技术领域
本申请涉及设备降温技术领域，尤其涉及一种液冷机组及其控制方法。
背景技术
在一些放置设备的机房内，由于设备运行时会产生热量，持续产生的热量会导致机房内的环境温度升高，影响机房内的设备正常运行，机房内的设备运行故障率升高，因此需要对机房内的设备进行持续高效的降温，保障设备始终处于适宜的温度下工作。
相关技术中存在一种机房制冷系统，包括机柜柜体和室外冷源单元，其特征在于，机柜柜体为封闭柜体，封闭柜体内部布置电子设备，电子设备的一侧区域设有冷却管路，冷却管路的进液端和出液端分别连通室外冷源单元，室外冷源单元为水冷模块，通过循环水流经冷却管路对封闭柜体内的电子设备进行降温，并将封闭柜体内的热量通过循环水传导到室外冷源单元内；在室外环境温度较低时，在水冷模块上配置电加热来对冻结的循环水加热，以使循环水能够正常循环对封闭柜体降温。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
通过电加热对低温环境下的循环水进行加热的方式，增大了能耗，提高了成本；而且电加热难以精确地控制循环水的温度，影响封闭柜体内的降温效果。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本申请的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。
发明内容
为了对披露的实施例的一些方面有基本的理解，下面给出了简单的概括。所述概括不是泛泛评述，也不是要确定关键/重要组成元素或描绘这些实施例的保护范围，而是作为后面的详细说明的序言。
本公开实施例提供一种液冷机组及其控制方法，以降低能耗，减小液冷机组的降温成本，精准的调节低温环境下换热介质的温度，保障换热介质的降温效果。
在一些实施例中，液冷机组，包括：蒸发器、冷凝器、回液管路和出液管路。回液管路包括第一流路和第二流路，第一流路流经蒸发器，第二流路流经冷凝器；出液管路分别与第一流路和第二流路的出液端连通，换热介质沿回液管路和出液管路循环流通。
在一些实施例中，液冷机组的控制方法，包括：
获取液冷机组所处的环境温度；
根据环境温度与第一设定温度的大小关系控制液冷机组中换热介质的流向。
本公开实施例提供的液冷机组及其控制方法，可以实现以下技术效果：

需要说明的是，在不冲突的情况下，本公开实施例中的实施例及实施例中的特征可以相互组合。
结合图1-3所示，本公开实施例提供一种液冷机组，包括：蒸发器200、冷凝器300、回液管路400和出液管路500。回液管路400包括第一流路410和第二流路420，第一流 路410流经蒸发器200，第二流路420流经冷凝器300；出液管路500分别与第一流路410和第二流路420的出液端连通，换热介质沿回液管路400和出液管路500循环流通。
采用本公开实施例提供的液冷机组，换热介质从出液管路500流出对需要散热的模块进行降温散热，温度升高后的换热介质从回液管路400流入，通过第一流路410流经蒸发器200进行降温冷却后再次从出液管路500流出进行降温散热。当该液冷机组所处的环境温度较低时，此时低温环境下的换热介质流通可能受到影响，因此选择性地控制换热介质的流向，在低温使用时使换热介质通过第二流路420流经冷凝器300，利用冷凝器300对换热介质加热，保障换热介质能够通畅地流通，降低了能耗，减小了该液冷机组的成本。通过冷凝器300对低温环境下的换热介质加温，并根据环境温度控制换热介质的流向，能够精准地调节低温环境下换热介质的温度，保障换热介质的降温效果。
可选地，该液冷机组还包括：压缩机600。压缩机600具有排气管和回气管，排气管与冷凝器300的输入端连通，回气管与蒸发器200的输出端连通。这样，通过压缩机600将冷媒压缩为高温高压的气态冷媒通过排气管排出到冷凝器300内，高温高压的气态冷媒在冷凝器300内冷凝放热。当该液冷机组运行在低温环境下时，使换热介质通过第二流路420流经冷凝器300，通过冷凝器300对流经的换热介质进行加热，保障换热介质正常流通。通过调节冷凝器300的冷凝温度来精准的控制换热介质的加热温度，既能够对低温环境下的换热介质加热，又能够避免加热温度过高影响换热介质的降温散热效果。冷凝放热后的冷媒流向蒸发器200蒸发吸热，通过回液管路400回流的换热介质温度升高，在非低温环境时控制换热介质通过第一流路410流经蒸发器200，利用蒸发器200吸收换热介质的热量，使换热介质能够再次流出进行降温散热。
具体的，冷凝器300的输出端与蒸发器200的输入端连通。这样，冷凝器300中冷凝放热后的冷媒从输出端流向蒸发器200的输入端，流入蒸发器200中的冷媒在蒸发器200中蒸发吸热，蒸发吸热后的气态冷媒从回气管流入压缩机600内再次压缩，完成一个冷媒循环。
具体的，冷凝器300的输出端和蒸发器200的输入端之间连通有节流装置700。这样，通过节流装置700对冷凝器300流出的冷媒进行节流降压，使流入蒸发器200中的冷媒更好的蒸发吸热。
具体的，换热介质为水，该液冷机组为水冷机组。
可选地，如图2所示，该液冷机组还包括：冷却管路800。冷却管路800设置在设备中，用于对设备进行降温，冷却管路800的一端连通出液管路500，另一端连通回液管路400，换热介质在冷却管路800、回液管路400以及出液管路500之间循环流通。这样，出 液管路500流出的换热介质流入冷却管路800中，由于冷却管路800布置在需要散热降温的设备中，流入冷却管路800中的换热介质吸收设备产生的热量，对设备进行降温散热。吸收热量的换热介质流入回液管路400中，通过第一流路410流入蒸发器200中进行降温制冷，便于后续再次流入冷却管路800中降温散热。但在环境温度较低时，换热介质可通过第二流路420流向冷凝器300中加热，保障换热介质的顺利流通。
可以理解的，设备为机房中的服务器、终端等发热设备，冷却管路800可布置在设备内，也可布置在机房内，对机房内的环境进行降温。
可选地，回液管路400还包括主回液管430，主回液管430分别连通第一流路410和第二流路420的进液端。这样，冷却管路800中的换热介质在吸收了热量后流入主回液管430中，然后根据环境温度的高低来控制主回液管430内的换热介质流入第一流路410或第二流路420中，从而控制换热介质流向蒸发器200降温或流向冷凝器300加热，更好的控制回液管路400中换热介质的流向。
示例性的，主回液管430的出液端分别与第一流路410第二流路420的进液端连通，形成三通的形式，主回液管430内的换热介质能够选择性地流向第一流路410或第二流路420。
可选地，主回液管430与第一流路410和第二流路420连通的位置设有三通电磁阀440，能够在导通第一流路410的同时封堵第二流路420，或在封堵第一流路410的同时导通第二流路420。这样，通过三通电磁阀440控制第一流路410和第二流路420的导通和关闭，从而更精确地控制主回液管430内换热介质的流向。在需要控制主回液管430内的换热介质流向蒸发器200降温时，控制三通电磁阀440来导通第一流路410，封堵第二流路420，使主回液管430内的换热介质流向蒸发器200进行降温。在需要控制主回液管430内的换热介质流向冷凝器300加热时，控制三通电磁阀440来封堵第一流路410，导通第二流路420，使主回液管430内的换热介质流向冷凝器300加热。
具体的，三通阀具有输入端和两个输出端，输入端连通主回液管430的出液端，两个输出端中的一个连通第一流路410的进液端，另一个连通第二流路420的进液端。
可选地，如图1所示，该液冷机组还包括：温度传感器900。温度传感器900设置于蒸发器200所处的环境中，温度传感器900与三通电磁阀440电连接。这样，通过温度传感器900能够实时获取环境温度，根据环境温度的高低来控制三通电磁阀440的导通状态，从而控制主回液管430内换热介质的流向。由于蒸发器200用于对换热介质降温制冷，因此将温度传感器900设置在蒸发器200所处的环境中，利用温度传感器900实时检测蒸发器200所处的环境温度，从而更精准地判断此时换热介质所处的环境温度需不需要对换热 介质进行加热。
结合图3所示，在一个实施例中，蒸发器200的冷媒盘管分为第一外层管210和第一内层管220，第一外层管210套设在第一内层管220外周，在第一外层管210的内周壁与第一内层管220的外周壁之间限定出第一流通空间230，蒸发器200的冷媒在第一流通空间230内流通，第一内层管220连通于第一流路410中。这样，将蒸发器200的冷媒盘管设置为第一外层管210包裹第一内层管220，蒸发器200中的冷媒在第一流通空间230内流通，换热介质在第一内层管220中流通，使蒸发吸热的冷媒对换热介质形成包裹的效果，提高换热面积和换热效率。在换热介质需要流经蒸发器200降温冷却时，能够提高换热介质的冷却效率。
可选地，第一外层管210和第一内层管220均为圆管，且第一外层管210和第一内层管220同心设置。这样，使第一外层管210的内周壁和第一内层管220的外周壁之间限定出的第一流通空间230更均匀，冷媒更顺畅地在第一流通空间230内流通，从而更好地与第一内层管220内流通的换热介质换热。
示例性的，第一流路410中流通的换热介质在流经蒸发器200时，先流入第一内层管220的进液端，然后从第一内层管220的出液端再次流出到第一流路410中，换热介质在流经蒸发器200时全程均参与换热。
可选地，冷凝器300的冷媒盘管分为第二外层管310和第二内层管320，第二外层管310套设在第二内层管320外周，在第二外层管310的内周壁与第二内层管320的外周壁之间限定出第二流通空间330，冷凝器300的冷媒在第二流通空间330内流通，第二内层管320连通于第二流路420中。这样，将冷凝器300的冷媒盘管设置为第二外层管310包裹第二内层管320，冷凝器300中的冷媒在第二流通空间330内流通，换热介质在第二内层管320中流通，使冷凝放热的冷媒对换热介质形成包裹的效果，提高换热面积和换热效率。在换热介质需要流经冷凝器300加热方凝结时，能够提高换热介质的加热效率。
可选地，第二外层管310和第二内层管320均为圆管，且第二外层管310和第二内层管320同心设置。这样，使第二外层管310的内周壁和第二内层管320的外周壁之间限定出的第二流通空间330更均匀，冷媒更顺畅地在第二流通空间330内流通，从而更好地与第二内层管320内流通的换热介质换热。
示例性的，第二流路420中流通的换热介质在流经冷凝器300时，先流入第二内层管320的进液端，然后从第二内层管320的出液端再次流出到第二流路420中，换热介质在流经冷凝器300时全程均参与换热。
结合图4所示，在一些实施例中，液冷机组的控制方法，包括：
S01，处理器获取液冷机组所处的环境温度；
S02，处理器根据环境温度与第一设定温度的大小关系控制液冷机组中换热介质的流向。
采用本公开实施例提供的液冷机组的控制方法，换热介质从出液管路流出对需要散热的模块进行降温散热，温度升高后的换热介质从回液管路流入，通过第一流路流经蒸发器进行降温冷却后再次从出液管路流出进行降温散热。当该液冷机组所处的环境温度较低时，此时低温环境下的换热介质流通可能受到影响，因此选择性地控制换热介质的流向，在低温使用时使换热介质通过第二流路流经冷凝器，利用冷凝器对换热介质加热，保障换热介质能够通畅地流通，降低了能耗，减小了该液冷机组的成本。通过冷凝器对低温环境下的换热介质加温，并根据环境温度控制换热介质的流向，能够精准地调节低温环境下换热介质的温度，保障换热介质的降温效果。
可选地，处理器获取液冷机组所处的环境温度包括：处理器获取液冷机组中蒸发器所处的环境温度。这样，由于在该液冷机组中蒸发器用来冷却换热介质，因此获取蒸发器所处的环境温度，能够更直观地反映出换热介质所处的环境温度，根据蒸发器所处的环境温度来控制换热介质的流向，更精准的控制换热介质的流向，提高该液冷机组运行的稳定性。
可选地，处理器获取液冷机组中蒸发器所处的环境温度包括：处理器获取蒸发器所处环境中设置的温度传感器发送的环境温度。这样，处理器通过获取温度传感器发送的环境温度，能够简化环境温度获取的过程，提高环境温度获取的精度。
可选地，处理器根据环境温度与第一设定温度的大小关系控制液冷机组中换热介质的流向，包括：处理器根据环境温度与第一设定温度的大小关系控制回液管路中三通电磁阀的导通状态。这样，由于换热介质的流向通过三通电磁阀来控制，因此处理器根据环境温度与第一设定温度的大小关系来控制三通电磁阀的导通状态，从而更精准高效的控制换热介质的流向。
具体的，三通电磁阀的导通状态包括：第一导通状态和第二导通状态；其中，在第一导通状态下导通第一流路的同时封堵第二流路，在第二导通状态下封堵第一流路的同时导通第二流路。
结合图5所示，在一些可选地实施例中，液冷机组的控制方法，包括：
S01，处理器获取液冷机组所处的环境温度；
S021，处理器在环境温度大于或等于第一设定温度的情况下，控制换热介质流向蒸发器。
采用本公开实施例提供的液冷机组的控制方法，在获取的环境温度大于或等于第一设 定温度时，此时环境的温度相对较高，换热介质能够在该液冷机组中顺畅地流通。而在换热介质吸收热量温度升高时，需要对换热介质进行降温来保障换热介质的降温效果，因此控制换热介质流向蒸发器，利用蒸发器来对温度升高的换热介质进行降温。
具体的，处理器控制换热介质流向蒸发器，包括：处理器控制回液管路中的三通电磁阀处于第一导通状态。这样，三通电磁阀处于第一导通状态时，第一流路导通，第二流路封堵，换热介质通过第一流路流向蒸发器中降温冷却。
结合图6所示，在一些可选地实施例中，液冷机组的控制方法，包括：
S01，处理器获取液冷机组所处的环境温度；
S022，处理器在环境温度小于第一设定温度的情况下，控制换热介质流向冷凝器。
采用本公开实施例提供的液冷机组的控制方法，在获取的环境温度小于第一设定温度时，此时环境温度较低，该液冷机组中的换热介质存在凝结的风险，因此控制换热介质流向冷凝器进行加热，保障换热介质的顺畅流通。由于此时环境温度较低，即使被冷凝器加热的换热介质也远低于设备内部的温度，从而在流经布置在设备内的冷却管路时对设备散热。
具体的，处理器控制换热介质流向冷凝器，包括：处理器控制回液管路中的三通电磁阀处于第二导通状态。这样，三通电磁阀在第二导通状态时封堵第一流路，导通第二流路，从而使换热介质通过第二流路流入冷凝器中进行加热。
具体的，第一设定温度为2℃。这样，在环境温度大于或等于2℃时，此时换热介质无凝结风险，因此控制吸热后的换热介质流向蒸发器进行降温。在环境温度小于2℃时，此时换热介质存在凝结风险，因此控制吸热后的换热介质流向冷凝器进行加热。
结合图7所示，在一些可选地实施例中，液冷机组的控制方法，包括：
S01，处理器获取液冷机组所处的环境温度；
S022，处理器在环境温度小于第一设定温度的情况下，控制换热介质流向冷凝器；
S03，处理器确定环境温度与第二设定温度之间的大小关系；
S04，处理器在环境温度大于或等于第二设定温度的情况下，控制液冷机组的压缩机停机；
其中，第二设定温度小于第一设定温度。
采用本公开实施例提供的液冷机组的控制方法，处理器在控制换热介质流向冷凝器后，再次确定环境温度与第二设定温度之间的大小关系。由于第二设定温度小于第一设定温度，在环境温度大于或等于第二设定温度，且小于第一设定温度的情况下，此时环境温度虽然相对较低，但此时换热介质的凝结风险较小，无需对换热介质进行加热的同时。可利用相 对较低的环境温度对换热介质进行冷却，因此控制压缩机停机，利用换热介质流经冷凝器时与环境换热进行冷却，在保障换热介质降温散热效果的同时，进一步降低能耗。
可选地，处理器在环境温度大于或等于第二设定温度的情况下，控制液冷机组的压缩机停机的同时，控制冷凝风机的转速提高。这样，在处理器控制压缩机停机时，为提高流经冷凝器与环境换热的换热介质的换热效率，控制冷凝风机的转速提高，从而加快冷凝器中换热介质与环境之间的换热，提高换热介质的冷却效率。
具体的，第二设定温度为零下6℃。这样，在环境温度大于或等于零下6℃的情况下，换热介质虽然存在凝结风险，但风险相对较小，为降低能耗可控制压缩机停机。在环境温度小于零下6℃的情况下，此时环境温度较低，换热介质的凝结风险相对较高。
结合图8所示，在一些可选地实施例中，液冷机组的控制方法，包括：
S01，处理器获取液冷机组所处的环境温度；
S022，处理器在环境温度小于第一设定温度的情况下，控制换热介质流向冷凝器；
S03，处理器确定环境温度与第二设定温度之间的大小关系；
S05，处理器在环境温度小于第二设定温度的情况下，控制液冷机组的压缩机以设定功率运行。
采用本公开实施例提供的液冷机组的控制方法，处理器在控制换热介质流向冷凝器后，确定环境温度与第二设定温度之间的大小关系，在环境温度小于第二设定温度时，此时换热介质的凝结风险较高，因此控制压缩机运行，通过冷凝器对流经的换热介质进行加热，保障换热介质的顺畅流通。由于流经冷凝器后的换热介质需要流向设备进行降温散热，因此冷凝器的加热温度不宜过高，因此控制压缩机以设定功率运行，使冷凝器既能够对换热介质进行适当的加热，保障其流通的顺畅性，又能够保障换热介质在被加热后依然具有较好的降温散热效果。
具体的，在压缩机以设定功率运行的情况下，流经冷凝器后的换热介质的温度在大于或等于6℃，且小于或等于10℃的范围内波动。这样，使被冷凝器加热后的换热介质的温度在6至10℃之间，具有良好的流通性的同时，具有较好的降温散热效果。
结合图9所示，本公开实施例提供一种液冷机组的控制装置，包括处理器(processor)100和存储器(memory)101。可选地，该装置还可以包括通信接口(Communication Interface)102和总线103。其中，处理器100、通信接口102、存储器101可以通过总线103完成相互间的通信。通信接口102可以用于信息传输。处理器100可以调用存储器101中的逻辑指令，以执行上述实施例的液冷机组的控制方法。
此外，上述的存储器101中的逻辑指令可以通过软件功能单元的形式实现并作为独立 的产品销售或使用时，可以存储在一个计算机可读取存储介质中。
