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 actual superheat value in a refrigerant system is compared to an expected superheat level. If the actual superheat valve exceeds a certain predetermined value, this is an indication of refrigerant charge loss or a malfunctioning expansion device. In one example, the superheat valve is determined by comparing a difference between a saturated vapor temperature and an actual operating vapor temperature. The superheat determination can be made either at evaporator exit, economizer heat exchange exit or near the compressor discharge port.

摘要： Multiple refrigerant circuits are operated in parallel, and each has an economizer cycle. One of the two circuits may have a greater capacity than the other. By controlling the two circuits to run in economized, conventional, bypassed, or economizer bypassed operation, the control is able to match demanded capacity. Moreover, by exercising similar technique, the control can provide better humidity control, can limit or maintain head pressure, and can avoid power consumption peaks.

摘要： A refrigerant cycle is provided with an economizer circuit. The amount of refrigerant passing through the economizer circuit can be gradually modulated by an expansion device whose position can be easily adjusted from fully open to fully closed or disengaged. In the past, economizer circuits have either been fully engaged or fully disengaged. Modulation of economizer flow allows for variable capacity operation. This improves unit operating efficiency, minimizes unit cycling and prevents compressor overloading at extreme of operating conditions. It also allows for head pressure and discharge temperature control.

摘要： Several control algorithms reduce the likelihood of insufficient oil return to the compressor. One algorithm is useful in a multi-circuit refrigerant system. A control reduces the cooling capacity of one of the circuits if the number of compressor start/stop cycles becomes excessive. By reducing the capacity, the control will reduce the number of compressor start/stop cycles for a circuit. In this manner, the oil continues to circulate through the circuit, and is more efficiently returned to the compressor. Another problem area associated with a poor oil return back to the compressor is when there is low mass flow rate of refrigerant circulating through the system. Various ways of increasing the refrigerant mass flow rate are disclosed to ensure proper oil return to the compressor . Also, if oil return problems are likely due to an undesirably high oil viscosity at the vapor portion of the evaporator or suction line, then steps are taken to reduce oil viscosity. Overall, the present invention discloses three distinct algorithms that may be utilized, either separately or in combination, to ensure better flow of oil back to the compressor. The invention enhances system and compressor reliability and performance as well as prevents the compressor damage.
摘要翻译：几种控制算法减少了回油不足的可能性。一种算法在多回路制冷剂系统中是有用的。如果压缩机启动/停止循环次数过多，控制器会降低其中一个回路的制冷量。通过减少容量，控制将减少电路的压缩机启动/停止周期数。以这种方式，油继续循环通过回路，并且更有效地返回到压缩机。与劣质油返回压缩机相关的另一个问题是制冷剂循环通过系统的质量流量低。公开了增加制冷剂质量流量的各种方式以确保适当的回油到压缩机。另外，如果回油问题可能是由于蒸发器或吸入管线的蒸汽部分的油粘度不合需要高，则采取步骤来降低油的粘度。总体而言，本发明公开了可以单独或组合使用的三种不同的算法，以确保更好的油回流到压缩机。本发明增强了系统和压缩机的可靠性和性能，并防止了压缩机的损坏。

摘要： A refrigerant cycle is provided with tandem compressors. Only some of the multiple compressors are provided with an economized cycle, and an optional unloader valve for selectively returning flow from an economizer injection port back to suction. The present invention thus provides the economized operation capabilities and benefits for a refrigerant cycle having tandem compressors, without the complexity of providing separate economizer arrangement for each of the compressors.
