Abstract

提供了一种变频空调主动控制方法及装置。该控制方法包括：开启变频压缩机使得变频压缩机在第一频率下运行第一时长，对智能功率模块IPM的温度进行检测，在智能功率模块IPM的温度未超过阈值的情况下，检测室外盘管的温度，根据室外盘管的温度所属的温度区间决定是否对第一频率进行调整。若室外盘管温度相对较低，需要加大第一频率，使得变频空调的制冷能力提高，并且进一步对室外盘管的温度进行修正；若室外盘管温度相对较高，无需对第一频率进行调整，则检测排气压力。该控制方法实现了对变频空调的主动控制，达到了高温环境下保持变频空调的制冷能力不降低的目的。

Description

变频空调主动控制方法及装置 技术领域
本发明实施例涉及变频空调技术，尤其涉及一种变频空调主动控制方法及装置。
背景技术
相对于定速空调来说，变频空调采用了变频压缩机和控制装置，使得空调的压缩机的频率不是固定的，而是可以随着负荷的变化而变化，能够为用户提供更好的舒适度。
高温环境下，即温度高于50℃时，变频空调为输出更大的制冷能力，需要运行更大的频率。频率升高，导致变频空调的智能功率模块(Intelligent Power Module，IPM)的输出功率越大，发热量越大，导致IPM的温度越高，容易损坏IPM。另外，频率升高，导致变频压缩机运行在超高的排气压力下，长时间运行在超高的排气压力下，容易损坏变频压缩机且安全隐患高。为解决上述问题，目前的变频空调通过人为的限制变频压缩机的运行频率，使得IPM的输出功率较低，温度也相应的交底，同时使得排气压力相对较低。
上述变频空调控制过程中，通过人为限制变频压缩机的运行频率，导致变频空调的制冷能力下降，使用变频空调后，温度并没有下降到预期值。
发明内容

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本发明的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包 括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
图1为本发明变频空调主动控制方法实施例的流程图。本发明实施例的执行主体为变频空调主动控制装置，该装置设置在变频空调上。具体的，本发明实施例包括：
步骤1、启动变频压缩机，以使所述变频压缩机在第一频率下运行第一时长。
一般来说，可根据气候类型将环境分为三类：第一类、T1环境，该环境下最高温度为43℃；第二类、T2环境，该环境下最高气温为35℃；第三类、T3温度，该环境下最高气温为52℃。本发明实施例中的变频空调，主要用于T3环境。在T3环境下，开启变频空调，启动变频空调的变频压缩机，使得变频压缩机在第一频率下运行第一时长，运行第一时长后，室内温度趋于稳定。其中，第一频率例如为变频压缩机的初始频率，其一般为50HZ～55HZ。第一时长为一个预先设定的值，例如为5分钟。
步骤2、确定第一温度是否超过第一阈值，所述第一温度为智能功率模块IPM的温度，若未超过，则执行步骤3；否则，执行步骤8。
本发明实施例中，将智能功率模块(Intelligent Power Module，IPM)的温度称之为第一温度，将变频空调的室外盘管的温度称之为第二温度。本步骤中，采集IPM的第一温度，例如，在IPM上设置温度传感器，根据该温度传感器，检测出IPM的第一温度。采集到第一温度后，确定该第一温度是否超过第一阈值。若超过，则说明IPM的温度较高，继续在该温度下工作，可能会损耗IPM，此时需要执行步骤8以降低第一频率从而降低IPM的温度；若第一温度未超过第一阈值，则说明IPM的温度比较合适，在该温度下不会导致IPM损坏，继续执行步骤3。
步骤3、确定第二温度，根据所述第二温度所属的温度区间，确定是否需要调整所述第一频率，若需要，则执行步骤4；否则，执行步骤5，所述第二温度为室外盘管的温度。
具体的，在确定出第一温度未超过第一阈值后，继续确定室外判断的第二温度所属的温度区间，进而根据温度区间确定是否需要调整第一频率。其中，温度区间包括的温度由低至高被划分为连续的第一区间、第二 区级、第三区间与第四区间。本步骤中，确定室外判断的第二温度属于哪个区间，根所属的区间不同，接下来的执行动作也不同。若第二温度属于第一区间或第二区间则执行步骤4以对第一频率进行调整，调整后返回步骤2，第一频率的变化，导致第二温度也发生变化，因此可以实现对室外盘管的第二温度的修正。若第二温度属于第三区间或第四区间，则执行步骤5以对变频空调的排气压力进行检测。
步骤4、调整所述第一频率，将所述变频压缩机在调整后的频率下运行第一预设时长，返回步骤2。
具体的，若步骤3中，确定出第二温度属于第一区间，则步骤4具体为：将第一频率增加第一设定值得到第二频率，将变频压缩机在第二频率下运行第一预设时长，返回步骤2；
若步骤3中，确定第二温度属于第二区间，则步骤4具体为：将第一频率增加第二设定值得到第三频率，将变频压缩机在第三频率下运行第一预设时长，返回步骤2；
上述的当第二温度属于第一区间或第二区间时，增大第一频率，从而提高变频空调的制冷能力。
若步骤3中，确定第二温度属于第三区间或第四区间，则执行步骤5。
其中，所述第一区间中，所述第二温度≤62℃；所述第二区间中，60℃＜所述第二温度＜67℃；所述第三区间中，67℃＜所述第二温度＜70℃；所述第四区间中，所述第二温度≥70℃。所述第一设定值大于所述第二设定值。由此可知，当第二温度相对较低时，需要对第一频率进行调整；当第二温度相对较高时，需要确定排气压力。
步骤5、确定排气压力是否小于预设阈值，若小于，则执行步骤6；否则，执行步骤7。
步骤6、调整所述第一频率，运行第二预设时长后返回步骤2。
步骤7、关闭所述变频压缩机。
本发明实施例中，变频空调的排气管上安装有压力开关。步骤5中，通过压力开关实现压力检测。当排气压力小于预设阈值时，执行步骤6以降低第一频率，并在降低后的频率下运行第二预设时长；当排气压力大于预设阈值，说明排气管上的压力太大，有可能损坏排气管，此时执行步骤 7以关闭变频压缩机，即关闭变频空调。
步骤8、调整所述第一频率，运行第三预设时长后返回步骤2。
本发明实施例提供的变频空调主动控制方法，开启变频压缩机使得变频压缩机在第一频率下运行第一时长使得室内温度趋于温度后，对IPM的温度进行检测，在IPM的温度未超过阈值处于安全环境的情况下，检测出室外盘管的温度，根据室外盘管的温度所属的温度区间决定是否对第一频率进行调整，若室外盘管温度相对较低，需要加大第一频率，使得变频空调的制冷能力增加，并且进一步对室外盘管的温度进行修正；若室外盘管温度相对较高，无需对第一频率进行调整，则检测排气压力，从而实现对变频空调的主动控制，实现高温环境下不衰减变频空调的制冷能力的目的。
下面，用一个具体的实施例对本发明变频空调主动控制方法进行详细说明。具体的，可参见图2，图2为本发明变频空调主动控制方法实施例二的流程图。本实施例包括：

101、启动变频压缩机，以使所述变频压缩机在第一频率下运行第一时长。
本步骤中，开启变频空调，开始制冷，使得变频压缩机在第一频率下，如50～55HZ的频率下运行第一时长，如5分钟。
102、确定第一温度是否超过第一阈值，所述第一温度为智能功率模块IPM的温度，若未超过，则执行103；否则，执行112。
本实施例中，将第一阈值设置为90℃。本步骤中，检测室外的IPM的温度是否满足第一温度≤90℃的条件，若满足，则执行103；否则，执行112。
103、确定第二温度，根据第二温度所属的温度区间。
具体的，采集室外盘管的第二温度，根据第二温度以查表的方式，确 定该第二温度处于哪个区间。其中，温度区间包括的温度由低至高被划分为连续的第一区间、第二区级、第三区间与第四区间；第一区间中，第二温度≤62℃；第二区间中，60℃＜第二温度＜67℃；第三区间中，67℃＜第二温度＜70℃；第四区间中，第二温度≥70℃。若确定出第二温度属于第一区间，则执行104；若确定出第二温度属于第二区间，则执行105；若确定温度区间属于第三区间，则执行106；如确定出温度区间属于第四区间，则执行107；
104、将所述第一频率增加第一设定值得到第二频率，将所述变频压缩机在所述第二频率下运行所述第一预设时长。
具体的，第一设定值例如为5HZ，第一预设时长例如为1～10分钟。本步骤中，将第一频率调高后得到第二频率，在第二频率下运行1～10分钟，然后返回102。也就是说，当第二温度处于第一区间时，将第一频率增加，在增大的频率下运行1～10分钟后继续检测IPM的第一温度，在IPM的第一温度小于第一阈值时，继续采集室外盘管的第二温度，如果第二温度还是属于第一区间，则继续循环执行该过程，直到第二温度退出该第一区间，达到第二区间。
105、将所述第一频率增加第二设定值得到第三频率，将所述变频压缩机在所述第三频率下运行所述第一预设时长。
具体的，第二设定值例如为3HZ，第一预设时长例如为1～10分钟。本步骤中，将第一频率调高后得到第三频率，在第三频率下运行1～10分钟，然后返回102。也就是说，当第二温度处于第二区间时，将第一频率增加，在增大的频率下运行1～10分钟后继续检测IPM的第一温度，在IPM的第一温度小于第一阈值时，继续采集室外盘管的第二温度，如果第二温度还是属于第二区间，则继续循环执行该过程，直到第二温度退出该第二区间，达到第三区间。
106、保持第一频率运行，返回102；
本步骤中，将变频压缩机在第一频率下一直运行下去。
107、确定排气压力是否小于预设阈值，若小于，则执行108；否则，执行109；
本步骤中，需要检测排气压力，若排气压力≤4.8MPa，则执行108以 降低第一频率；否则，执行109以关闭变频空调。
108、将所述第一频率减少第三设定值得到第四频率，将所述变频压缩机在所述第四频率下运行所述第二预设时长，返回102。
具体的，第三设定值例如为3HZ，第二预设时长例如为1～10分钟。本步骤中，将第一频率降低后得到第四频率，在第四频率下运行1～10分钟，然后返回102。
