本申请实施例提出的一种环境调节设备的控制方法,基于包括空调器和新风装置的环境调节设备,该方法在空调器的室内风道中可燃气体浓度大于预设浓度时,表明空调器有冷媒泄露的风险,此时采用新风装置将环境调节设备所在目标空间中的空气排出室外,避免目标空间的可燃气体浓度过高导致燃烧或爆炸等安全事故出现,从而提高空调器使用安全性。
进一步的,基于上述实施例,提出本申请环境调节设备的控制方法另一实施例。在一实施例中,所述新风装置设有室内风口、新风入口、与所述室内风道连通的新风出口、连通所述新风出口和所述新风入口的第一风道以及连通所述室内风口和所述新风出口的第二风道,所述新风装置还包括开关组件以及设于所述第二风道的新风风机,参照图5,所述当所述可燃气体浓度大于预设浓度时,控制所述新风装置运行以使所述室内空间的空气经过所述新风装置排出室外的步骤包括:
步骤S21,当所述可燃气体浓度大于预设浓度时,控制所述新风风机运行并控制所述开关组件以第一状态运行,以使所述新风出口关闭、所述目标空间的空气依次经过所述室内风口、所述第二风道、所述第一风道以及所述新风入口排出室外。
在一实施例中,所述第一风道与所述第二风道之间设有第一通风口和第二通风口,所述第一通风口对应所述新风出口设置,所述第二通风口对应所述新风入口设置,所述开关组件包括第一开关模块、第二开关模块以及第三开关模块。具体的,第二通风口和室内风口设于新风风机的进风侧,新风出口设于新风风机的出风侧。控制所述第一开关模块以第一子状态运行,控制所述第二开关模块以第二子状态运行以及控制所述第三开关模块以第三子状态运行;所述第一状态包括所述第一子状态、所述第二子状态以及所述第三子状态,所述第一子状态下关闭所述新风出口且打开所述第一通风口,所述第二子状态下块打开所述室内风口,所述第三子状态下关闭所述第二通风口。基于此,新风风机驱动空气依次经过室内风口、第二风道、第一通风口、第一风道以及新风入口后排出室外,具体路径如图2(a)。
开关组件除了第一开关模块、第二开关模块和第三开关模块以外,在其他实施例中,还可包括设于新风入口的第四开关模块。或者,其他实施例中,第一开关模块和第二开关模块也可合并为一个第四开关模块,第四开关模块可在室内风口与新风出口之间活动。开关组件以第一状态运行时,第四开关模块可活动至关闭新风出口的位置且与室内风口间隔设置。
在一实施例中,通过开关组件与新风风机的运行配合,从而实现新风风机的转向固定的基础上,可通过开关组件的状态控制实现新风装置可将室内包含可燃性冷媒的空气排出室外。其中,基于第一风道和第二风道的风道结构的基础上,进一步通过第一开关模块、第二开关模块和第三开关模块的配合,实现目标空间中具有燃爆风险的空气可快速排出室外。
在其他实施例中,当所述可燃气体浓度大于预设浓度时,也可控制新风风机运行并控制开关组件以第三状态运行,以使所述新风出口打开、所述室内风道的空气依次经过所述室内风口、所述第二风道、所述第一风道以及所述新风入口排出室外。
在其他实施例中,定义新风风机开启时气流流动方向上相对的两侧分别为第一侧和第二侧,室内风口和新风出口均可设置在第一侧,新风入口可设置在第二侧,当所述可燃气体浓度大于预设浓度时,可控制新风风机以第一转向运行,以驱动室内空气从室内风口进入到新风装置内并从新风入口排出室外。
进一步的,在一实施例中,所述控制所述开关组件以第一状态运行的步骤包括:
确定所述可燃气体浓度与所述预设浓度之间的浓度差值;
当所述浓度差值小于或等于预设浓度差时,执行所述控制所述新风风机运行并控制所述开关组件以第一状态运行,以使所述新风出口关闭、所述目标空间的空气依次经过所述室内风口、所述第二风道、所述第一风道以及所述新风入口排出室外的步骤;
当所述浓度差值大于所述预设浓度差时,控制所述新风风机运行并控制所述开关组件以第三状态运行,以使所述新风出口打开、所述目标空间内的空气依次经过所述室内风口、所述第二风道、所述第一风道以及所述新风入口排出室外、以及所述室内风道内的空气依次经过所述第二风道、所述第一风道以及所述新风入口排出室外。
预设浓度差具体为用于区分空调器冷媒泄露风险大小的临界值。
具体的,开关组件包括上述第一开关模块、第二开关模块以及第三开关模块时,第一开关模块可以第七子状态运行,第二开关模块以第五子状态运行以及第三开关模块以第六子状态运行,第三状态包括第七子状态、第五子状态以及第六子状态,其中,第七子状态下新风出口和第一通道口均打开。具体的,可根据浓度差值确定第一开关模块在第七子状态下的目标位置,浓度差值不同则目标位置不同,目标位置为第一位置与第二位置之间,第一位置为第一开关模块关闭新风出口时的位置,第二位置为第一开关模块关闭第一通风口时的位置。
浓度差值小于或等于预设浓度差值,表明泄露风险较小,出现燃爆等安全事故可能性较低,此时关闭新风出口,有利于加快目标空间中混杂有可燃性冷媒的空气排出室外的效率,并且可避免室内环境中空气排出室外造成室内热量损失,提高空调器运行安全性的同时保证室内舒适性;浓度差值大于预设浓度差值,表明泄露风险较大,出现燃爆等安全事故可能性较高,此时打开新风出口使室内风道内高浓度的可燃性冷媒以及目标空间内的可燃性冷媒可快速排出室外,从而进一步提高空调器的使用安全性。
进一步的,基于上述任一实施例,提出本申请环境调节设备的控制方法又一实施例。在一实施例中,参照图6,所述步骤S10之后,还包括:
步骤S30,当所述可燃气体浓度小于或等于所述预设浓度时,控制所述新风风机运行并控制所述开关组件以第二状态运行,以使室外新风依次经过所述新风入口、所述第一风道、所述第二风道以及所述新风出口送入所述室内空间。
在一实施例中,所述第一风道与所述第二风道之间设有第一通风口和第二通风口,所述第一通风口对应所述新风出口设置,所述第二通风口对应所述新风入口设置,所述开关组件包括第一开关模块、第二开关模块以及第三开关模块,控制所述第一开关模块以第四子状态运行,控制所述第二开关模块以第五子状态运行,控制所述第三开关模块以第六子状态运行;
其中,所述第二状态包括所述第四子状态、所述第五子状态以及所述第六子状态,所述第四子状态下打开所述新风出口且关闭所述第一通风口,所述第五子状态下关闭所述室内风口,所述第六子状态下打开所述第二通风口。基于此,新风风机驱动空气依次经过新风入口、第一风道、第二通风口、第二风道以及新风出口后送入室内,具体路径如图2(b)。
在其他实施例中,开关组件除了第一开关模块、第二开关模块和第三开关模块以外,还可包括设于新风入口的第四开关模块。或者,其他实施例中,第一开关模块和第二开关模块也可合并为一个第四开关模块,第四开关模块可在室内风口与新风出口之间活动。开关组件以第二状态运行时,第四开关模块可活动至关闭室内风口的位置且与新风出口间隔设置。
在其他实施例中,定义新风风机开启时气流流动方向上相对的两侧分别为第一侧和第二侧,室内风口和新风出口均可设置在第一侧,新风入口可设置在第二侧,当所述可燃气体浓度小于或等于预设浓度时,可控制新风风机以第二转向运行,以驱动室内空气从新风入口进入到新风装置内并从新风出口排出室外。
进一步的,基于上述任一实施例,提出本申请环境调节设备的控制方法再一实施例。在一实施例中,所述控制所述新风风机运行的步骤包括:控制所述新风风机以大于预设转速的转速运行。
在一实施例中,新风风机以最大转速运行,最大转速大于预设转速。在其他实施例中,新风风机也可以大于预设转速小于最大转速的转速运行。
具体的,预设转速可为最大转速的70%。
在一实施例中,新风风机以大于预设转速运行,也就是新风风机以高转速运行,有利于提高可燃性冷媒排出室外的效率。
具体的,在一实施例中,所述控制所述新风风机以大于预设转速的转速运行的步骤包括:确定所述可燃气体浓度与所述预设浓度之间的浓度差值;根据所述浓度差值在大于或等于所述预设转速的转速范围内确定目标转速;控制所述新风风机以所述目标转速运行。
其中,不同的浓度差值对应不同的目标转速。浓度差值与所述目标转速呈正相关。具体的,可预先建立浓度差值与目标转速之间的对应关系,对应关系可包括映射关系、计算公式等形式。基于该对应关系可在转速范围内确定当前浓度差值所对应的目标转速。例如,可根据浓度差值确定转速调整值,按照转速调整值调整预设转速获得目标转速。
进一步的,浓度差值与目标转速之间的对应关系可根据目标空间当前的气压值获取,不同的气压值可对应不同的对应关系。在一实施例中,可预先设置多于一个浓度差值与目标转速之间的对应关系,根据气压值在多于一个对应关系中确定目标对应关系,基于目标对应关系确定当前浓度差值所对应的目标转速。
在一实施例中,基于浓度差值确定新风风机的目标转速,有利于保证新风风机运行与可燃性冷媒的泄露风险精准匹配,保证空调器使用安全性的同时避免室内负压导致室外污染物进入室内。
进一步的,基于上述任一实施例,提出本申请环境调节设备的控制方法的再另一实施例,在一实施例中,控制所述新风装置运行以使所述环境调节设备所在的目标空间的空气经过所述新风装置排出室外的步骤之前,还包括:
当所述可燃气体浓度大于预设浓度时,控制所述空调器中的负载关闭;且/或,当所述可燃气体浓度大于预设浓度时,控制所述环境调节设备输出提示信息。
这里的负载可包括空调器的压缩机和/或室内风机等。
提示信息的形式可包括文字信息、图像信息、声音信息和/或灯光信息等。
在一实施例中,负载关闭有利于进一步避免空调器运行过程中出现燃爆事故,进一步提高空调器使用安全性。另外提示信息的输出,可提示用户检修空调器是否存在冷媒泄露情况,从而进一步提高空调器使用安全性。
此外,本申请实施例还提出一种存储介质,所述存储介质上存储有环境调节设备的控制程序,所述环境调节设备的控制程序被处理器执行时实现如上环境调节设备的控制方法任一实施例的相关步骤。
