相关申请的交叉引用
本申请基于申请号为201810603391.4,申请日为2018年06月12申请的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及空调技术领域,特别涉及一种空调的控制方法、装置及具有其的空调。
背景技术
目前,空调器有时会在室内温度高、室外低温(如-25℃~0℃或温度更低)的工况下运行,例如通讯基站、高级餐厅、面包房、酒店、舞厅等场所,室内有大量热源使得室内温度高,而这些场所对室内空气的品质有特殊要求,不能将室外低温空气直接引入室内以降低室内的温度,需要空调器在室内制冷。常规空调器仅能在室外温度在7℃~43℃的范围内制冷,无法在室外温度为-25℃~0℃或温度更低时制冷。
同样作为蒸发器,室外侧与室内侧的温度存在巨大差异,室外温度决定了低压会处于较低的状态。在保证舒适的制冷送风温度的情况下,由于低压较低,制冷内机所需的冷媒量会较正常温度制冷时少,即制冷内机换热后冷媒的过热度大,而外机基本没有过热。所以,单位冷媒流量状态下,外机的阻力更小,冷媒更容易流向外机。当外机电子膨胀阀开启较大时,流向制冷内机的冷媒较少,容易出现制冷内机之间偏流的情况。而外机电子膨胀阀开启较小时,流向制冷内机的冷媒较多,且处于低压较低的情况,容易出现内机结霜的情况。制冷内机所需过热度较大,目前恒定过热度的控制方法很难适应这样的应用场景。
相关技术中,判断制冷内机冷媒的充足与否,最直观的方法是通过送风温度与回风温度温差,及设定温度的判断来实现。加出风温度传感器往往被认为可能判断不准确(温度分布不均问题)或增加产品成本。因此,目前在常温工况下,制冷内机的送风温度范围往往可以通过换热器中部的温度进行判断。但是在低温混合模式下,由于系统低压较低,使用换热器中部温度的判断方法会失效,有待解决。

具体实施方式
下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本申请,而不能理解为对本申请的限制。
下面参照附图描述根据本申请实施例提出的空调的控制方法、装置及具有其的空调,首先将参照附图描述根据本申请实施例提出的空调的控制方法。
图1是本申请实施例的空调的控制方法的流程图。
本申请实施例提供的空调,需要在低温混合模式下运行,低温混合模式为低温制冷的情况下,由于室外温度较低,因此室内也会同时有制热需求,所以,低温制冷往往会伴随着制热,即系统在这种情况往往处于同时制热制冷的运行状态当中。
如图1所示,该空调的控制方法包括以下步骤:
S1,确定空调的室外换热器处于蒸发器状态运行。
在低温混合模式下,根据室内制冷制热的负荷情况,空调的室外换热器会进行冷凝器和蒸发器之间的切换。室外温度低情况下,制热负荷往往比制冷负荷大,使得室外换热器大多会处于蒸发器状态。因此,在调节外机电子膨胀阀的开度之前,需要确定空调的室外换热器处于蒸发器状态运行。
S2,获取制冷内机的冷媒的状态信号。
具体地,可以根据制冷内机的冷媒的容量判断制冷内机的冷媒的状态信号,其中,冷媒的状态信号包括冷媒不足的状态信号和冷媒过剩的状态信号。
S3,根据制冷内机的状态信号,调节外机电子膨胀阀的开度。
具体地,当系统进入低温混合模式且室外换热器为蒸发器状态运行时,可以通过判断制冷内机的冷媒不足状态信号与制冷内机的冷媒过剩状态信号对外机电子膨胀阀的开度进行调节。
由此,根据本申请实施例的空调的控制方法通过,确定空调的室外换热器处于蒸发器状态运行,并获取制冷内机的冷媒的状态信号,以根据制冷内机的状态信号,调节外机电子膨胀阀的开度,即根据制冷内机中冷媒的充足程度,动态地调整电子膨胀阀的开度,使得制冷内机中冷媒的量与电子膨胀阀的开度自适应,有效提高控制的可靠性,有效降低制冷内机的成本,有效节约资源,且简单易实现。
在本申请的一个实施例中,如图2所示,上述的空调的控制方法,根据制冷内机的状 态信号,调节外机电子膨胀阀的开度,具体包括以下步骤:
S201,获取发出冷媒不足的第一状态信号的制冷内机在所有制冷内机中的第一比重。
具体地,当系统进入低温混合模式且室外换热器为蒸发器状态运行时,可以通过判断制冷内机的冷媒不足状态信号与制冷内机的冷媒过剩状态信号对外机电子膨胀阀的开度进行调节。因此,可以先获取发出冷媒不足的第一状态信号(冷媒不足信号为ON)的制冷内机在所有制冷内机中的第一比重,例如,第一比重可以为X%。
S202,检测并确认第一比重超出预设的第一比重阈值的第一持续时长超出预设的第一时长。
具体地,当发出冷媒不足的第一状态信号的制冷内机在所有制冷内机中的第一比重X%超出预设的第一比重阈值时,再次判断第一比重超出预设的第一比重阈值的第一持续时长是否超出预设的第一时长,例如,第一预设时长为β分钟。
如果判断出第一比重超出预设的第一比重阈值的第一持续时长超出预设的第一时长,执行步骤S203。其中,预设的第一比重阈值和预设的第一时长可以由本领域技术人员根据实际情况进行设计,在此不做具体限定。
S203,且检测并确认所有制冷内机均发出冷媒过剩的第二状态信号的第二持续时长超出预设的第二时长。
具体地,当所有制冷内机均发出冷媒过剩的第二状态信号(冷媒过剩信号为OFF)时,判断所有发出冷媒过剩的第二状态信号的第二持续时长是否超出预设的第二时长。
如果判断出所有制冷内机均发出冷媒过剩的第二状态信号的第二持续时长超出预设的第二时长,执行步骤S204。
其中,预设的第二时长可以由本领域技术人员根据实际情况进行设计,在此不做具体限定。
S204,则控制减小外机电子膨胀阀的开度。
具体地,当满足第一比重超出预设的第一比重阈值的第一持续时长超出预设的第一时长,且所有发出冷媒过剩的第二状态信号的第二持续时长超出预设的第二时长时,可以控制减小外机电子膨胀阀的开度,例如,外机电子膨胀阀关ωPls,从而有效避免在各种工况下,制冷内机由于外机电子膨胀阀开度太大导致室内机冷媒较少导致的冷媒偏流问题。
在本申请的一个实施例中,如图3所示,上述的空调的控制方法,还包括以下步骤:
S301,检测并确认第一比重超出预设的第一比重阈值的第一持续时长超出第一时长,和第二持续时长超出第二时长未同时满足,获取发出冷媒过剩的第三状态信号的制冷内机在所有制冷内机中的第二比重。
具体地,如果不能同时满足第一比重超出预设的第一比重阈值的第一持续时长超出预 设的第一时长,且所有发出冷媒过剩的第二状态信号的第二持续时长超出预设的第二时长,则可以获取发出冷媒过剩的第三状态信号(冷媒过剩为ON)的制冷内机在所有制冷内机中的第二比重,例如,第二比重可以为Y%。
S302,检测并确认第二比重超出预设的第二比重阈值的第三持续时长超出预设的第三时长。
其次,当发出冷媒过剩的第三状态信号的制冷内机在所有制冷内机中的第二比重Y%超出预设的第二比重阈值时,再次判断第二比重超出预设的第二比重阈值的第三持续时长是否超出预设的第三时长,例如,第三预设时长为β分钟。
如果判断出第二比重超出预设的第二比重阈值的第三持续时长超出预设的第三时长,则继续执行步骤S303;否则执行步骤S306。
其中,预设的第三比重阈值和预设的第三时长可以由本领域技术人员根据实际情况进行设计,在此不做具体限定。
S303,检测并确认所有制冷内机均发出冷媒不足的第四状态信号的第四持续时长超出预设的第四时长。
具体地,当所有制冷内机均发出冷媒不足的第四状态信号(冷媒不足信号为OFF)时,进一步判断所有发出冷媒不足的第四状态信号的第四持续时长是否超出预设的第四时长。
如果判断出所有制冷内机均发出冷媒不足的第四状态信号的第四持续时长超出预设的第四时长,则继续执行步骤S304;否则执行步骤S306。
其中,预设的第四时长可以由本领域技术人员根据实际情况进行设计,在此不做具体限定。
S304,检测并确认空调的排气过热度大于预设的过热度阈值。
进一步地,还需要获取空调的排气过热度,然后将排气过热度与预设的过热度阈值进行比较。如果判断出空调的排气过热度大于预设的过热度阈值,则继续执行步骤S305;否则执行步骤S306。
其中,预设的过热度阈值可以为θ℃,其可以由本领域技术人员根据实际情况进行设计,在此不做具体限定。
S305,控制增大外机电子膨胀阀的开度。
具体地,当满足第二比重超出预设的第二比重阈值的第三持续时长超出预设的第三时长,且所有发出冷媒不足的第四状态信号的第四持续时长超出预设的第四时长时,且空调的排气过热度大于θ℃,则可以控制增大外机电子膨胀阀的开度,例如,外机电子膨胀阀的开ωPls,从而有效避免在各种工况下,制冷内机由于外机电子膨胀阀开度太小导致室内机冷媒过多,送风温度过低的问题。
在本申请的一个实施例中,上述的空调的控制方法,还包括:检测并确认第二比重超出第二比重阈值的第三持续时长超出第三时长,以及第四持续时长超出第四时长,以及排气过热度大于过热度阈值未同时满足时,控制维持外机电子膨胀阀的当前开度。
具体而言,如果不能同时满足第二比重超出预设的第二比重阈值的第三持续时长超出预设的第三时长,所有发出冷媒不足的第四状态信号的第四持续时长超出预设的第四时长时,以及空调的排气过热度大于θ℃,则控制维持外机电子膨胀阀的当前开度,即保持外机电子膨胀阀开度不变。
在本申请的一个实施例中,获取制冷内机的冷媒的状态信号,包括:获取用于识别冷媒状态的状态参数,根据状态参数,控制制冷内机发送状态信号;其中,状态参数中至少包括空调的送风温度。
具体而言,冷媒状态的状态参数包括:制冷内机的内机电子膨胀阀的开度;空调的回风温度、空调的送风温度以及空调的回风温度与空调的送风温度之间的第一温差;以及空调的回风温度与设定的制冷温度之间的第二温差。
其中,状态信号包括冷媒不足的状态信号和冷媒过剩的状态信号,冷媒不足的状态信号包括冷媒不足的第一状态信号和冷媒不足的第四状态信号;冷媒过剩的状态信号包括冷媒过剩的第三状态信号和冷媒过剩的第四状态信号。
在本申请的一个实施例中,根据状态参数,控制制冷内机发送状态信号,包括:将状态参数分别与预设的至少一个状态识别策略进行匹配;根据状态参数和每个状态识别策略的匹配结果,控制制冷内机发出状态信号。
下面以具体的示例,对状态信号的生成过程中进行解释说明。
(1)可以通过制冷内机的内机电子膨胀阀的开度;空调的回风温度、空调的送风温度以及空调的回风温度与空调的送风温度之间的第一温差;以及空调的回风温度与设定的制冷温度之间的第二温差,即当满足下述3个公式时,可以控制制冷内机发出第一状态信号。

T en-T d,pre≧χ+2℃,并持续ε分钟以上;
T en-T s<1.5℃。
其中,Ten为回风温度,Td,pre为预测送风温度,Ts为内机设定制冷温度。
由此,通过将状态参数分别与预设的至少一个状态识别策略进行匹配,从而可以根据状态参数和每个状态识别策略的匹配结果,控制制冷内机发出状态信号,可变的目标过热度控制方法能适应室内与室外温差更大的情况,进一步提高可靠性,运行范围进一步能够扩宽。
在本申请的一个实施例中,如图4所示,上述的空调的控制方法,还包括以下步骤:
S401,检测并确认第一状态信号在预设的第一状态识别策略下触发,检测并确认第一状态信号的持续时长超出预设的第五时长。
具体地,第五时长可以为ε分钟,即需要满足下述两个条件。
T en-T d,pre<χ-2℃,并持续ε分钟以上;
T en-T s≧2℃。
即可说明第一状态信号在预设的第一状态识别策略下触发。
S402,检测并确认第一状态信号的持续时长超出第五时长,控制降低当前的目标过热度,直到第一状态识别策略触发发出第四状态信号,或者第一状态信号由预设的第二状态识别策略触发。
具体地,如果第一状态信号持续时长超过预设的第五时长,可以控制当前的目标过热度减1,如图5所示,目标过热度由SHS1至SHS2,直到第一状态识别策略触发发出第四状态信号,即:
T en-T d,pre≧χ+2℃,并持续ε分钟以上;
T en-T s<1.5℃。
或者第一状态信号由预设的第二状态识别策略触发,即:
制冷内机EXV开度≧λ 1pls,
T en-T d,pre<χ-2℃,
T en-T s≧2℃。
其中,Ten为回风温度,Td,pre为预测送风温度,Ts为内机设定制冷温度。

具体地,第六时长可以为ε分钟,即需要满足下述条件。
T d,pre≧ξ+2℃,并持续ε分钟以上;
其中,T d,pre为预测送风温度。
即可说明第二状态信号在预设的第三状态识别策略下触发。
S404,检测并确认第二状态信号的持续时长超出第六时长,控制增加当前的目标过热度,直到第三状态识别策略触发发出第三状态信号或者第二状态信号由预设的第四状态识别策略触发出。
具体而言,如果第二状态信号持续时长超过预设的第六时长,可以控制当前的目标过热度加1,如图5所示,目标过热度由SHS4至SHS3,直到第三状态识别策略触发发出第三状态信号,即:
T d,pre<ξ-2℃,并持续ε分钟以上;
或者第二状态信号由预设的第四状态识别策略触发,即:
制冷内机EXV开度≧λ 22pls,
T d,pre≧ξ+2℃。
其中,Td,pre为预测送风温度。
在本申请的一个实施例中,上述的空调的控制方法,还包括:识别状态参数分别与预设的至少一个状态识别策略进行匹配,检测并确认状态参数同时匹配第一状态识别策略和第二状态识别策略触发生成第一状态信号,获取第一状态识别策略和第二状态识别策略的优先级,控制发送优先级高的状态识别策略触发的第一状态信号;其中,第一状态识别策略和第二状态识别策略为用于对冷媒不足的状态进行识别的识别策略;检测并确认状态参数同时匹配第三状态识别策略和第四状态识别策略触发生成第三状态信号,获取第三状态识别策略和第四状态识别策略的优先级,控制优先级高的识别策略触发发送的第三状态信号;其中,第三状态识别策略和第四状态识别策略为用于对冷媒过剩的状态进行识别的识别策略。
具体而言,如果在状态参数与状态识别策略进行匹配的过程中同时匹配第一状态识别策略和第二状态识别策略触发生成第一状态信号,则需要判断第一状态识别策略和第二状态识别策略的优先级,如果第一状态识别策略高于第二状态识别策略,则控制第一状态识别策略触发的第一状态信号,如果第一状态识别策略低于第二态识别策略,则控制第二状态识别策略触发的第一状态信号;如果在状态参数与状态识别策略进行匹配的过程中同时 匹配第三状态识别策略和第四状态识别策略触发生成第三状态信号,则需要判断第三状态识别策略和第四状态识别策略的优先级,如果第三状态识别策略高于第四状态识别策略,则控制第三状态识别策略触发的第三状态信号,如果第三状态识别策略低于第四态识别策略,则控制第四状态识别策略触发的第三状态信号。
需要说明的是,只有第一状态信号和第三状态信号时才需要识别优先级,在第二状态信号和第四状态信号时不需要识别优先级。
在本申请的一个实施例中,如图6所示,上述的空调的控制方法,还包括以下步骤:
S601,获取冷媒的进入温度。
其中,可根据进入温度和制冷内机的状态信号,判断是否进入内机防冻结控制流程。
具体地,相关技术中的制冷内机防冻结控制往往只判断冷媒进口的温度低于结霜点的时间来判断是否进行防冻结控制,而低温制冷的情况下,由于低压较低,进口状态往往低于结霜点,而冷媒流量较少,容易过热,因此换热器绝大部分都会处于高于结霜点的状态,而低于结霜点部分也不容易累积霜,不需要进行防冻结控制。在压力控制的情况下,低温混合模式下外机作为蒸发器时,以外机目标低压作为控制目标,无法控制制冷内机的输出。
因此,为了更好的控制进入或退出内机防冻结流程,可以首先获取冷媒的进入速度,并根据进入速度和制冷内机的状态信号,从而判断是否进入内机防冻结控制流程。
S602,检测并确认进入温度小于或者等于预设的第一温度阈值且状态信号非冷媒过剩的状态信号,控制进入内机防冻结流程;其中,冷媒过剩的状态信号包括第二状态信号和第三状态信号。
具体地,进入温度小于或者等于预设的第一温度阈值需要持续一定的时长。其中,第一预设阈值可以为-1℃。
具体而言,当冷媒进入内机的温度<=-1℃时,并且状态信号不是冷媒过剩的状态信号,可以控制进入内机防冻结流程。
S603,持续检测进入温度,检测并确认进入温度大于或者等于预设的第二温度阈值,或者状态信号为冷媒不足的状态信号,控制退出内机防冻结流程;其中,冷媒不足的状态信号包括第一状态信号和第四状态信号。
具体地,进入温度大于或者等于预设的第二温度阈值需要持续一定的时长。其中,第二预设阈值可以为σ℃。
具体而言,当冷媒进入内机的温度>=σ℃时,或者状态信号为冷媒不足的状态信号,可以控制退出内机防冻结流程。
在本申请的一个实施例中,上述的空调的控制方法,还包括:采集样本数据,利用样本数据,对构建的送风温度的预测模型进行训练,得到目标预测模型;采集用于预测送风 温度的预测数据,将预测数据输入到目标预测模型中,得到送风温度。
举例而言,如图7所示,送风温度预测方法的步骤如下:
S701,确定预测模型、筛选预测所需自变量。
S702,初始化基本实验样本的个数m 0及需要增加的样本个数n=0。
S703,根据确定的自变量与因变量收集相关样本并达到初始个数,对这些样本中的值进行归一化处理。
S704,把样本随机分为α%训练用样本及β%检验用样本。
S705,进行多元回归分析,并获得多元回归方程。
多元回归方程公式如下:
Y=ε 01·X 12·X 2+….+ε n·X n
S706,使用检验样本,检验回归方程的误差θ是否小于ξ:如果小于,则确定最终的多元回归方程;否则增加样本个数,并重复步骤S702-S706。
具体地,因变量:送风温度Y,自变量:冷媒进入温度X 1、冷媒出口温度X 2、换热器中间冷媒温度X 3、回风温度X 4、标称能力X 5
确定多元回归方程为:
Y=ε 01·X 12·X 23·X 34·X 45·X 5
其中,结合表1和表2,总共178个数据样本,通过多元回归得到回归方程:
Y=-3.8841172169081-3.8841172169081X 1
+0.543407068248543X 2+0.373026318127632X 3
+0.20128670841994X 4+0.0103436792103981X 5
其中,送风温度预测值如图8所示,误差值如图9所示,误差为±3 oC。
