从本文提供的描述，其它应用领域将变得显而易见。应当理解，这些描述及具体示例仅出于说明的目的而非意在限制本公开的范围。
附图说明
此处所描述的附图仅出于图示的目的，而并非意在以任何方式限制本公开的范围。
图1是制冷系统的示意图。
图2是压缩机的剖面图。
图3是示出用于根据本教示的算法的步骤的流程图。
图4是示出与吸入过热度和室外温度相关的排出过热度的图表。

具体实施方式
以下描述本质上仅是示例性的，而并非意图限制本公开、应用或用途。应当理解，附图中自始至终相应的附图标记指代相同或相应的部件和特征。
如本文所使用的，术语“模块”、“控制模块”以及“控制器”指的是以下各项中的一个或多个：专用集成电路(ASIC)、电子电路、执行一个或多个软件程序或固件程序的处理器(共享的、专用的、或群机的)和存储器、组合逻辑电路、或提供所述功能的其它适合的部件。如本文所使用的，计算机可读介质指的是能够存储计算机用数据的任何介质。计算机可读介质包括但不限于：内存、RAM、ROM、PROM、EPROM、EEPROM、闪存、CD-ROM、软盘、磁带、其它磁性介质、光学介质、或者能够存储计算机用数据的任何其它设备或介质。
参见图1，示例性制冷系统5包括压缩制冷剂蒸气的压缩机10。尽管图1中示出特定制冷系统，但是本教示可应用于任何制冷系统，包括热泵、采暖通风与空调(HVAC)和制冷机系统。来自压缩机10的制冷剂蒸气被输送至冷凝器12，在此制冷剂蒸气在高压下液化，从而将热量排放到外部空气。离开冷凝器12的液态制冷剂经膨胀阀14输送到蒸发器16。膨胀阀14可为用于控制制冷剂过热度的机械或电子阀。制冷剂通过膨胀阀14，在此压力下降使高压液态制冷剂成为低压液体和蒸气混合物。当热空气穿过蒸发器16时，低压液体变成气体，由此从蒸发器16带走热量。低压气体再被输送到压缩机10，在此被压缩成高压气体并被输送到冷凝器12，从而再次开始制冷循环。
压缩机10可由控制模块25监测和控制。控制模块25包括用于存储数据的计算机可读介质，所述数据包括由处理器执行的、用于监测和控制压缩机10并用于实现本教示的算法的软件。
如在题为“VARIABLE SPEED COMPRESSOR PROTECTIONSYSTEM AND METHOF(变速压缩机保护系统及方法)”的美国申请系列号No.60/978,258的公开文本——通过参引将其结合入本文——中描述的，可利用吸气过热度(SSH)来监测或预测压缩机10的过热状态。如本文所述，过热状态是不合期望的，并且可能对压缩机10、压缩机部件或制冷系统部件造成损害。
压缩机回液或过热状态是不合期望的并且可能对压缩机10或其它制冷系统部件造成损害。吸入过热度(SSH)和/或排出过热度(DSH)可能与压缩机10的回液或过热状态相关并且可以进行监测以检测和/或预测压缩机10的回液或过热状态。DSH是离开压缩机的制冷剂蒸气的温度(称为排出管路温度(DLT))与冷凝器饱和温度(Tcond)之间的温差。吸入过热度(SSH)是进入压缩机的制冷剂蒸气的温度(称为吸入管路温度(SLT))与蒸发器饱和温度(Tevap)之间的温差。
如图4所示，SSH和DSH可以是相关的。对于涡旋式压缩机而言，DSH和SSH之间的相关关系可特别精确，而外部环境温度仅为次要影响。如图4所示，示出了对于室外温度(ODT)为一百一十五华氏度、九十五华氏度、七十五华氏度以及五十五华氏度的DSH和SSH之间的相关关系。图4中所示的相关关系仅是示例性的，并且特定压缩机的特定相关关系会因压缩机类型、型号以及容量等而变化。
当SSH接近零华氏度或当DSH接近二十至四十华氏度时，可能出现回液状态。关于过热，当SSH介于三十华氏度和五十华氏度之间时，可能开始出现过热状态。当SSH大于五十华氏度或当DSH大于一百华氏度时，可能出现严重的过热状态。
在图4中，示出了针对示例性制冷剂充料程度的典型SSH温度。例如，随着制冷系统5中的制冷剂充料百分比减少，SSH通常增大。
参见图1，蒸发器16可包括能够感测蒸发器温度的蒸发器温度传感器40。可替代地，可使用蒸发器压力传感器。控制模块25接收来自蒸发器温度传感器40的蒸发温度(Tevap)。
吸入传感器34监测进入压缩机10的制冷剂的温度(即SLT)。可替代地，可使用吸入温度/压力传感器的组合。在这种情况下，由于可基于吸入压力而推导出或测出Tevap，所以控制模块25可从传感器的温度部分接收SLT和从传感器的压力部分接收Tevap。此外，如在题为“VARIABLE SPEED COMPRESSOR PROTECTION SYSTEM ANDMETHOD(变速压缩机保护系统及方法)”的美国申请序列号No.60/978,258的公开——通过参引将其结合入本文——中描述的，可从其它系统参数推导出Tevap。
例如，Tevap可作为Tcond和DLT的函数而推导出，如在共同受让的美国申请No.11/059,646、美国公开No.2005/0235660中描述的。对于变速压缩机，该相关关系还能够反映出压缩机速度。通过这种方式，Tevap可作为Tcond、DLT以及压缩机速度的函数而推导出。
如图5所示，示出了对于不同的Tcond水平，与DLT相关的Tevap。为此，可使用针对不同速度的压缩机特性线图(compressor map)数据。
可基于简单的推导而计算出Tcond和Tevap。
此外，可基于以下方程进行迭代计算：
方程1：Tcond＝f(压缩机功率，压缩机速度，Tevap)
方程2：Tevap＝f(Tcond，DLT，压缩机速度)
可对这些方程进行多次迭代以实现收敛。例如，三次迭代可提供较理想的收敛。如上所述，可使用较多次或较少次迭代，或者不迭代。
还可利用针对不同速度的压缩机特性线图数据并基于DLT和压缩机功率而基于以下方程来确定Tevap和Tcond：
方程3：Tevap＝f(压缩机功率，压缩机速度，DLT)
方程4：Tcond＝f(压缩机功率，压缩机速度，DLT)
控制模块25可计算Tevap或从传感器34的压力部分接收Tevap数据。然后，控制模块25可计算作为SLT和Tevap之差的SSH。
如图1所示，吸入传感器34位于压缩机10外部并且当制冷剂进入压缩机10的吸入口时监测制冷剂的温度。可替代地，可使用位于压缩机内部的吸入传感器。如图2所示，吸入传感器32可设置在压缩机10的机壳内。在这种情况下，SLT可经由接线盒24通过电连接而通信至控制模块25。
控制模块25可通过将SSH与预定的过热度阈值进行比较而监测压缩机10的过热状态。如图3所示，在步骤302，控制模块25接收SLT数据。在步骤304，控制模块25从蒸发器温度传感器40接收Tevap。在步骤306，控制模块25基于SLT和Tevap计算SSH。可替代地，可基于其它感测的参数来估测或推导Tevap，如在上文和题为“VARIABLE SPEED COMPRESSOR PROTECTION SYSTEM ANDMETHOD(变速压缩机保护系统及方法)”的美国申请序列号No.60/978,258的公开——通过参引将其结合入本文——中描述的。
在步骤308，控制模块将SSH与预定阈值进行比较以判断是否存在过热状态。
当SSH介于零华氏度与三十华氏度之间时，控制模块25可判定压缩机10在正常温度范围内运行。当SSH介于三十华氏度与五十华氏度之间时，控制模块25可检测出过热状态并采取响应措施。高于五十华氏度的SSH温度可表明包括压缩机涡旋体、轴承等在内的压缩机部件有被损坏的风险。
控制模块25还可在预定的时间段内判断SSH是否大于预定阈值。例如，控制模块25可在预定的时间段内判断何时SSH介于三十华氏度与五十华氏度之间或何时高于五十华氏度。例如，该预定时间段可以是几分钟(如一分钟、两分钟、五分钟等)。第一预定时间段(如五分钟)可用于监测SSH何时介于三十华氏度与五十华氏度之间。短于第一预定时间段的第二预定时间段(如一分钟或两分钟)可用于监测SSH何时大于五十华氏度。应当理解，任何时间段都可用来作为合适的时间段。
如在题为“VARIABLE SPEED COMPRESSOR PROTECTIONSYSTEM AND METHOD(变速压缩机保护系统及方法)”的美国申请序列号No.60/978,258的公开——通过参引将其结合入本文——中所述的，控制模块25可响应于过热状态而调节压缩机运行和/或调节膨胀阀14。在严重过热状态下，控制模块25可停止压缩机10的运行。控制模块25还可产生存在过热状态的警报或通知。
如图6所示，压缩机工作包线可提供最大回液和最大SSH限值。此外，在涡旋压缩机的情况下，可提供最大涡旋体温度限值(Tscroll)。此外，可提供最大马达温度(Tmotor)。如图6所示，可基于SSH而调节压缩机速度和膨胀阀14以确保压缩机运行处于压缩机工作包线以内。通过这种方式，可将SSH保持在如图6所示的可接受范围内。
例如，在SSH介于三十华氏度与五十华氏度之间时，控制模块25可降低压缩机速度或使膨胀阀14打开。当SSH大于五十华氏度时，控制模块25可停止压缩机25的运行。
