下面通过附图和实施例，对本发明的技术方案做进一步的详细描述。
附图说明

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
图1为本发明一个实施例的温控方法的流程图。参照图1，本发明实施例的温控方法具体包括以下步骤：
S11、获取室内的实时温度和制冷系统的实时蒸发参数。
其中，制冷系统的实时蒸发参数包括蒸发器的蒸发温度和/或蒸发压力。
具体的，所述获取室内的实时温度，进一步包括以下实现步骤：采集室内各个分层的各个温度采集点的实时温度；计算各个分层的各个温度采集点的实时温度的平均温度，将所述平均温度作为室内的实时温度。
本实施例中，在室内空间根据需求在各个分层合理布置一定数量的温度传感器，将每个温度传感器均通过继电器连接到温度巡检仪上，每个温度传感器通过其前端的温度探头来采集温度数据给温度巡检仪，由温度巡检仪实现自动巡检。温度巡检仪依次显示每个温度传感器采集到的数据，然后将这些温度数据集中传输到控制装置的模拟量获取模块中。
可理解的，所述获取制冷系统的实时蒸发参数，进一步可通过布置于制冷系统的温度传 感器来采集蒸发温度，或通过布置于制冷系统的压力传感器来采集蒸发压力。
S12、根据所述实时温度与预设目标温度的温度差确定制冷系统的目标蒸发参数。
S13、根据所述实时蒸发参数与所述目标蒸发参数的差值确定制冷设备组当前所需的运行载荷量。
S14、根据所述运行载荷量控制制冷设备组的工作参数，以使制冷系统的实时蒸发参数达到所述目标蒸发参数。
本发明实施例提供的温控方法，通过采集室内的实时温度和制冷系统的实时蒸发参数，并根据室内实时温度与预设目标温度的温度差确定制冷系统的目标蒸发参数，采用模拟量方式来根据实时蒸发参数与目标蒸发参数的差值实时调整制冷设备组的工作参数，使制冷系统稳定地、连续不断的向室内按需供冷，进而使得室内的实时温度保持预设目标温度，从而确保室内温度波动度低且稳定性好。
本发明实施例提供的温控方法能够适用于建筑内部的温控方法，例如冷库、冰温贮藏保鲜库、室内空调以及数据中心等室内的温度控制，对此本发明不作具体限定。
本发明实施例提供的温控方法，由于能够确保室内温度波动度低且稳定性好，进而能够使室内保持在一个舒适的相对湿度范围。例如，对于室内空调系统可以提高室内舒适度。对于冷库、冰温贮藏保鲜库等，可以减少产品干耗，保证产品的品质。
在本发明实施例中，所述根据所述实时蒸发参数与所述目标蒸发参数的差值确定制冷设备组当前所需的运行载荷量，具体包括以下步骤：根据所述实时蒸发参数与所述目标蒸发参数的差值查找预设的映射关系表，以获取与所述差值对应的运行载荷量，所述映射关系表中包括有实时蒸发参数和目标蒸发参数的差值与运行载荷量之间的对应关系。
在本发明实施例中，制冷设备组的工作参数包括制冷设备组中处于工作状态的制冷设备的数量以及每一制冷设备中压缩机的运行机械频率等。进一步地，所述根据所述运行载荷量控制制冷设备组的工作参数，具体包括以下步骤：根据所述运行载荷量控制制冷设备组中处于工作状态的制冷设备的数量，以及处于工作状态的制冷设备中压缩机的运行机械频率。
本发明实施例中，在根据所述运行载荷量控制制冷设备组中处于工作状态的制冷设备的数量时，需要在制冷设备组允许运行的台数范围内进行控制，以保障室内的基本供冷，在室内大门被突然打开时也能保障室内内存储品的基本温度，如此就不会像传统压缩机的开停式调温一样，有温度骤变的风险。
在本发明的另一个实施例中，所述根据所述运行载荷量控制制冷设备组的工作参数，还包括以下实现步骤：
根据所述运行载荷量控制制冷设备组中处于工作状态的制冷设备的数量；
对每台运行中的制冷设备，根据制冷设备中蒸发器的实际过热度SHevaporator的变化来设置对应的电子膨胀阀的开度Oevaporator。
相应的，所述根据所述运行载荷量控制制冷设备组的工作参数，以使制冷系统的实时蒸发参数达到所述目标蒸发参数，具体包括：
若蒸发器的实际蒸发压力Fevaporator小于预设的目标蒸发压力Ftarget，则把设置后的开度Oevaporator输出至电子膨胀阀。
其中，目标蒸发压力Ftarget的值是由蒸发器的预设传热温差计算得出，所述计算的过程是用蒸发器的加热温度减去预设传热温差从而计算出蒸发器的目标蒸汽温度Ttarget，并查表得知目标蒸汽温度Ttarget所对应的目标蒸发压力Ftarget。
本实施例中，对室内各处的温度求均值以获得平均库温，即室内的实时温度，通过平均库温的变化来反映室内各处的温度变化情况。
具体的，在制冷设备允许运行的数量范围内，若室内的实时温度高于预设的最大允许值则增加制冷设备的运行台数，若室内的实时温度低于预设最小允许值则减少制冷设备的运行台数。
具体的，在电子膨胀阀的开度Oevaporator的允许范围内，若实际过热度SHevaporator高于最大允许值则增大电子膨胀阀的开度Oevaporator，若实际过热度SHevaporator低于最小允许值则减少电子膨胀阀的开度Oevaporator。
在实际应用中，事先设好室内的温度允许范围T min～T max、压缩机允许运行的台数范围S min～S max、电子膨胀阀的开度范围O min～O max和过热度范围SH min～SH max,然后才进行自动调温。通过来自各个温度传感器的温度数据计算出室内的实时温度即平均库温。接着，当平均库温T average高于温度T max且压缩机的运行台数S evaporator尚未多于S max，则增加压缩机的运行台数S evaporator，否则无动作。若平均库温T average低于温度T min且压缩机的运行台数S evaporator尚未少于S min，则减少压缩机的运行台数S evaporator，否则无动作。值得注意的是：之所以要把压缩机的实时运行台数控制在允许范围内，是为了保障室内的基本供冷，在室内大门被突然打开时也能保障室内内存储品的基本温度，如此就不会像传统压缩机的开停式调温一样，有温度骤变的风险。
为了实现防止湿压缩现象发生，提高制冷效率。该方法还包括从蒸发器的管体内部的温度传感器处获取实际蒸汽温度T evaporator，并从蒸发器的管体内部的压力传感器处获取实际蒸发压力F evaporator，并查表获知实际蒸发压力F evaporator所对应的饱和蒸汽温度T saturated，将实际蒸汽温度T evaporator减去饱和蒸汽温度T saturated从而计算出实际过热度SH evaporator。获得过热度SH evaporator后，若实际过热度SH evaporator高于SH max且电子膨胀阀的开度O evaporator尚未高于O max，则增大电子膨胀阀的开度O evaporator，否则无动作。若实际过热度SH evaporator低于SH min且电子膨胀阀的开度O evaporator尚未低于O min，则减少电子膨胀阀的开度O evaporator，否则无动作。
开度O evaporator确定后，只有在实际蒸发压力F evaporator小于目标蒸发压力F target，才会确定电子膨胀阀的开度O evaporator有效并输出至电子膨胀阀的驱动器中；若实际蒸发压力F evaporator不小于目标蒸发压力F target，说明蒸发器中的制冷液过多，此时不宜再继续给蒸发器加液，以免蒸发器在机械运转时发生液击，此时设置电子膨胀阀的开度O evaporator输出为零。其中，目标蒸发压力F target的获知过程如下：在蒸发器中，由于蒸发压力固定时，制冷液的沸点(即蒸汽温度)是固定的，因此加热制冷液的温度与沸点之差(即传热温差)也就得出了，因而可以通过反向思维，事先设置需要的传热温差，然后把实时的加热制冷液的温度减去传热温差，即可知道应该要使蒸发器达到的蒸汽温度(简称目标蒸汽温度T target)，从而得知为达到目标蒸汽温度T target所应对蒸发器施加的压力(目标蒸发压力F target)。
对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明实施例并不受所描述的动作顺序的限制，因为依据本发明实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本发明实施例所必须的。
