Description

多联机空调器及其控制方法和控制装置 技术领域
本发明属于空气调节技术领域，具体地说，是涉及空调器，更具体地说，是涉及多联机空调器及其控制方法和控制装置。
 背景技术
多联机空调器通常包括有多个室内机，多个室内机的制冷剂管路并联，共用一个或多个室外机。对于多联机空调器，室内机通常在其回风口处设置有温度检测装置，根据该温度检测装置所检测的回风温度判断室内机是否满足达温停机条件。当有室内机满足达温停机条件后，通常的控制方案是对室内机吹余热，将室内机中积累的热量吹出，然后关闭将该室内机的节流部件。
现有技术中，多联机空调器吹余热的时间通常为空调器在出厂时即确定的固定值。部分多联机空调器采用非固定值的吹余热时间，利用进入吹余热状态时的室内风机转速确定吹余热时长。
但是，不管是采用固定值的吹余热时间，还是根据室内风机转速确定吹余热时长，其仅是从多联机空调器自身运行状态出发，未考虑室内机所安装的房间结构、室内机在房间中的安装位置、安装方式等相关因素的影响，导致在多联机空调器使用过程中，经常还会出现室内机达温停机后房间温度下降、应启动室内机但却不能再次正常启动的问题，或者会出现达温停机吹余热时吹出冷风的问题，均会造成房间温度不适宜，影响用户舒适度。

为了使本发明的目的、技术方案及优点更加清楚明白，以下将结合附图和实施例，对本发明作进一步详细说明。
需要说明的是，在本发明的描述中，术语“第一”、“第二”、“第三”、“第四”仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”、“第三”、“第四”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个、三个等，除非另有明确具体的限定。

现有多联机空调器的控制中采用的吹余热时间是从多联机空调器自身运行状态出发，未考虑室内机所安装的房间结构、室内机在房间中的安装位置、安装方式等相关因素的影响，导致室内机达温停机后房间温度下降、应启动室内机但却不能再次正常启动的问题，或者会出现达温停机吹余热时吹出冷风的问题。针对此类问题，本发明创造性地提出基于房间内人体感知温度与室内机检测温度以及室内机的内盘管温度确定计时时间，根据计时时间确定修正吹余热时间，使得吹余热时间自适应空调器的室内机安装状态，提高空调器控制的准确性和使用舒适性，实现智能空调器功能。
图1示出了本发明多联机空调器的控制方法第一个实施例的流程示意图，具体来说，是确定室内机制热运行时的吹余热时间的一个实施例的流程示意图。其中，多联机空调器包括室外机和多个室内机，该实施例的控制方法是针对其中一个室内机而言。
如图1所示意，该实施例的控制方法采用下述过程实现。
步骤101：收到室内机达温停机信号时，获取第一检测温度和第一室内温度。
室内机的回风口处设置有温度检测装置，检测回风口的回风温度，用作室内机检测的室内温度。在该检测温度满足达温停机条件后，发出室内机达温停机信号。在收到该室内机达温停机信号时，将获取第一检测温度和第一室内温度。
其第一室内温度，为室内机中设置的温度检测装置所检测获取的、反映室内温度的温度。
第一检测温度为反映室内机所在房间内人体感知温度的温度。人体感知温度，为人体能够直接感受到的温度，一般为房间内人体活动范围的温度，如房间中下部的温度。第一检测温度可通过置于房间内人体活动范围内的温度检测装置检测，该实施例对第一检测温度的获取方式不作限定。例如，通过在室内机的遥控器内置温度检测装置检测获取；或者，通过在房间一定高度处设置温度检测装置检测获取，该一定高度为低于室内机安装高度且一般低于人体正常身高的高度，例如，房间内1-1.5m的高度位置；或者，通过在房间地面上放置的其他电器设备上设置的温度检测装置检测获取。
步骤102：根据第一检测温度对第一室内温度进行修正，获得修正后室内温度。
多联机空调器的室内机所安装的房间结构、室内机在房间中的安装位置、室内机的安装方式等的不同，会影响室内机回风口所检测的温度与房间内人体实际感受温度之间的差异。通过第一检测温度对第一室内温度进行修正，使得获得的修正后室内温度能够克服室内机安装状态的差异造成人体感受温度的影响，进而提高基于修正后室内温度进行其他控制的判断与执行的准确性。
根据第一检测温度修正第一室内温度的修正方式，该实施例不作限定，只要使得修正后室内温度能够克服室内机安装状态的差异造成人体感受温度的影响的所有修正方式，均属于本发明的保护范畴。
步骤103：在修正后室内温度满足预设吹余热时间修正条件时，执行确定修正后吹余热时间的过程。
预设吹余热时间修正条件作为对是否执行吹余热时间修正的判断条件，为已知的条件，可为固定不变的条件，也可为动态可变的条件。
在一些实施例中，预设吹余热时间修正条件为：修正后室内温度大于设定温度。设定温度为室内机的运行的当前设定温度，为已知值。
确定修正后吹余热时间的过程采用下述步骤104至步骤106来实现。
步骤104：将满足预设吹余热时间修正条件时的时刻作为计时开始时间，开始计时；在计时过程中，实时获取第二检测温度、第二室内温度和内盘管温度。
第二检测温度与第一检测温度类似，为反映室内机所在房间内人体感知温度的温度，检测手段同第一检测温度。
第二室内温度与第一室内温度类似，为室内机中设置的温度检测装置所检测获取的、反映室内温度的温度。
内盘管温度，为室内机换热器的盘管温度，可通过室内机换热器上的盘温检测装置检测取得。
步骤105：确定第一计时时间、第二计时时间和第三计时时间。
将从计时开始时间至第二室内温度与第二检测温度之差满足第一温差条件、且内盘管温度满足预设盘温条件时的时间，确定为第一计时时间。
将从计时开始时间至第二室内温度与第二检测温度之差满足第二温差条件、且内盘管温度不满足预设盘温条件时的时间，确定为第二计时时间。
将从计时开始时间至第二室内温度与第二检测温度之差满足第三温差条件时的时间，确定为第三计时时间。
而且，第二计时时间大于第一计时时间，第三计时时间大于第二计时时间。
对于多联机空调器，室内机达温停机后，室内机所检测的室内温度经历先升高再降低的过程，内盘管温度则逐渐降低。可基于室内机的该特性，确定各温差条件及盘温条件。
在一些实施例中，第一温差条件包括：第二室内温度低于第二检测温度，且两个温度之差不小于第一温差阈值。在其他一些实施例中，第一温差阈值为0.5℃，则在第二室内温度低于第二检测温度至少0.5℃时，判定满足了第一温差条件。
在一些实施例中，预设盘温条件包括：内盘管温度大于盘温阈值。在其他一些实施例中，盘温阈值为20℃，则在内盘管温度大于20℃时，判定内盘管温度满足预设盘温条件；若内盘管温度小于等于20℃，判定内盘管温度不满足预设盘温条件。
在一些实施例中，第二温差条件包括：第二室内温度高于第二检测温度，且第二室内温度与第二检测温度之差不小于第二温差阈值。在其他一些实施例中，第二温差阈值为0.3℃，则在第二室内温度高于第二检测温度至少0.3℃时，判定满足了第二温差条件。
在一些实施例中，第三温差条件包括：第二室内温度低于第二检测温度，且两个温度之差不小于第三温差阈值。在其他一些实施例中，第三温差阈值为0.5℃，则在第二室内温度低于第二检测温度至少0.5℃时，判定满足了第三温差条件。
步骤106：在第三计时时间和第二计时时间之差满足预设时间条件时，确定第三计时时间为修正后吹余热时间；否则，确定第一计时时间为修正后吹余热时间。
预设时间条件作为确定修正后吹余热时间的条件参量，为已知的条件，可为固定不变的条件，也可为动态可变的条件。在一些实施例中，预设时间条件包括：时间之差大于时间差阈值。在其他一些实施例中，时间差阈值为10S。则，若第三计时时间和第二计时时间之差大于10S，判定满足了预设时间条件。
在满足了预设时间条件时，表明室内机所在的房间换热不均匀，确定较长的第三计时时间为修正后吹余热时间，控制室内机吹余热时间更长，避免出现后续达温不启动的问题。若不满足预设时间条件，表明室内机所在的房间换热较为均匀，确定较短的第一计时时间为修正后吹余热时间，避免出现吹冷风而造成室内温度不舒适。
该实施例提供的多联机空调器的控制方法，利用反映房间内人体感知温度的检测温度修正室内温度，将修正后室内温度作为是否执行吹余热时间修正的判断参量，决定是否执行吹余热时间的修正；在修正吹余热时间时，基于房间内人体感知温度与室内机检测温度以及室内机的内盘管温度确定计时时间，进一步根据计时时间确定修正吹余热时间，使得吹余热时间自适应空调器的室内机所安装的房间结构、室内机在房间中的安装位置等安装状态，提高了吹余热时间的准确性，有效解决了因室内机安装状态的差异造成吹余热时间不准确而产生的室内机达温不启动和达温吹冷风等的问题，提高了基于吹余热时间控制空调器的准确性和使用舒适性，实现了智能空调器功能。
在其他一些实施例中，多联机空调器的控制方法还包括：
在修正后室内温度满足预设吹余热时间修正条件后，控制室内机的风机以第一预设转速运行，还同时控制室内机的导风板处于非吹人位置，例如，为水平位置；在第二室内温度与第二检测温度之差满足第一温差条件、且内盘管温度满足预设盘温条件后，控制室内机的风机以第二预设转速运行。其中，第二预设转速小于第一预设转速。在一些实施例中，第一预设转速为室内机的微弱风转速，第二预设转速为室内机的最低转速。
在所第二室内温度与第二检测温度之差满足第二温差条件、且内盘管温度不满足预设盘温条件后，控制室内机的风机停止。
图2示出了本发明多联机空调器的控制方法第二个实施例的流程示意图，具体来说，是确定室内机制热运行时的吹余热时间的一个实施例的流程示意图。其中，多联机空调器包括室外机和多个室内机，该实施例的控制方法是针对其中一个室内机而言。
如图2所示意，该实施例的控制方法采用下述过程实现。
步骤201：收到室内机达温停机信号时，获取第一检测温度和第一室内温度，获得修正后室内温度。
修正后室内温度的获取方式，参见图1实施例相应过程的描述。
步骤202：判断修正后室内温度是否满足预设吹余热时间修正条件。若是，执行步骤204；否则，执行步骤203。
预设吹余热时间修正条件的设置及判断过程，参见图1实施例相应过程的描述。
步骤203：控制室内机执行防冷风控制或者控制室内机运行状态保持。
若修正后室内温度不满足预设吹余热时间修正条件，不执行吹余热时间修正过程，而是控制室内机执行防冷风控制或者控制室内机运行状态保持。
若预设吹余热时间修正条件包括：修正后室内温度大于设定温度。则，若修正后室内温度不满足预设吹余热时间修正条件，则为修正后室内温度不大于设定温度。此状态下，在修正后室内温度小于设定温度时，控制室内机执行防冷风控制，以升高室内机盘管温度；在修正后室内温度等于设定温度时，控制室内机运行状态保持，也即，保持其当前运行状态不变化。
步骤204：判断是否存在修正后吹余热时间。若存在，转至步骤208；否则，执行步骤205。
若步骤202判定修正后室内温度满足了预设吹余热时间修正条件，则进一步判断是否存在该室内机的修正后吹余热时间，并根据判断结果执行不同的控制。
步骤205：判断收到的达温停机信号是否满足预设达温停机信号条件。若是，执行步骤207；若否，执行步骤206。
若步骤204判定不存在该室内机的修正后吹余热时间，将进一步判断收到的达温停机信号是否满足预设达温停机信号条件。
预设达温停机信号条件作为是否执行修正吹余热时间的判断条件，为已知条件。在一些实施例中，预设达温停机信号条件包括：为室内机上电开机后第二次收到达温停机信号。
步骤206：获取初始吹余热时间。
若步骤205判定收到的达温停机信号不满足预设达温停机信号条件，则不执行吹余热时间的修正，而是获取初始吹余热时间，利用初始吹余热时间执行吹余热控制。初始吹余热时间为已知的时间。
在预设达温停机信号条件为室内机上电开机后第二次收到达温停机信号时，若判断当前为上电开机后第一次收到达温停机信号，则不进行吹余热时间的修正，而是利用初始吹余热时间进行吹余热控制，避免室内机运行时间过短、室内房间温度不够均匀而造成室内机的过快启动所带来的空调器系统运行不稳定等的问题。
步骤207：执行确定修正后吹余热时间的过程。
若步骤205判定收到的达温停机信号满足预设达温停机信号条件，将执行确定修正后吹余热时间的过程，具体确定过程参见图1实施例的相应描述。而且，保存所确定的修正后吹余热时间，以供下次达温停机时直接调用。
步骤208：获取修正后吹余热时间。
该步骤根据步骤204的判断结果而执行。具体的，若步骤204判定存在该室内机的修正后吹余热时间，则不再执行达温停机信号是否满足预设达温停机信号条件的判断以及修正吹余热时间的调整的过程，而是将直接调用已经存在的修正后吹余热时间作为达温停机吹余热时间。
在该实施例中，结合多联机空调器中的室内机在安装后安装状态确定，基本不会发生变化的特点，对于一个固定的室内机，只需执行一次吹余热时间自适应安装状态的调整过程即可，调整后的修正吹余热时间保存，供后续达温停机时自动调用。并且，并非在室内机上电后的第一个达温停机循环中立即执行吹余热时间的修正，而是采用第二个达温停机循环或者满足其他预设达温停机信号条件下再执行修正，避免吹余热时间修正不精确，造成空调器系统运行不稳定、房间温度不舒适等问题的发生。
