术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在多联机系统中一台室外机通常连接两台或者两台以上的室内机，例如图1所示的多联机系统，包括1台室外机和6台室内机。其中，在一室内机需要运行制热模式(例如，用户通过遥控器、线控器或室内机外壳上的操控板开启室内机的制热模式)的情况下，该室内机称为制热内机；类似的，在一室内机需要运行除湿模式的情况下， 该室内机称为除湿内机。当多联机系统中同时包括至少一台(一台或多台)除湿内机和至少一台(一台或多台)制热内机时，制冷剂(也称冷媒)会在除湿内机的蒸发器和制热内机的冷凝器中循环，在各台除湿内机的蒸发器的容积和与各台制热内机的冷凝器的容积和匹配时，则认为当前的制热内机能够支持当前的除湿内机同时运行除湿状态，且各除湿内机均有良好的除湿性能。当各台除湿内机的蒸发器的容积和与各台制热内机的冷凝器的容积和不匹配时(不匹配的情况常发生于除湿内机的台数多于制热内机的台数时)；例如图1所示，若室内机A、C开启制热模式的同时，室内机B、D、E、F开启除湿模式，即除湿内机有4台，而制热内机只有2台，且当除湿内机的蒸发器的容积和大于多台制热内机的冷凝器的容积和时，相关技术中各台除湿内机需同时运行除湿状态，这样会使得除湿内机的除湿性能较差，甚至出现部分除湿内机无法除湿的问题。
在多联机系统中，除湿内机的台数多于制热内机的台数的一个场景是：当用户房间个数较多时，有些房间作为地下室，在过渡季节或冬季等时节，当地下室的湿度较大时，容易发霉，所以需要除湿。因此可能一部分房间需要制热，另一部分房间需要除湿。当多联机系统中制热内机的冷凝器与除湿内机的蒸发器的容积(即换热器内用于容纳冷媒的体积)不匹配，例如除湿需求较大，使得除湿内机的台数多于制热内机的台数时，可能导致除湿内机的除湿性能不佳的问题。
本公开一些实施例提出一种多联机系统的分时除湿方法，通过控制多台除湿内机在不同的时段运行除湿状态，例如在一次分时除湿过程中的一控制周期内，控制除湿内机B、D运行除湿状态，在另一控制周期内，控制除湿内机E、F运行除湿状态，以保证在一次分时除湿过程中的一控制周期内，运行除湿状态的除湿内机的蒸发器的容积和与运行制热状态的制热内机的冷凝器的容积和匹配(例如，蒸发器的容积和小于或等于冷凝器的容积和)，使得运行除湿状态的除湿内机的除湿性能良好。
以下对本公开一些实施例提供的多联机系统的分时除湿方法进行 详细的说明。以下实施例以图1所示的多联机系统中，室内机A、C为制热内机，室内机B、D、E、F为除湿内机为例进行说明。
本公开一些实施例提供一种多联机系统的分时除湿方法，如图2所示包括：
步骤101：在一次分时除湿过程中的一控制周期，针对第一集合内的在本次分时除湿过程中未进行过除湿的除湿内机，设置一个第一除湿内机的运行状态为进行除湿状态，并确定除第一除湿内机以外多联机系统中当前的制热内机还能够支持的最大数量的第二除湿内机，若存在第二除湿内机，则设置各第二除湿内机的运行状态为进行除湿状态，其中，第一集合由多联机系统中当前的除湿内机组成。
在一些实施例中，响应与室内机中同时存在除湿内机和制热内机时，启动分时除湿。在一些实施例中，响应与室内机中同时存在除湿内机和制热内机时且制热内机的容积小于除湿内机的容积时，启动分时除湿。
需要说明的是，当前的除湿内机是指多联机系统中当前需要运行除湿状态的室内机，例如本公开的一些实施例中，上述室内机B、D、E、F为当前的除湿内机，则这4台除湿内机构成第一集合。同理，上述室内机A、C为当前的制热内机。一次分时除湿过程是指上述室内机B、D、E、F均运行一次除湿状态的过程，在此过程中可以包含一个或多个控制周期，任一个控制周期内均可以按照本实施例提供的方法完成。示例的，一控制周期的时长可以是预先设定的常数，也可以是依据设定的规则而确定的时间段。
以上述室内机均为三管制的室内机为例，运行除湿状态时，该室内机的一个室内换热器作为蒸发器，另一个室内换热器不工作；运行制热状态时，该室内机的一个室内换热器作为冷凝器，另一个室内换热器不工作。当然，上述室内机也可以为其他管制，例如室内机为两管制的室内机时，运行制热状态时，该室内机的室内换热器作为冷凝器。需要说明的是，本公开实施例所述的三管制的室内机可以如图7所示包括第一室内换热器11和第二室内换热器12、以及分别与各室内 换热器相连接的第一室内电子膨胀阀13和第二室内电子膨胀阀14。
选择一个除湿内机作为第一除湿内机的方法有多种。
在一些实施例中，在一次分时除湿过程中的一个控制周期中，对于图1所示的多联机系统中，可以以本次分时除湿过程中未进行过除湿的除湿内机中任选一个作为第一除湿内机。例如，在一次分时除湿过程中的第一个控制周期，室内机B、D、E、F均未进行过除湿，则可以以室内机B、D、E、F中的任意一个，例如室内机B作为第一除湿内机。
在一些实施例中，在一个控制周期中还可以从本次分时除湿过程中未进行过除湿的除湿内机中按照预设规则确定一个除湿内机作为第一除湿内机。例如，按照各个除湿内机的排序，从本次分时除湿过程未进行过除湿的除湿内机中确定第一除湿内机。
在一次分时除湿过程中，本公开一些实施例提供的分时除湿方法还可以包括如图3所示的步骤201：对第一集合内的除湿内机进行编号，其中编号的方式可以是按照等差数列的规则，也可以按照其他排序规则。示例的，可以从0开始，以公差为1将上述除湿内机B、D、E、F分别编号为0、1、2、3。并从本次分时除湿过程未进行过除湿的除湿内机中，确定编号最小的除湿内机为第一除湿内机。
需要说明的是，对第一集合内的除湿内机进行编号时，也可以采用其他规则，例如按照26个字母的排列顺序，用字母对第一集合内的除湿内机进行编号，或者按照等比数列的规则对第一集合内的除湿内机进行编号，本公开的实施例对此不限定。考虑到按照等差数列的规则进行编号时，分时除湿方法的算法较为简单，因此在一些实施例中，按照等差数列的规则，对第一集合内的除湿内机进行编号。
在一些实施例中，可以在每次分时除湿过程中进行一次步骤201；也可以在多联机系统从开启到关闭过程中，除湿内机的分布每改变一次时进行一次步骤201，例如增加或减少除湿内机的数量，或者除湿内机的数量不变、但除湿内机的分布改变(例如除湿内机由室内机B、D、E、F，改变为室内机B、C、E、F)。并且，若多联机系统从开启到 关闭除湿内机的分布并未改变，则室内机B、D、E、F分时除湿的过程可以进行一次，也可以循环多次。
在此基础上，在一些实施例中，上述步骤101中，针对第一集合内的在本次分时除湿过程中未进行过除湿的除湿内机，设置一个第一除湿内机的运行状态为进行除湿状态，包括：
在一控制周期，针对第一集合内的在本次分时除湿过程中未进行过除湿的除湿内机，以编号最小的除湿内机作为第一除湿内机，例如结合上述，在一次分时除湿过程中的第一个控制周期，将编号为0的室内机B作为第一除湿内机，设置第一除湿内机的运行状态为进行除湿状态。
当然，也可以将编号最大的除湿内机作为第一除湿内机，本公开的一些实施例以将编号最小的除湿内机作为第一除湿内机为例进行说明。
在确定第一除湿内机后，在步骤101中，还需要确定除第一除湿内机以外多联机系统中当前的制热内机A、C还能够支持的最大数量的第二除湿内机。各第二除湿内机与第一除湿内机的编号连续，即第一除湿内机与各第二除湿内机的编号按照从小到大的顺序连续排列。
需要说明的是，各第二除湿内机与第一除湿内机的编号连续是指：各个第二除湿内机的编号连续，且在一控制周期内，各第二除湿内机与第一除湿内机的编号连续。例如，当确定编号m(例如m为0)的除湿内机为第一除湿内机后，从第一除湿内机的下一台除湿内机，即编号为m+1(例如m+1为1)的除湿内机开始确定第二除湿内机。假设在一控制周期内，当前的制热内机A、C能够支持除上述第一除湿内机(即室内机B)外还可以支持室内机D运行除湿状态，则编号为1的室内机(即室内机D)作为第二除湿内机。
在此基础上，如图2所示，本公开一些实施例提供的多联机系统的分时除湿方法还包括步骤102：设置第一集合中剩余除湿内机的运行状态为暂不除湿状态，剩余除湿内机为在该控制周期内未被设置为进行除湿状态的除湿内机。
需要说明的是，与进行除湿状态相对的是暂不除湿状态；暂不除湿状态是指，当前的除湿内机在本控制周期内不进行除湿的状态，在一控制周期内，除第一除湿内机和各第二除湿内机的运行状态为进行除湿状态外，其他的除湿内机(剩余除湿内机)的运行状态为暂不除湿状态。剩余除湿内机为一控制周期中除第一除湿内机和第二除湿内机以外的除湿内机。
结合上述，如图4所示,假设第一个控制周期中，被设置为运行除湿状态的除湿内机的编号为0和1(即除湿内机B和D)，则第一个控制周期中的剩余除湿内机的编号为2和3，即除湿内机E和F为剩余除湿内机。假设第二个控制周期中如图5所示，被设置为运行除湿状态的除湿内机的编号为2(即除湿内机E)，则在第二个控制周期中的剩余除湿内机包括编号为0、1和3的除湿内机，即包括第一个控制周期中被设置为运行除湿状态的除湿内机(编号0和1)以及在本次分时除湿过程中未进行过除湿的除湿内机(编号3)。
需要说明的是，图4、图5和图6中，阴影实线框表示在一控制周期内该除湿内机运行除湿状态，阴影虚线框表示在一次分时除湿过程中的之前的控制周期内该除湿内机运行过除湿状态在本周期中处于暂不除湿状态，无阴影虚线框表示在在一控制周期内该除湿内机处于暂不除湿状态。
基于此，以图4所示的多联机系统的一次分时除湿过程包括三个控制周期为例，参照图4、图5和图6，简要说明根据本公开一些实施例提供的多联机系统的分时除湿方法。当前的除湿内机包括室内机B、D、E、F，在一次分时除湿过程中的第一个控制周期，可以将当前的除湿内机的任意一个，例如室内机B作为第一除湿内机，并将该第一除湿内机的运行状态设置为进行除湿状态；假设除第一除湿内机以外多联机系统中当前的制热内机还能够支持室内机D，则以室内机D作为第二除湿内机，并设置室内机D的运行状态为进行除湿状态；将在该控制周期内未被设置为除湿状态的除湿内机，即室内机E和F的运行状态均设置为暂不除湿状态。则第一个控制周期中，设置室内机B 和D的运行状态为进行除湿状态。在该第一个控制周期结束后，进入本次分时除湿过程的第二个控制周期。
在一次分时除湿过程中的第二个控制周期，如图5所示，以本次分时除湿过程中未进行过除湿的除湿内机，即室内机E和F中的任意一个，例如室内机E作为第一除湿内机，并将该第一除湿内机的运行状态设置为进行除湿状态；假设多联机系统中当前的制热内机仅能支持室内机E，即该第二个控制周期中不存在第二除湿内机，则将在该控制周期内未被设置为除湿状态的除湿内机，即室内机B、D和室内机F的运行状态设置为暂不除湿状态。则第二个控制周期中，设置室内机E的运行状态为进行除湿状态。在该第二个控制周期结束后，进入本次分时除湿过程的第三个控制周期。
在一次分时除湿过程中的第三个控制周期，如图6所示，将本次分时除湿过程中未进行过除湿的除湿内机，即室内机F作为第一除湿内机，并将该第一除湿内机的运行状态设置为进行除湿状态；由于室内机F为本次分时除湿过程中最后一台未进行过除湿的除湿内机，则该控制周期中不存在第二除湿内机；并将在该控制周期内未被设置为除湿状态的除湿内机，即室内机B、D、E的运行状态均设置为暂不除湿状态。则第三个控制周期中，仅设置室内机F的运行状态为进行除湿状态。在该控制周期结束后，本次分时除湿过程可以结束；或者循环执行上述各个控制周期，本实施例对此不限定。
这样一来，根据本公开一些实施例提供的分时除湿方法，在一次分时除湿过程中，既可以保证所有当前除湿内机均可以运行一次除湿状态，也能使得在一次分时除湿过程的各个控制周期内，各运行除湿状态的除湿内机的除湿性能良好。从而避免了在当前的制热内机和当前的除湿内机容积不匹配的情况下，当前的所有除湿内机同时运行除湿状态导致的除湿内机的除湿性能较差、甚至部分除湿内机无法除湿的问题。
在此基础上，基于对第一集合内的除湿内机以等差数列进行编号的方案，在一些实施例中，结合图3对一次分时除湿方法中的一个控 制周期进行详细介绍，在步骤201之后，包括以下步骤：
步骤202：在一次控制周期，以编号为m的除湿内机作为第一除湿内机。
需要说明的是，以在步骤201中，将图4所示的多联机系统中当前除湿内机分别编号为0、1、2和3为例进行说明。
结合上述示例，在一次分时除湿过程的第一个控制周期中，第一除湿内机为编号为0(即室内机B，此时m＝0)的除湿内机。在后续控制周期(非第一个控制周期)，第一除湿内机为在本次分时除湿过程中未进行过除湿的除湿内机的编号中最小的编号所对应的除湿内机。
步骤203：设置编号m的除湿内机的运行状态为进行除湿状态。即设置第一除湿内机的运行状态为进行除湿状态。
示例的，可以将编号m的除湿内机的状态标识位(用于表示运行状态的标识位)设置成第一标识(例如0)，第一标识用于表示进行除湿状态，并控制编号为m的除湿内机的运行状态为运行除湿状态。
需要说明的是，此步骤的顺序在步骤202之后即可，例如，可以与步骤212同时执行。
步骤204：设置编号为小于或等于m-1(可以表示为≤m-1，或者表示为0～(m-1))的除湿内机的运行状态为暂不除湿状态。
示例的，可以将编号0～(m-1)的除湿内机的状态标识位设置成第二标识(例如1)，第二标识用于表示暂不除湿状态，此时这些除湿内机的运行状态为暂不运行除湿状态。
需要说明的是，在一次分时除湿过程的第一个控制周期，m＝0,不存在编号小于或等于m-1的除湿内机；在非第一个控制周期，结合上述示例，在第二个控制周期，m＝2，则设置编号为0和1的除湿内机，即在第一个控制周期中所有运行除湿状态的除湿内机的运行状态为暂不除湿状态。此步骤的顺序在步骤202之后即可，例如，可以与步骤213同时执行。
步骤205：令j＝m。
步骤206：判断j是否小于N_total-1。其中，N_total用于表示当 前的除湿内机的个数，即第一集合中除湿内机的个数。步骤206是为了判断被累加的除湿内机是否包括本次分时除湿过程中的最后一台未进行过除湿的除湿内机。
结合上述示例，N_total＝4；在一次分时除湿过程的第三个控制周期内，m＝3，即第一除湿内机的编号为3。执行步骤206时，j＝N_total-1，即编号3的除湿内机为本次分时除湿过程中的最后一台未进行过除湿的除湿内机，因此无需进行确定第二除湿内机的相关步骤，在该控制周期内，仅编号3的除湿内机运行除湿状态。
若j小于N_total-1，则执行步骤207；若j等于N_total-1，则执行步骤214。
步骤207：j＝j+1。
需要说明的是，步骤207是为了确定出除第一除湿内机外的下一台除湿内机。当按照等差数列的规则对除湿内机编号后，在步骤207中执行j＝j+x，其中，x表示等差数列的公差，本公开一些实施例的步骤206中以公差为1为例进行示意。当按照其他规则对除湿内机编号后，根据实际编号规则确定除第一除湿内机外的下一台除湿内机，本公开实施例对此不再赘述。
步骤208：将第一除湿内机的蒸发器的容积与第一集合内的在本次分时除湿过程中未进行过除湿的除湿内机的蒸发器的容积逐一累加，判断累加结果是否满足
Figure PCTCN2019078914-appb-000001
其中，
Figure PCTCN2019078914-appb-000002
表示从第一除湿内机开始，累加的第一集合内的在本次分时除湿过程中未进行过除湿的除湿内机的容积和；∑Heat_HP用于表示多联机系统中当前的制热内机的容积和；K DH_CAP用于表示控制系数。其中，该控制系数K DH_CAP为制热内机的容积和与能够支持的除湿内机的容积和的比值。该控制系数K DH_CAP可以根据实际需求进行设定。在一些实施例中，控制系数K DH_CAP的范围是1.3～3.0；在一些实施例中，控制系数K DH_CAP为1.5。
参照图3并结合上述示例，假设在一次分时除湿过程的第一个控制周期，累加编号为0和1的除湿内机的容积，累加结果不满足
Figure PCTCN2019078914-appb-000003
则执行步骤209，由于编号1的除湿内机不是本次分时除湿过程中的最后一台未进行过除湿的除湿内机，则执行步骤207和208；再累加编号为2的除湿内机的容积时，累加结果满足
Figure PCTCN2019078914-appb-000004
则执行步骤210，即n＝j＝2，此时除编号为0的除湿内机以外，当前的制热内机还能够支持的最大数量的第二除湿内机的编号为1。
需要说明的是，在上述步骤208中，也可以判断累加结果是否满足
Figure PCTCN2019078914-appb-000005
结合上述示例，在第一个控制周期，累加编号为0、1和2的除湿内机的容积时，累加结果满足
Figure PCTCN2019078914-appb-000006
则执行步骤209，由于编号2的除湿内机不是本次分时除湿过程中的最后一台未进行过除湿的除湿内机，则执行步骤207和步骤208；继续累加编号为3的除湿内机的容积，累加结果满足
Figure PCTCN2019078914-appb-000007
则执行步骤210，即n＝j＝3。结合上述，理论上应以编号为1和2的除湿内机作为第二除湿内机，即在一控制周期内，同时设置编号为0、1和2的除湿内机运行除湿状态，此时在除湿内机在当前的除湿内机能够支持的临界数量下运行除湿状态，此时可能会使得除湿内机的除湿性能不佳。因此在一些实施例中，当累加结果满足
Figure PCTCN2019078914-appb-000008
时，将最后一台被累加的除湿内机不作为第二除湿内机，即步骤208中，判断累加结果是否满足
Figure PCTCN2019078914-appb-000009
步骤209：判断j是否等于N_total-1。
判断在累加结果不满足
Figure PCTCN2019078914-appb-000010
时，是否累加到本次分时除湿过程中的最后一台未进行过除湿的除湿内机，若累加到本次分时除湿过程中的最后一台未进行过除湿的除湿内机，则执行步骤210，即停止累加，并以除第一除湿内机以外被累加的除湿内机作为第二除湿内机。若没有累加到本次分时除湿过程中的最后一台未进行过除湿的除湿内机，则执行步骤207。
步骤210：令n＝j。
步骤211：判断m、n是否满足(m+1)≤(n-1)。
当m、n不满足(m+1)≤(n-1)，则执行步骤213；当m、n满足(m+1)≤(n-1)，此时第二除湿内机的编号范围是(m+1)～(n-1)，执行步骤212。
结合上述示例，在一次分时除湿过程的第一个控制周期，m＝0，j＝2，则步骤210中，n＝j＝2，则m、n满足(m+1)≤(n-1)，则该控制周期中，当前的制热内机能够支持编号为0和1的除湿内机运行除湿状态，此时第二除湿内机的编号为1。
在一次分时除湿过程的第二个控制周期，m＝2，j＝3，则步骤210中，n＝j＝3，则m、n不满足(m+1)≤(n-1)，则该控制周期中，当前的制热内机仅能够支持编号为2的除湿内机运行除湿状态，则不存在第二除湿内机。
步骤212：设置编号(m+1)～(n-1)的除湿内机的运行状态为运行除湿状态。
结合上述示例，确定编号(m+1)～(n-1)的除湿内机为第二除湿内机，并设置第二除湿内机的运行状态为运行除湿状态。
这样一来，根据本公开一些实施例提供的分时除湿方法，可以确定出一控制周期内，当前的制热内机能够支持的最大数量的除湿内机，并将该部分除湿内机的运行状态设置为运行除湿状态。在此情况下，可以保证一控制周期内，各运行除湿状态的除湿内机的除湿性能良好。
步骤214：维持现有状态。
需要说明的是，在当前的制热内机和当前的除湿内机没有发生调整、以及控制周期未结束的情况下，多联机系统的各室内机的运行状态维持当前状态；各室内机的运行状态维持当前状态时，无需进行附加操作。
在此基础上，若该控制周期不是本次分时除湿过程中的最后一个控制周期，则在该控制周期结束后，进入本次分时除湿过程中的下一个控制周期。
在一些实施例中，该过程可以通过图3所示的步骤215实现，例如，判断该控制周期TDH是否结束。若该控制周期不是本次分时除湿 过程中的最后一个控制周期，该控制周期TDH结束后，进入本次分时除湿过程中的下一个控制周期，即重新执行图3所示的各个步骤。
需要说明的是，当该控制周期结束后，在本次分时除湿过程中第一集合的所有除湿内机均运行过除湿状态，则认为该控制周期为本次分时除湿过程中的最后一个控制周期。
综上所述，本公开一些实施例提供的基于对第一集合内的除湿内机以等差数列进行编号的分时除湿方法，在一次分时除湿过程中，既可以保证所有当前除湿内机均可以运行一次除湿状态，也能使得在一次分时除湿过程的各个控制周期内，各运行除湿状态的除湿内机的除湿性能良好。从而避免了在当前的制热内机和当前的除湿内积容积不匹配的情况下，当前的所有除湿内机同时运行除湿状态导致的除湿内机的除湿性能较差、甚至部分除湿内机无法除湿的问题。
在此基础上，若一控制周期是本次分时除湿过程中的最后一个控制周期，在该控制周期结束后，本次分时除湿过程结束。然而通常在实际应用中，需要多次分时除湿过程循环进行以使得各台当前除湿内机循环运行除湿状态，因此在一些实施例中，若一控制周期是本次分时除湿过程中的最后一个控制周期，在该控制周期结束后，进入下一次分时除湿过程中的第一个控制周期。
需要说明的是，在一次分时除湿过程结束后，将编号m重置为0，以使得在下一次分时除湿过程中的第一个控制周期，从编号为0的除湿内机开始依次运行除湿状态。
此外，当一次分时除湿过程中，多联机系统中第一集合中的除湿内机和/或当前的制热内机发生调整(也称运行室数发生变化)，例如当前的除湿内机或当前的制热内机的个数发生变化，或者多联机系统中作为除湿内机或制热内机的具体室内机发生变化，在一些实施例中，若将图4所示的多联机系统中，当前的除湿内机变化为室内机A、B、D，当前的制热内机变化为室内机E、F，此时当前的制热内机E、F能够支持的最大数量的除湿内机也会发生变化，在此情况下，若依然进行本次分时除湿过程，则无法使得各当前的除湿内机均运行一次除 湿状态。
在此基础上，在一些实施例中，本公开实施例提供的分时除湿方法还包括：本次分时除湿过程中若第一集合中的除湿内机发生调整，或者当前的制热内机发生调整，又或者第一集合中的除湿内机和当前的制热内机均发生调整，则进入下一次分时除湿过程。在此情况下，在新的分时除湿过程中的各控制周期，根据上述分时除湿方法重新确定第一除湿内机和第二除湿内机，以使得在一控制周期中，运行除湿状态的除湿内机的除湿性能良好。
在一些实施例中，上述步骤101中确定除第一除湿内机以外多联机系统中当前的制热内机还能够支持的最大数量的第二除湿内机的方法包括：
若第一除湿内机不是本次分时除湿过程中的最后一台未进行过除湿的除湿内机，将第一除湿内机的容积与第一集合内的在本次分时除湿过程中未进行过除湿的除湿内机的容积逐一累加，直至确定出累加结果小于或者等于参考阈值的当前的制热内机还能够支持的最大数量的第二除湿内机。
或者，累加到本次分时除湿过程中的最后一台未进行过除湿的除湿内机，累加结果仍小于参考阈值，则以除第一除湿内机以外被累加的除湿内机作为第二除湿内机；其中，参考阈值为多联机系统中当前的制热内机的容积和与控制系数K DH_CAP的比值。
需要说明的是，该过程可以通过如图3所示的步骤206-步骤209实现，其中，参考阈值为上述
Figure PCTCN2019078914-appb-000011
即为多联机系统中当前的制热内机的容积和与控制系数K DH_CAP的比值。由于前述实施例已经对上述步骤206-步骤209的具体过程进行了详细的说明，因此此处不再赘述。图3所示的分时除湿方法是通过编号的方式确定出第一除湿内机和第二除湿内机；当然，也可以不采用上述编号的方式确定第一除湿内机和第二除湿内机，在一些实施例中，在确定第一除湿内机后，可以采用指针的方式逐一累加第一除湿内机的容积和第一集合内的在本次分时除湿过程中未进行过除湿的除湿内机的容积，以确 定出上述第二除湿内机。在本公开实施例提供的分时除湿方法的总体思路下，本领域技术人员也可以采用其他方式，对确定第二除湿内机的具体方案进行调整，本公开实施例对此不进行限定。
此外，本领域普通技术人员可以理解：实现上述方法的全部或部分步骤可以通过程序指令相关的硬件来完成，前述的程序可以存储于一计算机可读取存储介质中，所述计算机程序被处理器执行时实现上述多联机系统的分时除湿方法。该程序在执行时，执行包括上述方法实施例的步骤；而前述的存储介质包括：ROM(英文全称：Read Only Memory image，中文名称：只读存储器镜像)、RAM(英文全称：Random Access Memory，中文名称：随机存取存储器)、磁碟或者光盘等各种可以存储程序代码的介质。
在此基础上，上述除湿内机包括未位于除湿回路上的第一室内电子膨胀阀、以及位于除湿回路上的第一室内电子膨胀阀。以图7所示的多联机系统为例，该多联机系统包括室外机01、室内机02和室内机03，其中室内机02为制热内机，室内机03为除湿内机，室内机03的第一室内换热器11和第一室内电子膨胀阀13未位于除湿回路上，第二室内换热器12和第二室内电子膨胀阀14位于除湿回路上。图7所示的多联机系统以包括一个除湿内机和一个制热内机进行示意，当包括多个制热内机02和多个除湿内机03时，各个室内机的结构可以与上述制热内机02和除湿内机03的结构相同。
在此基础上，设置除湿内机03的运行状态为进行除湿状态包括：
除湿内机03的第一室内电子膨胀阀13为关闭状态，以使得第一室内换热器11不工作；
除湿内机03的第二室内电子膨胀阀14的开度的初始值EVR(0)为一预设值；在一次分时除湿过程中的第n个控制周期，除湿内机02的第二室内电子膨胀阀14的开度EVR(n)满足：EVR(n)＝EVR(n-1)+5×(SH-SHo)；其中，SH用于表示除湿内机的气管16的温度与液管15的温度的差值，SHo用于表示目标蒸发过热度。从而除湿内机03的第二室内换热器12可以作为蒸发器以除湿。
需要说明的是，上述初始值EVR(0)可以根据实际需求设定，在一些实施例中，EVR(0)的取值范围是100puls～150puls。上述目标蒸发过热度SHo可以为一预设值，也可以根据除湿内机02的回风相对湿度、用户设定湿度、以及除湿内机的液管温度和回风温度进行确定。
在此基础上，在一些实施例中上述目标蒸发过热度SHo可以根据表1确定：
表1
ΔH SHo
ΔH≤-10％ (Ti-Tlp)+4
-10％<ΔH≤0 (Ti-Tlp)
0<ΔH≤10％ 3×(Ti-Tlp)+4
10％<ΔH≤20％ (Ti-Tlp)/2
20％<ΔH 3
其中，ΔH＝Hs-Hi；Hi用于表示除湿内机的回风相对湿度，Hs用于表示用户设定湿度，Ti用于表示除湿内机的回风温度，Tlp用于表示除湿内机02的液管15的温度。其中，回风相对湿度指的是除湿内机的回风处的相对湿度。
基于此，本公开实施例提供了一种一次分时除湿过程中的各个控制周期中，除湿内机中未位于除湿回路上的第一室内电子膨胀阀13和位于除湿回路上的第二室内电子膨胀阀14的开度控制方法，以保证各个控制周期中除湿内机的除湿性能良好。
在此基础上，设置除湿内机03的运行状态为暂不除湿状态包括：除湿内机03的第一室内电子膨胀阀13和第二室内电子膨胀阀14为全关状态。
此外，在上述一次分时除湿过程中，上述制热内机的运行状态为进行制热状态，在一些实施例中，如图7所示，制热内机的第二室内电子膨胀阀14’为全关状态，以使得第二室内换热器12’不工作；第一室内电子膨胀阀13’为全开状态，以使得第一室内换热器11’作为冷凝 器以制热。
根据本公开一些实施例提供的分时除湿方法，在一次分时除湿过程中的一控制周期，确定一个第一除湿内机和当前的制热内机还能够支持的最大数量的第二除湿内机，设置第一除湿内机的运行状态为运行除湿状态，若存在上述第二除湿内机，将第二除湿内机的运行状态设置为运行除湿状态；并将在该控制周期内未被设置为除湿状态的除湿内机设置为暂不除湿状态。若该控制周期不是本次分时除湿过程中的最后一个控制周期，则在该控制周期结束后，进入本次分时除湿过程中的下一个控制周期。这样一来，在一次分时除湿过程中，既可以保证所有当前除湿内机均可以运行一次除湿状态，也能保证在各个控制周期内，当前的制热内机能够支持第一除湿内机和第二除湿内机运行除湿状态，从而在各控制周期内，各运行除湿状态的除湿内机的除湿性能良好，从而避免了在当前的制热内机和当前的除湿内机容积不匹配的情况下，当前的所有除湿内机同时运行除湿状态导致的除湿内机的除湿性能较差、甚至部分除湿内机无法除湿的问题。
本公开一些实施例还提供一种多联机系统，包括存储器和处理器，所述存储器存储能够在所述处理器上运行的计算机程序，所述处理器配置为运行所述计算机程序以使所述多联机系统实现：在一次分时除湿过程中的一控制周期内，多个除湿内机中的至少一个除湿内机运行除湿状态，使所述至少一个除湿内机的蒸发器的容积和与当前运行的制热内机的冷凝器的容积和匹配；在一次分时除湿过程中的下一控制周期内，所述至少一个除湿内机停止运行除湿状态、并使另外的至少一个除湿内机运行除湿状态，所述另外的至少一个除湿内机的蒸发器的容积和与当前运行的制热内机的冷凝器的容积和匹配；依此循环，使得在一次分时除湿过程中，所述多个除湿内机中的每个除湿内机均运行一次除湿状态。

在此基础上，若一控制周期不是本次分时除湿过程中的最后一个控制周期，则控制模块10还配置为控制在该控制周期结束后，进入本次分时除湿过程中的下一个控制周期。
在此基础上，在本次分时除湿过程中若第一集合中的除湿内机和/或当前的制热内机发生调整，则控制模块10还配置为控制进入下一次分时除湿过程。

在此基础上，本公开一些实施例提供的多联机系统还包括编号模块30，编号模块30被配置为按照等差数列的规则，对所述第一集合内的除湿内机进行编号。
