 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，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作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者系统不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者系统所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者系统中还存在另外的相同要素。

为使本申请中各控制方法的实施方式所涉及的技术方案更清楚，本申请现提出一种空调器。参照图1和图2，图1为本申请实施例方案涉及的空调器第一机箱的结构示意图；图2为本申请实施例方案涉及的空调器第二机箱的结构示意图。
如图1和图2所示，空调器包括第一机箱1和第二机箱2。其中，第一机箱1包括进风管11、排风管12、第一换热器13、压缩机14和水箱15，水箱15内设置有水箱换热器16。第二机箱2包括流量调节泵21和第二换热器22。第二机箱2中的流量调节泵21通过水管与第一机箱1中的水箱15连接。第一机箱1和第二机箱2通常均设置在室内，并通过进风管11和排风管12连通室外环境。当然第一机箱也可以直接设置在室外。
第一机箱1还设置有第一风机，该第一风机运行时通过进风管11吸入室外空气，然后在通过排风管12排出至室外。空气在第一机箱1内流经第一换热器13，从而与第一换热器13内的冷媒进行热交换。第二机箱2内同样设置有第二风机、进风口和出风口。该第二风机在运行时通过进风口吸入室内空气，然后在通过出风口排出至室内。空气在第二机箱2内流经第二换热器22，从而与第二换热器22内的冷媒进行热交换。
或者参照图4，图4为本申请实施例方案涉及的空调器的系统结构图。空调器具有蓄能功能和放能功能。压缩机14、第一换热器13、水箱换热器16和膨胀阀18形成蓄能回路。在蓄能功能下，空调器通过蓄能回路向水箱15内存储冷量或热量。水箱15内存储有水，通过提高水的温度达到存储热量的目的，通过降低水的温度达到存储冷量的目的。在蓄冷时，压缩机14启动，将气态冷媒传输至第一换热器13进行冷凝，然后经过膨胀阀18后进入水箱换热器16进行蒸发，从而降低水的温度。在蓄热时压缩机14启动，将气态冷媒传输至水箱换热器16进行冷凝，然后经过膨胀阀18后进入第一换热器13进行蒸发，从而降低提高的温度。水箱15内还可以设置一个或者多个温度传感器17，以监测水箱15内的水温。
流量调节泵21、储能单元和第二换热器22形成放能回路。储能单元可以为水箱15，水箱15上设有出水口23和入水口24，流量调节泵21可以为水泵。在放能功能下，空调器通过放能回路利用水箱15内的冷量或热量进行制冷或制热。流量调节泵启动后，从水箱15中抽水，并将水送至第二换热器22。在水箱15中水为冷水时，第二换热器22能够降到流经的室内空气的温度，从而到达制冷的效果。在水箱15中水为热水时，第二换热器22能够提高流经的室内空气的温度，从而到达制热的效果。
空调器还包括控制器，该控制器与压缩机14、流量调节泵21和风机连接，用于控制各部件的运行。控制器8可以包括处理器和存储器等。存储器内存储有空调器的控制程序，处理器通过调用该空调器的控制程序，以执行本申请实施例提供的空调器的控制方法。
本领域技术人员可以理解，图1和图2中示出的结构并不构成对空调器的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
基于上述硬件结构，提出本申请空调器的控制方法的实施例。
参照图4，图4为本申请空调器的控制方法第一实施例的流程示意图，提出本申请空调器的控制方法第一实施例。
在第一实施例中，所述空调器的控制方法包括以下步骤：
步骤S10：在空调器制冷或者制热时，获取当前环境温度。
应理解的是，本实施例的执行主体是可以为前述空调器中的控制器，该控制器具有数据处理、数据通信及程序运行等功能。当然，还可为其他具有相似功能的设备，本实施条件对此不加以限制。
空调器可以设置有温度传感器，该温度传感器可以设置在第一机箱上（如进风管入口），以检测室外环境的温度，从而确定当前环境温度。或者该温度传感器可以设置在第二机箱上，以检测室内环境的温度，从而确定当前环境温度；当然，当前环境温度还可以采用其他方式获取，例如通过网络从气象数据库中获取，本实施方式对此不加以限制。
温度传感器可以按照设定的时间间隔向控制器反馈数据，降低温度传感器的功耗。其中，该时间间隔可以1分钟或者2分钟等，其具体值可以根据需求进行设置，本实施方式对此不加以限制。控制器在每次接收到温度传感器的反馈数据，根据接收到的当前环境温度执行本实施方式所涉及的控制流程。
空调器通常具有制热模式和制冷模式，为更准确的控制空调器的运行，还可以在空调器启动后，获取水箱内的水温；在接收到制冷指令，且水温小于第三温度时，控制空调器进入制冷模式；在接收到制热指令，且水温大于第四温度时，控制空调器进入制热模式。
水箱内同样可以设置有温度传感器，控制器通过接收设置在水箱内的温度传感器或者水箱内的水温。在水箱体积较大时，还可以采用多个温度传感器检测水温，从而提高水温的检测精度。
在进行制冷时，通常需要水箱内存储有足够的冷量；而在制热时，通常需要水箱内存储足够的热量。水箱内的水温可以反映冷量或者热量的存储量，冷量越多，水温越低；热量越多，水温越高。第三温度可以小于零度，如-2℃或者-3℃。在水温小于第三温度时，说明水箱内的冷量足够，此时若接收到制冷指令，则可以开始制冷。第四温度通常较高，如60℃或者65℃。在水温大于第三温度时，说明水箱内的热量足够，此时若接收到制热指令，则可以开始制热。用户还可以通过遥控器或者移动终端等设置的功能按钮等输入制冷指令或者制热指令。
步骤S20：根据当前环境温度控制蓄能功能和放能功能的开关。
本申请实施例中，空调器的蓄能功能和放能功能可以分别单独运行，也可以同时运行。例如，空调器启动后，线启动蓄能功能，压缩机启动，向水箱蓄冷或者蓄热；此时仅有蓄能功能运行。在蓄冷或者蓄热达到一定程度后，开启流量调节泵，利用水箱内水进行放冷或者放冷；此时压缩机可以保持启动状态，即蓄能功能和放能功能同时运行。在水箱内蓄冷或者蓄热达到设定上限时，可以关闭压缩机，而保持流量调节泵启动，此时仅有放能功能运行。参照前述的空调器结构，蓄能回路和放能回路属于两个不同的回路，其分别由不同的部件进行驱动。因此蓄能回路和放能回路在工作时，不会产生直接的相互影响。
需要说明的是，空调器在制冷时，若当前环境温度越高，则蓄冷和放冷时的系统压力越大；空调器在制热时，若当前环境温度越低，则蓄热和放热时的系统压力越大。若空调器的系统压力过大，则可能导致空调器停机，影响用户体验。
为避免系统压力过大，需要分别对蓄能功能和放能功能进行开关控制。其中，蓄能功能的开关控制主要通过控制压缩机的运行状态实现。在需要开启蓄能功能时，可以控制压缩机处于开机状态；在需要关闭蓄能功能时，可以控制压缩机处于停机状态。放能功能的开关控制主要通过控制流量调节泵的运行状态实现。在需要开启放能功能时，可以控制流量调节泵处于开机状态；在需要关闭放能功能时，可以控制流量调节泵处于停机状态。
为保证用户体验，在用户需要制冷或者制热时，需要优先保证放冷功能或者放热功能的开启。此时，为避免系统压力过高，可以选择性地开启或者关闭蓄能功能。即在制冷时，若当前环境温度较高，则可以关闭蓄冷功能，保持放冷功能开启；在制热时，若当前环境温度较第，则可以关闭蓄热功能，保持放热功能开启。在用户关闭制冷或者制热时，则关闭蓄能功能和放能功能。
在本实施方式中，通过在空调器制冷或者制热时，获取当前环境温度；然后根据当前环境温度控制蓄能功能和放能功能的开关；从而根据空调器系统压力分别对蓄能功能和放能功能进行开关控制，避免空调器系统压力过高导致停机，保证了空调器正常实现制冷或者制热。
参照图5，图5为本申请空调器的控制方法第二实施例的流程示意图。基于上述第一实施例，提出本申请空调器的控制方法第二实施例。
在本实施例中，为更有效地对空调器系统压力进行调节，步骤S20可以包括：
步骤S201：确定空调器的当前模式。
空调器的工作模式通常包括制冷模式和制热模式，用户通常会在室温较高的时候开启制冷模式，在室温较低的时候开启制热模式。在制冷模式下，室温越高，空调器系统压力越高，反之越低；在制热模式下，室温越高，空调器系统压力越低，反之越高。因此，在不同模式下，当前环境温度所反映系统压力也不同。
空调器的工作模式通常由用户控制，因此可以根据用户所输入的控制指令确定空调器的当前模式。若用户输入的控制指令为制冷指令，则当前模式为制冷模式；若用户输入的控制指令为制热指令，则当前模式为制热模式。当前，控制器还可以通过空调器的运行参数驱动当前模式。
步骤S202：根据当前模式和当前环境温度确定空调器的放能量。
需要说明的是，放能量可以空调器所需要提供的制冷量或者制热量的多少。因此，若控制器制冷，当前环境温度越高，则所需要的制冷量越多，放能量越大，反之则放能量越小；若控制器制热，当前环境温度越低，则所需要的制热量越多，放能量越大，反之则放能量越小。
在本实施方式中，可以将放能量设置为依次增大的第一阶梯、第二阶梯和第三阶梯。具体的，可以根据当前模式确定对应的参考温度，参考温度包括第一温度和第二温度；将当前环境温度分别与第一温度和第二温度进行比对，获得比对结果；根据比对结果确定空调器的放能量。
通过设置第一温度和第二温度划分了三个温度区间，每个温度区间对应一个放能量。正如前述，空调器在不同工作模式下，当前环境温度所反映系统压力也不同，故第一温度和第二温度在不同工作模式下也不相同。
例如，在空调器处于制冷模式下，第一温度可以为35℃，第二温度为43℃。若当前环境温度小于或等于35℃，则放能量为第一阶梯；若当前环境温度大于35℃，且小于或等于43℃，则放能量为第二阶梯；若当前环境温度大于35℃，则放能量为第三阶梯。在空调器处于制热模式下，第一温度可以为5℃，第二温度为12℃。若当前环境温度小于5℃，则放能量为第三阶梯；若当前环境温度大于或等于5℃，且小于12℃，则放能量为第二阶梯；若当前环境温度大于或等于12℃，则放能量为第一阶梯。当然，上述数值仅为示例，第一温度和第二温度的具体值可以根据需求进行设置，本实施方式对此不加以限制。
步骤S203：根据放能量控制蓄能功能和放能功能的开关。
为保证用户的制冷或者制热需求，需要保持放能功能处于开启状态；然后在根据放能功能所带的压力控制蓄能功能的开关。在放能量较大，则放能功能所带的系统压力（蓄能回路的压力）较大，此时可以控制蓄能功能关闭；在放能量较大，则放能功能所带的压力较小，此时可以控制蓄能功能开启。
以放能量包括第一阶梯、第二阶梯和第三阶梯为例，在放能量处于第一阶梯时，控制放能功能开启，并根据用户需求控制蓄能功能开启或关闭；在放能量处于第二阶梯时，控制放能功能和蓄能功能均开启；在放能量处于第三阶梯时，控制放能功能开启，并控制蓄能功能关闭。
在放能量处于第一阶梯时，说明放能回路所带来的系统压力不大，空调器系统压力较低。因此，可以保持放能功能开启。同样由于放能量较低，对水箱内存储的冷量或者热量消耗程度也不高，因此，也可以直接关闭蓄能功能。或者为保持放能功能的长久运行，也可以开启蓄能功能。其中，在开启蓄能功能时，可以控制压缩机以参考频率运行，参考频率随当前环境温度变化而变化。在制冷模式下，参考频率与当前环境温度呈正相关，即在当前环境温度小于或等于35℃的前提下，当前环境温度越高，参考频率越高，以保证放冷满足用户需求。在制热模式下，参考频率与当前环境温度呈负相关，即在当前环境温度的大于12℃的前提下，当前环境温度越低，参考频率越高，以保证放热满足用户需求。
在放能量处于第二阶梯时，空调器的负荷较大，放冷或者放热的峰值能力高，单独放能可能无法维持用户需求。此时由于系统压力还在可控范围内，可以控制蓄能功能和放能功能同时开启。另外，为避免引起系统过载，可以控制压缩机以设定频率范围内的频率运行，从而限制蓄能功能所带来的压力，避免空调器系统过压。其中，该设定频率范围可以根据需求进行设置，本实施方式对此不加以限制。
在放能量处于第三阶梯时，系统压力超标，为保证系统的可靠性，同时满足用户的需求，需要关闭蓄能功能，仅保持放能功能运行。通常，在环境温度较高时，随着水箱蒸发压力的提高，系统的压力则可能超标。
在本实施方式中，通过确定空调器的当前模式；然后根据当前模式和当前环境温度确定放能量；再根据放能量控制蓄能功能和放能功能的开关。本实施方式通过利用当前环境温度对空调器的放能量进行区分，从而在不同阶梯的放能量下分别控制蓄能功能和放能功能的开关，从而在保证用户需求的前提下，对空调器系统压力进行限制，避免过压引起停机。
此外，本申请实施例还提出一种存储介质，所述存储介质上存储有空调器的控制程序，所述空调器的控制程序被处理器执行时实现如上文所述的空调器的控制方法的步骤。由于本存储介质可以采用上述所有实施例的技术方案，因此至少具有上述实施例的技术方案所带来的有益效果，在此不再一一赘述。
此外，参照图6，图6为本申请空调器的控制装置第一实施例的结构框图。本申请实施例还提出一种空调器的控制装置。
在本实施方式中，空调器的控制装置包括：
检测模块10，用于在空调器制冷或者制热时，获取当前环境温度。
空调器可以设置有温度传感器，该温度传感器可以设置在第一机箱上（如进风管入口），以检测室外环境的温度，从而确定当前环境温度。或者该温度传感器可以设置在第二机箱上，以检测室内环境的温度，从而确定当前环境温度；当然，当前环境温度还可以采用其他方式获取，例如通过网络从气象数据库中获取，本实施方式对此不加以限制。
温度传感器可以按照设定的时间间隔向控制器反馈数据，降低温度传感器的功耗。其中，该时间间隔可以1分钟或者2分钟等，其具体值可以根据需求进行设置，本实施方式对此不加以限制。检测模块10在每次接收到温度传感器的反馈数据，根据接收到的当前环境温度执行本实施方式所涉及的控制流程。
空调器通常具有制热模式和制冷模式，为更准确的控制空调器的运行，还可以在空调器启动后，获取水箱内的水温；在接收到制冷指令，且水温小于第三温度时，控制空调器进入制冷模式；在接收到制热指令，且水温大于第四温度时，控制空调器进入制热模式。
水箱内同样可以设置有温度传感器，检测模块10通过接收设置在水箱内的温度传感器或者水箱内的水温。在水箱体积较大时，还可以采用多个温度传感器检测水温，从而提高水温的检测精度。
在进行制冷时，通常需要水箱内存储有足够的冷量；而在制热时，通常需要水箱内存储足够的热量。水箱内的水温可以反映冷量或者热量的存储量，冷量越多，水温越低；热量越多，水温越高。第三温度可以小于零度，如-2℃或者-3℃。在水温小于第三温度时，说明水箱内的冷量足够，此时若接收到制冷指令，则可以开始制冷。第四温度通常较高，如60℃或者65℃。在水温大于第三温度时，说明水箱内的热量足够，此时若接收到制热指令，则可以开始制热。用户还可以通过遥控器或者移动终端等设置的功能按钮等输入制冷指令或者制热指令。
控制模块20，用于根据当前环境温度控制蓄能功能和放能功能的开关。
参照前述的空调器结构，蓄能回路和放能回路属于两个不同的回路，其分别由不同的部件进行驱动。因此蓄能回路和放能回路在工作时，不会产生直接的相互影响。
需要说明的是，空调器在制冷时，若当前环境温度越高，则蓄冷和放冷时的系统压力越大；空调器在制热时，若当前环境温度越低，则蓄热和放热时的系统压力越大。若空调器的系统压力过大，则可能导致空调器停机，影响用户体验。
为避免系统压力过大，需要分别对蓄能功能和放能功能进行开关控制。其中，蓄能功能的开关控制主要通过控制压缩机的运行状态实现。在需要开启蓄能功能时，可以控制压缩机处于开机状态；在需要关闭蓄能功能时，可以控制压缩机处于停机状态。放能功能的开关控制主要通过控制流量调节泵的运行状态实现。在需要开启放能功能时，可以控制流量调节泵处于开机状态；在需要关闭放能功能时，可以控制流量调节泵处于停机状态。
为保证用户体验，在用户需要制冷或者制热时，需要优先保证放冷功能或者放热功能的开启。此时，为避免系统压力过高，可以选择性地开启或者关闭蓄能功能。即在制冷时，若当前环境温度较高，则可以关闭蓄冷功能，保持放冷功能开启；在制热时，若当前环境温度较第，则可以关闭蓄热功能，保持放热功能开启。在用户关闭制冷或者制热时，则关闭蓄能功能和放能功能。
在本实施方式中，检测模块10在空调器制冷或者制热时，获取当前环境温度；控制模块20根据当前环境温度控制蓄能功能和放能功能的开关；从而根据空调器系统压力分别对蓄能功能和放能功能进行开关控制，避免空调器系统压力过高导致停机，保证了空调器正常实现制冷或者制热。
在一实施例中，控制模块20还用于确定空调器的当前模式，当前模式为制冷模式或制热模式；根据当前模式和当前环境温度确定放能量；根据放能量控制蓄能功能和放能功能的开关。
在一实施例中，放能量包括依次增大的第一阶梯、第二阶梯和第三阶梯，控制模块20还用于在放能量处于第一阶梯时，控制放能功能开启，并根据用户需求控制蓄能功能开启或关闭；在放能量处于第二阶梯时，控制放能功能和蓄能功能均开启；在放能量处于第三阶梯时，控制放能功能开启，并控制蓄能功能关闭。
在一实施例中，控制模块20还用于根据当前模式确定对应的参考温度，参考温度包括第一温度和第二温度；将当前环境温度分别与第一温度和第二温度进行比对，获得比对结果；根据比对结果确定空调器的放能量。
在一实施例中，控制模块20还用于在放能量处于第一阶梯，且蓄能功能开启时，控制压缩机以参考频率运行，参考频率随当前环境温度变化而变化。
在一实施例中，控制模块20还用于在放能量处于第二阶梯时，控制压缩机以设定频率范围内的频率运行。
本申请所述空调器的控制装置的其他实施例或具体实现条件可参照上述各方法实施例，因此至少具有上述实施例的技术方案所带来的所有有益效果，此处不再赘述。
以上仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
