Abstract: A system has a first compressor and a second compressor. A heat rejection heat exchanger is coupled to the first and second compressors to receive refrigerant compressed by the compressors. The system includes an economizer for receiving refrigerant from the heat rejection heat exchanger and reducing an enthalpy of a first portion of the received refrigerant while increasing an enthalpy of a second portion. The second portion is returned to the compressor. The ejector has a primary inlet coupled to the means to receive a first flow of the reduced enthalpy refrigerant. The ejector has a secondary inlet and an outlet. The outlet is coupled to the first compressor to return refrigerant to the first compressor. A first heat absorption heat exchanger is coupled to the economizer to receive a second flow of the reduced enthalpy refrigerant and is upstream of the secondary inlet of the ejector. A second heat absorption heat exchanger is between the outlet of the ejector and the first compressor.

Abstract: A method of measuring concentrations of gas mixtures is disclosed in which an ionic liquid and/or low vapor-pressure organic solvent is exposed to a gas mixture being tested to form a solution of the gas components in the liquid. The vapor pressure of the solution is then measured at one or more other temperatures and compared to predicted vapor pressures based on known individual vapor pressure profiles of the gas components in the liquid in order to determine the actual proportions of the components in the gas sample.

Abstract: A method for operating a heat pump (20; 300) includes operating in a cooling mode wherein heat is absorbed by refrigerant in the indoor heat exchanger (26) and rejected by refrigerant in the outdoor heat exchanger (24). The heat pump switches to operation in a heating mode wherein heat is rejected by refrigerant in the indoor heat exchanger, heat is absorbed by refrigerant in the outdoor heat exchanger, and there is an ejector (60) motive flow and ejector secondary flow. In the heating mode a refrigerant pressure (PH) or temperature (TL) is measured and, responsive to the measured refrigerant pressure or temperature, at least one of a fan speed is changed and a needle (132) of the ejector is actuated.

Abstract: A cooling system for a variable frequency drive (VFD) of a transport refrigeration unit (TRU) is disclosed. The system comprises a conduit disposed within the vehicle and extending between a opening provided at a first predefined position on the outer body of the vehicle and the VFD being positioned at a second predefined position within the vehicle. The opening facilitates the inflow of ambient air within the conduit that carries the ambient air towards the VFD to enable cooling of the VFD. The system includes a grill cover adapted to be removably attached to the opening and/or the first end of the conduit, which allows entry of the ambient air within the conduit and restricts entry of outside objects and/or living organisms within the conduit.

Abstract: A vapor compression system (20; 120; 220; 320) has: first (22A; 122A; 222A) and second (22B; 122B; 222B) compressors; first (40) and second (46) heat exchangers; and one or more expansion devices (52; 52A, 52B). Means (32A, 32B; 32A, 32B, 126A, 126B; 32A, 32B, 232A, 232B) are provided for switching the system between operation in first and second modes using the respective first and second compressors. In the first mode: the first compressor compresses refrigerant; the compressed refrigerant is cooled in the first heat exchanger; the cooled refrigerant is expanded in at least one of the one or more expansion devices; and the expanded refrigerant absorbs heat in the second heat exchanger. In the second mode: the second compressor compresses refrigerant; the compressed refrigerant is cooled in the second heat exchanger; the cooled refrigerant is expanded in at least one of the one or more expansion devices; and the expanded refrigerant absorbs heat in the first heat exchanger.

Abstract: A method of realizing a ferroic response is provided. The method includes applying a positive or negative conjugate field, which is of a first polarity, to a ferroic material to obtain a substantially minimized entropy of the ferroic material (301) and applying a slightly negative or a slightly positive conjugate field, which is of a second polarity opposite the first polarity, to the ferroic material to obtain a substantially maximized entropy of the ferroic material (302).
