摘要： A multi-zone HVAC&R system has its control programmed to provide diagnostic testing of air handling components and refrigerant components associated with each climate controlled zone in sequence. The control changes the original position of the corresponding component and a resultant change in a relevant operational parameter is sensed. If the actual change is outside of the tolerance band associated with the expected change, then the determination is made that the component under consideration is malfunctioning. The periodicity of a diagnostic procedure for a particular component is typically defined by its criticality and reliability level. If the change in the corresponding operation parameter is recorded and stored in the database, the component degradation can be observed over time and a prognostic prediction can be made when a particular component requires preventive maintenance or replacement.

摘要： A refrigerant cycle is disclosed having a number of compressors operating in tandem and supplying a compressed refrigerant to a refrigerant system. Discharge lines communicate a compressed refrigerant to a central discharge line for receiving flow from 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 discharge lines outwardly of the shell of the compressors. 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 compressor, 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，其具有串联运行的多个压缩机并将压缩的制冷剂供应到制冷剂系统。排放管线将压缩的制冷剂传送到中央排放管线，用于接收来自所有串联式压缩机的流量。控制器可操作以确定需要操作的压缩机数量，或者某些压缩机是否应关闭以满足负载要求。截止阀被放置在压缩机壳体外部的排出管线上。这可以在部分加载操作期间关闭。当关联的压缩机停止时，这些截止阀关闭，以防止制冷剂从操作压缩机通过关闭压缩机回流到系统吸入侧。此外，消除了压缩机内部排放止回阀两端的高压差，减少了通过排放管道的压缩机溢流的可能性。因此，提高了压缩机/系统性能，提高了可靠性。

摘要： A heat pump is provided with an improvement while switching from heating/cooling mode to a defrost mode. Prior to initiation of a defrost mode, an electronic expansion device is moved to an open position such that refrigerant can migrate between the indoor-outdoor heat exchangers. When the operation of the defrost cycle is initiated, there is a lower likelihood and severity of flooded starts, as the refrigerant, under existing pressure differential at system shutdown, will move to the heat exchanger that will be downstream of the compressor in the defrost mode. Thus, no flooded start will occur on the subsequent compressor start-up. After completion of the defrost cycle, the electronic expansion device is again opened prior to return to operation in the conventional heating/cooling mode. In case subsequent starts are in an identical mode of operation, the electronic expansion valve is kept closed during shutdown to minimize cyclic performance losses.
摘要翻译：在从加热/冷却模式切换到除霜模式的同时，热泵具有改进。在除霜模式开始之前，电子膨胀装置移动到打开位置，使得制冷剂可以在室内 - 室外热交换器之间迁移。当启动除霜循环的操作时，淹没启动的可能性和严重程度较低，因为系统关闭时现有压力差下的制冷剂将移动到除霜模式下将在压缩机下游的热交换器。因此，在随后的压缩机启动时不会发生溢流的启动。在除霜循环完成之后，电子膨胀装置在以往的加热/冷却模式返回操作之前再次打开。在后续启动处于相同操作模式的情况下，电子膨胀阀在关闭期间保持关闭以最小化循环性能损失。

摘要： A refrigerant system has a refrigerant circuit comprising a compressor for compressing a refrigerant and delivering it downstream to a condenser. A bypass line is provided around the condenser for selectively allowing at least a portion of refrigerant to bypass the condenser. Valves are provided on a line leading to the condenser and on the bypass line to individually control the flow of refrigerant. An expansion device is located downstream of the condenser, and an evaporator is located downstream of the expansion device. A reheat cycle is incorporated into the system. The reheat cycle includes a valve for selectively delivering at least a portion of refrigerant through a reheat heat exchanger, which is positioned in the path of air downstream of the evaporator. A control is provided for the system to achieve a desired level of dehumidification and temperature control to air being delivered into the environment to be conditioned.

摘要： The present invention relates to a way of reducing the amount of energy required to partially compress a refrigerant in a compressor operating in a rapidly cycled unloaded mode. A valve on a suction line is closed when the compressor moves to the unloaded condition. In this manner, the amount of energy required to partially compress the refrigerant in the compressor, at the unloaded condition, is dramatically reduced.

摘要： A variable speed drive is provided for a compressor in a refrigerant system. When a low load situation has been determined by the refrigerant system controls, the variable speed drive moves the compressor to a lower speed mode of operation. In this case, if a speed is so low that it cannot ensure adequate oil lubrication of the compressor elements, then the motor speed is periodically increased to a level that will ensure proper lubrication. In this manner, a variable speed drive compressor can be operated at an extremely low speed to precisely match load demand on a refrigerant system. The invention can be extended beyond refrigerant system applications and to any oil-lubricated compressors whose lubrication is speed dependant.
摘要翻译：为制冷剂系统中的压缩机提供变速驱动器。当由制冷剂系统控制确定了低负载情况时，变速驱动器将压缩机移动到较低速度的操作模式。在这种情况下，如果速度如此之低以至于不能确保压缩机元件的充分的油润滑，则电动机速度被周期性地增加到将确保适当润滑的水平。以这种方式，可以以极低的速度操作变速驱动压缩机，以精确地匹配制冷剂系统上的负载需求。本发明可以延伸到制冷剂系统应用之外，并且可以延伸到其润滑速度依赖的任何油润滑的压缩机。
