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： A multiple circuit refrigerant system includes a single economizer heat exchanger utilized for each of at least two circuits. The use of the single economizer heat exchanger reduces the cost of adding an economizer cycle, and further reduces other associated costs. Additionally, heat exchanger and overall system performance is enhanced further. Embodiments show the inclusion of two, three and four circuits, although greater numbers may also benefit form this invention.

摘要： A refrigeration system for cooling air is disclosed. The system includes a substantially liquid refrigerant and an evaporator for transferring heat from the air to the substantially liquid refrigerant. The substantially liquid refrigerant becomes a low temperature, low pressure first substantially gaseous refrigerant. A compressor compresses the first substantially gaseous refrigerant into a high pressure, high temperature superheated second gaseous refrigerant. A lubricant circuit supplies lubricant to the compressor. A condenser rejects heat from the second gaseous refrigerant and forms a high pressure, lower temperature sub-cooled liquid refrigerant. The condenser has an output stream. A metering device transforms the sub-cooled liquid refrigerant into the substantially liquid refrigerant for the evaporator. A heat exchanger receives the first substantially gaseous refrigerant as a coolant on route to the compressor. The first substantially gaseous refrigerant is relatively cooler than the lubricant and the sub-cooled liquid refrigerant. The lubricant via the lubricant circuit flows through the heat exchanger and cools prior to entering the compressor and the sub-cooled liquid refrigerant flowing through the heat exchanger means sub-cools prior to entering the metering device.

摘要： A refrigeration system for cooling air s disclosed. The system includes a substantially liquid refrigerant and an evaporator for transferring heat from the air to the substantially liquid refrigerant. The substantially liquid refrigerant becomes a low temperature, low pressure first superheated gas refrigerant. A compressor compresses the first superheated gas refrigerant into a high pressure, high temperature second further superheated gas refrigerant. A lubricant circuit supplies lubricant to the compressor, wherein a portion of the lubricant is mixed with the further superheated gas refrigerant. A condenser rejects heat from the second superheated gas refrigerant and forms a high pressure, low temperature sub-cooled liquid refrigerant. The condenser has an output stream. A metering device transforms the sub-cooled liquid refrigerant into the substantially liquid refrigerant for the evaporator. An economizer circuit provides an intermediate temperature and pressure economizer refrigerant flow to the compressor. The economizer refrigerant flow originates from the output stream of the condenser. The economizer circuit includes an economizer heat exchanger. The economizer heat exchanger includes paths for receiving and cooling the lubricant before returning to the compressor and the sub-cooled liquid refrigerant on route to the metering device, wherein the economizer refrigerant flow is a cooling medium in the heat exchanger.

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 vapor compression system includes a main vapor compression circuit including a compressor, a condenser, an expansion device and an evaporator serially connected by main refrigerant lines, the compressor having a main discharge port, a suction port and an economizer/bypass port, an economizer circuit connected between the condenser and the economizer/bypass port of the compressor and including an auxiliary expansion device and a heat exchanger serially connected by economizer refrigerant lines, the economizer refrigerant lines and the main refrigerant lines being exposed to each other for heat exchange in the heat exchanger; and a bypass circuit including a bypass line extending from the economizer/bypass port to the suction port, and a bypass valve positioned along the bypass line, the bypass valve being positionable between a closed position wherein the economizer circuit is active and the bypass circuit is inactive, and an open position wherein the economizer circuit is active and the bypass circuit is active. The system and method advantageously allow for the economizer circuit and bypass circuit to be operational at the same time. By using an electronically controlled auxiliary expansion device, four modes of operation are permissible. As a result, life cycle and system costs can be reduced and compressor reliability and system performance can be enhanced. Additionally the control scheme and method extend the system operating envelope, hence preventing nuisance shutdowns, and further improving compressor reliability.

摘要： The invention provides two distinct schematics allowing system performance enhancement through the utilization of an auxiliary heat exchanger and splitting the refrigerant flow into primary and secondary paths. A system performance boost is achieved due to extra subcooling of a primary refrigerant flow in an auxiliary heat exchanger as well as superheat reduction of the combined refrigerant flow entering the compressor and a primary refrigerant flow pressure drop decrease through the evaporator (in comparison to the prior art). The invention offers the superior benefits outlined above with only a moderate cost increment. Also, employment of conventional components only, and no compressor modifications make implementation of the proposed schematics even more attractive.
摘要翻译：本发明提供了两个截然不同的原理图，通过利用辅助热交换器并将制冷剂流分解成主要和次要路径来提高系统性能。由于辅助热交换器中的初级制冷剂流的过度冷却以及进入压缩机的组合制冷剂流的过热减少以及通过蒸发器的初级制冷剂流量压降降低（与之前相比），系统性能提升是实现的艺术）。本发明提供了上述优点，只有适度的成本增量。而且，仅使用常规部件，并且没有压缩机修改使得所提出的示意图的实现更具吸引力。

摘要： A method for detecting compressor degradation includes the steps of providing a dataset for a compressor relating compressor operating parameters to each other; detecting real time actual values of the compressor operating parameters including an evaluated operating parameter; using at least one of the real time actual values and the dataset to determine a predicted value of the evaluated operating parameter; and comparing the predicted value of the evaluated operating parameter to the real time actual value of the evaluated operating parameter. This advantageously allows a prognosis of compressor performance to determine whether performance degradation is occurring.
