具体实施方式
本公开内容提供了新风系统控制方法、新风系统及空调器，通过利用本公开内容的一个或多个实施方式解决了现有技术中新风系统换气策略的合理性差的技术问题。
为了更好的理解本公开内容，下面将结合说明书附图以及一些具体的实施方式对本公开内容进行详细的说明。
首先说明，本文中出现的术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
图1示出了依据本公开内容一些实施方式的新风系统的结构示意图。如图1所示，新风系统包括新风机110、多个出风管路120和多个回风管路 130，多个出风管路120分别一一对应连接新风机110的出风口111与多个分区(比如图1所示的分区1、分区2和分区3)，多个回风管路130分别一一对应连接新风机110的回风口112与多个分区。图1中，新风机110吹出的风通过多个出风管路120分别吹向多个分区，多个分区内的空气再分别通过多个回风管路130回到新风机110并吹出分区外，实现换气。
如图1所示，在一些实施方式中，多个出风管路120中每个出风管路120的一端均连接新风机110的出风口111，多个出风管路120的另一端与多个分区一一对应连接。多个回风管路130中每个回风管路130的一端均连接新风机110的出风口111，多个回风管路130的另一端与多个分区一一对应连接。以有三个分区为例，新风系统需要设置三个出风管路120和三个回风管路130。
图2示出了依据本公开内容一些实施方式的新风系统控制方法的流程图。如图2所示，依据本公开内容一些实施例的新风系统控制方法包括如下步骤S1～S2。
步骤S1，获取多个分区中每个分区所处环境的空气污染指数。
步骤S2，根据每个分区对应的空气污染指数控制新风系统的换气控制参数。其中，新风系统的换气控制参数决定了新风系统对分区的换气效果。
通过利用本公开内容的一个或者多个实施方式，能够根据每个分区对应的空气污染指数控制新风系统的换气控制参数。由于每个分区对应的空气污染指数代表了该分区自身的空气质量现状，这相当于能够根据分区自身的空气质量现状确定新风系统的换气控制策略，使得新风系统对分区的换气策略与分区自身的空气质量现状相适应，从而提高了新风系统换气策略的合理性。
本公开内容提供了多种换气控制参数以及多种根据空气污染指数控制换气控制参数的策略，下文将分别介绍。
在一些实施方式中，新风系统的换气控制参数可以包括新风机110的出风强度。相应地，在步骤S2中，根据每个分区对应的空气污染指数控制新风系统的换气控制参数，可以包括：根据多个分区对应的多个空气污染指数控制新风机110的出风强度。可以理解的是，新风机110的出风强度越高，各个分区的风量和风速越大，就可以使分区的换气效果更好。多个分区对应的多个空气污染指数越大，新风机110的出风强度越高，这样就可以快速对 多个分区进行换气。
根据本公开内容提供的新风系统控制方法，根据多个分区对应的多个空气污染指数控制新风机110的出风强度又可以有多种方式：可以根据多个分区对应的多个空气污染指数的总和、平方和或者权重和控制新风机110的出风强度。因此，在一些实施方式中，步骤S2可以包括：根据多个分区对应的多个空气污染指数的总和控制新风机110的出风强度。根据多个空气污染指数的总和控制出风强度又有可以多种方式。在一些实施方式中，控制新风机110的出风强度与多个分区对应的多个空气污染指数的总和成正比。在另一些实施方式中，根据多个空气污染指数的总和控制新风机110的出风强度，可以包括：确定多个分区对应的多个空气污染指数的总和所处的第一指数区间；控制新风机110的出风强度为第一指数区间对应的目标强度，第一指数区间内的指数平均值越大，对应的目标强度越大。
在一些实施方式中，可以预先设定多个第一指数区间及其对应的目标强度。例如：0<S-API≤150对应的目标强度为第一强度(代表低风)、150<S-API≤300对应的目标强度为第二强度(代表中风)、300<S-API≤400对应的目标强度为第三强度(代表次高风)、400<S-API≤500对应的目标强度为第四强度(代表高风)、500<S-API≤600对应的目标强度为第五强度(代表强高风)、600<S-API对应的目标强度为第六强度(代表强劲风)，API(Air Pollution Index，空气污染指数)为单个分区的空气污染指数，S-API则表示多个分区对应的多个空气污染指数的总和。这样的第一指数区间与目标强度的对应，可以使多个分区的空气质量越差时，新风机110的出风强度越高。从而快速对多个分区进行换气，快速提高多个分区的空气质量。又可以使多个分区的空气质量较好时，新风机110的出风强度较弱，以降低新风机110的功耗。
在一些实施方式中，新风系统的换气控制参数还可以包括每个分区对应的新风控制参数。相应地，在步骤S2中，根据每个分区对应的空气污染指数控制新风系统的换气控制参数，还可以包括：根据每个分区对应的空气污染指数，控制该分区对应的新风控制参数。每个分区对应的新风控制参数可以有不同类型，下文将分别介绍。
图4、图5和图6分别示出了依据本公开内容的单个分区的一种换气原理图。如图4～图6所示，在一些实施方式中，新风系统中每个出风管路120可以设有风阀121。每个分区对应的新风控制参数可以包括该分区对应的风 阀121的开度。可以理解的是，某个分区对应的风阀121的开度越大，该分区获得的风量越多，提高分区空气质量的效果越好。
如图1所示，在一些实施方式中，新风系统中每个回风管路130中可以设有风机133。每个分区对应的新风控制参数可以包括该分区对应的风机133的档位。可以理解的是，某个分区对应的风机133的档位越高，该分区内的空气的排出速度越快，提高分区空气质量的效率越高。
在一些实施方式中，新风系统中每个出风管路120中设有风阀121且每个回风管路130中设有风机133。每个分区对应的新风控制参数可以包括该分区对应的风阀121的开度和风机133的档位。
无论每个分区对应的新风控制参数仅包括该分区对应的风阀121的开度、仅包括该分区对应的风机133的档位，或者包括该分区对应的风阀121的开度和该分区对应的风机133的档位。在一些实施方式中，根据每个分区对应的空气污染指数，控制该分区对应的新风控制参数可以包括：控制每个分区对应的新风控制参数与该分区对应的空气污染指数成正比。在另一些实施方式中，根据每个分区对应的空气污染指数，控制该分区对应的新风控制参数可以包括：确定每个分区对应的空气污染指数所处的第二指数区间；控制每个分区对应的新风控制参数为第二指数区间对应的目标控制参数，第二指数区间内的指数平均值越大，对应的目标控制参数越大。
依据本公开内容的一个或者多个实施方式中，在每个分区对应的新风控制参数仅包括该分区对应的风阀121的开度时，可以控制每个分区对应的风阀121的开度与该分区对应的空气污染指数成正比，或者确定每个分区对应的空气污染指数所处的第二指数区间，控制每个分区对应的风阀121的开度为第二指数区间对应的目标开度(即目标控制参数为目标开度)；在每个分区对应的新风控制参数仅包括该分区对应的风机133的档位时，可以控制每个分区对应的风机133的档位与该分区对应的空气污染指数成正比，或者确定每个分区对应的空气污染指数所处的第二指数区间，控制每个分区对应的风机133的档位为第二指数区间对应的目标档位(即目标控制参数为目标档位)；在每个分区对应的新风控制参数包括该分区对应的风阀121的开度和风机133的档位时，可以控制每个分区对应的风阀121的开度和风机133的档位与该分区对应的空气污染指数成正比，或者确定每个分区对应的空气污染指数所处的第二指数区间，控制每个分区对应的风阀121的开度和风机133的档位为第二指数区间对应的目标开度和目标档位(即目标控制参数包 括目标开度和目标档位)。
在一些实施方式中，对于第二指数区间，可以预先设定多个第二指数区间及其对应的目标开度和/或目标档位。例如：50<API≤100对应的目标开度为30°、目标档位为停止档，100<API≤150对应的目标开度为45°、目标档位为停止档，150<API≤200对应的目标开度为60°、目标档位为停止档，200<API≤300对应的目标开度为90°(全开)、目标档位为低档，300<API对应的目标开度为90°(全开)、目标档位为高档。其中，API(AirPollution Index，空气污染指数)为单个分区对应的空气污染指数。
依据本公开内容提供的一些实施方式，在每个分区对应的新风控制参数包括该分区对应的风阀121的开度和风机133的档位时，若某个分区对应的空气污染指数较小，该分区对应的风阀121还未达到全开，可以使风阀121的开度随空气污染指数的增大而增大，仅通过控制风阀121的开度来提升换气效果，无需打开风机133，以降低功耗。当某个分区对应的空气污染指数较大时，可能此时对应的风阀121已经全开，无法通过继续增大风阀121开度来提高换气效果，需要打开风机133来提高换气效率。因此，在每个分区对应的新风控制参数包括该分区对应的风阀121的开度和风机133的档位的情况下，在步骤S2中，根据每个分区对应的空气污染指数，控制该分区对应的新风控制参数，可以包括：分区对应的空气污染指数低于预设污染指数阈值时，该分区对应的风阀121打开、风机133关闭；分区对应的空气污染指数高于预设污染指数阈值时，该分区对应的风阀121全开、风机133打开。在一些实施方式中，预设污染指数阈值可以为200。这样在分区对应的风阀121全开而无法继续通过控制风阀121开度来提高换气效果时，可以通过风机133将空气质量较差的分区内部空气抽走，分区内部形成负压，有利于将新风引入到该分区，同时减少新风机110出风压力，增加新风机110回风压力，提高新风机110换气效率。
在一些实施方式中，针对每个回风管路130中设置有风机133，依据本公开内容一些实施方式的新风系统控制方法还可以包括如下步骤：监测新风系统的运行状态；若新风系统处于故障状态，则控制回风管路130连通外部环境与对应的分区，并控制风机133运行，以通过风机133将外部环境的空气抽向对应的分区。这样在新风系统发生故障时，可以通过风机133将外部空气直接抽向分区内，在新风系统失效时完成换气。
图3示出了依据本公开内容另一些实施例方式的新风系统的结构示意 图。如图3所示，本公开内容还提供一种新风系统。该新风系统包括新风机110、控制器140、多个检测器150、多个出风管路120和多个回风管路130；多个出风管路120分别一一对应连接新风机110的出风口111与多个分区，多个回风管路130分别一一对应连接新风机110的回风口112与多个分区，多个检测器150分别一一对应设置于多个分区；多个检测器150与控制器140通信连接，每个检测器150用于检测对应分区所处环境的空气污染指数；控制器140用于获取多个分区中每个分区对应的空气污染指数；根据每个分区对应的空气污染指数，控制新风系统的换气控制参数。
根据本公开内容提的一些实施方式，新风系统根据每个分区对应的空气污染指数，控制新风系统的换气控制参数，由于每个分区对应的空气污染指数代表了该分区自身的空气质量现状，相当于根据分区自身的空气质量现状确定新风系统的换气控制策略，新风系统对分区的换气策略与分区自身的空气质量现状相适应，提高了新风系统换气策略的合理性。
如图4、图5和图6所示，在一些实施方式中，回风管路130可以包括第一管路131和第二管路132。第一管路131连接对应的分区与回风口112，第二管路132连接对应的分区与回风口112(如图5所示)和/或对应的分区与外部环境(如图6所示)。第二管路132中设有风机133。
在一些实施方式中，第一管路131和第二管路132可以一直是导通的，也可以是导通与封闭可切换的，第一管路131和第二管路132的导通与封闭可以通过阀门来实现。如图4所示，在第一管路131导通且第二管路132封闭时，风机133不起作用。如图5所示，第二管路132导通对应的分区与回风口112且第一管路131封闭时，风机133正转，能够将对应的分区的空气抽向回风口112。控制器140可以根据每个分区对应的空气污染指数来控制风机133的档位，提高换气效率。如图6所示，第二管路132导通对应的分区与外部环境时，第一管路131封闭且风机133反转，能够将外部的空气抽向对应的分区。以使在新风系统发生故障时，可以通过风机133将外部空气直接抽向分区内，在新风系统失效时完成换气。
如图4、图5和图6所示，在一些实施方式中，新风系统还可以包括出风箱160和回风箱170，每个出风管路120中设有风阀121；多个出风管路120均通过出风箱160连接出风口111，多个回风管路130均通过回风箱170连接回风口112。出风箱160为单进口、多出口的结构，实现将多个出口管路与出风口111连接；回风箱170为单出口、多进口的结构，实现将多个回 风管路130与回风口112连接。
本公开内容还提供一种空调器，包括本公开内容的任一实施方式中新风系统。空调器根据每个分区对应的空气污染指数，控制新风系统的换气控制参数，由于每个分区对应的空气污染指数代表了该分区自身的空气质量现状，相当于根据分区自身的空气质量现状确定新风系统的换气控制策略，新风系统对分区的换气策略与分区自身的空气质量现状相适应，提高了新风系统换气策略的合理性。
基于与上述新风系统控制方法同样的发明构思，本公开内容还提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序在被处理器执行时实现本公开内容的任一实施方式中新风系统控制方法。

这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现 的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
尽管已描述了本公开内容的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本公开内容范围的所有变更和修改。
