图2是本申请提供的空调器压缩机频率调节的装置的结构示意图;
图3是本申请提供的电子设备的结构示意图。
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。
本申请的说明书和权利要求书中的术语“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中,除非另有说明,“多个”的含义是两个或两个以上。
下面结合图1-图3描述本申请的空调器压缩机频率调节的控制方法、装置、电子设备及存储介质。
对于变频空调,电脑板程序通常会将室外环境温度与压缩机频率一一对应,当室外环境温度达到某一个值的时候,空调器室外机温度传感器会将温度值转变成数字信号传到室外机电脑板中,控制系统锁定压缩机频率。但是这种调频方式的缺点是:当两个相邻频率点互相切换时,若是此时的环境温度剧烈变化,比如说,环境温度升温速率达到0.02℃/s时,空调器在超过48℃时本应该开始降频,但是,为了防止压缩机频率波动太频繁,影响压缩机性能,在程序接收温度数字信号并计算后,会在两分钟后才发出降频指令,控制压缩机降频工作。当压缩机开始降频的时候,环境温度已经上升到50.4℃,此时,压缩机排气温度需要超过51℃才能实现换热,而相应排气压力已经达到3.2MPa,或者更高。在压缩机高频时,为达到高压力,压缩机输入电流会相应升高很多,峰值经常超过IPM安全电流或者电源安全电流,从而导致压缩机停机。
降低压缩机频率可以让压缩机平稳运行,但是如果压缩机一直在低频运 行,空调制冷量也会相应降低,导致室内温度迟迟无法下降。基于此,本申请提供一种空调器压缩机频率调节的控制方法,用于解决以上问题。
如图1所示,在本申请的一个实施例中,空调器压缩机频率调节的控制方法,具体包括以下步骤:
步骤101:实时获取室外环境的升温速率。
具体来说,空调器室外机上设置有温度传感器,温度传感器可以实时检测室外的环境温度,进而可以计算出室外环境的实际升温速率。
步骤102:判断实际升温速率是否达到目标升温速率;步骤103:若实际升温速率小于目标升温速率,根据室外环境温度控制压缩机的运行频率;若实际升温速率等于或大于目标升温速率,控制压缩机在调整时间内降低至最低频率,并保持该最低频率运行;其中,调整时间为20-30s。
具体来说,在室外环境的实际升温速率小于目标升温速率时,压缩机根据室外环境温度自动调节自身的频率,使压缩机处于稳定运行状态;在室外环境的实际升温速率等于或大于目标升温速率时,控制压缩机在较短的时间内降低至最低频率,并以最低频率运行。
进一步地,在本申请的一个实施例中,目标升温速率可以为0.01℃/s,调整时间为一个比较短暂的时间,如20-30s,当室外环境的升温速率等于或大于0.01℃/s,控制压缩机在20-30s内降低至最低频率,如压缩机的最低频率为35Hz,则压缩机保持35Hz的频率运行。在压缩机以最低频率运行过程中,室外机的温度传感器依然会检测室外的环境温度,若获取到的室外环境的实际升温速率小于0.01℃/s时,压缩机会根据室外环境温度自动调节自身的频率,按照与室外环境温度对应的频率工作。
可以理解的是:在压缩机按照与室外环境温度对应的频率工作时,若室外环境温度再次发生变化,如获取到的实际升温速率再次大于目标升温速率,则压缩机会再次在调整时间内降频至最低频率,并保持该最低频率运行。
在本申请的实施例中,当获取到的室外环境升温速率等于或大于0.01℃/s时,压缩机会在极短的时间内降低至最低频率,由于该降频的时间较短,压缩机排气的滞后时间也短,排气温度会在较短的时间内出现下降,排气压力也会下降,从而可以保证压缩机稳定运行,而不会发生停机。
本申请实施例提供的空调器压缩机频率调节的控制方法,在室外环境温 度升温速率较快时,控制压缩机在较短时间内降低至最低频率工作,缩短压缩机排气的滞后时间,使压缩机排气温度在较短时间内出现下降,从而降低排气压力,保证压缩机稳定运行,而不会发生停机事件。
进一步地,在本申请的一个实施例中,实时获取室外环境的实际升温速率的步骤进一步包括:实时获取室外环境温度,基于该室外环境温度确定室外环境的实际升温速率。
具体来说,在室外机设置温度传感器,温度传感器可以实时采集室外环境温度,根据室外环境温度的变化可以计算出单位时间内室外环境的升温速率,即室外环境的实际升温速率。
进一步地,在本申请的一个实施例中,在判断实际升温速率是否达到目标升温速率的步骤之前还包括:获取目标升温速率,其中,目标升温速率为0.01℃/s。
具体来说,在本实施例中,为了减少室外环境快速升温对压缩机造成的影响,将升温速率的单位设定为℃/s,即在外部环境发生变化时,能够快速检测到环境温度的变化。进一步地,根据实验结果将目标升温速率设置为0.01℃/s,当然,对于一些特殊环境,目标升温速率也可以更快,如0.015℃/s。
在本申请的一个实施例中,空调器压缩机频率调节的控制方法还包括:在压缩机保持最低频率运行的过程中,控制室外风机增大转速。
具体来说,在压缩机以最低频率运行的过程中,可提高室外风机的转速,以加强换热,使冷凝器内冷媒的温度降低,从而降低压缩机的排气温度和排气压力。具体地,如将室外风机的转速由正常转速提高至960rpm。通常来说,室外风机的正常转速为840rpm。
进一步地,在本申请的一个实施例中,空调器压缩机频率调节的控制方法还包括:在增大室外风机的转速后,当压缩机稳定运行预设时间后,控制室外风机减小转速。
具体来说,在增大室外风机的转速后,当压缩机稳定运行预设时间后,可减小室外风机的转速,使室外风机的转速降低至正常转速,如降低至840rpm。可选地,在本申请的一个实施例中,预设时间为1分钟。

具体来说,第一获取模块201可获取室外环境的实际升温速率信息,并将该实际升温速率信息发送至判断模块202,判断模块202将该实际升温速率与预设的目标升温速率进行比较,并将比较结果发送至第一控制模块203,第一控制模块203根据比较结果,控制压缩机按照相应的策略运行。
