本公开实施例提供的用于空调控制的方法，应用于水系统中央空调。该水系统中央空 调的末端可以包括风机盘管、空气处理器以及新风处理器。其中，风机盘管通过管路和水系统中央空调的冷热水机组连通，管路中设置有可调节阀开度的水阀，以调节进入风机盘管的水流量。
图1是本公开实施例提供的一个用于空调控制的方法的流程图。结合图1所示，本公开实施例提供一种用于空调控制的方法，以实现对上述水系统中央空调的控制，该方法可以包括：
S11，控制器获得空调的设定运行温度，以及用于调节空调能力的空间需求信息。
这里，设定运行温度可以根据用户的操作指令获得。具体地，用户可以通过空调关联的控制终端发出设置空调运行温度的操作指令。上述控制终端可以是空调遥控器，或者，可以是与空调建立无线通信的用户智能终端。可选地，无线通信的方式至少可以包括Wi-Fi通信、紫蜂协议通信和蓝牙通信中的一种或多种。上述用户智能终端，例如为移动设备、电脑，或浮动车中内置的车载设备等，或其任意组合。在一些实施例中，移动设备例如可以包括手机、智能家居设备、可穿戴设备、智能移动设备、虚拟现实设备等，或其任意组合。
或者，设定运行温度可以根据空调所在空间的室内环境参数获得。具体地，如果空调保存有室内相对湿度与设定运行温度之间的对应关系，和/或室内温度与设定运行温度之间的对应关系，则在室内相对湿度和/或室内温度满足各自的预设条件的情况下，调节空调的设定运行温度，以提高空调的智能化程度，减少用户的操作流程。其中，室内相对湿度的预设条件可以配置为，在室内相对湿度≥60％或≤40％。室内温度的预设条件可以配置为，在冬季且室内温度≥26℃或≤16℃；在夏季且室内温度≥27℃或≤22℃。这样，有利于保证大多数用户的身体健康，同时可以避免空调超负荷工作。
可选地，用于调节空调能力的空间需求信息，至少可以包括空调所在空间的空间面积和当前空间温度。对应地，分别可以通过设置于空间内的红外测距传感器和温度传感器快速、方便地获得上述空间需求信息。
S12，控制器根据设定运行温度和空间需求信息，确定当前空调能力。
可选地，控制器根据设定运行温度和空间需求信息，确定当前空调能力，可以包括：获得空调所在空间的空间面积和当前空间温度；根据设定运行温度、空间面积以及当前空间温度，确定当前空调能力。这样，综合空间需求信息和空调的设定运行温度的影响，有助于更精准地确定当前空调能力，从而在保证空调使用效果的同时减少空调的能耗，节约资源。而且，这样可以实现空间温度和进水流量的双重调节，提高用户的使用体验。
可选地，本公开实施例可以提供多种实现方式获得当前空间温度。下面举例说明。
一种方式下，确定空调开启的情况下，可以持续获得当前空间温度，以获得控制过程中当前空间温度的动态变化。
另一种方式下，确定空调开启的情况下，可以周期性地获得当前空间温度，例如每5分钟获取一次当前空间温度，以便在保持动态控制的同时减少数据处理量。
另一种方式下，确定空调开启的情况下，持续获得当前空间温度，在该当前空间温度和设定运行温度相等或者二者之间存在较小误差时，周期性地获得当前空间温度，进行当前空调能力的动态控制。
具体地，当前空调能力可以通过如下方式确定：
Q＝S×K×(T s-T ao)      (1)
其中，Q为当前空调能力，S为空间面积，K为空气的导热系数，T s为设定运行温度，T ao为当前空间温度。
这里，空气的导热系数K的取值为0.024瓦/米·度。
S13，控制器根据当前空调能力和空调末端的当前进水温度，确定空调末端的目标进水温度。
可选地，控制器根据当前空调能力和空调末端的当前进水温度，确定空调末端的目标进水温度，可以包括：
Figure PCTCN2022082922-appb-000002
其中，T s为目标进水温度，T j为当前进水温度，Q为当前空调能力，C为水的比热容系数，M为流量系数。
这里，水的比热容系数C的取值为4200焦耳/千克·摄氏度。
流量系数M，可以指在规定测试条件且管道保持恒定的压力的情况下，水流经阀门的流量数。不同的阀门产品，其流量系数不同。在本实施例中，流量系数M的取值可以为10～40。
具体地，结合公式(1)和(2)可知，当前空调能力Q与空间面积S、空气的导热系数K、空调的设定运行温度以及当前空间温度有关。因此，目标进水温度可以通过如下方式确定：
Figure PCTCN2022082922-appb-000003
其中，T s为目标进水温度，T j为当前进水温度，S为空间面积，K为空气的导热系数，T s为设定运行温度，T ao为当前空间温度，C为水的比热容系数，M为流量系数。
S14，在设定运行温度大于或等于目标进水温度的情况下，控制器根据当前进水温度和目标进水温度，调节空调末端的进水流量。
可选地，控制器根据当前进水温度和目标进水温度，调节空调末端的进水流量，可以包括：确定当前进水温度和目标进水温度的温度差值；根据温度差值，对进水流量进行比例积分调节。这样，可以根据温差快速准确地调节进水流量，改善空调控制系统的稳态性能，从而降低空调的能耗，避免资源浪费。
可选地，控制器调节空调末端的进水流量后，还可以包括：确定空调末端在调节后的进水流量下运行的运行时长大于或等于预设时长的情况下，获得新的空间温度和新的进水温度；在新的空间温度和设定运行温度不匹配的情况下，根据新的空间温度和新的进水温度进行流量调节。这样，可以根据不断变化的空间温度和进水温度调节空调末端的进水流量，从而实现空间温度和进水流量的双重调节，提高空调的智能化控制逻辑以及用户的使用体验。
这里，不匹配可以指，新的空间温度和设定运行温度误差较大。对应于此，最大允许误差可以为±1℃。
可选地，预设时长可以为15分钟～60分钟，优选为30分钟。
综上，采用本公开实施例提供的用于空调控制的方法，通过获得空调的设定运行温度，以及用于调节空调能力的空间需求信息，以便确定当前空调能力，并根据当前空调能力和空调末端的当前进水温度确定空调末端的目标进水温度；这样，在设定运行温度大于或等于目标进水温度的情况下，可以根据当前进水温度和目标进水温度调节空调末端的进水流量，以实现水流量的精准调节，降低空调系统的能耗，从而避免资源浪费，保证用户的使用体验。
可选地，该用于空调控制的方法，还可以包括：在设定运行温度小于目标进水温度的情况下，控制器控制用于调节进水流量的水阀关闭。这样，有助于更好地实现节能效果，避免资源浪费。
