    Abstract: In a method of operating a compressor at startup, the compressor is rotated in reverse for a brief period of time. The compressor is of a type that does not compress liquid when rotated in reverse. The purpose is to boil off the liquid refrigerant from the oil by heating and agitating the mixture of oil and refrigerant in the oil sump. This results in a much more benign forward start as less refrigerant is drawn into the compressor pump and the amount of oil pumped out of the compressor on start up is minimized. Also, the viscosity of oil is increased and lubrication of the bearings is improved. After a short period of time reverse rotation is stopped and the compressor can start rotating in the forward direction. The short period of time of reverse rotation is varied based upon system conditions. In one embodiment, the variation can occur by reducing the reverse run time as ambient temperature increases. In another embodiment, electrical conditions such as incoming voltage and/or a ratio of voltage to frequency can be utilized to change the reverse run time.

    Abstract translation: 在启动时操作压缩机的方法中，压缩机在短时间内反向旋转。 压缩机属于逆向旋转时不压缩液体的类型。 其目的是通过加热和搅动油槽中油和制冷剂的混合物来从油中蒸发液体制冷剂。 由于制冷剂吸入压缩机泵的次数减少，启动时从压缩机泵出的油量减到最小，这样可以带来更好的前向启动。 而且，油的粘度增加并且轴承的润滑被改善。 经过一段时间后，反向旋转停止，压缩机可以开始正向旋转。 反转的短时间段根据系统条件而变化。 在一个实施例中，该变化可以通过随着环境温度增加而减少反向运行时间来发生。 在另一个实施例中，可以利用诸如输入电压和/或电压与频率之比的电气条件来改变反向运行时间。

    Abstract: A refrigerant vapor compression system includes a compression device having at least a first compression stage and a second compression stage arranged in series refrigerant flow relationship. A first refrigerant heat rejection heat exchanger is disposed downstream with respect to refrigerant flow of the second compression stage. A first refrigerant intercooler is disposed intermediate the first compression stage and the second compression stage. The first refrigerant intercooler is disposed downstream of the first refrigerant heat rejection heat exchanger with respect to the flow of the first secondary fluid. An economizer includes a vapor line in fluid communication with a suction inlet to the second compression stage. A second refrigerant heat rejection heat exchanger is disposed intermediate with respect to refrigerant flow of the second compression stage and the first refrigerant heat rejection heat exchanger. A second refrigerant intercooler is disposed intermediate the first compression stage and the second compression.

    Abstract: A ventilation system includes a leak sensor (52), a controller (56), and at least one of an injection port (70) and a vent door. The leak sensor (52) is disposed within an interior space of a refrigerated container (10) and is arranged to provide a signal indicative of a concentration of a refrigerant (18) within the interior space. The controller (56) is arranged to receive the signal. At least one of the injection port (70) and the vent door is disposed on at least one of a floor (30), a front wall (32), and a side wall (38) of the refrigerated container (10).
