Abstract

A refrigeration apparatus having an ejector operatively connected with a cold compressor to form a two-stage pumping system. This pumping system is used to lower the pressure, and thereby the temperature of a bath of boiling refrigerant (helium). The apparatus as thus arranged and operated has substantially improved operating efficiency when compared to other processes or arrangements for achieving a similar low pressure.

Combined cold compressor/ejector helium-refrigerator cycle

Conference Schlafke, A P; Brown, D P; Wu, K C

A series of tests is reported as part of the program to demonstrate the feasibility of cold compressors as related to a large refrigerator. The use of a cold compressor in series with an ejector has been shown as an effective way to produce low pressure in a helium refrigeration system. Compared with a system which uses an ejector alone, the combined cold compressor and ejector system produces a lower temperature on the same load or more cooling at the same temperature. (LEW)
Refrigerant pressurization system with a two-phase condensing ejector

Patent Bergander, Mark [Madison, CT]

A refrigerant pressurization system including an ejector having a first conduit for flowing a liquid refrigerant therethrough and a nozzle for accelerating a vapor refrigerant therethrough. The first conduit is positioned such that the liquid refrigerant is discharged from the first conduit into the nozzle. The ejector includes a mixing chamber for condensing the vapor refrigerant. The mixing chamber comprises at least a portion of the nozzle and transitions into a second conduit having a substantially constant cross sectional area. The condensation of the vapor refrigerant in the mixing chamber causes the refrigerant mixture in at least a portion ofmore »« less

Refrigeration system having dual suction port compressor

Patent Wu, Guolian

A cooling system for appliances, air conditioners, and other spaces includes a compressor, and a condenser that receives refrigerant from the compressor. The system also includes an evaporator that receives refrigerant from the condenser. Refrigerant received from the condenser flows through an upstream portion of the evaporator. A first portion of the refrigerant flows to the compressor without passing through a downstream portion of the evaporator, and a second portion of the refrigerant from the upstream portion of the condenser flows through the downstream portion of the evaporator after passing through the upstream portion of the evaporator. The second portionmore »« less

Electrochemical compressor refrigeration appartus with integral leak detection system

Patent Bahar, Bamdad

An electrochemical compressor system, such as an electrochemical refrigeration system includes a sealed vessel that reduces leak issues related to the electrochemical cell. The sealed vessel may be molded or formed from a polymer or a composite polymer having reinforcing materials, such as fibers therein. The sealed vessel may be plated with metal to reduce gas permeation through the wall of the vessel and to accommodate and improve the attachment of conduits, including metal conduits thereto. A metal conduit may be brazed onto a vessel and the brazing material may be selected for polymer to metal joining and for reducedmore »« less
