摘要： A refrigerant system is provided with a variable speed drive for at least one of its fluid-moving devices, wherein the variable speed drive is provided by an automated mechanical drive. In the disclosed embodiment, one of the pulleys for driving the fluid-moving device has a variable diameter to vary the speed at which the fluid-moving device is driven. The pulley may include two plates that are biased in one direction by a spring or permanent magnet force, and in an opposed direction by a hydraulic or electro-magnetic force. A control adjusts the amount of hydraulic or electro-magnetic force delivered to the plates to achieve a desired speed for the fluid-moving device.

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.
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，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，但是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进入压缩机抽吸时，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，以在阀门故障时阻止压缩机，并在正常压缩机运行期间阻止制冷剂的流动。

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.
