具体实施方式
本发明实施例公开了一种空调的控制方法，实现了节能。
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考附图1，本发明实施例公开的空调的控制方法，包括以下步骤：
S1、获取空调的工作模式和目标舒适温度；
S2、检测室内温度，并计算室内温度与目标舒适温度的温度差△T；
S3、判断△T是否大于目标温度差值△T1，若是，则进入步骤S4，若否，则进入步骤S5；
S4、控制空调室内机的两个贯流风扇4和两个室内换热器均运转；
S5、控制空调室内机的其中一个贯流风扇4和与该贯流风扇4配合工作的室内换热器运转；
其中，工作模式包括制冷模式和制热模式；
空调室内机包括机壳1，设置在机壳1内的两个风道5和两个室内换热器，一一对应地设置在风道5内的两个贯流风扇4；机壳1的前面板上设置有与风道5一一连通的两个出风口3，后壳上设置有与风道5一一连通的两个进风口2。
由此可见，本发明提供的空调的控制方法根据室内温度与目标舒适温度的温度差△T控制空调室内机的两个贯流风扇4和两个室内换热器的运转；当△T大于目标温度差值△T1时，控制两个贯流风扇4和两个室内换热器均运转，通过两个出风口3向室内吹风，提高了换热效率；当△T不大于目标温度差值△T1时，控制其中一个贯流风扇4和与该贯流风扇4配合工作的室内换热器运转，通过一个出风口3向室内吹风即可满足换热需求，减小了耗电量，实现了节能，还能提高舒适性。
具体的，空调的空调室外机包括室外换热器和两个电子膨胀阀，两个电子膨胀阀分别与设置在室外换热器与两个室内换热器并联连接的两个管路上，通过电子膨胀阀分别控制相连的室内换热器的冷媒量和冷媒流速；在△T超过目标温度差值△T1时，打开两个电子膨胀阀控制两个贯流风扇4运转，达到增大出风量，提高换热效率的目的；在△T位于目标温度差值△T1以内时，打开一个电子膨胀阀控制一个贯流风扇4运转，达到节能并且提高舒适性的目的。
优选的，步骤S5中还包括根据△T控制贯流风扇4的转速。本发明在控制空调室内机的其中一个贯流风扇4和一个室内换热器运转时，根据室内温度与目标舒适温度的温度差△T的不同，控制贯流风扇4采用不同的转速；在△T较大时，采用较大的转速；在△T较小时，采用较小的转速，从而在满足换热需求的同时节能。
进一步的技术方案中，步骤S5中“根据△T控制贯流风扇4的转速”包括：当△T2≤△T≤△T1时，控制贯流风扇4的转速为高风速；当△T3≤△T＜△T2时，控制贯流风扇4的转速为中风速；当0＜△T＜△T3时，控制贯流风扇4的转速为低风速；其中，△T1＞△T2＞△T3；高风速＞中风速＞低风速。
本实施例将贯流风扇4的转速分为三个等级，将温差室内温度与目标舒适温度的 温度差△T分为三个范围，分别采用不同的风速，舒适性和节能性更好，采用不同的风速的同时通过控制相应的电子膨胀阀的开度，以匹配所需的换热量。当然，本发明还可以将转速分为其他等级如两个等级和四个等级，当然，也可以采用恒定的转速。
优选的，△T1为3℃，△T2为2℃，△T3为1℃。当2℃≤△T≤3℃时，控制贯流风扇4的转速为高风速；当1℃≤△T＜2℃时，控制贯流风扇4的转速为中风速；当0＜△T＜1℃时，控制贯流风扇4的转速为低风速。本实施例以2℃、1℃为界限，将不大于3℃的△T划分为三个范围，方便控制贯流风扇4的转速。当然，上述△T1、△T2、△T3还可以采用其他的温度值。
步骤S4中，控制贯流风扇4的转速为高风速。当△T大于目标温度差值△T1时，控制两个贯流风扇4采用较大的高风速，使两个出风口3的出风量达到最大，提高了换热效率。当然，本发明还可以将大于3℃的△T划分几个范围，根据范围的不同，来控制两个贯流风扇4的转速。
为了进一步优化上述技术方案，当获取的工作模式为制热模式时，步骤S4同时控制空调室内机的电加热管7工作。在偏冷的季节，利用电加热管7和室内换热器同时进行制热，提高了制热效果。
上述控制方法中，当获取的工作模式为制冷模式时，步骤S5还包括获取目标吹风模式；其中，空调的吹风模式包括随人吹风模式和避人吹风模式。本发明在制冷模式，△T位于3℃以内时，可以选择随人吹风模式和避人吹风模式，从而满足多样性需求。
具体的应用方案中，在制冷模式下，设置目标舒适温度为23℃；当检测到的室内温度高于26℃时，△T＞3℃，控制两个贯流风扇4和两个室内换热器均运转，同时贯流风扇4采用高风速；当检测到的室内温度不高于26℃时，△T≤3℃，控制单个贯流风扇4和单个室内换热器运转，并根据用户设定，选择随人吹风模式或避人吹风模式，同时在2℃≤△T≤3℃时，控制贯流风扇4的转速为高风速；在1℃≤△T＜2℃时，控制贯流风扇4的转速为中风速；在0＜△T＜1℃时，控制贯流风扇4的转速为低风速。
在制热模式下，设置目标舒适温度为22℃，当检测到的室内温度低于19℃时，△T＞3℃，控制两个贯流风扇4和两个室内换热器均运转，同时贯流风扇4采用高风速，双出风口3送风；当检测到的室内温度不低于19℃时，△T≤3℃，控制单个贯流风扇4和单个室内换热器运转，同时在2℃≤△T≤3℃时，控制贯流风扇4的转速为高风速；在1℃≤△T＜2℃时，控制贯流风扇4的转速为中风速；在0＜△T＜1℃时，控制贯流风扇4的转速为低风速。
如图2-7所示，本发明实施例还公开了一种空调，包括空调室内机，空调室内机包括机壳1，设置在机壳1内的两个风道5和两个室内换热器，一一对应地设置在风道5内的两个贯流风扇4；机壳1的前面板上设置有与风道5一一连通的两个出风口3，后壳上设置有与风道5一一连通的两个进风口2；用于检测室内温度的温度传感器；与温度传感器连接的控制器，控制器用于获取空调的工作模式和目标舒适温度，并计算室内温度与目标舒适温度的温度差△T，判断△T是否大于目标温度差值△T1，若是，则控制两个贯流风扇4和两个室内换热器均运转；若否，则控制其中一个贯流风扇4和与该贯流风扇4配合工作的室内换热器运转。
该空调工作时，首先通过控制器获取空调的工作模式和目标舒适温度；接着通过温度传感器检测室内温度，并通过控制器计算室内温度与目标舒适温度的温度差△T；接着控制器判断△T是否大于目标温度差值△T1，若是，则控制空调室内机的两个贯流风扇4和两个室内换热器均运转；若否，则控制空调室内机的其中一个贯流风扇4和与该贯流风扇4配合工作的室内换热器运转。
由此可见，本发明提供的空调的控制器根据室内温度与目标舒适温度的温度差△T控制空调室内机的两个贯流风扇4和两个室内换热器的运转；当△T大于目标温度差值△T1时，控制两个贯流风扇4和两个室内换热器均运转，通过两个出风口3向室内吹风，提高了换热效率；当△T不大于目标温度差值△T1时，控制其中一个贯流风扇4和与该贯流风扇4配合工作的室内换热器运转，通过一个出风口3向室内吹风即可满足换热需求，减小了耗电量，实现了节能。
具体的，空调的空调室外机包括室外换热器和两个电子膨胀阀，两个电子膨胀阀分别与设置在室外换热器与两个室内换热器并联连接的两个管路上，控制器通过控制电子膨胀阀的开度，分别控制相连的室内换热器的冷媒量和冷媒流速；在△T超过目标温度差值△T1时，打开两个电子膨胀阀控制两个贯流风扇4运转，达到增大出风量，提高换热效率的目的；在△T位于目标温度差值△T1以内时，打开一个电子膨胀阀控制一个贯流风扇4运转，达到节能并且提高舒适性的目的。
优选的，贯流风扇4的轴线沿竖直方向，且两个贯流风扇4沿机壳1的宽度方向并排布置，两个室内换热器分别对称布置在两个贯流风扇4所形成整体的左右两侧。机壳1的宽度方向指的是，机壳1的左右方向。本发明的空调室内机为空调柜机，采用两个贯流风扇4并排送风，风量较大，风速较高，送风距离较远，可以实现快速制冷制热，用户体验佳。
如图7所示，左侧的换热器位于左侧的贯流风扇4左侧，右侧的换热器位于右侧的贯流风扇4右侧，换热器位于整机侧边放置，两侧进风，空调柜机后侧无需预留进风间隙，减小了所需要占用的厚度空间。
可以理解的是，空调室内机还可以为空调挂机，换热风扇的轴线沿水平方向布置。
室内换热器为微通道蒸发器6，微通道蒸发器6与机壳1的前面板具有夹角，且微通道蒸发器6自前向后向内倾斜；此时，两个微通道蒸发器6均为平板状，对称布置在空调柜机的左右两侧，微通道蒸发器6的换热性能更佳，而且微通道蒸发器6更薄，方便布局，同时进一步减少占用空间。
同时，微通道蒸发器6与风道5在厚度方向上满足完全重合条件。需要说明的是，机壳1的厚度方向指的是，机壳1的前后即深度方向。满足完全重合条件指的是，完全重合或者基本重合；此时，微通道蒸发器6与风道5占用同样的厚度空间，在保证性能基础上能够最大程度地减小占用的厚度空间，生产的空调柜机厚度可以为做到180-240mm，在行业上首创超薄空调柜机。
当然，微通道蒸发器6也可以只有一部分与风道5在厚度方向上重合。
可替换的，微通道蒸发器6还可以为弧形或者弯折状，只要能够相对于即可的前面板内凹均可。上述换热器还可以采用壳管式结构、套管式结构或者板式换热器。
具体的，微通道蒸发器6与机壳1的前面板之间的夹角为45°-65°，这样一来，能够在保证微通道蒸发器6的换热面积即换热效率的同时减小厚度尺寸，还能避免占用的宽度空间过大，使部件集成度更高。当然，根据实际换热需求，上述夹角还可以为其他值。
空调室内机还包括设置在风道5内的电加热管7，在偏冷的季节，利用电加热管7和室内换热器同时进行制热，提高了制热效果。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
