Description

吸风式空调器的控制方法 技术领域
本发明属于空调技术领域，具体涉及一种吸风式空调器的控制方法。
背景技术
现有吸风式空调器大多都设置有用于安装和保护各种电控模块的电控箱，由于受到其室内机的内部结构限制，现有吸风式空调器的电控箱都设置在靠近室内风机的一侧，因而导致电控箱不断与换热后的空气接触。同时，又由于电控箱中的各个电控模块在工作过程中均会不断产生热量，因而现有电控箱通常都设置有散热构件以更好地将箱体内部的热量传导至箱体外部。当吸风式空调器运行制冷模式时，这些散热构件不仅能将箱体内部的热量传导出去，而且还能够吸收室内换热器产生的冷量。如果散热构件从外部吸收的冷量大于其正在传导的热量就会导致散热构件的温度降低，而当散热构件的温度不断降低时，散热构件暴露在箱体内部的部分就很容易出现凝露，凝露的不断聚集将会导致箱体内部的湿度不断提升，甚至还会在箱体内部聚集出水；在这种高湿环境下，设置在电控箱中的电控模块工作时很容易出现故障，甚至还会直接导致短路烧毁的问题。

首先参阅图1，该图是本发明的室内机的内部结构示意图。本发明的吸风式空调器包括通过冷媒管路相连的室内机和室外机(图中未示出)，其中，所述室内机中设置有室内换热器11，所述室外机中设置有室外换热器、变频压缩机和节流构件，室内换热器11、室外换热器、变频压缩机和节流构件通过冷媒管路相连，以使冷媒能够循环流动而实现换热。需要说明的是，本发明不对所述室内机和所述室外机的具体结构作任何限制，技术人员可以根据实际使用需求自行设定，只要所述空调器的类型为吸风式空调器即可。如图1所示，所述室内机中还设置有室内风机12和电控箱13，室内换热器11和室内风机12沿出风方向(箭头所指的方向)依次设置，电控箱13设置在靠近室内风机12的一侧，具体设置在图中的左下侧；当然，这并不是限制的设置位置，技术人员也可以根据实际使用需求自行调整电控箱13 的具体设置位置。进一步地，电控箱13中设置有各种电控模块，并且电控箱13上还设置有散热构件131，在本优选实施例中，散热构件131为金属散热片结构，其设置在电控箱13的上侧，用以充当电控箱13的上盖，以便有效提升散热效果。此外，还需要说明的是，本发明不对散热构件131的具体结构和设置位置作任何限制，技术人员可以根据实际使用需求自行设定，只要散热构件131设置在电控箱13上且能辅助电控箱13散热即可。

接着参阅图2，该图是本发明的控制方法的主要步骤流程图。如图2所示，基于上述优选实施例中所述的吸风式空调器，本发明的控制方法主要包括下列步骤：
S1：在空调器运行制冷工况的情形下，获取散热构件的温度和电控箱的内部温度；
S2：根据散热构件的温度和电控箱的内部温度，选择性地调节室内风机的转速和/或变频压缩机的频率。
在步骤S1中，在所述吸风式空调器运行制冷工况的情形下，所述控制器能够通过所述散热温度传感器获取散热构件131的温度且通过所述箱体温度传感器获取电控箱13的内部温度。需要说明的是，本发明中所述的制冷工况不仅局限于所述吸风式空调器执行制冷 模式的情形，还可以包括所述吸风式空调器执行室外除霜模式的情形等，即只要室内换热器11用作蒸发器的模式均属于本发明中所述的制冷工况。
在步骤S2中，所述控制器能够根据散热构件131的温度和电控箱13的内部温度选择性地调节室内风机12的转速和/或所述变频压缩机的频率。具体地，所述控制器既可以根据散热构件131的温度和电控箱13的内部温度是否处于预设温度范围内来选择性地调节室内风机12的转速和/或所述变频压缩机的频率，也可以根据散热构件131的温度和电控箱13的内部温度的比值或差值与预设值的比较结果来选择性地调节室内风机12的转速和/或所述变频压缩机的频率，这都不是限制性的，技术人员可以根据实际使用需求自行设定，只要判断条件中涉及的基础参数是散热构件131的温度和电控箱13的内部温度就属于本发明的保护范围。这些改变均不偏离本发明的基本原理，属于本发明的保护范围。
下面参阅图3，该图是本发明的控制方法的优选实施例的步骤流程图。如图3所示，基于上述优选实施例中所述的吸风式空调器，本发明的控制方法的优选实施例具体包括下列步骤：
S101：在空调器运行制冷工况的情形下，获取散热构件的温度和电控箱的内部温度；
S102：计算散热构件的温度与电控箱的内部温度的差值；
S103：判断差值是否大于预设差值；如果是，执行步骤S104；如果否，执行步骤S105；
S104：不根据散热构件的温度和电控箱的内部温度调节室内风机的转速和变频压缩机的频率；
S105：判断差值是否等于预设差值；如果是，执行步骤S106；如果否，执行步骤S107；
S106：增大室内风机的转速且控制变频压缩机的频率不得增大；
S107：增大室内风机的转速且降低变频压缩机的频率；
S108：经过预设时间后，再次获取散热构件的温度和电控箱的内部温度。
在步骤S101中，在所述吸风式空调器运行制冷工况的情形下，所述控制器能够通过所述散热温度传感器获取散热构件131的温度且通过所述箱体温度传感器获取电控箱13的内部温度。需要说明的是，本发明中所述的散热构件131的温度既可以是散热构件131上某点的温度，也可以是多点温度的平均值；同理，电控箱13的内部温度既可以是电控箱13内某点的温度，也可以是多点温度的平均值，技术人员可以根据实际使用需求自行设定。
接着，在步骤S102中，所述控制器能够计算散热构件131的温度与电控箱13的内部温度的差值，以便据此来判断散热构件131上出现凝露的概率。可以理解的是，这个计算工作既可以由所述控制器自行完成，也可以由单独的计算模块完成后再由所述控制器获取得到，这并不是限制性的；并且，虽然本优选实施例中使用的判断条件是将散热构件131的温度与电控箱13的内部温度的差值与预设差值进行比较，但这并不是限制性的，技术人员也可以将散热构件131的温度和电控箱13的内部温度分别与预设值进行比较，或者将散热构件131的温度与电控箱13的内部温度的比值与预设比值进行比较。这些具体判断条件的调整均不偏离本发明的基本原理，属于本发明的保护范围。此外，还需要说明的是，本发明不对所述预设差值的具体值作任何限制，技术人员可以根据实际使用需求自行设定；优选地，所述预设差值为零，以便有效均衡防凝露效果和制冷效果。
基于步骤S103的判断结果，如果所述控制器判断出散热构件131的温度与电控箱13的内部温度的差值大于所述预设差值，即散热构件131的温度大于电控箱13的内部温度，在此情形下，散热构件131以将电控箱13内部的热量传导至外部的换热过程为主，其从外部吸收的冷量小于其正在传导的热量，散热构件131没有产生凝露的风险；相应执行步骤S104，即所述控制器不根据散热构件131的温度和电控箱13的内部温度调节室内风机12的转速和所述变频压缩机的频率。换言之，所述控制器可以根据其他控制逻辑的控制结果自由调节室内风机12的转速和所述变频压缩机的频率，以便有效保证所述吸风式空调器的制冷效果，进而有效提升用户体验；当然，本发明不对其他控制逻辑的控制方式作任何限制。
基于步骤S105的判断结果，如果所述控制器判断出散热构件131的温度与电控箱13的内部温度的差值等于所述预设差值，即散热构件131的温度与电控箱13的内部温度相近甚至相同，在此情形下，散热构件131从外部吸收的冷量与其正在传导的热量相当，一旦散热构件131的温度继续下降，散热构件131就将面临表面产生凝露的风险；因而执行步骤S106，即所述控制器控制室内风机12的转速增大且控制所述变频压缩机的频率不得增大，以使散热构件131的温度得以小幅提升，进而有效降低凝露风险。具体而言，控制所述变频压缩机的频率不得增大的方式具体为：当其他控制逻辑需要控制所述变频压缩机的频率增大时，所述控制器不下达增大指令，以便有效控制所述变频压缩机的频率不再增大，当然，控制所述变频压缩机的频率减小的控制逻辑可以正常执行。此外，需要说明的是，本发明不对室内风机12的转速的增大量作具体限制，技术人员可以根据实际情况自行设定；作为一种优选的调节方式，对于有极调节的室内风机12，控制室内风机12的转速提升一个档位。
进一步地，如果步骤S103和步骤S105的判断结果均为否，则说明散热构件131的温度与电控箱13的内部温度的差值小于所述预设差值，即散热构件131的温度小于电控箱13的内部温度，在此情形下，散热构件131以吸收外部冷量的换热过程为主，其从外部吸收的冷量大于其正在传导的热量，散热构件131正在面临凝露风险，执行步骤S107，即所述控制器控制室内风机12的转速增大且控制所述变频压缩机的频率降低，以便快速提升散热构件131的温度，从而有效避免散热构件131的表面产生凝露，进而有效避免设置在电控箱13中的电控模块出现短路甚至烧毁的问题。需要说明的是，本发明不对步骤S103和步骤S105的执行顺序作任何限制，技术人员可以根据实际情况自行调整，例如，也可以先执行步骤S105对应的判断条件再执行步骤S103对应的判断条件。这种有关具体执行顺序的调整并不偏离本发明的基本原理，属于本发明的保护范围。
作为一种优选控制方式，所述控制器控制室内风机12的转速增大预设转速且控制所述变频压缩机的频率降低预设频率，对于有极调节的室内风机12，所述预设转速为控制室内风机12的档位提升 一个档位时对应提升的转速，所述预设频率优选为10Hz；即，所述控制器控制室内风机12提升一个档位且控制所述变频压缩机的频率降低10Hz。当然，这仅是一种优选调节方式，但并不是限制性的，技术人员也可以根据实际使用需求自行调节。
在执行完步骤S107后，接着，在步骤S108中，经过所述预设时间后，所述控制器能够再次获取散热构件131的温度和电控箱13的内部温度，以便及时判断散热构件131的温度是否已经得到快速提升，从而最大程度地避免散热构件131的表面产生凝露的风险。在获取到散热构件131的温度和电控箱13的内部温度之后，再次执行S102，以便再一次对散热构件131产生凝露的风险进行全面分析，并根据分析结果执行相应步骤，进而有效保护电控模块的安全。需要说明的是，本发明不对所述预设时间的具体值作任何限制，技术人员可以根据实际使用需求自行设定；优选地，所述预设时间为5分钟，以便有效避免频繁操作所带来的能量损耗，进而在保护电控模块的同时，还能够有效兼顾所述吸风式空调器的换热效率。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不仅局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
