摘要： A tandem compressor refrigerant cycle with an economizer circuit is introduced to provide additional capacity and improve system efficiency. In this system, tandem compressors deliver compressed refrigerant to a common discharge manifold, and then to a common condenser. From the common condenser, the refrigerant passes to a plurality of evaporators, with each of the evaporators being associated with a separate environment to be conditioned. Each of the evaporators is associated with one of the plurality of compressors. By utilizing the common condenser, and yet a plurality of evaporators, the ability to independently condition a number of environments is achieved without the requirement of the same plurality of separate complete refrigerant circuits for each of the environments. In some embodiments, several of the plurality of compressors can be provided by compressor banks having its own plurality of compressors. Some of the compressors in the compressor bank can have intermediate injection ports to accept refrigerant vapor from the economizer circuit. In particular, the economizer circuit provides additional capacity to the evaporators with relatively high load requirements.

摘要： A heat pump refrigerant system has a compressor for delivering a compressed refrigerant to a reversing refrigerant flow control device. The reversing refrigerant flow control device selectively delivers refrigerant to an outdoor heat exchanger in a cooling mode of operation, and to an indoor heat exchanger in a heating mode of operation. Refrigerant from an outdoor heat exchanger passes through an expansion device to an indoor heat exchanger in a cooling mode, and from the indoor heat exchanger through an expansion device and to the outdoor heat exchanger in a heating mode. A reheat circuit includes a reheat heat exchanger positioned to be in the path of air delivered over the indoor heat exchanger and into an environment to be conditioned. The reheat heat exchanger and outdoor heat exchanger both are provided by microchannel heat exchangers. The reheat circuit is utilized to minimize or prevent refrigerant charge migration while operating at a wide spectrum of environmental conditions or switching between modes of operation.

An evaporator bypass line is provided for passing a portion of the refrigerant flow from the main refrigerant circuit after having traversed a firstpass of the economizer heat exchanger through the expander to partially expand it to an intermediate pressure and thence through a second pass of the economizer heat exchanger and into an intermediate pressure stage of the compression device.

摘要： A refrigerant system is provided with an expansion device that may be a thermostatic expansion device or an electronic expansion device. A bypass line selectively allows a portion of refrigerant to bypass the expansion device and to flow through a fixed restriction expansion device such as an orifice positioned in parallel configuration with the main expansion device. A valve selectively enables or blocks refrigerant flow through this bypass line depending on the volume of refrigerant required to circulate through the refrigerant system as defined by environmental conditions and a mode of operation. The valve can be a simple shutoff valve or a three-way valve selectively allowing or blocking refrigerant flow through a particular refrigerant line or lines. In one embodiment, the expansion device is the main expansion device for the refrigerant system. In the other embodiment, the expansion device is a vapor injection expansion device for expanding refrigerant for performing an economizer function. The present invention allows the use of a smaller expansion device, which can be more precisely controlled, while still allowing the accommodation of higher refrigerant mass flow when necessary.

摘要： A closed-loop reheat circuit decoupled from a main refrigerant circuit is provided as part of a refrigerant system. In the closed-loop reheat circuit refrigerant is flown through an auxiliary heat exchanger, at which it transfers heat to refrigerant in the main circuit, increasing its cooling and dehumidification potential prior to entering an evaporator. The closed-loop circuit also includes a reheat heat exchanger that is placed in the path of at least a portion of airflow having passed over an evaporator. The reheat heat exchanger reheats air supplied to a conditioned space to a desired temperature after sufficient amount of moisture has been removed from the air in the evaporator to provide a comfortable humidity level. By utilizing the closed-loop reheat circuit, a control for the overall refrigerant system becomes less complex and more flexible, and the refrigerant system operation turns out to be more reliable and satisfying a variety of environmental conditions and potential applications. Various features and options of the decoupled reheat circuit concept are also disclosed.

摘要： A fixed restriction is placed in a suction line leading to a compressor. The size of the restriction is selected to achieve a desired capacity reduction (correction) for the refrigerant system compressor. By selectively restricting the flow of refrigerant through the suction line, the capacity delivered by the compressor will be reduced. This allows a designer of a refrigerant system to utilize an available compressor of a specific size (displacement) to satisfy the desired system operating conditions and performance characteristics as well as application requirements. In embodiments, the refrigerant system may be provided with an economizer and unloader functions. The restriction may be placed in the compressor suction port, or in the suction line leading to the compressor. Further, a pair of parallel flow passages may communicate an evaporator to the compressor, with the restriction being placed in one and a solenoid valve placed in the other.

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。
