为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例进行描述。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”或“具有”及其任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参阅图1，本发明实施例提供的泳池热泵系统的水温控制方法的流程图，具体包括：
101、获取外部环境温度并根据外部环境温度对加热温度进行调整，得到目标加热温度。
终端获取外部环境温度并根据外部环境温度对加热温度进行调整，得到目标加热温度。
需要说明的是，热泵系统可以应用在泳池水加热场景中，针对泳池内部水温和外部环境温度进行实时调整目标加热温度，以满足使用需求：1、泳池未投入使用前，泳池内部水温较低，此时会有两种需求，其一是希望泳池内部的温度尽量快速的达到设定温度。其二是预约加热，时间可以相对较长，希望能耗小。2、泳池热泵加热泳池水温能够上下波动小，人体感觉舒适。3、泳池水温能够跟随外界环境温度而自动调节，例如，当外部环境温度较高时(即天气较热)时，水温可以比平时温度设定低一点，可以让人体感觉更舒适，同时也更节能；当外界环境温度较低(即天气较冷)时，目标加热温度可以设定比平时高一点。
可以理解的是，本发明的执行主体可以为泳池热泵系统的水温控制装置，还可以是终端，具体此处不做限定。本发明实施例以终端为执行主体为例进行说明。
102、检测泳池热泵系统的进水温度，并确定进水温度与目标加热温度之间的温差绝对值。
终端检测泳池热泵系统的进水温度，并确定进水温度与目标加热温度之间的温差绝对值。其中，温差绝对值为目标加热温度减去进水温度得到的差值取绝对值。
可以理解的是，不同的温差绝对值，对应的热泵系统的工作频率也不同，因此通过设定不同温差范围，分别划定不同的加热方式。
103、根据温差绝对值确定泳池热泵系统的目标工作频段，并控制泳池热泵系统中的变频压缩机基于目标工作频段对待加热容器内的水进行加热，通过循环泵将待加热容器内已加热的水置换到泳池中。
具体的，若温差绝对值大于或等于第一温差阈值，则终端确定泳池热泵系统中的变频压缩机进入快速加热阶段，快速加热阶段用于指示泳池热泵系统的目标工作频段为高频工作频段；若温差绝对值大于或等于第二温差阈值且小于第一温差阈值，则终端确定变频压缩机进入节能加热阶段，节能加热阶段用于指示泳池热泵系统的目标工作频段为中频工作频段；若温差绝对值小于第二温差阈值，则终端确定变频压缩机进入恒温维持阶段，恒温维持阶段用于指示泳池热泵系统的目标工作频段为低频工作频段；终端控制变频压缩机基于高频工作频段、中频工作频段或低频工作频段对待加热容器内的水进行加热，然后通过循环泵将待加热容器内已加热的水置换到泳池中，不断提高泳池内的水温，以使得泳池内的水温维持在目标加热温度。
本发明实施例，根据外部环境温度调整目标加热温度，进而根据标加热温度调整泳池水温，提高泳池热泵系统工作时的性能系数，降低能耗，避免泳池热泵系统频繁开启和关闭，提高了泳池热泵系统的使用寿命。
请参阅图2，本发明实施例提供的泳池热泵系统的水温控制方法的另一个流程图，具体包括：
201、获取外部环境温度并根据外部环境温度对加热温度进行调整，得到目标加热温度。
具体的，终端通过预置的环境温度传感器检测当前的外部环境温度；若外部环境温度小于或等于第一环境温度阈值，则终端将第一预设温度确定为目标加热温度；若外部环境温度大于第一环境温度阈值且小于或等于第二环境温度阈值，则终端按照预置的曲线确定对应的目标加热温度，预置的曲线用于指示目标加热温度与环境温度之间的反比关系；若外部环境温度大于第二环境温度阈值，则终端将第二预设温度确定为目标加热温度，第二预设温度小于第一预设温度。
需要说明的是，泳池热泵系统为应用在泳池水加热场景中，针对泳池内部水温和外部环境温度进行实时调整目标加热温度，以满足使用需求：1、泳池未投入使用前，泳池内部水温较低，此时会有两种需求，其一是希望泳池内部的温度尽量快速的达到设定温度。其二是预约加热，时间可以相对较长，希望能耗小。2、泳池热泵加热泳池水温能够上下波动小，人体感觉舒适。3、泳池水温能够跟随外界环境温度而自动调节，例如，当外部环境温度较高时 (即天气较热)时，水温可以比平时温度设定低一点，可以让人体感觉更舒适，同时也更节能；当外界环境温度较低(即天气较冷)时，目标加热温度可以设定比平时高一点。外部环境温度越高，设定的目标加热温度越低，目标加热温度与外部环境温度在预置范围内成反比关系，该预置范围为第一预设温度至第二预设温度，其中，第一预设温度大于第二预设温度。
其中，预置的曲线的斜率为K，如图3所示，
Figure PCTCN2021073514-appb-000003
其中，TT1为第一预设温度，TT2为第二预设温度，AT1为第一环境温度阈值，AT2为第二环境温度阈值，即预设温度差为第一预设温度和第二预设温度之间的差值，环境温度差为第一环节温度和第二环境温度之间的差值，预设温度差与环境温度差之间成反比例关系，K的取值范围可以为[-2，-0.5]。具体的，当外部环境温度大于AT2时，泳池热泵系统的变频压缩机以TT2为目标加热温度运行。当外部环境温度大于AT1且小于或等于AT2时，泳池热泵系统的变频压缩机按预置的曲线确定的值为目标加热温度运行。当外部环境温度小于或等于AT1时，泳池热泵系统的变频压缩机以TT1为目标加热温度运行。或者，预置的曲线为弧形(向左下角凸起)，且曲线的斜率K随环境温度的增加而增加，即外部环境温度越高，目标加热温度变化速率越慢，外部环境温度越低，目标加热温度变化速率越快。
通过上述对目标加热温度的修正，根据泳池热泵系统原理，目标加热温度每差1℃时，泳池热泵系统的性能参数COP相差2～3％左右，水温越低时，COP越高。因此本实施例能够提高泳池热泵系统在较高环境温度的情况下，获得更高的能效，进一步降低能耗。
202、检测泳池热泵系统的进水温度，并确定进水温度与目标加热温度之间的温差绝对值。
具体的，检测泳池热泵系统的进水温度，将目标加热温度减去泳池热泵系统的进水温度得到差值，并对差值取绝对值。不同的温差绝对值，对应的泳池热泵系统的工作频率也不同，因此通过设定不同温差范围，分别划定不同的加热方式。
其中，泳池热泵系统的进水温度可以低于或等于目标加热温度，也可以高于目标加热温度，当泳池热泵系统的进水温度低于或等于目标加热温度时，则差值为正值，其绝对值也为正值；当泳池热泵系统的进水温度高于目标加热温度时，即泳池水温过高，则差值为负数，必须取绝对值从而得到正值。
203、判断温差绝对值是否小于第一温差阈值。
终端判断温差绝对值是否小于第一温差阈值。
204、若温差绝对值大于或等于第一温差阈值，则确定泳池热泵系统中的变频压缩机进入快速加热阶段，快速加热阶段用于指示泳池热泵系统的目标工作频段为高频工作频段。
若温差绝对值大于或等于第一温差阈值，则终端确定泳池热泵系统中的变频压缩机进入快速加热阶段，快速加热阶段用于指示热泵系统的目标工作 频段为高频工作频段。例如，第一温差预置为3℃，当温差绝对值大于或等于3℃时，可以确定离目标温度的温差较大，此时需要快速给泳池水温加热，让温差尽快减小。假设，当终端确定了目标加热温度为30℃后，泳池热泵系统开启循环水温，检测当前热泵的进水温度Ti为20℃，温差绝对值为10℃，离目标加热温度30℃的温差较大，此时需要快速给泳池水温加热，让温差尽快减小。当温差绝对值大于或等于3℃时，进入快速加热阶段，在此阶段，变频压缩机处于高频段运行，通常按照最大制热量的80％～120％输出，即[0.8Q，1.2Q]，且COP运行范围为4≤COP≤5，其中，Q为泳池热泵系统的最大制热量。
205、若温差绝对值小于第一温差阈值，则判断温差绝对值是否小于第二温差阈值。
若温差绝对值小于第一温差阈值，则终端继续判断温差绝对值是否小于第二温差阈值。例如，第一温差预置为3℃，第二温差阈值为0.5℃。
206、若温差绝对值大于或等于第二温差阈值且小于第一温差阈值，则确定泳池热泵系统中的变频压缩机进入节能加热阶段，节能加热阶段用于指示泳池热泵系统的目标工作频段为中频工作频段。
若温差绝对值大于或等于第二温差阈值且小于第一温差阈值，则终端确定泳池热泵系统中的变频压缩机进入节能加热阶段，节能加热阶段用于指示泳池热泵系统的目标工作频段为中频工作频段。
例如，当温差绝对值大于0.5℃且小于或等于3℃时，进入节能加热阶段，在此阶段，泳池热泵系统中的变频压缩机处于中频段运行，通常按照最大制热量的40％～80％输出，即(0.4Q，0.8Q)，且COP运行范围为5＜COP＜7。
207、若温差绝对值小于第二温差阈值，则确定泳池热泵系统中的变频压缩机进入恒温维持阶段，恒温维持阶段用于指示泳池热泵系统的目标工作频段为低频工作频段。
若温差绝对值小于第二温差阈值，则终端确定泳池热泵系统中的变频压缩机进入恒温维持阶段，恒温维持阶段用于指示泳池热泵系统的目标工作频段为低频工作频段。
当温差绝对值小于0.5℃时，进入能恒温维持阶段，在此阶段，变频压缩机处于低频段运行，通常按照最大制热量的5％～40％输出，即[0.05Q，0.4Q]，且COP运行范围为7≤COP≤8。其中，当温差绝对值小于0.5℃，且目标加热温度大于泳池水温的实际温度时，按照最大制热量的5％～20％(包括5％但不包括20％)进行输出，当温差绝对值小于0.5℃，且目标加热温度大于泳池水温的实际温度时，按照最大制热量的20％～40％(包括20％和40％)进行输出。需要说明的是，当按照最大制热量的5％进行制热时，泳池热泵系统对应的COP为8，当按照最大制热量的40％进行制热时，泳池热泵系统对应的COP为7。
需要说明的是，在高频工作频段、中频工作频段或低频工作频段中，终端还可以实时调整变频压缩机的运行频率，逐渐降低实际运行频率，以使得COP一直处于最大值。
208、控制变频压缩机基于高频工作频段、中频工作频段或低频工作频段 对待加热容器内的水进行加热，通过循环泵将所述待加热容器内已加热的水置换到泳池中。
具体的，终端根据温差绝对值的变化调整所述变频压缩机的实时工作频率，根据所述实时工作频率对待加热容器内的水进行加热，所述实时工作频率为所述高频工作频段、所述中频工作频段或所述低频工作频段；当所述变频压缩机运行在所述高频工作频段时，终端确定所述泳池热泵系统的当前制热量的取值范围为[0.8Q，1.2Q]，所述泳池热泵系统对应的性能系数COP的取值范围为4≤COP≤5，其中，Q为所述泳池热泵系统的最大制热量；当所述变频压缩机运行在所述中频工作频段时，终端确定所述泳池热泵系统的当前制热量的取值范围为(0.4Q，0.8Q)，所述泳池热泵系统对应的性能系数COP的取值范围为5＜COP＜7；当所述变频压缩机运行在所述低频工作频段时，终端确定所述泳池热泵系统的当前制热量的取值范围为[0.05Q，0.4Q]，所述泳池热泵系统对应的性能系数COP的取值范围为7≤COP≤8，如图4所示。
在温差较大(不小于第一温差阈值)时，终端先控制变频压缩机运行高频工作频段，随着变频压缩机的工作，温差逐渐缩小(小于第二温差阈值)，控制变频压缩机运行中频工作频段，当温差维持在目标加热温度的周围(例如，目标加热温度的正负0.5℃)时，控制变频压缩机运行低频工作频段并维持，以使得热泵系统在各个运行阶段，COP为最大值。
本实施例，充分利用泳池热泵系统中变频压缩机可以调节制热量输出的特点，根据泳池实际水温情况，在低温区间时通过提高压缩机转速，获得最大的制热量，使水温快速提升，由于此时水温较低，冷凝温度较小，COP维持在较高的水平。随着水温提升到中温区间，此时冷凝效率下降，如果还维持较高转速时，COP会下降，因此通过降低压缩机转速(降低频率)，使压缩机排气量下降，充分利用蒸发器和冷凝器换热面积，以此来弥补水温身高带来的COP下降问题，同时在满足水温持续上升的前提下，尽量使用较低的频率运行，获取最大的COP。在中温区间随着水温上升，压缩机频率会进一步下降，最终水温达到目标温度时，此时压缩机频率刚好输出最合适的频率，使泳池热泵提供的热量正好平衡泳池水温与外界的散热损耗，此时泳池水温不会再持续大温差升温，处于±0.5℃范围内波动。
需要说明的是，本实施例中，泳池热泵系统的变频压缩机不会停机，始终以较低的频率维持。此时可以获取最大的COP，并且泳池水温不会有大的水温波动，人体感觉更舒适，避免了频繁开启关闭对零部件的寿命损伤。
本发明实施例，根据外部环境温度调整目标加热温度，进而根据标加热温度调整泳池水温，提高泳池热泵系统工作时的性能系数，降低能耗，避免泳池热泵系统频繁开启和关闭，提高了泳池热泵系统的使用寿命。
