摘要： A refrigeration system for cooling air is disclosed. The system includes a substantially liquid refrigerant and an evaporator for transferring heat from the air to the substantially liquid refrigerant. The substantially liquid refrigerant becomes a low temperature, low pressure first substantially gaseous refrigerant. A compressor compresses the first substantially gaseous refrigerant into a high pressure, high temperature superheated second gaseous refrigerant. A lubricant circuit supplies lubricant to the compressor. A condenser rejects heat from the second gaseous refrigerant and forms a high pressure, lower temperature sub-cooled liquid refrigerant. The condenser has an output stream. A metering device transforms the sub-cooled liquid refrigerant into the substantially liquid refrigerant for the evaporator. A heat exchanger receives the first substantially gaseous refrigerant as a coolant on route to the compressor. The first substantially gaseous refrigerant is relatively cooler than the lubricant and the sub-cooled liquid refrigerant. The lubricant via the lubricant circuit flows through the heat exchanger and cools prior to entering the compressor and the sub-cooled liquid refrigerant flowing through the heat exchanger means sub-cools prior to entering the metering device.

摘要： A refrigerant system is provided with a suction pulse width modulation valve, and a pulse width modulation control for controlling this valve. System pressures, such as the pressure on the evaporator and the condenser are monitored. The measured system pressures are maintained within a band of acceptable lower and upper limits. As the pulse width modulation control cycles the valve, the refrigerant pressures in the evaporator and the condenser tend to fluctuate. The control ensures those fluctuations are within the limits by controlling the duty cycle of the valve.

摘要： To address the problem of lubricant entrainment within the refrigerant system components such as an evaporator and suction line, a control is provided to periodically, substantially and intermittently increase the refrigerant flow through these components to thereby carry the trapped lubricant back to the compressor. The increased flow of refrigerant can be accomplished by periodically throttling and then unthrottling either an expansion device or a suction modulation valve to cause instantaneous pressure buildup within a respective section of the vapor compression system and subsequent increase of the refrigerant flow through the above-referenced components such as an evaporator and suction line. Suggested time intervals of both the throttling and unthrottling states are provided, as well as the frequency of occurrence for subsequent oil return cycles.

摘要： A vapor compression cycle system is combined with a Rankine cycle system, with the two systems having a common suction accumulator from which the compressor draws refrigerant vapor for the vapor compression cycle system and from which a pump draws liquid refrigerant for circulation within the Rankine cycle system. The vapor from the Rankine cycle system expander is passed to the compressor discharge to provide a mixture which is circulated within the vapor compression cycle system to obtain improved performance. The heat exchangers are sized so as to obtain a non-complete evaporation, with the resulting two-phase fluid passing to the suction accumulator to provide liquid refrigerant to the Rankine cycle system and vapor refrigerant to the vapor compression cycle system.

摘要： A fuel-powered engine is provided to drive a mobile air conditioning or refrigeration unit such as a portable chiller, a container refrigeration unit, a portable packaged system, a transport tractor-trailer or truck refrigeration unit, etc. A control rapidly changes the engine speed between the predefined set of discreet engine speeds to precisely adjust the capacity of the refrigerant system. If the engine operates only at a single speed, then the control cycles the engine between this operating speed and a zero speed (the engine is shut off). If the engine can operate at multiple discreet speeds, then the control can cycle the engine between any of these speeds (including a zero speed). When a lower capacity is desirable, the engine operates for a longer time interval at a lower speed, and when a higher capacity is desirable, the engine operates for a longer period of time at a higher speed. The cycle rate is selected to control the comfort (e.g. temperature and/or humidity) of the conditioned environment within the specified tolerance band, while conforming to the reliability requirements.
摘要翻译：提供燃料动力的发动机来驱动移动空调或制冷单元，例如便携式冷却器，容器制冷单元，便携式包装系统，运输拖拉机拖车或卡车制冷单元等。控制快速地改变发动机在预定的一套离散发动机速度之间的速度，以精确地调节制冷剂系统的容量。如果发动机仅以单个速度运行，则控制器将使发动机在该运行速度和零速度之间循环（发动机关闭）。如果发动机可以以多个谨慎的速度运行，则控制器可以在任何这些速度（包括零速度）之间循环发动机。当需要较低的容量时，发动机以较低的速度运转更长的时间间隔，并且当需要更高的容量时，发动机以更高的速度运行更长的时间段。选择循环速率以在符合可靠性要求的情况下控制在规定的公差带内的调节环境的舒适度（例如温度和/或湿度）。

摘要： A superheat control utilizes a sensor at a location downstream of an evaporator after some heat is delivered to the refrigerant. In one embodiment, the compressor is a sealed compressor with at least a portion of the refrigerant being heated by an electric motor. The temperature is sensed after the refrigerant temperature has increased after passing over the electric motor. In another embodiment, the refrigerant temperature is measured after some minimal compression and minimal temperature rise has occurred within the compressor pumping elements. In either case, by measuring the temperature of the refrigerant after some additional heat has been added to the refrigerant, the refrigerant super-heat leaving the evaporator can be controlled to a lower value. The improved superheat control enhances the system performance by increasing system efficiency, system capacity and improving oil return to the compressor.
