本申请要求于2018年11月6日提交的中国专利申请第201811312349.3的优先权，该中国专利申请的全文通过引用的方式结合于此以作为本申请的一部分。
技术领域
本发明公开实施例涉及一种多联机空调系统内机阀的控制方法。
背景技术
目前随着对空调能效及舒适性要求的提高，因电子膨胀阀可以根据空调的实际负荷变动情况实现变流量节流，达到提高空调能效及舒适性的要求，因此，越来越多的厂家青睐采用电子膨胀阀来节流。目前采用电子膨胀阀节流的多联机空调系统高温工况下，制冷开启后电子膨胀阀的初始开度是固定的，如果外机存在脏堵、冷媒不足或安装环境恶劣，内机电子膨胀阀初始化过程中极易出现频繁保护停机，且一旦停机后下次无法正常启动，影响用户使用效果。
发明内容
有鉴于此，本公开实施例提出一种多联机空调系统内机阀的控制方法，以解决已知技术中由于外机存在脏堵、冷媒不足或安装环境恶劣，而使内机阀初始化过程中极易出现频繁保护停机的技术问题。
为达到上述目的，本公开的技术方案是这样实现的：
一种多联机空调系统内机阀的控制方法，其包括以下步骤：
步骤S1，获取标准排气温度T 0，启动空调器，检测室外环境温度T out，若T out>A，内机阀以原始化开度P 0运行；
步骤S2，当步骤S1中所述内阀机以原始化开度P 0运行预定时间后结束，检测实际排气温度T 1；
步骤S3，将步骤S2所述实际排气温度T 1与步骤S1所述标准排气温度 T 0进行比较，当T 1≥T 0时，对下次开机时所述内机阀的初始化开度P 1拟合修正，增大下次开机时所述内机阀的开度；当T 1＜T 0时，下次开机时所述内机阀的开度维持不变。
进一步的，步骤S3中所述当T 1≥T 0时，对下次开机时所述内机阀的初始化开度P 1拟合修正，包括：
步骤S31，当T 1≥T 0时所述空调器正常工作时，对下次开机时所述内机阀的初始化开度P 11拟合修正；
步骤S32，当T 1≥T 0时所述空调器出现保护停机时，记录停机时所述内机阀的开度P，对下次开机时所述内机阀的初始化开度P 12拟合修正。
进一步的，步骤S31中所述内机阀的初始化开度P 11拟合修正的计算公式为P 11＝P 0+K(T out-A)，其中5≤K≤20，A为标准室外环境温度。
进一步的，步骤S31中所述空调器包括多个室内机，且至少一个所述室内机处于启动状态。
进一步的，步骤S32中所述内机阀的初始化开度P 12拟合修正的计算公式为P 12＝P 0+0.4K 1(P-P 0)，K 1＝K*(T out-A)/(120-T 1)，其中5≤K≤20，A为标准室外环境温度。
进一步的，步骤S32中所述空调器包括多个室内机，且一个所述室内机处于启动后停机状态。
进一步的，步骤S1中所述标准排气温度T 0为100℃≤T 0≤110℃。
进一步的，步骤S1中所述原始化开度P 0为所述空调器启动时系统默认的内机阀开度。
进一步的，步骤S2中所述预定时间为1-3min。
相对于已知技术，本公开所述的多联机空调系统内机阀的控制方法具有以下优势：
(1)通过初始化过程中排气温度与室外温度，对内机阀初始化的开度进行精确的修正控制，避免下次开机内机阀初始化过程中排气温度过高，导致后续内机阀动作不够快，排气温度上升过快，导致出现保护停机现象；
(2)如果出现保护停机后，通过初始化过程中排气温度与室外温度，对内机阀初始化的开度进行精确的修正控制，降低下次排气保护停机的几率，系统能够正常启动运行。
本公开的另一技术方案在于提供一种空调器，包括非临时性计算机可读存储介质，所述存储介质存储有可执行程序，所述可执行程序被执行运行时，实现上述的方法。
相对于已知技术，本公开所述的空调器包括非临时性计算机可读存储介质，所述存储介质存储有可执行程序，所述可执行程序被执行运行时，实现上述的方法，并与所述的多联机空调系统内机阀的控制方法具有相同的优势，在此不再赘述。
附图说明
构成本公开的一部分的附图用来提供对本公开的进一步理解，本发明的示意性实施例及其说明用于解释本公开，并不构成对本公开的不当限定。在附图中：
图1为本发明实施例所述的多联机空调系统内机阀的控制方法流程图。
具体实施方式
需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
下面将参考附图并结合实施例来详细说明本公开。
实施例1
如图1，本实施例提供一种多联机空调系统内机阀的控制方法，其包括以下步骤：
步骤S1，获取标准排气温度T 0，启动空调器，检测室外环境温度T out，若T out>A，内机阀以原始化开度P 0运行；
步骤S2，当步骤S1中运行结束后，检测实际排气温度T 1；
步骤S3，将步骤S2实际排气温度T 1与步骤S1标准排气温度T 0进行比较，当T 1≥T 0时，对下次开机时内机阀的初始化开度P 1拟合修正，增大所述内机阀的开度增大下次开机时所述内机阀的开度；当T 1＜T 0时，下次开机时内机阀的开度维持不变。
其中步骤S1中标准排气温度T 0为100℃≤T 0≤110℃，原始化开度P 0为所述空调器启动时系统默认的内机阀开度，且步骤S1中内机阀以原始化 开度P 0运行的时间为1-3min，本实施例中可选为2min，即内机阀以原始化开度P 0运行2min后，内机阀开始进行自动调节。
步骤S31，当T 1≥T 0空调器正常工作时，对下次开机时所述内机阀的初始化开度P 11拟合修正，所述空调器包括多个室内机，此时多联机空调器中至少有一个室内机处于开启状态，即可以为单机启动，也可以为多机同时启动，此时内机阀的初始化开度P 11拟合修正的计算公式为P 11＝P 0+K(T out-A)，其中5≤K≤20，45℃≤A≤50℃。在高温工况下，通过初始化过程中排气温度与室外温度，对内机阀初始化的开度进行精确的修正控制，避免下次开机内机阀初始化过程中排气温度过高，导致后续内机阀动作不够快，排气温度上升过快，导致出现保护停机现象。
步骤S32，多联机空调器中有且仅有一个室内机处于开启状态，即为单机启动，当T 1≥T 0时所述空调器出现保护停机时，记录停机时所述内机阀的开度P，对下次开机时所述内机阀的初始化开度P 12拟合修正，内机阀的初始化开度P 12拟合修正的计算公式为P 12＝P 0+0.4K 1(P-P 0)，K 1＝K*(T out-A)/(120-T 1)，其中5≤K≤20，45℃≤A≤50℃。此计算公式的原理在于，如果第一次开度进行修正后，运行一段实现出现排气过高停机，说明之前初始开度修正后，排气温度还是很高，内机阀调节还是不够及时，故加大修正，K 1根据室外环境温度T out和初始化开度结束后排气温度T 1进行修正，也就是说环境温度T out越高及初始化开度退出排气温度越高，K 1修正的越大，因此，如果出现保护停机后，能够根据排气温度和室外温度进行拟合修正初始开度，降低下次排气保护停机的几率，系统能够正常启动运行。
因此，本实施例通过初始化过程中排气温度与室外温度，对内机阀初始化的开度进行精确的修正控制，避免下次开机内机阀初始化过程中排气温度过高，导致后续内机阀动作不够快，排气温度上升过快，导致出现保护停机现象；且单机启动时如果出现保护停机后，也可同样通过初始化过程中排气温度与室外温度，对内机阀初始化的开度进行精确的修正控制，降低下次排气保护停机的几率，使空调系统能够正常启动运行。
实施例2
本实施例为实施例1的应用实例，具体如下：
本实施例中假定环境温度T out>48℃，本实施例一种多联机空调系统内机 阀的控制方法，其包括以下步骤：
步骤S1，获取标准排气温度T 0为105℃，启动两台室内空调器，此时检测室外环境温度T out为55℃，内机阀以原始化开度P 0为160运行2min，即内机阀以原始化开度P 0运行2min后，内机阀开始进行自动调节；
步骤S2，当步骤S1中运行结束后，检测实际排气温度T 1为120℃；
步骤S3，将步骤S2实际排气温度T 1与步骤S1标准排气温度T 0进行比较，发现T 1>T 0时，对下次开机时内机阀的初始化开度P 11拟合修正，增大下次开机时所述内机阀的开度，即通过内机阀的初始化开度P 11的计算公式为P 11＝P 0+K(T out-48)计算，其中K可以选为20，获得下次开机时内机阀的初始化开度P 11＝160+20*(55-48)＝300，则下次开机时内机阀将以300作为原始化开度运行，因此，本实施例通过在高温工况下，通过初始化过程中排气温度与室外温度，对内机阀初始化的开度进行精确的修正控制，增大所述内机阀的开度，使其排气温度有所下降，避免下次开机内机阀初始化过程中排气温度过高，导致后续内机阀动作不够快，排气温度上升过快，导致出现保护停机现象。
实施例3
本实施例为实施例1的应用实例，具体如下：
本实施例中假定环境温度T out>45℃，本实施例一种多联机空调系统内机阀的控制方法，其包括以下步骤：
步骤S1，获取标准排气温度T 0为100℃，启动两台室内空调器，此时检测室外环境温度T out为50℃，内机阀以原始化开度P 0为190运行1min，即内机阀以原始化开度P 0运行1min后，内机阀开始进行自动调节；
步骤S2，当步骤S1中运行结束后，检测实际排气温度T 1为90℃；
步骤S3，将步骤S2实际排气温度T 1与步骤S1标准排气温度T 0进行比较，T 1＜T 0时，则下次开机时内机阀的开度维持不变，即下次开机时内机阀将以190作为原始化开度运行。
实施例4
本实施例为实施例1的应用实例，具体如下：
本实施例中假定环境温度T out>48℃，本实施例一种多联机空调系统内机阀的控制方法，其包括以下步骤：
步骤S1，获取标准排气温度T 0为105℃，启动一台室内空调器，此时检测室外环境温度T out为52℃，内机阀以原始化开度P 0为100运行3min，即内机阀以原始化开度P 0运行3min后，内机阀开始进行自动调节；
步骤S2，当步骤S1中运行结束后，检测实际排气温度T 1为110℃；
步骤S3，继续运行10min后出现保护停机，此时所述内机阀的开度P为200，将步骤S2实际排气温度T 1与步骤S1标准排气温度T 0进行比较，发现T 1>T 0时，对下次开机时内机阀的初始化开度P 12拟合修正，增大下次开机时所述内机阀的开度，即通过内机阀的初始化开度P 12的计算公式为P 12＝P 0+0.4K 1(P-P 0)，K 1＝K*(T out-A)/(120-T 1)计算，其中K可选为5，获得下次开机时内机阀的初始化开度P 12＝100+0.4*5*(52-48)/(120-110)*(200-100)＝180，则下次开机时内机阀将以180作为原始化开度运行，因此，本实施例单机启动时出现保护停机后，也可同样通过初始化过程中排气温度与室外温度，对内机阀初始化的开度进行精确的修正控制，降低下次排气保护停机的几率，使空调系统能够正常启动运行。
实施例5
