如果否，则判断所采集到的实际温度Troom与预设温度Tsetting的差值△T是否小于预设的最小温度差值A2，若是则继续关闭压缩机和冷却风机；若否则再判断门体是否关闭？如果是则启动冷却风机，如果否则关闭冷却风机。
实施例三
本实施例的结构与实施例二的结构的区别在于：本实施例中的制冷装置还包括相对保活间室独立设置的低温间室，且制冷组件中的蒸发器和冷却风机主要向低温间室内供冷，低温间室与保活间室之间设置有风门，通过该风门和冷却风机实现将低温间室内的冷量送入保活间室内。本实施例的控制方法与实施例二的区别在于：“保活间室内温度控制”及本实施例中增加了“低温间室制冷判断”。
请参见图8，所述“保活间室内温度控制”包括如下步骤：
判断风门是否关闭？
如果是，则判断所采集到的保活间室实际温度T2room与保活间室预设温度T2setting的差值△T2是否大于预设的保活间室最大温度差值A3，若是则打开风门和冷却风机；
如果否，则判断所采集到的保活间室实际温度T2room与保活间室预设温度T2setting的差值△T2是否小于预设的保活间室最小温度差值A4，若是则关闭风门和冷却风机。
请参见图9和图10，“低温间室制冷判断”位于“保活间室内温度控制”之前，其包括如下步骤：
判断压缩机是否关闭；
如果是，则判断所采集到的低温间室实际温度T1room与低温间室预设温度T1setting的差值△T1是否大于预设的低温间室最大温度差值A1？若是则启动压缩机和冷却风机，进而再判断风门是否打开？如是则进行后续判断；若否则再判断风门是否打开？如是则同样进行后续判断；
如果否，则判断所采集到的实际温度T1room与预设温度T1setting的差值△T1是否小于预设的低温间室最小温度差值A2，若是则关闭压缩机，并判断风门是否打开？如是则再进行后续判断，如否则关闭冷却风机；
上述“后续判断”为：判断保活间室的门体是否打开？若否则再判断冷却风机是否启动？如否则启动冷却风机。
实施例四
本实施例的结构与实施例一的结构的区别在于：保活制冷装置采用半导体制冷方式，所述制冷组件包括半导体制冷片和散热风机。由于结构的改变，从而使“保活间室内温度控制”与实施例一所有不同，请参见图11，所述“保活间室内温度控制”包括如下步骤：
判断半导体制冷片的电压是否为零？
如果是，则判断所采集到的实际温度Troom与预设温度Tsetting的差值△T1是否大于预设的最大温度差值A1，若是则使半导体制冷片和散热风机进行工作，若否则保持半导体制冷片的电压为零；
如果否，则判断所采集到的实际温度Troom与预设温度Tsetting的差值△T1是否小于预设的最小温度差值A2，若是则控制半导体制冷片和散热风机电压均为零；若否使半导体制冷片和散热风机进行工作。
综上所述，通过采用上述保活制冷装置的控制方法，可以使保活间室内的氧气达到动物所需要的量，从而避免动物致死，且节约能源。
尽管为示例目的，已经公开了本发明的优选实施方式，但是本领域的普通技术人员将意识到，在不脱离由所附的权利要求书公开的本发明的范围和精神的情况下，各种改进、增加以及取代是可能的。
