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： A crush tube is used to provide a fluid connection between a first and second member. The crush tube has two tubular portions with a spherical portion therebetween. The tubular portions are loosely received in nominally coaxial bores having entrance chamfers. The spherical portion is deformed into contact with the chamfers as well as between the members whereby the tube provides a sealed fluid path between the bores.

摘要： In a low side hermetic compressor, a small portion of the compressed refrigerant gas is diverted and discharged into the oil sump through an orifice into the upper level of the oil in the sump. This results in a supersaturated solution of refrigerant in oil in the upper level which drives the refrigerant out of the oil, thereby creating froth which provides sound reduction without disturbing the lower level which remains stratified.
