基于上述的空调器，本发明还提供了两种用于空调器的控制方法。
如图5所示，本发明的第一种控制方法包括以下步骤：
在空调器制冷运行时，
S10：获取每个第一支路内的制冷剂的流量。
示例性地，室内换气器包括四个第一支路，在每个第一支路上设置一个流量传感器，并使流量传感器与空调器的控制器进行通讯，以便流量传感器能够及时地将检测到的流量数据传输给控制器。
S20：计算各第一支路之间的流量差。
控制器接收到四个第一支路的流量之后，分别计算四个第一支路之间的流量差，然后以多个流量差的平均值或者最大的流量差为参数进行后续计算，当然，优选以最大的流量差进行后续的计算。
S30：获取室内机的进风温度。
示例性地，可以在室内机的机壳的进风口处设置温度传感器，并使温度传感器与空调器的控制器进行通讯，以便温度传感器能够及时地将检测到的温度数据传输给控制器。
S40：获取室内机的出风温度。
示例性地，与获取室内机的进风温度相类似，可以在室内机的机壳的出风口处设置温度传感器，并使温度传感器与空调器的控制器进行通讯，以便温度传感器能够及时地将检测到的温度数据传输给控制器。
S50：计算进风温度和出风温度之间的温度差。
控制器在获取到室内机的进风温度和出风温度之后，计算二者之间的温度差，该温度差＝进风温度－出风温度。
S60：获取第一支路的数量。
在实际应用中，可以将第一支路的数量预存在空调器的控制器内，使用时直接提取即可。
S70：根据流量差、温度差以及第一支路的数量获取转速。
控制器在获取到的流量差、温度差以及第一支路的数量之后，根据这三个参数来获取转速。
需要说明的是，在实际应用中，可以根据计算公式来计算转速，或 者也可以根据对照表来查询对应的转速，等等，这种灵活地调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
S80：使旋转构件按照转速转动。

需要说明的是，常数c具体数值可以通过试验进行测定。
优选地，本发明的控制方法还包括：获取空调器的匹数；根据匹数获取常数c的数值。

优选地，本发明的控制方法还包括：将流量差与预设值进行比较；如果流量差小于预设值，则不使旋转构件转动。
示例性地，预设值为1g/s，当各个第一支管之间的流向差均小于1g/s时，则不使旋转构件转动。
需要说明的是，预设值并不局限于上述的1g/s，例如，还可以是0.9g/s或者1.1g/s等等，本领域技术人员在实际应用中可以根据试验灵活地设定预设值的具体数值。
此外，还需要说明的是，在空调器制冷运行时，室外换热器上的分液器内的旋转构件的转速可以与室内换热器上的分液器内的旋转构件的转速保持一致，或者，也可以使室外换热器上的分液器内的旋转构件保持固定转速，再或者，还可以使室外换热器上的分液器内的旋转构件固定不动，等等，这种灵活地调整和改变并不偏离本发明的原理和范围均应限定在本发明的保护范围之内。
优选地，使室外换热器上的分液器内的旋转构件以最高转速转动。

S300：获取室外机的进风温度。
示例性地，可以在室外机的进风口处设置温度传感器，并使温度传感器与空调器的控制器进行通讯，以便温度传感器能够及时地将检测到的温度数据传输给控制器。
S400：获取室外机的出风温度。
示例性地，与获取室外机的进风温度相类似，可以在室外机的出风口处设置温度传感器，并使温度传感器与空调器的控制器进行通讯，以便温度传感器能够及时地将检测到的温度数据传输给控制器。
S500：计算进风温度和出风温度之间的温度差。
控制器在获取到室外机的进风温度和出风温度之后，计算二者之间的温度差，该温度差＝进风温度－出风温度。
S600：获取第二支路的数量。
在实际应用中，可以将第二支路的数量预存在空调器的控制器内，使用时直接提取即可。
S700：根据流量差、温度差以及第二支路的数量获取转速。
控制器在获取到的流量差、温度差以及第二支路的数量之后，根据这三个参数来获取转速。
需要说明的是，在实际应用中，可以根据计算公式来计算转速，或者也可以根据对照表来查询对应的转速，等等，这种灵活地调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
S800：使旋转构件按照转速转动。
控制器在根据流量差、温度差以及第二支路的数量获取转速之后，控制旋转构件按照该转速转动。示例性地，可以通过调整定子的电压值来控制旋转构件的转速。
优选地，“根据流量差、温度差以及第二支路的数量获取转速”的步骤具体包括：将流量差、温度差以及第二支路的数量代入下述计算公式，
S2＝(G2÷T2)×N2×k，
其中，S2为转速，G2为流量差，T2为温度差，N2为支路的数量，k为常数。
需要说明的是，常数k具体数值可以通过试验进行测定。
优选地，本发明的控制方法还包括：获取空调器的匹数；根据匹数获取常数k的数值。
也就是说，常数k的数值有多个，并与空调器的匹数相对应，在计算转速之前，先根据空调器的匹数确定相对应的常数k的数值。
优选地，本发明的控制方法还包括：将流量差与预设值进行比较；如果流量差小于预设值，则不使旋转构件转动。
示例性地，预设值为1g/s，当各个第一支管之间的流向差均小于1g/s时，则不使旋转构件转动。
需要说明的是，预设值并不局限于上述的1g/s，例如，还可以是0.9g/s或者1.1g/s等等，本领域技术人员在实际应用中可以根据试验灵活地设定预设值的具体数值。
此外，还需要说明的是，在空调器制热运行时，室内换热器上的分液器内的旋转构件的转速可以与室外换热器上的分液器内的旋转构件的转速保持一致，或者，也可以使室内换热器上的分液器内的旋转构件保持固定转速，再或者，还可以使室内换热器上的分液器内的旋转构件保持固定不动，等等，这种灵活地调整和改变并不偏离本发明的原理和范围均应限定在本发明的保护范围之内。
优选地，使室内换热器上的分液器内的旋转构件以最高转速转动。
最后，需要说明的是，当空调器由制冷模式切换为制热模式，或者 由制热模式切换为制冷模式时，需要改变旋转构件的旋转方向。示例性地，在空调器制冷运行时，室内换热器上的分液器内的旋转构件顺时针转动，而当空调器制热运行时，使该分液器内的旋转构件逆时针转动。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
