 本发明的最佳实施方式
下面结合附图对本发明的具体实施方式作进一步详细的说明。
本发明提出的风冷设备，如图1所示，包括箱体1和内胆2，内胆2安装于箱体1中，期内腔被分隔为第一间室3和第二间室4，第一间室3内安装有第一加热丝5，第二间室4内安装有第二加热丝6；该风冷设备采用单循环制冷系统实现制冷，该单循环制冷系统包括循环风道7、压缩机8和蒸发器9，设置于内胆2外的后侧；内胆2外的后侧还设置一部蒸发风机10，在蒸发风机10上安装有用于检测化霜温度的化霜传感器（图中未示出）；在第一间室3开上设有第一风门11，该第一风门11与循环风道7连接；在第二间室4上开设有第二风门12，该第二风门12与循环风道7连接。
在如图1提出的风冷设备的架构上，本发明提出其控制方法，旨在以单循环制冷系统实现双温度恒温控制，具体的，如图2所示，包括如下步骤：
步骤S21：启动压缩机和蒸发风机，打开第一风门和第二风门。
以该风冷设备启动制冷开始为例，在该风冷设备开机后，首选启动单循环制冷系统，并打开第一风门11和第二风门12，分别对第一间室3和第二间室4实施制冷。
步骤S22：判断两个间室的制冷温度是否均达到制冷要求。
在两个间室分别制冷期间，分别判断两个间室的制冷温度是否达到各自的制冷要求，在制冷一段时间后，两个间室的制冷存在两种情况：1、均达到制冷要求，均需要进入恒温调节；2、一个间室已达到其制冷要求需要进入恒温调节，另一个间室未达到其制冷要求，需要继续制冷。
基于上述两种情况，本发明提出的控制方法分别执行不同的步骤，当情况1先发生时，执行步骤S23：控制压缩机停机，打开第一风门和第二风门，并控制蒸发风机继续运行，以及启动第一加热丝和第二加热丝。
在两个间室均达到其制冷要求后，通过该步骤的控制，分别启动第一间室3的第一加热丝5，以及第二间室4的第二加热丝6，对两个间室实施恒温控制；在本发明实施例中，在蒸发器9后侧还设置有一个补偿加热丝13，在恒温控制时，通过补偿加热丝13的运行加速蒸发器9的化霜时间，迅速提高蒸发器9表面温度，通过蒸发风机10的运行对间室内的恒温控制实施补偿加热，具体的，在压缩机8停机进入恒温控制时，保持蒸发风机10的运行，保持第一风门11和第二风门12打开的状态，以及启动补偿加热丝13，两个间室在通过其自己的加热丝实施恒温调节时，补偿加热丝13的热量通过蒸发风机10的作用，经第一风门11进入第一间室3，经第二风门12进入第二间室4，分别对两个间室的温度实施补偿。
当情况2先发生，或者在步骤S23的恒温调节过程中，均发生一个间室需要加热，另一个间室需要制冷的情况时，以第一间室3需要制冷，第二间室4需要加热为例，执行
步骤S24：控制压缩机和蒸发风机运行，打开第一风门并关闭第二风门，以及启动第二加热丝。
启动压缩机8，蒸发风机10继续运行，打开第一风门11并关闭第二风门12，保持第二加热丝6启动运行，单循环制冷系统运行的冷风经第一风门11进入第一间室3，对第一间室3制冷，而因为第二风门12关闭，则第二间室2内不进入冷风，继续经第二加热丝6的运行加热，这期间，当第一间室3再次达到其设定制冷温度时，执行步骤S25：控制压缩机停机，并延迟至化霜温度达到第一设定温度时关闭第一风门。
在第一间室3再次达到其制冷要求后，控制压缩机8停机，获取化霜传感器检测的化霜温度，当化霜温度达到第一设定温度T1时，关闭第一风门11。
压缩机8停机后，即刻启动补偿加热丝13，辅助蒸发器9化霜，以便尽快提高蒸发器9的表面温度，为后续对间室的恒温调节做准备。
步骤S26：在第一风门关闭后延迟至化霜温度达到第二设定温度时开启第二风门。
第一风门11关闭后，第二间室4继续加热，获取化霜传感器检测的化霜温度，当化霜温度达到第二设定温度T2时，开启第二风门12，由于在压缩机8停机后至第二风门12开启的时间段内，补偿加热丝13已经开启运行，蒸发器9表面化霜温度较高，当第二风门12开启后，能够对第二间室4的加热进行补偿，以加快对第二间室4的恒温调节。
步骤S27：在第二间室满足加热温度时，关闭第二加热丝。
对于蒸发风机10的控制，当化霜温度达到第一设定温度T1时，也即步骤S25中关闭第一风门11时，控制蒸发风机10停机，此时补偿加热丝13已开启，对蒸发器9实施辅助化霜，以尽快提高化霜温度；当化霜温度达到第二设定温度T2时，也即步骤S26第二风门开启后，再次启动蒸发风机10运行，通过蒸发风机10的作用，更快速的对第二间室4的加热进行补偿，进一步加快对第二间室4的恒温调节，直至第二间室满足加热温度后关闭。
此后，若两个间室在恒温控制过程中，反复需要制冷或加热时，结合上述步骤给出的控制方案，两个间室通过同时制冷、同时加热、一个制冷一个加热的方式，均可单独实施恒温调节，与现有能够实现恒温控制的双蒸发器+双蒸发风机+两个加热丝+电磁阀的方式相比，由于本发明方案基于单循环制冷系统实现，结构设计和工艺均更加简化，以简化的结构和工艺设计实现了单风冷系统双温区风冷设备的恒温控制，更适于产业化应用。
上述步骤S26之后，在压缩机8再次启动时，需立即关闭第二风门12，也即，只要压缩机8运行，需立刻关闭当前正在加热的间室的风门，以避免冷风对加热的影响。
上述第一加热丝5和第二加热丝6启动后，均按照加热档位要求的通电率运行，对于补偿加热丝13则在开启后，按照100%通电率运行。
基于上述提出的风冷设备的控制方法，如图3所示，本发明提出的风冷设备还包括全风冷控制模块31、全加热控制模块32和单室风冷/加热控制模块33；全风冷控制模块31用于控制压缩机8和蒸发风机10运行，以及打开第一风门22和第二风门12；全加热控制模块32，用于控制压缩机8停机，打开第一风门11和第二风门12，并控制蒸发风机10运行；以及，启动第一加热丝5、第二加热丝6和补偿加热丝13运行；单室风冷/加热控制模块33，用于控制压缩机8和蒸发风机10运行，打开第一风门11并关闭第二风门12，以及启动第二加热丝6；在第一间室3达到设定制冷温度时，控制压缩机8停机，并延迟至化霜温度达到第一设定温度T1时关闭第一风门11；在第二间室4满足加热温度时，关闭第二加热丝12；以及在第一风门11关闭后延迟至化霜温度达到第二设定温度T2时打开第二风门12。
单室风冷/加热控制模块33包括蒸发风机控制单元331，用于在化霜温度达到第一设定温度T1时控制蒸发风机10停机；以及，在化霜温度达到第二设定温度T2时，控制蒸发风机10运行直至第二间室4满足加热温度。
本发明提出的风冷设备还包括补偿加热控制模块34，用于在压缩机8停机后启动补偿加热丝13，具体的，按照100%通电率启动补偿加热丝。
具体风冷设备实现恒温控制的控制方法已经在上述详述，此处不予赘述。
应该指出的是，上述说明并非是对本发明的限制，本发明也并不仅限于上述举例，本技术领域的普通技术人员在本发明的实质范围内所做出的变化、改型、添加或替换，也应属于本发明的保护范围。
