本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
图1是根据一些实施例的一种空调器的结构图，图2是根据一些实施例的一种空调器框图。如图1和图2所示，本公开一些实施例提供一种空调器10，空调器10包括室外机20、室内机30、温度传感器50、风速传感器60、测距传感器70和膨胀阀80。空调器10的室外机20包括压缩机21、室外换热器22和室外风扇23，空调器10的室内机30包括室内换热器31、室内风扇32、气流控制机构33和室内出风口34。室外机20或室内机30中的至少一个设置有膨胀阀80。压缩机21、冷凝器(室内换热器31或室外换热器22)、膨胀阀80和蒸发器(室外换热器22或室内换热器31)来执行空调器10的冷媒循环。冷媒循环包括一系列过程，涉及压缩、冷凝、膨胀和蒸发，并向被调节侧循环供应冷媒。
压缩机21压缩处于低温低压状态的气相冷媒并排出压缩后的高温高压的气相冷媒，高温高压的气相冷媒流入冷凝器。冷凝器将高温高压的气相冷媒冷凝成高压状态的液相冷媒，热量随着冷凝过程释放到周围环境。膨胀阀80将高压状态的液相冷媒膨胀为低压状态的气液两相态冷媒。蒸发器从周围环境中吸取热量并将低压状态的气液两相态冷媒蒸发形成低温低压的气相冷媒，低温低压状态的气相冷媒返回到压缩机21中。
室内换热器31被配置为通过将室内空气与在室内换热器31中传输的冷媒进行热交换对冷媒进行液化或汽化中的一种。室外换热器22被配置为通过将室外空气与在室外换热器22中传输的冷媒进行热交换对冷媒进行液化或汽化中的另一种。例如，室内换热器31在空调器10运行在制冷模式时作为蒸发器进行工作，使得经由室外换热器22散热后的冷媒通过室内换热器31吸收室内空气的热量而蒸发。室内换热器31在空调器10的制热模式下作为冷凝器进行工作，使得经由室外换热器22吸热后的冷媒通过室内换热器31将热量散发至室内空气而冷凝。
气流控制机构33被配置为控制室内机30的出风气流的方向。需要说明的是，本公开一些实施例中的气流控制机构33包括但不限于横向导风板或纵向导风板中的至少一个。
温度传感器50包括室外温度传感器51和室内温度传感器52。室内温度传感器52包括室内环境温度传感器521、出风温度传感器522和盘管温度传感器523。室内环境温度传感器521设置在室内机30内，被配置为检测实际的室内空气温度。出风温度传感器522设置在室内出风口34处，被配置为检测室内机30的出风温度。盘管温度传感器523被配置为检测室内盘管处的温度。
风速传感器60设置在室内出风口34处，被配置为检测室内机30的出风风速。
测距传感器70设置在室内机30内，被配置为检测用户所处位置与室内出风口34之间的距离(即用户距离)。在本公开一些实施例中，测距传感器70还用于检测用户所处位置与室内出风口34之间的角度θ。需要说明的是，测距传感器70包括但不限于毫米波雷达传感器或红外传感器。
膨胀阀80可以是电子膨胀阀，连接于室外换热器22与室内换热器31之间。电子膨胀阀80包括室外电子膨胀阀81和室内电子膨胀阀82。由电子膨胀阀80的开度大小调节流经室外换热器22和室内换热器31的冷媒压力，以调节流通于室外换热器22和室内换热器31之间的冷媒流量。流通于室外换热器22和室内换热器31之间的冷媒的流量和压力将影响室外换热器22和室内换热器31的换热性能。
室外风扇23被配置为促进在室外换热器22的传热管中流动的冷媒与室外空气的热交换。室内风扇32被配置为促进室内换热器31的传热管中流动的冷媒与室内空气的热交换，以辅助温度调节。
在本公开一些实施例中，空调器10还包括控制器40，控制器40与室外机20、室内机30、温度传感器50、风速传感器60、测距传感器70、以及膨胀阀80耦接，控制器40被配置为控制与该控制器40耦接的各部件的工作状态。控制器40可以划分为室内控制器和室外控制器，分别用于对室内机30和室外机20的结构部件进行控制。
控制器40可以包括中央处理器(central processing unit,CPU)、微处理器(microprocessor)、专用集成电路(application specific integrated circuit,ASIC)，并且可以被配置为当处理器执行存储在耦合到控制器40的非暂时性计算机可读介质中的程序时，执行控制器40中描述的相应操作。
相关技术中，空调器10通常以风温作为单一的控制目标，通过对压缩机21的运行频率进行调整，来改变空调器10的制冷能力和出风温度，满足用户所需的室内空气温度。然而，空调器10的出风风速大小对室内空气温度的均匀性的影响更大，且人体的实际感受为风温和风速耦合后的结果，并不是单一风温产生的感受，例如，空调器10的出风温度一定时，风速越大，人体的体感温度越低。因此，若仅以风温作为控制目标，且不考虑用户体感的标准有效温度与用户距离的变化，难以满足用户对体感舒适温度的要求。
为了解决上述技术问题，本公开一些实施例提供一种空调器的控制方法，应用到控制器40上。本公开一些实施例的空调器10的控制方法，引入了标准环境温度的概念，通过考虑风速和风温两个影响因素来实现对压缩机21的运行频率的控制，并通过测距传感器70实时检测用户所处位置与室内出风口34之间的用户距离，控制室内机30的出风气流吹向用户所处位置，使得对空调器10的运行频率的调整更加精准有效，用户设定测点或用户所在位置的温度能够尽快达到用户所需的温度。
图3为根据一些实施例的一种空调器的控制方法的流程图，如图3所示，在本公开一些实施例中，该控制方法包括步骤S1至步骤S5。
步骤S1，获取当前设定的标准有效温度范围和用户距离，并检测出风温度和出风风速。
用户距离ρ由测距传感器70检测得到。图5是根据一些实施例的室内机出风方向的一种示意图，如图5所示，用户所处位置为室内机30的出风气流带中心位置，用户所处位置与室内出风口34之间的距离为用户距离ρ。
需要说明的是，标准有效温度(standard effective temperature，SET)的定义为：身着标准服装(热阻0.6clo)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、代谢率为1met(相当于人处于静止坐姿)的环境中，若此时人体的平均皮肤温度和皮肤湿度与一个实际环境和实际服装热阻条件相同，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SET，通常需要整个房间内所有区域或大部分区域都能达到舒适的标准有效温度SET。
上述单位clo为克洛，是航空医学测量绝热的单位。MET(metabolic equivalent of energy)指能量代谢当量，音译为梅脱，是以安静、坐位时的能量消耗为基础，表达各种活动时相对能量代谢水平的常用指标。
标准有效温度SET由4个环境因子(回风温度Ta、相对湿度Rh、风速Va、平均辐射温度Tr)和2个人体因子(人体代谢率M、服装热阻clo)参与计算，即存在关于SET＝f(Ta，Va，Rh，Tr，M，clo)的函数或计算程序。假设平均辐射温度Tr＝回风温度Ta，相对湿度Rh为空调器10检测的湿度，空调器10运行在制冷模式时，室内空气经过蒸发器后，湿度已经下降，此时空调器10吹出的空气的相对湿度Rh通常在40％～70％之间，默认为50％。夏季服装热阻0.6clo，代谢率为1.0M。如此，可以将SET＝f(Ta，Va，Rh，Tr，M，clo)计算程序，简化为通过回风温度Ta和风速Va，求解标准有效温度SET，即SET＝f(Ta，Va)的函数。相应的，也可以得到Ta＝f(SET，Va)和Va＝f(Ta，SET)的函数。
在本公开一些实施例中，用户可以根据自身的需求，设定当前的目标标准有效温度SETs，并根据目标标准有效温度SETs来确定标准有效温度范围。标准有效温度范围为[SETs-ΔT，SETs+ΔT]。其中，ΔT为温度常数，且ΔT>0。ΔT的值可以根据实际需求进行设定。
在本公开一些实施例中，ΔT的取值范围为0.1℃≤ΔT≤5℃。例如，ΔT＝1℃时，用户希望吹到自己身上的目标标准有效温度SETs趋近于25℃，则可以设置标准有效温度范围为[24.0℃,26.0℃]。
回风温度Ta为实际的室内空气温度，由室内环境温度传感器521检测得到。
出风温度T_out可以通过出风温度传感器522检测得到。当然，出风温度T_out还可以通过公式1计算得到。
T_out＝K1×Te       公式1
其中，Te为室内盘管温度，通过设置在室内盘管处的盘管温度传感器523测得，K1为温度常数，根据多次测试或经验得到。
出风风速Va_out可以通过风速传感器60检测得到。当然，出风风速Va_out还可以通过公式2计算得到。
Va_out＝K2×R       公式2
其中，K2为风速系数，R为室内风扇32的转速。
步骤S2，根据回风温度Ta、出风温度T_out、出风风速Va_out和用户距离ρ，计算实时标准有效温度SETρ。
实时标准有效温度SETρ为室内出风口34与用户所处位置之间的距离为用户距离ρ的出风气流带中心的标准有效温度。
步骤S3，判断实时标准有效温度SETρ是否处于标准有效温度范围[SETs-ΔT，SETs+ΔT]外，若是，则执行步骤S4，若否，则执行步骤S5。
步骤S4，确定温度差值与温度阈值的大小关系，并根据结果调整压缩机21的运行频率F和室内风扇32的转速R。
在本公开一些实施例中，E1为预设的温度阈值。
步骤S5，维持压缩机21的运行频率F和室内风扇32的转速R不变。
当空调器10运行在制冷模式时，随着用户所处位置与室内出风口34之间的用户距离的增加，风温上升，风速下降，人体感受到的温度随之上升；反之，随着用户距离的减小，风温下降，风速上升，人体感受到的温度随之下降，即用户体感的温度随用户距离的变化而变化。
为了解决上述问题，在本公开一些实施例的控制方法中，控制器40通过控制气流控制机构33，使室内机30的出风气流可以实时的吹向用户所处位置，以满足用户对空调器10的出风舒适性的要求，更好地为用户提供舒适的空调环境。
图4是根据一些实施例的另一种空调器的控制方法的流程图，如图4所示，在本公开一些实施例中，测距传感器70还被配置为检测用户所处位置与室内出风口34之间的角度θ，此时，空调器10的控制方法还包括步骤S100至步骤S101。
步骤S100，由测距传感器70测出用户距离ρ以及用户所处位置与室内出风口34之间的角度θ。
需要说明的是，用户所处位置与室内出风口34之间的角度θ，是指用户所处位置与在与室内出风口34等高的水平面上，垂直于室内机30的长度方向的出风气流方向，之间的夹角。
图6是根据一些实施例的室内机出风方向的另一种示意图，如图6所示，以垂直于室内机30的长度方向的出风气流方向为0°基准，出风气流向顺时针方向(图6中A方向)偏转的角度θ为负数，出风气流向逆时针方向(图6中B方向)偏转的角度θ为正数。
步骤S101，根据用户距离ρ和用户所处位置与室内出风口34之间的角度θ，控制气流控制机构33运动，使室内机30的出风气流吹向用户所处位置。
测距传感器70通过用户距离ρ和用户所处位置与室内出风口34之间的角度θ，实时检测并精确定位用户所处位置与室内出风口34的相对位置关系。控制器40获取用户距离ρ和偏转的角度θ，并通过用户距离ρ和偏转的角度θ，控制气流控制机构33运动，使室内机30的出风气流吹向用户所处位置，以保持用户所处位置位于室内机30的出风气流带中心，满足用户对空调器10的定向出风的要求，即在控制风温和风速的同时实现风吹人功能。
在本公开一些实施例中，当用户所处位置发生改变时，控制器40通过测距传感器70获取改变后的用户距离ρ和偏转的角度θ，且在用户位于改变后的位置T1秒后，控制器40控制气流控制机构33运动，使室内机30的出风气流吹向改变后的用户所处位置。T1例如为30s。
图7是根据一些实施例的又一种空调器的控制方法的流程图，如图7所示，在本公开一些实施例中，步骤S2包括步骤S21至步骤S23。
步骤S21，获取当前设定的室内风扇32的转速R，并根据该转速R，计算当前的目标送风距离。
在本公开一些实施例中，空调器10的目标送风距离可以为最远送风距离ρmax，与当前设定的室内风扇32的转速R有关，通常，室内风扇32的转速R越大，目标送风距离ρmax越大。
图8是根据一些实施例的空调器的出风气流带中心风速与距离的关系图，其中，室内风扇32的转速R、送风距离和风速的对应关系如表1所示。
表1室内风扇的转速、送风距离和风速的对应关系
表1为某1.5匹空调器10的室内风扇的转速、送风距离和风速的对应关系表。表1中首行为出风气流带中心与室内出风口34之间的距离，即送风距离，单位为m；右侧第一列为目标送风距离，单位为m；左侧第一列为室内风扇32的转速R，可以用室内风扇32的档位表征；表中的值为出风气流中心带的风速Va，单位为m/s。根据表1，将室内风扇32的转速R与目标送风距离ρmax线性拟合为一次函数，例如为公式3，并根据室内风扇32的转速R，通过公式3，计算得到当前的目标送风距离ρmax。
ρmax＝K3*R+K4       公式3
其中，K3为距离常数，K4为截距，在本公开一些实施例中，K3和K4都为常数。
步骤S22，根据室内机30的出风温度Ta_out、回风温度Ta、出风风速Va_out、用户距离ρ和目标送风距离ρmax，计算目标风温和目标风速。需要说明的是，目标风温Taρ为与室内出风口34之间的距离为用户距离ρ的出风气流带中心的风温，目标风速Vaρ为与室内出风口34之间的距离为用户距离ρ的出风气流带中心的风速。
图9是根据一些实施例的空调器的风温与送风距离的关系图，如图9所示，将出风气流带中心的目标风温Taρ与用户距离ρ线性拟合为一次函数，例如，当ρ＝0时，Ta0＝Ta_out；当ρ＝ρmax时，Taρmax＝Ta。
根据不同的用户距离ρ，结合回风温度Ta、出风温度Ta_out和目标送风距离ρmax，通过公式4计算出与用户距离ρ相对应的出风气流带中心的目标风温Taρ。
例如，如图9所示，当ρ＝1.5m时，
再例如，当ρ＞ρmax时，Taρ＝Ta。
图10是根据一些实施例的空调器的风速和送风距离的关系图，如图10所示，将出风气流带中心的风速Va与用户距离ρ线性拟合为一次函数，例如，当ρ＝0时，Va0＝Va_out；当ρ＝ρmax时，Vaρmax＝0。
根据不同的用户距离ρ，结合出风风速Va_out和目标送风距离ρmax，通过公式5计算出与用户距离ρ相对应的出风气流带中心的目标风速Vaρ。
例如，如图10所示，当ρ＝1.5m时，
再例如，当ρ＞ρmax，Vaρ＝0。
步骤S23，根据预设的风温、风速和标准有效温度的对应关系，确定目标风温Taρ和目标风速Vaρ对应的标准有效温度SET，作为实时标准有效温度SETρ。
在本公开一些实施例中，预先设定风温、风速和标准有效温度的对应关系，例如，如表2所示。
表2风温、风速和标准有效温度的对应关系

需要说明的是，表2为通过SET＝f(Ta,Va)的函数解耦出的风温-风速-标准有效温度关系表。表2中首行为风速，单位为m/s；左侧第一列为风温，单位为℃；表中的值为标准有效温度SET，单位为℃。
在本公开一些实施例中，风速可以为出风风速Va_out、目标风速Vaρ等；风温可以为 回风温度Ta、出风温度Ta_out、目标风温Taρ等；标准有效温度可以为实时标准有效温度SETρ、目标标准有效温度SETs等。
标准有效温度SET和回风温度Ta的最小分度由空调器10的室内环境温度传感器521的精度确定。例如，当室内环境温度传感器521的精度为0.5℃时，标准有效温度SET、回风温度Ta的最小分度为0.5℃；当室内环境温度传感器521的精度为0.1℃时，标准有效温度SET、回风温度Ta的最小分度为0.1℃。
控制器40在得到用户距离ρ处的目标风温Taρ和目标风速Vaρ之后，根据表2得到用户距离ρ处的实时标准有效温度SETρ。
表3标准有效温度、风速和风温的对应关系
需要说明的是，表3为通过Ta＝f(SET,Va)的函数解耦出的标准有效温度-风速-风温关系表。表3中首行为风速，单位为m/s；左侧第一列为标准有效温度SET，单位为℃；表中的值为风温，单位为℃。
在得到当前设定的目标标准有效温度SETs和当前设定的目标风速Vaρ之后，根据表3得到目标风温Taρ。例如，当用户设定目标标准有效温度SETs为25℃，目标风速Vaρ为 0.3m/s时，根据表3可得目标风温Taρ＝25.5℃。
在本公开一些实施例中，空调器10可以接受云服务器通过公式求解计算程序计算出的目标参数。带操作系统的控制器40还可以采用直接通过公式求解出目标参数，例如根据公式4计算得到目标风温Taρ。对于芯片的计算能力不能达到通过公式精准计算的控制器40，还可以通过查表2或表3获取目标参数。
在本公开一些实施例中，表4为室内风扇32的转速R和压缩机的运行频率F对目标风温Taρ、目标风速Vaρ、以及实时标准有效温度SETρ的影响。
表4室内风扇的转速和压缩机的运行频率对目标风温、目标风速以及实时标准有效温度的影响
由表4可知，室内风扇32的转速R的变化对目标风温Taρ的影响可以忽略不计，然而，室内风扇32的转速R的变化对目标风速Vaρ和实时标准有效温度SETρ有重要影响(例如，室内风扇32的转速R上升，则目标风速Vaρ上升，实时标准有效温度SETρ下降)。压缩机21的运行频率F的变化对目标风速Vaρ无影响，然而，压缩机21的运行频率F的变化对目标风温Taρ和实时标准有效温度SETρ有重要影响(例如，压缩机21的运行频率F上升，则目标风温Taρ下降，实时标准有效温度SETρ下降)。
根据表3和表4可知，当空调器10运行在制冷模式时，在标准有效温度SET一定的情况下，存在多组风温和风速的组合。例如，设定的目标标准有效温度SETs＝16℃时，存在(17℃,0.3m/s)、(17.5℃,0.6m/s)、(18.5℃,0.8m/s)、(19℃,1.0m/s)、(19.5℃,1.4m/s)、(20℃,2.0m/s)、(20.5℃,3.0m/s)等多组出风风温T_out和出风风速Va_out组合，使得人体感受到的实时标准有效温度SETρ为16℃。根据上述组合可知，当人体感受到的实时标准有效温度SETρ一定时，空调器10的出风温度T_out越高，室内实际温度与空调器10的出风温度T_out的温度差值越小，压缩机21的功耗越小。然而，空调器10的出风温度T_out越高，出风风速Va_out越高，导致室内风扇32的转速R增加，室内风扇32的功耗增加。由于压缩机21的功耗大于室内风扇32的功耗，压缩机21的功耗的减小值大于室内风扇32的功耗增加值，此时空调器10实际所需输出的冷量减少，即更加节能。
表5为压缩机21的运行频率F和出风风速Va_out对空调器10的制冷能力和出风温度T_out的影响程度。
表5压缩机的运行频率和风速对空调器的制冷能力和出风温度的影响程度
需要说明的是，表5中★的数量表示影响的程度，★的数量越多表示影响的程度越大。
由表5可知，压缩机21的运行频率F的变化对空调器10的制冷能力和出风温度T_out的影响，较出风风速Va_out的变化对空调器10的制冷能力和出风温度T_out的影响要更为明显，而出风风速Va_out对室内空气温度均匀性的影响更为明显。因此，压缩机21的运行频率F对室内空气温度能否达到设定的温度有重要影响；出风风速Va_out的大小对室内空气温度的均匀性有重要影响(出风风速越大，室内空气循环越快，室内空气温度的均匀性越好)；压缩机21的运行频率F和出风风速Va_out对出风温度T_out都有较大影响，且压缩机21的运行频率F对出风温度T_out的影响大于出风风速Va_out对出风温度T_out的 影响。
当空调器10运行在制冷运行模式时，本公开一些实施例通过设定温度差值E，结合室内空气温度的均匀性等影响，在尽量满足室内空气温度达到设定的目标标准有效温度SETs，且室内空气温度的均匀性好的情况下，动态调整室内风扇32的转速R以及压缩机21的运行频率F，以实现用户测点或者用户所处位置达到预设的目标标准有效温度SETs的需求。
室内风扇32的转速R与用户设定的目标制冷温度Ts和当前的实际回风温度Ta之间的温度差值E有关。例如，目标制冷温度Ts由用户根据需求设定，温度差值E＝Ta-Ts。温度差值E越大，室内风扇32的转速R越大。温度差值E趋近于0或为负数时，则实际回风温度达到制冷目标温度，即室内空气温度达到制冷目标温度。
图11为根据一些实施例的又一种空调器的控制方法的流程图，如图11所示，在本公开一些实施例中，步骤S4包括步骤S41至S432。
步骤S41，判断实时标准有效温度SETρ是否满足SETρ<SETs-ΔT，若是，则执行步骤S42，若否，则执行步骤S43。
步骤S42，判断温度差值是否满足E≥E1，若是，则执行步骤S421，若否，则执行步骤S422。
步骤S421，维持压缩机21的运行频率F不变，并按照预设的档位调整步长减小室内风扇32的转速R。
控制器40控制室内风扇32的转速R降低ΔR，并控制压缩机21的运行频率F不变。在本公开一些实施例中，室内风扇32的档位调整步长为ΔR，减小后的室内风扇32的转速例如为R-ΔR。
步骤S422，按照预设的频率调整步长减小压缩机21的运行频率F，并按照预设的档位调整步长减小室内风扇32的转速R。
此时，温度差值E满足E＜E1，控制器40控制室内风扇32的转速R降低ΔR，并控制压缩机21的运行频率降低ΔF。在本公开一些实施例中，压缩机21的频率调整步长为ΔF，减小后的压缩机21的运行频率例如为F-ΔF。ΔF范围为0.1Hz～20Hz。
步骤S43，判断温度差值是否满足E≥E1，若是，则执行步骤S431，若否，则执行步骤S432。
步骤S431，按照预设的频率调整步长增加压缩机21的运行频率F，并按照预设的档位调整步长增加室内风扇32的转速R。
控制器40控制室内风扇32的转速R增加ΔR，并控制压缩机21的运行频率F增加ΔF。在本公开一些实施例中，增加后的室内风扇32的转速例如为R+ΔR，增加后的压缩机21的运行频率例如为F+ΔF。
步骤S432，维持压缩机21的运行频率F不变，并按照预设的档位调整步长增加室内风扇32的转速R。
此时，温度差值E满足E＜E1，控制器40控制室内风扇32的转速增加ΔR，并控制压缩机21的运行频率F不变。
在本公开一些实施例中，如图11所示，控制器40在任一时刻计算得出实时标准有效温度SETρ，并根据实时标准有效温度SETρ与标准有效温度范围[SETs-ΔT，SETs+ΔT]的关系，以及温度差值E与温度阈值E1的关系，调整压缩机21的运行频率F，或保持压缩机21的运行频率F不变后，空调器10的控制方法还包括步骤S6。
步骤S6，延时T2秒以后，重复上述步骤S1至步骤S5。
延时T2秒以后，控制器40重新获取回风温度Ta、出风温度Ta_out、出风风速Va_out和温度差值E，计算得到新的实时标准有效温度SETρ，并控制压缩机21的运行频率F以及室内风扇32的转速R，将实时标准有效温度SETρ控制在标准有效温度范围[SETs-ΔT， SETs+ΔT]内。后续以T2秒为一个检测周期，重复该过程。
T2的取值范围例如为10～600。
在本公开一些实施例中，如图11所示，空调器10运行在制冷模式时，用户预先设定空调器10的目标制冷温度Ts、室内风扇32的转速R、用户距离ρ等参数。用户开启出风标准有效温度SET功能后，当用户未自行设置目标标准有效温度SETs时，默认初始设定目标标准有效温度SETs为16℃。出风风速Va_out默认为自动控制，初始室内风扇档位为用户预先设置的档位，如1～5档或自动档。
控制器40通过温度传感器60和风速传感器70检测得到或者通过公式1和公式2间接获取出风温度T_out、出风风速Va_out，并检测得到回风温度Ta、用户距离ρ及用户与室内出风口34之间的角度θ，计算得到温度差值E(E＝Ta-Ts)。同时控制气流控制机构33，引导空调出风的气流中心吹向用户所处位置。获取当前室内风扇32的转速R，通过公式3计算得到目标送风距离ρmax。将回风温度Ta、出风温度T_out、出风风速Va_out、目标送风距离ρmax和用户距离ρ分别代入公式4和公式5，计算得到与用户距离ρ相对应的室内机30的出风气流带中心的目标风温Taρ和目标风速Vaρ，根据表2获取或通过SET＝f(Ta,Va)的函数计算得到与用户距离ρ相对应的室内机30的出风气流带中心的实时标准有效温度SETρ，并将实时标准有效温度SETρ与标准有效温度范围[SETs-ΔT，SETs+ΔT]进行比较。
当SETρ＞SETs+ΔT时，若温度差值E≥Es，则控制室内风扇32的转速R增加△R，同时控制压缩机21的运行频率F增加△F；若温度差值E＜Es，则控制室内风扇32的转速R增加△R，并控制压缩机21的运行频率F保持不变。
当SETρ＜SETs-ΔT时，若温度差值E≥Es，则控制器40控制室内风扇32的转速R减小△R，并控制压缩机21的运行频率F保持不变；若温度差值E＜Es，则控制室内风扇32的转速R减小△R，同时控制压缩机21的运行频率F减小△F。
当SETs-ΔT≤SETρ≤SETs+ΔT时，控制室内风扇32的转速R和压缩机21的运行频率F保持不变。
在延时T2秒以后，重新检测回风温度Ta、出风温度Ta_out、出风风速Va_out和温度差值E，计算得到新的实时标准有效温度SETρ，并控制压缩机21的运行频率F以及室内风扇32的转速R，将实时标准有效温度SETρ控制在标准有效温度范围[SETs-ΔT，SETs+ΔT]内，后续以T2秒为一个检测周期，重复该过程。T2的取值范围例如为10～600秒。
例如：某1.5匹机型参数设置为：ΔT＝1℃，E1＝1.5℃，T2＝60s，ΔF＝5Hz，ΔR＝100rpm，K3＝0.0033，K4＝1.3。
空调器10运行在制冷模式时，用户开启出风标准有效温度SET控制功能，设定目标标准有效温度SETs为16℃，此时标准有效温度范围[15℃,17℃]。设定目标制冷温度Ts为26℃，用户距离ρ为1.5m，用户所处位置与室内出风口34之间的θ为-10°，检测得到出风温度T_out＝12℃、出风风速Va_out＝3m/s、回风温度Ta＝27℃，此时温度差值E＝Ta-Ts＝27-26＝1℃，室内风扇32的档位4档，室内风扇32的转速R为1050rpm，控制气流控制机构33向与室内出风口34之间的夹角为-10°的方向送风。通过公式3计算出ρmax＝K3×R+K4＝0.0033×1050+1.3≈4.8m。将Ta＝27℃、Ta_out＝12℃、Va_out＝3m/s、ρmax＝4.8m、ρ＝1.5m分别代入公式4和公式5，计算得到与室内出风口34之间的距离为1.5m的气流带中心的目标风温Ta1.5＝1.5(Ta-Ta_out)/ρmax+Ta_out＝1.5×(27-12)/4.8+12≈16.8℃(取0.2的整数倍)、Va1.5＝-1.5Va_out/ρmax+Va_out＝-1.5×3/4.8+3≈2.0m/s。根据表2获取或通过SET＝f(Ta,Va)的函数计算出此时室内机30的出风气流带中心的实时标准有效温度SET1.5≈10℃＜15℃，此时E＝27-26＝1℃＜1.5℃，E＜E1。控制器40控制室内风扇32的转速R减小100rpm，压缩机21的运行频率减小5Hz。
延时一个周期T2秒后，重新检测得到出风温度T_out＝15℃、出风风速Va_out＝2.7m/s、回风温度Ta＝26.5℃、温度差值E＝26.5-26＝0.5℃，转速R为950rpm。根据公式3计算得到 ρmax＝K3*R+K4＝0.0033*950+1.3≈4.4m。将Ta＝26.5℃、Ta_out＝15℃、Va_out＝2.7m/s和ρmax＝4.4m分别代入公式4和公式5，分别计算得到与室内出风口34之间的距离为1.5m的气流带中心的目标风温Ta1.5＝1.5(Ta-T_out)/ρmax+T_out＝1.5(26.5-15)/4.8+15≈19℃(取0.2的整数倍)、目标风速Va1.5＝-1.5Va_out/ρmax+Va_out＝-1.5*2.7/4.4+2.7≈1.8m/s。根据表2获取或通过SET＝f(Ta,Va)的函数计算得到此时的实时标准有效温度SET1.5≈13.2℃＜15℃，此时E＝26.5-26＝0.5℃，E＜E1。控制器40控制转速R下降100rpm，压缩机21的运行频率F减小5Hz(△F＝5Hz)。
预设周期后，检测得到风温度T_out＝18℃、出风风速Va_out＝2.0m/s、回风温度Ta＝26℃、温度差值E＝26-26＝0℃，转速R为750rpm。根据公式3计算得到ρmax＝K3*R+K4＝0.0033*750+1.3≈3.8m。将Ta＝26℃、T_out＝18℃、Va_out＝2.2m/s、ρmax＝3.8m分别代入公式4和公式5，计算得到与室内出风口34之间的距离为1.5m的气流带中心的目标风温Ta1.51.5(Ta-T_out)/ρmax+T_out＝1.5(26-18)/3.7+18≈21.2℃、目标风速Va1.5＝-1.5Va_out/ρmax+Va_out＝-1.5*2.2/3.8+2.2≈1.4m/s。根据表2获取或通过SET＝f(Ta,Va)的函数计算得到此时的实时标准有效温度SET1.5≈16.5℃∈[15,17]，达到了用户设定的目标标准有效温度SETs＝16℃的需求，此时控制器40控制室内风扇32的转速R和压缩机21的运行频率F保持不变。
本公开一些实施例提供了一种空调器的控制方法，由于人体实际感受到的温度为温度、湿度、风速综合的真实体感感受，而标准有效温度以温度、湿度、风速等参数为基础，反映实际温度、湿度、风速在人体身上的真实感受。且空调器10通常单一地以风温作为控制目标，如果不考虑风速，单维度的控制风温，对压缩机21的运行频率的要求较低，则降低空调器10的制冷量的输出，延长了室内空气达到设定的目标标准有效温度SETs的时间，甚至始终达不到目标标准有效温度SETs。因此，本公开一些实施例引入了标准环境温度SET的概念，通过同时考虑风速和风温两个影响因素来实现对压缩机21的运行频率的控制，使得在整体室内空气温度达到舒适区间的基础上还不会大幅降低空调器10的制冷量的输出。
