摘要： A refrigerant system is provided that includes a compressor, a motor for driving the compressor, a refrigerant system component, and a controller. The refrigerant system component can operate in a pulse width modulated mode having a loaded phase and an unloaded phase. The compressor motor is loaded in the loaded phase but unloaded in the unloaded phase. The controller applies a first voltage to the compressor motor in the loaded phase and a second voltage to the compressor motor in the unloaded phase. Here, the second voltage is less than the first voltage.

摘要： A pulse width modulation control is provided for a suction valve located on a suction line. When the flow rate through a refrigerant system needs to be reduced, the suction valve is rapidly cycled from an open position to a closed position. A bypass line connecting compressor discharge to compressor suction with a bypass valve and a discharge valve positioned on the discharge side of the compressor are also provided. When the control closes the suction valve, it also closes the discharge valve to prevent the refrigerant to backflow into the bypass line, and, at the same time, the control opens the bypass valve. Opening of the bypass valve reduces discharge pressure, leading to reduction in compressor power consumption and subsequent operating efficiency gain.
摘要翻译：为位于吸入管路上的吸入阀提供脉宽调制控制。当需要减少通过制冷剂系统的流量时，吸气阀从打开位置快速循环到关闭位置。还提供了将压缩机排放与压缩机抽吸与旁通阀连接的旁通管路和位于压缩机排放侧的排出阀。当控制器关闭吸入阀时，它还关闭排放阀，以防止制冷剂回流到旁路管路中，同时控制器打开旁通阀。旁通阀的打开减少排放压力，从而降低压缩机的功率消耗和随后的运行效率增益。

摘要： A heat pump refrigerant system is provided with at least two sequential stages of compression. An intercooler is positioned intermediate the two stages. The refrigerant flowing through the intercooler. is cooled by a secondary fluid such as ambient air. The intercooler is positioned to be in a path of air flow passing over an outdoor heat exchanger, and preferably upstream of the outdoor heat exchanger, in relation to this air flow. Benefits with regard to efficiency and capacity are achieved due to proposed system configuration in both heating and cooling modes of operation, while no additional circuitry or components are required to provide the intercooler function for the heat pump refrigerant system. This invention is particularly important for the CO2 heat pump refrigerant systems operating in the transcritical cycle.

摘要： A vapor compression system includes a timer and a controller for periodically starting up the system during the off-season periods (primarily non-cooling months) in which the system would normally be shut down. This provides periodic lubrication to the compressor components and prevents severe flooded starts due to excessive accumulation of refrigerant in the compressor (compressor oil sump in particular) and other system components. Provision is also made to sequentially turn on and off system components such as the compressor, the evaporator fan and the condenser fan to enhance the system operation. The timing sequences are provided for the time intervals between the startups, as well as the off-season operation cycle times.

摘要： A refrigerant system may utilize CO2 as a refrigerant. Should the sensed operating conditions indicate that the refrigerant might be approaching a condition at which the refrigerant could solidify, corrective actions are taken to prevent refrigerant transformation to a solid thermodynamic state. In one embodiment, hot gas from a compressor discharge is bypassed to a location upstream of the evaporator. In another embodiment, the high-side pressure of a refrigerant system is adjusted. In yet another embodiment, an additional charge of refrigerant is delivered on demand into the refrigerant system. In still another embodiment, a defrost cycle is initiated on demand. These embodiments prevent the refrigerant from approaching the conditions at which it may solidify.

摘要： A refrigerant system is provided with tandem compressors. A tandem compressor arrangement includes at least two compressors operating in parallel and having at least one common manifold. A control may operate the compressors either simultaneously, or in some predetermined sequence to provide control over refrigerant system capacity.

摘要： A refrigerant system control operates tandem compressors. If one of the monitored system conditions does not change as each of the tandem compressors or associated components is brought on line, then a determination is made that the respective component is malfunctioning. A refrigerant system can also be additionally equipped with other functions and components, such as variable speed drive, economizer circuit, unloader bypass, and reheat circuit. In case of a reheat circuit, the system can consist of single or multiple compressors. The control algorithm can also be updated such that that particular malfunctioning component is eliminated from the operational sequence.

摘要： A refrigerant system utilizes environmentally friendly natural refrigerant such as carbon dioxide. A pressure relief mechanism such as pressure relief valve is incorporated into the refrigerant system design to allow for at least some amount of refrigerant to be released to atmosphere to provide safe operation or comply with agency regulations if pressure within the refrigerant system exceeds a certain limit. This release can occur during refrigerant system storage, transportation or operation. A detection device such as an electrical circuit is included into the refrigerant system design to provide an indication that pressure relief valve has opened, such that the determination can be made by a refrigerant system control or an operator whether the refrigerant system needs to be recharged and whether it can continue its normal operation, narrow its operational envelope or shut down until the refrigerant charge can be restored.

摘要： A parallel-flow evaporator has a liquid trap for regulating velocity of refrigerant delivered to an evaporator from an expansion device. In its simplest configuration, the liquid trap is a u-shaped pipe positioned vertically and connected to an inlet manifold of the evaporator. By providing a liquid trap, a small amount of liquid refrigerant separates from the vapor phase at certain conditions. This separated liquid will tend to collect in the trap, and reduce a flow cross-sectional area of the line leading to the inlet manifold of the evaporator. As this cross-sectional area decreases, the velocity of the refrigerant passing through the line will increase. In this sense, as a small amount of liquid phase separates out, it will ensure that the velocity of the remaining refrigerant will increase such that further separation will be significantly reduced or entirely avoided. As a result, homogeneous refrigerant flow is provided to the evaporator, resulting in its performance enhancement and system reliability improvement.
摘要翻译：并联蒸发器具有液体捕集器，用于调节从膨胀装置输送到蒸发器的制冷剂的速度。在其最简单的构造中，液体阱是垂直定位并连接到蒸发器的入口歧管的u形管。通过提供液体捕集器，少量液体制冷剂在某些条件下与气相分离。这种分离的液体将倾向于在捕集器中收集，并且减少通向蒸发器入口歧管的管线的流动横截面积。当该横截面积减小时，通过该线路的制冷剂的速度将增加。在这个意义上，当少量的液相分离出来时，它将确保剩余制冷剂的速度将增加，使得进一步的分离将被显着减少或完全避免。结果，向蒸发器提供均匀的制冷剂流，从而提高其性能并提高系统可靠性。

In one embodiment, the evaporator fan is driven in a reverse direction, and the air is guided to the outdoor environment. In other embodiments, a supplemental exhaust fan is utilized in conjunction with the evaporator fan. Also, a reheat circuit, hot gas bypass circuit, or specific features of a heat pump unit may be utilized to more efficiently perform the moisture removal.
