摘要： In a parallel flow heat exchanger having an inlet manifold connected to an outlet manifold by a plurality of parallel channels, a spirally shaped insert is disposed within the refrigerant flow path in the inlet manifold such that a swirling motion is imparted to the refrigerant flow in the manifold so as to cause a more uniform distribution of refrigerant to the individual channels. Various embodiments of the spirally shaped inserts are provided, including inserts designed for the internal flow of refrigerant therethrough and/or the external flow of refrigerant thereover.

摘要： In compression systems having multiple sources of pulsation induced noise, provisions are made to reduce the noise by selectively varying the length of adjacent refrigerant lines leading to a common refrigerant manifold. Each of the refrigerant lines is associated with a particular noise source. The feature can be incorporated into compressors operating in parallel or in a single multi-rotor compressor having multiple suction or/and discharge ports. It is equally applicable to both discharge and suction ports.

摘要： A method is provided for mitigating two-phase refrigerant maldistribution in heat exchange channels of a parallel flow evaporator. An inlet manifold of the evaporator includes a first stage, at least one intermediate stage, and a final stage. Each stage includes an expansion chamber, a contraction chamber, and at least one heat exchange channel interconnecting the stage to an outlet manifold of the evaporator. The method includes throttling the two-phase refrigerant in the expansion chamber of each stage, flowing a portion of the throttled refrigerant through the at least one heat exchange channel to the outlet manifold, mixing and jetting the two-phase refrigerant in each contraction chamber to increase the velocity of the refrigerant, and passing the refrigerant out an exit of the outlet manifold.

摘要： A refrigerant system is provided with pulse width modulation control to adjust the amount of refrigerant compressed by a compressor. In one embodiment, a pulse width modulation control controls a suction modulation valve cycled between open and closed positions. In a second embodiment, the compressor itself is cycled between a position at which it compresses refrigerant and a position at which the compression elements are disengaged. In either embodiment, the control also cycles the expansion device in concert with cycling the pulse width modulation valve or the compressor. In this manner, pressure fluctuations in the refrigerant system do not exceed desirable levels. Typical cycle time for pulse width modulation control is between 5 and 30 seconds, and typical offset (delay) time for an expansion device may be between 0 and 3 seconds.
摘要翻译：制冷剂系统具有脉宽调制控制，以调节由压缩机压缩的制冷剂量。在一个实施例中，脉宽调制控制控制在打开位置和关闭位置之间循环的吸入调节阀。在第二实施例中，压缩机本身在其压缩制冷剂的位置与压缩元件脱离的位置之间循环。在任一实施例中，控制还使循环脉冲宽度调制阀或压缩机一起循环膨胀装置。以这种方式，制冷剂系统中的压力波动不超过期望的水平。脉冲宽度调制控制的典型周期时间在5到30秒之间，扩展设备的典型偏移（延迟）时间可能在0到3秒之间。

摘要： A refrigerant system providing enhanced performance over a wider range of operating conditions than traditional economized refrigerant systems. The system includes an economizer branch that connects a liquid outlet from a suction accumulator to an economizer inlet port of a compressor unit. The economizer branch includes a liquid refrigerant pump that delivers a non-evaporated liquid refrigerant portion from the suction accumulator into the economizer heat exchanger, where the liquid refrigerant portion evaporates, increasing thermodynamic potential of the main circuit refrigerant also flowing in through the economizer heat exchanger, and a formed vapor stream is delivered into the economizer inlet port of the compressor unit.
