摘要： 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.
摘要翻译：在启动时操作压缩机的方法中，压缩机反向旋转短时间。压缩机是反向旋转时不会压缩液体的类型。目的是通过加热和搅拌油底壳中的油和制冷剂的混合物来从油中清除液体制冷剂。这导致更加良性的正向启动，因为较少的制冷剂被吸入到压缩机泵中，并且在起动时从压缩机中泵出的油的量被最小化。此外，油的粘度增加，轴承的润滑性提高。在短时间之后，反转停止，压缩机可以向前方开始旋转。反向旋转的短时间段根据系统条件而变化。在一个实施例中，通过在环境温度升高时减少反向运行时间可以发生变化。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。

摘要： A control algorithm is developed which takes corrective action in the event that system conditions indicate there may be an inadequate flow of lubricant in the system. In particular, if a discharge pressure is below a predetermined amount or if the suction modulation valve is throttled, there is a possibility of inadequate lubricant flow. The system control then turns off the condenser fan, and if that first step is not sufficient, may also turn on an evaporator heater and then control a suction modulation valve. A fail safe control loop also takes effect if the condition sensor appears to have failed.

摘要： A flash tank economizer includes a sensor for sensing a condition indicative of pressure in the flash tank, and when that pressure is found to equal or exceed the critical pressure of the particular refrigerant being used, a controller responsively closes a valve in the economizer vapor line to shut off the economizer. A sensor is also provided to sense the pressure at the compressor mid-stage, and if that pressure is found to exceed the pressure in the flash tank, the controller causes the flow control device to function so as to prevent the flow of refrigerant from the compressor mid-stage to the flash tank. Provision is also made for selectively draining refrigerant from the flash tank to reduce the pressure therein from a supercritical to a subcritical condition.

摘要： A refrigerant vapor compression system includes a flash tank economizer defining a separation chamber is disposed in the refrigerant circuit intermediate a refrigerant heat rejection heat exchanger and a refrigerant heat absorption heat exchanger. A primary expansion valve is interdisposed in the refrigerant circuit in operative association with and upstream of the refrigerant heat absorption heat exchanger and a secondary expansion valve is interdisposed in the refrigerant circuit in operative association and upstream of the flash tank economizer. A refrigerant vapor injection line establishes refrigerant flow communication between an upper portion of the separation chamber and an intermediate pressure stage of the system's compression device and a suction pressure portion of the refrigerant circuit. A refrigerant liquid injection line establishes refrigerant flow communication between a lower portion of said separation chamber and an intermediate pressure stage of the compression device and a suction pressure portion of the refrigerant circuit.
