结合图1所示，在一些实施例中，一种用于空调泄压的控制方法，空调包括：压缩机200，在压缩机200的排气管与回气管之间连通有泄压阀600；
方法包括：
S01，处理器获取空调的系统压力值；
S02，处理器确定系统压力值与泄压阀的关闭压力值之间的大小关系；
S03，处理器根据系统压力值与泄压阀的关闭压力值之间的大小关系控制泄压阀的开度。
采用本公开实施例提供的用于空调泄压的控制方法，在压缩机的排气管与回气管之间连通有泄压阀，能够通过泄压阀对制冷系统进行泄压，通过获取空调运行过程中的系统压力值，根据获取的系统压力值与关闭压力值之间的大小关系来控制泄压阀的开度，使制冷系统中高压侧的排气管中的压力泄压到低压侧的回气管中，从而更好地控制制冷系统中的系统压力，高效地对系统压力进行调节，使压缩机更稳定的运行，提高送风舒适性，进而提高用户的体验。
可以理解地，泄压阀的关闭压力值是指系统压力满足无需泄压的条件时，泄压阀此时的压力值，即泄压阀的关闭压力值为泄压阀是否需要打开的临界点，关闭压力值可以为空调出厂预设的，也可为根据空调的实际工况设定的，在此不作赘述。
结合图2和图3所示，在一些实施例中，空调包括制冷系统，制冷系统由压缩机200、冷凝器300、节流装置400和蒸发器500组成，压缩机200的排气管与冷凝器300的输入端连通，冷凝器300的输出端通过管路与蒸发器500的输入端连通，节流装置400连通于冷凝器300与蒸发器500的连通管路上，蒸发器500的输出端与压缩机200的回气管连通，泄压阀600连通于排气管与回气管之间。这样，通过制冷剂在制冷系统中循环达到制冷或制热的目的，由于制冷剂经压缩机200压缩后通过排气管排出高温高压状态的气体，高温高压状态的气体流经冷凝器300冷凝，然后经节流装置400节流降压，最终经蒸发器500蒸发为低温低压的气体通过回气管再次流入压缩机200内，因此在压缩机200的排气管与回气管之间形成压差，通过泄压阀600能够将排气管中的高压泄压到低压的回气管中，从而降低制冷系统的压力，保持压缩机200的稳定运行。
可选地，制冷系统上还设有压力检测模块，压力检测模块设置在制冷系统的高压侧，用于检测系统压力值，压力检测模块与处理器之间建立通信连接，处理器能够获取压力检测模块发送的系统压力值。这样，通过压力检测模块检测系统压力值，处理器能够获取压力检测模块发送的系统压力值，提高了系统压力值的获取精度，简化了获取过程。
结合图4所示，在一些可选地实施例中，一种用于空调泄压的控制方法，包括：
S011，处理器获取空调的系统高压侧压力值；
S021，处理器确定系统高压侧压力值与泄压阀的关闭压力值之间的大小关系；
S031，处理器根据系统高压侧压力值与泄压阀的关闭压力值之间的大小关系控制泄压阀的开度。
采用本公开实施例提供的用于空调泄压的控制方法，由于空调的制冷系统中节流装置的作用，使制冷系统中存在高压侧和低压侧，高压侧的压力过高会导致压缩机停机甚至损坏，因此需要对高压侧进行泄压，处理器获取空调的系统高压侧压力值，根据获取的高压 侧压力值与关闭压力值之间的大小关系来控制泄压阀的开度，能够更好地对空调的系统压力进行调节，提高压缩机运行的稳定性。
在一些具体的实施例中，处理器获取空调的系统高压侧压力值记为P con，预设的泄压阀的关闭压力值记为P s，处理器确定系统高压侧压力值与泄压阀的关闭压力值之间的大小关系是指处理器确定P con与P s之间的大小关系，根据P con与P s之间的大小关系来控制泄压阀的开度。
结合图5所示，在一些可选地实施例中，一种用于空调泄压的控制方法，包括：
S011，处理器获取空调的系统高压侧压力值；
S021，处理器确定系统高压侧压力值与泄压阀的关闭压力值之间的大小关系；
S032，在系统高压侧压力值小于或等于关闭压力值的情况下，处理器控制泄压阀关闭；
S033，在系统高压侧压力值大于关闭压力值的情况下，处理器控制泄压阀打开。
采用本公开实施例提供的用于空调泄压的控制方法，处理器通过获取空调的高压侧压力值，确定系统高压侧压力值与泄压阀的关闭压力值之间的大小关系来控制泄压阀的开度，在系统高压侧压力值小于或等于关闭压力值的情况下，此时空调的系统高压侧压力值相对较小，对压缩机的运行影响较小，因此处理器控制泄压阀关闭，无需对空调的制冷系统进行泄压，在系统高压侧压力值大于关闭压力值的情况下，此时空调的系统高压侧压力值相对较大，压缩机的运行受到压力影响，压缩机随时都面临停机或损坏的风险，因此处理器控制泄压阀打开，使制冷系统中高压侧的压力向低压侧泄压，快速降低制冷系统的压力，使压缩机稳定运行，提高制冷制热的稳定性。
可选地，系统高压侧压力值小于或等于关闭压力值是指：系统高压侧压力值P con小于或等于关闭压力值P s。
可选地，系统高压侧压力值大于关闭压力值是指：系统高压侧压力值P con大于关闭压力值P s。
可选地，在系统高压侧压力值大于关闭压力值的情况下，处理器控制泄压阀打开，包括：在空调为定频空调的情况下，处理器控制泄压阀打开进行泄压，直至开度至最大。这样，在系统高压侧压力值大于关闭压力值的情况下，系统内的压力过高，需要降低系统压力维持空调的稳定运行，但是在空调为定频空调的情况下，压缩机的频率无法调节进行降频，因此处理器控制泄压阀打开进行泄压，使系统内的高压侧压力向低压侧泄压，控制泄压阀的开度直至最大，能够高效地降低系统压力，提高空调的运行稳定性，对压缩机进行 保护。
可选地，在空调为定频空调的情况下，处理器控制泄压阀打开进行泄压，直至开度至最大后，包括：获取空调的系统高压侧压力值，在系统高压侧压力值小于或等于关闭压力值的情况下开始计时，在系统高压侧压力值小于或等于关闭压力值持续t3时长后，控制泄压阀关闭。这样，对于定频空调，压缩机的频率无法改变，在获取的系统高压侧压力值大于关闭压力值的情况下，无法通过降低压缩机频率来降低系统压力，因此处理器需要控制泄压阀打开进行泄压，快速降低系统压力，在泄压阀的开度直至最大后，泄压阀的泄压能力达到最强，因此处理器再次获取空调的系统高压侧压力值，在系统高压侧压力值小于或等于关闭压力值时开始计时，并在持续t3时长后控制泄压阀关闭，在系统高压侧压力值小于或等于关闭压力值持续t3时长后，此时系统压力的降压效果较好，若继续保持泄压阀打开的状态，会导致系统压力不足，影响制冷或制热效果，因此控制泄压阀关闭，使空调趋于稳定运行的同时，保障其制冷制热效果。
在一个具体的实施例中，t3时长可为20秒。在泄压阀打开至最大开度对制冷系统进行泄压后，若系统高压侧压力值小于或等于关闭压力值持续20秒后，此时系统压力的降压效果较好，为保障空调的制冷制热效果，处理器需要控制泄压阀关闭。
可选地，在系统高压侧压力值大于关闭压力值的情况下，处理器控制泄压阀打开，包括：在空调为变频空调的情况下，处理器获取系统高压侧压力值大于关闭压力值的时长，在时长大于t1的情况下，处理器控制泄压阀打开。这样，在系统高压侧压力值大于关闭压力值的情况下，系统内的压力过高，需要降低系统压力维持空调的稳定运行，但是在空调为变频空调的情况下，压缩机具有自调节能力，因此处理器获取系统高压侧压力值大于关闭压力值的时长，在时长大于t1的情况下，处理器才控制泄压阀打开，因为在处理器获取系统高压侧压力值大于关闭压力值持续t1时长后，即说明此时压缩机的自调节已无法有效降低系统压力，因此处理器控制泄压阀打开通过泄压阀将系统高压侧的压力向低压侧泄压，高效地降低系统压力，提高压缩机运行的稳定性，对压缩机进行保护。
可选地，在时长大于t1的情况下，处理器控制泄压阀打开，包括：在泄压阀打开t2时长后，处理器控制压缩机降频。这样，在处理器获取系统高压侧压力值大于关闭压力值持续t1时长后，即说明此时压缩机的自调节已无法有效降低系统压力，因此处理器控制泄压阀打开通过泄压阀将系统高压侧的压力向低压侧泄压，在泄压阀打开t2时长后，处理器控制压缩机降频对泄压阀进行辅助降压，通过泄压阀打开和压缩机降频两种控制手段，进一步提高空调的系统压力的降压效率，而且通过降低压缩机频率，使压缩机的负荷降低，进一步提高了压缩机运行的稳定性，对压缩机进行保护。
可选地，在泄压阀打开t2时长后，处理器控制压缩机降频，包括：在泄压阀打开t2时长后，处理器控制泄压阀以当前开度进行泄压，同时控制压缩机降频。这样，在处理器控制泄压阀打开t2时长后，此时系统压力已经下降，为保持系统内的压力以及空调的制冷制热效果，处理器控制泄压阀以当前开度进行泄压，无需再增大泄压阀的开度，同时控制压缩机降频，减少排气量降低排气温度，从而更好地降低系统压力，在保障空调的制冷制热效果的同时，高效地降低空调的系统压力。
可选地，在泄压阀打开t2时长后，处理器控制压缩机降频，包括：处理器控制压缩机以预设降幅降频，同时获取系统高压侧压力值，在系统高压侧压力值小于或等于关闭压力值的情况下，处理器控制泄压阀关闭，压缩机停止降频。这样，在处理器控制泄压阀打开t2时长后，处理器控制压缩机以预设降幅降频，能够提高压缩机在进行降频调节时的稳定性，同时处理器再次获取系统高压侧压力值，在系统高压侧压力值小于或等于关闭压力值的情况下，此时系统压力的降压效果较好，处理器控制泄压阀关闭，压缩机停止降频，从而降低系统降压对空调制冷制热造成的影响，在保障空调的制冷制热效果的同时，更好地调节空调的系统压力。
可选地，处理器控制压缩机以预设降幅降频，包括：处理器控制压缩机以每5秒降低1Hz的预设降幅进行降频。这样，使压缩机以较低的降幅进行降频，提高了压缩机降频时的稳定性，避免压缩机大幅降频造成空调的制冷制热效果急剧下降，提高了空调的送风舒适性。
在一些具体的实施例中，时长t1可为5秒，时长t2可为10秒；在空调为变频空调的情况下，处理器在确定获取的系统高压侧压力值大于关闭压力值，且持续时长大于5秒时，处理器控制泄压阀打开；在处理器控制泄压阀打开10秒后，控制泄压阀以当前开度泄压，并控制压缩机降频。这样，在空调为变频空调的情况下，当空调的系统高压侧压力值大于关闭压力值，压缩机能够进行自调节，在空调的系统高压侧压力值大于关闭压力值的时长持续5秒后，说明压缩机的自调节已不能满足系统降压的需求，因此控制泄压阀打开将制冷系统中高压侧的压力泄压到低压侧，在控制泄压阀打开10秒后，此时系统压力已有所下降，因此控制压缩机进行降频辅助降压，并控制泄压阀以当前开度泄压，同时控制压缩机降频，避免泄压阀开度过大导致系统中压力较低，从而影响空调的制冷制热效果，在降低泄压对空调的制冷制热影响的同时，更好地对系统压力进行调节，保护压缩机的运行，提高压缩机运行的稳定性。
在一些具体的实施例中，处理器控制泄压阀打开，包括：处理器控制泄压阀打开，并根据如下公式调节泄压阀的开度：
b＝[(P con-P s)/(P o-P s)]*B
其中，b为泄压阀的开度，B为泄压阀的最大开度，P con为系统高压侧压力值，P s为泄压阀的关闭压力值，P o为泄压阀的全开压力值，且P o>P s。这样，处理器控制泄压阀打开，并根据获取的系统高压侧压力值和泄压阀的关闭压力值之间的差值与泄压阀的全开压力值和泄压阀的关闭压力值之间的差值的比值与泄压阀的最大开度之间的乘积来确定泄压阀的开度，从而使泄压阀的开度与系统高压侧压力值、泄压阀的关闭压力值、泄压阀的全开压力值以及泄压阀的最大开度之间相关联，更精准地调节泄压阀的开度，使泄压阀既能较好地对系统压力进行泄压，又能降低泄压对空调制冷制热的影响，进一步提高压缩机运行的稳定性，提高空调的送风舒适性。
可以理解地，泄压阀的全开压力值P o可为空调出厂预设的，也可为根据空调的实际工况以及空调运行时的系统高压侧压力达到最大临界值时获得的，在此不作赘述，上述公式可为预先写入处理器执行程序中的，处理器在获取系统高压侧压力值P con时，将P con代入上述公式中求得泄压阀的开度b。
