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、膨胀阀60和风速传感器70。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和室内出风口33(即空调器10的出风口)。室外机20或室内机30中的至少一个设置有膨胀阀60。
压缩机21、冷凝器(室内换热器31或室外换热器22)、膨胀阀60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60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。
膨胀阀60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60包括室外电子膨胀阀61和室内电子膨胀阀62。由电子膨胀阀60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、膨胀阀60以及风速传感器70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。在本公开一些实施例中，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。
如图2所示，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被配置为检测实际的室内空气温度，出风温度传感器522被配置为检测室内机的出风温度，盘管温度传感器523被配置为检测室内盘管处的温度。
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。
空调器10通常将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，并且，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，难以较好地实现房间整体温度的均匀性要求，且难以满足用户对体感舒适温度的要求。
相关技术中，通过对温度、风速以及湿度这三个参数的控制，来满足用户对体感舒适温度的要求。然而，这种控制方式复杂程度高，对空调器10的设备要求高，控制器40也难以做到对温度、风速以及湿度的共同控制。
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，应用到控制器上。本公开一些实施例的空调器的控制方法，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，使得对空调器10的运行频率的调整更加精准有效，使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，且复杂程度相对较低，可以更好地为用户提供舒适的环境。
图3是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S11至S15。
步骤S11，获取当前设定的标准有效温度范围和目标送风距离，并检测实际回风温度、实际出风温度和实际风速。
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(实际回风温度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＝实际回风温度Ta，相对湿度Rh为空调器10检测的湿度，空调器10制冷运行时，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一般在40％～70％之间，默认为50％。夏季服装热阻0.6clo，代谢率为1.0M。这样将SET＝f(Ta，Va，Rh，Tr，M，clo)计算程序，简化为通过实际回风温度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风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℃]。
用户可以根据自身所在位置确定自身与空调器10之间的距离，或者，根据自身工作、学习或休闲处(记为用户设定测点)与空调器10之间的距离，确定目标送风距离ρ。图4是根据一些实施例的空调器的室内机的一个示意图，图5是根据一些实施例的空调器的室内机的另一个示意图，如图4和图5所示，室内出风口33处温度较低，用户通常不会较长时间站在室内出风口33处，而是位于与室内出风口33的距离为1m以上的位置，因此，用户可以设置气流带中心与室内出风口33的距离例如为1.5m，此时目标送风距离ρ为1.5m。若用户可接受自身与室内出风口33的距离为1.5m处的风温，随着二者之间距离的增加，风温上升，风速下降，标准有效温度SET上升，使得用户感受的标准有效温度SET随距离增加而增加，也会满足用户期望空调器10制冷出风不太凉的需求。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，则空调器10的制冷量的输出较低，延长了室内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。
实际回风温度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。
实际出风温度Ta_out可通过安装在室内出风口33处的出风温度传感器522测得，当然，实际出风温度Ta_out还可以通过公式1计算得到。
Ta_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。
实际风速Va_out可通过安装在室内出风口33处的风速传感器70测得，当然，实际风速Va_out还可以通过公式2计算得到。
Va_out＝K2×R      公式2
其中，R为室内风扇32的转速，K2为风速系数。
步骤S12，根据实际回风温度Ta、实际出风温度Ta_out、实际风速Va_out和目标送风距离ρ，计算实际标准有效温度SETρ。
步骤S13，判断实际标准有效温度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S14，若否，则执行步骤S15。
步骤S14，调整压缩机21的运行频率F和室内风扇32的转速R。
步骤S15，维持压缩机21的运行频率F和室内风扇32的转速R不变。
图6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6所示，在本公开一些实施例中，步骤S12包括步骤S121至S123。
步骤S121，获取当前设定的室内风扇32的转速R，并根据该转速R，计算当前的最远送风距离。
在本公开一些实施例中，空调器10的最远送风距离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，最远送风距离ρmax越大。
例如，图8是根据一些实施例的空调器的出风气流带中心距离与风速的关系图，其中，室内风扇32的转速R、送风距离和风速Va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中首行为气流带中心与室内出风口33之间的距离，即送风距离，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与最远送风距离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，计算得出当前的最远送风距离ρmax。
ρmax＝K3×R+K4      公式3
其中，K3和K4分别为预设的距离常数，例如：K3＝0.0033，K4＝1.3。
用户根据自身需求调整室内风扇32的档位，来实现对室内风扇32的转速R的调整， 进而调整空调器10的出风吹到用户自身时风速的大小。室内风扇32的档位越大，对应的室内风扇32的转速R越大。室内风扇32的档位的等级和每一等级对应的室内风扇32转速R范围可以根据实际情况进行设定，本公开对此不作限定。
步骤S122，根据实际回风温度Ta、实际出风温度Ta_out、实际风速Va_out、目标送风距离ρ和最远送风距离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33之间的距离为目标送风距离ρ的气流带中心的风温，目标风速Vaρ为与室内出风口33之间的距离为目标送风距离ρ的气流带中心的风速。
图9是根据一些实施例的空调器的风温和送风距离的关系图，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9和图10所示，在室内风扇32的转速R确定时，不同目标送风距离ρ处的目标风温Taρ可以与目标送风距离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。
根据不同的目标送风距离ρ，结合实际回风温度Ta、实际出风温度Ta_out和最远送风距离ρmax，通过公式4计算出与室内出风口33之间的距离为目标送风距离ρ的气流带中心的目标风温Taρ。
例如，如图9所示，当目标送风距离ρ＝1.5m时，目标风温
在室内风扇32的转速R确定时，由表1和图10可知，不同目标送风距离ρ处的目标风速Vaρ与目标送风距离ρ可以线性拟合为一次函数，例如，当ρ＝0时，Va0＝Va_out；当ρ＝ρmax时，Vaρmax＝0。
根据不同的目标送风距离ρ，结合实际回风温度Ta、实际风速Va_out和最远送风距离ρmax，通过公式5计算出与室内出风口33之间的距离为目标送风距离ρ的气流带中心的目标风速Vaρ。
例如，如图10所示，当目标送风距离ρ＝1.5m时，目标风速
步骤S123，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，作为实际标准有效温度SETρ。
在本公开一些实施例中，在预设的风温、风速和标准有效温度的对应关系中，标准有效温度SET和风温呈正相关关系，标准有效温度SET和风速呈负相关关系。
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中首行为气流中心带的风速Va，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℃。
需要说明的是，风速可以为实际风速Va_out、目标风速Vaρ等；风温可以为实际回风温度Ta、目标风温Taρ、实际出风温度Ta_out等；标准有效温度可以为实际标准有效温度SETρ、目标标准有效温度SETs等。
标准有效温度SET和实际回风温度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、实际回风温度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、实际回风温度Ta的最小分度为0.1℃。
在得到目标送风距离ρ处的目标风温Taρ和目标风速Vaρ之后，根据表2得到目标送风距离ρ处的实际标准有效温度SETρ。例如，当计算得到与室内出风口33之间的距离为1.5m的气流带中心的目标风温Taρ为21℃，目标风速Vaρ为0.4m/s时，根据表2可得实际标准有效温度SETρ＝18.5℃。
在本公开一些实施例中，当空调器10运行在制冷模式时，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，温度差值E越大，室内风扇32的转速R越大。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。
需要说明的是，压缩机21的运行频率F对室内空气温度能否达到目标标准有效温度SETs有重要影响，风速大小对室内空气温度的均匀性有重要影响，风速越大，越有利于促进室内空气循环，室内整体温度的均匀性越好。压缩机21的运行频率F和风速对空调器10的出风温度都有较大影响，压缩机21的运行频率F对空调器10的出风温度的影响程度比风速对空调器10的出风温度的影响程度大。本公开一些实施例中空调器的控制方法，通过标准有效温度SET和温度差值E组合，结合风速大小对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目标标准有效温度SETs，且室内空气温度均匀性好的情况下，动态调整室内风扇32的转速R和压缩机21的运行频率F，实现目标送风距离ρ处的设定测点达到目标标准有效温度SETs的需求。
图7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7所示，在本公开一些实施例中，步骤S14包括步骤S141至S1432。
步骤S141，判断实际标准有效温度SETρ是否满足SETρ<SETs-ΔT，若是，则执行步骤S142，若否，则执行步骤S143。
步骤S142，判断温度差值是否满足E≥Es，若是，则执行步骤S1421，若否，则执行步骤S1422。
在本公开一些实施例中，Es为预设的温度阈值。
步骤S1421，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减小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S1422，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＜Es，控制器40控制室内风扇32的转速R减小ΔR，并控制压缩机21的运行频率减小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S143，判断温度差值是否满足E≥Es，若是，则执行步骤S1431，若否，则执行步骤S1432。
步骤S1431，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S1432，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＜Es，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7所示，空调器10运行在制冷模式时，用户根据需求设定目标制冷温度Ts、室内风扇32的转速R、目标送风距离ρ等参数。用户开启出风标准有效温度SET功能后，根据自身需求设定目标标准有效温度SETs，从而得到标准有效温度范围为[SETs-ΔT，SETs+ΔT]。控制器40检测得到实际出风温度Ta_out、实际风速Va_out、实际回风温度Ta，并根据目标制冷温度Ts和实际回风温度Ta计算得到温度差值E，根据当前的室内风扇32的转速R，代入公式3计算出最远送风距离ρmax。将实际回风温度Ta、实际出风温度Ta_out、实际风速Va_out和最远送风距离ρmax分别代入公式4和公式5，计算得到与室内出风口33之间的距离为目标送风距离ρ的气流带中心的目标风温Taρ和目标风速Vaρ，根据表2获取与室内出风口33之间的距离为目标送风距离ρ的气流带中心 的实际标准有效温度SETρ。将实际标准有效温度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，则控制器40控制室内风扇32的转速R增加ΔR，同时控制压缩机21的运行频率F增加ΔF；若温度差值E＜Es，则控制器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ΔR，并控制压缩机21的运行频率F保持不变；若温度差值E＜Es，则控制器40控制室内风扇32的转速R减小ΔR，同时控制压缩机21的运行频率F减小ΔF。
当SETs-ΔT≤SETρ≤SETs+ΔT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。
在本公开一些实施例中，控制器40在任一时刻计算得出实际标准有效温度SETρ，并根据实际标准有效温度SETρ与标准有效温度范围[SETs-ΔT，SETs+ΔT]的关系，以及温度差值E与目标温度差值Es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S16。
步骤S16，延时T1秒以后，重复上述步骤S11至步骤S15。
延时T1秒以后，控制器40重新获取实际回风温度Ta、实际出风温度Ta_out、实际风速Va_out和温度差值E，计算得到新的实际标准有效温度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，将实际标准有效温度SETρ控制在标准有效温度范围[SETs-ΔT，SETs+ΔT]内。后续以T1秒为一个检测周期，重复该过程。
T1的取值范围例如为10～600。
例如，某1.5匹机型参数设置为：ΔT＝1℃，Es＝1.5℃，T1＝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℃，目标送风距离ρ为1.5m，控制器40检测得到实际出风温度Ta_out＝12℃、实际风速Va_out＝3m/s、实际回风温度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。通过公式3计算出最远送风距离ρmax＝K3×R+K4＝0.0033×1050+1.3≈4.8m。将Ta＝27℃、Ta_out＝12℃、Va_out＝3m/s、ρmax＝4.8m分别代入公式4和公式5，计算得出与室内出风口33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℃、Va1.5＝-1.5Va_out/ρmax+Va_out＝-1.5×3/4.8+3≈2.0m/s。根据表2此时的实际标准有效温度SET1.5≈10℃＜15℃，此时E＝27-26＝1℃，E＜Es，控制室内风扇32的转速R减小100rpm，压缩机21的运行频率F减小5Hz。
延时一个周期T1后，控制器40重新检测得到实际出风温度Ta_out＝15℃、实际风速Va_out＝2.7m/s、实际回风温度Ta＝26.5℃，温度差值E＝26.5-26＝0.5℃，转速R为950rpm。根据公式3计算得出ρmax≈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33之间的距离为1.5m的气流带中心的目标风温Ta1.5≈19℃、目标风速Va1.5≈1.8m/s。根据表2获取此时的实际标准有效温度SET1.5≈13℃＜15℃，此时E＝26.5-26＝0.5℃，E＜Es，控制器40控制转速R减小100rpm，压缩机21的运行频率F减小5Hz。
预设周期后，控制器40检测得到实际出风温度Ta_out＝18℃、实际风速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≈3.8m。将Ta＝26℃、Ta_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33之间的距离为1.5m的气流带中心的目标风温Ta1.5≈21.2℃、目标风速Va1.5≈1.4m/s。根据表2获取与室内出风口33之间的距离为 1.5m的气流带中心的实际标准有效温度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，通过获取当前设定的标准有效温度范围和目标送风距离，并检测实际回风温度、实际出风温度和实际风速；根据实际回风温度、实际出风温度、实际风速和目标送风距离，计算实际标准有效温度SETρ；当实际标准有效温度SETρ处于标准有效温度范围外时，调整压缩机21的运行频率F和室内风扇32的转速R；否则，维持压缩机的运行频率F和室内风扇32的转速R不变。
本公开一些实施例的空调器的控制方法，引入了标准环境温度SET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F以及室内风扇32的转速R的控制，使得对空调器10的运行频率F的调整更加精准有效，且控制方法复杂程度相对较低。在保证达到用户所需的目标标准有效温度SETs，减少空调器10出风吹到人体的不舒服感的基础上，还能有效兼顾整体室内空气温度达到舒适区间，避免室内空气整体温度达不到设定的标准有效温度SET，或达到设定的标准有效温度SET的时间变长的情况。本公开一些实施例通过用户设定的目标送风距离ρ、室内风扇档位等信息，来计算用户设定测点的实际标准有效温度SETρ，实现对空调器10的运行参数的调整，使得用户设定测点的标准有效温度SET能够尽快达到用户所需的目标标准有效温度SETs，更好地为用户提供一个舒适的空调环境。
