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.

摘要： Multi-circuit refrigerant systems are provided with better control over a dehumidification function. In one embodiment, system circuits have means of communication with each other through connecting lines and flow control devices operable on demand. In another embodiment, a single reheat heat exchanger is utilized for both circuits, ensuring heat transfer interaction between the circuits. In yet another embodiment, a control unit operates refrigerant circuits in such a way that if some circuits are in a reheat mode, the remaining circuits are either shut off or are in an enhanced reheat mode.

摘要： A refrigerant cycle is disclosed having a number of compressors operating in tandem. Discharge lines communicate a compressed refrigerant to a central discharge line for receiving flow all tandem compressors. A control is operational to determine a number of compressors need to be operated or whether some compressors should be shutdown to satisfy load requirements. Shutoff valves are placed on the compressor discharge lines, that can be shutdown during part load operation. These shutoff valves are closed when their associated compressors are stopped to prevent backflow of refrigerant from operating compressors through the shutoff compressors, and into the system suction side. Additionally, high pressure differential across the compressor internal discharge check valve is eliminated and the possibility of compressor flooding through a discharge line is reduced. Thus, compressor/system performance is enhanced and reliability is improved.
摘要翻译：公开了一种制冷剂循环，其具有多个串联运行的压缩机。排出管线将压缩的制冷剂传送到中央排出管线，用于接收所有串联式压缩机的流动。一个控制器可用于确定需要操作的压缩机的数量或是否应该关闭一些压缩机以满足负载要求。截止阀放置在压缩机排气管线上，可在部分负载运行期间关闭。这些截止阀在其关联的压缩机停止时关闭，以防止制冷剂从运行的压缩机通过关闭压缩机回流并进入系统吸入侧。此外，压缩机内部排放止回阀上的高压差被消除，压缩机通过排放管路溢流的可能性降低。因此，压缩机/系统性能得到增强并且可靠性得到改善。

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： A refrigerant cycle is provided with a control that monitors system conditions such as current, voltage or temperature at a compressor motor or refrigerant state conditions at compressor ports. A protection switch on the motor is operable to stop operation of the compressor should a system condition exceed a predetermined maximum. The control monitors a system condition, and determines that the system conditions indicates the protection switch may be actuated as the condition is moving toward the predetermined limit. Under such conditions, the control moves the compressor to a less loaded mode of operation such that it is less likely that the protection switch will actuate.
