图1是本申请提供的基于体感温度的变频控制方法的流程示意图；
图2是本申请提供的基于体感温度的变频控制装置的结构示意图；
图3是本申请提供的空调器中控制器的实体结构示意图。
具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下面结合图1-图3描述本申请的一种基于体感温度的变频控制方法、装置、空调器及存储介质。
图1是本申请提供的基于体感温度的变频控制方法的流程示意图，如图1所示，包括：
步骤110，确定用户的体感温度；体感温度是基于室内环境温度和室内环境湿度确定的；
具体地，本申请实施例所描述的用户的体感温度又称表观气温，是实时测算到的用户体感温度。
可以理解的是，体感温度是人体对外界环境冷暖的感觉，既不是人体的皮肤温度，也不是天气预报描述的气温。影响人体体感温度主要包括四个因素，分别是气温、湿度、风速和太阳辐照度，前三个因素对人体的影响最大，它比单纯的环境温度更能反映环境的舒适度。
其中，用户的体感温度可以通过下述公式计算得到：
T＝Ta+Tb+Tc-Tv；
其中，T表示用户的体感温度；Ta表示室内环境温度，是干扰体感温度的关键因素；Tb表示室内环境湿度；Tc表示辐射项；Tv表示室内风速。
在本申请实施例中，还可以通过酷热指数(Heat Index)计算方法，通过获取室内温度和室内相对湿度，室内相对湿度可以根据室内环境湿度计算得到，从Heat Index测算表中确定用户的体感温度。
在本申请的实施例中，确定用户的体感温度还可以是其他用于测量用户的体感温度的实施方式进行确定，如采用体感温度测量装置对用户的体感温度进行实时监测及获取，本申请对此不做具体限定。
步骤120，获取用户的体感温度和目标体感温度之间的温差；
在本步骤中，本申请实施例所描述的目标体感温度指的是用户最佳的体感温度，如25℃。其可以是系统默认的最佳体感温度，也可以是用户根据个人生理情况设定的最佳体感温度。
在本申请实施例中，当用户开启空调器后，空调器可以通过室内机中设置的温度传感器、湿度传感器等，实时采集室内环境温度和室内环境湿度等信息，确定出用户的体感温度，并将用户的体感温度和目标体感温度进行温差计算，获取用户的体感温度和目标体感温度之间的温差。
在本申请实施例中，空调器制热时，可以通过目标体感温度减去用户的体感温度，来获取用户的体感温度和目标体感温度之间的温差；空调器制冷时，通过用户的体感温度减去目标体感温度，来获取用户的体感温度和目标体感温度之间的温差。
步骤130，基于该温差和预设温差阈值分段区间，确定空调压缩机的目标运行频率，并控制空调压缩机在该目标运行频率下运行；
预设温差阈值分段区间包括多段温差阈值区间，每段温差阈值区间对应有一种目标运行频率的确定方式。
具体地，本申请实施例所描述的预设温差阈值分段区间是预先设置的分段控制阈值区间，其可以包括连续的多段温差阈值区间，每段温差阈值区间都可以对应有一个特定的频率计算方式，以确定出目标运行频率，控制空调压缩机的运行。
在本实施例中，预设温差阈值分段区间具体可以根据实际空调器的配置信息和设计需求进行设定，本申请对此不做具体限定。
本申请实施例所描述的目标运行频率指的是根据用户的体感温度和目标体感温度之间的温差，从预设温差阈值分段区间中确定对应的温差阈值区间，根据该温差阈值区间对应的频率确定方式得到的空调压缩机运行频率。
进一步地，可以基于用户的体感温度和目标体感温度之间的温差以及预设温差阈值分段区间，可以计算出空调压缩机的目标运行频率，并控制空调压缩机在目标运行频率下运行，从而高效地对变频空调器进行频率调控，进行快速制冷或制热，实现对室内环境温湿度的快速调节。
本申请提供的基于体感温度的变频控制方法，通过从用户实际体感舒适度的角度出发，在获取室内环境温度和室内环境湿度，确定用户的体感温度后，实时获取用户的体感温度与表征人体最佳体感舒适度的目标体感温度之间的温差，根据基于该温差的分段控制逻辑，从预设温差阈值分段区间中确定该温差所属的温差阈值区间及对应的目标运行频率确定方式，从而得到空调压缩机的目标运行频率，并控制空调压缩机在目标运行频率下运行，可以高效地对变频空调器进行频率调控，进行快速制冷或制热，实现对室内环境温湿度的快速调节，确保用户的体感温度可以快速达到人体最佳体感舒适度，用户体验佳。
基于上述实施例的内容，作为一种可选的实施例，基于该温差和预设温差阈值分段区间，确定空调压缩机的目标运行频率，包括：
在该温差包含于预设温差阈值分段区间中的第一温差阈值区间的情况下，确定目标运行频率为空调压缩机的最大频率。
具体地，本申请实施例所描述的第一温差阈值区间可以是预设温差阈值分段区间的连续多段温差阈值区间中，表征用户的体感温度与目标体感温度之间温差最大的阈值区间，其可以表示为大于第一温差阈值的区间，其中，第一温差阈值可以取值为5℃、6℃、8℃等。
需要说明的是，由于现有变频空调器频率控制逻辑是由室外环境温度决定的，当用户的体感温度与目标体感温度之间的温差很大，用户需要快速制冷或制热，而室外环境温度使空调压缩机的运行频率并不高，导致变频空调器调频时间过长，而不能进行快速制冷或制热。
在本实施例中，获取用户的体感温度与目标体感温度之间的温差，在 该温差包含于预设温差阈值分段区间中的第一温差阈值区间的情况下，说明此时用户的体感非常不舒适，需要进行快速制冷或制热，由此，此时可以根据第一温差阈值区间对应的目标运行频率确定方式，确定目标运行频率为空调压缩机的最大频率，即此时将空调压缩机调节至最大频率运行，以实现快速制冷或制热。
本申请实施例的方法，当用户的体感温度与目标体感温度之间的温差很大时，控制空调压缩机以最大频率运行，加速制冷或制热，无须受制于室外环境温度的影响，极大地提升了变频空调器进行频率调节的效率，确保用户的体感温度可以快速达到人体最佳体感舒适度，用户体验佳。
基于上述实施例的内容，作为一种可选的实施例，基于该温差和预设温差阈值分段区间，确定空调压缩机的目标运行频率，包括：
在该温差包含于预设温差阈值分段区间中的第二温差阈值区间的情况下，确定空调压缩机的目标运行频率；
目标运行频率是基于目标固定频率和目标频率变化阈值确定的，目标固定频率是基于当前室外环境温度确定的。
具体地，本申请实施例所描述的第二温差阈值区间可以是预设温差阈值分段区间的连续多段温差阈值区间中，处于中间分段的阈值区间，当第一温差阈值取值为5℃，其可以取值为0℃～1℃，1℃～3℃，或3℃～5℃。
本申请实施例所描述的目标固定频率指的是空调器预先设定的基于室外环境温度确定的空调压缩机运行频率。例如，空调器制热时，室外环境温度在5℃至10℃，空调压缩机对应在一个固定频率运行；室外环境温度0℃至5℃，空调压缩机对应在另一个固定频率运行。
本申请实施例所描述的目标频率变化阈值可以根据所属温差阈值区间的温差阈值大小设定，也就是说，温差阈值较大的温差阈值区间对应的目标频率变化阈值可以设定大一些，温差阈值较小的温差阈值区间对应的目标频率变化阈值可以设定小一些。例如，第二温差阈值区间为1℃～3℃时，目标频率变化阈值可以取值为5Hz、6Hz、7Hz等；第二温差阈值区间为3℃～5℃时，目标频率变化阈值可以取值为10Hz、11Hz、12Hz等，本申请实施例中对此不做具体限定。
基于上述实施例的内容，作为一种可选的实施例，在该温差包含于预 设温差阈值分段区间中的第二温差阈值区间的情况下，确定空调压缩机的目标运行频率，包括：
在该温差包含于第一阈值子区间的情况下，确定空调压缩机的目标运行频率为第一运行频率；
其中，第一运行频率是基于目标固定频率与目标频率变化阈值求和得到的，第二温差阈值区间包括第一阈值子区间。
具体地，本申请实施例所描述的第一阈值子区间指的是第二温差阈值区间中，可以表征用户的体感温度与目标体感温度之间的温差较大的阈值区间。
示例性地，在本实施例中，当第一温差阈值取值为5℃，第二温差阈值区间可以取值为0℃～1℃，1℃～3℃，或3℃～5℃，那么第一阈值子区间可以是1℃～3℃，或3℃～5℃。
本申请实施例所描述的第一运行频率指的是基于第一阈值子区间对应的目标运行频率确定方式得到的，其可以是目标固定频率与目标频率变化阈值求和得到的频率，其用于在用户的体感温度与目标体感温度之间的温差包含于第一阈值子区间的情况下，控制空调压缩机的运行。
在本申请实施例中，目标频率变化阈值可以根据所属温差阈值区间的温差阈值大小设定，如第一阈值子区间为1℃～3℃时，目标频率变化阈值可以为6Hz；第一阈值子区间为3℃～5℃时，目标频率变化阈值可以为12Hz；
也就是说，在用户的体感温度与目标体感温度之间的温差包含于第一阈值子区间如1℃～3℃的情况下，根据第一阈值子区间对应的目标运行频率确定方式，第一运行频率可以基于目标固定频率与目标频率变化阈值求和得到，如目标固定频率为35Hz，目标频率变化阈值为6Hz，则此时第一运行频率为41Hz，由此，可以确定空调压缩机的目标运行频率为41Hz；
在用户的体感温度与目标体感温度之间的温差包含于第一阈值子区间如3℃～5℃的情况下，如目标固定频率为35Hz，目标频率变化阈值为12Hz，则此时第一运行频率为47Hz，可以确定空调压缩机的目标运行频率为47Hz。由此，在确定空调压缩机的目标运行频率之后，可以控制空调压缩机在目标运行频率下运行。
在本申请实施例中，当检测到用户的体感温度与目标体感温度之间的 温差较大时，在原有基于室外环境温度决定的目标固定频率的基础上，进一步增大空调压缩机的运行频率，极大地提升了变频空调器进行频率调节的效率，有利于促进用户的体感温度快速达到人体最佳体感舒适度，提升用户体验。
基于上述实施例的内容，作为一种可选的实施例，在该温差包含于预设温差阈值分段区间中的第二温差阈值区间的情况下，确定空调压缩机的目标运行频率，包括：
在该温差包含于第二阈值子区间的情况下，确定空调压缩机的目标运行频率为第二运行频率；
其中，第二运行频率是基于目标固定频率与目标频率变化阈值的差值得到的，第二温差阈值区间包括第二阈值子区间。
具体地，本申请实施例所描述的第二阈值子区间指的是第二温差阈值区间中，可以表征用户的体感温度与目标体感温度之间的温差较小的阈值区间。
示例性地，在本实施例中，当第一温差阈值取值为5℃，第二温差阈值区间可以取值为0℃～1℃，1℃～3℃，或3℃～5℃，那么第二阈值子区间可以是0℃～1℃。
本申请实施例所描述的第二运行频率指的是基于第二阈值子区间对应的目标运行频率确定方式得到的，其具体可以是根据目标固定频率与目标频率变化阈值的差值得到的，其用于在用户的体感温度与目标体感温度之间的温差包含于第二阈值子区间的情况下，控制空调压缩机的运行。
在本申请实施例中，目标频率变化阈值可以根据所属温差阈值区间的温差阈值大小设定，如第二阈值子区间为0℃～1℃时，目标频率变化阈值可以为5Hz；
也就是说，在用户的体感温度与目标体感温度之间的温差包含于第二阈值子区间如0℃～1℃的情况下，根据第二阈值子区间对应的目标运行频率确定方式，第二运行频率可以基于目标固定频率与目标频率变化阈值的差值得到，如目标固定频率为50Hz，目标频率变化阈值为6Hz，则此时第二运行频率为44Hz，由此，可以确定空调压缩机的目标运行频率为44Hz，控制空调压缩机在44Hz运行。
在本申请实施例中，当检测到用户的体感温度与目标体感温度之间的温差较小时，在原有基于室外环境温度决定的目标固定频率的基础上，进一步减小空调压缩机的运行频率，有利于空调器平稳地进入PID控制模式，在提升变频空调器进行频率调节的效率以及稳定性的同时，使得空调器的运行功耗得到大幅度降低。
由此，在确定用户的体感温度与目标体感温度之间的温差用户的体感温度与目标体感温度之间的温差包含于预设温差阈值分段区间中的第二温差阈值区间的情况下，基于第二温差阈值区间对应的目标运行频率确定方式，可以确定空调压缩机的目标运行频率，进而可以控制空调器压缩机在目标运行频率下运行，实现对变频空调器的高效调频，确保用户的体感温度可以快速达到人体最佳体感舒适度。
本申请实施例的方法，通过在原有室外环境温度调频方式的基础上，设定多段温差阈值区间的调控区间，针对实际用户的体感温度与目标体感温度之间的温差，动态确定空调压缩机的目标运行频率，实现对变频空调器的高效调频，确保用户的体感温度可以快速达到人体最佳体感舒适度，用户体验佳。
基于上述实施例的内容，作为一种可选的实施例，基于该温差和预设温差阈值分段区间，确定空调压缩机的目标运行频率，包括：
在该温差包含于预设温差阈值分段区间中的第三温差阈值区间的情况下，进入比例积分微分(Proportion Integral Differential，PID)控制模式；
在PID控制模式下，确定空调压缩机的目标运行频率。
具体地，本申请实施例所描述的第三温差阈值区间可以是预设温差阈值分段区间的连续多段温差阈值区间中，表征用户的体感温度与目标体感温度之间的温差为负值的阈值区间，其可以为小于第二温差阈值的区间，即第二温差阈值为0℃。
在本实施例中，在确定用户的体感温度与目标体感温度之间的温差为负值，即该温差包含于预设温差阈值分段区间中的第三温差阈值区间的情况下，可以控制空调器直接进入PID控制模式；通过在PID控制模式下，基于PID控制原理，计算空调压缩机的目标运行频率，动态调节空调压缩机的运行频率，控制变频空调器的运行。
本申请实施例的方法，通过考虑实际用户的体感温度与目标体感温度之间的温差，在该温差为负值时控制变频空调器进入PID控制模式，可以更加有效地实现变频空调器平稳过渡到PID控制，提高变频空调器的调频效率。
可选地，在本申请的一个具体实施例中，通过检测室外环境温度，来确定空调压缩机的初始运行频率，进而通过检测用户的体感温度与目标体感温度之间的温差，若该温差在第一温差阈值区间上，即该温差大于5℃，则控制空调压缩机以最大频率运行；
若该温差在第二温差阈值区间中的第一阈值子区间3℃～5℃上，则在初始运行频率的基础上加上12HZ，以此确定空调压缩机的第一运行频率；若该温差在第二温差阈值区间中的第一阈值子区间1℃～3℃之间，则在初始运行频率的基础上加上6HZ，以此确定空调压缩机的第一运行频率；
若该温差在第二温差阈值区间中的第二阈值子区间0℃～1℃上，则在初始运行频率的基础上减去6HZ，以此确定空调压缩机的第二运行频率；
若该温差在第三温差阈值区间上，即该温差低于0℃，则控制空调器直接进入PID控制模式进行调频。
