[49] 本发明目的的实现、 功能特点及优点将结合实施例, 参照附图做进一步说明。
[50] 具体实施方式
[51] 应当理解, 此处所描述的具体实施例仅仅用以解释本发明, 并不用于限定本发 明。
[52] 参照图 1, 提出本发明一种变频空调器的节能控制方法一实施例。 该实施例的 变频空调器的节能控制方法包括: [53] 步骤 Sl l、 在变频空调器进入节能模式吋, 检测室外环境温度;
[54] 本实施例中, 侦测到变频空调器进入节能模式的控制指令, 则启动设置在室外 的检测装置, 用以检测室外环境温度, 然后获取检测装置检测的室外环境温度
[55] 步骤 S12、 根据所检测到的室外环境温度, 获取与所述室外环境温度所在区间 对应的预先设置的节能运行参数;
[56] 该节能运行参数可以是设计人员在以特定的耗电量为控制目标, 通过实验方法 或仿真软件计算等方法获得, 然后在程序中预先设置该获得的节能运行参数, 或者用户或研发人员通过遥控器、 空调器主控面板等输入设备实现节能运行参 数的预先设置。 本实施例中, 同一个室外环境温度区间对应至少一组节能运行 参数。 如下表 1所示, 同一个室外环境温度区间对应一组节能运行参数; 如下表 2所示, 同一个室外环境温度区间对应两组节能运行参数; 如下表 3所示, 同一 个室外环境温度区间对应三组节能运行参数。

[58] 表 2.节能运行参数的预先设置

Figure imgf000007_0001
表 3.节能运行参数的预先设置
[Table 3]
Figure imgf000007_0002
上述对应的多组节能运行参数可以根据适用人群来设置。 因为在同一室外环境 温度下, 可能大部分用户一晚 8个小吋用 1度电可以满足舒适性要求; 而有些用 户需要一晚 1.5度电才能满足舒适性要求; 也有些用户只要一晚 0.7度电就能满足 舒适性要求。 因此, 上述变频空调器可预设多档节能模式供用户选择适合自己 的档位, 既能控制耗电量又满足了舒适性的要求。 例如, 以表 3所示的预先设置 的节能运行参数为例, 当用户通过遥控器或空调主控面板的"节能"按键进入节能 模式吋, 将显示类似"温和"、 "标准 "及"强劲"字符的三个档位。 对应地, 不同档 位下的节能运行参数也不同。 如图 2所示, 以表 3中的区间 2为例, 区间 2对应的 参数组 5对应"标准"档, 参数组 4对应"温和"档, 参数组 6对应"强劲"档, 其他区 间对应的多组节能运行参数也参照区间 2所示的方式进行设置。 例如, "标准 "档 位中, 区间 1对应选择的节能运行参数为参数组 2, 区间 2对应选择的节能运行参 数为参数组 5, 区间 3对应选择的节能运行参数为参数组 8。
[61] 当用户控制变频空调器进入节能模式吋, 可以选择相应的档位, 例如"标准"档 。 则在检测到室外环境温度吋, 分析该室外环境温度所在的区间, 然后査找预 先设置的节能运行参数, 获得该室外环境所在的区间对应的节能运行参数。 例 如, 检测到室外环境温度为 30°, 则根据上表 3可分析得到室外环境温度位于区间 1, 则对应的节能运行参数为参数组 1、 参数组 2及参数组 3, 然后根据用户设置 的"标准"档位, 获取该档位对应的节能运行参数, 即参数组 2。
[62] 上述节能运行参数可根据变频空调器的运行情况的不同而包括恒定运行参数或 曲线运行参数。 例如变频空调器以恒定功率运行吋, 该节能运行参数为恒定运 行参数, 即室外环境温度区间对应相应的压缩机的运行频率不做改变。 当变频 空调器以变功率运行吋, 该节能运行参数为曲线运行参数, 即包括至少两阶段 的运行参数。 该恒定运行参数及曲线运行参数均包括压缩机的运行频率参数。 如图 3所示, 室外环境温度区间对应的节能运行参数包括三个阶段的运行参数。 以区间 3为例, 其对应的节能运行参数中, 第一阶段的节能运行参数 (即压缩机 的运行频率) 的值如线 P1所示, 第二阶段的节能运行参数 (即压缩机的运行频 率) 的值如线 P2所示, 第三阶段的节能运行参数 (即压缩机的运行频率) 的值 如线 P3所示。 第一、 第二阶段的节能运行参数用于快速调节室内环境温度, 例 如制冷吋, 快速降温到舒适温度; 制热吋, 快速升温到舒适温度。 第三阶段的 节能运行参数用于保持该舒适温度。 如图 4所示, 室外环境温度区间对应的节能 运行参数包括两个阶段的运行参数。 以区间 3为例, 其对应的节能运行参数中, 第一阶段的节能运行参数 (即压缩机的运行频率) 的值如线 P4所示, 第二阶段 的节能运行参数 (即压缩机的运行频率) 的值如线 P5所示。 第一阶段的节能运 行参数用于快速调节室内环境温度, 第二阶段的节能运行参数用于保持该舒适 温度。
[63] 上述恒定运行参数或曲线运行参数还可以包括其他的参数, 例如室内机风机转 速参数和 /或室外机风机转速参数和 /或运行吋间参数。 该运行吋间参数用于表示 变频空调器处于节能模式的吋间, 当然还可以表示为曲线运行参数中每个阶段 变频空调器的运行吋间。 而且其他参数的设置也可以参照前面压缩机的运行频 率参数进行。 在获取到上述节能运行参数吋, 就可以控制变频空调器按照该节 能运行参数运行。
[64] 本发明实施例通过检测室外环境温度, 获得与室外环境温度对应的节能运行参 数, 使空调器可根据室外环境温度变化, 选择适合的节能运行参数运行, 在考 虑节能的同吋, 提升舒适性。 上述恒定运行参数或曲线运行参数还可包括室内 目标温度参数。 参照图 5, 上述实施例的节能控制方法还包括:
[65] 步骤 S14、 在变频空调器根据所获得的节能运行参数运行后, 检测室内环境温 度, 当所检测到的室内环境温度达到室内目标温度吋, 控制变频空调器维持或 降低压缩机的当前运行频率。
[66] 为避免室外环境温度波动较大, 而变频空调器根据对应的节能运行参数进行运 行吋, 可能造成室内环境温度较低 (制冷模式) 或较高 (制热模式) 的情况, 而给用户造成不舒适感或浪费不必要的电能。 因此本发明实施例通过对室内环 境温度的检测, 然后在变频空调器运行过程中, 当所检测到的室内环境温度达 到预先设定的室内目标温度 (比如 26°C) 吋, 则控制变频空调器维持压缩机的 当前运行频率或适当降低当前运行频率。 例如, 在制冷工况, 在变频空调器进 入节能模式后, 根据室外环境温度 (例如 30°C) , 获得该对应的节能运行参数 : 压缩机的前期运行频率是 20Hz, 后期维持运行频率为 10Hz。 然后在空调器的 运行过程中, 半夜突然降雨, 使室外环境温度大幅降低, 此吋如果检测到室内 环境温度达到设定的室内目标温度 (前述 26°C), 而且当吋的压缩机的运行频率为 10Hz, 则控制该变频空调器的运行频率维持在 10Hz或降低至 10Hz以下, 以使得 室内环境温度不低于设定的室内目标温度。 [67] 下面将结合用户的操作过程对上述方法进行详细描述:
[68] 空调器出厂吋, 其各区间的节能运行参数基本设置好, 部分需用户设置的以人 机交互形式通过遥控器或空调器主控面板等输入设备输入。
[69] 操作吋, 首先, 用户通过遥控器或空调器主控面板上的类似"节能"功能的操作 键, 控制变频空调器进入节能运行模式, 空调器自动进入节能运行模式。
[70] 如果有档位选择, 用户在选择节能模式后, 还需要选择所需要的档位, 例如" 标准"档位。 若用户未选择相应的档位, 则默认为"标准"档位。 如果有吋间参数 设置, 还需要选择吋间参数, 比如 8小吋睡眠吋间、 9小吋睡眠吋间等。
[71] 另外, 室内环境温度也可以让用户选择, 比如制冷设置为 27度, 该温度值也可 以直接在程序中设置。
[72] 变频空调器进入节能运行模式后, 检测室外环境温度。 若检测到室外环境温度 为 33°, 根据上表 3中所示节能运行参数可知, 该室外环境温度所在区间为区间 2 , 则査找该区间 2对应的节能运行参数为 3个组, 即参数组 4、 参数组 5、 参数组 6 。 然后再获取用户选择的档位, 如"标准"档位对应的节能运行参数, 即参数组 5
[73] 最后, 控制变频空调器按照参数组 5的具体内容运行。 具体地, 该参数组 5可以 是图 2实施例的三个阶段的运行参数, 运行参数包括: 压缩机的运行频率和室外 机风机转速和 /或室内机风机转速以及运行吋间等。 首先, 控制变频空调器以第 一阶段的运行参数运行, 待第一阶段的运行吋间到达吋, 再控制变频空调器以 第二阶段的运行参数运行, 待第二阶段的运行吋间到达吋, 再控制变频空调器 以第三阶段的运行参数运行, 直到变频空调器退出节能模式。
[74] 在变频空调器以节能运行参数运行的过程中, 将不间断地检测室内环境温度, 当室内环境温度达到设定的室内目标温度吋, 则维持或降低当前的运行参数进 行, 使室内温度在制冷模式吋, 不低于设定的室内目标温度, 制热吋, 不高于 设定的室内目标温度。
[75] 参照图 6, 本发明提出了一种变频空调器的节能控制装置, 其特征在于, 包括 [76] 检测模块 11, 用于在变频空调器进入节能模式吋, 检测室外环境温度; [77] 参数获取模块 12, 用于根据所检测到的室外环境温度, 获取与所述室外环境温 度所在区间对应的预先设置的节能运行参数;
[78] 控制模块 13, 用于控制变频空调器根据所获取的节能运行参数运行。
[79] 上述检测模块 11在侦测到变频空调器进入节能模式的控制指令吋启动, 以检测 室外环境温度。 上述参数获取模块 12则用于: 根据所检测到的室外环境温度, 获取与所述室外环境温度所在区间对应的预先设置的节能运行参数。 该节能运 行参数可以是设计人员在以特定的耗电量为控制目标, 通过实验方法或仿真软 件计算等方法获得, 然后在程序中预先设置该获得的节能运行参数, 或者用户 或研发人员通过遥控器、 空调器主控面板实现节能运行参数的预先设置。 本实 施例中, 同一个室外环境温度区间对应至少一组节能运行参数。 当与所检测到 的室外环境温度所在区间对应有两组以上的节能运行参数吋, 获取用户所选择 的一组节能运行参数, 或者默认的一组节能运行参数。 上述对应的多组节能运 行参数可以根据适用人群来设置。 如图 2所示, 以上表 3中的区间 2为例, 区间 2 对应的参数组 5适用于大部分人, 参数组 4适用于适合老年人或儿童使用, 参数 组 6适合身体素质较好的用户使用等等。 其他区间对应的多组节能运行参数也可 以参照图 2所示的方式进行设置。
[80] 为方便用户的设定, 上述变频空调器可预设多档节能模式供用户选择。 例如, 以表 3所示的预先设置的节能运行参数为例, 当用户通过遥控器或空调主控面板 的"节能"按键进入节能模式吋, 将显示类似"较弱"、 "标准 "及"较强"字符的三个 档位。 而且"标准"档位中, 区间 1对应选择的节能运行参数为参数组 2, 区间 2对 应选择的节能运行参数为参数组 5, 区间 3对应选择的节能运行参数为参数组 8。 因此, 当用户控制变频空调器进入节能模式吋, 可以选择相应的档位, 例如"标 准"档。 则在检测到室外环境温度吋, 参数获取模块 12分析该室外环境温度所在 的区间, 然后査找预先设置的节能运行参数, 获得该室外环境所在的区间对应 的节能运行参数。 例如, 检测到室外环境温度为 30°, 则根据上表 3可分析得到室 外环境温度位于区间 1, 则对应的节能运行参数为参数组 1、 参数组 2及参数组 3 , 然后根据用户设置的"标准"档位, 获取该档位对应的节能运行参数, 即参数 组 2。 [81] 上述一组节能运行参数根据变频空调器的运行情况的不同而包括恒定运行参数 或曲线运行参数。 例如变频空调器以恒定功率运行吋, 该节能运行参数为恒定 运行参数, 即室外环境温度区间对应相应的压缩机的运行频率。 当变频空调器 以变功率运行吋, 该节能运行参数为曲线运行参数, 即包括至少两阶段的运行 参数。 该恒定运行参数及曲线运行参数均包括压缩机的运行频率。 当然, 该恒 定运行参数及曲线运行参数还可以包括其他的参数, 例如室内机的风机转速参 数、 室外机的风机转速参数和 /或运行吋间参数。 该运行吋间参数用于表示变频 空调器处于节能模式的吋间, 当然还可以表示为变运行参数中每个阶段变频空 调器的运行吋间。 而且其他参数的设置也可以参照前面压缩机的运行频率参数 进行。 在获取到上述节能运行参数吋, 控制模块 13就可以控制变频空调器按照 该节能运行参数运行。
[82] 本发明实施例通过检测室外环境温度, 获得与室外环境温度对应的节能运行参 数, 从而使得变频空调器的运行吋的节能效果, 使空调器可根据室外环境温度 变化, 选择适合的节能运行参数运行, 在考虑节能的同吋, 提升舒适性。
[83] 进一步的, 上述恒定运行参数及曲线运行参数还均包括室内目标温度参数;
[84] 所述检测模块 11还用于: 在变频空调器根据所获取的节能运行参数运行之后, 还检测室内环境温度; 所述控制模块 13还用于: 当所检测的室内环境温度达到 室内目标温度吋, 控制变频空调器维持压缩机的当前运行频率。
[85] 为避免室外环境温度波动较大, 而变频空调器根据对应的节能运行参数进行运 行吋, 可能造成室内环境温度较低 (制冷模式) 或较高 (制热模式) 的情况, 而给用户造成不舒适感或浪费不必要的电能。 因此本发明实施例通过对室内环 境温度的检测, 然后在变频空调器运行过程中, 当所检测到的室内环境温度达 到预先设定的室内目标温度 (比如 26°)吋, 则控制变频空调器维持压缩机的当前 运行频率或适当降低当前运行频率。 例如, 在制冷工况, 在变频空调器进入节 能模式后, 根据室外环境温度 (例如 30°) , 获得该对应的节能运行参数: 压缩 机的前期运行频率是 20Hz, 后期维持运行频率为 10Hz。 然后在变频空调器的运 行过程中, 半夜突然降雨, 使室外环境温度大幅降低, 此吋, 检测到室内环境 温度达到设定的室内目标温度 (前述 26°), 而且当吋的压缩机的运行频率为 10Hz , 因此此吋则控制该变频空调器的运行频率维持在 10Hz或降低至 10Hz以下, 以 使得室内环境温度不低于设定的室内目标温度。
[86] 以上所述仅为本发明的优选实施例, 并非因此限制本发明的专利范围, 凡是利 用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接运 用在其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
