具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅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做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义，“多种”一般包含至少两种。

下面结合附图详细说明本申请的可选实施例。
图1是根据本申请一实施例的热泵系统的结构示意图，如图1所示。热泵系统，即空气源热泵采暖系统。在本申请的一实施例中，热泵系统的制热主机采用变频空气源 热泵机组，水泵采用变频水泵，采暖末端采用风机盘管。热泵系统包括：相连接的分水器、多个热泵机组、集水器；多个热泵机组(例如变频空气源热泵机组)与集水器之间的管路上设置有多个变频水泵；热泵系统还包括：第一温度传感器，设置在分水器的供水管上；第二温度传感器，设置在集水器的回水管上。控制器，用于根据变频水泵的运行频率，以及第一温度传感器和第二温度传感器采集的温度数据，调整热泵机组的出水温度。分水器的供水管和集水器的回水管上还设置有压力传感器，以监测管路压力，保证管路内压力值处于正常工作范围。
当室内建筑热负荷随室外温度的上升而下降时，风机盘管的换热能力即大于室内的负荷需求，针对变频系统可以通过优先调节水流量的方式实现空气源热泵采暖系统的供热量按需供应，因此在分水器的供水管上还设置有流量传感器，用于监测管路水流量。当水流量调节至极限后再执行出水温度的调节方案，即根据变频水泵的运行频率，以及第一温度传感器和第二温度传感器采集的温度数据，调整热泵机组的出水温度，以满足室内的负荷需求，从而保证供需关系，实现系统节能。
建筑热负荷受室外工况影响，当室外温度增大时，建筑热负荷减少，反之室外温度减小时，建筑热负荷增大。而风机盘管换热能力与室外工况无关，受水流量、供水温度等影响，在保持室内温度即风盘回风温度不变及水流量不变的情况下，风机盘管换热能力随供水温度升高而增大，降低而减小。当室外温度从T1升高到T2时，建筑热负荷从Q1减少到Q2，若供水温度仍然保持不变，会造成风机盘管换热能力大于建筑负荷需求，导致室内过热，反映到系统上是冷冻水总供回水温差减小，反之亦然。针对变频系统可以通过优先调节水流量，当水流量调节至极限再进行出水温度的调节。水流量的调节方案较为常规，因此下面对机组出水温度的调控逻辑进行介绍。
图2是根据本申请实施例的热泵系统的出水温度调控方法的流程图，如图2所示，在本申请的一实施例中，该方法包括以下步骤S201至S203。
步骤S201，监测变频水泵的运行频率，以及，监测冷冻总管的供回水温差。
具体地，变频水泵的运行频率可以通过主机读取数据的方式来确定。热泵系统中的多个变频水泵是同频运行。冷冻总管的供回水温差＝分水器的供水管的温度－集水器的回水管的温度，分水器的供水管连接至热泵机组，热泵机组与集水器之间的回水管上设置有变频水泵，在具体实现时，分别获取分水器的供水管的温度数据和集水器的回水管的温度数据，根据分水器的供水管的温度数据、集水器的回水管的温度数据，得到冷 冻总管的供回水温差。
步骤S202，判断变频水泵的运行频率与预设频率范围的关系，以及，判断供回水温差与预设温差范围的关系；
步骤S203，根据判断结果采取对应的调控策略调整热泵机组的出水温度。
具体地，如果判断结果为第一结果：变频水泵的运行频率大于或等于预设频率范围的最大值，以及，供回水温差大于或等于预设温差范围的最大值，则对应的调控策略为：升高热泵机组的出水温度。如果判断结果为第二结果：变频水泵的运行频率小于预设频率范围的最小值，以及，供回水温差小于预设温差范围的最小值，则对应的调控策略为：降低热泵机组的出水温度。如果判断结果是除第一结果和第二结果之外的判断结果，所对应的调控策略为：保持热泵机组的出水温度不变。基于此，可以实现空气源热泵采暖系统的供热量按需供应，减少供热浪费，提升系统整体能耗，实现高效节能，极大满足用户的采暖舒适要求。
为了避免对热泵机组的出水温度的频繁调节或无效调节，本申请的一实施例在设置了上述第一结果和第二结果这两个条件的基础上，还设置了持续时间这一参数。具体地，如果判断结果为第一结果且持续时间超过预设时长，则升高热泵机组的出水温度；如果判断结果为第二结果且持续时间超过预设时长，则降低热泵机组的出水温度；如果判断结果既不是所述第一结果且持续时间超过预设时长，又不是所述第二结果且持续时间超过预设时长，则保持热泵机组的出水温度不变。基于此，能够避免对出水温度的频繁调节。需要说明的是，对于热泵机组的出水温度的调节，即是对热泵机组的预设出水温度的调节，在升高、降低或保持出水温度之后，则将调整后的出水温度作为预设出水温度。
需要说明的是，出水温度的调整需要保证其在一个合理范围内，即调整后的出水温度不能低于出水温度的设定下限值(例如35℃)，不能高于出水温度的设定上限值(例如50℃)。从而保证系统的正常运行。
需要说明的是，在执行本实施例介绍的出水温度调控方案之前，需要确定热泵机组是否在运行中，即，确定热泵系统的热泵机组的运行数量；如果运行数量大于或等于一台，则触发监测变频水泵的运行频率以及监测冷冻总管的供回水温差，如果运行数量为零，则无法执行出水温度调控方案。
本实施例介绍的出水温度调控方案可以设置为周期性执行，即，在预设间隔时长 后，重新监测变频水泵的运行频率，以及，监测冷冻总管的供回水温差；判断变频水泵的运行频率与预设频率范围的关系，以及，判断供回水温差与预设温差范围的关系；根据判断结果采取对应的调控策略调整热泵机组的出水温度。以上作为一个出水温度调控周期，在每个出水温度调控周期内，对于出水温度的调整(升高或降低)都可以按照预设重设梯度执行，即在一个出水温度调控周期内，对出水温度升高一个预设重设梯度或降低一个预设重设梯度。从而实现对空气源热泵采暖系统的长期稳定的调控。
图3是根据本申请另一实施例的热泵系统的出水温度调控方法流程图，如图3所示，本申请的另一实施例的热泵系统的出水温度调控方法包括以下步骤：
步骤S301，判断系统内热泵机组的运行台数是否大于1台，如果是则执行步骤S303，如果否则执行步骤S302；

步骤S305，判断冷冻总管的供回水温差是否大于温差设定值和偏差设定值之和；例如，预先设置一个温差设定值(例如5℃)和一个偏差设定值，将温差设定值和偏差设定值之和作为预设温差范围的最大值，将温差设定值与偏差设定值之差作为预设温差范围的最小值；上述温差设定值等于冷冻总管出水温度设定值与运行机组回水温度设定值之差；如果是则执行步骤S306，如果否则执行步骤S308；
步骤S306，判断持续时间是否大于预设时长(例如30s)，如果是则执行步骤S307，如果否则执行步骤S309；
步骤S307，升高热泵机组的出水温度，例如将机组的出水温度升高一个预设重设梯度；在预设间隔时长(例如1800s)后，返回重新执行步骤S303；
步骤S308，热泵机组的出水温度保持不变；在预设间隔时长(例如1800s)后，返回重新执行步骤S303；
步骤S309，热泵机组的出水温度保持不变；在预设间隔时长(例如1800s)后，返 回重新执行步骤S303；
步骤S310，判断水泵频率是否小于变频水泵最小频率(即预设频率范围的最小值)，如果是则执行步骤S312，如果否则执行步骤S311；
考虑到频率的浮动范围，可以设置预设频率范围的最小值是变频水泵最小频率(例如35Hz)与机组出水温度重设水泵频率调节值之和；
步骤S311，热泵机组的出水温度保持不变；在预设间隔时长(例如1800s)后，返回重新执行步骤S303；
步骤S312，判断冷冻总管的供回水温差是否小于温差设定值与偏差设定值之差；如果是则执行步骤S314，如果否则执行步骤S313；
步骤S313，热泵机组的出水温度保持不变；在预设间隔时长(例如1800s)后，返回重新执行步骤S303；
步骤S314，判断持续时间是否大于预设时长(例如30s)，如果是则执行步骤S316，如果否则执行步骤S315；
步骤S315，热泵机组的出水温度保持不变；在预设间隔时长(例如1800s)后，返回重新执行步骤S303；
步骤S316，降低热泵机组的出水温度，例如将机组的出水温度降低一个预设重设梯度；在预设间隔时长(例如1800s)后，返回重新执行步骤S303。
需要说明的是，上述流程中，对于水泵频率的判断(步骤S304)和对于冷冻总管的供回水温差的判断(步骤S305)的执行顺序可以调换，图3只是示例性说明，不作限制。
