Description

用于空调器的控制方法 技术领域
本发明属于空调器技术领域，具体提供一种用于空调器的控制方法。
背景技术
随着社会的发展，空调器越来越普及，空调器节能的问题愈发显得重要，在常规空调产品的制冷运转中，房间内温度达到设定值精度范围内后，压缩机会停止运行，由于温度传感器放置在室内机的回风侧，为了保证检测房间温度的准确性，在压缩机停机后，需要室内机的风机持续运行，从而保证室内空气流经环温传感器，环温升高至设定值回差温度范围之外时，压缩机再次启动制冷运行。
现有技术中，在室内环境温度上升的期间，即空调器的压缩机停止运行到重新开始运行期间，风机始终处于运转状态，这样设置的不利之处在于：第一，由于风机一直保持送风运转，风机处于带电运转状态，消耗电能，浪费能源，增加用户的使用费用；第二，由于风机带电持续运行，电机会发热，大部分电能转化为热能的形式，散发到房间内，相当于为房间增加了热负荷；第三，风机持续送风运转会产生噪音，影响用户的舒适性。也就是说，采用现有技术的风机控制方式会浪费能源，不利于空调器的节能，且风机持续运行也相当于一个热源，增加房间负荷，并且风机产生噪音，导致用户体验不佳。
因此，本领域需要一种新的用于空调器的控制方法来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有空调器的风机控制方式不利于节能，增加室内热负荷并且产生噪音，导致用户体验不佳的问题，本发明提供了一种用于空调器的控制方法，空调器包括室内机和压缩机，控制方法包括：在第一预设温度和第二预设温度所形 成的温度区间内使室内机的风机运行并持续第一预设时间；获取第一预设时间结束时的室内环境温度；根据第一预设时间结束时的室内环境温度，选择性地对风机进行调节，其中，第一预设温度为空调器制冷时使压缩机停止运行时的室内环境温度，第二预设温度为空调器制冷时使压缩机开始运行时的室内环境温度。
在上述控制方法的优选技术方案中，“根据第一预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤具体包括：如果第一预设时间结束时的室内环境温度小于或等于第一预设值，则使风机停止运行并持续第二预设时间。
在上述控制方法的优选技术方案中，“根据第一预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤还包括：如果第一预设时间结束时的室内环境温度大于第一预设值，则使风机保持运行。
在上述控制方法的优选技术方案中，在“使风机停止运行并持续第二预设时间”的步骤之后，控制方法还包括：使风机运行并持续第三预设时间；获取第三预设时间开始时的室内环境温度和第三预设时间结束时的室内环境温度；计算第三预设时间结束时的室内环境温度与第三预设时间开始时的室内环境温度的差值；根据差值和第三预设时间结束时的室内环境温度，选择性地对风机进行调节。
在上述控制方法的优选技术方案中，“根据差值和第三预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤具体包括：如果差值小于或者等于第二预设值且第三预设时间结束时的室内环境温度小于或等于第三预设值，则使风机停止运行并持续第四预设时间，其中，第四预设时间大于第二预设时间。
在上述控制方法的优选技术方案中，“根据差值和第三预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤还包括：如果差值大于第二预设值且第三预设时间结束时的室内环境温度小于或等于第三预设值，则使风机停止运行并持续第五预设时间，其中，第五预设时间等于第二预设时间。
在上述控制方法的优选技术方案中，“根据差值和第三预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤还包括： 如果第三预设时间结束时的室内环境温度大于第三预设值，则使风机保持运行。
在上述控制方法的优选技术方案中，第三预设值等于第一预设值。
在上述控制方法的优选技术方案中，第一预设值等于第二预设温度与第一预设温度的差值的80％再加上第一预设温度。
在上述控制方法的优选技术方案中，第二预设值等于第二预设温度与第一预设温度的差值的20％。
本领域技术人员能够理解的是，在本发明的优选技术方案中，空调器制冷时由于室内环境温度达到第一预设温度，此时压缩机停止运行，然后使风机运行第一预设时间，并获取第一预设时间结束时的室内环境温度，通过这个室内环境温度，可以判断当前室内的温度情况，并决定室内机的风机是否需要调节，通过这样的设置，可以灵活地对风机进行控制，即在不需要风机运行时可以使风机停止运行，避免产生过多的能耗，使空调器更加节能，并且由于风机可以停转，使得风机不会产生热量，避免增加室内的热负荷，且不会产生噪音，进而提升用户体验。
进一步地，在第一预设时间结束时的室内环境温度小于或等于第一预设值的情况下，说明此时室内环境温度没有出现极大温升，此时可以使室内机的风机停止运行，避免造成能源的浪费，使空调器节能，同时风机不会产生热量也不会将热量带进室内，并且不会形成噪音，提升用户体验。
进一步地，在第一预设时间结束时的室内环境温度大于第一预设值的情况下，说明此时室内环境温度出现极大温升，即室内环境温度上升速度很快，此时需要室内机的风机保持运行，避免引起室内环境温度异常波动以影响用户的舒适性。
进一步地，在风机停止运行并持续第二预设时间后，再使风机开始运行并持续第三预设时间，通过第三预设时间结束时的室内环境温度与第三预设时间开始时的室内环境温度的差值以及第三预设时间结束时的室内环境温度，选择性地对风机进行调节，即在风机停止运行后每次再次运行时，仍旧可以灵活地对风机进行控制，即在不需要风机运 行时可以使风机停止运行，避免产生过多的能耗，使空调器更加节能，并且由于风机可以停转，使得风机不会产生热量，避免增加室内的热负荷，且不会产生噪音，进而提升用户体验。
进一步地，在上述差值小于或者等于第二预设值且第三预设时间结束时的室内环境温度小于或等于第三预设值，说明此时室内热负荷很小，室内环境温度回升很慢，这时候可以适当延长风机停转的时间。
进一步地，在上述差值大于第二预设值且第三预设时间结束时的室内环境温度小于或等于第三预设值，说明此时室内热负荷中等，室内环境温度回升的趋势较大，这时候不合适延长风机停转的时间，应该与之前的停转时间保持一致。
进一步地，在第三预设时间结束时的室内环境温度大于第三预设值的情况下，说明此时室内环境温度出现极大温升，即室内环境温度上升速度很快，此时需要室内机的风机保持运行，避免引起室内环境温度异常波动以影响用户的舒适性。

基于背景技术指出的现有空调器的风机控制方式不利于节能，增加室内热负荷并且产生噪音，导致用户体验不佳的问题，本发明提供了一种用于空调器的控制方法，旨在避免产生过多的能耗，使空调器更加节能，并且由于风机可以停转，使得风机不会产生热量，避免增加室内的热负荷，且不会产生噪音，进而提升用户体验。
具体地，本发明的空调器包括室内机、室外机、压缩机、电子膨胀阀和四通阀，室内机、室外机、压缩机和电磁膨胀阀构成闭环的冷媒循环系统，四通阀配置成能够切换冷媒循环系统中冷媒的流动方向，从而使空调器能够在制冷和制热之间进行切换。如图1所示，本发明的控制方法包括：在第一预设温度和第二预设温度所形成的温度区间内使室内机的风机运行并持续第一预设时间；获取第一预设时间结束时的室内环境温度；根据第一预设时间结束时的室内环境温度，选择性地对风机进行调节，其中，第一预设温度为空调器制冷时使压缩机停止运行时的室内环境温度，第二预设温度为空调器制冷时使压缩机开始运行时的室内环境温度。也就是说，在空调器制冷时，室内环境温度会逐渐降低，此时压缩机始终运行，在室内环境温度达到第一预设温度时，压缩机停止运行，接下来室内环境温度开始回升，在室内环境温度回升到第二预设温度时，压缩机需要重新开启，使空调器继续进行制冷，通过这种方式，使室内温度保持在一定的温度范围内，从而满足用户的使用需求，本发明通过在室内环境温度回升的期间加入对风机的判断，使得可以在不需要使用风机时可以将风机停转一段时间，从而使空调器更加节能，如果需要使用风机，那么风机会持续运转或者重新开始运转，使得不会使室内环境温度产生极大的波动。其中，获取室内环境温度可以通过设置在空调器上的温度传感器来进行检测获取，亦或者通过其他家用设备获取，然后再将室内环境温度数据传输给空调器，又或者通过人工输入的方式将室内环境温度输入到空调器中，本领域技术人员可以在实际应用中灵活地设置室内环境温度的获取方式和途径，这种获取室内环境温度的方式和途径的选择、调整和改变均不构成对本发明的限制。此外，在一般情况下，第一预设温度是用户设定的温度，第二预设温度是系统提前设定的温度，即当用户感觉室内较热时，开启空调器制冷，当达到用户设定的第一预设温度时，说明此时室内环境温度达到用户的使用要求，空调器的压缩机停止运行，暂定制冷，当温度逐渐回升到第二预设温度时，空调器需要重新开启压缩机，使空调器重新开始制冷。
需要说明的是，上述中在温升区间内使风机运行并持续第一预设时间可以是压缩机刚刚停止时使风机持续运行第一预设时间，也可以是压缩机停止一段时间后再使风机持续运行第一预设时间(即在压缩 机停止运行之后风机也有过至少一次停转)，本领域技术人员可以在实际应用中灵活地设置第一预设时间在温升区间内选取位置，只要能够通过第一预设时间结束时的室内环境温度，选择性地对风机进行调节即可。
优选地，“根据第一预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤具体包括：如果第一预设时间结束时的室内环境温度小于或等于第一预设值，则使风机停止运行并持续第二预设时间。也就是说，在这种情况下，室内环境温度上升不大，可以使风机停止运行一段时间。
优选地，“根据第一预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤还包括：如果第一预设时间结束时的室内环境温度大于第一预设值，则使风机保持运行。也就是说，在这种情况下，室内环境温度已经很高了，风机应该继续运行，避免室内环境温度出现异常波动。
需要说明的是，本领域技术人员可以在实际应用中灵活地设置第一预设时间和第二预设时间的具体时间大小，只要能够通过风机运行第一预设时间结束时的室内环境温度来判断风机是否需要停止运行即可，以及通过风机停止运行第二预设时间来实现节能即可。
在本发明中，如果前述中第一预设时间的开始时间为压缩机刚刚停止运行的时间，即在压缩机停止运转并且风机运行了第一预设时间后就开始进行风机的首次判断，还可以在后续的风机判断中通过引入另一参数来判断风机是否需要延长停机时间，具体而言，在“使风机停止运行并持续第二预设时间”的步骤之后，本发明控制方法还包括：使风机运行并持续第三预设时间；获取第三预设时间开始时的室内环境温度和第三预设时间结束时的室内环境温度；计算第三预设时间结束时的室内环境温度与第三预设时间开始时的室内环境温度的差值；根据差值和第三预设时间结束时的室内环境温度，选择性地对风机进行调节。也就是说，通过上述第三预设时间结束时的室内环境温度与第三预设时间开始时的室内环境温度的差值以及第三预设时间结束时的室内环境温度，来组合判断是否需要对风机进行调节。其中，第三预设时间可以设置为等于第一预设时间，即在每次风机判断时都使风机先运行同样的时间，当然，第三预设时间还可以设置为不等于第一预设时间，本领域技 术人员可以在实际应用中灵活地第三预设时间的具体时间大小，只要能够通过风机运行第三预设时间结束时的室内环境温度以及第三预设时间结束时的室内环境温度与第三预设时间开始时的室内环境温度的差值的组合判断风机是否需要延长停转时间即可。
优选地，“根据差值和第三预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤具体包括：如果差值小于或者等于第二预设值且第三预设时间结束时的室内环境温度小于或等于第三预设值，则使风机停止运行并持续第四预设时间，其中，第四预设时间大于第二预设时间。也就是说，在这种情况下，室内的热负荷小，室内环境温度回升很慢，应该适当延长风机停转时间。
优选地，“根据差值和第三预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤还包括：如果差值大于第二预设值且第三预设时间结束时的室内环境温度小于或等于第三预设值，则使风机停止运行并持续第五预设时间，其中，第五预设时间等于第二预设时间。也就是说，在这种情况下，室内的热负荷中等，室内环境温度有比较大的回升趋势，应该保持之前的风机停转时间。
优选地，“根据差值和第三预设时间结束时的室内环境温度，选择性地对风机进行调节”的步骤还包括：如果第三预设时间结束时的室内环境温度大于第三预设值，则使风机保持运行。也就是说，在这种情况下，室内环境温度已经很高了，风机应该继续运行，避免室内环境温度出现异常波动。
需要说明的是，第三预设值可以设置为等于第一预设值，即每次进行风机判断时，都通过将每次风机运行一段时间结束时的室内环境温度与同一个预设值比较，然后进行风机判断。当然，第三预设值还可以设置为不等于第一预设值，本领域技术人员可以在实际应用中灵活地设置第三预设值的具体温度值。
如图2所示，下面结合一个最为优选的实施例来详细地阐述本发明的技术方案。
首先，室内环境温度为Tr，第一预设温度为Ts，第二预设温度为Ts+T0，第一预设温度和第二预设温度形成了温差为T0的室内环境温度回升区间，本实施例在Ts至(Ts+T0)温度的回升区间内对室内 机的风机进行智能控制。其中，第一预设值和第三预设值均为Ts+0.8×T0，第二预设值为0.2×T0。
首先，当Tr≤Ts，即室内环境温度达到第一预设温度后，压缩机停止运行，室内风机继续送风运行t0秒，检测t0时间段起始时刻室温Tr1，终止时刻室温Tr2，则t0时间段内温升为ΔT＝(Tr2-Tr1)，若Tr2≤(Ts+0.8×T0)，则室内风机停止运转t1秒，进入休眠停止状态，整个机组处于休眠状态。
然后，如果在t1秒过去后，风机再次启动运行t0秒，若检测ΔT≤0.2*T0且Tr2≤(Ts+0.8×T0)，则在停机t1时长的基础上增加延长停机时间常数Δt，即第二次休眠停机时长为(t1+Δt)；然后风机再次启动运行t0秒，若满足上述条件，则在上次停机时长的基础上再增加Δt时长，延长停机时长，直至最长停机时间(t1+3×Δt)；在上述中，如果t1秒过去后，风机再次启动运行t0秒，若检测ΔT＞0.2*T0，但满足Tr2≤(Ts+0.8×T0)，则风机停止时间固定为t1时长，不在上次停机时长的基础上追加Δt停机时长。
在上述中，如果检测到Tr2＞(Ts+0.8×T0)，则风机保持送风运转，不再进行停止。
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。
