,其它确定预设风速增量的的方式均在本发明的保护范围内。
进一步地,基于第一至第四任一实施例提出本发明空调器制冷控制方法第五实施例,在本实施例中,所述空调器制冷控制方法还包括步骤:在所述空调器的运行状态满足以下任一条件时,控制所述空调器退出快速制冷模式:

本实施例公开的方案中,可定时获取室内环境温度并根据获取到的室内环境温度与设定温度计算温度差,在定时获取室内环境温度的同时获取室内换热器中部温度、压缩机排气温度、室外换热器出口温度等其它温度参数,室内环境初始温度为进入制冷模式之后第一次获取到的室内环境温度,室外换热器出口的初始温度为进入制冷模式之后第一次获取到的室外换热器出口温度。
通过设定退出快速制冷的条件,避免压缩机异常或者空调器的温度降至设定温度之下,以保证空调器正常运行,同时提高用户舒适性。
本发明保护的空调器制冷控制方法可运行于空调器的控制芯片中,该空调器还包括存储器,该存储器可承载于控制芯片中也可为空调器的其它存储介质如闪存,在空调器启动后该空调器制冷控制方法对应的空调器制冷控制程序加载至控制芯片的内存中运行。
