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.

摘要： A refrigerant system is provided with a variable speed drive for at least one of its fluid-moving devices, wherein the variable speed drive is provided by an automated mechanical drive. In the disclosed embodiment, one of the pulleys for driving the fluid-moving device has a variable diameter to vary the speed at which the fluid-moving device is driven. The pulley may include two plates that are biased in one direction by a spring or permanent magnet force, and in an opposed direction by a hydraulic or electro-magnetic force. A control adjusts the amount of hydraulic or electro-magnetic force delivered to the plates to achieve a desired speed for the fluid-moving device.

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： An improved refrigerant system incorporates at least two circuits arranged in a cascaded relationship. Preferably, the upper circuit utilizes a hydrocarbon refrigerant and preferably the lower circuit utilizes CO 2 refrigerant. Preferably, the CO 2 cascaded circuit mainly operates in a subcritical region. To improve the efficiency and capacity control of the cascaded refrigerant system, at least one of the circuits is equipped with performance enhancement features such as, for example, an economized function provided by a flash tank or economizer heat exchanger. Additional enhancement features can also include a liquid-suction heat exchanger and bypass function.

摘要： A refrigerant system utilizes an expander, where at least partially expanded refrigerant portion is tapped at the intermediate expansion point and passed through an economizer heat exchanger. In the economizer heat exchanger, the tapped refrigerant further cools refrigerant in a main liquid line. The present invention eliminates the need for a separate dedicated economizer circuit expansion throttling device, by utilizing a single expander to provide this expansion function. This invention also allows for the recovery of the expansion work, otherwise lost in the economizer expansion throttling device. System capacity and efficiency are improved by providing additional thermal potential for the refrigerant expanded (partially or fully) in the expander during more efficient isentropic process. In various embodiments, there may be more than a single economizer circuit, with each of said economizer circuits receiving the tapped refrigerant portions from the expander at different intermediate expansion points.

摘要： A refrigerant system is provided with a pulse width modulation suction valve and a second valve on a line that bypasses the pulse width modulation suction valve. This second valve has a variable opening. In this manner, the pressure within the compressor shell is maintained at the lowest possible level regardless of the system operating conditions, when the pulse width modulation suction valve is cycled to a closed position. Further, the second valve can continue providing capacity control, should the pulse width modulation suction valve fail.
