具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1所示，示出了本发明一种空调器控制方法第一实施例。该实施例的空调器控制方法包括：
步骤S10、侦测空调器是否接收到关机指令或者模式切换指令；
步骤S20、若所述空调器接收到关机指令或者模式切换指令，则控制所述空调器的压缩机停止工作，以及控制所述空调器的四通阀内部滑块延迟第一预设时间后执行换向动作，以削弱所述四通阀换向时两端的压差。
本实施例中，该空调器可包括室内机和室外机，该室内机内可设有室内换热器组件及电子膨胀阀；室外机内可设有压缩机、四通阀、室外换热器、低压储液罐、电磁阀、毛细管、室外机节流部件以及室外机节流部件等等。其中，压缩机、四通阀、室内换热器组件、室外换热器、室外节流部件之间通过管路连接，形成制冷/制热循环回路。
本实施例中，模式切换为制热模式、制冷模式、除湿模式、送风模式等两两模式之间的切换。当空调器接收到关机指令或者模式切换指令时，空调器室外机的压缩机停机。同时，空调器室外机的四通阀收到换向动作的指令，此时四通阀内部滑块延迟第一预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作。即四通阀收到换向动作的指令后，四通阀内部滑块保持当前动作状态，经过第一预设时间后四通阀断电，执行换向动作。由于空调工况的差异，该第一预设时间可设置为5秒～30秒，也可根据具体情况而灵活设置。从而使得在不影响用户正常使用情况下，在压缩机运行时延迟执行四通阀换向动作，减小了四通阀内部滑块两端的压差，滑块换向时冷媒冲击的声音也减小。当空调器没有接收到关机指令或者模式切换指令时，压缩机及四通阀维持当前的工作状态。
以下进行举例说明，假设空调器正常运行时，室外机噪音值为55.7分贝，空调器断电瞬间由于四通阀的换向，噪音值升高了10.1分贝，变为65.8分贝，噪音非常大，影响用户使用空调器的舒适性。而本实施例在空调器断电或进行模式切换时四通阀不立即换向，延迟10秒之后四通阀内部滑块才由当前移动方向往相反的方向移动，完成四通阀的换向动作，噪音值仅有1.1分贝的升高，变为11.2分贝，使得四通阀两端的压差减小，削弱了四通阀换向时引起噪音值的升高。
本发明实施例空调器在接收到关机指令或者模式切换指令后，控制压缩机停止工作，以及控制四通阀延迟第一预设时间执行换向动作。使得通过延迟四通阀执行换向动作的时间，削弱了四通阀换向时两端的压差，降低了四通阀换向时产生的噪音，提升了用户的满意度。同时，相对于通过检测四通阀换两端的压差来执行换向动作，降低了四通阀换向时降噪的成本。
进一步地，基于上述空调器控制方法第一实施例，提出了本发明空调器控制方法第二实施例，该实施例中当所述空调器的压缩机为变频压缩机时， 上述步骤S10之后包括：
若所述空调器接收到关机指令或者模式切换指令，则获取所述空调器的变频压缩机的运行频率，并控制所述变频压缩机停止工作；
当所述变频压缩机的运行频率小于预设运行频率值时，控制所述空调器的四通阀延迟第二预设时间后执行换向动作，所述第二预设时间小于第一预设时间。
本实施例中，当空调器的压缩机为变频压缩机时，空调器在接收到关机指令或者模式切换指令时，空调器室外机的四通阀接收到换向动作的指令，同时检测变频压缩机的运行频率，变频压缩机开始停止工作。此时空调器判断变频压缩机的运行频率是否小于预设运行频率值，该预设运行频率值可设置为为30Hz，也可根据具体情况而灵活设置。若变频压缩机的运行频率小于预设运行频率值，则四通阀根据接收到的换向动作的指令，四通阀内部滑块延迟第二预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作。该第二预设时间小于上述的第一预设时间，减短了变频压缩机停机之后，四通阀延迟换向动作的时间。若变频压缩机的运行频率大于或等于预设运行频率值，则四通阀根据接收到的换向动作的指令，四通阀内部滑块延迟第一预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作，该第一预设时间与上述提到的第一预设时间一致。
本实施例当空调器的压缩机为变频压缩机时，在空调器接收到关机指令或者模式切换指令后，根据变频压缩机的运行频率控制四通阀延迟执行换向动作的时间，并当变频压缩机的运行频率小于预设运行频率值时，缩短延迟时间。提高了四通阀延迟执行换向动作的可靠性，降低了四通阀换向时产生的噪音。
进一步地，基于上述空调器控制方法第一实施例，提出了本发明空调器控制方法第三实施例，该实施例中上述步骤S20包括：若所述空调器接收到关机指令或者模式切换指令，则控制所述空调器的压缩机停止工作，触发计时器开始计时；
当所述计时器的计时时间达到第一预设时间后，控制所述空调器的四通阀内部滑块执行换向动作。
本实施例中，空调器可包括计时器或者预置的计时模块，用于采集四通 阀延迟执行换向动作的时间。获取延迟时间的方式可包括：方式一，空调器在运行的过程中，当接收到关机指令或模式切换指令后，触发计时器开始计时，并在达到预设时间后向空调器反馈延迟时间。方式二，通过与空调器有连接关系的终端进行计时，该终端的类型可根据实际需要进行设置。例如，当空调器接收到关机指令或模式切换指令时，通过通信装置发送开始计时指令至终端，终端接收到空调器发送过来的开始计时指令后，进行计时。在延迟时间达到预设时间时停止计时，并返回延时时间至空调器，以使空调器根据返回的延时时间执行相应的操作。上述获取延迟时间的方式仅为具体实施方式的枚举，本领域技术人员提出的其它获取延迟时间的方式，均在本发明的保护范围内。
具体地，当空调器接收到关机指令或者模式切换指令时，空调器室外机的压缩机停机。同时，触发计时器开始计时，当计时器的计时时间达到第一预设时间后进行反馈，空调器室外机的四通阀收到换向动作的指令，此时四通阀内部滑块由当前移动方向往相反的方向移动，完成四通阀的换向动作。该第一预设时间与上述提到的预设时间一致。当空调器没有接收到关机指令或者模式切换指令时，压缩机及四通阀维持当前的工作状态。
本实施例空调器在接收到关机指令或者模式切换指令后，在不影响用户正常使用情况下，在压缩机运行时延迟执行四通阀换向动作，减小了四通阀内部滑块两端的压差，降低了四通阀换向时产生的噪音，提升了用户的满意度。

本实施例中，该空调器可包括室内机和室外机，该室内机内可设有室内换热器组件及电子膨胀阀；室外机内可设有压缩机、四通阀、室外换热器、低压储液罐、电磁阀、毛细管、室外机节流部件以及室外机节流部件等等。 其中，压缩机、四通阀、室内换热器组件、室外换热器、室外节流部件之间通过管路连接，形成制冷/制热循环回路。
本实施例中，模式切换为制热模式、制冷模式、除湿模式、送风模式等两两模式之间的切换。首先由侦测模块100侦测空调器是否接收到关机指令或者模式切换指令，当空调器接收到关机指令或者模式切换指令时，第一控制模块200控制空调器室外机的压缩机停机。同时，空调器室外机的四通阀收到换向动作的指令，此时第一控制模块200控制四通阀内部滑块延迟第一预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作。即四通阀收到换向动作的指令后，四通阀内部滑块保持当前动作状态，经过第一预设时间后四通阀断电，执行换向动作。由于空调工况的差异，该第一预设时间可设置为5秒～30秒，也可根据具体情况而灵活设置。从而使得在不影响用户正常使用情况下，在压缩机运行时延迟执行四通阀换向动作，减小了四通阀内部滑块两端的压差，滑块换向时冷媒冲击的声音也减小。当空调器没有接收到关机指令或者模式切换指令时，压缩机及四通阀维持当前的工作状态。
以下进行举例说明，假设空调器正常运行时，室外机噪音值为55.7分贝，空调器断电瞬间由于四通阀的换向，噪音值升高了10.1分贝，变为65.8分贝，噪音非常大，影响用户使用空调器的舒适性。而本实施例在空调器断电或进行模式切换时四通阀不立即换向，延迟10秒之后四通阀内部滑块才由当前移动方向往相反的方向移动，完成四通阀的换向动作，噪音值仅有1.1分贝的升高，变为11.2分贝，使得四通阀两端的压差减小，削弱了四通阀换向时引起噪音值的升高。
本发明实施例空调器在接收到关机指令或者模式切换指令后，控制压缩机停止工作，以及控制四通阀延迟第一预设时间执行换向动作。使得通过延迟四通阀执行换向动作的时间，削弱了四通阀换向时两端的压差，降低了四通阀换向时产生的噪音，提升了用户的满意度。同时，相对于通过检测四通阀换两端的压差来执行换向动作，降低了四通阀换向时降噪的成本。
进一步地，基于上述空调器控制装置第一实施例，提出了本发明空调器控制装置第二实施例，该实施例中当所述空调器的压缩机为变频压缩机时，上述空调器控制装置还包括：
第二控制模块，用于若所述空调器接收到关机指令或者模式切换指令，则获取所述空调器的变频压缩机的运行频率，并控制所述变频压缩机停止工作；当所述变频压缩机的运行频率小于预设运行频率值时，控制所述空调器的四通阀内部滑块延迟第二预设时间后执行换向动作，所述第二预设时间小于第一预设时间。
本实施例中，当空调器的压缩机为变频压缩机时，空调器在接收到关机指令或者模式切换指令时，空调器室外机的四通阀接收到换向动作的指令，同时第二控制模块检测变频压缩机的运行频率，变频压缩机开始停止工作。此时第二控制模块判断变频压缩机的运行频率是否小于预设运行频率值，该预设运行频率值可设置为为30Hz，也可根据具体情况而灵活设置。若变频压缩机的运行频率小于预设运行频率值，则第二控制模块控制四通阀根据接收到的换向动作的指令，四通阀内部滑块延迟第二预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作。该第二预设时间小于上述的第一预设时间，减短了变频压缩机停机之后，四通阀延迟换向动作的时间。若变频压缩机的运行频率大于或等于预设运行频率值，则四通阀根据接收到的换向动作的指令，四通阀内部滑块延迟第一预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作，该第一预设时间与上述提到的第一预设时间一致。
本实施例当空调器的压缩机为变频压缩机时，在空调器接收到关机指令或者模式切换指令后，根据变频压缩机的运行频率控制四通阀延迟执行换向动作的时间，并当变频压缩机的运行频率小于预设运行频率值时，缩短延迟时间。提高了四通阀延迟执行换向动作的可靠性，降低了四通阀换向时产生的噪音。
进一步地，基于上述空调器控制装置第一实施例，提出了本发明空调器控制装置第三实施例，该实施例中上述第一控制模块200包括：
计时单元，用于若所述空调器接收到关机指令或者模式切换指令，则控制所述空调器的压缩机停止工作，触发计时器开始计时；
控制单元，用于当所述计时器的计时时间达到第一预设时间后，控制所述空调器的四通阀内部滑块执行换向动作。
本实施例中，空调器可包括计时器或者预置的计时模块，用于采集四通阀延迟执行换向动作的时间。获取延迟时间的方式可包括：方式一，空调器在运行的过程中，当接收到关机指令或模式切换指令后，触发计时器开始计时，并在达到预设时间后向空调器反馈延迟时间。方式二，通过与空调器有连接关系的终端进行计时，该终端的类型可根据实际需要进行设置。例如，当空调器接收到关机指令或模式切换指令时，通过通信装置发送开始计时指令至终端，终端接收到空调器发送过来的开始计时指令后，进行计时。在延迟时间达到预设时间时停止计时，并返回延时时间至空调器，以使空调器根据返回的延时时间执行相应的操作。上述获取延迟时间的方式仅为具体实施方式的枚举，本领域技术人员提出的其它获取延迟时间的方式，均在本发明的保护范围内。
具体地，当空调器接收到关机指令或者模式切换指令时，空调器室外机的压缩机停机。同时，计时单元触发计时器开始计时，当计时器的计时时间达到第一预设时间后进行反馈，空调器室外机的四通阀收到换向动作的指令，此时控制单元控制四通阀内部滑块由当前移动方向往相反的方向移动，完成四通阀的换向动作。该第一预设时间与上述提到的预设时间一致。当空调器没有接收到关机指令或者模式切换指令时，压缩机及四通阀维持当前的工作状态。
本实施例空调器在接收到关机指令或者模式切换指令后，在不影响用户正常使用情况下，在压缩机运行时延迟执行四通阀换向动作，减小了四通阀内部滑块两端的压差，降低了四通阀换向时产生的噪音，提升了用户的满意度。
如图3所示，示出了本发明一种空调器控制方法第一实施例。该实施例的空调器控制方法包括：
步骤S310、侦测空调器的四通阀是否接收到换向指令；
步骤S320、若所述空调器的四通阀接收到换向指令，则检测所述空调器的压缩机的运行频率；
本实施例中，该空调器可包括室内机和室外机，该室内机内可设有室内换热器组件及电子膨胀阀；室外机内可设有压缩机、四通阀、室外换热器、低压储液罐、电磁阀、毛细管、室外机节流部件以及室外机节流部件等等。 其中，压缩机、四通阀、室内换热器组件、室外换热器、室外节流部件之间通过管路连接，形成制冷/制热循环回路。
本实施例中，空调器监听四通阀是否接收到换向指令，例如，空调器进行制热模式、制冷模式、除湿模式、送风模式等两两模式之间的切换，或者进行关机时，四通阀将会接收到换向指令。当空调器的四通阀接收到换向指令时，检测空调器的压缩机的运行频率，以便根据压缩机的运行频率判定是否需要先降低压缩机的运行频率再执行四通阀换向动作。可选地，空调器也可以侦测四通阀是否接收到断电指令或通电指令，当四通阀接收到断电指令或通电指令时，说明四通阀接收到换向指令，即该换向指令包括断电指令和通电指令。当空调器的四通阀没有接收到换向指令时，空调器维持当前的运行状态。
步骤S330、根据所述压缩机的运行频率与预设频率之间的大小关系，对所述压缩机的运行频率进行调节；
本实施例中，在检测得到压缩机的运行频率后，将压缩机的运行频率与预设频率进行比较，判断压缩机的运行频率大于预设频率。当压缩机的运行频率大于预设频率时，将压缩机的运行频率降低预设值，该预设值可根据压缩机的运行频率进行设置。在对压缩机的运行频率进行降低后，延迟预设时间，等待压缩机的运行频率稳定后，再执行四通阀的换向动作。该预设时间可设置为5秒钟，或者根据实际情况进行设置。当压缩机的运行频率小于或等于预设频率时，对压缩机的运行频率进行调节的幅度为零，即压缩机维持当前的运行频率。该预设频率可设置为30Hz～40Hz，也可根据具体情况而灵活设置。
步骤S340、控制所述四通阀内部滑块执行换向动作，以削弱所述四通阀换向时两端的压差。
当上述对压缩机的运行频率进行调节后，保证压缩机的运行频率小于或等于预设频率，此时可控制四通阀执行换向动作。具体地，四通阀内部滑块由当前移动方向往相反的方向移动，完成四通阀的换向动作。即四通阀在收到换向指令时，同时检测压缩机的运行频率，根据检测得到的运行频率进行调节后再执行四通阀换向动作。从而使得在不影响用户正常使用情况下，在压缩机运行时，当运行频率高于预设频率时将运行频率降低后，四通阀内部 滑块两端的压差减小，滑块换向时冷媒冲击的声音减弱。
以下进行举例说明，假设空调器正常运行时，空调器的压缩机按照30Hz的运行频率正常运行时，室外机产生的噪音值为55.3分贝，空调器断电瞬间由于四通阀的换向，产生的噪音值有63分贝。而当压缩机按照70Hz的运行频率正常运行时，室外机产生的噪音值为57.3分贝，断电瞬间由于四通阀的换向，产生的噪音值有70.3分贝，该噪音非常大，影响用户使用空调器的舒适性。通过对比可知，当四通阀需执行换向动作时，将压缩机的运行频率降低，有助于降低室外机产生的噪音，提高用户使用空调的舒适度。因此，假设将预设频率设置为30Hz，空调器在运行的过程中，当四通阀接收到换向指令时，检测得到压缩机的运行频率为80Hz，大于预设频率，此时，可将压缩机的运行频率降低至30Hz，然后再控制四通阀内部滑块由当前移动方向往相反的方向移动，完成四通阀的换向动作，削弱了四通阀换向时两端的压差，降低了噪音。
本发明实施例空调器的四通阀在接收到换向指令后，根据压缩机的运行频率与预设频率之间的大小关系对压缩机的运行频率进行调节，当运行频率大于预设频率时，将压缩机的运行频率进行降低，然后控制四通阀执行换向动作。使得通过检测压缩机的运行频率判定是否需要先降低压缩机的运行频率再执行四通阀换向动作，削弱了四通阀换向时两端的压差，降低了四通阀换向时产生的噪音，同时降低了四通阀换向时降噪的成本。
进一步地，提出了本发明空调器控制方法第二实施例，该实施例中上述步骤S330包括：当所述压缩机的运行频率大于所述预设频率时，将所述压缩机的运行频率降低至所述预设频率；当所述压缩机的运行频率小于或等于所述预设频率时，控制所述压缩机维持当前的运行频率。
本实施例中，在检测得到压缩机的运行频率后，将压缩机的运行频率与预设频率进行作差比较，判断压缩机的运行频率与预设频率之间的大小关系。该预设频率可设置为30Hz～40Hz，也可根据具体情况而灵活设置。当压缩机的运行频率大于预设频率时，说明压缩机当前的运行频率比较高，四通阀两端的压差较大，此时将压缩机的运行频率降低至该预设频率，使得四通阀内部滑块两端的压差减小，滑块换向时冷媒冲击的声音减弱，达到降低噪音的目的。可以理解的是，当压缩机的运行频率大于预设频率时，也可将压缩机 的运行频率降低预设值，该预设值可根据具体情况而灵活设置。可选地，在对压缩机的运行频率进行降低后，可先延迟设定时间，等到压缩机按照调节后的运行频率进行运行稳定后，再执行四通阀的换向动作。该设定时间可设置为5秒钟，或者设置降低运行频率的幅度越大，设定时间越长，当然，也可根据实际情况进行设置。
当压缩机的运行频率小于或等于预设频率时，说明压缩机的运行频率较低，四通阀内部滑块两端的压差也较低，此时可以不需要对压缩机的运行频率进行调节，即压缩机维持当前的运行频率，滑块换向时冷媒冲击的声音较弱弱，产生的噪音较低。因此，此时对压缩机的运行频率进行调节的幅度为零，执行四通阀的换向动作。
本实施例当压缩机的运行频率大于预设频率时，降低至预设频率再执行四通阀的换向动作，使得保证压缩机的运行频率不大于预设频率的情况下执行四通阀换向动作，减小了四通阀内部滑块两端的压差，降低了四通阀换向时产生的噪音，提升了用户的满意度。当压缩机的运行频率小于或等于预设频率时，压缩机的运行频率调节的幅度为零，不仅能够降低四通阀换向时产生的噪音，而且提高了四通阀延迟执行换向动作的可靠性。
进一步地，提出了本发明空调器控制方法第三实施例，该实施例中上述步骤S340包括：控制所述四通阀内部滑块延迟预设时间后，执行换向动作。
本实施例中，当空调器的四通阀接收到换向指令，并对压缩机的运行频率进行调节后，控制四通阀内部滑块延迟预设时间后再执行换向动作。该预设时间可根据具体情况而灵活设置，可选地，可根据压缩机的运行频率与预设频率之间的大小关系，将预设时间设置为第一预设时间和第二预设时间，其中，第一预设时间大于第二预设时间。
具体地，在检测得到压缩机的运行频率后，若压缩机的运行频率大于预设频率，则将压缩机的运行频率降低至预设频率，该预设频率与上述的预设频率一致。同时，控制四通阀内部滑块延迟第一预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作。若压缩机的转速频率小于或等于预设频率，则压缩机维持当前的运行频率，同时，控制四通阀内部滑块延迟第二预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作。该第一预设时间和第二预设时间的具体取值可根据实际情况进行设 置，实现四通阀延迟换向动作的时间，进一步达到削弱换向阀滑块两端压差，降低换向噪音值的目的。
本实施例空调器的四通阀在执行换向动作时，控制四通阀延迟执行换向动作的时间，并当压缩机的转速频率小于或等于预设转速频率值时，缩短延迟时间。提高了四通阀延迟执行换向动作的可靠性，降低了四通阀换向时产生的噪音，提高用户使用空调的舒适度，同时降低了四通阀换向时降噪的成本。
对应地，如图4所示，提出本发明一种空调器控制装置第一实施例。该实施例的空调器控制装置包括：
侦测模块410，用于侦测空调器的四通阀是否接收到换向指令；
检测模块420，用于若所述空调器的四通阀接收到换向指令，则检测所述空调器的压缩机的运行频率；
本实施例中，该空调器可包括室内机和室外机，该室内机内可设有室内换热器组件及电子膨胀阀；室外机内可设有压缩机、四通阀、室外换热器、低压储液罐、电磁阀、毛细管、室外机节流部件以及室外机节流部件等等。其中，压缩机、四通阀、室内换热器组件、室外换热器、室外节流部件之间通过管路连接，形成制冷/制热循环回路。
本实施例中，空调器调用侦测模块410监听四通阀是否接收到换向指令，例如，空调器进行制热模式、制冷模式、除湿模式、送风模式等两两模式之间的切换，或者进行关机时，四通阀将会接收到换向指令。当空调器的四通阀接收到换向指令时，检测模块420检测空调器的压缩机的运行频率，以便根据压缩机的运行频率判定是否需要先降低压缩机的运行频率再执行四通阀换向动作。可选地，空调器也可以侦测四通阀是否接收到断电指令或通电指令，当四通阀接收到断电指令或通电指令时，说明四通阀接收到换向指令，即该换向指令包括断电指令和通电指令。当空调器的四通阀没有接收到换向指令时，空调器维持当前的运行状态。
调节模块430，用于根据所述压缩机的运行频率与预设频率之间的大小关系，对所述压缩机的运行频率进行调节；
本实施例中，在检测得到压缩机的运行频率后，调节模块430将压缩机的运行频率与预设频率进行比较，判断压缩机的运行频率大于预设频率。当 压缩机的运行频率大于预设频率时，调节模块430将压缩机的运行频率降低预设值，该预设值可根据压缩机的运行频率进行设置。在对压缩机的运行频率进行降低后，延迟预设时间，等待压缩机的运行频率稳定后，再执行四通阀的换向动作。该预设时间可设置为5秒钟，或者根据实际情况进行设置。当压缩机的运行频率小于或等于预设频率时，调节模块430对压缩机的运行频率进行调节的幅度为零，即压缩机维持当前的运行频率。该预设频率可设置为30Hz～40Hz，也可根据具体情况而灵活设置。
控制模块440，用于控制所述四通阀内部滑块执行换向动作，以削弱所述四通阀换向时两端的压差。
当上述对压缩机的运行频率进行调节后，保证压缩机的运行频率小于或等于预设频率，此时控制模块440可控制四通阀执行换向动作。具体地，四通阀内部滑块由当前移动方向往相反的方向移动，完成四通阀的换向动作。即四通阀在收到换向指令时，同时检测压缩机的运行频率，根据检测得到的运行频率进行调节后再执行四通阀换向动作。从而使得在不影响用户正常使用情况下，在压缩机运行时，当运行频率高于预设频率时将运行频率降低后，四通阀内部滑块两端的压差减小，滑块换向时冷媒冲击的声音减弱。
以下进行举例说明，假设空调器正常运行时，空调器的压缩机按照30Hz的运行频率正常运行时，室外机产生的噪音值为55.3分贝，空调器断电瞬间由于四通阀的换向，产生的噪音值有63分贝。而当压缩机按照70Hz的运行频率正常运行时，室外机产生的噪音值为57.3分贝，断电瞬间由于四通阀的换向，产生的噪音值有70.3分贝，该噪音非常大，影响用户使用空调器的舒适性。通过对比可知，当四通阀需执行换向动作时，将压缩机的运行频率降低，有助于降低室外机产生的噪音，提高用户使用空调的舒适度。因此，假设将预设频率设置为30Hz，空调器在运行的过程中，当四通阀接收到换向指令时，检测得到压缩机的运行频率为80Hz，大于预设频率，此时，可将压缩机的运行频率降低至30Hz，然后再控制四通阀内部滑块由当前移动方向往相反的方向移动，完成四通阀的换向动作，削弱了四通阀换向时两端的压差，降低了噪音。
本发明实施例空调器的四通阀在接收到换向指令后，根据压缩机的运行频率与预设频率之间的大小关系对压缩机的运行频率进行调节，当运行频率 大于预设频率时，将压缩机的运行频率进行降低，然后控制四通阀执行换向动作。使得通过检测压缩机的运行频率判定是否需要先降低压缩机的运行频率再执行四通阀换向动作，削弱了四通阀换向时两端的压差，降低了四通阀换向时产生的噪音，同时降低了四通阀换向时降噪的成本。
进一步地，提出了本发明空调器控制装置第二实施例，该实施例中上述调节模块430还用于，当所述压缩机的运行频率大于所述预设频率时，将所述压缩机的运行频率降低至所述预设频率；当所述压缩机的运行频率小于或等于所述预设频率时，控制所述压缩机维持当前的运行频率。
本实施例中，在检测得到压缩机的运行频率后，调节模块430将压缩机的运行频率与预设频率进行作差比较，判断压缩机的运行频率与预设频率之间的大小关系。该预设频率可设置为30Hz～40Hz，也可根据具体情况而灵活设置。当压缩机的运行频率大于预设频率时，说明压缩机当前的运行频率比较高，四通阀两端的压差较大，此时调节模块430将压缩机的运行频率降低至该预设频率，使得四通阀内部滑块两端的压差减小，滑块换向时冷媒冲击的声音减弱，达到降低噪音的目的。可以理解的是，当压缩机的运行频率大于预设频率时，也可将压缩机的运行频率降低预设值，该预设值可根据具体情况而灵活设置。可选地，在对压缩机的运行频率进行降低后，可先延迟设定时间，等到压缩机按照调节后的运行频率进行运行稳定后，再执行四通阀的换向动作。该设定时间可设置为5秒钟，或者设置降低运行频率的幅度越大，设定时间越长，当然，也可根据实际情况进行设置。
当压缩机的运行频率小于或等于预设频率时，说明压缩机的运行频率较低，四通阀内部滑块两端的压差也较低，此时调节模块430可以不需要对压缩机的运行频率进行调节，即压缩机维持当前的运行频率，滑块换向时冷媒冲击的声音较弱弱，产生的噪音较低。因此，此时对压缩机的运行频率进行调节的幅度为零，执行四通阀的换向动作。
本实施例当压缩机的运行频率大于预设频率时，降低至预设频率再执行四通阀的换向动作，使得保证压缩机的运行频率不大于预设频率的情况下执行四通阀换向动作，减小了四通阀内部滑块两端的压差，降低了四通阀换向时产生的噪音，提升了用户的满意度。当压缩机的运行频率小于或等于预设频率时，压缩机的运行频率调节的幅度为零，不仅能够降低四通阀换向时产 生的噪音，而且提高了四通阀延迟执行换向动作的可靠性。
进一步地，提出了本发明空调器控制装置第三实施例，该实施例中上述控制模块440还用于，控制所述四通阀内部滑块延迟预设时间后，执行换向动作。
本实施例中，当空调器的四通阀接收到换向指令，并对压缩机的运行频率进行调节后，控制模块440控制四通阀内部滑块延迟预设时间后再执行换向动作。该预设时间可根据具体情况而灵活设置，可选地，可根据压缩机的运行频率与预设频率之间的大小关系，将预设时间设置为第一预设时间和第二预设时间，其中，第一预设时间大于第二预设时间。
具体地，在检测得到压缩机的运行频率后，若压缩机的运行频率大于预设频率，则将压缩机的运行频率降低至预设频率，该预设频率与上述的预设频率一致。同时，控制模块440控制四通阀内部滑块延迟第一预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作。若压缩机的转速频率小于或等于预设频率，则压缩机维持当前的运行频率，同时，控制模块440控制四通阀内部滑块延迟第二预设时间后，由当前移动方向往相反的方向移动，完成四通阀的换向动作。该第一预设时间和第二预设时间的具体取值可根据实际情况进行设置，实现四通阀延迟换向动作的时间，进一步达到削弱换向阀滑块两端压差，降低换向噪音值的目的。
本实施例空调器的四通阀在执行换向动作时，控制四通阀延迟执行换向动作的时间，并当压缩机的转速频率小于或等于预设转速频率值时，缩短延迟时间。提高了四通阀延迟执行换向动作的可靠性，降低了四通阀换向时产生的噪音，提高用户使用空调的舒适度，同时降低了四通阀换向时降噪的成本。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
