摘要： Variable speed drives are utilized in refrigerant systems to operate motors of the system components at varying speeds, typically for the purposes of capacity adjustment, efficiency enhancement, reliability improvement or power consumption limitation. However, variable speed controls are expensive. The present invention offers flexibility to utilize a variable speed drive to provide variable speed functionality between compressor and fans (or other rotating components having electric motors) within a refrigerant system depending on operational and environmental conditions and external load demands. The switching device switches the variable speed drive between component motors as indicated by a control for the refrigerant system.

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： A refrigerant system can be operated in either vapor injection mode or unloaded mode. A restriction to the vapor injection flow is incorporated into the refrigerant system. The restriction is placed on the vapor injection line upstream of a point where the injection line meets the unloader line. In this case, the flow is restricted for the vapor injection mode of operation to a desired level. However, when the refrigerant system operates in the unloaded mode, there is no restriction to the by-pass flow, which is beneficial to the system performance in this mode of operation. In one of the embodiments, the restriction area can be adjusted to achieve the best performance during the vapor injection mode of operation in relation to the operating conditions.
摘要翻译：制冷剂系统可以以蒸气喷射模式或卸载模式运行。对蒸汽注入流的限制被并入到制冷剂系统中。该限制被置于喷射管线与卸载器线路相交的点的上游的蒸气喷射管线上。在这种情况下，流量被限制为蒸汽喷射操作模式到期望的水平。然而，当制冷剂系统以卸载模式运行时，对旁路流量没有限制，这有利于在该操作模式下的系统性能。在其中一个实施例中，可以调整限制区域以在蒸气喷射操作模式期间相对于操作条件达到最佳性能。

摘要： A refrigerant system is provided where the functions of an economizer heat exchanger and liquid-suction heat exchanger are combined. The two configurations are disclosed with a single common heat exchanger construction. In a first configuration, a series of valves selectively routes only one of two possible refrigerant flows through a common heat exchanger such that a control can selectively activate either an economizer heat exchanger circuit or a liquid-suction heat exchanger function. In a second configuration, both refrigerant flows are passed to the common heat exchanger through separate fluid lines and are selectively activated by the control. Variations of the second configuration are also disclosed.

摘要： In a shell-and-tube heat exchanger with the tubes disposed within the shell for conducting the flow of a fluid to be in heat transfer interaction with a refrigerant contained in the volume formed by the heat exchanger shell and the external surfaces of the tube bundle, the tubes are elongated in their cross-section, with the elongation axis being oriented in the vertical direction to thereby enhance the heat transfer process and potentially reduce the heat exchanger size or tube count. The design features can be applied to both flooded and falling film heat exchangers and are equally applicable to both evaporators and condensers.

摘要： A tandem compressor refrigerant system where an economizer circuit and reheat coil are incorporated to provide additional flexibility and control over overall system capacity and sensible heat ratio as well as to increase 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 or several of the plurality of compressors. By utilizing the common condenser, yet a plurality of evaporators, the ability to independently condition a number of sub-environments is achieved without the requirement of the same plurality of complete separate refrigerant circuits for each compressor. In particular, the economizer circuit provides additional capacity to any of the evaporators that have a relatively high load while the reheat coil provides improved dehumidification. Various design schematics and system configurations are disclosed.

摘要： A tandem compressor system is utilized that receives refrigerant from a common suction manifold, and from a common evaporator. From the compressors, the refrigerant passes to a plurality of condensers, with each of the condensers being associated with a separate zone for heat rejection, preferably at different temperature levels. Each of the condensers is associated with at least one of the plurality of compressors. A reheat coil is associated with the evaporator to improve comfort level in the environment to be conditioned. Multiple reheat circuits associated with separate condensers are employed to provide various stages of reheat or to condition separate environments. By utilizing the common evaporator, a plurality of condensers, and the reheat coils, the ability to independently control temperature, humidity and amount of heat rejection to a number of zones is achieved without the requirement of having dedicated circuits with multiple additional components. Thus, the overall system cost and complexity is significantly reduced and its operational and control flexibility is improved.
