具体实施方式
为了使本公开所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处所描述的具体实施 例仅仅用以解释本公开，并不用于限定本公开。
由此，本说明书中所指出的一个特征将用于说明本公开的一个实施方式的其中一个特征，而不是暗示本公开的每个实施方式必须具有所说明的特征。此外，应当注意的是本说明书描述了许多特征。尽管某些特征可以组合在一起以示出可能的系统设计，但是这些特征也可用于其他的未明确说明的组合。由此，除非另有说明，所说明的组合并非旨在限制。
下面结合附图以及实施例对本公开的原理及结构进行详细说明。
本公开的发明人发现上述相关技术中存在如下问题：如果使用电加热系统进行加热，则会使恒温恒湿机的耗电增加，能效降低。
鉴于此，本公开提供了一种热泵系统及其控制方法、装置以及空调设备、存储介质，使用热泵系统实现除湿再热、制热升温等功能，可以实现热回收除湿再热并且使出风温度可调，不需使用电加热系统，能够降低能耗，提升节能性能；使用双室外侧换热器，可以实现异步化霜且化霜时进入室内侧换热器的冷媒保持高压状态，能够保持室内侧热量输出，减小化霜时因室内侧换热器不制热导致的室内温度大幅波动，提高用户的使用感受度。
在一些实施例中，如图1所示，本公开提供一种热泵系统，包括室内机100、室外机200和阀门组件001。室内机包括压缩机01、第一控制阀06、第一室内换热器08和第二室内换热器09。
阀门组件001分别与压缩机01的排气口和吸气口、第二室内换热器09的第一端、室外机200的第一端连接，第二室内换热器09的第二端与室外机200的第二端连接。阀门组件001可以有多种实现方式，阀门组件001用于控制冷媒的流向和通断，形成冷媒回路，通过控制阀门组件001的动作能够实现制冷、制热等功能。
第一室内换热器08的第一端与压缩机01的排气口连接，第二端通过第一连接管路002与第二室内换热器09的第二端和室外机200的第二端之间的第二连接管路003相连通，接入冷媒回路。第一控制阀06设置在第一室内换热器08的第一端与压缩机01的排气口之间的管路中。

热泵系统在除湿功能下通常送出的风比较凉，需要再热送风，现在有技术中一般采用电加热的方式对出风进行加热。通过控制第一控制阀06的导通或截止，压缩机01的排气口输出的冷媒可以进入第一室内换热器08，第一室内换热器08输出的冷媒通过第一连接管路002进入热泵系统的冷媒回路，在保留热泵系统的基本功能的同时，当室内湿度大于设定湿度，且室内温度小于等于设定湿度时，为避免温度超调，利用第一室内换热器08产生的冷凝热进行再热送风。通过利用第一室内换热器08产生的冷凝热对空气进行再热，实现除湿时的空气再热功能，使用第一室内换热器08产生的冷凝热来实现除湿再热功能，相比于电加热系统更加经济和节能。

在一些实施例中，当运行模式为除湿再热、第一制热模式时，通过控制第一控制阀06的动作(导通)，以使室内机的第一室内换热器08用于对空气再热。在运行模式为制冷/除湿模式、化霜模式、第二制热模式的情况下，通过控制第一控制阀06的动作(关闭)，以使第一室内换热器08停止工作。
在除湿再热模式下，可以利用第一室内换热器08的冷凝热进行再热送风，或者在第一制热模式下，也可以利用第一室内换热器08的冷凝热进行加热。在制冷/除湿模式、化霜模式、第二制热模式等模式下，压缩机01输出的冷媒不进入第一室内换热器08，第一室内换热器08停止工作，不产生冷凝热。

压缩机01的排气口排出的第三路冷媒通过第二四通阀03、截止阀14、第一室外换热器20、第三节流装置22、储液罐26、截止阀15、第二节流装置13、第二室内换热器09、第一四通阀02和第二四通阀03，返回至压缩机01的吸气口。
在一些实施例中，当运行模式为第二除湿再热模式时，控制第一四通阀02的第一端口D1与第二端口E1连通、第三端口C1与第四端口S1连通；控制第二四通阀03的第一端口D2与第三端口C2连通、第二端口E2与第四端口S2连通；控制第一控制阀06、第三控制阀05为导通状态，并且控制第二控制阀04为截止状态。
如图7所示，在第二除湿再热模式下，压缩机01的排气口排出的第一路冷媒通过第一室内换热器08后，通过第一节流装置12、第二节流阀13进入第二室内换热器09。第一室内换热器08产生冷凝热。
压缩机01的排气口排出的第二路冷媒通过第二四通阀03、截止阀14、第一室外换热器20、第三节流装置22、储液罐26；通过第三节流装置22输出的部分冷媒可以通过第四节流装置23、第二室外换热器21、截止阀14、第一四通阀02，返回压缩机01的吸气口。
在一些实施例中，如图8所示，当运行模式为第三除湿再热模式时，控制第一四通阀02的第一端口D1与第三端口C1连通、第二端口E1与第四端口S1连通；控制第二四通阀03的第一端口D2与第二端口E2连通、第三端口C2与第四端口S2连通；控制第一控制阀06、第二控制阀04为导通状态，并且控制第三控制阀05为截止状态。
如图8所示，在第三除湿再热模式下，压缩机01的排气口排出的第一路冷媒通过第一室内换热器08后，通过第一节流装置12、第二节流阀13进入第二室内换热器09。第一室内换热器08产生冷凝热。

在一些实施例中，除湿再热是通过第一室内换热器08和第二室内换热器09相互配合实现的，第二室内换热器09负责除湿和降温，由于室内湿负荷和冷负荷不相等， 热泵系统输出以湿负荷和冷负荷的大者为调节依据，当湿负荷大于冷负荷，会导致室内温度超调(当前室内环境温度低于设定温度)，这时第一室内换热器08介入调节冷负荷，即补偿输出过大的制冷量，使得室内温度和设定值匹配。
在制热过程中，湿负荷一般是加湿负荷，恒温恒湿机有专用加湿器，不涉及室内换热器动作；冬季热负荷主要由第一室内换热器08和第二室内换热器09相互配合实现的，共有三种状态，根据热负荷需求不同，可以是第一室内换热器08工作、第二室内换热器09工作、第一室内换热器08和第二室内换热器09共同工作。
在一些实施例中，当运行模式为第一制热模式时，控制第一四通阀02的第一端口D1与第二端口E1连通、第三端口C1与第四端口S1连通；控制第二四通阀03的第一端口D2与第二端口E2连通、第三端口C2与第四端口S2连通；控制第一控制阀06、第二控制阀04和第三控制阀05为导通状态。
如图9所示，在第一制热模式下，压缩机01的排气口排出的第一路冷媒通过第一室内换热器08后，通过第一节流装置12、截止阀15进入储液罐26。第一室内换热器08产生冷凝热。

储液罐26输出的一路冷媒经过第四节流装置23、第二室外换热器21、截止阀14、第一四通阀02，返回压缩机01的吸气口；储液罐26输出的另一路冷媒经过第三节流装置22、第一室外换热器20、截止阀14、第二四通阀03，返回压缩机01的吸气口。

如图10所示，在第二制热模式下，压缩机01的排气口排出的冷媒不通过第一室内换热器08，第一室内换热器08不进行工作。压缩机01的排气口排出的第二路冷媒通过第一四通阀02、第二室内换热器09、第二节流装置13、截止阀15，进入储液罐26。压缩机01的排气口排出的第三路冷媒通过第二四通阀03、第二室内换热器09、第二节流装置13、截止阀15，进入储液罐26。
储液罐26输出的一路冷媒经过第四节流装置23、第二室外换热器21、截止阀14、第一四通阀02，返回压缩机01的吸气口；储液罐26输出的另一路冷媒经过第三节流装置22、第一室外换热器20、截止阀14、第二四通阀03，返回压缩机01的吸气口。
在一些实施例中，当运行模式为第一化霜模式时，控制第一四通阀02的第一端口D1与第三端口C1连通、第二端口E1与第四端口S1连通；控制第二四通阀03的第一端口D2与第二端口E2连通、第三端口C2与第四端口S2连通；控制第一控制阀06和第二控制阀04为截止状态，并且控制第三控制阀05为导通状态。
如图11所示，在第一化霜模式下，压缩机01的排气口排出的冷媒不通过第一室内换热器08，第一室内换热器08不进行工作。
压缩机01的排气口排出的第一路冷媒通过第一四通阀02、截止阀14、第二室外换热器21、第四节流装置23后，通过经过第三节流装置22、第一室外换热器20、截止阀14、第二四通阀03，返回压缩机01的吸气口，进行化霜处理。压缩机01的排气口排出的第二路冷媒通过第二四通阀03、第二室内换热器09、第二节流装置13、截止阀15进入储液罐26，储液罐26输出的冷媒经过第三节流装置22、第一室外换热器20、截止阀14、第二四通阀03，返回压缩机01的吸气口。
在一些实施例中，当运行模式为第二化霜模式时，控制第一四通阀02的第一端口D1与第二端口E1连通、第三端口C1与第四端口S1连通；控制第二四通阀03的第一端口D2与第三端口C2连通、第二端口E2与第四端口S2连通；控制第一控制阀06和第三控制阀05为截止状态，并且控制第二控制阀04为导通状态。
如图12所示，在第二化霜模式下，压缩机01的排气口排出的冷媒不通过第一室内换热器08，第一室内换热器08不进行工作。压缩机01的排气口排出的第一路冷媒通过第二四通阀03、截止阀14、第一室外换热器20、第三节流装置22后，通过经过第四节流装置23、第二室外换热器21、截止阀14、第一四通阀04，返回压缩机01的吸气口，进行化霜处理。
压缩机01的排气口排出的第二路冷媒通过第一四通阀02、第二室内换热器09、第二节流装置13、截止阀15进入储液罐26。储液罐26输出的冷媒经过第四节流装置23、第二室外换热器21、截止阀14、第一四通阀04，返回压缩机01的吸气口。
在一些实施例中，当室内有冷负荷或湿负荷时，系统先进入制冷/除湿模式，可以使用室内环境温度与设定温度的差值的函数关系式表征冷负荷，可以使用室内含湿量与设定含湿量的差值的函数关系式表征湿负荷。当湿负荷大于冷负荷时，例如，含 湿量未到设定值，但室内温度已经比设定低，则会进入第一除湿再热模式。
当在第一除湿再热模式下，如果湿负荷已达到预设值，但热负荷不满足(当前室内温度比预设温度低)，则第一节流装置12的步数开大，增大第一室内换热器08的换热量；如果第一室内换热器08的换热量最大(第一室外换热器20、第二室外换热器21换热量降至最低)，仍不满足室内热负荷要求(当前室内温度比预设温度低)，则进入第二除湿再热模式或第三除湿再热模式；压缩机01提高能力输出，进一步增大第一室内换热器08的换热量，切换至低压侧的第一室外换热器20或第二室外换热器21，分流压缩机01多输出的低压侧流量，从而保持第二室内换热器09的换热量保持不变，保持控湿的稳定。
当室内有热负荷需求时，则进入第一制热模式或第二制热模式，第一化霜模式或第二化霜模式根据对应室外侧换热器是否需要化霜对应的条件而触发。
当室内温度小于设定温度，需要升温，但热泵系统会存在室外换热器结霜化霜的问题，会导致温度波动不满足要求，此时需要进行化霜。热泵系统使用双室外侧换热器，采用第一化霜模式和第二化霜模式可以做到异步化霜，且化霜时室内侧换热器依然保持高压状态，保持室内侧热量输出，减小普通热泵空调化霜时因室内侧换热器不制热导致的室内温度大幅波动。
在一些实施例中，热泵系统的运行模式与部件控制状态对应的第一控制表如下表1所示：
