具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
图1为根据一些实施例的一种空调器的结构图。如图1所示，本公开一些实施例的空调器1包括室外机2、室内机3、联机管4和遥控器5。室外机2和室内机3通过联机管4连接以传输冷媒。室外机2通常设置在户外，被配置为与室内环境换热。由于室外机2安装于户外，且室外机2与室内机3被墙壁阻隔，因此，图1中用虚线表示位于户外的室外机2和部分联机管4。
空调器1通过使用压缩机、冷凝器、膨胀阀和蒸发器来执行制冷循环。制冷循环包括一系列过程，涉及压缩、冷凝、膨胀和蒸发，并向已被调节和热交换的空气供应冷媒。空调器的制冷循环离不开冷媒，冷媒冷凝液化时放热、蒸发气化时吸热，并以此实现热量的交换和传递。
遥控器5被配置为响应于用户的操作，向空调器1发送对应于用户操作的指令，从而实现用户与空调器1之间的交互。遥控器5通过例如红外线与空调器1之间进行通信，从而发送用户的操作指令。
在一些实施例中，如图1所示，遥控器5包括液晶显示装置51和多个按钮52。多个按钮52包括运转开关按钮、温度设定按钮、风向设定按钮和风量设定按钮等。用户通过使用运转开关按钮、温度设定按钮、风向设定按钮和风量设定按钮等进行相关的操作。
例如，运转开关被配置为控制空调器1在运转和停止之间进行切换，即，用户可以通过按下运转开关按钮52，以使空调器1在运转和停止之间交替切换。温度设定按钮被配置为调整空调器1的预期制冷(或制热)温度。风向设定按钮被配置为调节室内机3送风的风向。风量设定按钮被配置为调节室内机3送风的风量大小。
图2为根据一些实施例的一种空调器的电路结构图。如图2所示，在一些实施例中，室外机2包括压缩机11、储液器15、室外换热器13和膨胀阀14。室内机3包括室内换热器16。或者，室外机2包括压缩机11、储液器15和室外换热器13。室内机3包括膨胀阀14和室内换热器16。也就是说，膨胀阀14既可以设置在室外机2中，也可以设置在室内机3中。依序连接的压缩机11、储液器15、室外换热器13、膨胀阀14和室内换热器16形成冷媒回路10，冷媒于冷媒回路10中循环流动，通过室外换热器13和室内换热器16分别与空气进行换热，以实现空调器1的制冷模式或制热模式。
压缩机11被配置压缩冷媒以使得低压冷媒受压缩形成高压冷媒。压缩机11从吸入口吸入冷媒，将在内部压缩后的冷媒从排出口对室内换热器16排出。
室外换热器13被配置为将室外空气与在室外换热器13中传输的冷媒进行热交换。例 如，室外换热器13在空调器1的制冷模式下作为冷凝器进行工作，使得由压缩机11压缩的冷媒通过室外换热器13将热量散发至室外空气而冷凝；室外换热器13在空调器1的制热模式下作为蒸发器进行工作，使得减压后的冷媒通过室外换热器13吸收室外空气的热量而蒸发。
室外换热器13包括第一出入口和第二出入口，第一出入口与储液器15连通，第二出入口与膨胀阀14连通。第一出入口和第二出口之间设置有传热管，冷媒在传热管中流动，传热管中的冷媒与室外空气之间进行热交换。
室内换热器16被配置为将室内空气与在室内换热器16中传输的冷媒进行热交换。例如，室内换热器16在空调器1的制冷模式下作为蒸发器进行工作，使得经由室外换热器13散热后的冷媒通过室内换热器16吸收室内空气的热量而蒸发；室内换热器16在空调器1的制热模式下作为冷凝器进行工作，使得经由室外换热器13吸热后的冷媒通过室内换热器16将热量散发至室内空气而冷凝。
室内换热器16包括第一出入口和第二出入口。第一出入口与压缩机11的排出口连通，第二出入口与膨胀阀14连通。第一出入口与第二出入口之间设置有传热管，冷媒在传热管中流动，传热管中的冷媒与室内空气进行热交换。
膨胀阀14连接于室外换热器13与室内换热器16之间，由膨胀阀14的开度大小调节流经室外换热器13和室内换热器16的冷媒压力，以调节流通于室外换热器13和室内换热器16之间的冷媒流量。例如，通过减小膨胀阀14的开度，使得通过膨胀阀14的冷媒的流路阻力增加，从而降低流通于室外换热器13和室内换热器16之间的冷媒流量；通过增大膨胀阀14的开度，使得通过膨胀阀14的冷媒的流路阻力减小，从而增大室外换热器13和室内换热器16之间的冷媒流量。例如，在制热模式下，从室内换热器16向室外换热器13流动的冷媒经膨胀阀14膨胀而减压。
储液器15分别连接室外换热器13与压缩机11的吸入口。在储液器15中，从室外换热器13流向压缩机11的冷媒被分离成气体冷媒和液体冷媒。储液器15向压缩机11的吸入口主要供给气体冷媒。
如图2所示，在一些实施例中，室外机2还包括室外风扇21和室外风扇马达21A，室外风扇马达21A驱动室外风扇21转动，且室外风扇马达21A的转速可变。室外风扇21在室外风扇马达21A的驱动下转动，以使气流通过室外换热器13，从而加快传热管中冷媒与室外空气之间的热交换。
图3为根据一些实施例的一种空调器的室内机的剖面图。
在一些实施例中，如图2和图3所示，室内机3还包括室内风机31和室内风机马达31A，室内风机马达31A驱动室内风机31转动，且室内风机马达31A的转速可变。室内风机31在室内风机马达31A的驱动下转动，以使气流通过室内换热器16，从而加快传热管中冷媒与室内空气之间的热交换。
在一些实施例中，室内换热器16为散热片管式的热交换器，例如，室内换热器16包括多个散热片以及贯穿多个散热片的多个传热管。或者，室内换热器16为扁平多孔管式的热交换器。本公开实施例不对室内换热器16的具体形式做限制。
本公开一些实施例提供的空调器1，具有热应激舒适功能(即舒适送风功能)。当所述热应激舒适功能开启时，空调器1会随着用户体感温度的不同而相应改变或维持当前送风速度。相应地，多个按钮52还包括热应激舒适功能开关按钮。热应激舒适功能开关按钮被配置为开启和关闭热应激舒适功能。用户可以根据实际舒适性需求自行设定预设风速上限值和预设风速下限值，以使用户所在位置处的体感温度处于适宜的范围内。
图4为根据一些实施例的一种空调器的框图。在一些实施例中，如图3和图4所示，空调器1还包括人体检测装置6和控制器7。人体检测装置6被配置为检测人体与室内机3的出风口72之间的距离和相对角度。例如，人体检测装置6为雷达传感器或红外热传感器。
控制器7被配置为控制压缩机11的工作频率、膨胀阀14的开度、室外风扇21的转速、室内风机31的转速以及获取人体检测装置6的识别信号。识别信号例如包括人体与室内机3的出风口72之间的距离和相对角度。控制器7与压缩机11、膨胀阀14、室外风扇21、室内风机31和人体检测装置6通过数据线相连以传输通信信息。
控制器7包括处理器。处理器可以包括中央处理器(central processing unit,CPU))、微处理器(microprocessor)和专用集成电路(application specific integrated circuit,ASIC)，且被配置为执行存储在耦合到控制器7的非暂态的计算机可读介质中的程序。
图5为根据一些实施例的一种空调器的控制器的一种执行方法的流程图。
在一些实施例中，如图5所示，控制器7被配置为执行步骤S11至步骤S16。
在步骤S11，判断热应激舒适功能是否开启，若是，则执行步骤S12，若否，则重新执行S11。
在步骤S12，获取人体检测装置6的识别信号和室内风机31(即风机)的当前转速。
例如，当控制器7判断空调器1的热应激舒适功能开启时，人体检测装置6实时检测人体与室内机3的出风口72之间的距离和相对角度，并将代表所述距离和所述相对角度的识别信号发送至控制器。
在步骤S13，根据该识别信号，判断室内机3的预设送风覆盖范围内是否存在人体，若是，则执行步骤S14。
例如，室内机3的预设送风覆盖范围为室内机3吹出的空调风所能覆盖的范围。也就是说，当用户处于室内机3的预设送风覆盖范围内时，室内机3可以通过导风机构改变送风方向，直吹用户，而当用户不处于室内机3的预设送风覆盖范围内时，则室内机3的送风无法直吹用户。
需要说明的是，室内机3的预设送风覆盖范围也就是导风机构的预设送风覆盖范围，室内机3的预设送风覆盖范围是根据室内机3的实际结构决定的，在此不做限定。
在步骤S14，根据人体与室内机3之间的距离和室内风机31的当前转速，计算用户所在位置处的风速。
在步骤S15，判断用户所在位置处的风速与预设风速上限值之间的大小关系，若用户所在位置处的风速高于所述预设风速上限值，则执行步骤S16。
在步骤S16，控制室内风机31降低转速。
例如，控制器7控制室内风机31降低转速，以使用户所在位置处的风速小于所述预设风速上限值，且大于所述预设风速下限值。
需要说明的是，当用户所在位置的风速大于或等于0.3m/s时，用户可以感受到风的存在。当用户所在位置的风速大于1m/s时，用户体感的标准有效温度则会降低，可能会使用户感到不适。例如，当风温为27℃时，1.0m/s的风速对应的标准有效温度比0.1m/s的风速对应的标准有效温度低3.5℃左右。在一些实施例中，所述预设风速上限值为0.6m/s至1.0m/s之间的任一值。例如，所述预设风速上限值为0.6m/s、0.8m/s、0.9m/s或1.0m/s。
可以理解的是，当室内机3送风的温度不变时，风速越大，人体感受到的标准有效温度越低，这是因为人体实际的感受同时受到风温和风速的影响。因此，当用户长时间使用空调器1吹风时，通过控制室内风机31降低转速，使用户所在位置处的风速小于所述预设风速上限值，且大于所述预设风速下限值，可以有效防止用户对冷热刺激的生理调节能力被削弱，有利于提高用户的使用体验，保障用户的健康。
图6为根据一些实施例的一种空调器的控制器的另一种执行方法的流程图。
在一些实施例中，如图6所示，在步骤S14之后，控制器7被配置为执行步骤S15’以及步骤S16至步骤S18。
在步骤S15’，判断用户所在位置处的风速与所述预设风速上限值和所述预设风速下限值之间的大小关系，若用户所在位置处的风速高于所述预设风速上限值，则执行步骤S16；若用户所在位置处的风速低于所述预设风速下限值，则执行步骤S17；若用户所在位置处 的风速处于所述预设风速下限值和所述预设风速上限值之间，则执行步骤S18。
在步骤S16，控制室内风机31降低转速。
在步骤S17，控制室内风机31提高转速。
例如，控制器7控制室内风机31提高转速，以使用户所在位置处的风速小于所述预设风速上限值，且大于所述预设风速下限值。
需要说明的是，当风速过低时，用户所感受到的风感较轻微，无法明显感受到温度的变化。因此，若风速过低，则控制室内风机31提高转速，以避免因风速过低而导致人体感受的体感温度过低，从而有效提高舒适性。
预设风速下限值可以根据实际舒适性需求进行设置，在此不做限定。例如，预设风速下限值为0.3至0.5m/s之间的任一值。例如，预设风速下限值为0.3m/s、0.4m/s、0.5m/s。
在步骤S18，控制室内风机31维持当前转速。
可以理解的是，若用户所在位置处的风速处于所述预设风速下限值和所述预设风速上限值之间，则表面风速适中，在此情况下，控制室内风机31转速不变，使人体感受的体感温度保持在合适水平，可以有效提高用户的舒适度。
在一些实施例中，用户所在位置的风速Vρ的计算公式为：
Vρ＝(K1*R+K2)*(1-(ρ/(K3*R+K4)))                      (1)
其中，Vρ为用户所在位置的风速，R为室内风机31当前的转速，ρ为人体与室内机3的之间的距离，K1和K3为转速系数，K2和K4为常数。
根据经验公式及其逆函数，用户所在处的风温Tρ的计算公式为：
Tρ＝K5*Te+ρ/(K3*R+K4)*(Ta-K5*Te)                   (2)
其中，Tρ为用户所在处的风温，Te为室内换热器16的盘管温度，Ta为回风温度，K5为温度系数。K1至K5均为经验参数，在实施时，可以通过对空调器1进行数据测试并拟合得到。
例如，当常数K1＝0.0017m/(rpm*s)，K2＝0.58m/s，K3＝0.0033m/rpm，K4＝1.3m，K5＝1.2，且室内风机31当前的转速R的单位为rpm，室内换热器16的盘管温度Te的单位为℃时，将上述参数带入公式1计算，可得出在不同室内风机31的转速下用户所在位置处的风温和风速，详见下表1。
表1不同室内风机31转速下的风速和风温
可以理解的是，当用户所在位置的风速过低时，需提高室内风机31的转速，以降低用户所在位置处的风温；当用户所在位置的风速过高时，需降低室内风机31的转速，以提高用户所在位置处的风温。
例如，当用户所在位置处的风速小于0.3m/s时，用户几乎感受不到风或风感较轻微， 因此，需要提高室内风机31的转速，以提高风速。当用户所在位置的风速大于1.0m/s时，用户的风感较强烈，需要降低室内风机31的转速，以降低风速。当用户所在位置的风速大于或等于0.3m/s且小于或等于1.0m/s时，用户体感有风，且风感较为适宜，室内风机31的转速只需保持当前的转速不变。
例如，为了保证用户所在处的风温适宜，通过公式1的逆函数R＝(Vρ,ρ)，取Vρ＝(0.3+1.0)/2＝0.65m/s，可计算出室内风机31所需调节的目标转速。
可以理解的是，当人体处于标准有效温度的环境中时，体感较为舒适。而当人体处于标准有效温度的环境中，且持续有风吹在人体上时，即使风温也为标准有效温度，人体也会感觉到微凉或者不适。
因此，为了达到人体在被室内机3的送风吹拂时，仍然保持舒适的效果，需要在标准有效温度的基础上，设定预设增量，标准有效温度与预设增量叠加后为修正温度。例如，用户体感舒适的环境温度为26℃，那么，将环境温度提升到27.5℃(即预设增量为1.5℃)，并持续向用户送风，有利于提高用户的舒适度，提高用户体验。
预设增量可以根据实际需求进行设置，本公开对此不作限定。例如，预设增量为0.1℃至6℃之间的任一值，例如，预设增量为0.1℃、0.5℃、1.0℃等。
需要说明的是，标准有效温度SET的定义为：身着标准服装(热阻0.6Clo)、代谢率为1met(相当于静止坐姿)的人处于相对湿度50％、空气近似静止、风速近似0.1m/s、空气温度与平均辐射温度相同的环境中，若此时的平均皮肤温度和皮肤湿度与某一实际环境和实际服装热阻条件下相同，则人体在标准环境和实际环境中会有相同的散热量，此时标准环境的空气温度就是实际所处环境的标准有效温度。
标准有效温度SET由4个环境因子(空气温度、相对湿度、空气风速和平均辐射温度)和2个人体因子(人体代谢率和服装热阻)决定，标准有效温度SET的计算公式为：
SET＝f(Tb,Va,Rh,Tr,M,Clo)                                (3)
其中，SET为标准有效温度，Tb为空气温度，Va为空气风速，Rh为相对湿度，Tr为平均辐射温度，M为人体代谢率，Clo为服装热阻。
若平均辐射温度等于空调器1检测的空气温度，相对湿度为空调器1检测的湿度，例如为50％；夏季服装热阻为0.6Clo，代谢率为1.0M。标准有效温度的计算公式可简化为：
SET＝f(Tb,Va)                                             (4)
计算机预先通过计算求解公式(3)，得出标准有效温度与空气温度的关系表，并将该表存入控制器7，控制器7通过调取该表获取某标准有效温度下对应的空气温度。
图7为根据一些实施例的一种空调器的控制器的又一种执行方法的流程图。在一些实施例中，如图7所示，控制器7还被配置为，当控制器7根据识别信号，判断室内机3的预设送风覆盖范围内存在人体时，控制器7还被配置为同步执行步骤S14和步骤S19。
在步骤S19中，根据预设增量修正预设的标准有效温度以得到修正温度，并根据预设的人体代谢率、服装热阻、相对湿度、平均辐射温度和所述修正温度，调整空调器1的空气温度。
可以理解的是，通过修正标准有效温度得到所述修正温度，控制器7根据所述修正温度对空调器1吹出的空气温度进行调节，在保证用户舒适性的同时，也降低了空调器1的能耗。例如，空调器1在制冷模式下，修正温度每升高1℃，能够使空调器1节能10％左右，修正温度每升高1.5℃，能够使空调器1节能15％左右。
在一些实施例中，如图3和图4所示，室内机3还包括壳体61、空气过滤器、以及导风机构。空气过滤器设置在壳体61的顶部。导风机构包括导风板64和摆叶组件63。导风板64被配置为调节室内机3在竖直方向上的送风角度(即图1所示的上下方向)。摆叶组件63被配置为调节室内机3在水平方向上的送风角度(即图1所示的左右方向)。
壳体61包括多个开口。所述多个开口沿室内机3的长度方向(即图1所示的左右方向)延伸，且沿室内机3的高度方向(即图1所示的上下方向)间隔开排列。所述多个开 口包括吸入口和出风口72。
吸入口位于壳体61的顶部。室内风机31的转动，带动吸入口附近的室内空气从吸入口进入壳体61内部的空气过滤器中，在被所述空气过滤器过滤后，进入室内换热器16与室内换热器16中的冷媒进行热交换，而后被输送至室内风机31。
出风口72位于壳体61的底部。出风口72通过位于室内风机31周侧的涡旋流路72B与壳体61的内部连接。从吸入口吸入的室内空气由室内换热器16进行热交换之后，通过涡旋流路72B从出风口72吹出至室内。涡旋流路72B包括流路下表面72A。流路下表面72A设置在室内风机31的一侧，且沿室内风机31的周向延伸。例如，如图3所示，流路下表面72A大致位于室内风机31的后侧，沿室内风机31的顺时针方向，流路下表面72A与室内风机31之间的距离增大。
如图3所示，室内风机31大致位于壳体61内的中部位置处。室内风机31沿室内机3的长度方向延伸，且呈圆筒状。室内风机31在壳体61中转动，使得室内空气从吸入口被吸入，并经由空气过滤器和室内换热器16后从出风口72被吹出至室内。
在一些实施例中，室内风机马达31A设置在壳体61中，且与室内风机31连接。室内风机马达31A被配置为驱动室内风机31转动。例如，室内风机31的转速由室内风机马达31A的转速决定，室内风机马达31A的转速越大，室内风机31的转速越大，从而从出风口72吹出的空气的量越多，即，出风口72出风的风速越大。
导风板64设置在出风口72中，且沿室内机的长度方向延伸。导风板64与壳体61转动连接。室内机3还包括导风板驱动马达，导风板驱动马达用于驱动导风板64绕固定的轴转动，以使出风口72出风的方向上下摆动。控制器7还被配置为控制导风板驱动马达。
摆叶组件63设置在壳体61的内部，且靠近出风口72，摆叶组件63包括多个竖直的挡板，多个挡板通过连接件连接，或相互独立。室内机3还包括摆叶组件驱动马达。摆叶组件驱动马达被配置为驱动多个挡板分别绕竖直延伸的多个轴同步转动。以使出风口72出风的方向左右摆动。摆叶组件63在目标送风角度范围内进行摆动。控制器7还被配置为驱动摆叶组件驱动马达。
通常情况下，人体长时间停留在恒温环境会导致其热应激能力下降，因此，通过空调器1将环境温度调控为在一定的区间内变化，可以锻炼人体的热调节系统，有利于促进用户的健康。
可以理解的是，通过室内机3的出风口72周期性地向用户吹风，可以实现用户所在位置处的环境温度在一定的区间内变化，且可以避免长时间直吹。也就是说，控制器7控制导风板64和摆叶组件63分别在其对应的目标送风角度范围内摆动，并且在不直吹人体的送风角度的停留时间大于在直吹人体的送风角度的停留时间，使得从室内机3的出风口72吹出的风周期性地吹到用户身上，实现用户周期性地体感有风和体感无风，从而避免用户长时间在体感有风或无风的环境下失去对冷热刺激的生理调节能力。
图8为根据一些实施例的一种空调器的控制器的又一种执行方法的流程图。
在一些实施例中，如图8所示，当控制器7根据识别信号，判断室内机3的预设送风覆盖范围内存在人体时，控制器7还被配置为同步执行步骤S14、步骤S19和步骤S20A，且在执行步骤S20A后，执行步骤S20B。
在步骤S20A，根据人体检测装置6的识别信号确定摆叶组件63对应的目标送风角度范围，并获取导风板64对应的目标送风角度范围。
例如，摆叶组件63对应的目标送风角度范围是根据人体检测装置6的识别信号确定的。摆叶组件63对应的目标送风角度范围包括避开人体(即不直吹人体)的送风方向和与人体相交(即直吹人体)的送风方向。
例如，导风板64对应的目标送风角度范围根据人体检测装置6的识别信号确定，或者，也可以是预先测试得到所述导风板64实现天井气流的角度(即，距离地面高度1.7m至2.0m范围内都无风的角度位置)，再根据该角度和所述导风板64可正常转动到的最大 角度或较大位置，确定所述导风板64对应的目标送风角度范围，以实现上下摆动的空调送风周期性吹到用户身上。
在步骤S20B，控制导风板64和摆叶组件63分别在其对应的目标送风角度范围内以预设模式摆动。
例如，在预设模式中，导风板64和摆叶组件63在避开人体的送风方向的停留时间大于在与人体相交的送风方向的停留时间。
在一些实施例中，控制器7还可以单独对导风机构进行控制，以使导风板64和摆叶组件63分别在其对应的目标送风角度范围内以预设模式摆动。
如图9A所示，控制器7还被配置为执行步骤S21至步骤S25。
在步骤S21，判断热应激舒适功能是否开启，若是，则执行步骤S22。
在步骤S22，获取人体检测装置6的识别信号。
在步骤S23，根据人体检测装置6的识别信号，判断室内机3的预设送风覆盖范围内是否存在人体，若是，则执行步骤S24。
例如，人体检测装置6被配置为识别人体方位，所述识别信号包括所述人体方位信息。
在步骤S24，根据识别信号确定摆叶组件63对应的目标送风角度范围，并获取导风板64对应的目标送风角度范围。
在步骤S25，控制导风板64和摆叶组件63分别在其对应的目标送风角度范围内以预设模式摆动。
在一些实施例中，如图9B所示，当控制器7根据人体检测装置6的识别信号，确定室内机3的预设送风覆盖范围内存在人体时，控制器7还被配置为同时执行步骤S24和步骤S26。
在步骤S26，根据预设增量修正预设的标准有效温度以得到修正温度，并根据预设的人体代谢率、服装热阻、相对湿度、平均辐射温度和所述修正温度，调整空调器1的目标运行参数。
图10A为根据一些实施例的一种空调器运行过程中用户处的标准有效温度变化周期图，图10B为根据一些实施例的一种空调器运行过程中用户处的风速变化周期图。
在一些实施例中，如图10A和图10B所示，导风板64和摆叶组件63从初始位置摆动到目标位置再回到初始位置为一个摆动周期T0。在一个摆动周期T0中，室内机3送风的角度随着导风板64和摆叶组件63的摆动而改变，室内机3的送风与人体相交的时间为第一预设时间T1，且避开人体的时间为第二预设时间T2。在第一预设时间T1内，用户体感有风且有凉感，而在第二预设时间T2内，用户体感无风或风感较为轻微(如风速小于0.2m/s)，且感到微热。例如，第一预设时间T1小于第二预设时间T2。
图11为根据一些实施例的一种空调器的摆叶组件在用户处于第一位置时的目标送风角度范围示意图。
在一些实施例中，如图11所示，摆叶组件63的预设送风覆盖范围(即室内机3在横向上的预设送风覆盖范围)为摆叶组件63的第一极限送风方向D1与摆叶组件63的第二极限送风方向D2所围成的区域(如扇形区域)。预设送风覆盖范围的中心线为中心线P(即中心线)，用户与摆叶组件63的连线与中心线P之间的夹角为相对角度β。例如，定义第一送风角度θmin为所述第一极限送风方向D1与中心线P之间的夹角，且第一送风角度θmin处于中心线P的顺时针方向。定义第二送风角度θmax为所述第二极限送风方向D2与中心线P之间的夹角，且第二送风角度θmax处于所述预设送风覆盖范围的中心线的逆时针方向。
摆叶组件63对应的目标送风角度范围为第一横向送风方向D3与第二横向送风方向D4所围成的区域(如扇形区域)。当摆叶组件63摆动至第一横向送风方向D3时，室内机3的送风直吹人体，当摆叶组件63摆动至第二横向送风方向D4时，室内机3的送风远离人体。
可以理解的是，第一横向送风方向D3与第二横向送风方向D4所围成的区域位于第一极限送风方向D1与第二极限送风方向D2所围成的区域中，也即，摆叶组件63对应的目标送风角度范围位于摆叶组件63的预设送风覆盖范围中。
第一横向送风方向D3与中心线P之间的夹角为第一横向角度H1，且第二横向送风方向D4与中心线P之间的夹角为第二横向角度H2。
第一横向送风方向D3为摆叶组件63的一个摆动周期中的初始送风方向，第二横向送风方向D4为摆叶组件63的一个摆动周期中的目标送风方向。也就是说，当摆叶组件63摆动至初始位置时，室内机3的横向送风方向与中心线P之间的夹角为第一横向角度H1。当摆叶组件63摆动至目标位置时，室内机3的横向送风方向与中心线P之间的夹角为第二横向角度H2。
在一些实施例中，当空调器1的热应激舒适功能开启，且室内机3的预设送风覆盖范围内存在人体时，需要确定摆叶组件63对应的目标送风角度范围。
如图11所示，当用户处于室内的第一位置，即，用户处于中心线P的顺时针方向(即，中心线P的右侧)时，确定第一横向角度H1大致等于相对角度β，第二横向角度H2的绝对值与第一横向角度H1的绝对值之和大致等于第一送风角度θmin的绝对值与第二送风角度θmax的绝对值之和的二分之一，且第二横向角度H2处于中心线P的逆时针方向(即，中心线P的左侧)。
图12为根据一些实施例的一种空调器的摆叶组件在用户处于第二位置时的目标送风角度范围示意图。
如图12所示，当用户处于第二位置，即用户处于中心线P的逆时针方向(即，中心线P的左侧)时，确定第一横向角度H1等于相对角度β，第二横向角度H2的绝对值与第一横向角度H1的绝对值之和大致等于第一送风角度θmin的绝对值与第二送风角度θmax的绝对值之和的二分之一，且第二横向角度H2处于中心线的顺时针方向(即，中心线P的右侧)。
结合摆叶组件63的预设送风覆盖范围和相对角度β，可以确定摆叶组件63对应的目标送风角度范围，从而有利于提高对室内机3的左右方向上的送风控制的准确性。
可以理解的是，当用户处于摆叶组件63的预设送风覆盖范围内的不同位置时，用户与室内机3之间的相对角度β不同，且摆叶组件63对应的第一横向角度H1也不同。
若以室内机3作为圆心，将中心线P(也即室内机3正前方)作为0°基准，则第一送风角度θmin小于0°，且第二送风角度θmax大于0°。摆叶组件63的预设送风覆盖范围小于检测装置6的检测区域，且位于检测装置6的检测区域中。
例如，检测装置6的第一极限检测方向D5与中心线P之间的夹角为δmax(如，δmax＞θmax＞0°)，且检测装置6的第二极限检测方向D6与中心线P之间的夹角为δmin(如，δmin＜θmin＜0°)。检测装置6的检测区域为第一极限检测方向D5与第二极限检测方向D6限定出的区域(如扇形区域)。第一送风角度θmin的绝对值与第二送风角度θmax的绝对值之和的二分之一为θ1。
参见图11，在用户位于中心线P的右侧(即顺时针方向的一侧)的情况下，摆叶组件63摆动至初始位置时，室内机3的横向送风方向位于中心线P的顺时针方向(即θmin≤β＜0°)，摆叶组件63摆动至目标位置时，室内机3的横向送风方向位于中心线P的逆时针方向，那么，摆叶组件63从初始位置逆时针转动θ1到达目标位置后，再从目标位置顺时针转动θ1回到初始位置的过程为摆叶组件63的一个摆动周期。
参见图12，在用户位于中心线P的左侧(即逆时针方向的一侧)的情况下，摆叶组件63摆动至初始位置时，室内机3的横向送风方向位于中心线P的逆时针方向(即θmax≥β＞0°)，摆叶组件63摆动至目标位置时，室内机3的横向送风方向位于中心线P的顺时针方向，那么，摆叶组件63从初始位置顺时针转动θ1到达目标位置后，再从目标位置逆时针转动θ1回到初始位置的过程为摆叶组件63的一个摆动周期。
图13为根据一些实施例的一种空调器的摆叶组件在用户处于第三位置时的目标送风角度范围示意图。图14为根据一些实施例的一种空调器的摆叶组件在用户处于第四位置时的目标送风角度范围示意图。
参见图13和图14，当用户处于第三位置和第四位置时，即当用户位于检测装置6的检测区域内，且位于摆叶组件63对应的目标送风角度范围外时，受到摆叶组件63摆动极限的限制，第一横向角度H1等于第一送风角度θmin，且第二横向角度H2为0°，或者，第一横向角度H1等于第二送风角度θmax，且第一横向角度H1为0°。在一些实施例中，第一送风角度θmin的绝对值等于第二送风角度θmax，即，-θmin＝θ1＝θmax。
图19为根据一些实施例的一种空调器的导风板摆动至不同角度时的剖面图。如图19所示，导风板64可转动至第一纵向位置L1、第二纵向位置L2和纵向极限位置L3。当导风板64转动至第一纵向位置L1时，导风板64的第一纵向送风方向Z1与人体相交，当导风板64转动至第二纵向位置L2时，导风板64的第二纵向送风方向Z2避开人体。纵向极限位置L3是导风板64可以向下转动的极限位置。导风板64对应的目标送风角度范围为第一纵向位置L1至第二纵向位置L2之间的夹角α(如α大于等于0°)。第一纵向位置L1与纵向极限位置L3之间的夹角为第一纵向角度，第二纵向位置L2与纵向极限位置L3之间的夹角为第二纵向角度。
在一些实施例中，步骤S20B(或步骤S25)包括：控制导风板64在第一纵向位置L1停留第一预设时间T1后，摆动到第二纵向位置L2并从第二纵向位置L2摆动回第一纵向位置L1达到第二预设时间T2；同步控制摆叶组件63在第一横向送风方向D3停留第一预设时间T1后，摆动至第二横向送风方向D4再摆动回第一横向送风方向D3达到第二预设时间T2。
图15为根据一些实施例的一种空调器的导风板摆动至第一纵向位置时，室内机的送风流向图，图16为根据一些实施例的一种空调器的摆叶组件摆动至第一横向送风方向D3时，室内机的送风流向图。
如图15和图16所示，第一纵向位置作为导风板64的起始位置，第一横向送风方向D3作为摆叶组件63摆动的起始送风方向。控制器7控制导风板64转动到第一纵向位置停留第一预设时间T1，并同步控制摆叶组件63转动到第一横向送风方向D3停留第一预设时间T1。
图17为根据一些实施例的一种空调器的导风板摆动至第二纵向位置时，室内机的送风流向图，图18为根据一些实施例的一种空调器的摆叶组件摆动至第二横向送风方向D4时，室内机的送风流向图。
如图17和图18所示，当导风板64在第一纵向位置L1停留第一预设时间T1时，导风板64从第一纵向位置L1以第一角速度顺时针转动到第二纵向位置，再以第一角速度逆时针转动到第一纵向位置，达到第二预设时间T2。
与导风板64同步，当摆叶组件63在第一横向角度H1停留第一预设时间T1时，摆叶组件63从第一横向角度H1以第二角速度逆时针或顺时针转动到第二横向角度H2后再以第二角速度顺时针或逆时针转动回到第一横向角度H1，达到第二预设时间T2。
在一些实施例中，当人体检测装置6检测到人体所在的位置发生改变，则当一个摆动周期T0结束时(即，当导风板64以第一角速度逆时针转动到第一纵向位置L1时，或者，当摆叶组件63以第二角速度顺时针或逆时针转动回到第一横向角度H1时)，控制器7根据用户与出风口72之间的距离和相对角度以及室内风机31的当前转速，再次确定导风板64的第一纵向位置、第二纵向位置L2和第一角速度，摆叶组件63的第一横向角度H1、第二横向角度H2和第二角速度，以及室内风机31转速。
在一些实施例中，当人体检测装置6检测不到用户时(即，用户位于人体检测装置6的检测范围之外)，控制器7还被配置为控制空调器1调节室内空气温度为预设的标准有效温度，并控制导风板64的摆动角度、摆叶组件63的摆动角度以及室内风机31的转速 维持不变。
图20为导风板64、摆叶组件63按照预设的组合动作时序，仿照自然风的无序风速，实测的风速频谱。可以理解的是，摆动周期T0、第一预设时间T1和第二预设时间T2可以根据实际需求进行设置，在此不作限定。在一些实施例中，摆动周期T0和第一预设时间T1的比值范围为2至20。例如，摆动周期T0和第一预设时间T1的比值为2、5、8、等。
需要说明的是，导风板64和摆叶组件63的可以有多种动作组合时序、动作周期，形成的气流按照频谱，可以为仿自然风、机械风等，起始角度对应的气流也可为无风或微风，本公开对此不作限定。然而，无论导风板64和摆叶组件63以何种动作周期、何种气流、何种周期起点运动，只要形成的气流周期性地使用户体感有风和体感无风，再结合微热的环境温度，即可实现热应激舒适功能，均应在本公开的保护范围内。
在一些实施例中，空调器1包括落地式的室内机3，导风机构包括导风板64和摆叶组件63，控制器7被配置为控制导风板64和摆叶组件63的动作时序，从而实现热应激舒适功能。
空调器1的设定参数包括：SET＝26℃，△t＝1.5℃，T0＝60s，T1＝6s，T2＝54s，K1＝0.0017m/(rpm*s)，K2＝0.58m/s，K3＝0.0033m/rpm，K4＝1.3m，θmax＝60°，θmin＝-60°，δmax＝75°，δmin＝-75°，R＝900rpm。导风板64的第一纵向角度为24°，第二纵向角度为90°，导风板64的第一纵向位置L1与第二纵向位置L2之间的夹角为64°。预设风速下限为0.3m/s，预设风速上限为1.0m/s。
第一角速度ω1等于第一纵向位置L1与第二纵向位置L2之间的角度α的两倍与第一预设时间T1的比值；第一角速度ω1满足如下公式：
ω1＝2α/T1                                                   (5)
第二角速度ω2等于第一横向送风方向D3和第二横向送风方向D4之间夹角的角度(即θ1)的两倍与第一预设时间T1的比值。第二角速度ω2满足如下公式：
ω2＝2θ1/T1                                                  (6)
用户开启热应激舒适功能时，若人体检测装置6检测到人体所在位置对应的信息包括用户与室内机3的距离ρ＝2.0m，以及用户与室内机3之间的相对角度β＝-15°，则控制器7被配置为执行步骤S101至步骤S103。
在步骤S101，通过预设增量△t和标准有效温度SET计算修正后的标准有效温度(即△t+SET)，并将空气温度调节至27.5℃(26℃+1.5℃)。
在步骤S102，控制导风板64转动到第一纵向角度(24°)，并停留6s(即，第一预设时间T1)，同步地，控制摆叶组件63转动到第一横向角度H1(-15°)，并停留6s(即，第一预设时间T1)。
在步骤S103，控制导风板64以2α/T2＝2*(90°-24°)/6＝22°/s的角速度顺时针转动到第二纵向角度(90°)，再以22°/s的角速度逆时针转回到第一纵向角度(24°)，同步地，控制摆叶组件63以2θ1/T2＝2*60/6＝20°/s的角速度逆时针转动到第二横向角度H2(45°)，再顺时针转回到第一横向角度H1(-15°)，这一过程用时54s(即，第二预设时间T2)；以及，控制室内风机31的转速降低至830rpm。
可以理解的是，当用户所在位置没有发生改变时，若控制器7计算出用户当前所在位置的风速为1.0m/s∈[0.3m/s,1.0m/s]，则控制室内风机31的转速不变。
当用户所在位置发生改变时，例如，人体检测装置6检测到人体与室内机3之间的距离为3.0m，用户与摆叶组件63的预设送风覆盖范围的中心线之间的夹角为20°，则导风板64的第一纵向位置与任一水平面之间的夹角为90°，摆叶组件63的第一横向角度H1为20°，在此情况下，若控制器7计算出用户当前所在位置的风速为0.5m/s∈[0.3m/s,1.0m/s]，则室内风机31维持当前转速不变。室内机3直吹用户所在位置处6s后，导风板64以22°/s的角速度先顺时针转到24°，再逆时针转回到90°的初始位置，同步地，摆叶组件63以20°/s 的角速度先顺时针转到-40°，再逆时针转回到20°的初始位置，这一过程用时54s。
图21A为根据一些实施例的另一种空调器的一种目标送风角度范围的示意图(用户处于第一送风区域)。
在一些实施例中，如图21A所示，摆叶组件63的预设送风覆盖范围包括多个目标区域。例如，所述多个目标区域包括第一送风区域R1、第二送风区域R2、第三送风区域R3、第四送风区域R4和第五送风区域R5。第一送风区域R1至第五送风区域R5沿逆时针方向排列，分别呈扇形，且共用圆心。在第一送风区域R1至第五送风区域R5中，每个目标区域对应的摆叶组件63送风角度相同，例如，每个目标区域对应的摆叶组件63的送风角度为2θ1/5(即，(θmax-θmin)/5)。在第一送风角度θmin的绝对值等于第二送风角度θmax的情况下，2θ1/5＝2θmax＝-2θmin。
在此情况下，在确定摆叶组件63对应的目标送风角度范围时，控制器7还被配置为根据人体检测装置6的识别信号，确定人体所在的目标区域，并根据所述多个目标区域的总数、摆叶组件63的第一极限送风方向D1和第二极限送风方向D2以及人体所在的目标区域，确定摆叶组件63对应的目标送风角度范围。
可以理解的是，为了便于摆叶组件63对应的目标送风角度范围的计算，将人体检测装置6所能检测的区域和摆叶组件63的预设送风覆盖范围近似看作重合。例如，将每个目标区域的中心线作为摆叶组件63的起始位置，该起始位置与中心线P之间的夹角为第一横向角度H1。
也就是说，当人体检测装置6检测到用户位于第一送风区域R1时，则第一送风区域R1的中心线作为摆叶组件63的起始位置；当人体检测装置6检测到用户在第三送风区域R3时，则第三送风区域R3的中心线作为摆叶组件63的起始位置，第三送风区域R3的中心线对应的第一横向角度H1为0°(即，第三送风区域R3的中心线与中心线P共线)。摆叶组件63从第一横向角度H1沿顺时针或逆时针方向，摆动达到第二横向角度H2的位置后再摆动回到第一横向角度H1，该过程为一个摆动周期。
例如，当用户所在位置处在第一送风区域R1中时，第一横向角度H1大致等于(-4)/5，第二横向角度H2大致等于θ1/5，摆叶组件63从第一横向角度H1逆时针转动至第二横向角度H2后再顺时针转回到第一横向角度H1。
图21B为根据一些实施例的另一种空调器的另一种目标送风角度范围的示意图(用户处于第二送风区域)。如图21B所示，当用户所在位置处于第二送风区域时，第一横向角度H1大致等于(-2θ1)/5，第二横向角度H2大致等于3θ1/5，摆叶组件63从第一横向角度H1逆时针转动至第二横向角度H2后再顺时针转回到第一横向角度H1。
图21C为根据一些实施例的另一种空调器的又一种目标送风角度范围的示意图(用户处于第三送风区域)。图21D为根据一些实施例的另一种空调器的又一种目标送风角度范围的示意图(用户处于第三送风区域)。如图21C和图21D所示，当用户所在位置处于第三送风区域时，第一横向角度H1大致等于0°，第二横向角度H2大致等于θmax或θmin，若第二横向角度H2大致等于θmax，摆叶组件63从第一横向角度H1逆时针转动至第二横向角度H2后再顺时针转回到第一横向角度H1；若第二横向角度H2大致等于θmin，摆叶组件63从第一横向角度H1顺时针转动至第二横向角度H2后再逆时针转回到第一横向角度H1。
图21E为根据一些实施例的另一种空调器的又一种目标送风角度范围的示意图(用户处于第四送风区域)。如图21E所示，当用户所在位置处于第四送风区域时，第一横向角度H1大致等于2θ1/5，第二横向角度H2大致等于(-3θ1)/5，摆叶组件63从第一横向角度H1顺时针转动到第二横向角度H2后再逆时针转回到第一横向角度H1。
图21F为根据一些实施例的另一种空调器的又一种目标送风角度范围的示意图(用户处于第五送风区域)。如图21F所示，当用户所在位置处于第五送风区域时，第一横向角度H1大致等于4θ1/5，第二横向角度H2大致等于(-θ1)/5，摆叶组件63从第一横向角度H1 顺时针转动到第二横向角度H2后再逆时针转回到第一横向角度H1。
如此一来，当摆叶组件63的起始位置分别位于第一送风区域R1至第五送风区域R5，则摆叶组件63的第一横向角度H1、第二横向角度H2以及从起始位置到目标位置的转动方向详见表2。
表2摆叶组件63的第一横向角度H1、第二横向角度H2以及从起始位置到目标位置的转动方向
在一些实施例中，空调器1包括落地式的室内机3，导风机构包括导风板64和摆叶组件63，控制器7被配置为控制导风板64和摆叶组件63的动作时序，从而实现热应激舒适功能。
空调器1的设定参数包括：SET＝26℃，△t＝1.5℃，T0＝60s，T1＝6s，T2＝54s，θmax＝60°，θmin＝-60°，δmax＝60°，δmin＝-60°，导风板64的第一纵向角度为24°，导风板64的第二纵向角度为90°，导风板64的第一纵向位置L1与第二纵向位置L2之间的夹角为64°。预设风速下限为0.3m/s，预设风速上限为1.0m/s。
第一角速度ω1与第二角速度ω2的计算方式与前述实施例相同，此处不再赘述。
图22为根据一些实施例的另一种空调器的导风板摆动至第一纵向位置L1时，室内机的送风流向图，图23为根据一些实施例的另一种空调器的摆叶组件摆动至第一横向送风方向D3时，室内机的送风流向图，图24为根据一些实施例的另一种空调器的导风板摆动至第二纵向位置L2时，室内机的送风流向图，图25为根据一些实施例的另一种空调器的摆叶组件摆动至第二横向送风方向D4时，室内机的送风流向图。
当用户开启热应激舒适功能时，若人体检测装置6检测到人体位于第一送风区域R1,则控制器7被配置为执行步骤S201至步骤S203。
在步骤S201，通过预设增量△t和标准有效温度SET计算修正后的标准有效温度(即△t+SET)，并将空气温度调节至27.5℃(26℃+1.5℃)。
在步骤S202，如图22和图23所示，控制导风板64转动到第一纵向角度(24°)，并停留6s(即，第一预设时间T1)，同步地，控制摆叶组件63转到第一横向角度H1(-48°)，并停留6s(即，第一预设时间T1)。
例如，当用户所在位置位于第一送风区域R1，第一横向角度H1大致等于(-4θ1)/5，且θ1＝θmax＝60°，因此，第一横向角度H1为60°*(-4/5)＝-48°。
在步骤S203，如图24和图25所示，控制导风板64以2α/T2＝2*(90°-24°)/6＝22°/s的角速度顺时针转动至第二纵向角度(90°)，再以22°/s的角速度逆时针转回到第一纵向角度(24°)，同步地，控制摆叶组件63以2θ1/T2＝2*60/6＝20°/s的速度逆时针转动到第二横向角度H2(12°)，再以20°/s的角速度逆时针转回到第一横向角度H1(-48°)，这一过程用时54s(即，第二预设时间T2)。
例如，当用户所在位置位于第一送风区域R1，第二横向角度H2大致等于θ1/5，且θ1＝θmax＝60°，因此，第一横向角度H1为60°*1/5＝12°。
在一些实施例中，在步骤S13中，控制器7还被配置为若室内机3的预设送风覆盖范围内不存在人体时，控制导风板64和摆叶组件63不转动，且控制室内风机31的转速保持不变。
由于用户处于人体检测装置6的检测盲区或室内无人，即便改变气流方向和室内风机3的转速，与不能实现热应激功能，因此，在这种情况下，控制器7控制标准有效温度保 持预设值，并控制导风板64和摆叶组件63的转动角度保持上一状态不变，从而有效节能。
基于上述空调器1，如图5所示，本公开的一些实施例还提供了一种空调器的舒适控制方法，该方法由控制器7执行，且包括步骤S1至步骤S6。
在步骤S1，判断热应激舒适功能是否开启，若是，则执行步骤S2，若否，则重新执行S1。
在步骤S2，获取人体检测装置6的识别信号和室内风机31的当前转速。
例如，当控制器7判断空调器1的热应激舒适功能开启时，人体检测装置6实时检测人体与室内机3的出风口72之间的距离和相对角度，并将代表所述距离和所述相对角度的识别信号发送至控制器。
在步骤S3，根据该识别信号，判断室内机3的预设送风覆盖范围内是否存在人体，若是，则执行步骤S4。
在步骤S4，根据人体与室内机3之间的距离和室内风机31的当前转速，计算用户所在位置处的风速。
在步骤S5，判断用户所在位置处的风速与预设风速上限值之间的大小关系，若用户所在位置处的风速高于所述预设风速上限值，则执行步骤S6。
在步骤S6，控制室内风机31降低转速。
例如，控制器7控制室内风机31降低转速，以使用户所在位置处的风速小于所述预设风速上限值，且大于所述预设风速下限值。
在一些实施例中，如图6所示，在步骤4之后，该方法还包括步骤S5’以及步骤S6至步骤S8。
在步骤S5’，判断用户所在位置处的风速与所述预设风速上限值和所述预设风速下限值之间的大小关系，若用户所在位置处的风速高于所述预设风速上限值，则执行步骤S6；若用户所在位置处的风速低于所述预设风速下限值，则执行步骤S7；若用户所在位置处的风速处于所述预设风速下限值和所述预设风速上限值之间，则执行步骤S8。
在步骤S6，控制室内风机31降低转速。
在步骤S7，控制室内风机31提高转速。
例如，控制器7控制室内风机31提高转速，以使用户所在位置处的风速小于所述预设风速上限值，且大于所述预设风速下限值。
需要说明的是，当风速过低时，用户所感受到的风感较轻微，无法明显感受到温度的变化。因此，若风速过低，则控制室内风机31提高转速，以避免因风速过低而导致人体感受的体感温度过低，从而有效提高舒适性。
预设风速下限值可以根据实际舒适性需求进行设置，在此不做限定。例如，预设风速下限值为0.3至0.5m/s之间的任一值。例如，预设风速下限值为0.3m/s、0.4m/s、0.5m/s。
在步骤S8，控制室内风机31维持当前转速。
可以理解的是，若用户所在位置处的风速处于所述预设风速下限值和所述预设风速上限值之间，则表面风速适中，在此情况下，控制室内风机31转速不变，使人体感受的体感温度保持在合适水平，可以有效提高用户的舒适度。
在一些实施例中，如图7所示，当根据识别信号，判断室内机3的预设送风覆盖范围内存在人体时，该方法还包括步骤S9，步骤S9与步骤S4同步执行。
在步骤S9中，根据预设增量修正预设的标准有效温度以得到修正温度，并根据预设的人体代谢率、服装热阻、相对湿度、平均辐射温度和所述修正温度，调整空调器1的空气温度。
可以理解的是，通过修正标准有效温度得到所述修正温度，控制器7根据所述修正温度对空调器1吹出的空气温度进行调节，在保证用户舒适性的同时，也降低了空调器1的能耗。例如，空调器1在制冷模式下，修正温度每升高1℃，能够使空调器1节能10％左右，修正温度每升高1.5℃，能够使空调器1节能15％左右。
在一些实施例中，如图8所示，当根据识别信号，判断室内机3的预设送风覆盖范围内存在人体时，该方法还包括步骤S10A和S10B，步骤S10A与步骤S4和步骤S9同步执行，且在执行步骤S10A后，执行步骤S10B。
在步骤S10A，根据人体检测装置6的识别信号确定摆叶组件63对应的目标送风角度范围，并获取导风板64对应的目标送风角度范围。
例如，摆叶组件63对应的目标送风角度范围是根据人体检测装置6的识别信号确定的。摆叶组件63对应的目标送风角度范围包括避开人体(即不直吹人体)的送风方向和与人体相交(即直吹人体)的送风方向。
例如，导风板64对应的目标送风角度范围根据人体检测装置6的识别信号确定，或者，也可以是预先测试得到所述导风板64实现天井气流的角度(即，距离地面高度1.7m至2.0m范围内都无风的角度位置)，再根据该角度和所述导风板64可正常转动到的最大角度或较大位置，确定所述导风板64对应的目标送风角度范围，以实现上下摆动的空调送风周期性吹到用户身上。
在步骤S10B，制导风板64和摆叶组件63分别在其对应的目标送风角度范围内以预设模式摆动。
例如，在预设模式中，导风板64和摆叶组件63在避开人体的送风角度的停留时间大于在与人体相交的送风角度的停留时间。
基于上述空调器1，如图9A所示，本公开的一些实施例还提供了另一种空调器的舒适控制方法，该方法由控制器7执行，且包括步骤S21’至步骤S25’。
在步骤S21’，判断热应激舒适功能是否开启，若是，则执行步骤S22’。
在步骤S22’，获取人体检测装置6的识别信号。
在步骤S23’，根据人体检测装置6的识别信号，判断室内机3的预设送风覆盖范围内是否存在人体，若是，则执行步骤S24’。
在步骤S24’，根据识别信号确定摆叶组件63对应的目标送风角度范围，并获取导风板64对应的目标送风角度范围。
在步骤S25’，控制导风板64和摆叶组件63分别在其对应的目标送风角度范围内以预设模式摆动。
在一些实施例中，如图9B所示，当根据人体检测装置6的识别信号，确定室内机3的预设送风覆盖范围内存在人体时，该方法还包括步骤S26’，步骤S26’与步骤S24’同步执行。
在步骤S26’，根据预设增量修正预设的标准有效温度以得到修正温度，并根据预设的人体代谢率、服装热阻、相对湿度、平均辐射温度和所述修正温度，调整空调器1的目标运行参数。
