步驟 Sl l、 所述系统主机的控制器接收针对所述空调系统的输入指令, 并根据所述输 入指令, 产生针对所述系统主机及相应的所述辅助设备的运行请求信息。
在进行对空调系统的运行控制时, 首先需要接收针对所述空调系统的输入指令。其中, 所述针对所述空调系统的输入指令通常由用户执行, 当需要开启所述空调系统时, 所述输 入指令为开始运行指令; 当需要关闭所述空调系统时, 所述操作为停止运行指令。

本申请的实施例一公开一种空调系统运行控制方法, 应用该方法的空调系统包括系统 主机和辅助设备 , 所述系统主机内部设置有控制器, 所述系统主机与用于控制所述辅助设 备的一个或多个电控拒相连接, 并且所述辅助设备与相应的电控柜相连接。 本申请公开的 空调系统运行控制方法中, 所述系统主机的控制器接收针对所述空调系统的输入指令, 并 根据所述输入指令, 产生针对系统主机及相应的辅助设备的运行请求信息; 然后, 根据所 述运行请求信息, 控制系统主机执行相应的操作, 和 /或将所述运行请求信息传输至相应 的电控拒中, 控制相对应的辅助设备执行相应的操作。
通过本申请公开的空调系统运行控制方法, 只需用户产生输入指令, 即可实现对空调 系统的控制, 而不需要用户依次去控制各个电控柜才能实现对各个辅助设备的控制, 减少 了人力; 另外, 本申请公开的空调系统运行控制方法应用于空调系统的系统主机, 通过与 各个电控柜相连接的系统主机即可实现对空调系统的控制, 不需要再额外配置第三方设备, 也相应的节省了成本。
其中, 执行本申请的空调系统运行控制方法的系统主机, 为所述空调系统中的一个系 统主机。 当所述空调系统中具有多个系统主机时,可选择其中一个系统主机为主系统主机, 执行本申请的空调系统运行控制方法, 其他系统主机作为备用系统主机, 当主系统主机发 生故障时, 确定一个备用系统主机执行本申请的空调系统运行控制方法。
另外, 所述系统主机, 通常指的是空调系统中的冷水机组。
本申请所公开的空调系统运行控制方法中, 当需要开启或关闭所述空调系统时, 步驟 S11中所述的根据所述输入指令,产生针对系统主机及相应的辅助设备的请求信息,包括: 按照预定的顺序, 依次产生针对系统主机及各个辅助设备的运行请求信息。
在空调系统的一条水路中, 包括多个辅助设备, 并且执行开始运行操作, 以及停止运 行操作时,都各个辅助设备和系统主机具有一定的流程顺序,因此,需要按照预定的顺序, 依次产生针对系统主机及各个辅助设备的运行请求信息。
例如, 在需要空调系统执行开始运行操作时, 所述流程通常是阀门—► 水泵→冷却 塔风机→·系统主机, 这种情况下, 需要所述阀门、 水泵、 冷却塔风机和系统主机依次执 行相应的开始运行操作。 其中, 所述阀门通常指的是电动蝶阀。
因此,所述系统主机在接收到用户的输入指令后,确定需要所述空调系统开始运行时, 则按照上述顺序产生针对所述系统主机, 以及相应的辅助设备的开始运行的运行请求信息。 例如, 首先产生针对阀门的运行请求信息, 并将其传输至与阀门相连接的执行器电控拒, 以使所述阀门打开; 继而再产生水泵对应的运行请求信息, 并传输至与水泵相连接的水泵 电控柜, 以使所述水泵开始运行; 然后产生针对冷却塔风机的运行请求信息, 并将其传输 至所述冷却塔风机相连接的冷却塔电控柜, 以使所述冷却塔风机开始执行排送气体的操作; 再产生针对系统主机的运行请求信息, 使所述系统主机开始执行制冷的操作。
另外, 有时在开始的流程中, 在开启水泵后, 需要先使系统主机开始制冷, 再开启冷 却塔风机, 这种情况下, 在水泵开始运行后, 所述系统主机先产生针对系统主机的开始运 行指令, 在所述系统主机开始执行制冷操作后, 所述系统主机再产生针对冷却塔风机的开 始运行指令, 并将其传输至与所述冷却塔风机相连接的冷却塔电控拒即可。
另外, 关闭时的流程通常为: 系统主机 冷却塔风机—►水泵—► 阀门。 当需要所 述空调系统停止运行时, 用户会输入停止运行指令, 在接收到所述停止运行的指令后, 所 述系统主机会按照一定的顺序, 产生针对相应的辅助设备的停止运行请求信息, 以控制所 述的辅助设备和系统主机执行相应的停止运行操作。 例如, 所述系统主机在接收到停止运 行指令后, 首先产生针对系统主机的停止运行请求信息, 以使所述系统主机停止制冷。 然 后再产生针对冷却塔风机的停止运行请求信息, 传输至与所述冷却塔风机相连接的冷却塔 电控柜, 控制所述冷却塔风机停止运行; 再产生针对水泵的停止运行请求信息, 传输至与 所述水泵相连接的水泵电控柜, 以使所述水泵停止运行; 最后产生针对阀门的停止运行请 求信息, 传输至与所述阀门相连接的执行器电控拒, 控制所述阀门停止运行, 从而使空调 系统最终停止运行。
在按照预定的顺序, 依次产生相应的运行请求信息时, 可以预先设定各个运行请求信
息产生的时间间隔, 以便在产生某一运行请求信息后, 经过相应的时间间隔后, 再产生下 一个运行请求信息; 另外, 也可以在产生针对系统主机, 或辅助设备的某一运行请求信息 后, 根据所述系统主机, 或所述辅助设备反馈的运行信息, 确定其运行状态后, 再产生相 应的运行请求信息。
另外, 本申请公开的空调系统运行控制方法中, 在控制系统主机本身和辅助设备在执 行开始运行操作和停止运行操作时, 都遵循一定的流程, 若未按顺序执行, 有可能对系统 主机或辅助设备造成损坏, 因此, 本申请公开的空调系统运行控制方法还包括:
在接收到针对系统主机, 和 /或辅助设备的开启指令或关闭指令时, 判断所述系统主 机, 和 /或辅助设备是否满足开启条件或关闭条件, 若不满足, 则禁止所述系统主机, 和 / 或辅助设备开启或关闭。
通过该步骤, 实现了连锁保护功能。 通过所述连锁保护功能, 当不满足开启或关闭条 件时, 则禁止所述系统主机, 和 /或辅助设备开启或关闭, 避免对系统主机和 /或辅助设备 造成损坏。 其中, 判断某一设备是否满足所述开启或关闭条件, 通常即为判断该设备是否 满足开启或关闭的流程。 例如, 在开启流程中, 当阀门还未开启时, 用户输入针对系统主 机的开启指令, 这种情况下, 根据开启流程即可判断出所述系统主机当前还不满足运行条 件, 则会禁止所述系统主机执行制冷的操作。
另外, 当需要空调系统运行时, 系统主机下发针对阀门的开始运行指令后, 会将其传 输至与所述阀门相连接的执行器电控柜, 控制阀门开启。 当所述阀门开启后, 系统主机会 检测各个水泵的累积使用时间, 使累积使用时间较短的水泵优先开始运行, 然后根据反馈 的运行状态信息确定所述水泵开始运行后, 再依次选择累积使用时间较短的冷却塔风机、 系统主机优先开始运行。
当需要空调系统停止运行时, 系统主机根据停止流程, 依次获取相应设备的累积使用 时间, 使其中累积使用时间长的设备优先停止运行。
其中, 各个设备的累积使用时间可存储在执行本申请的空调系统控制方法的系统主机 的存储器中, 也可以由所述系统主机向电控柜中提取。
通过上述方案, 本申请公开的空调系统运行控制方法中, 会按最优原则选择性的开启 和停止各个设备, 提高了空调系统的使用寿命。
