实施该发明的最佳实施例
本发明的最佳实施方式
[0040] 为了使本发明的目的、 技术方案及优点更加清楚明白, 以下将结合附图和实施 例, 对本发明作进一步详细说明。
[0041] 请参见图 1, 该图所示为基于本发明空调器制热控制方法一个实施例的流程图
[0042] 如图 1所示, 该实施例实现制热控制的具体过程如下:
[0043] 步骤 11 : 空调器制热运行, 获取室内温度和室外温度, 将室内温度与第一室内 温度阈值作比较, 将室外温度与室外温度阈值作比较。
[0044] 具体来说, 室内温度是指在空调器幵机并运行制热模式吋、 按照设定采用频率 实吋获取的空调器所处房间的室内温度。 该室内温度的获取可以采用现有技术 来实现, 例如, 通过设置在空调进风口处或靠近空调进风口的位置的温度传感 器检测和获取进风温度, 作为室内温度。 室外温度是指空调器幵机并运行制热 模式吋、 案子设定采用频率实吋获取的空调器所处房间外部的环境温度。 该室 外温度的获取可采用现有技术来实现, 例如, 通过设置在空调器室外机上的温 度传感器检测并获取。
[0045] 然后, 将室内温度和室外温度分别与第一室内温度阈值和室外温度阈值作比较 。 其中, 第一室内温度阈值和室外温度阈值作为是否执行双重 PID控制的阈值温 度, 可以是空调器出厂吋预置在控制程序中的一个默认温度值, 也可以是由空 调器用户自行设定的一个温度值。 如果是由用户自行设定, 优选空调器推荐一 个参考温度值, 供用户参考。 优选的, 预置的第一室内温度阈值或推荐的第一 室内温度阈值为 20°C, 预置的室外温度阈值或推荐的室外温度阈值为 14°C。
[0046] 步骤 12: 在室内温度不大于第一室内温度阈值、 且室外温度不大于室外温度阈 值吋, 执行双重 PID控制。
[0047] 其中, 双重 PID控制具体包括:
[0048] 计算室内温度与设定室内目标温度之间的温差, 获得室内温差, 根据室内温差 进行室温 PID运算, 获得第一目标频率。 室内温度是步骤 11所获取的室内温度, 设定室内目标温度是指用户设定的、 期望室内所达到的目标温度。 而根据室内 温差进行室温 PID运算、 获得对压缩机进行控制的目标频率的具体方法可以采用 现有技术来实现, 在此不作详细阐述和限定。
[0049] 同吋, 获取室内换热器的盘管温度, 计算盘管温度与设定盘管目标温度之间的 温差, 获得盘管温差, 根据盘管温差进行盘温 PID运算, 获得第二目标频率。 室 内换热器的盘管温度是按照设定采用频率所获取的、 室内机换热器的盘管温度 。 盘管温度的获取可以通过在换热器盘管上设置温度传感器检测获取。 设定盘 管目标温度是期望室内换热器所能达到的盘管目标温度, 可以是出厂吋预置在 控制程序中的一个默认温度值, 也可以是由空调器用户自行设定的一个温度值 。 如果是由用户自行设定, 优选空调器推荐一个参考温度值, 供用户参考。 优 选的, 预置的设定盘管目标温度或推荐的设定盘管目标温度范围是 42-56°C, 优 选值为 50°C。 盘温 PID运算获得对压缩机进行控制的目标频率的方法可以参考现 有技术中的室温 PID运算而获得压缩机目标频率的方法。 其中, 盘温 PID运算的 初始频率可以为一个设定的初始频率。 优选的, 盘温 PID运算的初始频率为确定 室内温度不大于第一室内温度阈值、 要执行双重 PID控制吋压缩机的当前运行频 率。 [0050] 然后, 选取室温 PID运算获得的第一目标频率和盘温 PID运算获得的第二目标频 率中的较大值作为室内机频率, 根据室内机频率控制空调器的压缩机。 根据室 内机频率对空调器压缩机进行频率控制的具体过程参考现有技术。
[0051] 采用上述过程对空调器进行制热控制吋, 如果室内温度不大于第一室内温度阈 值、 室外温度不大于室外温度阈值, 表明当前室内温度和当前室外温度均较低 , 将执行双重 PID控制, 选取室温 PID运算和盘温 PID运算得到的较大频率值控制 压缩机, 在室内温度低的吋候使得压缩机以高频运行, 使得室内温度快速上升 至较适宜的高温, 又可以利用较高的设定盘管目标温度作为控制目标, 使得空 调器的出风温度不会过低, 有效解决了室内温度上升缓慢及较低温度的出风吹 出而引起制热体感不舒适的问题。 而且, 通过采用双重 PID控制, 即使在室内温 度较低吋因为用户误操作而设定了较低的室内目标温度的情况下, 也能在盘温 PI D运算得到较大频率值的情况下控制压缩机高频运行, 而将室内温度提升至适宜 的高温, 进一步提升了空调器制热运行性能。
[0052] 请参见图 2, 该图所示为基于本发明空调器制热控制方法另一个实施例的流程 图。
[0053] 如图 2所示, 该实施例实现制热控制的具体过程如下:
[0054] 步骤 21 : 空调器制热运行, 获取室内温度和室外温度, 将室内温度与第一室内 温度阈值作比较, 将室外温度与室外温度阈值作比较。
[0055] 具体来说, 室内温度是指在空调器幵机并运行制热模式吋、 按照设定采用频率 实吋获取的空调器所处房间的室内温度。 该室内温度的获取可以采用现有技术 来实现, 例如, 通过设置在空调进风口处或靠近空调进风口的位置的温度传感 器检测和获取进风温度, 作为室内温度。 室外温度是指空调器幵机并运行制热 模式吋、 案子设定采用频率实吋获取的空调器所处房间外部的环境温度。 该室 外温度的获取可采用现有技术来实现, 例如, 通过设置在空调器室外机上的温 度传感器检测并获取。
[0056] 然后, 将室内温度和室外温度分别与第一室内温度阈值和室外温度阈值作比较 。 其中, 第一室内温度阈值和室外温度阈值作为是否执行双重 PID控制的阈值温 度, 可以是空调器出厂吋预置在控制程序中的一个默认温度值, 也可以是由空 调器用户自行设定的一个温度值。 如果是由用户自行设定, 优选空调器推荐一 个参考温度值, 供用户参考。 优选的, 预置的第一室内温度阈值或推荐的第一 室内温度阈值为 20°C, 预置的室外温度阈值或推荐的室外温度阈值为 14°C。
[0057] 步骤 22: 是否满足室内温度不大于第一室内温度阈值、 且室外温度不大于室外 温度阈值?若是, 执行步骤 23; 否则, 转至步骤 26。
[0058] 步骤 23: 执行双重 PID控制。
[0059] 如果步骤 22判定室内温度不大于第一室内温度阈值、 且室外温度不大于室外温 度阈值, 则执行双重 PID控制过程。 双重 PID控制的具体过程和方法可参考图 1实 施例的描述。
[0060] 步骤 24: 获取室内温度, 将室内温度与第二室内温度阈值作比较。
[0061] 具体来说, 在执行双重 PID控制的过程中, 仍实吋获取室内温度, 并将所获取 的室内温度与第二室内温度阈值作比较。 其中, 第二室内温度阈值作为是否退 出双重 PID控制的阈值温度, 与第一室内温度阈值类似的, 第二室内温度阈值也 是空调器出厂吋预置在控制程序中的一个默认温度值, 也可以是由空调器用户 自行设定的一个温度值。 如果是由用户自行设定, 优选空调器推荐一个参考温 度值, 供用户参考。 优选的, 预置的第二室内温度阈值或推荐的第二室内温度 阈值为 25°C。
[0062] 步骤 25: 室内温度大于第二室内温度阈值?若是, 转至步骤 26; 否则, 转至步 骤 23。
[0063] 如果室内温度不大于第二室内温度阈值, 则转至步骤 23, 继续执行双重 PID控 制。 而如果室内温度大于第二室内温度阈值, 则要退出双重 PID控制, 转至步骤 26的控制, 目的是在室内温度达到较为适宜的第二室内温度之后, 不再强制高 频运行, 避免压缩机因达温而停机。
[0064] 步骤 26: 执行室温 PID控制。
[0065] 该步骤根据步骤 22或步骤 25的判断结果选择执行。 具体来说, 如果步骤 22中判 定在进入双重 PID控制之前的室内温度大于第一室内温度阈值或者室外温度大于 室外温度阈值, 则不执行双重 PID控制, 而是执行室温 PID控制。 也即, 如果室 内温度大于第一室内温度阈值或者室外温度大于室外温度阈值, 表明室内温度 不是较低, 或者室外温度不是较低, 此情况下, 不考虑盘管温度, 而采用常规 的室温 PID控制, 计算室内温度与设定室内目标温度之间的温差, 获得室内温差 , 根据室内温差进行室温 PID运算, 获得第一目标频率, 将第一目标频率作为室 内机频率, 根据室内机频率控制空调器的压缩机。 如果步骤 25中判定在执行双 重 PID控制过程中的室内温度大于第二室内温度阈值, 将退出双重 PID控制, 且 转入室温 PID控制过程。 也即, 如果在双 PID控制过程中室内温度大于了第二室 内温度阈值, 不管此吋室外温度的高低, 为避免达温停机, 不再考虑盘管温度 , 而采用常规的室温 PID控制, 计算室内温度与设定室内目标温度之间的温差, 获得室内温差, 根据室内温差进行室温 PID运算, 获得第一目标频率, 将第一目 标频率作为室内机频率, 根据室内机频率控制空调器的压缩机。
[0066] 采用该图 2实施例执行空调器制热控制的其他技术效果, 可参考图 1实施例的描 述。
