摘要： An inventive method of preventing unpowered reverse rotation in a compressor includes the steps of placing a solenoid valve at a location near compressor discharge. The valve is preferably actuated soon after the power to the motor is cut off, blocking the flow of refrigerant from expanding back toward the compression chambers of the compressor. The compressor is disclosed as a scroll compressor, but may also be a screw compressor. These two types of compressors are susceptible to undesirable unpowered reverse rotation when compressed refrigerant re-expands through the compression elements from the compressor discharge into the compressor suction. By blocking the flow of refrigerant, this unpowered reverse rotation is prevented. A high pressure switch can be positioned directly upstream of the solenoid valve to immediately stop the compressor if the valve malfunctions and blocks the flow of refrigerant during normal compressor operation. This high pressure switch will prevent the continued operation of the compressor with the blocked discharge line by sending a signal to a control to cut the power to the compressor motor. A pressure differential switch can be utilized in a similar manner to avoid undesirably high pressure differentials across the valve. Also, the valve itself may be equipped with the flow bypass that opens when pressure differential across the valve exceeds a safe limit.
摘要翻译：防止压缩机中无动力反向旋转的创新方法包括将电磁阀放置在压缩机排放附近的位置的步骤。优选地，在电动机的动力被切断之后，阀被很快地启动，从而阻止制冷剂的流动朝向压缩机的压缩室向后扩展。压缩机被公开为涡旋式压缩机，但也可以是螺杆式压缩机。当压缩的制冷剂通过压缩元件从压缩机排放物再膨胀到压缩机吸力中时，这两种类型的压缩机容易受到不需要的未动力反向旋转。通过阻止制冷剂的流动，防止了这种无动力的反向旋转。高压开关可以直接位于电磁阀的上游，以在阀门发生故障并在正常压缩机运行期间阻止制冷剂流动，立即停止压缩机。该高压开关将通过向控制器发送信号来切断压缩机电机的电力来防止具有堵塞的排放管路的压缩机的继续操作。可以以类似的方式使用压差开关，以避免跨越阀的不期望的高压差。此外，阀本身可以配备有流量旁路，当跨越阀的压力差超过安全极限时，该旁路将打开。

摘要： A refrigerant system utilizes an expander that provides a more efficient expansion process and recovers at least a portion of energy from this expansion process. At least a portion of refrigerant that has been at least partially expanded in the expander is tapped and passed through an economizer heat exchanger. In the economizer heat exchanger, the tapped refrigerant cools a main circuit refrigerant increasing its thermodynamic potential. Further, a compression section is provided with at least two compressors operating in tandem and allowing for multiple stages of unloading. By selectively utilizing one or more of the tandem compressors, the economizer cycle, and the expander, the refrigerant system can achieve very efficient operation and provide enhanced control flexibility, in particular, for the CO 2 refrigerant system operating in the transcritical cycle.

摘要： A refrigerant system incorporating a reheat circuit is also provided with pulse width modulation control to adjust the amount of refrigerant being compressed. In particular, in any dehumidification mode of operation, by activating the pulse width modulation control, sensible and latent components of capacity can be controlled independently and with significantly better accuracy. The present invention provides the ability to precisely tailor both humidity and temperature control to the conditioned space demands utilizing less expensive components and in a more efficient manner than in the prior art.

摘要： A pulse width modulation control is provided for a suction valve on a suction line, delivering refrigerant into a housing shell of a compressor. When the suction valve is closed, the pressure within the housing shell can become very low. Thus, a pressure regulator valve is included within the refrigerant system to selectively deliver a limited amount of refrigerant into the housing shell when the suction valve is closed. The delivery of this limited amount of refrigerant ensures that a specified pressure is maintained within the housing shell to achieve the most efficient operation while at the same time preventing problems associated with damage to electrical terminals, motor overheating and excessive discharge temperature.
