    • An accumulator is capable of preventing an excessive enlargement of the flow rate of a liquid refrigerant which is discharged from the accumulator, reducing the quantity of refrigerating machine oil which is accumulated in the accumulator, and maintaining a required quantity of refrigerating machine oil in a compressor. Liquid and a gas which circulate in a refrigerating and air-conditioning circuit are introduced into a first space by a suction pipe, and the gas refrigerant is discharged to a refrigerating and air-conditioning circuit through a gas passage pipe, a second space and a discharge pipe 5. A liquid-level maintaining mechanism prevents a rise in the height of the accumulated liquid introduced into the first space. When the height has been made to be not lower than a predetermined height, a gas communication mechanism moves liquid in the first space from the first space to the second space. A returning mechanism discharges refrigerating machine oil accumulated in the first space to the refrigerating and air-conditioning circuit.
    • 蓄能器能够防止从蓄电池排出的液体制冷剂的流量的过度扩大,减少积存在蓄电池中的冷冻机油的量,并将所需量的冷冻机油保持在压缩机 。 液体和在制冷空调回路中循环的气体通过吸入管引入第一空间,气体制冷剂通过气体通道管,第二空间和第二空间被排出到制冷空调回路 排出管5.液面维持机构防止引入第一空间的积聚液体的高度上升。 当高度已经达到不低于预定高度时,气体连通机构将第一空间中的液体从第一空间移动到第二空间。 返回机构将积存在第一空间的制冷机油排出到制冷空调回路。

    • A failure diagnosis apparatus for a refrigerating cycle had a problem that it has a low precision because the fluid is treated, and it is difficult to detect a foretaste of failure, absorb individual differences of real machine in the failure determination, and determine a cause of failure. Also, no cheap and practical diagnosis apparatus and method are provided. A plurality of instrumentation amounts concerning the refrigerant such as the pressure and temperature of the refrigerating cycle apparatus or other instrumentation amounts are detected, the state quantities such as composite variables are acquired by making the arithmetic operation on these instrumentation amounts, and whether the apparatus is normal or abnormal is judged employing the arithmetic operation results. If learning is made during the normal operation, a current state is judged, and if learning is made by compulsorily performing the abnormal operation, or if the abnormal operating condition is operated during the current operation, a failure foretaste such as a critical operation can be made from a change in the Mahalanobis distance. Thereby, the secure diagnosis can be implemented with a simple constitution.
    • 冷冻循环的故障诊断装置存在由于流体被处理而具有低精度的问题,难以检测出故障的前兆,在故障判定中吸收实际机器的个体差异,并且确定原因 失败。 另外,没有提供便宜实用的诊断装置和方法。 检测与制冷循环装置的压力,温度等制冷剂有关的多个仪表量,或其他仪表量,通过对这些仪表量进行算术运算,获得复合变量等状态量, 使用算术运算结果判断正常或异常。 如果在正常操作中进行学习,则判断当前状态,并且如果通过强制执行异常操作进行学习,或者在当前操作期间操作异常操作条件,则诸如关键操作的故障预测可以是 由马哈拉诺比斯距离的变化所造成。 因此,可以用简单的结构来实现安全诊断。
